Effectiveness of Single versus Multiple Visits for Endodontic Treatment of Permanent Teeth: Meta-analysis

Abstract

Objective: To investigate whether therapeutic efficacy of single visit root canal treatment, when compared to multiple visits root canal treatment for permanent teeth, has no significant different outcome of healing rate.

Methods: PubMed database was systematically searched on clinical trials together with searching in Biomed Central, Open Access, Google scholar. They were all filtered for English articles from 1990 until 2012. The included studies were randomized controlled clinical trials comparing healing rates of single and multiple visit root canal treatment. The healing rates were evaluated by clinical characteristics and radiographic interpretation. Data in those studies were extracted and analysed using stata 11.2 software

Results: Seven articles were included an analyzed. Difference between two treatment modalities was calculated with relative risk of 0.78 (95% CI 0.56-1.09).Due to the homogeneity of data, quantitative systematic review was undertaken by fix-effect model. The healing rates of single and multiple visits root canal treatment were 86.3% และ 83.4% respectively. Evidence suggests that single visit root canal treatment has no differences of healing rates compare to multiple visits root canal treatment.(p=0.15)

Conclusion: The healing rate between single visit root canal treatment and multiple visits root canal treatment was not statistically significant different.
