Electrotome is frequently used for surgical treatments in the field of dentistry and oral surgery. We report a rare case of gingival and alveolar bone necrosis caused after gingivectomy with electrotome. The patient was a 30-year-old female complained of gingival discolor. She noticed the gingival discoloration 2 days after the gingivectomy with electrotome by her family dentist. The gingiva around the left upper central incisor was changed to white in color. Nine days after the electrosurgery, the left upper central incisor fell off spontaneously, and 7 weeks after the electrosurgery, the sequester was removed. Epithelization was completed 2 weeks after the sequestrectomy, and she was successufully treated by the fixed bridge and removable artificial gingiva.

Psoriasis is a chronic dermatitis of undetermined etiology. The patient was a 60-year-old male who complained of pus discharge from maxillary frontal gingiva. The patient had been suffered from psoriasis vulgaris for 8 years, and there were many reddish papules in breast, abdomen, limbs and facial skin. Radiological examination showed a lowered maxillary left canine, periapical radiolucency of the maxillary right first premolar and horizontal loss of alveolar bone in maxilla and mandibular bone. After treatment of marginal periodontitis, the maxillary right first premolar and the impacted maxillary left canine were extracted. After these treatments, reddish papules rapidly improved and disappeared completely within 2 weeks after extraction. This clinical course suggests that psoriasis was caused by dental focal infection.

Four cases of brain lesions which developed symptoms in the region of mouth and jaw are reported. Lesions of three cases were brain tumors, which were acoustic neurinoma, lipoma, meningioma, and cerebral infarction. Symptoms of the mouth and jaw were consciousness of tongue and lip, trigeminal neuralgia, spontaneous pain of eye and maxilla. We are not well-versed in these illnesses. This paper describes the relation of such illnesses with symptoms in the region of the mouth and jaw.As mentioned above, when neuralgia and consciousness of oral mucosa and face are found in patients, we should consider the possibility of brain lesions.

The purpose of this study was to investigate the postoperative one-year positional change following Intraoral Vertical Ramus Osteotomy (IVRO). Retrospective radiographic assessments were performed on 43 patients who underwent bilateral IVRO to setback without interosseous fixation.The results were as follows:1. No relationship was observed between the openbite and the mandibular displacement during postoperative treatment for one year. In addition, no relationship was observed between the amount of mandibular displacement following surgery and that during postoperative treatment for one year.2. The postoperative mandibular position following IVRO was stable, and this method was effective to correct mandibular protrusion.

The clinical efficacy of long-term roxithromycin (RXM) treatment was examined objectively in 8 patients with chronic diffuse sclerosing mandibular osteomyelitis. RXM was administered orally at a dose of 300mg per day for 68 days to 66 months.As a result, the results of 7 out of 8 cases (87.5%) were assessed effective, and the symptoms had disappeared in 1 to 12 months. One case assessed poor had several operations and various kinds of antibiotic therapy for more than 11 years before this therapy. In 7 cases assessed effective, the improvement of osteolytic changes on X-ray was observed. However, most of the X-ray findings remained osteosclerosis or the osteosclerosis became more predominant, when this therapy was terminated. It was considered that X-ray findings would take a long time to be normalized. Therefore, the optimum duration of administration which is the time to terminate this therapy should be decided according to the improvement of symptoms along with the disappearance of osteolytic findings on X-ray. Diarrhea and stomach discomfort in 1 case, and liver dysfunction in 1 case were found, however, these side effects were slight.The mechanisms of RXM are unclear however, these results indicate that long-term RXM treatment has therapeutic possibilities for diffuse sclerosing mandibular osteomyelitis and should be used as the first choice followed by surgical treatment if necessary.

Abstract: Cresol is commonly used in homes and hospitals as a disinfectant. In dentistry, formocresol (FC) is often used for infectious root canal therapy. Too much cresol ingestion causes severe systemic failure. An autopsy of fatal cresol poisoning is described.Case report: A 23-year-old Japanese female was admitted to ICU of Tohoku University Medical Hospital with a history that she had taken up to 100 ml of cresol soap solution 4 hours earlier. On arrival, she was semiconscious with cresol breathodor, 32.5°C body temperature and 75/50 mmHg blood pressure. Gastric lavage was not performed because of severe esophageal edema. She died after blood plasma transfusion, hemodialysis and blood filtering performed for about 60 hours. Post-mortem examination demonstrated 1) digestive tract failure: necrotizing inflammation of oro-pharynx, larynx, esophagus and stomach, 2) respiratory tract failure: sputum in trachea and bronchi, edema and hemorrhage of lung, 3) hepatic failure: severe centrolobular necrosis, 4) renal failure: tubular degeneration and 5) hemorrhagic diathesis.

It has been recommended recently that patients receiving anticoagulant therapy should undergo dental extraction without discontinuation of anticoagulant drugs in consideration of the risk of thromboembolism, but the frequency of hemorrhagic complications has not been well documented. A retrospective study of 282 patients who underwent dental extraction under continuous warfarin therapy was performed.Twenty-two of the 282 patients (8.9%) showed postoperative hemorrhages: 14 of 168 (8.3%) in those receiving administration of warfarin alone, and 11 of 114 (9.6%) in those receiving administration of both warfarin and antiplatelet drugs. Most of the hemorrhages occurred within 2 days after the extraction. The rate of postoperative hemorrhage was 5.7% in those with prothrombin time International Normalized Ratio (PT-INR) of 1.49 or lower, 12.5% in those with PT-INR of 1.5-1.99, 12.8% in those with PT-INR of 2.0-2.99, and 16.7% in those with PT-INR of 3.0 or higher, although there was no significant difference between PT-INR and frequency of postoperative hemorrhage. All patients showing postoperative hemorrhage were treated successfully by local procedures such as suturing or application of cellulose oxide gauze. These findings suggest that dental extraction can be safely done without discontinuation of warfarin therapy.

Despite advances in diagnosis, antimicrobial therapy and supportive care modalities, pneumonia remains an important cause of morbidity and mortality. In recent years, changes in the healthcare system have shifted a considerable part of older patient care from hospitals to the community, and the traditional distinction between community – and hospital-acquired infections has become less clear. With this background, pneumonia occurring among outpatients in contact with the healthcare system has been termed healthcare-associated pneumonia. The impairment of airway protective reflexes, i.e., swallowing and cough reflexes, is thought to be one of the major causes of aspiration pneumonia in older people. Anaerobic bacteria are relatively frequent pathogens in pulmonary infections that are associated with aspiration and its associated complications including aspiration pneumonitis, lung abscess, necrotizing pneumonia and empyema. Treatment consists of relatively broad-spectrum antibiotics that can cover anaerobes. In cases with concurrent presence of renal impairment, single-agent therapy is recommended in this specific patient population. In addition, since sitafloxacin has wide-spectrum antibacterial activity against pathogens isolated from patients with aspiration pneumonia, sitafloxacin could be used for the treatment of healthcare-associated pneumonia. To prevent aspiration pneumonia in elderly patients, oral care is very important, and periodical inoculation of the Streptococcus pneumoniae vaccine as well as the influenza vaccine is recommended.

Many surgical procedures for macrostomia had been advocated in past literatures, but it is hard to obtain the ideal commissure form. In this paper, 6 cases of unilateral macrostomia treated at our clinic are reported and the availability of the minor triangular flap on vermillion border in commissuroplasty is discussed.<BR>Five cases underwent new commissuroplasty using the minor triangular flap at vermillion border (Matsuya's procedure) and 1 case without it. In the latter case, deformation of the commissure form caused by postoperative scar contracture was found, though the good form was found during the post-operative period. In all cases using Matsuya's procedure, the good commissure form was made and maintained throughout the growth period. The minor triangular flap on vermillion border was considered to be useful to prevent the influence of postoperative scar contracture on the commissure form

To study the influence of Parotin (salivary gland hormone) upon wound healing, the same size of back skin was removed respectively from 6 groups of rabbits and the area of each wound was measured from day to day with following histological examinations, in comparison between the Parotin injected groups and the non-injected control group. Parotin was injected 0.1 mg./Kg. daily to the 1 st group, 0.2 mg./Kg. daily to the 2 nd group, 0.3 mg./Kg. every other day to the 3 rd, 2.5 mg./Kg. every other day to the 4 th, 0.5 mg./Kg. once a week to the 5 th. The 6 th group was not injected as control.The results were as follows.1) Wound healing was most accelerated in the group given the injection of 0.2 mg./Kg. Parotin daily.2) Histological examinations showed that in the Parotin injected group fibrougrowth of fibroblasts was more accelerated, and regeneration of capillar vessels moractive than in control.
