Effects of Three Desensitizing Agents and Erbium-Doped Yttrium Aluminum Garnet Laser on Dentinal Tubule Occlusion: An In-Vitro Study.
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2017, Vol 2, Issue 6
Abstract
Objectives: To quantitatively evaluate the effects of two traditional desensitizing agents [5% sodium fluoride (Duraphat fluoride varnish), 5% glutaraldehyde-35% hydroxyethyl methacrylate (Gluma desensitizer)], an effective new agent [8% arginine and calcium carbonate-containing desensitizing paste (Pro-Argin)], and erbium-doped yttrium aluminum garnet (Er:YAG) laser on dentinal tubule occlusion by scanning electron microscopy (SEM). Materials and Methods: A total of fifty dentin specimens were obtained from freshly extracted, non-caries, sound human third molars and randomly divided into five groups (n = 10): Group 1: Control (No treatment), Group 2: Duraphat Fluoride Varnish, Group 3: Pro-Argin Desensitizing Paste, Group 4: Gluma Desensitizer, Group 5: Er:YAG laser. All specimens evaluated under the SEM and 10 photographs were taken from each sample at 2000× magnification. The number of open, partially occluded, and visible (open + partially occluded) dentinal tubules in each photograph was calculated. SPSS (Statistical package for the social sciences) 21.0 software was used for statistical analysis. The data were analyzed by One-way ANOVA, Dunnett C, and Tukey tests. The significant value for all tests was accepted as 0.05. Results: No significant difference was observed in the number of open, partially occluded, and visible dentinal tubules between the Pro-Argin Desensitizing Paste and Er:YAG laser groups, but fewer open, partially occluded, and visible dentinal tubules were observed in these groups than in the other groups. That is, Er:YAG laser and Pro-Argin Desensitizing Paste groups showed significantly more tubule occlusion than the other groups (p < 0.05). Conclusions: Er:YAG laser and Pro-Argin Desensitizing Paste groups were found to be more effective than the other groups in occluding the dentinal tubules.
