Beneficial effects seen with most desensitising toothpastes

Area of Science:

• Dentistry
• Pharmacology

Background:

• Dentine hypersensitivity is a common dental condition.
• Effective management strategies are crucial for patient comfort.

Purpose of the Study:

• To systematically review and meta-analyze randomized controlled trials (RCTs) on the efficacy of toothpastes for dentine hypersensitivity.
• To identify specific ingredients with significant desensitizing effects.

Main Methods:

• Searched PubMed, Cochrane CENTRAL, and Embase databases for relevant RCTs published in English.
• Two authors independently screened studies, extracted data, and assessed risk of bias.
• Conducted a random-effects meta-analysis to calculate standardized mean differences and 95% confidence intervals.

Main Results:

• Included 31 RCTs with 2436 patients; most studies were of moderate quality.
• Meta-analysis revealed desensitizing effects for five types of toothpaste.
• Strontium-containing toothpastes demonstrated no significant difference from placebo.

Conclusions:

• Sufficient evidence supports the use of potassium-, stannous fluoride-, calcium sodium phosphosilicate-, and arginine-containing toothpastes for dentine hypersensitivity.
• These ingredients offer effective relief for sensitive teeth.
• Strontium-containing toothpastes are not recommended for dentine hypersensitivity based on current evidence.
