Purpose: This pilot study aimed to assess the relationship between bite force variation and dental arch and facial shape using geometric morphometrics, an advanced method of statistical analysis that provides a detailed shape analysis of a structure considering the spatial relationship of its parts.
Methods: The sample consisted of 16 German adult men and women. For each individual, maximum bite force was recorded in four positions: maximum intercuspation, protrusion, laterotrusion to the right and to the left.
Objectives: Ecogeographic variation in human nasal anatomy has historically been analyzed on skeletal morphology and interpreted in the context of climatic adaptations to respiratory air-conditioning. Only a few studies have analyzed nasal soft tissue morphology, actively involved in air-conditioning physiology.
Materials And Methods: We used in vivo computer tomographic scans of (N = 146) adult individuals from Cambodia, Chile, Russia, and Spain.
Article Synopsis
- Adult mice are used in mandibular dynamics studies because their chewing patterns are similar to humans; researchers used botulinum toxin type A (BoNTA) to induce muscle atrophy in one masseter muscle and studied its effects.
- After BoNTA treatment, there was a significant increase in atrophy-related gene expression and a reduction in muscle size, particularly in the masseter, temporalis, and medial pterygoid muscles, observed at 14 days.
- The study concluded that impairment of one masticatory muscle affects not only the treated muscle but also its agonistic counterpart, highlighting the interconnectedness of the masticatory system and the need for further clinical research.
The aim of this study was to assess the diagnostic accuracy of single photon emission tomography (SPECT) in unilateral condylar hyperplasia (UCH). To this end, 3D morphometric changes of the mandibles in one year were assessed (T0 vs. T1) and compared over SPECT results in T1, in a sample of 40 patients.

Additionally, recent research investigating the relationship between vitamin D and AIS found a relation between them. We hypothesize a negative correlation between FA and vitamin D.
