抄録
Our previous studies have shown that the irradiation of He-Ne laser for 2 min per day and 5 days per week inhibits the deposition of supra-gingival plaque in hamsters, which depends on bactericidal effect of the laser. In this report we examined the effect of lesser frequency of irradiation for the purpose of practical application.<BR>Laser used was SOFT LASER 632 (MAINFAR, FRANCE), with a wave length of 632.8 nm, and out put energy 6 mW (CW). Twenty four male golden hamsters were maintained in the diet #2000 and deionized water during this experiment. After four weeks these animals were divided into two groups, A and B. Group A was irradiated in the same conditions of the previous study.Group B was for 3 min once a week. The irradiation was continued for four weeks. Right mandible molars were irradiated, and left side was a non-irradiated control. After irradiation plaque deposition was recorded with periodontal chart (Johansen E., 1952) and calculated by computed digitizer.<BR>As a result, inhibitory effect of plaque deposition was observed in group B that is an irradiation of once a week. It is considered that He-Ne laser would be a useful tool for plaque control in dental practice.
