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 .
Retention and effectiveness of dental sealant after 15 years.
This l and mark study of a pit and fissure sealant found 27.6 percent complete retention and 35.4 percent partial retention on permanent first molars . In the matched pair analysis , carious or restored surfaces made up 31.3 percent of the surfaces in the sealed group and 82.8 percent in the unsealed group
