Malocclusion in which the mandible is caudal to the maxilla is termed: Class 3 mandibular mesioclusions Class 2 mandibular distoclusions Class 1 neutroclusions Dental malocclusion

Class 2 mandibular distoclusions Class 2 malocclusion or mandibular distoclusion is an abnormal rostral-caudal relationship of the maxillary and mandibular arches. The mandibular arch occludes caudal (distal) to its normal position relative to the maxillary arch. Class 3 malocclusion or mandibular mesioclusion is an abnormal rostral-caudal relationship of the maxillary and mandibular arches. The mandibular arch is rostral (mesial) to its normal position relative to the maxillary arch. Class 1 malocclusion or neutroclusions is a normal rostral-caudal relationship of the maxillary and mandibular arches with malposition of one or more individual teeth. Dental malocclusion is a malocclusion caused by the abnormal positioning of one or more teeth.

Two tooth buds that grow together to form one larger tooth is referred to as Gemini Fusion Polydontia Oligodontia

Fusion Fusion tooth is when two separate-forming tooth structures join to form a single structure, which can sometimes occur at the root. When this occurs, there will be one less tooth than normal. Gemini tooth is an incomplete separation of two teeth usually resulting in two crowns sharing one root system. Polydontia is more teeth than the normal number (also known as supernumerary teeth). Oligodontia is a decreased number of teeth, also known as hypodontia

The purpose of fluoride treatment is to: Prevent thermal damage and lubrication Strengthen enamel and help desensitize teeth Correct Remove plaque and strengthen the enamel Incorrect Irrigate and lubricate

Strengthen enamel and help desensitize teeth Fluoride reduces sensitivity when applied over exposed dentinal tubules. Fluoride forms fluoroapatite, causing the tooth surface to be strengthened and more resistant to the cariogenic bacteria that dissolve enamel. When polishing teeth, the use of the appropriate amount of prophy paste prevents heat buildup resulting from the spinning motion of the prophy angle on the tooth surface. The prophy paste also provides lubrication so the prophy angle spins more freely. Constant irrigation helps prevent heat buildup in the tooth when power scaling. Power scalers use water to keep the tip cool. It is important to ensure that the water flow has a fine mist. The fine mist will keep the tip cool enough and will provide irrigation but not cause the patient's head to become drenched, which can lower the body temperature.
