Dentistry

Periapical pathosis in periapical radiographs must be properly diagnosed for the success of endodontic treatment but is often muddled by 2D imaging limitations and subjective interpretation. Artificial intelligence (AI) offers a solution, but whether the diagnostic granularity of AI versus human clinicians in everyday clinical practice has been adequately explored remains to be addressed. The purpose of this study was to evaluate the diagnostic accuracy of ChatGPT-5 in detecting periapical radiographic abnormalities compared with the three-expert consensus reference standard. Methods: In this diagnostic accuracy retrospective study, 270 periapical radiographs were independently read by a large language model (ChatGPT-5) and a …

Endodontic Access Through Zirconia Crowns: A Comparative Evaluation Of 3d Guided Versus Free-Handed Techniques, Maryam Alrughaib

Theses and Dissertations

Objective:

Accessing canals through full-coverage zirconia crowns is challenging and may increase the risk of misdirection, excessive dentin removal, and prolonged chair time. Guided endodontic access has been proposed to improve efficiency and precision. This study compared the accuracy and time efficiency of guided versus free-hand endodontic access through zirconia restorations. The hypothesis was that guided access would enhance canal localization precision and significantly reduce access time.

Methods:

Thirty-two extracted maxillary premolars were restored with 1-mm–reduced monolithic zirconia crowns (3Y-TZP, Katana HTML, Kuraray, Japan) and mounted in Modupro models. Teeth were assigned to two groups (n = 16 each): guided …

Aesthetic Rehabilitation Of A Complex Crown-Root Fracture By Fragment Reattachment With A Fiber-Reinforced Post: A Case Report, Sarra Saidi, Meriem Fejjeri, Mahdi Tlili, Sabra Jaafoura, Nadia Frih

International Arab Journal of Dentistry

Complex crown-root fractures are characterized by the involvement of both crown and root with pulp exposure. They pose aesthetic, functional, and psychological problems for the patient. Furthermore, they can pose technical difficulties for the practitioner. The purpose of this case report is to describe the management of a complex crown-root fracture of the right upper central incisor with subgingival limit by reattaching the tooth fragment with fiber-reinforced post. We considered a coronal elongation (gingivectomy and osteoplasty) to recreate the biological space and to expose the limit of the fracture line to guarantee the quality of the bond.

Sinus Tract Vs. Fistula: There Is A Difference, Mea Weinberg Dmd, Msd, Rph, Stuart Segelnick Dds, Ms, Christine Chu Dds, Asgeir Sigurdsson Dds, Ms

The New York State Dental Journal

Analysis Of Periapical Biopsies Submitted For Histopathological Evaluation: A Retrospective Study, Abdullah I. Alqaied

Master's Theses

Apical periodontitis is the most common pathological process in the periapical region. Disciplined clinical and radiographic evaluations and appropriate diagnostic tests can detect lesions related to apical periodontitis. Aside from this, lesions mimicking pulp-related pathology but unrelated to pulpal infection and necrosis are occasionally discovered in the periapical region. The objective of this study was two-fold: (1) to determine the prevalence of diverse periapically located pathological entities, and (2) to apply that information to evaluate the rationale for routine submission of surgically obtained tissue for histological examination and diagnosis. Methods: A 5-year retrospective analysis of pathology reports from the UCONN …
