The patient was 20 years old, mentally retarded, and suffered from chronic seizures. Some teeth required scaling and filling, and gingivectomy and gingivoplasty for gingival overgrowth in the distal area of the mandible were also necessary. General anesthesia was used for this patient because the routine treatment was impossible for her with these medical problems. After scaling and filling of two teeth, gingivectomy was done with a scalpel in order to reduce the time of anesthesia; then Nd:YAG laser was used to reshape the gingiva and control bleeding. As the patient was mentally retarded and had chronic seizures, bleeding control was very important.
