OBJECTIVE: The objective of this study was to compare the efficacy of dentifrices containing potassium nitrate and strontium chloride in reducing dentinal sensitivity pain. METHODOLOGY: A pilot study was conducted in Islamic International Dental Hospital Islamabad, Pakistan (Duration two weeks). Forty participants were selected, aged between 18-40 years, having dentin hypersensitivity with the minimum score of 4 on Visual Analog Scale. Participants were randomly allocated with dentifrices containing 5% w/w potassium nitrate and 10 % w/w strontium chloride and were asked to use it for 2 weeks and come back for follow up. Statistically significant correlations were found using the Man Whitney test. A pre-designed proforma was used to acquire information about the patient. Sensitivity was determined with the aid of the Visual Analog Scale. RESULTS: There was greater reduction in moderate pain from 85.8% to 71.4% with strontium chloride and from 84.2% to 79% with potassium nitrate. CONCLUSION: 10 % w/w strontium chloride is more effective than the 5% w/w potassium nitrate for the management of dentin hypersensitivity. KEYWORDS: Toothpastes, Sensitivity, Strontium Chloride, Potassium Nitrate HOW TO CITE: Kiani AZ, Hassan S, Rafiq T. Clinical comparison of 5% potassium nitrate and 10% strontium chloride toothpastes in alleviating dentin hypersensitivity following manual scaling: A pilot study. J Pak Dent Assoc 2021;30(1): 56-60.

Background: Diabetes type 2 and periodontitis has bi-directional relationship not only diabetes is a risk factor for periodontitis but periodontitis could have negative effect on glycemic control. Poor glycemic control is associated with reduced salivary pH. Aim: To compare the difference in salivary PH in patients with Periodontitis with or without Diabetes mellitus (Type 2). Method: A total of 348 consenting subjects were recruited for this investigation. There were 116 with diabetes mellitus and periodontitis, 116 with periodontitis but not diabetes and 116 patients with no periodontitis and diabetes. Salivary PH strips were used to determine the PH levels in each participant and recorded. Results: Participants with periodontitis and diabetes had decreased salivary PH of 6.16 ± 0.03 when compared with individuals with periodontitis who were not diabetic who had PH of 6.62 ± 0.04. The mean salivary PH was compared between the three groups (Control, Periodontitis and DM) where a statistically significant relationship was determined (P<0.05). Conclusion: Our study concluded that the salivary PH of patients with DM and periodontitis is lower than that of the control group. The difference in mean PH value between group 1, group 2 and group3 was statistically significant (P<0.05). Keywords: Periodontitis, Diabetes mellitus, salivary PH
