Ultrasonic versus high-speed cavity preparation: Analysis of increases in pulpal temperature and time to complete preparation
(Mosby-elsevier, 2008-08-01)
Statement of problem. The use of ultrasonic tips has become an alternative for cavity preparation. However, there are concerns about this type of device, particularly with respect to intrapulpal temperatures and cavity ...

Evaluation of Ultrasonic and ErCr:YSGG Laser Retrograde Cavity Preparation
(Elsevier B.V., 2009-05-01)
Root end cavity preparation techniques aim to create a clean and properly shaped cavity in a short time. Although the use of ultrasonics has been widely recommended, a laser can also be used. This study evaluated the time ...

Does overlay preparation design affect polymerization shrinkage stress distribution? A 3D FEA study
(2020-01-01)
This study evaluated the polymerization shrinkage stress of three tooth preparation designs for indirect ceramic overlay by finite element analysis: isthmus preparation (IST); without isthmus preparation (wIST); and ...
Marginal leakage evaluation of three endodontic sealers according to the moment of post preparation
(2012-01-01)
Objectives: The purpose of this in vitro study was to evaluate the coronal marginal leakage after post space preparation in teeth filled with three different sealers, according to the period between the root canal filling ...
Finite element analysis of the influence of geometry and design of zirconia crowns on stress distribution
(Wiley-Blackwell, 2015-02-01)
Purpose: To evaluate the influence of the geometry and design of prosthetic crown preparations on stress distribution in compression tests, using finite element analysis (FEA). Materials and Methods: Six combinations of ...
