Dose‐Dependent Effects of Simulated Clinical Radiotherapy on the Structure and Properties of Root Dentine

Australian Endodontic Journal, Volume 52, Issue 1, Page 216-226, April 2026.
ABSTRACT Head and neck radiotherapy (HNRT) can expose teeth to moderate radiation doses, yet the effects on root dentine under clinically relevant conditions remain unclear. This in vitro study compared dentine subjected to 0, 30, or 50 Gy IMRT. Palatal roots from 35 maxillary molars were allocated to non‐irradiated, 30 Gy (oropharyngeal simulation ...

Atraumatic Maxillary Canine Root Repositioning as an Alternative to Orthodontic Forced Eruption: A Case Report

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Preservation of natural teeth in the anterior region is often preferred over replacement with dental implants due to functional and esthetic considerations. Although orthodontic extrusion preserves soft tissue architecture, it may not be suitable in all cases.

Association Between Residual Pericervical and Apical Dentine and Vertical Root Fracture in Endodontically Treated Molars: A Case‐Control Study

Clinical and Experimental Dental Research, Volume 12, Issue 1, February 2026.
ABSTRACT Objective Vertical root fracture (VRF) in endodontically treated molars (ETMs) is a multifactorial condition. However, the relationship between residual pericervical and apical dentine in ETMs and VRF has yet to be fully assessed. This study aimed to investigate the association between residual pericervical and apical dentine and VRF in ETMs ...

Root-originating dentinal defects: methodological aspects and clinical relevance

, 2017
It was in the 1980s when the association between root-filling procedures and dentinal microcracks was made. Nowadays, root-originating microcracks, also known as dentinal defects, are recognized as a possible precursor that is part of the longitudinal ...

Influence of Natural Pathological Alterations on the Mechanical Properties and Microstructure of Human Enamel and Dentine

Biosurface and Biotribology, Volume 12, Issue 1, January/December 2026.
ABSTRACT Dental caries represents a significant global health challenge. Accurate quantification of the mechanical properties of dental tissues is essential for understanding disease progression and guiding medical procedures. However, comprehensive comparative analyses across multiple stages of natural caries progression using a unified methodological

The effects of different nickel-titanium instruments on dentinal microcrack formations during root canal preparation

European Journal of Dentistry, 2015
ABSTRACT Objective: The aim of the present study was to investigate the incidence of dentinal microcracks caused by different preparation techniques. Materials and Methods: 120 extracted human mandibular incisor teeth were divided into five experimental groups and one control group (n = 20): Group 1: Hand preparation with balanced force ...

The Potential Association Between Betel Nut Consumption and Apical Periodontitis: A Multicenter Cross‐Sectional Study

International Journal of Dentistry, Volume 2026, Issue 1, 2026.
Introduction Chewing betel nut (BN) is a well‐established risk factor for several oral conditions, including periodontal diseases, but direct evidence linking BN chewing to pulpal and periapical (PA) pathology remains scarce. This study aimed to assess the association between BN chewing and apical periodontitis (AP).

Fracture Resistance of Roots With Si̇mulated Internal Root Resorption Followi̇ng Repair With Calcium Silicate‐Based Cements

International Journal of Dentistry, Volume 2026, Issue 1, 2026.
This study aimed to evaluate the fracture resistance of teeth with simulated internal root resorption cavities filled with calcium silicate‐based cements (CSCs). Seventy‐two extracted central incisor teeth had their crowns removed to standardize the root length to 14 mm.
