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.

Objectives: The objective of this study was to examine the effect of mentoring function on job satisfaction, organization commitment, and turnover intention in the newly employed dental hygienists. Methods: Two hundred and fourteen dental hygienists in Daegu and Gyeongbuk completed a self-reported questionnaire from January to May 2013. The instrument for the questionnaire consisted of mentoring function, mentoring personality, job satisfaction, organizational commitment, and turnover intention. The data were analyzed by frequency analysis, ANOVA, correlation analysis, and multiple regression analysis. Results: The longer duration of the mentoring for the newly employees strengthened job satisfaction and organization commitment. The mentoring function had a positive effect on job satisfaction and organization commitment, and decreased turnover intention. The higher quality of personality overcome the turnover intention. Conclusions: The mentoring is very important to enhance the job satisfaction and organization commitment in the newly employees. Loner duration of work(${\beta}=.268$, p=0.008) explained higher job satisfaction. Higher quality of personality(${\beta}=0.279$, p<0.001) also had higher job satisfaction. The explanation power of the model was 36.5% and the revised model explanation was 35.6%. The effective mentoring is closely related to job satisfaction and organization commitment and it can reduce turnover intention.
