Abstract

OBJECTIVES
This study aimed to compare the efficacy of stannous fluoride toothpaste versus placebo in treating dentinal hypersensitivity.
METHODOLOGY
This quasi-experimental study was conducted at the Department of Periodontology, Rehman Medical Institute (RMI), Peshawar from July 25, 2023, to January 25, 2024. The study included 176 patients aged 18-70 years with at least two hypersensitive teeth. Participants were randomly divided into two groups: the test group (stannous fluoride toothpaste) and the control group (placebo). Sensitivity was measured at baseline, 3 minutes after application, and 15 days post-application using the Schiff Cold Air Sensitivity Scale (SCASS). Oral hygiene measures, clinical attachment loss, and gingival recession were also recorded. Data were analyzed using independent t-tests and Chi-square tests.
RESULTSThe test group showed significant improvement in SCASS scores compared to the control group (93.2% vs. 12.5%, p<0.001). Participants who used toothbrushes had significantly better outcomes than those using miswak or never engaging in oral hygiene. Participants who brushed more frequently experienced improved sensitivity relief, as effective brushing helps distribute the active fluorides uniformly across the teeth.
CONCLUSION
Stannous fluoride toothpaste significantly reduces dentinal hypersensitivity compared to placebo, supporting its use as an effective treatment for DH.
