Purpose: To study the effects of two root canal filling material in the apexification.
Methods: 172 juvenile permanent teeth,including 62 teeth with pulpitis, 32 teeth with necrotic pulp and 78 teeth with periapical periodontitis, were divided into two groups.The root canal was filled with Vitapex paste and antibiotic paste.Every patient was examined once three months.The treatment lasted 6-30 months.The outcome of treatment was investigated for three years following treatment.
Results: The effective rate in the group of Vitapex paste and antibiotic paste group were 86.0% and 91.9% (P>0.05).In periapical periodontitis group,the effective rate of antibiotic paste group was significantly higher than the other (P<0.05).
Conclusion: Both Vitapex paste and antibiotics paste were good filling materials in apexification. Antibiotic paste was better than the other in periapical periodontitis group.
