Design:
Randomized controlled trial.
Study Population:
Forty-seven schoolchildren aged 9-10 years with fully sound/noncavitated erupted first permanent molars were included and randomly allocated in control and experimental groups in a split-mouth design.
Cases:
47 schoolchildren (94 molars) fissure sealants applied using self-etch universal adhesive system.
Controls:
47 schoolchildren (94 molars) fissure sealants applied using conventional acid-etching technique.
Outcome Measure:
Retention of sealants and secondary caries incidence (ICDAS).
Data Analysis:
Chi-square test.
Results:
Conventional acid-etch sealants retention was superior to self-etch after 6 and 24 months (p < 0.001), but no differences were found in caries incidence after 6 and 24 months (p > 0.05).
Conclusions:
Clinical retention of fissure sealants using conventional acid-etch technique is greater than self-etch.
