The bite force of the piranha (Serrasalmidae) has drawn considerable attention due to its ability to effectively capture and masticate prey. Herein, we analyze theoretical anterior bite forces using a lever approach and compare them to in-vivo maximum bite forces. We provide a mechanics analysis that explains the scaling allometry of the bite force (F) with the length of the fish (l), Fαl.

Background: Bite force is one of the important factors that determine the chewing efficiency of molars. This study aimed to investigate the relationship of the maximum bite force (MBF) to the 3-dimensional (3D) arrangement of the first mandibular molars in Angle's class I healthy adults using a digital protocol.

Material And Methods: Subjects were 33 adults (16 males and 17 females) aged 18-25, with Angle's class I occlusions and healthy dentitions.

Comparative finite element analysis involves standardising aspects of models to test equivalent loading scenarios across species. However, regarding feeding biomechanics of the vertebrate skull, what is considered "equivalent" can depend on the hypothesis. Using 13 diversely-shaped skulls of marsupial bettongs and potoroos (Potoroidae), we demonstrate that scaling muscle forces to standardise specific aspects of biting mechanics can produce clearly opposing comparisons of stress or strain that are differentially suited to address specific kinds of hypotheses.

Background: Smoking is presumed to cause a decline in masticatory performance by worsening the intraoral environment in various ways. However, no longitudinal study has examined the relationship between smoking and masticatory performance.

Objectives: To clarify how smoking affects future decline in masticatory performance through a 5-year follow-up study of a general urban population.

Occlusal tactile acuity (OTA) and bite force are essential components of the sensorimotor control of oral behaviors. While these variables have been studied independently, it has not yet been revealed whether compressive force impacts the occlusal perception mediated by the mechanoreceptive afferents in the periodontal ligament. The present study examined the effect of repetition and maximum bite force on OTA by testing nine aluminum foils of different thicknesses together with a sham test with no foil, three times each, in randomized order in 36 healthy individuals.

Interchangeability of Contemporary Semi-adjustable Articulators Used Over Time: An Study.

Department of Preventive and Restorative Dentistry, School of Dental Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, United States.

Aim: The purpose of this study is to investigate the interchangeability of newly acquired, short-term used, and long-term used semi-adjustable articulators.

Materials And Methods: Metal analogs of partially dentate maxillary and mandibular arches were mounted on twelve semi-adjustable Stratos 300 articulators, divided into three groups based on usage over time: New, short-term used (<2 years), long-term used (>2 years) articulators. Each articulator was calibrated according to manufacturer guidelines, ensuring consistency.
