Knowledge and awareness of polycaprolactone and its applications as provisional material in prosthodontic practice: A questionnaire-based survey.

Aim: The present study was done to evaluate the knowledge and awareness of different provisional materials, especially polycaprolactone (PCL) and their application in prosthodontic practice.

Setting And Design: A questionnaire based survey was carried out to assess the knowledge and awareness of PCL and its applications as provisional material in prosthodontic practice.

Materials And Method: A questionnaire-based descriptive study consisting of 10 questions related to different provisional materials and their applications in prosthodontic practice was formulated on Google Forms.

A comparative evaluation of bond strength of feldspathic porcelain to nickel-chromium alloy, when subjected to various surface treatments: An in vitro study.

Purpose Of The Study: The purpose was to evaluate the effect of various surface treatments and sandblasting with different particle size on the bond strength of feldspathic porcelain with predominantly base metal alloys, using a universal testing machine.

Materials And Methods: Totally, 40 specimen of nickel-chromium alloy were prepared in an induction casting machine. The groups divided were as follows: Group I-sandblasted with 50 μ Al2O3, Group II-sandblasted with 110 μ Al2O3, Group III-sandblasted with 250 μ Al2O3 and Group IV-sandblasted with 250 μ Al2O3, followed by oxidation and again sandblasted with 250 μ Al2O3.
