In finches husking time is non-linearly related to the ratio of seed hardness to maximal bite force. Fringillids produce larger bite force and husk relatively hard seeds faster than estrildids of similar size. This is at least partly explained by their relatively larger jaw muscle mass and a difference in husking technique. However, the effect of differences in skull geometry on bite force is u...

BACKGROUND The pathogenic mechanism of snake-bite induced acute kidney injury (AKI) remains unclear. Analyzing the risk factors for snake-bite induced AKI may provide the guidance needed for AKI prevention and early treatment. MATERIAL AND METHODS This retrospective study included 119 snake-bite patients who were hospitalized at the emergency department of Sichuan Provincial People's Hospital f...

OBJECTIVE To estimate the prevalence of malocclusion and to examine the effects of breastfeeding and non-nutritive sucking habits on dentition in six-year-old children. METHODS A cross-sectional study was carried out nested into a birth cohort conducted in Pelotas, Southern Brazil, in 1999. A sample of 359 children was dentally examined and their mothers interviewed. Anterior open bite and po...

AIM To assess the degree of jawbone asymmetry by drawing vertical lines on digital panoramic radiographs of paediatric patients with right or left unilateral cross-bite. MATERIALS AND METHODS STUDY DESIGN The sample consisted of 217 paediatric patients of both genders, aged 6-9 years. A set of vertical lines was drawn on the side of the mandible with the cross-bite and on the side without ...

Forensic dentistry is an essential part of Forensic science, mainly involves the identification of an assailant by comparing a record of their dentition (set of teeth) with a record of a bite mark left on a victim. Human bite-mark traditionally provides the forensic dentist with both physical and biological evidence. Bites have been found in cases of homicide, attempted suicide, sexual assault,...

BACKGROUND Mammalian bite injuries create a public health problem because of their frequency, potential severity, and increasing number. Some researchers have performed fragmentary analyses of bite wounds caused by certain mammalian species. However, little practical information is available concerning serious mammalian bite wounds that require hospitalization and intensive wound management. Th...

Introduction Open bite malocclusion in adults is considered to be one of the most difficult problems to treat because of its complicated etiology. The etiology of the open bite is multifactorial: genetic and/or environmental factors. The factors ranging from vertical maxillary excess, abnormalities in dental eruption, open bite skeletal pattern and tongue posture problems contributes to this co...

Bite force is one of the most utilized performance measures due to its association with feeding and consequently fitness. Due to their large size and the concomitant increase in the adductor muscles it is expected that apex predators may rely on high biting performance allowing for increased dietary breadth. Billfish are apex marine predators characterized by the extreme elongation of the upper...

BACKGROUND Snake bite is a neglected public health problem in the world and one of the major causes of mortality and morbidity in many areas, particularly in the rural tropics. It also poses substantial economic burdens on the snake bite victims due to treatment related expenditure and loss of productivity. An accurate estimate of the risk of snake bite is largely unknown for most countries in ...
