The most common and the most serious complication of the burn is infection, which is to a certain extent inevitable in the light of present knowledge and experience. From the burn wound as a rule there may be cultured at any given time the prevailing flora of the individual patient and of the hospital attendants and ward environ ment. Even without contamination from outside sources, organisms embedded in hair follicles and sweat glands survive the sterilizing effects of heat and serve as potential sources of localized and systemic infection. With necrotic tissue serving as nutrient material for pathogens there may occur, in succession, cellulitis, extending necrosis, lymphangitis and final septicemia. This is to report a case of osteomyelitis due to facial burn of 32 year old Korean male. The authors treated the patient by curettage and thin split thickness skin graft. The post operative course was uncomplicated and result was excellent.

Disturbances of the interrelationship among the host, environment, microorganism will cause the infection clinically. Infection can be classified into bacterial, viral, fungal origin, Bacterial infection is most common due to dental caries, periodontal disease. These infections have the potential to spread via the fascial spaces in the head and neck region. We have undertaken clinical studies on infections in the oral and maxillofacial regions by analyzing 78 hospitalized patients in the Dept. of Oral and Maxillofacial Surgery, Dong-A University Hospital from 1994 to 1997. The results were as fellows; l. Odontogenic infections were most common with the incidence of 84.6%. 2. Considering the number of involved space, single space was 83.3%, double or more space was 16.6%. The most common fascial space involved was submandibular space and followed by buccal space, 3. The most causative organism isolated from the pus cultures was streptococci group 35.4%. 4. Antibiotics were administrated in all cases, and surgical incision and drainage was performed in 87.2%. 5. Combined administration of penicillin and aminoglycoside was most common in 34.6%.. 6. 7 cases were diagnosed as Ludwig's angina and tracheostomy was done in 2 cases of them.

We have conducted a retrospective study of 224 patients with the diagnosis of oral and maxillofacial infection who had been treated between 1988 and 1999 at Gyeong-Sang National University Hospital. This study was aimed to furnish the data of oral and maxillofacial infection and to aid diagnosis and treatment. The most common fascial space involved, as determined by clinical, radiologic, and operative findings, were the submandibular space(39.4%). The most frequent cause of oral and maxillofacial infection was odontogenic 68.8%. In the odontogenic cause, dental caries was the most common cause. Two-hundred three patients required surgical drainage of the abscess. Seventeen patients needed tracheostomy for airway control. The overall mortality was 0.9% despite aggressive anti-microbial therapy and early surgical intervention. All other patients had an uneventful recovery without major complication except osteomyelitis case(6.0%). The combination of early radiologic diagnosis, effective antimicrobial therapy, and intensive surgical management contributed to the good prognosis.

Ankylosis of joint is defined as limited movement due to infection, trauma, or surgical procedure. A 59-year-old female with a chief complaint of limited movements during mouth opening had a positive history of trauma to her right TMJ area about 5 years ago. From that time, progressive mouth opening limitation and intermittent pain have occurred. At the time of admission the patient showed mandibular deviation to the right side during mouth opening, with a maximum opening limited to 5 mm. On plain radiographs, right condylar enlargement and joint space reduction by newly formed bony tissues were observed. CT scans showed right condylar enlargement, cortical sclerosis, and thickening of the condyle, articular fossa and articular eminence.

Usage of the rubber dam has been advocated by countless number of dentists. The advantages of the rubber dam such as the following are well-known 1. Moisture control. 2. Improved field of vision. 3. Ease of approach. 4. Soft tissue retraction and Injury prevention. 5. Prevention of aspiration of materials or instruments. 6. Shortened chair time. 7. Induction of nasal breathing during administration of $N_2O-O_2$ sedation. Recent reports indicate the rubber dam can protect the dental staffs from the infection when treating HBV or HIV positive patients. Also, improved moisture control and freeing of both hands allowed by the rubber dam makes it very useful when bonding orthodontic brackets. This case study presents the various clinical application of the rubber dam on patients visiting SNUDH dept. of pediatric dentistry to emphasize the importance of its use in pediatric dentistry.

Following anti-retroviral therapy (ART) or highly active antiretroviral therapy, there is an increased response to latent infections such as herpes zoster, which may lead to their reactivation. This is a result of improved immunity brought about by ART, also termed immune recovery syndrome. A 75-yearold male patient arrived at our institute with widespread vesicles and scabs on the right half of his face and oral cavity, suggesting the involvement of the trigeminal nerve. The patient had a history of being on ART two months earlier and a history of tooth extraction eight days prior to his arrival at our institute. The incidence of human immunodeficiency virus (HIV)-positive cases amongst herpes zoster cases is high, and these patients become susceptible to infections following ART. Therefore, regardless of the presence of risk factors, every herpes zoster patient should be tested for HIV infection, and high anti-retroviral therapy should be commenced/reinstituted as soon as possible. In addition, the treating physician should maintain a high level of vigilance for the patient during the first few months of ART, the peak incidence of immune recovery inflammatory disease.

Lichenoid dysplasia is a lichenoid features with epithelial dysplasia clinically and histopathologically similar to oral lichen planus. It can be clinically mistaken for oral lichen planus, but has histopathologic features of dysplasia and a true malignant predisposition. The clinician should be able to differentiate between oral lichen planus and lichenoid dysplasia for the proper management. We experienced a 75-year-old man with erosive, erythematous lesion on the left buccal mucosa previously diagnosed as oral lichen planus. He underwent surgical excision and the final histopathological result confirmed it to be lichenoid dysplasia with massive candidal infection. We report this case with a review of the related literature.

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.
