The patient presented to the department of stomatology with a 2-month history of gingival swelling and pain on the right upper posterior teeth...

BACKGROUND: The submental artery perforator flap (SMAPF) is an alternative to reconstruct oral and maxillofacial defects secondary to oral cancers. However, vascular anomalies or surgical damage often lead to vascular crises or harvest failure. Our clinical findings suggest that the vena comitans of the facial artery (cFA) very commonly exist. This study aimed to investigate the reliability of the cFA as a sole venous reflux route for the SMAPF. METHOD: The patients were from the Department of Oral and Maxillofacial Surgery, Hospital of Stomatology, Jilin University...

BACKGROUND: Cleft lip and palate is one of the most common oral and maxillofacial deformities associated with a variety of functional disorders. Cleft palate speech disorder (CPSD) occurs the most frequently and manifests a series of characteristic speech features, which are called cleft speech characteristics. Some scholars believe that children with CPSD and poor speech outcomes may also have weaknesses in speech input processing ability, but evidence is still lacking so far. AIMS: (1) To explore whether children with CPSD and speech output disorders also have defects in speech input processing abilities; (2) to explore the correlation between speech input and output processing abilities...

BACKGROUND: Changes in healthy and inflamed pulp on periapical radiographs are traditionally so subtle that they may be imperceptible to human experts, limiting its potential use as an adjunct clinical diagnostic feature. AIM: This study aimed to investigate the feasibility of an image-analysis technique based on the convolutional neural network (CNN) to detect irreversible pulpitis in primary molars on periapical radiographs (PRs).

Oral cavity metastasis from renal cell carcinoma is rare with poor prognosis. Recently immune checkpoint inhibitors (ICIs) have shown promising outcomes in the treatment of advanced RCC. Herein, we report a case of palatal lesion mimicking vascular tumor in a 60-year-old woman with locally advanced kidney cancer (T3aN0M0). She underwent an excisional biopsy, and histopathological examinations revealed an oral metastasis from clear cell renal cell carcinoma (ccRCC). The patient was treated with a combination of two ICIs with nivolumab, a programmed death 1 (PD-1), and ipilimumab, a cytotoxic T-lymphocyte-associated antigen 4 (CTLA4)...

OBJECTIVE: Resection of tumors of oral cavity usually causes short- or long-term sequelae such as chewing, speech and swallowing impairment. To preserve this function it is necessary to maintain the lining of the oral cavity, the mobility and sensitivity of the tongue. Reconstructive options for oral mucosal defects resulting from tumor resection included primary closure, mucosal and skin grafts, pedicle and microvascular free flaps, and dermal matrix. STUDY DESIGN: Retrospective study on patients undergoing reconstruction of intraoral defects, after removal of T1, T2 malignant tumors, by placement of bilayer dermal matrix...

This study aimed to assess the diagnostic performance of a machine learning approach that utilized radiomic features extracted from Cone Beam Computer Tomography (CBCT) images and inflammatory biomarkers for distinguishing between Dentigerous Cysts (DCs), Odontogenic Keratocysts (OKCs), and Unicystic Ameloblastomas (UAs). This retrospective study involves 103 patients who underwent jaw lesion surgery in the Maxillofacial Surgery Unit of Federico II University Of Naples between January 2018 and January 2023...

INTRODUCTION: The extent of surgical resection for tongue tumors is determined by tumor size, potentially affecting oral function and quality of life (QoL). However, the relationship between oral dysfunction and QoL decline due to glossectomy extent remains unexplored. Therefore, these correlations and their predictive value for postoperative QoL decline were elucidated. METHODS: Patients treated for tongue cancer at our hospital between 2018 and 2022 were categorized by partial, hemi, or subtotal/total glossectomy...

OBJECTIVE: The two commonly used diagnostic methods for taurodontism are susceptible to aging changes, mastication wear and other factors. Therefore, this study proposed an improved diagnostic method for taurodontism, and compared it with the previous two methods as a supplement for taurodontism diagnosis. METHODS: The included patients were aged 10-89 years and admitted to the Department of Stomatology of Hebei Eye Hospital from June 1, 2022 to May 31, 2023. Eighty cone-beam computed tomography images were divided equally into 4 groups: 10-29, 30-49, 50-69, and 70-89 years old...

INTRODUCTION: Craniofacial microsomia (CFM) and camel-hump condylo-mandibular dysplasia (CMD) are developmental disorders affecting the mandible that share common clinical features.
