Abstract:
BACKGROUND: Vitapex is an injectable root canal filling material. It possesses effects of antibiosis, analgesia, as well as promotes formation of alveolar bone, dentin and cementum, which had been widely used in apexification. However, it also has weakness of long induction time and need reduplicated subsequent visit.OBJECTIVE: To explore the therapeutic effect of mineral trioxide aggregate (MTA) and Vitapex paste on apexification.DESIGN, TIME AND SETTING: The contrast observation experiment was performed at the Department of Stomatology,Shenyang Children's Hospital from February 2006 to November 2008.PARTICIPANTS: A total of 42 patients with 49 teeth were included in this study, including 28 anterior maxilla and 21 premolars.The X-ray film showed that the root tip of teeth was immature.METHODS: The teeth were randomly divided into the experimental group (n=25) and control group (n=24), which was apexificated by MTA and Vitapex paste, respectively.MAIN OUTCOME MEASURES: The effective rate of two groups was compared at months 3, 6 and 12 after operation.RESULTS: All teeth were included in the final analysis. The effective rate of experimental group was greater than the control group at 3 months after operation, and the difference had significant (P < 0.05), while, the effective rate was similar in two groups at 6 and 12 months after operation (P > 0.05).CONCLUSION: Both MTA and Vitapex paste are ideal filling materials in apexfication. Nevertheless, MTA may be a substitute in apexfication for its short therapy duration and precisely therapeutic effect.
