One study reported that laser preparation as an adjunct to acid-etching enhanced the retention rate .
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 .
Conclusion The present limited evidence suggests that lasers could be an effective pretreatment method .
The retention rate was similar to that of conventional acid etching .
Background This systematic review aim ed to assess the clinical effects of laser preparation compared to other types of chemical or mechanical preparation of tooth surfaces used in fissure sealant placement .
Effect of acid etching and different Er:YAG laser procedures on microleakage of three different fissure sealants in primary teeth after aging.
The purpose of this study was to evaluate the effects of different surface conditioning procedures on microleakage and unfilled area proportions of three fissure sealants(Aegis , Helioseal and Helioseal F ) in primary molar teeth . One hundred and fifty teeth were r and omly divided into five main groups according to surface conditioning procedures . Main groups were ; acid-etching(Group A ) ; laser 3.75 W(Group B ) and 5 W(Group D ) ; acid-etching combined with laser 3.75 W(Group C ) and 5 W(Group E ) . Sample s were aged by thermocycling and water bath . Afterwards , they were immersed in basic fuchsin solution for 24 h and bucco-lingual sections were obtained from each tooth . Digital images were taken using a stereo-microscope and the microleakage and unfilled area proportions were assessed by using a software system . Consequently , Aegis FS containing amorphous calcium phosphate was found to exhibit the lowest microleakage in all surface conditioning procedures . Unfilled areas were not detected in Groups C and E of all FSs
