Abstract
BACKGROUND
Dentin hypersensitivity (DH) involves sensitive symptoms, because of exposure of the dentinal tubules. Various materials have been utilized to occlude dentinal tubules for the treatment of DH. Here is a comparative evaluation of nano-carbonate apatite (n-CAP), diode laser, and their combination over the occlusion of dentinal tubules.
MATERIALS AND METHOD
Ten intact first premolars were used in this study, out of which 40 dentin disk specimens were obtained by hard tissue microtomy. Four study groups were formulated out of which one was the control group and the remaining three were test groups. Scanning electron microscopy (SEM) was done to evaluate the diameter of the dentinal tubules in each group.
RESULTS
On examining data, it was observed that the mean diameter of dentinal tubules in four study groups of control, laser, n-CAP, and n-CAP + laser was found to be 3.40, 2.00, 0.46, and 0.02 respectively. This shows the significant reduction in the diameter of dentinal tubules in the test groups when compared with the control group.
CONCLUSION
Among all the measures used to see for a reduction in the diameter of dentinal tubules, the combination group was found to be most occluding, though each of the groups also had a significant reduction in the diameter of dentinal tubules. The present study showed that combination therapy offers a promising means of treating DH in a clinical setting when compared with the treatment of DH n-CAP containing dentifrice or laser irradiation alone.
