Maxillary first molar can have a mesio-buccal-2 (MB2) orifice located palatally, but adjacent to the mesio buccal orifice. An awareness and understanding of this root canal morphology can contribute to the successful outcome of root canal treatment. This report discusses endodontic treatment of a maxillary first molar with unusual location of second mesio buccal orifice. Conventional diagnostic aids such as radiographs play an important role in assessment of complex root canal morphologies. These modalities, however, do not provide detailed information of the complexity as a result of their inherent limitations. This article discusses the variations in the orifice location and the use of latest adjuncts in successfully diagnosing and negotiating them.

To date, pagetoid spread-the proliferation of pagetoid cells in intraepidermal lesions, as observed in secondary extramammary Paget's disease-has not been reported in squamous epithelium derived from the extension of head and neck carcinomas. Herein, we report a case of pagetoid squamous cell proliferation associated with a primary intraosseous carcinoma (PIOC) arising in the periapical lesion of the maxilla, a finding not reported previously. A 60-year-old man presented with prostate adenocarcinoma and bilateral pubic bone, ilium bone, and sacral bone metastases.

Background: Gingival recession defects (GRDs) pose functional and esthetic concerns and may be associated with unfavorable tooth positions. Surgically facilitated orthodontic treatment (SFOT) with clear aligners can be a valuable option for adults with severe malocclusion and GRDs.
Methods: A 28-year-old male presented with severe dental crowding, Class III dental malocclusion, localized tooth crossbites, and tapered maxillary arch.

Children are particularly vulnerable to fatalities from fire incidents, and the crucial role of dentition in the identification processes is well known. Despite this, research on burned deciduous teeth is lacking, often assuming similarities with burned permanent teeth, disregarding their morphological and chemical distinctions. This goal of this study was to investigate the effect of burning on deciduous teeth, focusing on post-burning tooth color assessment.

Background: Long-term durability of a restoration relies on the marginal integrity and its ability to withstand the occlusal forces. Fiber-reinforced composites (FRCs) exhibited superior properties in terms of fracture toughness, flexural strength, and wear resistance.
Aim: The aim of this study was to assess and compare marginal adaptation and microtensile bond strength (µTBS) of posterior FRCs comparing with a condensable composite.

The aim of this study was to investigate the effect of thermogenic supplementation on the bone tissue of rats subjected to orthodontic movement. A total of 38 male Wistar rats underwent orthodontic movement of the left permanent maxillary first molars for 21 days. The rats were assigned to three groups: Control group: water; Thermogenic 1: C4 Beta Pump thermogenic; or Thermogenic 2: PRE-HD/Pre-workout.
