Noncarious cervical lesions (NCCLs) are considered to be of multifactorial origin, normally associated with inadequate brushing. This study assessed the influence in vitro of simulated brushing on NCCL formation. Fifteen human premolars were submitted to brushing in the cementoenamel junction region, using hard-, medium- and soft-bristled brushes associated with a toothpaste of medium abrasiven...

BACKGROUND The application of computer-aided design computer-aided manufacturing (CAD CAM) technology in the fabrication of complete dentures, offers numerous advantages as it provides optimum fit and eliminates polymerization shrinkage of the acrylic base. Additionally, the porosity and surface roughness of CAD CAM resins is less compared to conventionally processed resins which leads to a dec...

OBJECTIVE This study evaluated the effects of three post-brushing mouthwashes containing 0 ppm F, 225 ppm F, and 500 ppm F, respectively, on salivary fluoride retention after brushing with 1450 ppm fluoride (as NaF) toothpaste and rinsing with water immediately after brushing. METHODS In this three-phase, randomized, cross-over study, an ion-specific electrode was used to measure salivary F l...

background this study aimed to assess the effects of maternal self-efficacy and oral health-related knowledge on pre-school children oral hygiene behavior. materials and methods this cross-sectional study was conducted on 301 mothers with children aged 2–6 years old randomly selection from health centers of tabriz, iran.  data were collected using self-report questionnaires including demographi...

PURPOSE Our study aimed to test the null hypothesis that whitening and non-whitening dentifrices affect similarly the surface roughness of commercial microhybrid composites, independent of the brushing time. MATERIALS AND METHODS One hundred and ninety-two disc-shaped specimens of Filtek Z250 (3 M/ESPE, St. Paul, MN, USA) and Rok (SDI, Australia) were built up and randomly assigned to 24 grou...

PURPOSE The purpose of this study was to examine tooth-brushing frequency in 575 urban and nearby suburban African American children as part of a comprehensive risk-reduction study for students at high risk for violence, drugs, school delinquency, and unsafe sexual behaviors to determine which covariates predicted tooth-brushing frequency. METHODS Students were surveyed 5 times, from the begi...

Plastic bronchitis (PB) refers to the presence of inspissated Bronchial casts (BC) is uncommon in children.Our case presented with subcutaneous emphysema as the dominant manifestation and was suspected to have foreign body in airway, but bronchoscopy revealed a bronchial cast. Subcutaneous emphysema as the initial/sole manifestation of plastic bronchitis is very rare in children.

Introduction: The guidance given to young children in tooth brushing is important not only for preventing caries and gingivitis but also for teaching young children the concept of oral hygiene, as a first step towards acquiring regular hygienic habits in their daily lives. Aim: To evaluate the tooth brushing ability in children aged 3 to 12 years and its relation to type of grip used, and the d...

PURPOSE Several investigations have demonstrated toothbrush-induced bacteremias. Transient bacteremias are well tolerated by healthy individuals but may increase endocarditis risk in patients with cardiac conditions. This study assessed bacteremia levels after brushing with either the Sonicare electric toothbrush or a manual toothbrush. METHODS Fifty healthy children receiving dental treatmen...
