OBJECTIVES
Fluoride therapy is important for control and prevention of dental caries. Laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. The objective of this study was to compare the effects of CO2 and diode lasers on enamel fluoride uptake in primary teeth.
MATERIALS AND METHODS
Forty human primary molars were randomly assigned to four groups (n=10). The roots were removed and the crowns were sectioned mesiodistally into buccal and lingual halves as the experimental and control groups. All samples were treated with 5% sodium fluoride (NaF) varnish. The experimental samples in the four groups were irradiated with 5 or 7W diode or 1 or 2W CO2 laser for 15 seconds and were compared with the controls in terms of fluoride uptake, which was determined using an ion selective electrode after acid dissolution of the specimens. Data were analyzed by SPSS version 16 using ANOVA treating the control measurements as covariates.
RESULTS
The estimated amount of fluoride uptake was 59.5± 16.31 ppm, 66.5± 14.9 ppm, 78.6± 12.43 ppm and 90.4± 11.51 ppm for 5W and 7 W diode and 1W and 2 W CO2 lasers, respectively, which were significantly greater than the values in the conventional topical fluoridation group (P<0.005). There were no significant differences between 7W diode laser and 1W CO2 laser, 5W and 7W diode laser, or 1W and 2W CO2 laser in this regard.
CONCLUSION
The results showed that enamel surface irradiation by CO2 and diode lasers increases the fluoride uptake.
目的
氟化物治疗对于控制和预防龋齿很重要。激光照射可以增加氟摄取量，尤其是与局部应用氟化物联合使用时。本研究的目的是比较二氧化碳激光和二极管激光对乳牙牙釉质氟摄取的影响。
材料与方法
40颗人乳牙随机分为四组（n = 10）。去除牙根，将牙冠近远中向切成颊侧和舌侧两半作为实验组和对照组。所有样本均用5%氟化钠（NaF） varnish处理。四组中的实验组样本分别用5或7W二极管激光或1或2W二氧化碳激光照射15秒，并在氟摄取方面与对照组进行比较，氟摄取量在标本酸溶解后使用离子选择性电极测定。数据用SPSS 16版软件进行分析，将对照测量值作为协变量采用方差分析。
结果
5W和7W二极管激光以及1W和2W二氧化碳激光的估计氟摄取量分别为59.5±16.31 ppm、66.5±14.9 ppm、78.6±12.43 ppm和90.4±11.51 ppm，这些值显著高于传统局部氟化组（P<0.005）。在这方面，7W二极管激光与1W二氧化碳激光、5W和7W二极管激光或1W和2W二氧化碳激光之间没有显著差异。
结论
结果表明，二氧化碳激光和二极管激光对牙釉质表面的照射可增加氟摄取量。
