Clinical
class in endodontics was held at our New Delhi centre. Pit and fissure sealant,
pulpectomy, pulpotomy and apex genesis were discussed. The class was followed
by a demonstration of sealant placement.
Pit and fissure sealants are materials that are applied to the pits and
fissure surfaces of teeth to create a thin barrier which protects the sealed
surface from decay. Sealants are a safe and
painless way of protecting teeth from decay. A sealant is a protective plastic
coating, which is applied to the biting surfaces of the back teeth. It forms a
hard shield that keeps food and bacteria from getting into the tiny grooves in
the teeth and causing decay. Such classes are regularly conducted at AHEAD
Academy, New Delhi and Mohali.
A
demonstration of tooth preparation was given to the new batch of students at AHEAD
Academy, New Delhi. After that students practiced tooth preparation on many
patients. The faculty then cleared the doubts of students to improve their
preparations. The four main categories of crown were metal, ceramic,
metal-ceramic and composite. Tooth preparations need to reflect the different
requirements of these materials in terms of amount of space needed to
accommodate the crown and its marginal configuration. Tooth preparations also
need to be free from undercuts whilst reliably retaining the crown.
Online
live class was conducted at AHEAD Academy, New Delhi. The topic of discussion
was “screening for oral diseases”. The topics related to MCQs frequently asked
in exams were explained in detail. The topics related to screening including
sensitivity, specificity and predictive values were discussed. Students can
attend such classes from their homes or anywhere they find it comfortable. It
is similar to classroom teaching where students can ask their doubts that are
answered by the expert faculty. The class was attended by students preparing
for MDS Exams at AHEAD Academy, New Delhi and Mohali.
Receiver
Operating Characteristic curve (or ROC curve) was taught to the students. It is
a plot of the true positive rate against the false positive rate for the
different possible cut points of a diagnostic test.
An
ROC curve demonstrates several things:
·
It shows the trade-off between
sensitivity and specificity (any increase in sensitivity will be accompanied by
a decrease in specificity).
·
The closer the curve follows the
left-hand border and then the top border of the ROC space, the more accurate
the test.
·
The closer the curve comes to the
45-degree diagonal of the ROC space, the less accurate the test.
