Pit and fissure sealant application updating the technique communitydating com
And the specimens of group A and group B were used for microleakage evaluation.Two types of sealants were evaluated in this study, and they were sealant 3M ESPE Concise (3M ESPE Dental Products, Mc Gaw, USA; Code E) and sealant Helioseal F (Ivoclar Vivadent AG, USA; Code H).These molars were stored in a normal saline solution before use .After the roots of the teeth were cut off, the crowns were embedded in acrylic resin and the buccal enamel surfaces were exposed.Studies have found that the acid-etched enamel surface exposed after the sealant shedding is more susceptible to bacterial damage than the normal nonetched enamel surface [14, 15].
The plaque retentive nature of pits and fissures makes them tough to clean, which causes smooth surfaces not to be more susceptible to caries than pits and fissures .
And lower retention and marginal staining are still worthy of consideration .
The reason why sealants can decrease the incidence of caries is that sealants have high penetration ability and can continuingly resist microleakage .
As a result, the retention of sealants and resistance of microleakage become the true determinant .
Lately, the report of Zhuge has shown that the depth of resin tags inside the dentinal tube can be improved by the subpressure technique .
