OBJECTIVE The maintenance of normal conditions of the masticatory function is determinant for the correct growth and development of its structures. Thus, the aims of this study were to evaluate the influence of sucking habits on the presence of crossbite and its relationship with maximal bite force, facial morphology and body variables in 67 children of both genders (3.5-7 years) with primary o...

Bite forces of 39 species from six families of New World bats with a variety of diets are quantified with a force meter under field conditions. Using regression approaches we search for a model that is a good morphological predictor of these bite forces. Body mass, an index that ignores differences in skull morphology, has a statistically significant relationship with bite force (R2 = 0.76) but...

OBJECTIVE A high incidence of snake bite envenomation has been reported from rural India. Due to inadequate epidemiological data, the incidence is underestimated. This study analyses the pattern of snake bite and their management in children in rural areas of Maharashtra, India. To determine the age, mode of presentation, seasonal variation, clinical profile and outcome of patients with snake b...

OBJECTIVE Previous reports indicated that between-muscle substitution of active motor unit pools can be found in a variety of synergist muscles, including shoulder and leg muscles, but little information is available for the masticatory muscles. We hypothesized that, during a prolonged clenching effort performed at low- to moderate-bite force levels, a substitution pattern of activity can be fo...

UNLABELLED The Hyoid Bone (HB) is a singular bone with no articulation, but is associated with some vital functions. The purpose of this study was to test the null hypotheses that there is no change in HB position in individuals with vertical jaw dysplasia. METHODS Eleven factors were used to determine the position of the HB. In this paper the ANOVA (two way analysis of variance) method was u...

This article reports the successful treatment method of scissors-bite correction using miniscrew anchorage and a lingual multi-bracket appliance. A female patient, 17 years and 4 months old, had a chief complaint of crowding of anterior teeth. The patient was given the diagnosis of Angle Class I malocclusion with bimaxillary protrusion and incisor crowding. She also showed a scissors-bite of th...

Raptors exhibit a diversity of strategies to procure their prey but ultimately kill using their beaks and/or talons. Thus, bite and grip forces are ecologically important variables that have direct survival implications. Whereas hawks rely primarily on their feet for killing prey, falcons tend to employ their beaks. Consequently, falcons are expected to achieve relatively greater bite forces, a...

Purpose To perform a comparative analysis of the palatal bone thickness in Thai patients exhibiting class I malocclusion according to whether they exhibited a normal or open vertical skeletal configuration using cone-beam computed tomography (CBCT). Materials and Methods Thirty CBCT images of Thai orthodontic patients (15-30 years of age) exhibiting class I malocclusion with a normal or open ...

animal related injuries as most common causes of human morbidity have different pattern by geographical zones. we aimed to explore the main descriptive epidemiology of animal-related injuries in both rural and urban areas in iran. between 2000 and 2004, we collected the data of all the cases of animal related trauma hospitalized for more than 24 hours in eight cities (tehran, mashhad, ahwaz, sh...

This case report describes the orthodontic-surgical treatment of an adult with Down syndrome and a Class III skeletal malocclusion with posterior open bite, horizontal facial pattern, missing mandibular posterior teeth, and surgical restriction of the mandible.
