A comparative evaluation of retention of pit and fissure sealant bonded using sixth-, seventh-, and eighth-generation adhesives: An in vivo study

摘要

Introduction: Dental caries is one of the most common preventable childhood infections. a number of measures are available to prevent occlusal caries; pit and fissure sealants are one of the various methods currently available to cost effectively reduce dental caries. Aim: To evaluate the retention of pit and fissure sealant bonded using sixth (Adper promt), seventh (Optibond) and eighth (Futurabond Dual Cure) generations of adhesives. Settings and Design: A total of 37 healthy children who fulfilled the inclusion were randomly selected. A total of 148 teeth (4 in each subject) were used as samples for the study. Methods and Material: The teeth to be sealed were then isolated using rubber dam. The placement of adhesives was done using split mouth design. The first permanent molars were randomly divided into four groups on the basis of sealant placed without and with using 6th, 7th and 8th generation bonding agents as follows: GROUP A (N=37):- Pit and fissure sealant placed without bonding agent. GROUP B (N=37):- Pit and fissure sealant placed following sixth generation bonding agent (ADPER PROMT). GROUP C (N=37):- Pit and fissure sealant placed following seventh generation bonding agent. (OPTIBOND). GROUP D (N=37):- Pit and fissure sealant placed following eighth generation bonding agent. (FUTURA BOND DUAL CURE). The integrity of the sealant placed was assessed immediately after completion of the procedure, 3 months and 6 months after placement. The post-operative evaluation for retention was done using Simonsen criteria. A score of 0 was given for complete retention, 1 for partial retention and 2 for no retention. Statistical analysis used: The statistical analysis was done using SPSS (Statistical Package for Social Sciences) software version 21. Results: It was found that there was no statistically significant difference between the groups after 3 and 6 months as the value obtained (0.133) was much greater than the p-value (0.05). Conclusions: This study concluded that the use of bonding agent prior to application of pit and fissure sealant does not necessarily aid in retention of sealant as compared to pit and fissure sealant placed without bonding agent, Sealants effectiveness is directly related to its retention and it dependent on application procedures. The failure of retention of pit and fissure sealants can attribute to moisture contamination, improper curing methods, inadequate adhesion, improper application procedure or early age placement.
