Subcutaneous facial emphysema is a well-known consequence of oral and maxillofacial traumatic injury. In some rare cases, the subcutaneous air collection could spread through the retropharyngeal and paralatero-cervical spaces, reaching the mediastinum. A 55-year-old man was presented to the emergency room after a blast injury caused by a blown truck tire while trying to change tires. The chest radiograph demonstrated suspected pneumomediastinum or pneumothorax. A computed tomography scan of the neck and thorax revealed widespread surgical emphysema along the thoracic wall, extending through the mediastinum. The patient was monitored in the Thoracic Surgery Department after surgery and managed with conservative methods. He had no complications on clinical follow-up following hospital discharge. The development of pneumomediastinum after oral or maxillofacial trauma is rare. Nevertheless, given the mortal complications that may develop, clinicians should keep pneumomediastinum in mind in the differential diagnosis.

Objective: This study compared the fracture load, stress distribution, and survival probability under cyclic loading of extensively restored teeth treated with multisonic irrigation with those treated with conventional instrumentation, with or without a post.
Methods: Mesial-occlusal-distal cavities were prepared in 30 human mandibular premolars. The teeth were randomly divided into 3 groups of 10 based on the endodontic and restorative procedures: (1) Root canal treatment (RCT) followed by resin composite restoration (control group), (2) RCT followed by a glass fiber post restoration (conventional group), and (3) minimal instrumentation plus multisonic irrigation followed by resin composite restoration (GW group).

Objective: To evaluate the efficacy and safety of transoral surgical management for complex submandibular gland (SMG) stones.
Study Design: A retrospective cohort study of 240 patients treated for sialolithiasis between 2015 and 2018, focusing on 57 cases of SMG stones that underwent stone removal procedures. Treatment methods, success rates, and complications were analyzed using Kaplan-Meier analysis, Cox proportional hazards regression, and multiple logistic regression.

Background: Cervical lymph node metastasis (LNM) is a well-established poor prognosticator of oral squamous cell carcinoma (OSCC), in which occult metastasis is a subtype that makes prediction challenging. Here, we developed and validated a deep learning (DL) model using magnetic resonance imaging (MRI) for the identification of LNM in OSCC patients.
Methods: This retrospective diagnostic study developed a three-stage DL model by 45,664 preoperative MRI images from 723 patients in 10 Chinese hospitals between January 2015 and October 2020.

Background: Despite assumptions that insurance coverage would boost oral healthcare utilization in Nigeria, there is insufficient evidence supporting this claim. This study investigates the associations between residential location, awareness of the oral health insurance scheme, history of dental service utilization, and acceptance of oral health insurance among individuals benefiting from the Ilera Eko Scheme; a scheme that integrates preventive and curative oral health care into the state health insurance scheme.
Methods: A cross-sectional survey was conducted from July to November 2023 recruiting from a database of 1520 enrollees aged of 18 and 72-years-old who had been on the scheme for at least three months.
