A five years clinical evaluation of sealed occlusal surfaces of molars.
BACKGROUND Air-abrasion can be used for enamel preparation before fissure sealing as well as acid etching which is the evidence -based method for enamel preparation before sealing . AIM The aim of this study is to evaluate the status of sealed occlusal surfaces of the first permanent molars after one , two , and five years and to compare consequence of using the two different methods for enamel preparation before sealing . MATERIAL S AND METHODS At the baseline of the study 88 children of the age from 6 to 9 with caries-free permanent molars r and omly received  185 sealants after using the air-abrasion system KCP 2000 PLUS ( ADT Inc. ) and 121 sealants using the acid etching method with Vococid ( VoCo ) . Fissurit F ( VoCo ) was used for sealing . The status of occlusal surfaces of molars was scored as caries- free or decayed/restored by visual clinical assessment evaluation after one , two , and five years . RESULTS The sealants retention rate was 97.2 % , 91.9 % , 61.2 % in the air-abrasion group and 96.3 % , 92.6 % , 62.4 % in the acid etching group after one , two , and five years , respectively . The results showed 98.2 % , 98.0 % , 89.8 % caries free occlusal surfaces of molars prepared with air-abrasion method and 100 % , 100 % , 94.6 % caries free occlusal surfaces of molars prepared with acid etching method after one , two , and five years respectively . CONCLUSION The differences between the two methods : air-abrasion and acid etching in terms of sealant retention rate and caries development appeared to be statistically insignificant ( p>0.05 )
