Objective: The influence of pulp status on orthodontically induced root resorption has attracted attention. The purpose of this study was to compare orthodontically induced root resorption in endodontically treated teeth and their contralateral vital teeth in a split-mouth design.
Methods: The sample included 173 patients who had at least one endodontically treated tooth, and their vital contralateral teeth served as the control group before the completion of orthodontic treatment. Apical root resorption measurements were performed by the comparison of digital panoramic X-ray images obtained at the beginning and at the end of the orthodontic treatment. Kruskal-Wallis, Mann-Whitney U, and Wilcoxon tests were used for statistical analysis.
Results: There was no statistically significant difference in apical root resorption between the endodontically treated teeth and the contralateral teeth (p>0.05). Sex and tooth type had no effect on apical root resorption both in the endodontically treated teeth and the contralateral vital teeth (p>0.05). Orthodontic treatment with extraction caused more apical root resorption in the vital teeth than in the endodontically treated teeth (p<0.05). The quality of the endodontic treatment had no significant influence on apical root resorption (p>0.05).
Conclusion: Endodontic treatment does not produce greater apical root resorption compared with the vital teeth.

Purpose: The aim of this study was to examine the effect of methylphenidate, prescribed for individuals with attention deficit hyperactivity disorder (ADHD), on orthodontic tooth movement (OTM) and root resorption.
Methods: In all, 30 rats were divided into (1) control (C), (2) constant (MCD), and (3) increasing dose of methylphenidate (MID) groups and 2 subgroups for each of them (nonorthodontic (30 days)/orthodontic (44 days)). After receiving saline or methylphenidate for 30 days, rats in the nonorthodontic groups were euthanized (n = 5/group).

Department of Periodontology, Dental Student's Research Committee, Isfahan University of Medical Sciences, Isfahan, Iran.
Background: This systematic review and meta-analysis aimed to assess the efficacy of autologous platelet concentrate (APCs) in comparison with coronally-advanced flap alone or in combination with connective tissue graft or other biomaterials or bioactive agents for root coverage (RC) of Miller's Class I and II gingival recession defects by measuring the keratinized mucosa width (KMW).
Materials And Methods: This systematic review and meta-analysis was conducted in accordance with the preferred reporting items for systematic reviews and meta-analysis guidelines. An electronic search of the literature was conducted in PubMed, EMBASE, Scopus, Cochrane, Web of Science, Magiran, Scientific Information Database, and Irandoc for randomized clinical trials (RCTs) that used APCs for RC in their intervention group.

Background: The pre-extraction overbuilding procedure was designed aiming to mitigate buccal bone resorption following tooth extraction. The objective of this study was to compare the efficacy of pre-extraction and juxta-extraction buccal overbuilding treatments in preserving buccal bone volume following tooth extraction.
Material And Methods: At the test sites (pre-extraction sites), an alveolar crest overbuilding was performed on the buccal aspect of the distal root of the fourth premolar using a xenograft covered with a collagen membrane.

Objective Permanent teeth roots undergo resorption under pathologic conditions such as trauma, orthodontic treatment, pulpal infections, periodontitis, and periodontal therapy. The present study aimed to determine the prevalence of external root resorption (ERR) in patients with periodontitis as seen in orthopantomography (OPGs). Methodology This single-center, retrospective, cross-sectional radiographic study was conducted from January 2021 to December 2022, including 656 orthopantomographs (OPGs) from patients with periodontitis.
