This paper researches the history of treatment planning for extraction of the first permanent molars and the early influence of American orthodontists on dental practice in the UK. It also discusses the development of clinical guidelines for the enforced extraction of first permanent molars to the present day.

This systematic review aimed to compare postoperative pain in endodontic treatments using PIPS Er: YAG laser-activated irrigation (LAI) versus conventional needle irrigation. An electronic search was conducted to identify randomized clinical trials (RCT) investigating postoperative pain in patients who underwent root canal treatments in permanent teeth using PIPS Er: YAG laser-activated irrigation or conventional needle irrigation. Two reviewers performed study selection, data extraction, risk of bias assessment (RoB 2.

To investigate the effect of concentrated growth factor (CGF) on the biological performance of human dental pulp stem cells (hDPSCs) under oxidative stress status induced by hydrogen peroxide (HO). The hDPSCs were isolated by using tissue block separation method from healthy permanent teeth extracted for orthodontic reason. hDPSCs surface markers CD34, CD45, CD90 and CD105 were detected by flow cytometry.

Introduction: This in vitro study assessed how shade changes induced by endodontic medicaments affect the transmission of single and multiples wavelengths of infrared light through enamel and dentin.
Methods: Eighteen extracted single-rooted permanent teeth were prepared, removing all extrinsic staining, and cementum. Tooth slices were treated for 4 weeks with UltraCal™ XS, Ledermix™, or were untreated controls.
Objective This in vitro study aimed to assess and compare the antimicrobial effectiveness of ampicillin with ceftriaxone (AC), diclofenac sodium (DS), modified triple antibiotic paste (MTAP), and calcium hydroxide (CH) against in root canal systems. Materials and methods The antimicrobial activity of the medicaments was assessed by determining the minimum inhibitory concentrations (MIC) via the agar well diffusion method. A total of 40 extracted permanent teeth underwent root canal treatment, and was introduced into the canal preparations.

Background: Depression significantly impacts an individual's thoughts, emotions, behaviors, and moods; this prevalent mental health condition affects millions globally. Traditional approaches to detecting and treating depression rely on questionnaires and personal interviews, which can be time consuming and potentially inefficient. As social media has permanently shifted the pattern of our daily communications, social media postings can offer new perspectives in understanding mental illness in individuals because they provide an unbiased exploration of their language use and behavioral patterns.
