[A clinical observation of pericoronitis treatment with pulse semiconductor laser]

In order to valuate the effect of pericoronitis treated with pulse semiconductor laser. As a treatment group, 24 ones drawn ramdomly from 48 cases of pericoronitis were given periodontal radiation, point-radiation therapy and pharmacotherapy as well. While another 24 cases as a contrast group were given pharmacotherapy only. On the 3rd day and the 5th day the degree of pain and restriction of mouth opening of the two groups were graded, contrasted and processed by Ridit statistics. Result, The therapy group gained more notable effect in pain-relieving and mouth-opening-improving than the contrast group. Because of no damage, handy and can be done easily, be definite in curative effect, Pulse semiconductor laser treatment pericoronitis deserves popularizing.
