Background/Aim Oral epithelia demonstrate a broad spectrum of pre-cancerous, cancerous, and benign lesions. The aim of this study was to record and analyze the prevalence of various oral and intraosseous lesions, highlighting malignancies that are hard to clinically identify as such too. Materials and methods A series of 536 oral lesions were collected covering a period of 8.5 years. Epidemiological and clinico-histopathological data were stratified and analyzed retrospectively. Results According to extensive differential analysis, the male to female ratio for oral squamous cell carcinoma was estimated at 1:1, for pre-cancerous lesions at 1:2, and for lichen planus at 1:5. The prevalent diagnostic category were cysts (n = 223, 41.6%). The biological behavior of lesions differed among anatomic sites (P<0.001). Concordance between clinical suspicion of pre-cancerous or malignant lesions and histological verification was 96.4% (P<0.001). Conclusions Primary intraosseous squamous cell carcinoma, acinic cell carcinoma, clear cell myoepithelial carcinoma, aggressive osteoblastoma/parosteal osteosarcoma, and undifferentiated carcinoma raised no clinical suspicion of malignancy reflecting the importance of training in oral biopsy taking.

Background: In this study, we prepared a porous gradient scaffold with hydroxyapatite microtubules (HAMT) and chitosan (CHS) and investigated osteogenesis induced by these scaffolds.
Methods: The arrangement of wax balls in the mold can control the size and distribution of the pores of the scaffold, and form an interconnected gradient pore structure. The scaffolds were systematically evaluated and for biocompatibility, biological activity, and regulatory mechanisms.

An 80-year-old lady had a history of progressive swallowing difficulty over several years with significant weight loss, but prior investigations in several medical departments proved negative. Neurological assessment noted her complaint of impaired feeling for food in her mouth and examination showed impaired corneal reflexes and facial sensory function. Blink reflex electrodiagnostic testing was consistent with a diagnosis of facial onset sensory and motor neuronopathy (FOSMN).

Parkinson's disease (PD) is a common neurodegenerative condition that can lead to problems swallowing. Individuals living with PD may be unable to take medications orally for various reasons including acute or chronic dysphagia, non-PD related causes and being placed nil-by-mouth for elective reasons. This article outlines a five-step approach to managing an individual living with PD who is unable to take oral medication acutely.

The complicated neurological syndrome known as multiple sclerosis (MS) is typified by demyelination, inflammation, and neurodegeneration in the central nervous system (CNS). Managing this crippling illness requires an understanding of the complex interactions between neurophysiological systems, diagnostic techniques, and therapeutic methods. A complex series of processes, including immunological dysregulation, inflammation, and neurodegeneration, are involved in the pathogenesis of MS.

Background: Oral frailty in older adults can affect their eating efficiency, prolonging meal times, which can compromise food flavour.
Objective: This study explored the association between cooking methods and chewing-to-swallowing time on the basis of different oral functions in older adults.
Methods: This cross-sectional study involved 65 community-dwelling individuals aged ≥ 65 years.
