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.
Participants of age 6-12 years old
Patients ranking definitely positive or positive on Frankl behavior rating scale
Having at least two bilateral fully erupted first permanent molars with untreated non-cavitated occlusal surfaces with deep grooves, the included teeth will have International Detection and Assessment System (ICDAS-II)/ severity scores 0, 1 or 2
Initial DIAGNOdent Score not exceeding value of 25 indicating only enamel involvement
Patients with any known medical history of systemic diseases
Patients having first permanent molar with hypoplastic or hypocalcified enamel
Patients using medications that may affect the oral flora or salivary flow
Patients treated with in-office fluoride treatment within the last 3 months prior to being enrolled in the study.
