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.

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 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.
