Objective To investigate the treatment mechanism, irradiation power, method and difference of curative effect of argon ion laser for oral precancerous lesions. Methods 53 cases of oral leukoplakia and lichen planus were treated with Ar ~ + laser, and the clinical changes of patients before and after treatment were compared. Results Oral leukoplakia was cured in 31 cases and the cure rate was 100%. Oral lichen planus in 22 cases was cured in 13 cases, markedly effective in 7 cases and ineffective in 2 cases. The effective rate was 90.9% and the total effective rate was 96.2%. Conclusion Argon ion laser treatment of chronic oral lesions such as oral leukoplakia and lichen planus is not only effective, easy to operate, less complications and light, and has a positive effect on the prevention of cancer. It is worthy of clinical treatment.
