Article Abstract
Unlabelled: Teeth extractions before or after radiotherapy (RT) could be procedures at high risk for osteoradionecrosis (ORN) onset. This systematic review was performed to investigate the ORN incidence following teeth extractions during and after RT for head and neck (H&N) cancer and to evaluate any other possible risk factor.
Methods: This systematic review was conducted according to PRISMA protocol, and the PROSPERO registration number was CRD42018079986. An electronic search was performed on the following search engines: PubMed, Scopus, and Web of Science. A cumulative meta-analysis was performed.
Results: Two thousand two hundred and eighty-one records were screened, and nine were finally included. This systematic review revealed an ORN incidence of 5.8% (41 patients out of 462, 95% CI = 2.3-9.4); 3 ORN developed in the maxilla. No other clinical risk factors were detected.
Conclusion: Post-RT teeth extractions represent a major risk factor for ORN development, especially in the mandible, with a diminishing trend in the last years. Further research on other possible risk factors might improve this evidence.

Three-dimensional evaluation of age-related changes in root canal curvature and dentin thickness in mandibular first molars using micro-computed tomography.

This study aimed to investigate the age-related alterations in mesial roots of mandibular first molar in terms of root canal curvature values, dentin thickness, interorifice distance, deviation from apical foramen, and location of apical foramen using a three-dimensional curvature measurement method and micro-computed tomography (micro-CT). Forty-five mesial roots of mandibular first molars from three age groups (Group 1: ≤ 30 years, Group 2: 31-59 years, Group 3: ≥ 60 years) were scanned using micro-CT. The central axis of each mesiobuccal and mesiolingual canal was analyzed using cubic B-spline curves to calculate canal curvature.

Introduction: Dental health and overall well-being are greatly impacted by temporomandibular disorders (TMDs), which encompass a spectrum of illnesses that impact the temporomandibular joint and its surrounding structures. The use of dental prostheses, including complete and partial dentures, is common among individuals with missing teeth. However, the association between denture types and the prevalence of TMD remains a subject of interest and concern in the field of oral health.

Purpose: To present a novel digital workflow (the Columbus Digital Bridge Protocol) for immediately loaded full-arch rehabilitations, integrating digital technologies throughout diagnostic, surgical and prosthetic phases, with a focus on the application of intraoral photogrammetry scanning.
Materials And Methods: The workflow presented in this article, successfully implemented in 14 patients, includes standardised clinical steps: digital diagnostic planning through matching of facial scans and CBCT data, surgical placement of four implants following tooth extraction, immediate post-surgical intraoral photogrammetry scanning using a three-step procedure (i.e.
