Abstract
Aim: This study aimed to assess the desensitizing efficacy of commercially available cow milk compared to potassium nitrate (KNO3) mouthwash and warm saline rinses after nonsurgical periodontal treatment.Materials and Methods: A randomized controlled trial was conducted in the Department of Public Health Dentistry of a dental college from August 21, 2018 to September 10, 2018. A total of 75 patients who reported hypersensitivity after scaling and root planing (SRP) were recruited and randomly assigned into three groups: cow milk (I), KNO3 mouthwash (II), and warm saline rinses (III). Dentine hypersensitivity (DH) was assessed at six time points using the verbal rating scale (VRS) for thermal stimuli and visual analog scale (VAS) for air blast and thermal stimuli. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 21 (IBM Corp., Armonk, NY). Mean reduction in DH in each group was measured using non-parametric tests.Results: Patients in all the three groups were found to be comparable with respect to baseline characteristics. Mean reduction in VRS and VAS scores for DH in milk and KNO3 mouthwash was found to be significantly high as compared to warm saline rinses group.Conclusion: From the results, cow milk was found to be equivalent in efficacy as compared with KNO3 mouthwash but superior to warm saline rinses in treating DH post-SRP.
Highlights
Scaling and root planing (SRP) is the mainstay of nonsurgical periodontal therapy that aids in the effective removal of bacterial deposits from the tooth surface
Mean reduction in verbal rating scale (VRS) and visual analog scale (VAS) scores for Dentine hypersensitivity (DH) in milk and KNO3 mouthwash was found to be significantly high as compared to warm saline rinses group
Mean periodontal probing depth (PPD) score at baseline was found to be significantly lower in group III as compared to group I and group II
Summary
Scaling and root planing (SRP) is the mainstay of nonsurgical periodontal therapy that aids in the effective removal of bacterial deposits from the tooth surface. It prevents the initiation or progression of gingival and periodontal diseases [1]. It is often accompanied by several undesirable side effects such as gingival recession and exposure of root dentin due to the removal of cementum. It leads to increased sensitivity to external stimuli This condition, when gets severe, has been termed as dentin hypersensitivity (DH), dentin sensitivity or root dentin sensitivity, or cervical dentin sensitivity in literature [3]
