Sixty-four human teeth with class V caries that measured with DIAGNOdent were used. The samples were divided into four groups (n = 16) randomly according to caries removing methods of conventional method, Carisolv, Papacarie, and Er,Cr:YSGG laser system. The self-etch Clearfil SE Bond and Clearfil Majesty Es-II were used as restoration materials. After thermal cycles of 2,000 (5 and 55 degrees C) samples were immersed in a 50% wt/wt AgNO3. Samples were finally imaged and scored under light microscopy and SEM, respectively. The data were statistically analyzed using Kruskal-Wallis H, pairwise comparison and Wilcoxon's T tests at 5% significance level (p < .05). Statistical analysis demonstrated that there was no significant difference between microleakage scores in dentin regions but there were significant difference between the Papacarie and Er,Cr:YSGGlaser in terms of leakage scores in enamel sites. No statistically significant difference in leakage scores emerged between light microscopy and SEM.eninfo:eu-repo/semantics/closedAccesschemomechanical methodErCrYSGG lasermicroleakagePapacarieArticle8291566157410.1002/jemt.233222-s2.0-8506734919631199544Q1WOS:000481788100019Q1
