OBJECTIVES The aim of this study was to characterise the new hydrophilic fissure sealant, UltraSeal XT® hydro™ (Ultradent Products, USA), and to investigate its in vitro resistance to microleakage after placement on conventionally acid etched and sequentially lased and acid etched molars. MATERIAL AND METHODS The sealant was characterised by Fourier transform infra-red spectroscopy (FTIR), sc...

Resin-based pit-and-fissure sealants are often used to form a barrier on the occlusal surface of molars to treat caries lesions; however, bacteria can remain in the pit and fissures without detection, increasing the risk of secondary caries. Sealants with antimicrobial properties or microbial repellent actions might be advantageous. The aim of this study was to assess the inhibitory effect of a...

OBJECTIVE The purpose of this study was to investigate the efficacy of (Pro Seal) sealant in preventing enamel decalcification in-vivo and compare its effect with fluoride varnish and unfilled sealant using atomic force microscopy. MATERIALS AND METHODS Eight orthodontic patients who were candidates for extraction of all first premolars for orthodontic treatment were recruited to this study. ...

The aim was to test the null-hypothesis that there is no difference in the cumulative survival rate of retained composite resin (CR) sealants and a high-viscosity glass-ionomer Atraumatic Restorative Treatment (ART) sealant in first permanent molars calculated according to the traditional and the modified retention assessment criteria over a period of 3 years. This cluster-randomized controlled...

May/June 2002 This article focuses on the techniques used for successful pit and fissure sealant application by the dental assistant. Pit and fissure sealants first were utilized in 1967 and formally recognized by the American Dental Association in 1971. Since that time, many product developments have been introduced to increase their effectiveness and ease of use. Finding adequate time in the ...

To study the performance of bitumen mixture pavement sealants from their micro-mechanisms, physical properties base bitumen, SBS-modified and epoxy resin sealant as well adhesive sealant-aggregate interfaces were studied using a molecular dynamics simulation. The adhesion sealant-pavement crack wall was contact angle test based on surface energy theory. results show that has excellent propertie...

Objective The aim of this study was to evaluate the retention of glass ionomer sealant, Vitro Molar® (DFL) and Ketac Molar Easy Mix® (3 m ESPE) as pit and fissure sealants on first permanent molars, fully or partially erupted. Methods The study sample consisted of 412 molars, among 110 children. The sealant retention was evaluated after 6 months of the application. Results The results were coll...

PURPOSE The purpose of this study was to investigate the relationship between: (1) children's caries score (dmft, DMFT) at the time of sealant placement; and (2) "success" (measured as being caries-free) of that tooth at follow-up visits. METHODS An existing database of over 38,000 sealants (10,038 children) placed between 1997 and 2002 by the Jefferson County Health Department's Community Ba...

AIM The aim of this study was to investigate the microleakage of pit and fissure sealants in primary teeth and to determine if multi-step methods should produce better results in terms of microleakage prevention. METHODS AND MATERIALS A total of 40 intact primary molars were randomly assigned to one of four sealant groups: resin based sealant Ultraseal XT (US - Ultradent) (Group 1, n=10); adh...
