Article Abstract
The Purpose: Of the study is to reduce the risk of postoperative neuropathy of the inferior alveolar nerve by improving diagnostic methods, assessment of individual topographic and anatomical features and extraction technique of impacted teeth adjacent to the mandibular canal.
Materials And Methods: According to the CBCT examination, orthopantomography and macroscopic examination of removed third molars roots (=140) the relative position of the mandibular canal and the roots of the third molars were studied.
Results: Three variants of close mandibular canal and third molars position have been identified. In the lateral and apical nerve position, the root surface depressions were detected. With inter-radicular position fit, the mandibular canal and the nerve bundle form a «bed» in between impacted tooth roots.
Conclusion: The injury of neurovascular bundle prognosis during extraction with an interadicular mandibular position depends on roots anatomy and their convergence degree. If the interradicular distance is less than the diameter of the mandibular canal, nerve injury during tooth extraction is inevitable, in such cases coronectomy is indicated.

Objectives: This study aims to describe the cone-beam computed tomography (CBCT) characteristics of external root resorption (ERR) in second molars associated with impacted third molars.
Methods: This study analyzed 69 s molars diagnosed with ERR caused by impacted third molars in 52 patients (age range: 22-59 years; mean age = 31.2 ± 7.

Background: The treatment of mandibular angle fractures remains controversial, particularly regarding the method of fixation. The primary aim of this study was to compare surgical outcomes following treatment with 1-plate versus 2-plate fixation across two oral and maxillofacial surgery clinics. The secondary aim was to evaluate associations between patient-, trauma-, and procedure-specific factors with postoperative complications and to identify high-risk patients for secondary osteosynthesis.

No existing literature details infusion rates of remimazolam delivered by manually adjusted infusion pumps. This case report describes the administration of manually infused remimazolam to an 86-year-old man for the surgical extraction of third molars under procedural sedation.

The nerve distribution in the mandible was described in only one report which showed an increase in nerve distribution density moving from the alveolar crest toward the inferior alveolar nerve. However, no previous reports have focused on the nerve distribution density in the maxilla.

The Hippo signaling pathway, a critical regulator of cell proliferation, apoptosis, and tumor progression, is often dysregulated in NSCLC and contributes to chemo-resistance. This study investigated the potential of epigallocatechin-3-gallate (EGCG), a green tea polyphenol, to overcome OSI resistance by modulating the Hippo signaling pathway, specifically through inhibition of the YAP-1 (Yes-associated protein)-TEAD (TEA domain transcription factor)-CTGF (connective tissue growth factor) axis.
