OBJECTIVE The aims of this study were to investigate the effectiveness of sealant placement under the guidelines of the Oral Health Promotion Program for Children and Adolescents (Portugal), and to test the influence of clinical and socioeconomic variables on the DMFT increment in 277 children, born in 1997. MATERIAL AND METHODS A dental hygienist performed the initial examinations and sealan...

Background. Wear resistance of pit and fissure sealant materials can influence their retention. Wear characteristics of sealant materials may determine scheduling of check-up visits. The aim of this study was to compare wear resistance of two flowable composite resins with that of posterior composite resin materials. Methods. Thirty-five disk-shaped specimens were prepared in 5 groups, includin...

Objective: To compare the retention and marginal discoloration of Self-etch Total Etch Adhesive during Pit Fissure Sealant application at 1 month, 3 months, 6 12 months. Materials methods: 30 school-going children received sealants in all four permanent second molars, carried out Department Pedodontics Preventive Dentistry. The fully erupted molars were randomly allocated into groups: group A (...

HYPOTHESIS Application of skin sealant prior to incision reduces microbial contamination of the wound. DESIGN Prospective, randomized, multicenter clinical trial. SETTING Six teaching hospitals. PATIENTS A total of 177 adult patients undergoing elective open inguinal hernia repair were randomized to either standard skin preparation with 10% povidone-iodine or skin preparation followed by ...

The utilization of fibrin sealants to augment hemostasis, seal tissues, and facilitate targeted delivery of drugs is increasing. In 1985, a hospital-based program was established to provide autologous and allogeneic cryoprecipitate that serves as a fibrin sealant when combined with bovine thrombin. To date, more than 4,000 patients have been treated with this product at our institution, with an...

Twelve bituminous hot-pour crack sealants were evaluated over four years in temperatures ranging from –40°C to +40°C. Each sealant was evaluated over 900 linear meters of transverse and longitudinal routs of 12 × 12 mm2, 19 × 19 mm2, and 40 × 10 mm2 (width × depth). Results show that sealant source, rout size, and rout orientation affected sealant performance, i.e., debonding and pull-out level...

OBJECTIVES Application of sealants is a safe and effective way to prevent occlusal caries in the posterior teeth. A successful sealant therapy depends on good isolation. Decreased steps of adhesive application may enable proper isolation and use of self-adhering flowable composites for sealant therapy. This study sought to compare the marginal microleakage of fissure sealants and self-adhering ...

This study investigated the effect of sealant application on the color stability of composite resin restorations. Cavities in bovine incisors were restored with composite resin (Opallis; FGM) and the teeth were assigned to 4 groups (n=10). A sealant (Fill Glaze; Vigodent) was applied over the restorations of 2 groups. Baseline color measurements based on the CIEL*a*b* system were carried out us...

Earlier studies have reported extensive volumetric loss of fissure sealant shortly after placement. To determine the volume of fissure sealant lost at six months, we used a servohydraulic profilometric apparatus in combination with computer graphics. Twenty-two premolar teeth were selected, and baseline silicone impressions were made of each tooth. The teeth were sealed and the occlusion adjust...

There are no published research reports on the prevalence of dental sealant use in children in Saudi Arabia. This study determined the prevalence and socioeconomic indicators of dental sealant use on the permanent molars of a stratified random sample of schoolchildren in Jeddah. A basic oral screening survey of students was conducted by dentists and a self-administered questionnaire was complet...
