Summary: | Introduction: Dentinal Hypersensitivity (DH) is commonly
encountered clinical condition in dental practice which affects
8-57% of the adult population presenting for dental treatment,
but the treatment of the same remains doubtful.
Aim: The purpose of this study was to evaluate and compare
the effects of three different desensitizing agents (15% nano
hydroxyapatite crystals; 5% novamin and 8% proargin) on
dentinal permeability and tubule occlusion in-vitro. Scanning
Electron Microscope (SEM) was used to evaluate the effect of
these commercially available desensitizing toothpastes.
Materials and Methods: A total of 40 disc shaped dentin
specimens were dissected from extracted premolars. Dentin
discs of 1mm were obtained with the help of diamond discs.
Ten specimens were randomly selected and allocated to the
evaluation groups A (control group), B (Nano-hydroxyapatite),
C (Novamin) and D (Proargin). Each treatment group dentine
disc specimen was treated with the respective slurry for two
minutes for a period of seven days. Each disc was subjected to
a pre- and post-treatment SEM analysis to evaluate the changes
occurring in the dentinal tubules.
Results: The qualitative analysis showed no occlusion of the
dentinal tubules in Group A (control group) and Group B (nanohydroxyapatite) showed 98.1% tubule occlusion. Group C
(Novamin) and D (Proargin) showed 83.1% and 69.1% tubule
occlusion respectively. Quantitative analysis showed a statistical
significant difference between Group B and D (p< 0.005) and
no statistical significant difference between group B and C (p=
0.235). Similarly, there was no significant difference between
Group C and D as (p=0.235).
Conclusion: It was concluded that all the three desensiting
agents were effective in the dentine tubule occlusion. In
addition efficacy of nano-hydroxyapatite toothpaste was greater
compared to the other desensiting agents. |
