The carcinoma of the maxillary sinus occupies about 0.25% of all human cancers. The radiations therapy for maxillary sinus hs not been practiced widely in this country. The authors treated a case of relatively advanced maxillary sinus cancer with combined radium and external irradiation with a succesful result. The clinical course and treatment are introduced and evaluated in detail. The authors believe that the carcinoma of the maxillary sinus is a curable disease even though it is relatively advanced one.

Bisphosphonate inhibits the function of osteoclast, so they are widely used for multiple myeloma, Paget's disease, metastatic malignant bone disease, and severe osteoporosis. This drug is very effective for preventing severe complication of osteoporosis, some unpredictable complication occurred such as esophageal malignancy, atypical fracture of femur, and osteonecrosis of the jaw. Bisphosphonate related osteonecrosis of the jaw (BRONJ) is closely related with invasive, open bone surgery like tooth extraction. BRONJ associated with dental implant is rare, however, as the use of bisphosphonate increase, BRONJ cases with dental implant are increasing. In this article, we will describe the considerations during dental implant treatment for patient under bisphosphonate therapy.

Impaction of tooth is a situation in which an unerupted tooth is wedged against another tooth or teeth or otherwise located so that it cannot erupt normally. The supernumerary tooth is also called as hyperdontia and defined as the condition of having additional tooth to the regular number of teeth. The most common supernumerary tooth is a mesiodens, which is a mal-formed, peg-like tooth that occurs between the maxillary incisors. The supernumerary tooth is commonly impacted but they are frequently impacted on maxilla. Ectopic impaction of supernumerary tooth on mandibular condyle, coronoid process, ascending ramus, and pterygomandibular space is very rare condition. In this case, we report a case of impacted supernumerary tooth on mandibular sigmoid notch without definite pathologic change.

PURPOSE. This study was conducted to evaluate clinical validity of a zirconia full-coverage crown by comparing zirconia's wear capacity over antagonistic teeth with that of feldspathic dental porcelain. MATERIALS AND METHODS. The subject groups were divided into three groups: the polished feldspathic dental porcelain group (Group 1), the polished zirconia group (Group 2), and the polished zirconia with glazing group (Group 3). Twenty specimens were prepared from each group. Each procedure such as plasticity, condensation, and glazing was conducted according to the manufacturer's manual. A wear test was conducted with 240,000 chewing cycles using a dual-axis chewing simulator. The degree of wear of the antagonistic teeth was calculated by measuring the volume loss using a three-dimensional profiling system and ANSUR 3D software. The statistical significance of the measured degree of wear was tested with a significant level of 5% using one-way ANOVA and the Tukey test. RESULTS. The degrees of wear of the antagonistic teeth were $0.119{\pm}0.059\;mm^3$ in Group 1, $0.078{\pm}0.063\;mm^3$ in Group 3, and $0.031{\pm}0.033\;mm^3$ in Group 2. Statistical significance was found between Group 1 and Groups 2 and between Group 2 and 3, whereas no statistical significance was found between Group 1 and Group 3. CONCLUSION. Despite the limitations of this study on the evaluation of antagonistic teeth wear, the degree of antagonistic tooth wear was less in zirconia than feldspathic dental porcelain, representing that the zirconia may be more beneficial in terms of antagonistic tooth wear.

An intracapsular and pericapsular infection of the temporomandibular joint (TMJ) is rare. The invasion of bacteria into the joint space can occur through several routes. Among them, hematogenous spread is most common. This report describes three cases of abscess formation in the TMJ (intracapsular and pericapsular infection). The patients were treated with supportive care and surgical intervention (incision and drainage) under hospitalization, and their symptoms had improved. Pain of the TMJ is a typical symptom of temporomandibular joint disorders (TMD). On the other hand, an infection of the TMJ can also cause pain on the affected side, and can be misdiagnosed as routine TMD. Therefore, the possibility of an infection of the TMJ cavity should be considered when treating TMD.

Dentists who want to perform sedation must have abilities to control any emergent situation that may occur during treatment procedures. In the 2010 guideline for the use of sedation by dentists, he/she must has valid certifications for basic life support (BLS) and for advanced cardiovascular life support (ACLS). The Korean Association of Cardiopulmonary Resuscitation (KACPR) has made a contract with the American Heart Association for education and certification. From 2004, they have held many courses for BLS and ACLS providers and instructors. The author of this research participated in the above mentioned courses and qualified as a BLS provider, BLS instructor and ACLS provider. The present paper was intended as an introduction to and arrangement of BLS and ACLS courses for health care providers through a year of experience. However, the previous course of the ACLS provider was focused more toward medical doctors. It is necessary to develop a new advanced course for dentists who employ sedation in their medical practices.

Korean dentist's new mission was extended in dental practice field since the National Liberation Day of Korea. Modern dentistry development were due to the introduction of american dentistry, the development of Military dentistry, the unified academic activities koreans dental Association and improvement of korean dentist system. Modern dentistry development factors were as follows, First, Seoul National University's professors have been sent for studying abroad since May 1954. Thanks to this advanced system, each dental department established branch academy. Researchers and academic activities were increased in Seoul National University, Second, from January 1954, the military started training program to the korean dentists in the United States, and also the korean dentists were sent to the US Army hospital in korea for practical training courses (On the Job Training) so they could get chances to learn the advanced dentistry. During the korean war, the oral surgery dentists enlarged treatments to the maxillofacial field. Third, korean Dental academy meeting, special lectures and tables clinic from 1947 were contributing to the development of modern dentistry in the transmission of knowledge and skills. Since 1955 "Dentistry(齒學)" with a focus on the translation of foreign literature also developed modern dentistry. Since 1958 the International dental conference could broaden dental knowledge, it also provided opportunities to communicate with the world dentistry. On Oct 11, 1962, revised the Articles of association in Korean Dental academy and korean dental association unified meeting and enhanced the conferences. Improvement of korean dentist system in 1964 unified the dentists as new dentist education. Articles, case reports, review articles and academic meetings of korean dental association from 1946 to 1969 analyzed to demonstrate the development of korean modern dentistry, The titles and lectures were classified according to department and they were organized by topic.

Korea became an aged society as of 2018, and will have plunged into a super-aged society by 2025. For the dental treatment of elderly patients, their general conditions are to be considered to make appropriate treatment plans and strategies, based on advanced knowledge of geriatric dentistry and clinical experience. In this study, the social demand for geriatric dental specialists for the treatment of the elderly of Korea is investigated by looking at their general health conditions, ADL (Activities of Daily Living), and IADL (Instrumental Activities of Daily Living), along with the review of the advanced training programs of geriatric dentistry in other countries.
