The clinical success of different root canal treatments in primary molars

Abstract

Objectives: To examine the success rate of root canal treatment in primary molars with the use two different root canal instrumentation ways, irrigation solutions and root canal sealers. Materials and Methods: Root canal treatment was applied to 120 second primary molars of 69 children between 5-8 years old. The teeth were divided in 8 groups randomly according to instrumentation ways [conventional stainless-steel hand files / Nickel-titanium (Ni-Ti) rotary files], irrigation solutions [0.5% sodium hypochlorite (NaOCl) and 0.9% saline solution combination / 0.4% chlorhehexidine (CHX)] and root canal sealers [Zinc oxide eugenol cement (ZOE) and Apexit Plus (AP)]. All teeth were restored with stainless steel crowns. The teeth were followed 12 months both clinically and radiographically. All data was analyzed statistically by χ 2 and Wilcoxon test. Results: Statistical significance were found according to age and root canal sealers factors on success rate of root canal treatment (p0.05). The clinically and radiographically success rate of ZOE and AP were 98.3% and 68.3%, respectively. Conclusions: Root canal treatment is a successful treatment in primary molars. Ni-Ti rotary files and CHX can be a good alternative for root canal treatment in primary molars. The most effective factor to obtain clinical success of root canal treatment is properties of using root canal sealer.
