**4.4 Dentin monitorization**

Laser fluorescence readings of under 20 in the presence of positive visual inspection findings are suggestive of dentin caries. Fissure aperture would be indicated with LF readings of over 20.

#### **4.5 Dentin caries**

Enamel aperture with a diamond drill, followed by elimination of the caried dentin with adequate instruments, is indicated in the case of dentin caries. Filling with resin composites or silver amalgam should follow. Ceramic incrustations may be considered in the case of important tooth involvement.

Both the described intervention protocol and the specified treatments cannot encompass all the possible clinical situations. Likewise, they cannot replace clinician experience and the global vision afforded by all the diagnostic techniques, the tooth and oral conditions, and even the individual conditions of each patient. However, the information provided may serve to establish bases and guidelines for intervention and recommendations fundamented on experience and research.

Malocclusions are defined by different clinical signs, dental, aesthetic, functional and skeletal parameters. Numerous local factors can interfere with the adequate maxillary and mandible growth, which it can induce to the development of dentoskeletal alterations

The Orthodontic or Orthopedic treatment is the indicated option to solve these problems; placement of fixed appliances in mouth increases risk of enamel demineralization; the braces, archwires, ligatures and other orthodontic appliances complicate the use of

Malocclusion is the third place in the oral diseases, the occurrence of occlusal anomalies varies between 11 al 93%; the complications that it brings could be: psychological derived from the alteration of the dentofacial aesthetics; oral function problems, including difficulties in the mobility of the jaw, pain or disorders in the temporomandibular joint and problems to chew, to swallow or to speak; and finally, problems of major susceptibility to traumatism,
