Patients with Pyogenic Granuloma Treated with Ho Laser:a Clinical Analysis of Its Efficiency

Objective To investigate the clinical efficiency and side-effect in the patients with pyogenic granuloma treated with Ho laser.Methods Totally 141 cases were randomly assigned to group one treated by Ho laser(n=71) and a control group cooled by liquid nitrogen (n=70) . The clinical efficiency and side-effect were observed.Results Totally 68 cases in the Ho laser trial were satisfactorily cured in the first time,and 46 cases in the trial cooled by liquid nitrogen were satisfactorily cured.It was 3 percent of side-effect observed in the Ho laser trial,and 16 percent of side-effect observed in the liquid nitrogen trial. There were statistically significant differences of effectiveness rate between these two treatment methods (χ~2=20.57,P0.001),and side-effect(χ~2=7.01,P=0.008).Conclusions It is better in the patients with pyogenic granuloma treated with Ho laser than cooled by liquid nitrogen in the clinical efficiency and lower side-effect.
