Evaluation of the accuracy values of cone-beam CT regarding apical periodontitis: a systematic review and meta-analysis.

Specialists need to know how accurate and effective each radiographic procedure is, and which ones can provide better images for bone resorption around the apical periodontitis. Therefore, the researcher decided to conduct the present study with the aim of evaluate the accuracy values of cone-beam CT regarding apical periodontitis. The PubMed, Embase, ISI, Scopus, and Medicine have been used to search articles over the last 15 years between 2005 and December 2020.

Effect of different debonding techniques on shear bond strength and enamel cracks in simulated clinical set-ups.

Objective: The aim of this study was to evaluate the relationship between debonding forces and enamel cracks length change between different debonding techniques.

Methods: 80 extracted premolar teeth with intact buccal enamel were divided into five groups. In each group, enamel cracks were evaluated by stereomicroscope before and after debonding.
