Resilience is the amount of energy absorbed by a structure when it is stressed to proportional Limit.

The elastic area of the stress-strain graph gives resilience; entire area up to breaking point is a measure of toughness.

The slope of straight Line gives Young’s modulus.

In 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.

Which of the following is likely to occur if the VDO is increased in a complete denture patient: clicking of teeth.

Cells die by one of two mechanisms – necrosis or apoptosis • Two physiologically different processes – Necrosis – death by injury – Apoptosis – death by suicide Appoptosis: Disintegration of cells into membrane-bound particles that are then eliminated by phagocytosis or by shedding.

For permanent deformation following strain in compression, ranking is mentioned below:

Polysulfide > polyethers > condensation silicone > addition silicone
