Development of an intraoral device for social inclusion of a physically disabled patient.

The aim of this study is to describe the use of an intraoral assistive technology for a patient with idiopathic generalized muscular dystonia, presenting temporomandibular disorder and severe anterior tooth mobility and diastema. A multidisciplinary team developed an intraoral device to provide typing and painting functions, and promote relaxation of masticatory muscles without compromising the teeth and supporting tissue structures. The occlusal splint associated with the device promoted muscle relaxation and relief of the signs and symptoms of temporomandibular dysfunction, in this case with generalized muscle dystonia, allowing typing and painting with her mouth without causing tooth mobility or occlusal alteration.

Oral changes stemming from hemangioma of the tongue.

Hemangiomas are among the most common tumors found in children and are characterized by an excess of blood vessels. They most often affect the area of the head and neck, occur with greater frequency among women and Caucasians, and can be found in the oral cavity-especially on the lips, tongue, or mucosa. Clinically, hemangiomas present as asymptomatic red or blue-colored lesions that grow rapidly and are capable of spontaneous regression.

Effect of blood contamination on the shear bond strength at resin/dentin interface in primary teeth.

Purpose: To assess in vitro the shear bond strength at the resin/dentin interface in primary teeth after contamination with fresh human blood.

Methods: 75 crowns of primary molars were embedded in acrylic resin and mechanically ground to expose a flat dentin surface. The specimens were randomly assigned to five groups (n=15), according to the surface treatment.

Shear bond strength to primary enamel: influence of Er:YAG laser irradiation distance.

Purpose: The purpose of this study was to evaluate in vitro the influence of Er:YAG laser irradiation distance on the shear bond strength of an adhesive restorative system to primary enamel.

Methods: Fifty buccal surfaces of extracted human canines were ground and divided into 5 groups (N=10). The control group was etched with 35% phosphoric acid (CA).
