Effect of Er:YAG Laser on Hydrophilic Sealants

This study was conducted on 44 (19 girls and 25 boys) patients presenting 132 permanent first molars, who applied for oral examination to Adnan Menderes University Faculty of Dentistry Department of Pediatric Dentistry. The patients involved in the study were aged between 7-11 years who had fully erupted permanent first molars, which were suitable for non-invasive fissure sealant application (narrow, deep fissures).

About this study

The permanent first molar teeth were cleaned using a polishing brush and pumice and isolated with cotton rolls. Caries status was assessed using DIAGNOdent pen (DIAGNOdent pen 2190, KaVo, Biberach, Germany) at the occlusal and proximal sites. Teeth having DIAGNOdent readings of 12 or less at the occlusal site and 7 or less at the proximal site were included in the study. Then, the teeth were divided into three groups. The first group (Grup A) of teeth were etched with phosphoric acid, the second group of teeth (Group L) were etched with Er:YAG laser and the third group of teeth (Group A+L) were etched with both Er:YAG laser and phosphoric acid. The patients were recalled for follow up examination at the 3rd, 6th and 9th months. The teeth were assessed using mouth mirror and explorer regarding new caries formation and retention of the fissure sealants. The obtained data were analyzed using SPSS 24.0 (SPSS 24.0 for Windows, SPSS Inc., Chicago, IL, USA).
