The purpose of this study is to evaluate the dentinal tubule occlusion potential and penetration of Clinpro (R) White Varnish (5% sodium fluoride+tri-calcium phosphate) in the presence or absence of Nd:YAG laser. Seventy-five dentin samples collected from 38 freshly extracted human molars were randomly divided into five groups (n=15). Groups A, B, D, and E were varnished with Clinpro, whereas group C (no treatment) served as the control group. Groups B and E were further irradiated with Nd:YAG laser (1.5W, 10Hz, 1min). All study groups were subjected to pH cycling (kept in 0.3% citric acid 5min/day for 5 days). Groups A, B, and C were evaluated for tubule occlusion using scanning electron microscopy. Groups D and E were evaluated for penetration with confocal laser scanning microscopy (SEM). Non-parametric Kruskall-Wallis and Dunn's statistical tests were used for analysis of SEM results. The penetration depths were analyzed with one-way ANOVA followed by Fisher's Least Significant Difference tests. Tubular occlusion of groups A and B were significantly greater than group C (p<0.05). Tubular occlusion of group B were significantly greater than group A (p<0.05). Penetration depth for group D was significantly greater than group E (p<0.05). Laser application improved the tubular occlusion capacity of Clinpro. Contrary, laser reduced the penetration of Clinpro. SCANNING 38:619-624, 2016. (c) 2016 Wiley Periodicals, Inc.
