**6. Oral hygiene maintenance in mixed dentition**

The mixed dentition is the period when maximum dental trauma cases occur. Professional oral hygiene like scaling and root planning can be rendered to the patients in this age group.

Tooth brushing with soft bristled brush with caution in the traumatic areas is advised. Dental flossing to keep the interdental areas clean and prevent inter dental plaque accumulation has to be incorporated in the oral hygiene practice. It is important to check for the trauma to the tooth buds of permanent teeth and render treatment accordingly. If the patient is accustomed to using powered toothbrush, he or she needs to be careful while brushing around teeth with dental trauma. The use of mouthwashes to reduce plaque growth helps in easy oral hygiene maintenance. If the teeth are splinted for stabilization during healing phase, use of interdental brushes such as proxa brush is advised to keep the interdental regions clean.

## **7. Oral hygiene in dental trauma of permanent dentition**

In the permanent dentition oral hygiene around the traumatized teeth becomes vital and post trauma care is essential for long term prognosis. The teeth with traumatic injuries may have cracks, fractures, luxation or may be replanted and this alters the natural shape and structure of the teeth. Many different oral hygiene methods have to be followed to maintain hygiene around these teeth. It is better to have supragingival prosthesis of the fractured tooth as subgingival placement of the crown margin is plaque accumulating and leads to periodontitis if not well maintained.

### **8. Oral hygiene maintenance in special situations**

Oral hygiene maintenance methods have to be modified to meet the special clinical situations.

#### **8.1 Splinted teeth**

The splint should be placed on the buccal surfaces of the maxillary teeth to enable lingual access for endodontic procedures and to avoid occlusal interference [31–34].

Splinting up to four months is advised in root fractures at the cervical third [13]. The use of semi rigid splint and flexible splints is more indicated than the rigid one as per The International Association of Dental Traumatology (IADT), and splinting done for long periods can cause root resorption or ankylosis of teeth [35, 36].

Care must be taken in teeth which are splinted during the healing phase. Interdental cleaning under and over the wire or fiber splint can be carried out with an interproximal brush.
