摘要
我们先后用加热、激光、夜间及凝胶漂白法治疗了Ⅰ～Ⅲ度四环素牙３２０例。结果发现四种方法对不同程度染色的四环素牙的治疗，在优良率、平均治疗次数、不良反应率及回色率四个方面有不同程度的差别。加热法具有疗效较好，平均治疗次数较少的优点，不良反应率，回色率较高的缺点。激光和凝胶法具有不良反应率，回色率较低的优点，优良反应率低，治疗次数多的缺点。夜间法优良率高，就诊次数少，不良反应率，回色率低，是四种方法中最理想的方法。为临床方法的选择提供了参考依据。
Abstract cases with the various tetracycline teeth have already been treated with the four different therapeutic methods successively: thermotherapy,Laser,night teeth guarded,and gelatinous bleaching methods. The consequence demonstrates that the methods are of remarkably different results in the following respects: success rate, treated times,the rate of ill reaction,and the rate of recovered colour.Of which,the night teeth guarded vital bleaching is the best in the four respects mentioned above as the rmotherapy is better in effectiveress and fewer treated times where as higher in ill reaction and the rate of recovered colour, while laser and gelationous,better in lower ill reaction and recovered coluor but poorer in success rate and more times for treating.Authors may furnish a reference for selection of clinical methods.
