Electronic address:
Objective: This study aimed to develop 3 models based on computed tomography (CT) images of patients with craniofacial fibrous dysplasia (CFD): a radiomics model (Model Rad), a deep learning (DL) model (Model DL), and a hybrid radiomics and DL model (Model Rad+DL), and evaluate the ability of these models to distinguish between adolescents with active lesion progression and adults with stable lesion progression.
Methods: We retrospectively analyzed preoperative CT scans from 148 CFD patients treated at Shanghai Ninth People's Hospital. The images were processed using 3D-Slicer software to segment and extract regions of interest for radiomics and DL analysis.

Department of Dental and Oral Medicine and Cranio-maxillofacial and Oral Surgery, University Hospital for Conservative Dentistry and Periodontology, Medical University of Innsbruck, Innsbruck, Austria.
Introduction And Aims: We aimed to investigate the efficacy of air-polishing in restoring the original tooth colour of standardised tobacco-stained tooth specimens.
Methods: Seventy-two specimens consisting of half dentine and half enamel were daily exposed to the smoke of five cigarettes in an automated smoking chamber. Four repetitions of a 14-day smoking cycle were performed.
Correlation between measured oral health and oral health-related quality of life in people with epidermolysis bullosa: a prospective cohort study.

December 2024
Department of Cranio-Maxillofacial Surgery, University Hospital Münster, Münster, Germany.
Background: Inherited epidermolysis bullosa (EB) is a genetic disorder characterized by skin fragility and unique oral features. This prospective study aimed to analyze the correlation between oral health-related quality of life (OHRQoL) and the objectively measured oral health indices of people suffering from EB and within their subtypes.
Methods: The German version of the Oral Health Impact Profile (OHIP-14G) was employed for the assessment of OHRQoL.
Evaluation of zirconia implants in fibula and deep circumflex iliac artery flaps: a prospective 1.5-year follow-up study.

December 2024
Department of Oral and Cranio-Maxillofacial Surgery, University Hospital RWTH Aachen, Pauwelsstraße 30, Aachen, 52074, Germany.
Objectives: Follow-up results of modern zirconia implants inserted in fibula free and deep circumflex iliac artery (DCIA) flaps with fixed dentures are scarce. This study aimed to evaluate crestal bone changes and the survival rate of zirconia implants for up to 1.5 years of prospective follow-up.

The most common surgical procedure to manage the malunion of the bones is corrective osteotomy. The current gold standard for securing the bone segments after osteotomy is the use of titanium plates and allografts which have disadvantages such as possible allergic reaction, additional operations such as extraction of the graft from other sites and removal operation. The utilization of resorbable materials presents an opportunity to mitigate these drawbacks but has not yet been thoroughly researched in the literature.
