Purpose: Oral sensorimotor function performs an important role in mastication. This study investigated the influence of wearing experimental palatal plates on masticatory efficiency and oral stereognostic ability (OSA), and the relationship between these two functions.
Methods: Fifteen young adults with healthy dentitions (mean age, 26.4 years) participated in this study. Masticatory efficiency was determined using a sieving method and OSA test was conducted by 12 shaped forms. These tests were performed in random order under three different conditions: control (without experimental plate), Plate-A (a horseshoe-shaped and 10mm in width from the gingival cuff) and Plate-B (the entire palate was covered). The thickness of experimental plate was 1.5mm. The statistical significance level was set at P<0.05.
Results: Masticatory efficiency was significantly reduced with Plate-B, but not with Plate-A, compared with control. OSA scores were not significantly influenced by the presence of either plate. A significant positive correlation existed between masticatory efficiency and OSA score in control and with Plate-A, but not with Plate-B.
Conclusion: We suggest that wearing Plate-A had no influence on masticatory efficiency and did not disturb oral sensorimotor control of the masticatory mechanism, while wearing Plate-B reduced masticatory efficiency and might have an effect on the relationship between OSA and mastication in young dentate adults.

Background: Arthrocentesis is effective at reducing pain and improving function in patients with temporomandibular joint intra-articular pain and dysfunction (IPD). It remains unclear if it is equally effective in patients with systemic polyarthritis (SPA) and IPD.
Purpose: The purpose of this study was to compare changes in pain and function following arthrocentesis for IPD in subjects with and without SPA.

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.

: A critical review of the literature demonstrates that masticatory apparatus with an artificial oral environment is of interest in the fields including (i) dental science; (ii) food science; (iii) the pharmaceutical industries for drug release. However, apparatus that closely mimics human chewing and oral conditions has yet to be realised. This study investigates the vital role of dental morphology and form-function connections using two-bite test parameters for effective drug release from medicated chewing gum (MCG) and compares them to human chewing efficiency with the aid of a humanoid chewing robot and a bionics product lifecycle management (PLM) framework with built-in reverse biomimetics-both developed by the first author.

Purpose: To explore the influence of alveolar process expansion, guided bone regeneration (GBR) and bone grafting for simultaneous dental implantation therapy on bone resorption volume, retention and masticatory function in patients with severe deficiency of alveolar bone horizontal width.
Methods: Eighty patients with severely insufficient alveolar bone width who received dental implantation therapy in Hangzhou Stomatology Hospital were selected from January 2021 to January 2023. Totally 40 patients (55 teeth) who received alveolar process expansion combined with GBR bone grafting were included in the experimental group, while 40 patients (51 teeth) with traditional alveolar bone splitting were enrolled as the control group.

Aim: The present study aims to assess the efficacy of elastic occlusal splints on mobile posterior teeth in patients with stage III or IV periodontitis during Steps 1 and 2 of periodontal therapy.
Materials And Methods: Thirty-eight periodontitis patients, each with at least one mobile maxillary posterior tooth (mobility degree II or III), were randomly assigned to either the Splint group (n = 19), which received maxillary elastic occlusal splints, or the Control group (n = 19), without splints treatment. All patients received Steps 1 and 2 of periodontal therapy.
