The objective of this article is to highlight the importance of having a thorough knowledge about the root canal anatomy and the possible anatomical variations in maxillary second molar. This case report presents the endodontic management of the left maxillary second molar with four roots and four canals. A cone-beam computed tomography (CBCT) imaging was performed to ascertain this complex root canal anatomy. The CBCT findings revealed that the distobuccal canal and the distopalatal canal of the left maxillary second molar exhibits Vertucci Type VI root canal anatomy. This case report demonstrates the usefulness of CBCT in the understanding of complex root canal anatomy of maxillary second molar and its potential use as an endodontic diagnostic tool.

Tooth shade selection is a fundamental factor in the success of dental restorations, and visual impairment may adversely affect this process. The aim of this cross-sectional clinical study was to determine whether visual impairment influences shade selection using two methods: spectrophotometry and shade guides. : The sample consisted of 2796 maxillary and mandibular teeth, and shade selection was measured subjectively with a shade guide (VITA Classic, VITA Zahnfabrik) and objectively with a spectrophotometer (VITA Easyshade V, VITA Zahnfabrik, Bad Säckingen, Germany).

This retrospective longitudinal outcome study comparing orthodontic extraction modalities, including extraction of maxillary first or second molars, aimed to compare the three-dimensional tooth movement of maxillary canines (C), premolars (P1, P2), and molars (M1, M2) in Class II division 1 malocclusion treatment with fixed appliances. A sample of 98 patients (mean age 13.20 ± 1.

: The orthodontic management of pediatric patients with rare diseases, such as Ectodermal Dysplasia (ED) and Osteogenesis Imperfecta (OI), requires complex protocols due to dental anomalies in both the number and structure of teeth. These conditions necessitate a departure from traditional orthodontic approaches, as skeletal anchoring is often required because of these anomalies. A patient with ED, characterized by hypodontia and malformed teeth, presented with insufficient natural teeth for anchorage.

Background: Virtual surgical planning for orthognathic surgery typically relies on two methods for intraoperative plan transfer: CAD/CAM occlusal splints and patient-specific implants (PSI). While CAD/CAM splints may offer limited accuracy, particularly in the vertical dimension, PSIs are constrained by higher costs and extended preparation times. Surgical navigation has emerged as a potential alternative, but existing protocols often involve invasive registration or lack transparent evaluation.

Aim: The purpose of this study is to investigate the interchangeability of newly acquired, short-term used, and long-term used semi-adjustable articulators.
Materials And Methods: Metal analogs of partially dentate maxillary and mandibular arches were mounted on twelve semi-adjustable Stratos 300 articulators, divided into three groups based on usage over time: New, short-term used (<2 years), long-term used (>2 years) articulators. Each articulator was calibrated according to manufacturer guidelines, ensuring consistency.
