| 摘 要： | 应用牙本质通透性测定装置，定量测定脉冲Ｎｄ：ＹＡＧ激光在不同参数条件下照射后对牙本质通透性的影响。结果表明：在４个不同的激光参数条件下，激光照射后牙本质通透性均较照射前呈显著性下降，其中以每秒１５个脉冲０．７５Ｗ的２．０ｍｉｎ组和每秒１５个脉冲１．００Ｗ的２．０ｍｉｎ组下降最为明显，与每秒１５个脉冲０．７５Ｗ的１．５ｍｉｎ组之间呈显著性差异（ＦＫＰＦＦ＜０．０５）。提示脉冲Ｎｄ：ＹＡＧ激光在一定参数条件下照射，可熔融和封闭牙本质小管，是治疗牙齿敏感症的有效手段之一

| Abstract: | he effect of pulsed Nd:YAG laser on the permeability of non-smear layer covered human dentin was evaluated in vitro quantitatively. Four different laser parameters were used (0.75W, 15/s , 1.5min; 0.75W, 15/s, 2.0min; 1.00W, 15/s, 1.5min, 1.00W, 15/s, 2.0min). The results showed that at all the four parameters, the laser irradiation could decreased dentin permeability. When dentin lased at 0.75W,15/s, 2.0min, the dentin permeability decreased more significantly than at 0.75W, 15/s, 1.5min (FKP<0.05). It suggested that pulsed Nd:YAG laser could seal the dentinal tubules, and could be one of effective methods for dentin hypersensitivity treatment. |
