Effect of Er,Cr:YSGG Sub-Ablative Laser Irradiation on Fissure Caries Prevention in Permanent Molars

Recruiting now · Not applicable

Conditions studied: Caries,Dental

In brief

Background: Subjecting human dental enamel to sub-ablative laser has been suggested as a novel way of caries prevention. However, further studies are needed to establish its use as a routine clinical procedure for caries prevention. The aim of this study: This study aims to evaluate the effect of Er,Cr:YSGG subablative laser irradiation on caries resistance of occlusal fissures of permanent molars. Materials and methods: In-vivo study, a split mouth randomized controlled trial with sixty patients having two fully erupted bilateral first permanent molars (ICDAS-II score 0,1 or 2). The pits and fissures will be subjected to sub-ablative power of Er,Cr:YSGG Laser (Group 1, n=90) and will be compared with fluoride varnish application on the first permanent molars in the same arch(Group 2,n=90). DIAGNOdentTM readings and changes in ICDAS-II score will be assessed at base line and at 3,6,9 and 12 months follow-up.
