Intentional replantation of the posterior teeth has been performed as a last resort except extraction when it is impossible to perform the conventional endodontic or surgical endodontic treatment. Many studies have done with the prognosis, and root resorption, of which the responsibility might have been injury of periodontal ligament and remaining periodontal lesion, proved to be major cause of failure. Intentional replantation, however, can exclude anatomic difficulty, risk of nerve injury, and maxillary sinus trauma that surgical access can raise, especially in posterior teeth, and it is reported that success rate is not less than surgical endodontics, independent of replantation of traumatically avulsed teeth. The success of intentional replantation can be evaluated with, clinically, reduction of pocket depth, pain and mobility(physical mobility), and, radiographically, hard tissue formation, reduction of periapical radiolucency. In this case report, for the maxillary left first bicuspid with dens evaginatus that had periapical lesion, painfulness, mobility and showed no reduction of mobility after even extirpation and a number of irrigation, extraction followed by extraoral root filling with calcium hydroxide and replantation was performed. Based on many studies, it is concluded that hard tissue formation capacity of calcium hydroxide, preceded extirpation before extraction, and careful extraction without injuring periodontal ligament affected successful results of this case.
Objectives: This study analyzed the perception towards clinical practice education content held by dental hygiene students in dental institutions and their perceived importance of dental hygienists' clinical duties. Methods: The subjects of this study were 182 dental hygienists who were working at dental institutions in Seoul, Gyeonggi, and Chungcheong areas. A survey was conducted with a self-administered questionnaire. In the questionnaire, the clinical practice contents were classified into observation, preparation, and performance, and the importance of clinical duty was measured with a 3-point scale. For the clinical practice contents and the importance of duty, descriptive statistics and chi-square test were performed, and the study results were analyzed using STATA 11.0. Results: With regard to clinical practice contents, observation was mainly performed in oral & maxillofacilal radiology, preventive dentistry, periodontal medicine and oral medicine. In primary care and infection control, practice and observation were mainly performed. In the department of orthodontics and pediatric dentistry, observation and preparation were mainly conducted, while in oral surgery, conservative dentistry observation, preparation and practice were all conducted. With regard to clinical practice contents according to the dental institution, there were statistically significant differences in the type of dental institution and the duty (p>0.05). In terms of the importance of dental hygienist's duty, infection control, toothbrushing education for each patient, removal of plaque, and patient education after surgery were considered important. Conclusions: For clinical practice of the dental hygiene department, the education contents should be standardized in accordance with the importance of the dental hygienist's duty, a protocol for operation of practice should be developed, and a method of standardization of evaluation should be sought in the future.
Objectives: The purpose of the study was to investigate the awareness towards employment in the dental hygiene students. Methods: A self-reported questionnaire was completed by 425 dental hygiene students in Chungcheongdo and Gyeongsangdo from July to September, 2014. Except incomplete answer, 401 data were analyzed using SPSS 20.0 program. The questionnaire consisted of three questions of general characteristics of the subjects, nine questions of awareness towards employment, six questions of awareness of employment preparation, and eleven questions of awareness of employment outlook. Results: The dental hygiene students prefer to dental hygiene related institution including dental hospital, dental clinic, general hospital, and university hospital. The awareness for the knowledge of desired employment institution was average. The main access for the information of the employment was internet, and senior and professor's advice, The most important preparations for the employment were a practical skill, trust, certificate, license, communication skill and English proficiency. The future outlook for the dental hygienist within five years was not optimistic, and the best way to overcome the weka point was specialization of the dental hygienist. Conclusions: This study will provide the useful information on improvement of employment strategy program for dental hygiene students.

Ectopic eruption is defined as abnormal eruption and results in malpositioned teeth and abnormal root resorption of adjacent teeth. Ectopic eruption, first reported by Chapman, occurs in 3% of the population and that mostly in the maxilla. Etiologic factors include narrow maxilla, large maxillary teeth, retarded calcification of the first molar, inclined eruption path of the first molar and retruded position of the maxilla. Impaction of the second molar is rare and occurs mostly in the mandible. Major causes are large teeth and insufficient arch length. Halterman has devised a method of distalizing a ectopically erupting first molar by cementing a band on the second deciduous molar with a hook soldered and a button bonded to the occlusal surface of the first permanent molar. Ectopically erupted posterior teeth should be treated early to maintain normal development of the dentition, harmony of facial growth and occlusal support, a failure to do so could result in severe malocclusion, periodontal damage and continued root resorption of the adjacent teeth. Early detection and treatment is thus vital. The author is submitting this report as he has obtained favorable results in treating a patient who came to the SNUDH Dept. of Pediatric Dentistry complaining of the first molar by using a modified Halterman appliance.
The purpose of this study was to offer the importance on factors of selecting dental institution according to general characteristics targeting general dental patients, and the information of having important influence upon choosing dental clinic and dental hospital. The survey was carried out from August 2009 to September. As a result of analyzing SAS(ver 9.1), the following conclusions were obtained. In the importance on factors of selecting dental institution according to general characteristics, it was thought to be important in convenience of movement or mobility such as distance, transportation, and parking convenience according to age level. According to final academic background, the importance in a factor of rumor in dental clinic was high(p < 0.05). According to job, the significant difference was shown in rumor of dentistry and parking convenience(p < 0.05). According to income, the factor in the appearance of training a medical specialist was indicated to be statistically higher in the group with over 5 million won than the group with under 2 million won(p < 0.05). Given seeing the distribution of opinion about dental hospitals (comparison with dental clinics), the excellence in the medical staff's ability was indicated to be the highest in all of the factor of influencing the use satisfaction(${\beta}=0.18$), the factor of influencing the recommendation level(${\beta}=0.21$), and the factor of influencing the re-use intention(OR=2.09).
The purpose of this study was to investigate the actual profile of dental clinic services used by foreigners who reside in certain regions of Korea. As a result, this study could come to the following conclusion: It was found that most of respondents had never received any dental treatment in Korea, but the largest number of respondents who ever experienced any dental treatment had visited dental clinics in their neighborhood for treatment. Most respondents allowed for public recognition of medical institution among others in terms of criteria about selection of dental care institution. In addition, our respondents not receiving any dental treatment during their residence in Korea primarily because they had 'no sufficient time' to use dental clinics, and secondarily because they had 'a burden of expenses spent in dental care'. Moreover, many respondents were unsatisfied with their use of Korean dental clinics. Based on these findings, it is necessary to further expand dental care services in practical aspect and establish relevant public health policies.
Purpose: There is a growing concern for the cost management of medical institutions. The purpose of this study was to estimate Activity-Based Costing (ABC) for dental implant cost. ABC refers to allocating resources or cost based on the activities of services. Materials and methods: A dental institution located in the metropolitan area was selected in this study. The tax accounting data of the institution were utilized to confirm total cost, and the institution was asked to make out clinical activities to figure out what activities were carried out. The direct cost and indirect cost for dental implant were separately estimated, and cost driver was analyzed to estimate the indirect cost accurately. Results: The rates of the direct and indirect cost respectively stood at 35.8 and 49.5 percent. The cost for a dental implant was found to be approximately 1,579 won, and the cost of prosthetic surgery and treatment that included implant surgery accounted for the largest portion of the cost, which was 470 thousand won (30%). And the weight of training and education on dentistry was relatively higher than that of the other kinds of treatment. Conclusion: In order to ensure accurate and scientific costing for dental implant, not only direct medical procedure but every pre- and post-procedure activity should fully be taken into account. Pre-activities, post-activities, education and training are included in the indirect cost, but all these activities are mandatory and associated with the quality of treatment and the satisfaction level of patients.
Objectives : This study was conducted during the period from August 30 to September 9, 2011 in order to survey difference in the general perception of medical market opening and factors related to the choice of foreign hospitals among dental hygiene and nursing students at universities in Seoul. Methods : For this purpose, 438 students were surveyed using a questionnaire and collected data were analyzed using SPSSWIN 18.0. Conclusions drawn from this study are as follows. Results : 1. With regard to dental hygiene and nursing students' perception of medical market opening according to general characteristics, significant difference was not observed according to gender, experience in working at a hospital, medical institution used, and the frequency of using medical institutions, but significant difference was observed according to department, and interest in healthcare-related news. 2. There was significant difference in dental hygiene and nursing students'pro/con attitude toward medical market opening, but not in gender, experience in working at a hospital, medical institution used, and the frequency of using medical institutions. 3. With regard to intention to visit and revisit foreign hospitals, there was significant difference between dental hygiene and nursing students in intention to visit but not in intention to revisit. Conclusions : The results of this study suggest that more research on the medical market opening portion dental hygiene and nursing students' perception and attitude did not differ significantly, so the more accurate and open markets for a variety of medical education and school education and a variety of materials through hands-on experience be grasped should allow. Furthermore, students' acquisition of accurate prior knowledge about medical market opening is expected to be helpful to activate their employment in overseas.

The air abrasive technique is a non-mechanical method by which teeth are treated before restoration and stains and calculi are removed from tooth surfaces using the kinetic energy of small particles. The air abrasive technique in dentistry was first introduced in the 1950's with as instrument called 'Airdent'. But, as the main restorative materials of the period were amalgam and gold, and the instrument's inability to control the flow of particles caused the particles to be spread throughout the clinics, widespread use was not possible. In the 1990's, as these techincal problems were solved and more interest in new restorative materials rose in an effort to preserve sound tooth structure, new developements took place in instruments related to the air abrasive technique. The air abrasive technique produces less pressure, vibration and heat that might cause patient discomfort and facilitates the preservation of sound tooth structure. It also reduces the need for anesthesia and is less harmful to the pulp. Other advantages include increase in dentin bonding strength of composite resin, lower possibility of saliva contamination and maintenance of a dry field. But there is not direct contact between the nozzle and the tooth, the operator cannot use his or her tactile sense and must rely solely upon visual input. Other disadvantages are: the tooth preparation depends on the operator's ability; alpha-alumina particles, after bouncing off the tooth surface, cause damage to dental mirrors; the equipment is expensive and takes up a certain amount of space in the clinic. The author conducted case report using the air abrasive technique on patient visiting the Department of Pediatric Dentistry at Seoul National University Dental Hospital and arrived at the following conclusions. 1. The tooth preparation capability of different air abrasive devices varied widely among manufacturers. 2. It was more effective in treating early caries lesions and stains compared to lesions where caries had already progressed to produce soft dentin. 3. The cold stream and noise caused by the evacuation system was a major cause of discomfort to pediatric patients. 4. As there is no direct contact with tooth surface when using the air abrasive technique for tooth preparation, considerable experience and skill is required for proper tooth preparation.
