Traditional non-destructive methods of diagnosing pit and fissure caries, such as explorers and radiographs, have limited use in the detection of both early lesions and lesions extending well into dentin.1-3 Furthermore, bacteriological sampling of early dentin lesions provides little reason to believe that we can effectively “seal in” decay when present.4,5 With the emergence of pit and fissur...

AIM The anatomical pits and fissures of the teeth have long been recognized as susceptible areas for the initiation of dental caries. The extreme vulnerability to decay of these pits and fissures on the occlusal surfaces has prompted dental scientists to seek methods of caries prevention. Motivated by the role of pit and fissure sealants in caries prevention, the aim of this study was to compar...

PURPOSE The purpose of this study was to evaluate the retention rate and the caries increment differences between a light cured, F releasing filled fissure sealant and a non-F nonfilled one. METHODS The two different fissure sealants (Fluoroshield, Delton) were placed on all 4 caries-free first permanent molars of 112 children aged 7-8 years, under a half-mouth experimental design. All the ch...

BACKGROUND Marginal seal has a principal role in durability and clinical success of fissure sealants. The aim of this study was to compare the microleakage of two materials used as pit and fissure sealant with different methods of application. METHODS The 55 extracted premolars were assigned randomly to one of the following five groups: Group 1: Acid-etching (ultra-etch) + fissure sealant (co...

BACKGROUND Dental caries among children is one of the greatest challenges faced by dentists globally; especially that of susceptible surfaces like the Pit and fissures. Dental sealants have proved to be an effective way to prevent caries development. The Clinical success of any material depends upon its adhesion to tooth structure, resistance to wear and ability to withstand the masticatory or ...

OBJECTIVES This study undertook a retrospective evaluation of the effect of sealants on the caries experience of initially sound and incipient permanent first molar pit and fissure surfaces. METHODS Records of children with complete five-year records were obtained from a school-based dental sealant program in a fluoridated community. Sealants were placed on 677 tooth surfaces in 96 children; ...

OBJECTIVES Wear simulations may provide an indication of the clinical performance of pit-and-fissure sealants when associated with primary teeth as counterbody, restricting the involved variables. The aim of this study was to evaluate wear of dental materials used as pit-and-fissure sealants in contact with primary teeth. MATERIALS AND METHODS A resinous sealant (Fluroshield(®)) and a resin-m...

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...

BACKGROUND AND PURPOSE We assessed cross-sectional and longitudinal relationships between whole brain white matter hyperintensity (WMH) volume and regional cortical thickness. METHODS We measured WMH volume and regional cortical thickness on magnetic resonance imaging at ≈73 and ≈76 years in 351 community-dwelling subjects from the Lothian Birth Cohort 1936. We used multiple linear regression...

The aim of this study was to investigate retention of composite fissure sealant polymerized with standard and soft-start technique after a three year clinical trial. One hundred teeth were divided into two groups (A&B) of teeth and sealed with composite material (Visioseal, 3M Espe) using split mouth design. Sealants were polymerized using standard (Group A) and soft-start (Group B) techniques ...
