Abstract

Abstract:

BACKGROUND: Great achievements of calcium hydroxide which is used to induce the apical seal have been reported.
OBJECTIVE: To evaluate the differences in clinical efficacy of apexification with four kinds of calcium hydroxide preparations.
METHODS: Totally 127 patients with periapical lesions for abnormal central cusp were selected and underwent the apexification respectively with the Vitapex (n=31), the Metapex (n=32), the calcium hydroxide cataplasm (n=34) and the calcium hydroxide powder (n=30). X-ray observation of the tooth apex was made at 1, 3, 6, 12 and 24 months after operation.
RESULTS AND CONCLUSION: (1) Induction cycle: There was a significant difference between groups (P < 0.001), except for the Vitapex group and Metapex group. (2) Induction effect: The success rates in three groups of Vitapex, Metapex and calcium hydroxide cataplasm were higher than that in the group of calcium hydroxide powder (P < 0.05), but there was no significant difference between the first three groups. There was a good root induction in three groups of Vitapex, Metapex and calcium hydroxide cataplasm, and the induction cycle was shorter in Vitapex and Metapex groups.
