Endodontic and Surgical Management of External Cervical Root Resorption: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT This study describes the treatment of tooth #9 exhibiting external cervical root resorption (ECR) and apical root resorption. A therapeutic approach—including root canal therapy with MTA apexification, surgical debridement of resorptive tissue at the ECR site, and sealing of the defect—was necessary to eliminate the infection.

Metalorganic Titanium Treatment to Change Enamel Optical Properties

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 9, September 2026.
ABSTRACT Observational studies have shown that human teeth with higher concentrations of titanium traces have better optical properties. The aim of this study was to investigate how titanium ion infiltration into tooth enamel affects its optical properties by studying the diffusion and reactivity of titanium compounds in tooth enamel and how this ...
