Various mucosal lesions are originated in oral cavity and trauma is most common cause of these lesions. Definitive treatment of these lesions is stop of traumatic events and removal. There are two representative removal methods in medical fields; conventional mess or LASER. Compare to conventional mess technique, LASER has several advantages such as bleeding control, pain reduction. Of the various LASER systems, $CO_2$ LASER is regarded as best choice for general practitioners due to its convenience, universal use and high cost/benefit effects. In these article, we report the treatment cases of mucocele, fibroma, and leukoplakias using $CO_2$ LASER. Eventhough there are malignancy potential of oral mucosal lesion especially leukoplakias, careful history taking, clinical examination, and regular check-up will help the general practitioners to manage these lesions. Simple and relatively safe oral mucosal lesions have to be treated more in general dental practitioners.

변진석,서봉직,Byun, Jin-Seok,Suh, Bong-Jik 대한안면통증구강내과학회 2007 Journal of Oral Medicine and Pain Vol.32 No.4

Occlusal stabilization appliance is one of the most common treatment option for management of temporomandibular disorders. It acts in oral cavity for several hours per day, and usually it will take at least 6 months to 2 years of total wearing periods to take a treatment goal. In the oral cavity, occlusal stabilization appliance, unintentional manner, is able to acts as a reservoir of bacteria and protect bacteria from saliva and oxygen. This condition is so favorable to many bacteria such as S. mutans and other anaerobes, usually have been reported as causative factors of dental caries, periodontal disease and oral malodor. In this study, we investigated anaerobic bacteria and S. mutans count before and after occlusal stabilization appliance use to evaluate the possible role of occlusal stabilization appliance as protector of these bacteria. Four men(average 27.5 years) wore maxillary occlusal stabilization appliance at each night(average 9 hours) for 5 days. we swabbed saliva-plaque mixed sample at 3 different site(maxillary left 2nd molar, maxillary left central incisor, mandibular left 2nd molar) before and after occlusal stabilization appliance use. Each samples were plated in (1) anaerobic blood agar medium, (2) selective S. mutans medium(MS-MUTV) and incubated in anaerobic chamber($CO^2$ 10%, $37^{\circ}C$) for 72 hours. Each bacterial colony forming unit(CFU) were counted with naked eyes. From obtained data, we can conclude as follows: 1. There was some changes about anaerobic bacteria and S. mutans count in oral cavity after occlusal stabilization appliance use. 2. The number of anaerobic bacteria was significantly increased at maxillary 2nd molar(P=0.003), maxillary central incisor(P=0.020) after occlusal stabilization appliance use compared with before. 3. Occlusal stabilization appliance use itself had indirect effect to increase the number of anaerobic bacteria at other uncovered opponent tooth site. 4. The number of S. mutans was significantly increased at maxillary 2nd molar(P=0.043), maxillary central incisor (P=0.049) after occlusal stabilization appliance use compared with before. 5. Occlusal stabilization appliance use itself had not any effect on the number of S. mutans at other uncovered opponent tooth site.

The purpose of this paper is to investigate the structure of cost-sharing for oriental medical services in the national health insurance. Out-of-pocket payment in ambulatory oriental medical care is a co-payment of KRW3,000 up to total expenses of KRW15,000, and co-insurance rate of 30% thereafetr. The empirical analysis based on medial claims data shows that the frequency of medical claims for outpatient care are mostly concentrated just below a total expenses of KRW15,000, and it decreases beyond a total expense of KRW15,000, while it rebounds between KRW17,000${\sim}$20,000. This means the current co-payment(KRW3,000) in oriental medical services should be applied up to a total payment of KRW17,000${\sim}$20,000, or the level of co-payment should be adjusted upward to KRW45,000 in order to be consistent in cost-sharing, between co-payment and co-insurance.

If patients complain about sudden ill-fitting occlusal sensation(acute malocclusion), a dentist has to consider many possible causes about that. Acute malocclusion is characterized its sudden onset and mainly can be caused by teeth and its related structure problem. But we always keep on mind that acute malocclusion also can be caused by temporomandibular disorders In this 3 cases of acute malocclusion, evaluating by patient history, clinical and radiographic findings, we diagnosed them as 1. Lateral pterygoid muscle spasm, 2.. Retrodiscitis, 3. Osteoarthritis. Through this non-odontogenic acute malocclusion cases, we emphasize the key of diagnosis is on comprehensive and careful patient history taking and clinical examination.

Mess removal, electrocoagulation, cryosurgery are conventional methods in the treatment of various oral mucosal diseases. However, there are several problems or complication during or after surgery using conventional tools. Recently, LASER gradually become useful tool in the surgery of oral mucosal diseases. Of the LASER, carbon dioxide-mediated LASER is widely used one. Carbon dioxide LASER has many advantages such as good bleeding control, decreased damage to adjacent tissue, decreased pain and swelling, reduced scar formation, even bacteriocidal effects. In this reports, the author describe pros and cons of LASER, especially focused on carbon dioxide, and shed light on the field of LASER application in treatment of various oral mucosal diseases.

법치의학적 연령 감정은 개인 식별에 있어 중요한 역할을 한다. 본 연구는 한국 연령 감정 대상자들의 사회적 특성을 분석하는 것을 목적으로 한다. 2012년 3월부터 2013년 3월까지 경북대학교 치과병원 구강내과에 연령 감정을 의뢰한 대상자들에게 설문조사를 실시하였다.결과는 다음과 같다: 1. 성별 분포에서, 남성(42.86%)보다 여성(57.14%)이 더 많았다. 50대와 60대 이상의 고령자가 대다수였으며(89.28%), 40대 아래로는 한 명의 의뢰인도 없었다. 의뢰인들의 대부분이 초등학교 졸업 이하의 학력을 가지고 있었다(69.64%). 2. 호적 상 연령과 의뢰인이 주장하는 연령 간의 차이가 나게 된 가장 큰 이유로는 가족 및 친척의 실수로 인한 것이 가장 많았다(80.36%). 연령 감정을 통해 얻고자 하는 목적은 사회 복지 혜택(62.50%), 사회적 인관 관계 문제(12.50%), 단지 바른 나이를 찾기 위해서(10.71%), 직업과 관련한 문제(8.93%) 순이었다. 3. 연령 감정을 하기 위해 치과(구강내과)를 찾게 된 경로로는 관공서의 비중이 높았으며(48.21%), 친구나 지인(21.43%), 대중매체(14.29%), 병의원(10.71%) 등을 통한 경로가 뒤를 이었다. 법치의학적 연령 감정에 대한 의뢰인들의 이해도는 10점 만점에 7.03점으로 높은 수준이었다. 절반 이상의 의뢰인들에게서 현재의 연령 감정 비용에 대해 만족하는 것으로 나타났다. 4. 법치의학적 연령 감정을 통해 감정된 연령과 의뢰인들이 주장하는 연령 간에는 57.14%의 근접도를 보였다. 1년 간 조사한 연령 감정 대상자들의 23.53%가 법적으로 연령 정정을 하게 되었다. Age estimations by forensic odontology play a great role in personal identification. The purpose of this study was to analyze the characteristics of age estimation cases in Korea. Surveying clients who requested age estimation at the Department of Oral Medicine, Kyungpook National University Dental Hospital from March 2012 to March 2013. The results were as follows: 1. On gender distribution, females(57.14%) were more than males(42.86%). The elderly with 50's and over 60's were majorities(89.28%) of clients, and no clients were below 40's. Most of clients were equal to and lower than elementary school graduate(69.64%). 2. The most frequent reason for age discrepancy between registered age and alleged age was mistakes by family or relatives(80.36%). The purposes of age estimation were welfare(62.50%), social relationship problem(12.50%), to find right age(10.71%), and occupation(8.93%). 3. In order of route to visit at Department of Oral Medicine, they were via government office(48.21%), acquaintances(21.43%), mass media(14.29%), and clinic(10.71%). Clients had high degree of comprehension on age estimation with forensic odontology (scored 7.03 out of 10). The 2/3 of clients were satisfied with present fee for age estimation. 4. The percentage on the proximity of estimated age to alleged age was 69.81%. 4(11.43%) clients were approved on age correction by court.

This paper estimated the demand and supply of physicians for oriental medicine for the period of $2009{\sim}2019$. Two equation models were used in the estimation of manpower. In 2004, the total number of physicians of oriental medicine was amounted to 13,662 registered and 10,532 available in clinical practice, respectively. According to estimates in the study, overall excess supply of physician manpower in oriental medicine was expected in the period, such as $5,300{\sim}5,700$ persons in 2009 and $900{\sim}1,700$ persons in 2019. However, the excess supply would be mitigated after 2019 mainly due to an increase in demand for oriental medical services. Specially, opening medical service market to overseas could be an exogenous variable in physician supply. An alternative manpower policy for oriental medical doctors is needed in a way of controlling oversupply.
