In order to evaluate objectively the level of tension and relaxation in dental practices, the author used Biotrainer(BF-102R), one of the GSR biofeedback apparatus, to examine 119 dental outpatients on their changes of GSR due to infection, preparation, extraction and readjustment. The obtained results were as follows : 1. There were no differences in the baseline GSR between the control group and the patient groups. 2. Changes in GSR by practices were significantly larger than the baseline GSR. 3. GSR in female was larger than that in male 4. While the GSR after injection, preparation and extraction revealed lower level, the GSR after readjustment revealed higher level. 5. Most of subjects just after injection, preparation and extraction were more frequent in decrease of GSR and those just after readjustment more were frequent n increase of GSR. 6. Type 1,2(increase in skin resistance) showed greater in injection, preparation and extraction group, while type 3(decrease in skin resistance) did in readjustment group.

Extraction of an impacted third molar is one of the most frequently performed techniques in oral and maxillofacial surgery. Surgeons can suffer numerous external injuries while extracting a tooth, with percutaneous injuries to the hand being the most commonly reported. In this article, we present a case involving a percutaneous injury of the surgeon's femoral region caused by breakage of the fissure bur connected to the handpiece during extraction of the third molar. We also propose precautions to prevent such injuries and steps to be undertaken when they occur.

The purpose of the review article is to investigate the influence of periodontal diseases on preterm birth(PTB) and low birth weight(LBW). PTB and LBW are the main risk factors of infant mortality and a major public health problem. PTB is defined as delivery at less than 37 weeks and LBW is less than 2,500 grams. Over Approximately 60 percent of perinatal mortality results from PTB or LBW. Although the causes of PTB and LBW are not fully understood, infection is the leading cause of PTB and LBW. Periodontal diseases are serious disease burdens because they are caused by bacterial endotoxin, inflammatory reaction, and cytokine. The periodontal diseases are the predisposing factors of cerebrovascular and cardiovascular diseases including atherosclerosis. Over the past 15 years, previous studies revealed that periodontitis had adverse outcomes including PTB and LBW in pregnancy.

Herpes zoster (HZ) is an acute, unilateral inflammatory viral infection characterized by a rash with painful blisters in a localized area of the body. HZ is often associated with intense pain in the acute phase and presents postherpetic neuralgia in the chronic phase. During the prodromal stage of the HZ from the trigeminal nerve, however, the only presenting symptom may be odontalgia, which could be particularly difficult to diagnose. This distinctive syndrome occurs predominantly in the immunocompromised or elderly individuals. In this article, we report a case of HZ developed in the trigeminal nerve of a 60-year-old immunocompromised female patient, whose symptoms including atypical, non-odontogenic odontalgia had improved after series of antiviral treatments.

A wide variety of benign and malignant lesions and other diseases can develop on oral mucosa. Oral mucosal lesions can also be associated with an underlying systemic disease, so their correct diagnosis, which may even share similar clinical and demographic features, is always a challenge for a dentist. Common oral mucosal lesions include candidiasis, herpes viral infection, leukoplakia, recurrent aphthous stomatitis, pemphigus, lichen planus and benign migratory glossitis. The differential diagnosis of these lesions are based on a thorough review of the patient's past medical and dental history and a complete oral examination. The knowledge of clinical features such as size, location, morphology, color, and pain is helpful in establishing a diagnosis. In addition, diagnostic tests, including microbiologic and laboratory tests and biopsies are usually required for establishing a proper diagnosis.

Aplastic anemia (AA) is a blood dyscrasia characterized by hypocelluar bone marrow and peripheral blood pancytopenia. Symptomatology depends on the severity of pancytopenia. Patients with AA are susceptible to infection because of agranulocytosis. Hemorrhage caused by thrombocytopenia can be fetal to these patients. Therefore dental procedure potentially can cause serious complications and should be applied with caution. A 6-year-old boy with moderate aplastic anemia was referred to treat dental caries. General dental procedure including resin filling, preformed crown, pulpectomy and extraction was performed under sedation. Combination of modalities such as platelet transfusion, oral hygiene instruction, and dental prophylaxis was also implemented. In this report, the dental and medical management of a patient with AA was presented. Interdisciplinary care should be administered to patients with AA.

Objectives : Latex gloves hygiene is the most effective method to prevent infection of microorganisms and to reduce the incidence of cross infections. The aim of this study was to compare the bacteria reduction ratio of cleansing with water, liquid soap and alcohol gauze. Methods : The left side glove was the control group and the right side was the experimental group. The experimental group washed hand with water, soap, and alcohol gauze. The hand plate was inoculated by the hand and inoculated for 24 hours in $35^{\circ}C$. Results : Washing with water showed that CFU of control group was 1116.9 and that of experimental group was 302.8. Hand washing by water reduced 74.3% of bacteria. Liquid soap revealed that CFU of control group was 619.9 and that of experimental group was 8.3. Hand washing by liquid soap reduced 97.5% of bacteria. Alcohol gauze included 875.2 CFU in control group and 5.8 CFU in experimental group. Washing by alcohol gauze reduced 99.5% of bacteria. Conclusions : Based on the results, the most effective latex gloves cleansing method was recommended as the standardized hand washing with the liquid hand soap and alcohol gauze. The results can be used to improve training strategies for enhancing glove hygiene practice in dental clinic.

Background: The aim of this study was to understand the importance of professional oral care for inpatients by examining the type and frequency of surgery and hospital discharge period at dental hospitals, and identify the types of professional oral care actually in progress. Methods: In this study, the type of surgery and length of hospitalization were investigated among patients admitted to the dental hospital for oral and maxillofacial surgery, and the professional oral care status of inpatients who had difficulty self-managing their oral care was retrospectively identified by collecting data on oral care before and after surgery, including the type and frequency. Results: The majority of inpatients at dental hospitals were male (57.6%), elderly patients over 60 years accounted for 20% of patients, and the average length of hospitalization was 4 days. In the 20s (aged 20~29 y), the number of orthognathic surgery patients (73.1%) was high, and the incidence of cysts was high in middle-aged patients. Regarding the oral care of hospitalized patients, scaling was performed once by a dentist before surgery. After surgery, surgical dressings using H₂O₂ balls were applied and oral care education was introduced before discharge. Conclusion: Based on the results of this study, professional oral care is essential to prevent infection and complications caused by oral bacteria among inpatients at dental hospitals. It is necessary to use various oral hygiene aids for inpatients and to conduct effective oral care instruction according to each patient's situation. In addition, it is necessary to raise awareness and the role of dental hygienists in professional oral care.

Objectives : The purpose of this study was to evaluate the significance of antibiotics in reducing postoperative infection rates and other complications following third molar surgery. Patients and methods : Two groups of patients underwent surgical extraction of third molars. The antibiotics group, n=21, received a third generation cephalosporin antibiotic for 5 days, starting from the day of surgery. The non-antibiotics group, n=26, didn't receive any antibiotics and only received analgesics to control postoperative pain. Body temperature and hematologic findings including WBC, neutrophils, lymphocytes and monocytes counts were compared between the two groups at three intervals, preoperatively, 24 hours and 7-10 days postoperatively. Pain and swelling during the follow up period were also recorded in both groups and compared in the second part of the study. Results : In the first part of the study, comparison of body temperature, CBC components (except WBCs) showed no significant difference between the two groups during the follow up period. All parameters were within the normal range at all intervals, which indicated absence of infection. In the second part, 38% of patients in the antibiotic group, compared to 54% of the non-antibiotics group, had one or more complications during the follow up period. However, three patients from the antibiotic group compared to one from the nonantibiotics group reported having a swelling of some degree. Conclusion : Based on our objective parameters (body temperature and CBC components), both groups showed no signs of infection during the follow up period. However, the results related to pain and swelling were less conclusive, probably due to small number of patients included in the study. Accordingly, we are unable to provide definite recommendations on antibiotics use in third molar surgery.

Necrotizing fascitis is a severe soft tissue infection characterized by extensive necrosis of superficial fascia, suppurative fascitis, vascular thrombosis, widespread undermining of surrounding tissues. Associated systemic problems are widespread undermining of surrounding tissues, Associated systemic problems are common, with chronic alcoholism and diabetes being most prominent. Most commonly this disease presents in the extremities, trunk, and perineum. Necrotizing fascitis of dental origing is rare and its fulminating clinical course is not well documented in the dental literature. The present report is a case of necrotizing fascitis following vital extirpation of the pulp in a patient with uncontrolled diabetes mellitus and liver cirrhosis. Originally throught to be caused by hemolytic streptococcus organism or stphylococcus aureus, advances in anaerobic culturing have shown it to be a synergistic bacterial infection involving aerobic and ovligate anaerobes. it is relatively rare in relatively rare in haea and neck regions. If it was not diagnosed and treated in early stages, necrotizing fascitis can be potentially fetal, with a mortality rate approaching 40%. It's treatment requires early recognition, prompt and aggressive surgical debriment and proper supportive cares, such as, antibiotic therapy, fluid resuscitation and correction of metabolic and electrolyte disorder, resolving of the underlying systemic disease. Recently, we experienced two cases of necrotizing fascitis in cervicofacial region, One patient was 60 years old male with uncontrolled Diabetes Mellitus and other patient was 48 years old with steroid therapy during 30 years. Local surgical wound healing was successful but, patients were died after admission, because of lung abscess, gastrointestinal bleeding, septic shock and respiration hold.
