EndodonticsIn endodontics, the primary goal of using gutta-percha is to achieve a proper seal at the apex of the root canal system. A definite apical seal is crucial to prevent the ingress of bacteria and fluids, which can lead to reinfection. While the cone should fit well within the canal, the emphasis is on achieving a good seal rather than merely fitting exactly at the apex or being 2 mm from it.

ProsthodonticsExplanation: Monson's spheric theory of occlusion suggests that all cusps and
incisal edges of the teeth should conform to a sphere with an 8-inch diameter,
with the center of the sphere at the glabella, which is the most anterior and
superior point on the midline of the frontal bone of the skull. This concept is
used to achieve balanced occlusion in complete dentures.

Oral SurgeryThe elevator can be used to advantage in scenarios where multiple adjacent teeth
are to be extracted, as it provides a more precise and controlled method of
elevating the teeth, especially when they are closely spaced or have converging
roots.
