| 摘要 目的：探讨应用半导体激光联合酪蛋白磷酸肽钙磷复合体(CPP-ACP)对乳牙早期釉质龋再矿化的作用。方法：选择下颌离体乳前牙制备人工龋模型40例，将其随机分为5组：脱矿组(A)、单纯激光组(B)、CPP-ACP组(C)、先激光后CPP-ACP组(D)、先CPP-ACP后激光组(E)。运用X射线能谱分析技术分析五组样本的钙和磷摩尔百分比变化，运用扫描电子显微镜观察牙釉质表面形态的变化。结果：C组、D组、E组的Ca、P摩尔百分比含量明显高于A组(P＜0.05)，而D组、E组再矿化程度高于C组(P＜0.05)，B组Ca、P摩尔百分比与A组比较差异无统计学意义(P＞0.05)。扫描电镜观察显示再矿化处理后除对照组试件外，其余3组试件均可见矿物质沉积。结论：激光协同CPP-ACP能有效促进脱矿乳牙的再矿化，其再矿化能力远大于单纯使用CPP -ACP，单纯使用激光在本次实验中未能体现出再矿化能力。 |

| ABSTRACT Objective: To investigate the remineralization of diode Laser and CPP-ACP on the initial enamel caries on primary teeth. Methods: A total of 40 samples of retained mandibular primary central incisors were collected, building artificial enamel caries le- sions and randomly divided into five groups: control group(A), DiodeLaser group(B), CPP-ACP group(C), Diode Laser first and E CPP-ACP later group(D), CPP-ACP first and DiodeLaser later group(E). The Mole percentage of each sample was evaluated using energy dispersive X-ray analysis, performed from the five groups. We use scanning electoron microscope to observe the enamel surface structural changes. Results: After remineralization, the Mole percentage of C, D, E group were higher than A group(P＜0.05), the D, E group was higher than C group(P＜0.05). A and B group have no statistical significance(P＞0.05). The mineral deposit was observed by the scan- ning electron microscope in samples of three groups after remineralization, except samples of the control group. Conclusion: Diode Laser cooperate with CPP-ACP promote the remineralization of initial enamel caries on primary teeth，but the remineralization ability is better to CPP-ACP group. Besides, DiodeLaser group demonstrate no abilit of remineralization in this research. |
