The aim of this retrospective cross-sectional study was to comprehensively assess masticatory function in maxillectomy patients with functioning removable prostheses. Their general and oral profiles, the measurement values of their oral functions, including masticatory function, and the history of tumor therapy were extracted from medical charts. The correlations of masticatory function with numerical data and the effects of tumor therapy-related factors on masticatory function were evaluated. In addition, a stepwise conditional logistic regression analysis was performed to identify the potential predictive factors comprehensively. The data from 55 maxillectomy patients revealed that the median value of masticatory function (138.0 mg/dL) was higher than the threshold (100.0 mg/dL) based on the concept of oral hypofunction. Moderate correlations of masticatory function with the number of remaining teeth, the number of functioning occlusal supports, and maximum occlusal force were found, as well as a weak correlation with maximum tongue pressure. These variables also showed statistically significant coefficients ( < 0.01). No significant effect of each tumor therapy-related factor on masticatory function was detected. A logistic regression analysis identified the number of functioning occlusal supports as a significant predictive factor. These results implied the crucial interactions of masticatory function with various factors and the specificities of maxillectomy patients.

Background: Although oral diseases and frailty can be met earlier in life, there is limited information on their association across the lifespan.
Objectives: To scope for the association of oral factors with physical frailty in Greek community-dwelling adults.
Methods: Participants were over 18 years of age with ≥ 20 natural teeth, ≥ 10 occlusal contacts, and no removable dentures.

Malagasy lemurs are diverse primates that underwent adaptive radiation. While this radiation promotes modifications in cranium for niche partitioning, evolutionary constraints impose common craniofacial patterns among smaller lemurs: they are predicted to be constrained to have a shorter upper jaw and laterally-facing orbits to compensate for small masticatory muscles and accommodate relatively large orbits, regardless of niche. This study aims to elucidate how these evolutionary constraints operate during the adaptive radiation of lemurs.
View Article and Find Full Text PDFBackground: The authors conducted an umbrella systematic review to evaluate the methodological quality of existing reviews and compare the clinical and patient-centered effectiveness of single implant-retained mandibular overdentures (1i-MOs) with 2 implant-retained mandibular overdentures (2i-MOs).
Types Of Studies Reviewed: Systematic reviews with and without meta-analyses on 1i-MO and 2i-MO were included on the basis of a comprehensive literature search performed in June 2024 across MEDLINE via PubMed, Scopus, Embase, Web of Science, Cochrane Library, and System for Information on Grey Literature in Europe via OpenGrey databases. Independent reviewers performed study selection, data extraction, and analysis.

Objectives: The aim of this study is to investigate the association between masticatory muscle thickness and dysphagia in intracerebral hemorrhage (ICH) patients.
Materials & Methods: This retrospective cohort study included patients with spontaneous ICH confirmed by brain computed tomography (CT) between June 2019 and June 2024 in a university-affiliated hospital. Temporal muscle thickness (TMT) and masseter muscle thickness (MMT) were measured on the initial brain CT.

Background/aim: Neurofibromatosis type 1 (NF1) is a genetic disorder characterized by the development of multiple tumors, including plexiform neurofibromas (PNFs), which often affect the craniofacial region and cause significant functional and aesthetic impairments. This report presents long-term surgical management of a patient with hemifacial diffuse PNF, complicated by the emergence of a rapidly enlarging midfacial tumor.
Case Report: The patient was treated for hemifacial invasive diffuse plexiform neurofibroma.
