摘要/Abstract

摘要： ［摘要］目的通过手术方法预防下颌角截骨手术后下颌软组织松垂，观察手术效果，探讨更有效的手术方式。方法对18例下颌角方大患者同期行下颌角截骨术及颏下颌下颈阔肌成形术，纠正患者下颌角方大及预防颏下颌下脂肪堆积、松垂。结果所有患者术后随访半年至2年，无1例面神经下颌缘支损伤致下唇歪斜；所有患者张口度正常；术后16例患者对术后外形比较满意；1例患者术后感染后取出提升线；1例患者颏下颌下仍较肥厚松垂，效果不明显。结论颏下颌下颈阔肌成形术在下颌角截骨术中同期施行对下颌角方大患者面部轮廓改善效果良好，安全可靠，同时面部神经血管丰富，术者应熟悉其分布走行，重视钝性分离，不断积累手术经验及操作技巧才能达到满意的手术效果。

Abstract: Abstract： Objective To assess the effectiveness of a ACPCPP containing new product in reducing enamel demineralizationon post orthodontic patients.Methods The study design was doubleblind,randomized clinical trial .63 subjects with enamel decalcification（not cavitated）on their upper teeth（14～24，or 15～25）were selected and randomly divided into two groups:the experimental group （31 cases）and the control group （32 cases）.The experimental group used GC Mousse while control group used placebo mousse （without CCPACP）once a day at night after brushing with fluoride dentifrice.The Enamel Decalcification Index（EDI）was used to determine the extent/severity of white enamel demineralizationat baseline,1 month and 3 months after treatment.A oneway analysis of variance （ANOVA）was done with STATA 12.0 software packagefor the average enamel decalcification index scores.Results 58 subjects completed the trial,with 28 in the experimental group and 30 in the control group.Baseline,1 month,3 months EDI of the experimental group were（0.5903±0.2585）,（0.4514±0.2077）,（0.2396±0.1499）,respectively; and those for the control group were （0.5291±0.2494）,（0.4397±0.2068）,（0.3287±0.1757）,respectively.The difference between the experimental group and control group was statistically significant 3 months after treatment.Conclusions The application of CPPACP can help reducing the number/extent of white spot lesions already present after fixed orthodontic treatment.
