Answer: b Approximately 6mm thickness of investing medium is recommended between the end of the mold to cavity and the end of the invested casting ring to provide pathways for sufficient gas escape during casting and to withstand the impact force of molten alloy during casting process.

Answer: a this picture shows testing of diametral tensile strength. Although a compressive force is applied along the side of the disk, a tensile fracture is produced. The tensile strength is calculated from the fracture load P, the disk diameter D, and the thickness t. Tensile strength can generally be determined by subjecting a rod, wire, or dumbbell-shaped specimen to tensile loading. Since this test is quite difficult to perform for brittle materials because of alignment and gripping problems, another test can be used to determine thisproperty for brittle dental materials. It is referred to as the diametral tensile (compression) test

Answer: b Localized shrinkage porosity in the picture caused by the retention of heat by the pontic because of its bulk and because it was located in the heat center of the ring. This problem can be solved simply by attaching one or more small gauge sprues (e.g., 18-gauge) at the surface most distant from the main sprue attachment and extending the sprue(s) laterally within 5 mm of the edge of the ring. These small chill-set sprues ensure that solidification begins within the sprues, and they act as cooling pins to carry heat away from the pontic.

Very useful, sir please make more videos about other topics of community dentistry

Thankyou

Wow. everything is clear

Congratulation Sandeep!

Congrats bro 👍👍

Well done Sandeep👍 Congratulations!

Please upload a demo lecture of medicine or pharma! Me and my friends are thinking of joining online dental pulse course.

Sir... i have only dental pulse book for neet prep... is it ok... or any other book i should follow with this book

Congratulations.🤗🤗

is it enough to solve dental pulse que to secure good marks or we have to study extra also

How much you scored in the exam Sir?

What books to use for AIIMS sir

Aiims PG 2018- RECALL th-cam.com/video/YdzVfRe_2ZU/w-d-xo.html

A lovely gesture of goodwill!! Congratulations:)

Very nice sir ...

Why are you telling lie

Congratulations doctor
