AIM The aim of the study was to evaluate the effect of saliva contamination and compare the microleakage of three different pit-and-fissure sealants namely, Helioseal F, Enamel Loc and Fuji VII. MATERIALS AND METHODS Sixty recently extracted sound third molars were randomly assigned to three groups for three different sealant materials (n=20). Each sealant group was then randomly divided into...

This study evaluated the effect of different types of filler in a resin-based pit and fissure sealant on fluoride release, recharge, and lactic acid neutralization. Resin-based sealant was incorporated with 5% w/w of the following fillers: calcium aluminate cement (CAC), synthesized mesoporous silica (SI), a CAC and SI mixture (CAC+SI), glass-ionomer powder (GIC), and acetic acid-treated GIC (G...

However, the best method for cleaning the pits and fissures has not been agreed upon. Taylor and Gwinnett3, Garcia-Godoy and Gwinnett4,5, and GardaGodoy and Medlock6 showed that pumice particles become lodged in the fissures and are not removed after rinsing with a stream of water. Main et al. 7 demonstrated that the acquired pellicle is removed completely by standard acid-etching and Donnan an...

the efficacy of correctly applied fissure sealants has been revealed in the prevention of caries. saliva and moisture contamination of the etched enamel surface before sealant placement can decrease the bonding strength of the sealant to the enamel. the aim of this study was to test the new bonding agents containing nano-fillers in order to reduce the negative effect of saliva contamination on ...

OBJECTIVES This study was conducted to evaluate Yemeni dental practitioners' knowledge and practices concerning fissure sealants. MATERIALS AND METHODS A modified questionnaire consisted of 25-items was distributed to 500 dentists working in Sana'a City. Descriptive statistics and Chi-square/Fisher's exact tests were used for statistical analyses. RESULTS The response rate was 74%. Most of ...

Visit Chiesi at Stand D.30 TUESDAY, SEPTEMBER 27TH 2011 patients underwent a second treatment session after 12 weeks in the contralateral upper lobe to complete bilateral therapy. Pulmonary function, functional capacity, and quality of life assessments were performed at 3 and 6 months following treatment. Results: Upper lobe ELS therapy in this cohort (8 male, age 63±6 y...

OBJECTIVES Despite the increasing use of Internet, there is no supervision over the accuracy and quality of the information provided in the web. To deal with this problem, health specialists should take part in planning, publishing and supervision of online health-related information. The aim of this study was to evaluate the quality of information related to pit and fissure sealants in Persian...

Introduction: Sealing pits and fissures was introduced as an approach to prevent occlusal caries for more than two decades. The aim of this study was to compare the microleakage of flow able resin reinforced glass ionomer (Ionoseal) with other materials used as fissure sealants. Methods: In this in vitro study, 50 premolar teeth of human free of any caries were selected. Fissurotomy was done...
