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.
l. On x ray there is a characteristic SOAP BUBBLE appearance.

Explanation: It is caused by a gram-negative fungus: This statement
is not true. Thrush is caused by Candida albicans,
which is a yeast (fungus) but not a gram-negative organism. In fact, fungi
are not classified as gram-positive or gram-negative in the same way that
bacteria are. Candida is a eukaryotic organism and does not fit
into the gram classification system. It is characterized by a plaque of proliferating epithelial and
other cells: This statement is true. Thrush
presents as white patches or plaques in the oral cavity, which consist of
fungal elements, dead epithelial cells, and inflammatory cells. It is a complication of immunosuppression or systemic disease:
This statement is true. Thrush is commonly seen in
individuals who are immunocompromised, such as those with HIV/AIDS, cancer
patients undergoing chemotherapy, or individuals on long-term corticosteroid
therapy. It can affect neonates in an epidemic fashion: This
statement is true. Thrush can indeed affect neonates,
particularly those born to mothers with vaginal candidiasis, and outbreaks
can occur in neonatal intensive care units.

RadiologyWaters projection is useful for evaluating all the mentioned structures: frontal and ethmoidal sinuses, maxillary sinuses, and zygomaticofrontal sutures with nasal cavity. It provides comprehensive visualization of the middle third of the face and paranasal sinuses.

The center of rotation (COR) is the point around which a body rotates when a force is applied.For pure intrusion (bodily movement along the tooth/s long axis with no tipping), the center of rotation is located at infinity.This means the entire tooth moves vertically without any angular change.

Boggy gums can be seen in both pregnancy and leukaemia.
Pregnancy: Hormonal changes during pregnancy can increase blood flow to the
gums, making them more sensitive, swollen, and prone to bleeding, which can be
described as boggy.
Leukaemia: In some forms of leukaemia, particularly acute myeloid leukaemia,
cancerous cells can infiltrate the gums, leading to swelling, bleeding, and a
boggy appearance.
Polycythaemia: While polycythaemia involves an increase in red blood cells, it
does not typically cause the characteristic boggy gum appearance in the same way
as pregnancy or leukaemia.

Public Health Dentistry
In epidemiology, incidence refers to the number of new cases of a disease or
condition that occur within a specific time frame in a defined population.
Dental caries, also known as tooth decay, is a common chronic condition where
bacteria in the mouth produce acids that destroy the tooth enamel and underlying
dentin, leading to cavities. The incidence of dental caries would be the number
of new cases of tooth decay diagnosed within a given period, say a year or
another time interval.
Point prevalence, on the other hand, is the proportion of a population that has
a specific condition at a particular point in time. It is a measure of the
prevalence of dental caries at a single moment, which does not account for new
cases or recoveries.
Period prevalence is the proportion of the population that has had a particular
condition during a specific period of time, such as a year or a month. This
measure includes both new cases and cases that have persisted from before the
start of the period in question.

A condenser that is considered user-friendly typically has a high elastic limit and high springiness, allowing for better control and easier placement of the restorative material.

EndodonticsThe main disadvantage of calcium hydroxide in deciduous tooth pulpotomy is internal resorption, which can occur when inflamed pulp tissue remains. This is why formocresol or ferric sulfate are preferred for primary teeth.
