The universal bite block is increasingly used in orotracheally intubated patients. Here, we report a case of pilot tube dysfunction caused by a malpositioned universal bite block in an orotracheally intubated patient. We summarize the key points on identifying and managing a malpositioned universal bite block from this case and literature review.A 74-year-old woman was emergently intubated duri...

Jaw reflexes evoked by mechanical stimulation of teeth in humans. The reflex response of jaw muscles to mechanical stimulation of an upper incisor tooth was investigated using the surface electromyogram (SEMG) of the masseter muscle and the bite force. With a slowly rising stimulus, the reflex response obtained on the masseter SEMG showed three different patterns of reflex responses; sole excit...

Control of the height of posterior dentoalveolar regions is of great importance for the correction of skeletal open bite. Traditionally, second premolar extraction facilitates the closure of open bite by inducing a counterclockwise mandibular rotation without molar intrusion. This article reports treatment for a 24-year six-month-old female patient with an open bite and large anterior facial he...

BACKGROUND/AIMS Techniques for endoscopic evaluation of gastrointestinal subepithelial lesions include conventional endoscopy, jumbo biopsy, endoscopic ultrasonogrphy (EUS), EUS-guided fine needle aspiration, and endoscopic submucosal resection. However, these procedures have many limitations, such as low diagnostic yields and high complication rates. We therefore evaluated the diagnostic yield...

This study compared the peak isometric strength of the cervical flexors in deep bite temporomandibular dysfunction (TMD) patients while biting in four bite positions: habitual occlusion, edge-to-edge, lateral shift and retruded. These values were then compared to those of the same subjects' bite positions elevated to a functional criterion (maximum isometric strength of the deltoid muscles). Th...

1878-3317/$ e see front matter Copyright 2013, Ta http://dx.doi.org/10.1016/j.jecm.2013.01.004 The complexity of anterior open bite is attributed to a combination of skeletal, dental, soft tissue, and habitual factors. Multiple treatment strategies aimed at different etiologies of anterior open bite have been proposed. However, the tendency toward relapse after conventional or surgical orthodon...

Performance measures associated with the vertebrate jaw system may provide important insights into vertebrate ecology and evolution because of their importance in many ecologically relevant tasks. Previous studies have shown that in many taxa, evolution toward higher bite force has gone hand in hand with the evolution of larger body size. However, independent of differences in overall body size...

Conclusions Bite infections can contain a mix of anaerobes and aerobes from the patient’s skin and the animal’s oral cavity, including species of Pasteurella, Streptococcus, Fusobacterium, and Capnocytophaga. The most common pathogens associated with bite wounds are Streptococcus species, Staphylococcus species, Pasteurella multocida, Capnocytophaga canimorsus and anaerobic bacteria. Sporadical...

Animal bites continue to pose major public health challenges, and the clinical sequelae of bite injuries can extend far beyond simple wound management. Identification of people bitten by animals remains incomplete, and inconsistencies in data collection preclude meaningful conclusions about bite circumstances and predisposition of specific breeds of dogs to bite or inflict severe bites.
