Public Health DentistryDental plaque is a bacterial biofilm that forms on the teeth and is a common factor in the development of both dental caries and periodontal disease. While fluoride in drinking water can help prevent dental caries, it is not directly related to periodontal disease. Nutritional disturbances can affect the overall health of the individual but are not the sole cause of either
condition. Disturbed occlusion may be a risk factor for certain dental issues but is not universally common to both diseases.

Conservative DentistryExplanation: In a conventional Class III amalgam cavity
preparation, the axial wall should be straight and parallel to the long axis of
the tooth. This design ensures that the restoration has adequate resistance form
and is less likely to dislodge under occlusal forces. The wall being deeper
incisally than gingivally helps to maintain the integrity of the tooth structure
and provides a stable base for the amalgam restoration.

a. Adamantinoma is a rare tumor arising from the diaphysis of the long bone.
b. The most common long bone affected by adamantinoma is TIBIA.
c. In head and neck , the most common bone affected by adamantinoma is MANDIBLE.
d. In mandible, the most common site is the region of 3RD MOLAR.
e. Classic adamantinomas usually occur in patients older than 20 years, whereas
differentiated adamantinomas occur almost exclusively in patients younger than
20 years.
f. In addition, the 2 classifications of adamantinomas have distinct
radiographic and histologic differences.
g. Patients with adamantinomas present with variable signs and symptoms; most
commonly, they report pain and swelling.
h. The tumor is slow growing, and patients may describe discomfort lasting
months to years.
i. Treatment options for adamantinoma are surgical and include either marginal
or en bloc resection.
j. Unfortunately, neither radiation therapy nor chemotherapy has been proven
effective in the treatment of this insidious tumor.
k. The investigation of choice for adamantinoma is CT SCAN which shows cortical
destruction involving the diaphysis of the bone with surrounding periosteal
reaction.
