Analysis of the Internal Anatomy of Distal Root Canals of Mandibular Molars: A Micro‐Computed Tomography Study

X-Ray Spectrometry, Volume 55, Issue 5, Page 712-720, September/October 2026.
ABSTRACT Detailed knowledge of the internal anatomy of the root canal system and its variations is essential for selecting appropriate endodontic treatment protocols. Micro‐computed tomography (micro‐CT) allows for nondestructive, high‐resolution three‐dimensional (3D) analysis of extracted teeth, enabling precise evaluation of root canal morphology ...

Characterisation of the Mesial Root and Middle Mesial Canal Morphology in Mandibular First Molars: An Ex Vivo Micro‐CT Study

Australian Endodontic Journal, Volume 52, Issue 2, Page 364-380, August 2026.
ABSTRACT This ex vivo study characterised the mesial root morphology of mandibular first molars with a middle mesial canal (MMC) using micro‐CT. Among 469 scanned molars, 42 (8.96%) presented an MMC. Morphological parameters analysed included canal configuration, chamber orifice features, dentine thickness, isthmus type, and aspect ratio.

A Stepwise Approach to Managing Bilateral Maxillary Sinus Tracts: A Case Report

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT This case report describes a rare presentation of bilateral intraoral sinus tracts of odontogenic origin associated with a maxillary right first molar (Universal #3). A key diagnostic challenge was differentiating an endodontic infection from vertical root fracture (VRF) in a previously treated tooth; no J‐shaped probing defect was detected ...

Variations of Root Canal Morphology in Permanent Anterior and Posterior Teeth Found in Indian Population: A Narrative Review

Indian Journal of Dental Sciences
Atypical tooth or root anatomy should be identified as a variation when it is observed frequently in a particular community or ethnic group. The root canal morphology depends on demographic factors such as age, gender, and ethnicity.

Effect of Seed Position on Parental Plant of Kroenleinia grusonii (Hildm.) Lodé. and Echinocactus platyacanthus Link & Otto on Seed Germination at High Temperatures

Plant Species Biology, Volume 41, Issue 4, July 2026.
Kroenleinia grusonii and Echinocactus platyacanthus are native and endemic to Mexico, both have ecological and economic importance and are endangered species. The position in which seeds develop on the parental plant can have effects on physical and physiological characteristics. Seed position on parental plant of Kroenleinia spp. and Echinocactus spp.
