UNLABELLED The penetration of a sealant into the tooth fissures can establish longer retention time for a pit and fissure sealant restoration. AIM This in vitro study was to evaluate the penetration ability of two low-viscosity resin materials, a composite and a compomer, applied with and without their bonding agents in comparison to an unfilled resin sealant. METHODS Forty premolars with s...
PURPOSE This study examined the effects of a widely used (Delton Pit & Fissure Sealant - Light Cure Opaque, DENTSPLY Professional, York, PA) pit and fissure sealant material on bisphenol A (BPA) levels in blood and saliva, among both low and high-dose groups over time. METHODS A convenience sample of 30 adults from the Old Dominion University population were randomly and evenly divided into 2...
INTRODUCTION/AIM To appraise the clinical literature in determining whether loss of complete sealant retention as surrogate endpoint is directly associated with caries occurrence on sealed teeth as its clinical endpoint and to apply the appraised evidence in testing the null-hypothesis that the retention/caries ratio between different types of sealant materials (resin and glass-ionomer cement) ...
Comparison of Helioseal F microleakage with 37% phosphoric acid and self – etch primer (In - vitro) Dr. Z. Bahrololoomi* - Dr. M. Nyazmand** *- Assistant Professor of Pedodontics Dept. - Faculty of Dentistry – Shaheed Sadoughi Yazd University of Medical Sciences. **- Dentist. Background and Aim: Recently, the use of self – etch primers, due to their ease of manipulation, for fissure sealant the...
Recently, a great deal of effort has been concentrated in the area of preventive dentistry. Among the many products to evolve from this effort are materials designed to obtund and to seal occlusal pits and fissures from the ingress of saliva and food particles. Topical and systemic fluoride treatments have proven effective in the reduction of smooth surface caries, but have shown little or no e...
STATEMENT OF THE PROBLEM Fissure sealant therapy is among the most effective methods of preventing dental caries. However, it is lengthy and isolation of the teeth is difficult in this procedure especially in young children. Using new hydrophilic fissure sealant may reduce such problems. PURPOSE This study aimed to evaluate the clinical success of a hydrophilic fissure sealant on the lower pe...
Introduction: Due to concerns about histological caries and recurrent caries after the use of sealants, adhesive systems containing fluoride and antibacterial agents have been proposed. The aim of this study was to evaluate the microleakage of sealants after the use of antibacterial chlorhexidine solution on etched enamel with and without the use of fifth- and sixth-generation adhesive systems....
Background and Aim: Although there have been several epidemiologic studies on first permanent molar caries in Iranian students, the need for endodontic therapy has not been investigated so far. The purpose of this study was to assess the need for first molar root canal therapy in 7- to 11-year-old schoolchildren and its association with age, gender, and parent education level. Materials and Met...
OBJECTIVE The aim of this study was to evaluate the effects of enamel or dentin bonding agent (DBA) and sealant viscosity on sealant microleakage. MATERIALS AND METHODS Sixty extracted human premolars were randomly divided into two equal groups (based on sealant viscosity) and each group was divided into three subgroups of 10 teeth. Group 1 (low viscosity sealant, Seal-Rite, Pulpdent, USA wit...
