This study evaluates, in situ, the effect of an anti-asthmatic medicine on the enamel and dentin of primary teeth. Twenty-eight specimens of enamel and dentin were prepared, selected, sterilized, and stored. Microhardness, microscopic morphology, and initial surface roughness were evaluated.

The purpose of this paper is to present a case report of a child having been born prematurely and diagnosed with hemangioma in the head and neck, emphasizing the dentofacial changes and treatment used to provide care. Severe fibrous scars were found in the perioral region and below the ear that limited the patient's ability to open her mouth.

The aim of this study was to evaluate the shear bond strength (SBS) of two sealants to saliva-contaminated and non-contaminated enamel with and without an intermediate adhesive layer underneath the sealant. Ninety flat enamel surfaces from human third molars were randomly assigned to 6 groups (n=15): F (control): Fluroshield(tm) sealant; EWB (control): Embrace(tm) WetBond(tm); SB/F: Single Bond adhesive system + F; SB/EWB, s-SB/F and s-SB/EWB.

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.

The crowns of one hundred two specimens were subjected to an erosive challenge with HCl and randomly divided into six groups (n = 17): Chocolate Milk (Toddynho® - Pepsico) - negative control; Petit Suisse Yogurt (Danoninho® - Danone); Strawberry Yogurt (Vigor); Apple puree (Nestlé); Fermented Milk (Yakult® - Yakult); and Home Squeezed Style Orange Juice (del Valle) - positive control. The 28-day immersion cycles for the test products were performed twice daily and were interspersed with exposure of the test substrate to artificial saliva.
