COMPARISON OF EFFICACY OF NANOHYDROXYAPATITE DESENSITIZER, ND:YAG LASER AND THEIR COMBINED EFFECT IN THE TREATMENT OF DENTIN HYPERSENSITIVITY: A CLINICAL STUDY

Dr. Ashtha Arya, Dr. Anshul Arora

Abstract


There are various options for the treatment of dentin hypersensitivity; however, superiority of one modality over others alone has not been currently
proven.
Methodology: The study was conducted on 90 teeth with dentin hypersensitivity assessed by tactile and cold air stimuli measured by visual analog
scale (VAS). Teeth were randomly divided into three groups, G1 (n=30) treated by Nanohydroxyapatite desensitizing paste; G2 (n=30) treated by
Nd:YAG laser and G3 (n=30) received Nd:YAG laser plus Nanohydroxyapatite desensitizing paste. The level of sensitivity was analyzed by VAS
at each control. The VAS reduction percentages were calculated and data subjected to statistical analysis.
Result: Comparing the means of responses for the three groups revealed that Nd:YAG laser group and the combination treatment group had a
higher degree of desensitization compared to group treated with only desensitizing paste.
