The patient was an 84-year-old man who was referred to our hospital in mid-December 2012 for a close examination of a mass arising from the left side of the hard palate that was found by a local dentist. The initial examination revealed the presence of a 3.0-cm elastic soft, dome-shaped mass in the left hard palate. CE-CT showed a lesion of size 1.8 × 1.4 cm in the right hard palate, which extended upward and invaded the nasal cavity. The mass was a solid tumor associated with resorption of surrounding bone and expansion of the greater palatine canal. CE-MRI indicated that the mass extended upward and invaded the nasal cavity, and the mass showed hypointensity on T1-weighted images, hyperintensity on T2-weighted images, and an irregular margin with internal enhancement. Abnormal uptake of FDG on PET-CT (SUVmax = 5.2) was observed in the left hard palate. The biopsy site lesion rapidly increased in size and biopsy was performed again in January 2013 due to suspicion of a malignant tumor. The histopathological diagnosis was a suspected malignant neurogenic tumor. Therefore, the patient underwent partial maxillectomy and a split-thickness skin graft in late February 2013. No recurrence was noted 29 months after the operation.

Background: Oral cancer, particularly mucoepidermoid carcinoma (MEC), presents diagnostic challenges due to its histological diversity and rarity. This study aimed to develop machine learning (ML) models to predict survival outcomes for MEC patients and pioneer a clinically accessible prognostic tool.
Methods: Using the SEER database (2000-2020), we constructed predictive models with five ML algorithms: Random Forest Classifier (RFC), Gradient Boosting Classifier (GBC), Logistic Regression (LR), K-Nearest Neighbors (KNN), and Multilayer Perceptron (MLP).

Infantile haemangioma (IH) is the most common childhood tumour, often developing in the head and neck region. It may cause disfigurement, functional impairment, or tooth developmental issues when it is present in the oral cavity. We report a case of a 2-month-old boy referred to the paediatric dentistry team with a segmental IH involving the left periorbital, cheek, and hard palate.

Large defects in the hard palate can be difficult to treat surgically, as dehiscence is common. These defects may instead be managed with a palatal obturator, which can serve to separate the oral and nasal cavities. In this report, a 7-year-old, mixed breed dog was treated with a palatal obturator, after presenting with an acquired palatal defect following treatment of a giant cell tumor of bone in the hard palate.

Objective: The goal of this research was to examine the morphological characteristics and exact anatomical positioning of the greater palatine foramen (GPF), with reference to nearby anatomical landmarks.
Material And Method: The research was performed on dry human skulls belonging to the Bosnian and Herzegovina population, using digital vernier calipers. The study began by noting the GPF's position relative to the maxillary molars, then measuring its distance from the median palatine suture (MPS), the incisive fossa (IF), the posterior border of the hard palate (PBHP), and the posterior nasal spine (PNS).

Article Synopsis
- Mastication not only helps in breaking down food but also plays a vital role in healing oral tissue by balancing damage and repair mechanisms.
- Research showed that mice on a soft food diet healed more slowly from oral wounds compared to those on a hard food diet, suggesting that masticatory stress is important for tissue repair.
- The study found that reduced masticatory stress led to lower expression of key genes involved in healing and macrophage activity, indicating the significance of physical stimulation in enhancing immune responses and wound healing in oral tissues.
