Background Naswar is a moist, non-chewable, and smokeless tobacco product ensconced in the buccal vestibule or floor of the mouth. Consumption of naswar is very popular in South Asia, especially Pakistan. This cross-sectional study compared the periodontal clinical parameters amongst mild, moderate, and severe naswar users. Methods 318 naswar users, categorized into three equal groups (n = 106) severe naswar users, moderate naswar users, and mild naswar users were drawn for this study. Bleeding on probing, pocking depth, gingival recession, and attachment loss were assessed using the UNC-15 probe and compared among the three groups of naswar users. Data analysis was done with the help of SPSS. Statistical significance was deliberated at p value ≤0.05. Results 28.9 ± 7.6 years was the mean age presentation. The mean % of bleeding on probing score was 61.95% in severe naswar users, 56.62% in moderate naswar users, and 51.23% in mild naswar users with a p-value of 0.001*. In severe, moderate, and mild naswar users the probing pocket depth (4-6mm) were 35.14%, 30.95%, and 23.21% respectively. 26.78% severe naswar users were having mean percentage for probing pocket depth (>6m) followed by moderate naswar users (17.26%) and mild naswar users (17.26%) with a significant p-value (0.001*). Clinical attachment loss (CAL) was 2.50 percent in light naswar users, 3.0 percent in moderate naswar users, and 4.25 percent in severe naswar users. Clinical attachment loss (CAL) was 2.50 percent in light naswar users, 3.0 percent in moderate naswar users, and 4.25 percent in severe naswar users. Severe naswar users had a high mean percentage of gingival recession (23.21%), whereas light 13.67 percent and moderate 14.88 percent naswar users had a smaller difference. Conclusions Clinical periodontal parameters were more worsen in heavy naswar users compared to moderate and light naswar users.

Aim: To find out the effect of dentifrice containing 8% strontium acetate and 8% arginine in reducing dentinal hypersensitivity. Study Design: Randomized clinical trial Place and Duration of Study: Department of Periodontology, Gandhara University Peshawar from 1st June 2014 to 31st October 2021. Methodology: Six hundred and twenty five patients were enrolled. The study was conducted in Sardar Begum Dental Hospital, Gandhara University Peshawar. They were divided into two groups; Group A were using dentifrice that contains 1450ppm sodium monofluorophosphate and 8.0% arginine whereas patients of group B were given dentifrice which contains 1040 ppm fluoride as sodium fluoride and 8% strontium acetate. Results: The mean difference was 0.59 of the initial less than one min Schiff values in both the groups. On the other hand, Schiff values in both the groups after 8 week application was 0.26. Likewise, difference in baseline mean values was 2.32 while 1 min post-application mean difference for strontium acetate and arginine was 7.13 and 2.88 respectively. Conclusion: Significant decreased in hypersensitivity in patient using the arginine and strontium acetate. Therefore it was an effective dentifrices in decreasing in office hypersensitivity.
