Article Abstract
Purpose: To assess function by identifying changes in swallowing and masticatory performance in maxillary obturator prosthesis wearers.
Materials And Methods: Sixty subjects were recruited for the study, of which 20 were obturator wearers, 20 were completely dentulous and 20 had removable partial/complete dentures with similar Eichner's Index. Swallowing ability was evaluated with and without obturator using the "Water Drinking Test"; Masticatory performance was evaluated with the Sieve test; and maximum occlusal force was recorded with the help of a digital bite sensor. The data was analyzed using the Statistical Package for Social Science version 15.0 with a confidence level at 95%.
Results: Profile, behavior of drinking and time taken to drink were significantly improved (P<.001) in subjects after wearing obturator. Masticatory performance was not significantly different (P=.252) in obturator wearer when compared with dentulous or removable partial/complete denture wearer, but significantly (P<.001) high inter group difference in maximum occlusal force existed. Correlation between masticatory performance and maximum occlusal force was not significant (P=.124).
Conclusion: Swallowing ability was significantly improved after wearing obturator but masticatory performance was not significantly different from those having similar occlusal support zone in their dentition.

Department of Prosthodontics, Dental School, National and Kapodistrian University of Athens, Athens, Greece.
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.
Background: 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.

Objective: To compare the results of surface electromyography in patients with functional disorders of the masticatory muscles at all stages of complex therapy and to demonstrate the need for the introduction of a generally accepted comprehensive approach to the examination and treatment of patients with this pathology.
Material And Methods: EMG studies were conducted in 127 patients of both sexes aged 35 to 54 years, who were divided into 2 groups. The first (control group) consisted of 20 patients without signs of functional disorders in the masticatory muscles.

Masticatory dysfunction is a risk factor for Alzheimer 's disease (AD), likely due to the trigeminal influences on the Locus Coeruleus (LC), a structure implicated in neurodegenerative processes and whose activity level is reflected by pupil size. Chewing activity acutely stimulates cognitive performance by increasing LC activation during task, as reflected by an increased pupil dilatation (mydriasis). The presence of a trigeminal sensorimotor imbalance is associated to an asymmetry in LC activity (reflected by an asymmetry in pupil size) and is detrimental for performance.

Objectives: This study aimed to investigate the effects of rapid maxillary expansion using a Hyrax-type appliance (RME-Hyrax) with anterior traction on the maxillary arch during mixed dentition and its clinical significance, focusing on changes in arch dimensions, occlusal stability, and masticatory function.
Materials And Methods: Forty-two patients with transverse maxillary deficiency were treated with RME-Hyrax, while an untreated control group of 40 received no treatment. Pre- and post-treatment dental casts were analyzed using a 3D scanner.
