Gingivitis or inflammation of the gingiva, is the commonest oral disease in children and adolescents. It is characterized by the presence of gingival inflammation without detectable bone loss or clinical attachment loss. The causes and risks are as varied in children as in adults and range from local to systemic causes. The most important local predisposing factor in children is poor oral hygiene which stems from children's dependence on adults for assistance with routine oral hygiene. It also stems from age limitation in perception of the need for regular and efficient tooth brushing.

When plaque and food debris accumulate in poor oral hygiene, micro-organisms also accumulate and the process of inflammation starts. This leads to gingivitis, which, if not taken care of can progress to gradual destruction of supporting soft and hard tissues of the teeth. This is evident in the very young and those with disabilities, where manual dexterity is not well developed.

Gingivitis in children is also commonly seen during eruption and exfoliation of both primary and permanent teeth and exfoliation of primary teeth. This process, although physiological, if not managed carefully, may contribute to discomfort during tooth brushing, mastication and also cause restlessness in the affected children. During puberty, it may be a response to hormonal changes in the developing adolescent, though more pronounced when there is plaque accumulation.

In children with compromised immunity, chronic malnutrition, exanthematous fevers such as malaria, measles or chicken pox, the gingivitis may be acute and necrotic. The systemic effect and local destruction of soft and hard tissues may contribute to increased morbidity and poor aesthetics in affected children.

Habitually leaving the mouth open, either spontaneously or due to pathology in the oropharynx, may also contribute to gingivitis. During childhood and adolescence, appliances, either habit breakers or removable and fixed appliances may be required. Most children at this age present with gingivitis. This is a result of non compliance with routine tooth brushing which is further made difficult by orthodontic wires and elastics. One of the pre-conditions for appliance therapy is a commitment to efficient routine tooth brushing because the use of an appliance in the presence of plaque and debris accumulations is deleterious to the periodontal structures.

Gingivitis may also be a complication of chronic use of certain medications whose side effects include dryness of the mouth. It predisposes to gingival inflammation which is due to a low output of saliva. This type of gingivitis is frequently encountered in children and

protective response ensues, resulting in inflammation, recruitment of white blood cells

As the biofilm accumulates, gingivitis develops over a period of several days in the presence of periodontal bacteria (Loe et al, 1965). Gingivitis may be a non-specific bacterial infection

Nevertheless, the prevalence and severity of inflammation of the oral tissues (gingivitis and periodontitis) is low in healthy young children and gradually increases with increasing age (Matsson, 1993; Papaioannou et al, 2009). With increasing age, the proportions of

In health, hallmark features of gingival connective tissue are an even collagen density

In the initial lesion, which occours within 2 to 4 days after allowing plaque to accumulate, an increased volume of junctional epithelium (JE) is occupied by polymorphonuclear leucocytes (PMNL). Blood vessels subjacent to the JE become dilated and exhibit increased permeability. A small cellular infiltrate of PMNL and mononuclear cells forms and collagen

In the Early stage, which is about 4 to 7 days of plaque accumulation, gingivitis in humans evolves at this stage, the differentiating sign being accumulation of large numbers of lymphocytes as an enlarged infiltrate in the connective tissue. There are altered fibroblasts

In the Established stage, which is about 2 to 3 weeks of plaque accumulation, there is preponderance of plasma cells in an expanded inflammatory lesion with continuance of earlier changes. The Established lesion may persist for a long time before becoming

In the Advanced lesion, the infiltrate is dominated by plasma cells. Collagen destruction continues with loss of alveolar bone and apical migration of JE, with "pocket" formation now being apparent. Throughout the sequence, viable bacteria remain outside the gingiva, on the surface of the tooth and in the periodontal pocket against, but not invading the soft tissue. However, a notable finding by Longhurst (1980) is that the histopathology of chronic gingivitis in children corresponds to the plasma cell-dominated established lesion of the adult, but has an inflammatory infiltration with a great majority of lymphocytes. This is analogous to the Early lesion as described by Page and Shroeder (1976) for the adult. Other reports on the nature of cellular infiltrates in various stages of periodontal disease had indicated that in mild gingivitis, the predominant lymphocyte was the T-cell while in more severe gingivitis and peridontitis the B-cell line predominates. This implies that gingivitis in children is T-cell dominated, although the degree of delineation is not quite established. It also indicates an age-related difference in immunologic response (Koch & Poulsen, 2009). In a study assessing the prevalence of three microorganisms, *Porphyromonas gingivalis*, *Actinobacillus actinomycetemcomitans* and *Tannerella forsythensis*, in the bacterial plaque of children with and without gingivitis, it was found that the organisms causing gingivitis were endogenous in healthy mouths.

Several studies on the oral health of the young population in developing countries show that poor gingival health is rampant, especially in those residing in the rural and remote areas and in those of the lower socioeconomic strata. This condition is even more significant in those who are institutionalized, those with intellectual disabilities, for example, Down syndrome, Autism Spectrum Disorders; those with multiple disabilities and generally those who have musculo-skeletal disorders who may not be able to carry out effective tooth brushing. The main problem with these individuals is neglect on the part of parents and care givers who are supposed to be responsible for their daily hygiene. When compared with children and adolescents without disabilities, their oral health has been found to be poorer.

The situation can however be controlled with regular dental visits, which is still alien to the population at large, where oral health education will be re-inforced. The school health programme has also been recommended as an important means by which oral health education can be provided and established for children and adolescents. The programme is being supported by Faculty and corporate bodies across the globe and it is believed that this will gradually expose the population to good oral health practices and improve gingival health. This Chapter aims to discuss the various forms of gingivitis encountered in children and adolescents including those with special health care needs and provide a summary of recommendations given from the different studies carried out.

#### **2. Plaque induced gingivitis**

Gingivitis is also regarded as the most common periodontal disease in children, with the primary aetiology as plaque (Oh et al, 2002). In poor oral hygiene, food debris, plaque and micro-organisms also accumulate and the process of inflammation starts. This leads to gingivitis, which, if not taken care of can progress to gradual destruction of supporting soft and hard tissues of the teeth (Fig 1).

#### **2.1 Histopathology**

Inflammation represents the body's protective response to injury and tissue destruction. This response consists of a spectrum of highly coordinated events that occur at cellular and tissue level. Its purpose is to destroy, dilute or sequestrate the injurious agent and the injured tissue in order to permit healing.

Inflammation is a defensive mechanism intended to protect the host, but can also be potentially harmful. Clinical signs of inflammation are redness (due to open blood vessels), heat (due to warmth of blood), swelling (due to oedema), pain (due to stimulation of pain receptors) and loss of function due to oedema (Ramzi et al, 2002).

Gingival inflammation is the result of plaque or bacterial biofilm. This biofilm develops and matures over a period of several weeks, initially developing supragingivally with mainly aerobic bacteria (Serio et al, 2009). Over time, the flora changes from predominantly gram positive to gram negative, from facultative aerobes to strictly anaerobic species, with more motile forms present. Mature subgingival biofilm takes up to twelve weeks to develop (Lovegrove et al, 2004) and contains gram negative bacteria such as *P. gingivalis, B. forsythus, and P. intermedia*, among many others (Fleming, 1999).

These bacteria possess complex carbohydrate and proteins on their cell walls called endotoxins or lipopolysaccharides (LPS). When these molecules are detected by the host, a

Gingivitis in the maxillary anterior region is also a common finding in mouth breathers (Fig 2). This habit is common among young children and it predisposes to dryness of the gingiva when the lubricating effect of saliva is absent. This habit can be corrected with the use of a removable appliance. Children who use orthodontic appliances for correction of malocclusion are predisposed to gingivitis. However effective tooth brushing and use of

This is gingival inflammation occouring around an erupting permanent tooth. The child may be experiencing discomfort which will therefore make tooth brushing difficult. Sometimes, the child refuses tooth brushing completely. This will lead to plaque accumulation and inflammation. Also during the eruptive phase, the epithelium displays degenerative changes at the site of fusion between dental and oral epithelia. These areas are vulnerable to plaque accumulation and sets up a bacterial reaction (Koch & Poulsen,

which causes low perception of need for adequate oral hygiene. In a recent study among Finnish school children, those whose mothers had a college or university education had a smaller chance of presenting with visible plaque accumulation than those from mothers with a lower educational level (Leroy et al, 2011). The study also found an association between bacterial plaque accumulation and the presence of gingivitis.

Poor oral hygiene and gingivitis have been reported to be more prevalent in children with cognitive and developmental disabilities. The Oral Hygiene Index (OHI) scores have been found to be higher in children and adolescents with disabilities than in control groups in studies carried out in some developing countries (Oredugba, 2006; Oredugba & Akindayomi, 2008; Nahar et al, 2010). In the study carried out in Bangladesh, as many as 64% of those with disabilities had gingivitis compared with 27.5% of controls. The prevalence of gingivitis has also been found to be influenced by other demographic factors such as place of residence, age and severity of disability and cognition.

Since most of the affected children do not brush their teeth, or brush only once a day or occasionally, mouth washes containing chemical anti-plaque agents which reduce bacterial plaque accumulation and therefore the incidence of gingival and periodontal diseases are important in such individuals. Chlorhexidine is currently the most effective chemical antiplaque agent used in dentistry (Twetman, 2004). It causes an immediate reduction in the number of salivary bacteria and possesses a broad spectrum against gram positive and negative bacteria, fungi and lipophylic viruses (Jones, 2000). Its effect is both bactericidal and bacteriostatic and clinical efficacy results from its interaction with bacterial cell membrane causing cell lysis and prevention of adhesion of new bacteria in the oral cavity. These findings point to the need for motivation of parents and caregivers to commence and encourage effective tooth brushing which will lay a foundation for good oral health in their

In a study comparing the oral microbiology of HIV-positive children with that of controls, the prevalence of gingivitis was significantly higher in the HIV-positive group (89.4%) than in the healthy group (40.5%) (Portela et al, 2004). It was also found that the frequency of yeast isolation correlated positively with the severity of the gingival condition in the HIVinfected group, because 95% of infants who presented with Candida had inflammation of the gingivae. In the study, multiple candida species were isolated from the subgingival crevices of children with positive HIV infection. These include *C. albicans, C. dubliniensis, C. globrata and C. tropicalis.* Apart from yeast infection, fusobacterial and spirochaetal infections have been found in HIV positive children, with a high proportion of those who manifested the AIDS disease having necrotizing gingivitis. These findings confirm the multiple

This is an acute multiple bacterial infection of the gingivae. The lesion starts at the interdental papilae, spreading along the gingival margins and if untreated, starts to destroy the underlying connective tissue and bone. There is a characteristic necrotic odour associated with this condition and the mouth becomes progressively painful with sloughing off of the necrotic ulcers on the gingivae. The ulcers become erythematous and bleed following minimal trauma, especially tooth brushing.

#### **4.1 Herpetic gingivo-stomatitis**

Also known as acute herpetic gingivo-stomatitis and affects both the gingivae and other parts of the oral mucus membrane. It is commonly seen in children less than three years of age. It is caused by the herpes simplex virus type 1. Infection usually follows bouts of childhood fevers such as malaria, measles and chicken pox and it may assume epidemic proportions among children attending same pre-school or crèche centres. The onset of generalized gingivitis is preceded by a prodromal period with symptoms such as irritability, malaise, vomiting and fever and the appearance of small vesicles which rupture to reveal small yellowish painful ulcers with erythematous margins. The condition is associated with drooling of saliva, inability to chew and swallow and the child may become increasingly uncooperative during tooth brushing (Fig 3).

The condition is self limiting and the management is to encourage bed rest, plenty of fluid and maintenance of good oral hygiene through gentle debridement. Analgesics are prescribed to relieve the pain and antibiotics are useful in preventing superimposed bacterial infection. The application of a mild topical anaesthetic gel has been found useful in young children and reduces irritability.

Oral manifestations of human immunodeficiency virus (HIV) disease are an important part of the natural history of HIV disease (Lamster et al, 1998). Many studies have reported that hairy leukoplakia, pseudomembranous candidiasis, Kaposi sarcoma, non-Hodgkin's lymphoma, linear gingival erythema, necrotizing ulcerative gingivitis and periodontitis were common lesions seen in patients with HIV infection and AIDS. It was also reported that the higher prevalence and incidence rates of these conditions correlated with the falling CD4 counts and higher viral load of the patients (Han & Liu, 2010).

The bacteria implicated earlier were *Fusobacteria fusiformis and Borrelia vincentii*. However, modern electron microscope studies have shown the lesion to be colonized by various species of gram negative anaerobes and spirochaetes such as *Treponema species, Bacteroides,* 

The treatment of choice is regular gentle debridement of the gingivae and irrigation with an oxidising antiseptic such as hydrogen peroxide, until the infection clears. Diet and oral hygiene counseling is also useful and this should be followed up to ensure speedy healing. Metronidazole is used because it is effective against obligate anaerobes which are found in

Adolescence is a time of rapid growth, independent food choices and food fads. (Bello & Al-Hammad, 2006). It is also a period of heightened caries activity as a result of increased intake of cariogenic substances and inattentiveness to oral hygiene procedures (Majewski, 2001). Biological antioxidants form an important part of our diet and together with intracellular antioxidants and antioxidant enzyme systems may prevent various pathological diseases (O'Brien, 1994; Battino et al, 2002). Saliva, which bathes the oral tissues, contains pure salivary secretions, crevicular fluid, proteins, carbohydrates, enzymes, ions, antioxidants and microorganism, and is usually a reflection of plasma. One of the most important functions of salivary enzymes such as peroxidase is the control of oral bacteria that form dental plaque and imbalance in oral ecology which lead to dental caries and chronic

There is evidence that different foods, such as dietary proteins and carbohydrates can affect the buffering capacity of saliva (Mundorff-Shrestha et al, 1994) and protein deficiency influences markedly the composition of whole saliva in man (Johansson et al, 1984; Agarwal et al, 1984).

For an individual, birth is a borderline between the sterile intrauterine life and the extrauterine existence with a continous exposure to microorganisms (Kononen, 1999). The microbial community is further shaped by diet, personal oral hygiene (Crielaard et al, 2011) and other parameters such as hormones and various systemic conditions. The microbiome analysis by Crielaard et al (2011) showed that the salivary microbiome of children is already complex by the age of three years matures with increasing age, but at the age of puberty, still differs from the adult microbiome. A higher amount of plaque has also been found in the primary dentition compared with the mixed and permanent dentitions, but the prevalence and

intellectual disabilities and some other medically compromising conditions who may not be able to comply with routine oral hygiene practices.

Predisposing factors include poor oral hygiene, malnutrition, depressed immunity and long term hospitalization. It used to be known as "trench mouth" because it was seen frequently in soldiers occupying trenches during the World War I. It was also called "Vincent's angina", after the French physician Henri Vincent (1862- 1950). Later, it was seen in children from low socio-economic families who were malnourished and with poor oral hygiene.

The bacteria implicated earlier were *Fusobacteria fusiformis and Borrelia vincentii*. However, modern electron microscope studies have shown the lesion to be colonized by various species of gram negative anaerobes and spirochaetes such as *Treponema species, Bacteroides, Veilonella, Fusobacteria and Actinomyces.* 

The treatment of choice is regular gentle debridement of the gingivae and irrigation with an oxidising antiseptic such as hydrogen peroxide, until the infection clears. Diet and oral hygiene counseling is also useful and this should be followed up to ensure speedy healing. Metronidazole is used because it is effective against obligate anaerobes which are found in large numbers in the lesion. To prevent secondary infection, penicillin is prescribed.

#### **5. Malnutrition-induced gingivitis**

Adolescence is a time of rapid growth, independent food choices and food fads. (Bello & Al-Hammad, 2006). It is also a period of heightened caries activity as a result of increased intake of cariogenic substances and inattentiveness to oral hygiene procedures (Majewski, 2001).

Biological antioxidants form an important part of our diet and together with intracellular antioxidants and antioxidant enzyme systems may prevent various pathological diseases (O'Brien, 1994; Battino et al, 2002). Saliva, which bathes the oral tissues, contains pure salivary secretions, crevicular fluid, proteins, carbohydrates, enzymes, ions, antioxidants and microorganism, and is usually a reflection of plasma. One of the most important functions of salivary enzymes such as peroxidase is the control of oral bacteria that form dental plaque and imbalance in oral ecology which lead to dental caries and chronic inflammatory periodontal diseases (Tulunoglu et al, 2006).

There is evidence that different foods, such as dietary proteins and carbohydrates can affect the buffering capacity of saliva (Mundorff-Shrestha et al, 1994) and protein deficiency influences markedly the composition of whole saliva in man (Johansson et al, 1984; Agarwal et al, 1984). Chronic deficiencies of iron, the B group vitamins and folic acid also predispose to glossitis and gingivitis, especially in young children.

#### **6. Gingivitis associated with hormonal changes**

Hormones have been found to have strong effects on mucosal, connective tissue and bones. For an individual, birth is a borderline between the sterile intrauterine life and the extrauterine existence with a continous exposure to microorganisms (Kononen, 1999).

children with severe mental retardation as compared with healthy children, in spite of similar frequencies of dental care (Forsberg, 1985). This has been attributed to their lack of cooperation during tooth brushing at home and during treatment. A lot of patience is required by parents and care givers in order to provide effective home oral hygiene care for this group of individuals. Oral health education is also desirable to create awareness of need

for good oral health for all individuals, irrespective of age and mental status.

severity of inflammation of the oral tissues (gingivitis and periodontitis) is low in healthy young children and gradually increases with increasing age (Papaioannou et al, 2009).

Pubertal gingivitis has been seen with increasing frequency in young teenagers and has been ascribed to the "rush" of sex hormones which also affects the reaction of tissues to corticosteroids. The same pattern has been described in pregnant women who are more predisposed to gingivitis during pregnancy. The condition ranges from localized inflammation of one or two papillary gingivae, also called 'pregnancy epulis', to generalized marginal gingivitis. This condition is not severe if plaque is well controlled. Most cases resolve as soon as debridement is commenced.

#### **7. Drug-induced gingivitis**

Drug-induced gingival enlargement (DIGE) and gingivitis are side effects and unwanted outcomes of antiepileptic therapy with phenytoin, or immunosuppressive therapy with systemic cyclosporine. Patients on these medications develop varying degrees of gingival overgrowth (Trackman & Kantaki, 2004; Cury et al, 2009). Gingival enlargement is the most significant oral finding (Robbins, 2009) and can occour in up to 50% of patients taking Phenytoin (Thomason et al, 1992). Valproic acid and Carbamazepine have also been demonstrated to cause gingival enlargement, especially on the labial surfaces of the anterior maxillary and mandibular teeth (Figs 7a & 7b). It is strongly correlated to poor plaque control. Where the oral hygiene is good and food debris and plaque are not allowed to accumulate, this side effect of anticonvulsive therapy is not observed or not so significant. Treatment includes meticulous oral hygiene and in severe cases where the enlarged tissue interferes with function and aesthetics, surgical resection is advised. (Robbins, 2009). A more frequent recall and oral hygiene interval has also been suggested for such patients on antiepileptic drug therapy to reduce the risk of gingival hyperplasia.

#### **7.1 Plasma Cell Gingivitis (PCG)**

Plasma cell gingivitis is characterized by diffuse and massive infiltration of plasma cells into the subepitheial gingival tissue (Macleod & Ellis, 1989). It is a rare benign inflammatory condition with no clear aetiology, but an exaggerated response to bacterial plaque, immunological reaction to allergens in food such as strong spices, chilli pepper, medications, toothpaste or herbs such as khat has been reported (Halbach, 1972; Kalix, 1988; Macleod & Ellis, 1989; Serio et al, 1991; Marker & Krogdahl, 2001). The diagnosis requires haematological screening in addition to clinical and histopathological examination in order to exclude leukemia. Further, serological examination is needed to exclude connective tissue disease – first and foremost lupus erythematosus (Al-Meshal, 1988; Neville et al, 1995). In affected children, standard professional oral hygiene procedures and non- surgical periodontal therapy including antimicrobials are associated with marked improvement of clinical and patient related outcomes (Arduino et al, 2011).

#### **8. Gingivitis as a manifestation of systemic disease**

Subjects with developmental disabilities, mental retardation, cerebral palsy and autism have been shown to require special care for maintaining oral hygiene and receiving dental treatment (Surabian, 2001 A & B; Oredugba & Akindayomi, 2008).

#### **8.1 Gingivitis and orofacial clefts**

Children with clefts have been found to show an increase in gingival inflammation when compared with control subjects (Lucas et al, 2000; Perdikogianni et al, 2009)). The cleft deformity, the soft tissue folds, the shallow vestibule, the dental arch irregularities, the long term orthodontic treatment and scar tissue observed in the region, after surgical closure of the cleft defect hinder optimal oral hygiene control (Stec et al, 2007). Parents and care givers should be educated on the method of plaque control as early as possible after presentation in the dental clinic to control plaque, thereby reducing inflammatory gingival and periodontal diseases. For the very young patients, chlorhexidine wipe after careful toothbrushing will reduce bacterial load and recurrent respiratory tract infections which follow aspiration of oral contents.

#### **8.2 Gingivitis and neuromuscular disorders**

Reduced muscle strength and motor function characterize conditions such as cerebral palsy (CP), poliomyelitis, myotonic dystrophy and Duchenne muscular dystrophy. Individuals affected by these conditions also have oral motor dysfunction, impairment of lip and tongue motility, lip force and chewing capacity which contribute to poor oral self cleansing ability and plaque and calculus accumulation. Several studies have shown poor oral hygiene and a higher prevalence of gingivitis and periodontal disease in these groups of individuals (Balasubramaniam et al, 2008; Symons et al, 2002; Engvall et al, 2009). According to findings from a recent study of a group of Nigerian individuals with CP and controls, gingivitis was more prevalent among those with CP (Oredugba, 2011). Mouth breathing and food pouching contribute to gingivitis especially in the anterior region in individuals with CP (Scully & Cawson, 2005). Gingival and periodontal diseases have been reported to be common, especially in older children with CP due to poor oral hygiene and complications of oral habits, physical disabilities, malocclusion and gingival hyperplasia caused by medications (National Institute of Dental and Craniofacial Research, 2004). Mouth breathing worsens the periodontal state and papillary hyperplastic gingivitis may be seen even in the absence of phenytoin (Scully & Cawson, 2005). Early routine oral care and close supervision will prevent the untoward consequence of periodontal disease.

#### **8.3 Gingivitis and metabolic conditions**

Diabetes mellitus (DM) is one of the most common chronic metabolic diseases of glucose metabolism which affects almost all the organs of the body. The Type 1 DM is the juvenile onset type which affects young people. Diabetes-related abnormalities include impaired hepatic glucose uptake, alterations in immune function, early cellular senescence and premature apoptosis (Crofford, 1995; Acikgoz et al, 2004). The oral environment is characterized by the presence of moisture, warmth and a constant reservoir of micro organisms and so, individuals with diabetes are at increased risk for oral diseases such as gingivitis and periodontal disease. Good and sustained glycaemic control will however reduce this risk considerably.

#### **8.4 Gingivitis and haematological conditions**

Gingivitis may be seen in patients affected by haematological conditions such as haemophilia, aplastic anaemia and leukaemia. Oral hygiene maintenance may be impaired because of their reluctance to brush their teeth for fear of increased gingival bleeding (Oyaizu et al, 2005). In very young children, the gingival bleeding may be experienced for

Patients with aplastic anaemia have a weak immune response due to the concurrent immuno suppressive therapy and neutropenia (Agnihotri et al, 2009). Opportunistic infections from normal oral bacteria, periodontal pathogens or mixed odontogenic pathogens may also develop.

Oral findings in aplastic anaemia include gingival haemorrhage, mucosal petechiae, purpura and ecchymoses due to thrombocytopaenia (Neville et al, 2004). Ulcerative lesions with erythematous margins, especially of the gingiva, may develop in association with secondary infection (Oyaizu et al, 2005). Gingival hyperplasia, swelling and submucosal haemorrhage may also be present (Luker et al, 1991; Brennan et al, 2001). Patients with leukaemia present with bleeding diathesis, petechiae, oral ecchymosis, gingival haemorrhage and progressive gingival enlargement (Weckx et al, 1990; Genc et al, 1998). The change in gingival morphology and its cyanotic appearance may result from reactive hyperplasia, dense leukaemic infiltration of connective tissue and compression of local vasculature, causing ischaemia (Abdullah et al, 2002; Cooper et al, 2000). Caries, calculus and poor oral hygiene, place the patient at risk for oral pain, bleeding, super infection and tissue necrosis, exacerbating gingival signs and symptoms (Cooper et al, 2000).

Severe persistent gingival inflammation and stomatitis are some of the features of severe congenital neutropenia heightened by susceptibility to bacterial infections due to impaired bone marrow myelopoiesis and an absolute neutrophil count (ANC) in the peripheral blood of < 0.2 x 10 9/L (Okada et al, 2001; Zeidler et al, 2009). Periodontal manifestations may range from marginal gingivitis to rapidly progressive periodontal disease with advancing bone loss, which may affect both primary and permanent dentitions, but primarily the permanent dentition (Zeidler et al, 2000). Although an individual's susceptibility to gingivitis and periodontal disease is influenced by many factors such as systemic diseases and genetics, evidence indicates that prevention of gingival inflammation by dental plaque control reduces the severity of disease in this group of individuals (Antonio et al, 2010). Such individuals should be motivated to maintain good oral hygiene. In most haematologic conditions, the most important part of patient management is making the patients and their relatives aware of the importance of preventive measures and the need for medical as well as dental appointments at appropriate intervals (Ranjith et al,2008).

While it is difficult to determine the relative importance of each aetiologic or facilitating factor for gingival and periodontal diseases, there is increasing data that indicates that environmental, dietary, behavioural and systemic factors, (including the genetic complement of the host) have an important role in gingival and periodontal disease initiation, progression and response to treatment (Hart, 2001; Shenkein, 2001)

#### **9. Conclusion**

Several factors such as genetics, systemic conditions, medications, diet and individual host response to infection have been identified in the aetiology of gingivitis in children. However, the most significant facilitating factor is dental plaque which could be controlled by mechanical means and use of topical chemical agents. Parents, relatives and care givers should be educated on the need for effective plaque control to prevent the condition.

Health promotion is the science and art of helping people and society change their lifestyles to achieve optimal health. It places an emphasis on improving quantity and quality of life for all and enables the improvement of health. Therefore, health promotion includes the use of any preventive, educational, administrative policy, program, or law to achieve this outcome. (1, 2, 3) Health promotion practice and policy is currently undergoing a process of fundamental change. The focus of many health education interventions has been on defined diseases, targeted at changing the behaviors of high-risk individuals. Health professionals have dominated this approach in terms of programme development, implementation, and evaluations. This health education model has been very popular with the dental profession as it fits the clinical approach to care and treatment of individual patients. Recent effectiveness reviews of the oral health education and promotion literature have however, recognized the limitations of many educational interventions to produce sustained improvements in oral healths. Another one of the common finding of the reviews was the

Oral health is a vital part of general health and hence affects the total well-being of individuals; thus, special attention must be given to this subject. Health education is part of the wider aspect of oral health promotion which involves local, national and even international cooperation. Oral health promotion attempts to make the healthier choices (9). Oral health promotion has developed and progressed a great deal in the last 20 years. In line with developments in public health, oral health promotion has changed focus to encompass a broader approach. It is important to highlight these developments as they are very relevant to the way in which oral health promotion interventions are evaluated (10, 11, 12). Oral health promotion is aimed at four preventable oral diseases: dental caries, disease of supporting structures, oral pharyngeal cancers, and craniofacial injuries. The poor, minorities, and the elderly share a disproportionate amount of preventable oral disease. Since prevention is vital to health promotion, the goal of any oral health program should be to empower people to attain equity in health and to reduce the incidence and prevalence of
