The effects of calcium hydroxide in the treatment of immature permanent tooth pulp infection / 实用口腔医学杂志

ABSTRACT

Objective: To evaluate the effects of calcium hydroxide [Ca(OH)2]in the treatment of immature permanent tooth pulp infection. Methods: 36 immature permanent teeth with pulp necrosis or periapical periodontitis were randomly divided into 2 groups (n = 18). The teeth in experimental group were treated with [Ca(OH)2]and in control group with triple antibiotic paste ciprofloxacin + metronidazole + minocycline(TAP). Then the periapical condition and root growth were evaluated by clinical follow up and Xray examination. Follow-up was conducted at 3rd, 6th, 12th, 18th and 24th month after operation. Results: The roots of 10 teeth were developed and 8 teeth apical foramen were reduced in experimental group. The roots of 13 teeth were developed and 5 teeth apical foramen were reduced in control group. There is no statistic difference between the groups. Conclusion: Calcium hydroxide is as effective as TAP in the treatment of immature permanent tooth pulp infection.
