复方抗生素、氢氧化钙糊剂诱导根尖成形的临床研究

目的　探讨年轻恒牙根尖诱导成形的方法 ,评价复方抗生素、氢氧化钙糊剂在根尖诱导成形术中的临床疗效。方法　选择青少年牙髓炎或根尖周炎患者 5 6例 ,患牙 6 4颗 ,随机分为两组 ,根管预备后 ,试验组 3 8颗患牙 ,根管内先封入抗生素糊剂控制感染 ,再用氢氧化钙糊剂填入根管。对照组 2 6颗患牙 ,直接用氢氧化钙糊剂根管内封药。结果　试验组临床总有效率为 92 1 1 % ,对照组为 6 9 2 3 % ,试验组优于对照组 ,两组间有显著性差异 (P <0 0 1 )。结论　在年轻恒牙根尖诱导成形术中 ,应用复方抗生素、氢氧化钙糊剂能取得较好的疗效

A clinical study of the antibiotics complex paste and calcium hydroxide used in apcxification

Objective To investigate the method of apexification in the young permanent teeth and to evaluate the clinical result of the antibiotics complex paste and calcium hydrpxide used in the apexification.Methods 56 adolacent patients who had teeth pulpitis or periapical inflammation were selected,totally 64 teeth were included and divided into two groups at eandom.After root canal preparation of the 38 teeth in the test group,antibiottics complex paste was sealed in the canals to arrest inlection,then calcium hydroxide was filled in stead of it,while 26 teeth in the control group were directly obturated with calcium hydroxide in the canals.Results The total effective rate in the test group and control group were 92.11% and 69.23% respectively.The test group had a better result than the control group,the difference was significant(P<0.01).Conclusion The alternative use of the antibiotics complex paste and calcium hydroxide is more effective in the apexification of the young permanent teeth.
