an increased overbite may be due to a skeletal or dental etiology that may influence treatment. the purpose of this study was to evaluate the skeletal and dentoalveolar features in patients with deep bite malocclusion in an iranian population and to determine the most and least effective and contributory variables causing deep bite.lateral cephalograms and study casts of normal (n=85) and deep ...

Background Thalassemia is a group of congenital disorders which is characterized by a deficient synthesis of alfa or beta globulin chains in hemoglobin molecules. Due to the problems resulting from changes in face, especially in dento-maxillary regions, such patients require special attention regarding oral health. Thus in this study, we aimed to assess the dento-maxillofacial changes in Beta-t...

A posterior cross-bite is defined as an abnormal bucco-lingual relationship between opposing molars, pre-molars or both in centric occlusion. Although it has been reported that patients with unilateral posterior cross-bite often show unique chewing patterns, the relationship between the form of cross-bite and masticatory jaw movement remains unclear in adult patients. The objective of this stud...

Bite marks can be considered as a patterned injury where identification of the causative tool will lead to the identification of the perpetrator. When patterned injuries resembling bite marks are seen on the victim or an assailant of a potential crime, all efforts must be made to carry out an immediate and proper investigation. The classical human bite mark pattern will appear as an oval or cir...

UNLABELLED This paper investigates the changes in upper and lower dental bite records that occur when the anterior teeth occlude into a three-dimensional rather than a flat object. METHODS anterior bite registrations were obtained from 20 volunteers with full and unrestored dentitions. As a three- dimensional, life-like bite target we cast a silicone replica from the impression of an actual a...

In our previous study carried out in 1994, we found 49 patients with unilateral cleft lip and palate (UCLP) among 51 patients with cleft lip and palate who visited the Department of Orthodontics, Nihon University Dental Hospital at Matsudo. In particular, patients with cross-bite (anterior cross-bite) UCLP were predominant, accounting for 21 individuals (41%). In the present study, we reviewed ...

Feeding performance is an organism's ability to capture and handle prey. Although bite force is a commonly used metric of feeding performance, other factors such as bite pressure and strike speed are also likely to affect prey capture. Therefore, this study investigated static bite force, dynamic speeds, and predator and prey forces resulting from ram strikes, as well as bite pressure of the ki...

The stomatographic system has been studied by several researchers, yet it is still unclear, weather a genetically determined facial morphology decides the strength of masticatory muscles,(1) or weather a strong musculature influences the form of the face. This formed the basis of present study to relate muscle activity with various malocclusions. Thus, 60 samples of younger age group were divid...

Many studies on the efficiency of feeding in finches concentrate on husking time in relation to average seed size and bird size. Large species are capable of eating larger seeds and are able to husk large seeds faster than smaller species. It is generally assumed that husking time is related to bite force. However, there are very few studies that investigate the relationship between husking tim...
