説明
Caries removal by laser has the problem that the treatment time of caries removal is longer than that of conventional methods. This study investigated whether the treatment time of caries removal would be reduced by using an Er:YAG laser in combination with a prototype caries removal reagent, and also whether it would be affected the composite resin filling. <br>Thirty human extracted teeth with caries on adjacent surfaces were used; on ten of them, different caries removal methods were attempted on the left and right sides at the center of the cavity surface. <br>The left side was subjected to irradiation without caries removal reagent, and the right side was irradiated by Er:YAG laser after reagent application. Laser irradiation was performed at output powers of 80mJ or 100mJ for five teeth each. After caries removal was completed, the time required for treatment was measured, and the cavity surface was observed with a stereomicroscope and scanning electron microscope (SEM). The remaining 20specimens were classified into four groups of five teeth each according to whether reagent was used or not and the difference of laser power (80mJ or 100mJ). These experiment groups were subjected to composite resin filling after caries removal and then underwent the marginal leakage test. <br>There were no problems or significant differences for those cavity surfaces, regardless of whether reagent was used or differences in irradiation power. The treatment time was shortened by using the reagent at the laser irradiation power of both 80mJ and 100mJ. It is considered that the reagent enhanced the softening of the carious dentin, then facilitated the caries removal by laser. <br>In the results of the marginal leakage test, no significant leakage was observed in any group. Based on the above, it can be inferred that the use of a caries removal reagent in combination with the Er:YAG laser is effective for removing dental caries.
