摘要
目的研究脉冲Nd-YAG激光辐照乳牙的临床防龋作用,并与传统的氟化物窝沟封闭法比较。方法选择2~3.5岁需进行防龋治疗、家长同意的29名儿童作为受试者,将其无龋坏的上下颌第一乳磨牙,第二乳磨牙共119颗牙作为研究对象,实验组的两侧同名牙分为左侧激光组,右侧窝沟封闭组。激光组接受脉冲Nd-YAG激光辐照,窝沟封闭组涂以3M窝沟封闭剂,对照组不做任何处理。12个月后复查,对各组龋面均进行对比分析。结果激光组与窝沟封闭组差异无统计学意义(P〉0.05),激光组与空白对照组差异有统计学意义(P〈0.05),窝沟封闭组与空白对照组差异有统计学意义(P〈0.05)。结论脉冲Nd-YAG激光辐照乳牙用于临床防龋,能有效提高乳牙防龋能力,使用方便,疗效好,具有良好的临床应用前景。
Objective To study the caries prevention of the pulse Nd-YAG laser irradiation on deciduous teeth and make a comparison with the traditional method of fluoride fissure sealantMethods 29 children of 2-3.5 years age who needs preventative treatment with dental caries were chosen with the consent of their parents.The first and the second caries-free molar teeth were investigated as the research object,take the right side as the fissure sealant group,and the left side as laser group.Laser group received Nd-YAG pulse laser irradiation,and fissure sealant group were coated with 3 M fissure sealant agent,and the control group received nothing.After 12 months all teeth were evaluated to study teeth surface caries.Results The comparison between the three groups show that there was no significant difference(P〈0.05) between laser group and fissure sealant group,there were statistical differences between laser group and control group(P〈0.05) and statistical differences between fissure sealant group and control group(P〈0.05).Conclusion It can effectively enhance the preventability of deciduous teeth caries that pulse Nd-YAG laser irradiation deciduous teeth was used for clinical prevention,which has good prospect of clinical application owe to jt's convenience and better effect.
