This study aimed to evaluate the performance of ChatGPT 3 and ChatGPT 4 on self-assessment questions for dentistry, through the Swiss Federal Licensing Examination in Dental Medicine (SFLEDM), and allergy and clinical immunology, through the European Examination in Allergy and Clinical Immunology (EEAACI).

Endodontic and restorative management of an adult with avulsion of multiple teeth: A case report with 5 years and 9 months of follow-up.

Simultaneous avulsion of four or more teeth is a rare event. This case report examines the dental care given to an adult who, during a bicycle accident, experienced the avulsion of a mandibular incisor as well as all of his maxillary incisors. In the immediate aftermath of the accident, four out of the five incisors were located, promptly collected, and stored in a tooth rescue box, all within a 20-min window.

Deep Margin Elevation: Next-Level Adhesive Dentistry to Avoid Surgical Crown Lengthening.

Surgical crown lengthening (SCL) is the treatment of choice to ensure healthy tissues when subgingival tooth defects encroach on the biologic width.1 However, restorative techniques employing adhesive dentistry may provide viable alternatives to or complement SCL in select cases without the repercussions of surgical bone removal and open interproximal spaces. One such clinical technique, deep margin elevation (DME), employs a direct restoration to relocate the cervical margin of small subgingival defects of posterior teeth supragingivally.

Identifying and Avoiding Risk of Bias in Caries Diagnostic Studies.

Caries diagnostic studies differ with respect to their design, included patients/tooth samples, use of diagnostic and reference methods, calibration, blinding and data reporting. Such heterogeneity makes comparisons between studies difficult and could represent a substantial risk of bias (RoB) when it is not identified. Therefore, the present report aims to describe the development and background of a RoB assessment tool for caries diagnostic studies.
