Abstract

Abstract: Objective: To explore the clinical effects of NiTi rotary instruments and manual stainless steel instruments in root canal therapy of primary molars. Methods: Ninety children (90 teeth) who received root canal therapy in their mandibular primary second molars in the Department of Pediatric Dentistry, Shenyang Children’s Hospital, from January 2016 to January 2018 were selected. The primary molars were randomly divided into two groups, the experimental group and the control group, with 45 molars in each group. ProTaper NiTi Rotary instruments were used in the experimental group and manual stainless steel K-files were used in the control group. The time of root canal preparation, the quality of root filling, and the pain after preparation were compared. Results: In contrast to control group, the experimental group had shorter root canal preparation time, higher root canal filling rate, and lower incidence of pain after root canal preparation (P<0.05). Conclusion: The clinical application of ProTaper NiTi Rotary instruments in primary molar root canal therapy is worth of recommendation.

Key words: NiTi rotary instrument, Primary molar, Root canal therapy
