A true combined lesion results from the development and extension of an endodontic lesion into an
existing periodontal lesion (pocket).
a) True

Centric relation is the position of the mandible when both condyle-disc assemblies are in their most
__________ position in their respective glenoid fossa and against the slope of the articular eminence
of each respective temporal bone.
a) Anterior
b) Posterior
c) Superior
d) Lateral - ✔ ✔ c
Centric relation is the position of the mandible when both condyle-disc assemblies are seated in their
most superior position in their respective glenoid fossa and are braced against the slope of the
articular surface of the temporal bone.

During a routine initial periodontal examination, this patient opened his mouth, and the mandible was
observed to move sharply to the left. A panoramic image revealed a lesion affecting the left condyle and
reduced joint space in the left TMJ, whereas the right condyle appeared to be normal. The most likely
explanation for the observed pattern of mandibular movement during opening would be that:
a) The left condyle rotates but cannot translate, whereas the right condyle freely rotates and translates
b) The left condyle translates but cannot rotate, whereas the right condyle freely rotates and translates
c) The left condyle cannot rotate or translate, whereas the right condyle freely rotates and translates
