Effectiveness of self-etching bonding systems on dentin after radiotherapy: perspectives on microtensile and microshear bond strength.

Objective: Self-etching dental adhesives bond with dentin through chemical reactions with calcium. This study assessed bond strength (BS) using microtensile (µTBS) and microshear (µSBS) tests on sound and post-radiotherapy dentin, with dental adhesives containing different functional monomers.

Methods: Sound dentin (SD) and post-radiotherapy irradiated dentin (ID) were tested with two adhesive systems: Clearfil SE Bond (SE, 10-MDP-based) and FL Bond II (FL, containing carboxylic and phosphonic monomers with S-PRG bioactive particles).

A case-control study of dental abnormalities and dental maturity in childhood cancer survivors.

Objective: The aim of this study was to evaluate dental abnormalities and dental maturity (DM) in the permanent dentition of childhood cancer survivors (CCSs) in comparison with that of healthy individuals.

Study Design: A retrospective, case-control study, with convenience sampling, evaluated 111 panoramic radiographs (PRs) of CCSs compared with 111 PRs of healthy individuals matched for age and gender. Dental anomalies (DAs) were associated with age of cancer diagnosis and type of antineoplastic treatment.
