No significant difference in the incidence of caries was reported .
And no significant differences were found in heart rates , oxygen saturation or degree of the patient dental anxiety between acid-etching and laser preparation .

Pit and Fissure Sealant Retention Following Air Abrasion Preparation with Bioactive Glass and Aluminum Oxide Particles.
PURPOSE Alumina air abrasion is an alternative for acid-etch technique for tooth preparation before placement of a fissure sealant . The aim of this study was to compare the retention of sealants placed subsequent to air abrasion with alumina and bioactive glass ( BAG ) particles . METHODS Sixty-two 6 - 12 year old children were included in this study . Using a halfmouth design , the fissures were prepared using air abrasion with alumina particles on r and omly assigned permanent m and ibular or/ and maxillary first molars on one side of the mouth ( Group 1 ) and air abrasion with BAG on the contralateral side of the mouth ( Group 2 ) . Sealants were applied on 180 teeth , and were scored as missing , partially retained , and completely retained after three , six , nine and 12 months . Data were analyzed using Friedman and Wilcoxon tests ( α=0.05 ) . RESULTS Sealant retention rates in the alumina group were higher than those in the BAG group at all time periods ( P<0.001 ) . CONCLUSIONS Sealant retention after air abrasion with alumina particles was higher than BAG over 12 months
