Association between oxidative stress and temporomandibular joint dysfunction: A narrative review.

Background: The role of oxidative stress in temporomandibular disorders (TMDs) has been studied using synovial fluid, to evaluate oxidative stress (im)balance and its potential role in the onset and/or progression of the disease.

Objective: This review aimed to evaluate the association between oxidative stress markers and the etiopathogenesis of TMJ dysfunction by means of synovial fluid analysis.

Methods: Two independent reviewers searched the electronic databases from inception to March 2019: PubMed/MEDLINE, LILACS, SciELO, EMBASE, TRIPDATABASE, SCOPUS, and Google Scholar.

Does the Misfit Volume of Prosthetic Crowns Differ Before and After Ceramic Application? An In Vitro Radiographic Microtomography Analysis.

Purpose: To estimate the misfit volume of zirconia vs metal-ceramic crowns.

Materials And Methods: Five specimens were fabricated from zirconia and five from nichrome (metal-ceramic). Microcomputed tomography techniques were used to obtain volumetric reconstructions of misfit volume before and after ceramic application.
