The aim of the present study was to measure and compare the bond strength of a pit and fissure sealant to tooth
enamel using two new self etching adhesives both in vivo and in vitro. The 1st part of the study was clinical where
75 1 st permanent molars were randomly sealed in children using different techniques. Twenty five molars were
controls where the sealant was applied conventionally using phosphoric acid etching. In the other 50 molars (test
groups) self etching adhesives (Prompt LP and AdheSE) were used as the sole etching and bonding agents (25
molars each). Patients were followed up for 6 months to examine sealant retention. The 2nd part of the study was
laboratory, where 30 freshly extracted human molars received sealant as in the three mentioned approaches.Ten
molars received sealant conventionally (control) and the other 20 molars received sealant using the self etching
adhesives (10 molars each). The specimens were prepared in a manner suitable to be mounted on a universal testing
machine where the shear bond strength of the sealant to tooth enamel was recorded in kg/cm2. Results: None of the
sealants in the control group were lost after 6 months, while in the test groups 3(12%) and 4(16%) of sealants were
totally lost from Prompt LP and AdheSE groups respectively. There were no statistically significant difference
between the 3 groups (Chi square = 5.887). The shear bond strength of the control group was higher than the test
groups but again using one way analysis of variance the difference was not statistically sienificant (P=0.246). It was
concluded from the present study that the use of Prompt LP or AdheSE boding agents beneath sealant without
applying a separate etching step gave acceptable results comparable to the conventional approach. |
