Retention of sealants was checked using Simonsen’s criteria of sealant retention after three and six months of sealant application.
Combining air abrasion pretreatment with subsequent acid etching did not result in statistically significant difference in sealant retention compared to acid etching alone in both primary and permanent molars after 3 and 6 months follow up.
This study attempts to evaluate and compare the efficacy of two enamel surface pretreatment techniques - Acid etching alone or combination of air abrasion followed by acid etching technique.
The present study is a longitudinal experimental study carried out after obtaining prior approval from the Ethical Committee of the Institution.
Each child selected for the study received preventive treatment of application of pit and fissure sealants in the form of split mouth design.
However, concern has been expressed that the traditional acid etch technique for sealant placement does not allow for complete cleaning of the pits and fissures prior to sealant placement (6).
After suitable selection of rubber dam clamps, teeth were isolated either arch wise or quadrant wise as per convenience and cooperation of the child.2.
ENAMEL SURFACE PRETREATMENT(a) For Group A (Acid etch only): 37 % phosphoric acid solution was applied to primary second molar and permanent first molar occlusal pits and fissures with the help of applicator tip and left for 15 seconds for etching to occur.
Fissure sealing has been shown to be an evidence- based caries preventive method for protecting the occlusal surfaces against caries (2).
Non- sealed teeth need to be restored approximately 50% more frequently compared to their sealed counterpart (3).

However, marginal leakage studies have shown that air abrasion alone is not as effective as air abrasion coupled with acid etching in preventing microleakage (7).
