Article Synopsis
- The study examines the complexity of teeth anatomy, especially focusing on C-shaped canals and radix entomolaris, which impact the effectiveness of root canal treatments.
- Using cone-beam computed tomography (CBCT), researchers identified the prevalence and types of these anatomical variations in a sample of 2173 teeth from a Mexican population.
- Results showed that C-shaped canals were more common in second mandibular molars, with a significant gender difference in prevalence, highlighting the importance of understanding these variations for improving endodontic treatment success rates.

Objective: The aim of this study was to investigate and compare the immunohistochemical expression of connexin 43 (Cx43) in tooth germs (TGs), ameloblastic fibromas (AFs), ameloblastic fibro-odontomas (AFOs), and conventional ameloblastomas (AMs).
Study Design: Nine TGs, 12 AFs, 12 AFOs, and 27 AMs were evaluated for Cx43 expression by immunohistochemistry.
Results: Most of the TGs expressed Cx43 in the mesenchyme (77.
[Prevalence of temporomandibular disorders according to the simplified fonseca anamnestic index in dentistry students of the juárez university of the state of durango, mexico].

June 2021
Objective: The objective was to estimate the prevalence of temporomandibular disorders (TMD), in students of the Faculty of Dentistry.
Material And Methods: This was a descriptive, observational, prospective, cross-sectional study. The study included 18 to 28-year-old students from the Faculty of Dentistry of the Universidad Juárez del Estado de Durango, México, attending the 1st to 8th semester of the 2018-A school year in whom the simplified Fonseca anamnestic index (sFAI) was applied to characterize TMD.
Peripheral giant cell granuloma (PGCG) is a relatively common benign reactive lesion of the oral cavity which can occur at any age. CTCFL/BORIS (CTCF like/Brother of the Regulator of Imprinted Sites) and CTCF (CCCTC-binding factor) are paralogous genes with an important role in the regulation of gene expression, genomic imprinting, and nuclear chromatin insulators regulation. BORIS expression promotes cell immortalization and growth while CTCF has tumor suppressor activity; the expression pattern may reflect the reverse transcription silencing of BORIS.
