Study on 632 nm He-Ne laser therapy on pericoronitis / 国际生物医学工程杂志

ABSTRACT

Objective To investigate the effects of He-Ne laser on the treatment of pericoronitis.Methods 75 clinical patients with pericoronitis were randomly divided into the experimental group and control group.Local conventional therapy was given to the two groups.The experimental group was given routine treatment with He-Ne laser local exposure for 15 minutes every day,while the control group took no other treatment.3 days and 7 days later,pain and inflammation degree were recorded by three-degree pain scoring method.Total treatment effects were evaluated under a comprehensive clinical treatment standard.Results After 3 days' treatment,78.9％ patients in the experimental group and 51.4％ patients in control group felt their pain disappeared.After 7 days' treatment,97.4％ patients in experimental group and 91.9％ patients in control group felt their pain disappeared.Treatment comprehensive evaluation showed that there were statistical significance differences between two groups (P＜0.05).Conclusion He-Ne laser treatment of pericoronitis has significant anti-inflammatory analgesic effect.
