Pak Oral Dental J Jan ;39(3):273-6.

The objective of the study was to determine an improvement in cervical dentin hypersensitivity at 4 weeks of application of fluoride varnish from baseline observation .This descriptive observational study was carried out in department of Operative Dentistry, Rawal Institute of Health Sciences, Islamabad, from 1st July 2017 to 31st December 2017 .After approval by ethical committee of the college, patients consent was also obtained. Seventy patients with hypersensitivity complain in permanent teeth with age group 20-80 years were selected. Patients data was collected through consecutive sampling consisted of 29 (41.4%) males and 41(58.6%) females with a mean age of 39.13 ±12.19.Baseline hypersensitivity scores were recorded according to Schiff scale and tooth with highest sensitivity score was selected for fluoride application testing. Improvement in scores was recorded after 4 weeks according to patient responses. Data were analyzed by SPSS version 20. Frequency and percentages were calculated for gender, type of tooth, arch involved. Mean±Standard deviation was calculated for age (20-80 years). The mean and median scores at baseline and 4-weeks-follow-up for participants in response to air stimuli with Schiff 4- point scale were calculated. Paired sample T test was applied to evaluate if statistically significant difference exist between hypersensitivity value before varnish application and 4 weeks after its application. A significant difference in sensitivity was found at 4-weeks follow-up and base line levels.
