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 .
Evaluation of the effect of enamel preparation on retention rate of fissure sealant
Background : Prevention from caries is a principle in dentistry and fissure sealant therapy is being used as a preventive method success of sealants is directly depending on their retention . Aim : The Aim of the present study is to evaluate effects of enamel preparation on sealant retention . Setting s and Design : Clinical trial . Material s and Methods : About 57 children aged 6 - 8 year old took part in this study . 200 first molar teeth of these children has been r and omly separated into two groups : A case group ( Mechanically preparation of enamel ) and a control group ( conventional method , without preparation ) . After applying fissure sealants children were followed up 6 months later . Statistical Analysis Used : Mann- U- Whitney Test was used . Results : Complete retention after 6 month follow up was 86.7 % in case group and 82.8 % in control group . No significant difference was seen between the groups after 6 month follow up . ( P = 0.508 ) . Conclusion : Although statistical evaluation did n't show significant difference , but sealant retention was more after preparation technique
