Currently dental laser is used at a variety of dental treatment and many favorable clinical case reports are presented. We performed this study for the presentation of the validity of dental laser which are available and supportable in the oral and maxillofacial surgery. From October, 1998 to March, 1999, dental laser was used in 70 cases. Male patients were 38, female 32. The age ranged from 5 to 77, with a mean of 45.4. Indicated cases were 18 chronic periodontitis, 11 infections, 6 atypical pain, malignant or benign tumor, precancerous lesion, abnormal frenum, TMJ disorder, mucocele, and so forth. $CO_2$ laser(Sharplan 15F, Sharplan Co.) was used in 40 cases, Ho-YAG laser(Duopulse 2000, Excel Co.) 11, Nd-YAG(Duopulse 2000, Excel Co.) 18. We present and discuss about the objectiveness, availability, and future application of laser with case reports.

Distraction osteogenesis is a well-estabilished procedure of membraneous bone formation and has been used to correct craniofacial deformities in dentofacial orthopedic-surgery area for decades. In this articale, distraction osteogenesis is used for treatment of facial asymmetry. The patient underwent procedures to lengthen the mandibular ramus and body. After distraction, orthodontic treatment was done for ooclusal settling.

Diagnosis of maxillofacial lesions is very difficult. Recent developments in computed tomography enable the production of three dimnesional images of complex anatomical structures from a series of conventional computed tomographic sections. Methods of three-dimensional analysis of computed tomographic images have recently been described. Mostly, reports have concentrated on applications relative to congenital deformities. In this report, one method of three dimensional reformatting is reviwes. Images formed by this method have solid surface appearance and can be color enhanced and manipulated to isolate anatomic structures of interest. The program allows tissue densitis, volumes, and distances. This report emphasizes maxillofacial applications other than those previously reported in the surgical and radiological literature.

Ketamine HC1(Phencyclidine derivative) is a white, crystalline substance with melting point 259℃. It is soluble in water to a 20% clear, colorless solution. a 10% aqueous solution has a pH 3.5. The chemical structure is 2-(O-chlorophenyl)-2-(methylamino) cyclohexanone hydrochloride. It is a rapid acting, nonhypnotic, nonbarbiturate drug with a wide safety margin. The author used the anesthetic ketamine hydrochloride for oral surgery procedure in 16 patients(2 to 33 years). Anesthesia was achieved with a single intramuscular injection by introduction of manufacture. Result obtained as follows : 1. It was easily administered. 2. Onset time was rapid and duration was short. 3. The mild cardiac stimulation resulted in moderate increase in the blood pressure and pulse. 4. There was no significant respiratory depression. 5. The airway can be maintained without artificial support or endotracheal intubation. 6. All protective reflex maintained, which was important in oral surgery. 7. The best results were achieved in pediatric patients than adults.

치과의술의 발전과 시회·경제적인 인식의 발달로 심미안이 높아져 치과학 영역에서도 미적개념이 자연적인 것으로 환원하는 추세에 맞춰 치수치료시에 환자가 치료후 변색에 대한 우려를 종종 표시한다. 이러한 변색된 무수치아에 대한 표백술은 오래전부터 사용되어 왔으나 구강내 생활치아 모두가 전신적인 질환 및 환경요인등에 의하여 변색될 경우의 표백술은 아주 최근에 소개된 데 불구하며 (Cohen, 1970), 아직 널리 사용되지 않는 실정이다. Cohen의 보고이후 Arens(1972, 5증례), Corcoran(1974, 6증례), Cohen(1979, 18증례)의 테트라싸이크린에 의해 변색된 생활치아의 성공적인 표백술에 대한 보고가 있었으며, McInn(1966), Bailey와 Christen(1968), 그리고 Wayman과 Cooley(1981)에 의한 불소중독증에 걸린 변색생활치아의 표백술이 보고되었다. 이에 간편한 생활치아의 표백술을 소개하고자 한다.

With the recent progress of microsurgical techniques, radial forearm free flap has an established place in oral reconstruction. Providing thin, soft and pliable skin with a large and constant vascular pedicle, this flap is optimal for intraoral reconstruction. One of the disadvantages of the flap is donor site morbidity, therefore various methods can be used to reduce it. A male complained of palatal and retromolar area mass with ulceration, which was diagnosed as squamous cell carcinoma. He also complained of discomfort and mouth opening limitation, attributed to the location and characteristics of the mass. Because of mouth opening limitation, mandibular swing approach was performed to allow for the surgical approach to the mass. After the surgical excison of the lesion, the intraoral defect was successfully reconstructed with radial forearm free flap.

There are many vessels in oral and maxillofacial region. Therefore blood oozing is a frequent findings in this area when operation takes place. Beacuse of this, most oral and maxillofacial surgeons as well as operators of this region usually use bosmine soaked gauze for oozing control during operation. Theoretically overdose of systemic epiniephrine(bosmine) may lead to pulmonary edema due to secondary systemic volume overload. For this reason, oral and maxillofacial surgeons should give more attention to the use of bosmine soaked gauze. In spite of this possibility, epinephrine induced pulmonary edema using bosmine soaked gauze has not been reported. We experienced one case of pulmonary edema which was induced by epinephrine overdose by bosmine soaked gauze that has not been diluted by mistake in preparing bosmine soaked gauze. The authuors report a case with review of literature.

Mucormycosis is an acute opportunistic infection caused by a saprophytic fungus found in soil, decaying fruits and vegetables. Numerous predisposing risk factors are associated with mucormycosis, although most cases have been reported in poorly controlled diabetics or in patients with hematologic malignant conditions. Throughout the history of mucormycosis, from the first case in humans reported in 1885 by Paltauf, through publication by Gregory et al of the first observation of rhino-orbital cerebral mucormycosis in 1943, to the report by Harris in 1955 of the first known survivor, little has changed in the diagnosis and outcome of this disease. Without treatment, the patient may die after an interval ranging from a few days to a few weeks. Regulation of diabetes mellitus and a decrease in the dose of immunosuppressive drugs facilitate the treatment of Mucormycosis. Extensive debridement of craniofacial lesions appears to be very important. intravenous amphotericin B is clearly of value. This is a case report of a patient with mucormycosis in maxilla. He was an uncontrolled DM patient, and for the treatment of intravenous amphotericin B and sequestrectomy were applied.

Dental assistant in South Korea, The work is overlapped considerably between dental hygienist and dental practical nurse. Moreover, dental technician, hospital coordinator work in dentistry consultation deeply. It cause friction among work scope of occupation's type. Accordingly It is purpose to get basic data which is necessary to deduce division of work training and utilization of human resources in oral health distinguish clearly between business occupations. Also compared and analyzed via analysis of frequency and ANOVA above 10 works around something legal work of dental hygienist regarding work reality of dental assistant in dental clinic and hospital. Compare with scaling, representative item about 10 works center on legal work of dental hygienist, is implementing dental technician 9(75%), practical nurse 64(87.67%), etc. 11(64.71%). Dental assistant except dental hygienist is implementing indigenous legal work of dental hygienist. Dental institution secure enough man power, It is suggested necessity for policy means regarding role and work scope of dental assistant.

Return of facial nerve function is important in patients with facial nerve paralysis by trauma. Sometimes, delay in diagnosis of facial nerve paralysis make recovery of facial nerve function difficult. Traumatic facial palsy mostly occur after temporal bone fracture in unilateral. Temporal bone fracture after head trauma are divided into the three group; longitudinal fracture, transverse fracture and mixed fracture. The most common symptoms are hearing impairment, bloody otorrhea, loss of consciousness and facial nerve paralysis. The early care of temporal bone fracture involves facial nerve paralysis. And there has been many discussion and study in the treatment of the immediate or delayed facial palsy ; examply, surgical approach, time and methods. We have managed a patient with unilateral facial nerve paralysis after longitudinal temporal bone fracture in mastoid process and conservative facial nerve decompression was performed. We have obtained good result and report this case with review of literatures.
