A two-year clinical evaluation of pit and fissure sealants placed with and without air abrasion pretreatment in teenagers.
BACKGROUND Long-term retention of pit and fissure sealants is essential for their success . The aim of this study was to compare the retention rates of sealants placed with acid-etching and air abrasion followed by acid etching . METHODS Sixteen subjects aged 16 and 17 years were included in the study . Using a half-mouth design , the authors performed fissure preparation with phosphoric acid gel on r and omly assigned maxillary and m and ibular permanent premolars and molars from one side of the mouth ( Group I ) and performed air abrasion followed by acid etching on the contralateral side of the mouth ( Group II ) . The authors applied sealant material on 162 teeth , and they evaluated the sealants as complete retention , partial loss or total loss at six , 12 and 24 months . RESULTS While fissure sealant retention rates were not significantly different for the two techniques at six months ( P = .97 ) , the retention rates for the teeth in Group II were significantly higher at 12 ( P = .025 ) and 24 months ( P = .002 ) . Molar retention rates were significantly less than those for premolars at each evaluation period ( P < .05 ) . CONCLUSION The sealant retention rates at 12 and 24 months were higher in Group II ( air abrasion followed by acid etching ) . CLINICAL IMPLICATION S As air abrasion followed by acid etching result ed in significantly higher sealant retention rates , this method could be a good choice for fissure preparation before sealant placement for long-term success
