Evaluation of the clinical efficacy of potassium nitrate desensitizing mouthwash and a toothpaste in the treatment of dentinal hypersensitivity

Abstract

Potassium Nitrate has been used as a desensitizing agent to treat dentinal hypersensitivity. The effectiveness of a potassium nitrate is evaluated both in the form of a toothpaste and a mouthwash in a clinical study. Thirty patients were assessed using evaporative stimuli and thermal stimuli and response was evaluated using Visual Analogue Scale at baseline, at 2 weeks and 4 weeks. The patients were divided into. group I: fifteen patients who used toothpaste containing 5% potassium nitrate, sodium fluoride, xylitol and triclosan, group II: Fifteen patients who used mouthwash containing 3% potassium nitrate, sodium fluoride, xylitol and triclosan . The results of both the assessment methods indicated that potassium nitrate toothpaste as well as mouthwash showed statistically significant decrease in the sensitivity score on a Visual Analogue Scale. This was effective in reducing the symptoms of dentinal hypersensitivity when used either as toothpaste or as a mouthwash. But, there were no statistically significant differences between the groups, although both were effective in the treatment of hypersensitivity. Key words:Dentinal hypersensitivity, potassium nitrate toothpaste, potassium nitrate mouthwash, desensitizing agents.

Efficacy of a 3% potassium nitrate mouthrinse for the relief of dentinal hypersensitivity

“…15,17,19 Investigators in another study reported that rinsing with a fluoridated mouthrinse containing 3% KNO 3 (adjunctive to toothbrushing with a nonfluoride toothpaste) was as effective as toothbrushing with a fluoridated toothpaste containing 5% KNO 3 in reducing sensitivity after 2 and 4 weeks of twice-daily treatment. 18 Participants in our study and the 2 earlier companion studies 20,21 were not blinded to their allocated treatment, because the comparator group did not include a placebo or control mouthrinse. Although this was a limitation of the study design, the aim in all 3 studies was to be representative of "real-world" behavior and evaluate the potential benefit of introducing a KNO 3 mouthrinse into a typical oral hygiene regimen (daily toothbrushing with fluoride toothpaste) for the relief of DH.…”

“…Although less well studied than toothpastes, the efficacy of mouthrinses containing potassium salts (2% potassium citrate, 2.4% or 3% potassium nitrate [KNO 3 ]) for the relief of DH has been investigated in randomized controlled studies. [15][16][17][18][19] Investigators reported improvements in sensitivity from baseline, with studies comparing KNO 3 mouthrinses with negative control or placebo mouthrinses also reporting significant improvements in DH versus their respective controls. 15,17,19 In 2 8-week studies, we reported on the results of twice-daily use of a newly developed 3% KNO 3 mouthrinse, adjunctive to toothbrushing with a regular fluoride toothpaste, in participants with DH.…”

Clinical Evaluation of Nano-Hydroxyapatite as Dentin Desensitizer

“…The subjective assessment of dentin hypersensitivity was done before application of the agent (baseline) then immediate after treatment, 1day, 1 week, 2weeks and 4 weeks respectively. The patients were educated to rate their perception to tactile, air and cold stimuli by using the VRS (11) .…”

Uso Do Nitrato De Potássio No Tratamento Da Hipersensibilidade Dentinária: Uma Revisão De Literatura

“…As mais diversas formas de tratar a hipersensibilidade dentinária visam a ou reduzir a excitabilidade das fibras nervosas dentro do órgão pulpar ou obstruir os túbulos dentinários abertos. Dentre os diversos agentes que têm sido utilizados como dessensibilizantes, aqueles que continham íons potássio se mostraram eficazes no combate dessa problemática (SHARMA et al, 2012;JAMES et al, 2017). O Nitrato de Potássio sozinho ou associado com outro tratamento é amplamente recomendado na prática clínica odontológica (JAMES et al, 2017).…”
