Impacts of platelet‐rich fibrin and platelet‐rich plasma on primary osteoblast adhesion onto titanium implants in a bisphosphonate in‐vitro model
Abstract Background Osteoblast adhesion is a crucial step in osseointegration of dental implants and can be influenced by modification of implant surface or the addition of bioactive agents. Bisphosphonates affect bone turnover, attenuating bone healing in implants patients. PRP and PRF are sources of growth factors involved in osteoblast adhesion, improving subsequent bone healing. The aim of the study was to investigate the impacts of PRP and PRF on adhesion of bisphosphonate‐pretreated osteoblasts...

Role of the arecoline/YAP1/BMP4 pathway in promoting endothelial−mesenchymal transition in oral submucous fibrosis
Abstract Background Oral submucous fibrosis (OSF) is a potentially malignant lesion characterized by epithelial–mesenchymal transition (EMT). Bone morphogenetic protein 4 (BMP4) promotes EMT in fibrotic diseases, but the underlying mechanisms and its potential role in OSF are unclear. This study investigates whether BMP4 plays a role in the pathogenesis of OSF and explores the underlying mechanisms. Methods The expression of BMP4 and the EMT proteins E‐cadherin and vimentin was investigated...

RP11‐284F21.9 promotes oral squamous cell carcinoma development via the miR‐383‐5p/MAL2 axis
Abstract Background Increasing evidence suggests that dysregulated long non‐coding RNAs (lncRNAs) are involved in tumorigenesis and progression. RP11‐284F21.9, one of the temporally expressed S‐phase lncRNAs in cancer cells, was recently identified by nascent RNA capture sequencing. Methods Cal‐27, Tca8113, SCC‐9, HB56, and oral squamous cell carcinoma (OSCC) tissues were used in the experiment.

Sandwich technique for the surgical management of oral submucous fibrosis
The standard treatment of oral submucous fibrosis is fibrotomy together with a coronoidotomy or coronoidectomy, or both, and the extraction of all third molars. To achieve predictable mouth opening without recurrence, reconstruction with a buccal fat pad or nasolabial flap are most commonly used, but both techniques have limitations.

Systematic review of oral and craniofacial findings in patients with Fabry disease or Pompe disease
Fabry disease and Pompe disease are rare lysosomal storage disorders that belong to a heterogeneous group of more than 200 distinct inborn metabolic diseases. Mutations followed by loss of function of enzymes or transporters that are localised in the acidic environment of the lysosome may result in degradation of many substrates, such as glycosaminoglycans, glycosphingolipids, glycogen, cholesterol, oligosaccharides, glycoproteins, and peptides, or the excretion of the products degraded by the lysosome.

Retromandibular transparotid approach compared with transmasseteric anterior parotid approach for the management of fractures of the mandibular condylar process: a prospective randomised study
Fractures of the mandibular condyle lead to displacement of the condyle and loss of the height of the ramus. A retromandibular approach is the most commonly used for open reduction and internal fixation (ORIF) of such fractures. We aimed to compare the complications associated with a retromandibular transparotid approach with a retromandibular transmasseteric anterior parotid (TMAP) approach for their management. Thirty patients were randomly selected into two groups (15 in each): Group A comprised...

Metastasis of carcinoma ex pleomorphic adenoma to the brain without previous metastasis to the lungs or bones: a case report
Carcinoma ex pleomorphic adenoma is a rare type of cancer of the salivary gland that involves the malignant transformation of a primary or recurrent pleomorphic adenoma, which often metastasises to the lungs or bones, or both. To the best of our knowledge, however, nobody has reported a distant metastasis of this lesion to the brain without such previous metastasis. We report a case in a 64-year-old man.

Use of a Foley catheter in the drainage of deep space neck infections
Deep space infections in the oral and maxillofacial region occur when an infectious process spreads through the potential spaces bounded by the deep cervical fascia in the head and neck. These infections are usually odontogenic in origin, but can be the result of trauma, immunosuppression, or disease.1 Incision and drainage are still the treatments of choice, with management of the source if possible, and drains are often left in place afterwards.
