ABSTRACT
Objective This in vitro scanning electron microscopic (SEM) study aimed to compare the effect of ErYAG laser and a commercially launched dental product namely 8% arginine-calcium carbonate on exposed dentinal tubules. Materials and methods A total of 120 tooth samples prepared from healthy maxillary first premolars extracted due to orthodontic reasons were grouped randomly into four groups of 30 samples each - Group I control group (C); Group II laser group (LG); Group III toothpaste group (TP) and Group IV laser + toothpaste group (LT). The samples in Group II-IV were treated with the respective test agents and were placed under SEM to study the changes in the dentinal tubule number and diameter. The data obtained from SEM were then subjected to statistical analysis using an unpaired t-test. Results The unpaired t-test revealed extreme statistical differences in means between the test and the control groups and among the test groups (p<0.0001). The results we obtained within the scope of this study showed that both the ErYAG laser (1.3 W, 100 mJ, 3 Hz, 60 s twice) and dentifrice containing 8% arginine-calcium carbonate as the main ingredient can significantly reduce the number and diameter of the open dentinal tubules. Conclusion Our findings have demonstrated that both the 8% arginine-calcium carbonate technology and ErYAG laser successfully reduced the number and diameter of the open dentinal tubules and hence can be promising agents to deal with dentinal hypersensitivity in future clinical studies.
