The aim of this report was to describe a rare example of sporadic intestinal-type adenocarcinoma of the major salivary glands and oral cavity. A 23-year-old female patient presented an asymptomatic, progressive-growing mass involving the floor of mouth and the left submandibular gland. Fine-needle aspiration cytology, imaging exams, and surgical specimen findings were consisted with the diagnosis of primary intestinal-type adenocarcinoma, despite its similar immunohistochemical results with colorectal adenocarcinoma.

Purpose: Teeth with poor prognosis are generally recommended to be extracted prior to head and neck radiotherapy (RT) to reduce the risk of developing osteoradionecrosis (ORN), although controversies have been reported. The present systematic review aimed to determine whether tooth extraction prior to head and neck RT may be associated with a reduced risk of developing ORN compared to dental extraction during or after RT.

Methods: The review protocol was registered in PROSPERO (CRD42021241631).

Le Fort I osteotomy is widely used in orthognathic surgery to correct maxillary deformities. However, this osteotomy may be related with the increase of alar base width. The aims of the present study were to compare two alar cinch suture after Le Fort I osteotomy and observe which type presents a better result in controlling the enlargement of the alar base after maxillary repositioning in orthognathic surgery.

Article Synopsis
  • This review examines the development and current status of oral medicine (stomatology) in Brazil, referencing the Brazilian Society of Stomatology and Oral Pathology (SOBEP) and the Federal Dental Council.
  • Oral medicine in Brazil began in 1969 with SOBEP founded in 1974, but only became officially recognized as a specialty in 1992.
  • After 50 years of growth, the field is now focusing on aligning with international trends and creating a standardized postgraduate curriculum for training oral medicine specialists in Brazil.

Article Synopsis
  • - Effective communication between clinicians and pathologists is crucial for accurate diagnoses and quality patient care, yet there is a notable lack of research specifically focusing on this topic in oral and maxillofacial pathology.
  • - A narrative review was conducted, assessing the quality of communication between clinicians and oral pathologists, revealing no existing studies on communication adequacy or necessary skills in oral diagnosis.
  • - The review suggests that improving communication could involve strategies like collaboration, clear reporting, communication skills training, and prioritizing patient-centered care, along with a call for further research to enhance practices in this field.

Article Synopsis
  • The study aimed to evaluate the safety and effectiveness of a preventive treatment called extraoral photobiomodulation (PBM) for reducing oral and oropharyngeal mucositis (OM) in patients with oral and throat cancer undergoing radiation therapy (RT).
  • Patients were randomly assigned to receive either PBM or a placebo; results showed that the PBM group had a delayed onset of OM, lower pain scores, and reduced need for pain and anti-inflammatory medications, along with improved quality of life.
  • Despite these benefits, there was no significant difference in overall survival rates between the two groups after one year, suggesting that while PBM may help with symptoms, it doesn't affect long-term cancer

The objectives of this study were to determine the effectiveness of a mucoadhesive tablet of pilocarpine, 5 mg, for the treatment of xerostomia and verify its pharmacokinetic profile. The randomized, double-blind, crossover clinical trial involved 25 older adults (60 to 80 years) with xerostomia and hyposalivation who were randomly divided into groups A and B. Once daily, for 7 days, group A used a mucoadhesive tablet containing pilocarpine, while group B used a mucoadhesive tablet without the active ingredient (first intervention).

Article Synopsis
  • Drug-induced sarcoidosis-like reaction (DISR) mimics sarcoidosis in both appearance and symptoms, typically affecting the lungs, lymph nodes, and skin.
  • An unusual case of DISR was reported in a 63-year-old woman undergoing treatment for rheumatoid arthritis with adalimumab, who developed ulcerative nodules in the oral cavity.
  • After a biopsy confirmed DISR and discontinuation of the drug, the patient's lesions fully resolved within 14 months, highlighting the need to consider DISR in oral granulomatous conditions, especially in patients on TNF-α antagonists.

Objectives: The aim of this study was to characterize the histomorphometric features of subgemmal neurogenous plaques (SNPs) to better understand their relationship to surrounding microanatomy included in the tissue biopsy samples of the tongue.

Study Design: A 12-year retrospective study on the files of 3 oral pathology centers yielded 28 SNPs. Hematoxylin and eosin-stained sections were used for histologic analysis, and immunohistochemical staining for S100 protein was performed to better characterize the neural structures.
