Marginal Adaptation of Resin-based Pit and Fissure Sealant Pretreated with Er, Cr: YSSG Laser

Abstract

Background: Proper marginal adaptation of pit and fissure sealant can prevent occlusal caries via prevention of the accumulation of biofilm and the penetration of microorganisms. Hence, the aim of this study was to evaluate the marginal adaptation of the resin-based sealant after fissure pretreatment with Er, Cr: YSSG Laser and compare it to the conventional etching method. Methods:In two equal groups (n=9), 18 extracted premolars were randomly enrolled in the study and pretreated with Erbium, Chromium: Yttrium Scandium Gallium Garnet (ER, CR: YSSG) laser etching in Group I and conventional acid etch in Group II as a surface treatment before application of pits and fissure sealants. After thermocycling and sectioning of the teeth, the Scanning Electron Microscope (SEM) was used to measure the sealant marginal adaption.Results: ER, CR: YSSG laser etching showed higher adaptation of the pits and fissure sealant in comparison to conventional acid etching with a statistically significant difference (p-value=0.0001).Conclusions: ER, CR: YSSG laser etching could be used as an alternative to the conventional acid etching prior to the application of pits and fissure sealant.

Indications, techniques, and outcomes of pit and fissure sealants in pediatric dentistry

“…Automated sealant application: Some dental offices are now using automated systems for applying sealants, which can make the process faster and more efficient. 32 These systems use lasers or other technology to ensure precise placement of the sealant material.…”
