Whitening Dentifrices Effect on Enamel with Orthodontic Braces after Simulated Brushing.

Objective:  This study aimed to evaluate the effects of whitening dentifrices on enamel color, the shear bond strength of orthodontic brackets and adhesive remnant index (ARI).

Materials And Methods:  Eighty bovine teeth with brackets were randomly divided into four groups ( = 20): control group (GC)-water, test group 1 (GT1)-Colgate Total 12, test group 2 (GT2)-Curaprox Black Is White, and group test 3 (GT3)-Luminous White. All groups were submitted to brushing, simulating 12 months.

Prevalence of risk factors for oral diseases in obese patients referred for bariatric surgery.

Background: Obesity is a risk factor for several chronic diseases, and scientific evidence suggests an association between obesity and oral diseases. In this study, the authors estimated the prevalence of risk factors for caries, dental erosion, and periodontal disease in a group of obese patients referred for bariatric surgery.

Methods: The authors invited obese patients who were referred for bariatric surgery at a private center for treatment of obesity to participate in this study.

Association between childhood obesity and oral hygiene status.

Objective: The purpose of this study was to evaluate the oral hygiene status in pediatric obese patients.

Methods: A cross-sectional study was conducted from 2011 to 2012, which evaluated 180 Brazilian pediatric patients, 6-14 years old, girls and boys, recruited according to two Body Mass Index (BMI) categories: obese and non-obese (healthy weight). For the evaluation the oral hygiene status, the study used Oral Hygiene Index (OHI) and Gingival Bleeding Index (GBI).

The oral manifestations of celiac disease: information for the pediatric dentist.

Purpose: The purpose of this article was to present a literature review of oral manifestations reported by celiac disease patients.

Methods: A review of the published literature for oral manifestations present in celiac disease patients was conducted from the following databases: PubMed(®); MEDLINE; Web of Science; Science Direct; and Scielo.

Results: According to some literature studies, prevalence of enamel defects and recurrent aphthous stomatitis was observed in approximately 10% to 96% and 4% to 41% of 2- to 86-year-old celiac patients, respectively.

In vitro study on tooth enamel lesions related to whitening dentifrice.

Background: The tooth whitening substances for extrinsic use that are available in Brazil contain hydrogen peroxide or carbamide peroxide. Several studies have attributed the appearance of lesions in the enamel morphology, including hypersensitivity, to these substances. Such lesions justify fluoride therapy and application of infrared lasers, among other procedures.

Efficacy of 35% hydrogen peroxide on human enamel: in vitro evaluation in different tooth areas.

This study aimed to assess the efficacy of a 35% hydrogen peroxide--based gel without activation in vitro on three areas of the tooth surface. Vestibular faces of human premolar teeth were darkened, followed by two whitenings at 7-day intervals. The efficacy of whitening was determined in the cervical third, medium third and incisal third of the tooth surface with an Easyshade-Vita spectrophotometer based on the CIELab system.

Susceptibility to carieslike lesions after dental bleaching with different techniques.

Objective: To assess the influence of dental bleaching on the susceptibility of developing carieslike lesions.

Method And Materials: Enamel slabs obtained from recently extracted human third molars were submitted to different bleaching techniques: at-home, with 10% and 16% carbamide peroxide (G1 and G2, respectively; Whiteness Perfect); and in-office, with 37% carbamide peroxide (G3; Whiteness Super) and 35% hydrogen peroxide (G4; Whiteness HP), activated by light-emitting diode and laser. The control groups G5 and G6 were not bleached.
