    Abstract:
    OBJECTIVE: The aim of this study was to evaluate the in vitro effects of Er:YAG laser and an in-office desensitizing paste alone or in combination by using scanning electron microscopic (SEM) analysis. BACKGROUND DATA: Various treatment modalities have been proposed for dentin hypersensitivity, but to date, no single agent or form of treatment has been found effective. MATERIAL AND METHODS: Forty dentine specimens obtained from freshly extracted impacted third molars were included and divided into four groups. Group I served as the control, whereas Group II, Group III, and Group IV recieved Er:YAG laser (30 Hz, 60 mJ/pulse, 10 sec), a desensitizing paste (DP) containing 8% arginine and calcium carbonate, and DP+Er:YAG laser in combination, respectively, evaluated under SEM. RESULTS: SEM analysis presented occlusion and narrowing of dentinal tubules in all treatment groups, but more prominent occlusion was observed in the combined treatment group. Intergroup comparisons regarding the tubule diameters and the number of the open dentinal tubules per 100 μm2 revealed statistically significant difference in favor of combined group (p<0.05). The difference between single effects of Er:YAG and DP in all parameters were found statistically nonsignificant. CONCLUSIONS: The present study has shown that all treatment procedures are effective in dentinal tubule occlusion. However, more prominent occlusion is observed in the combined treatment group.
