recently, self-etching fissure sealants have been introduced to reduce technical sensitivity; however, their efficacy should be assessed. the aim of this study was to assess of the microshear bond strength of self-etching and conventional fissure sealants.thirty non-carious third molars were randomly divided into three groups (n=10). microcylinders of concise fissure sealant were bonded to prep...

objective: long-term retention of pit and fissure sealants is crucial for their success. this clinical study evaluated the retention rate of a flowable composite resin (filtek supreme xt flowable restorative) compared to a conventional resin-based sealant (concise light cure white sealant) over 12 months. materials and methods: forty subjects aged 6 to 9 years were included in the study. using ...

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...

An investigation of pit and fissure sealant retention in 1,871 children in the Head Start program was conducted in Tennessee in September 1985 to determine the retention of the sealant after application to the occlusal surfaces of primary molars of 3- and 4-year-old children. The investigation shows pit and fissure sealants are retained on primary molars at a rate comparable to that expected on...

Aims and objectives: The aim of this in vitro study was to evaluate self-adhering composite Dyad flow (Kerr, USA) as a pit and fissure sealant. The objectives were to assess the degree of microleakage with self-adhering composite Dyad flow and that with Fissurit F as pit and fissure sealants and, to compare the same between these two materials. Materials and Methods: 20 premolars extracted for ...

BACKGROUND The purpose of this study was to investigate and compare three different pit and fissure sealants with different composition to check their effectiveness for sealing ability and microleakage. MATERIALS & METHODS Total 120 therapeutically extracted premolars devoid of any caries, anomalies or morphogenic diversity were collected and distributed equally in three groups (40 in each). ...

background: marginal seal has a principal role in durability and clinical success offissure 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 ofthe following five groups: group 1: acid-etching (ultra-etch) + fissure sealant (conv...

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...
