The purpose of this study was to determine the combined retention rates of two Bis-GMA sealants ("Delton" and "Nuva-Seal") in a pedodontic clinic. Included in this study were 176 patients whose mean age was eleven years and five months. For all teeth examined, the relationship between the percentage of teeth with "sealant all present" and longevity is almost linear from the plotted value at six...

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...

PURPOSE The aim of this work is to study and compare the retention rate, caries-preventing and antibacterial effects of resin-modified glass ionomer and flowable composite in comparison to conventional fissure sealant. METHODS Forty-five children aged 7-10 years with newly erupted lower first permanent molars were randomly divided into three equal treatment groups. Group I: sealed by a conven...

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...

OBJECTIVE To compare the penetration and adaptation of a moisture tolerant resin-based sealant with a conventional resin-based sealant in different occlusal fissure types in vitro by scanning electron microscopic (SEM) technique. METHODS Fifty sound, intact extracted premolars and third molars were included. They were randomly and equally allocated to receive either Seal-Rite (conventional re...

A variety of pit and fissure sealants are used clinically to protect the occlusal surfaces of teeth against dental caries. A new chemically activated bis-GMA type sea­ lant, Delton Pit and Fissure Sealant, has recently be­ come commercially available. The Delton Etching So­ lution supplied with the sealant contains 35 per cent orthophosphoric acid. The tensile bond strength of this sealant to e...

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: Fibrin sealant is a biological tissue adhesive mimicking the final stage of coagulation. It has a wide variety of application in the field of periodontics. The aim of this article was to review current applications and identify potential use of fibrin sealant in periodontal surgical procedures on an evidence-based conclusion. Materials and methods: An online search was performed in PubMed,...

AIM To evaluate the effect of amorphous calcium phosphate (ACP)-containing pit and fissure sealant on inhibition of enamel demineralization in vitro. MATERIALS AND METHODS Enamel specimens (n = 75) were prepared using freshly extracted noncarious human third molars. Box-shaped cavities (8 × 2 × 2 mm) on the buccal or lingual surfaces were prepared and restored with resin-based sealant (Concis...
