Tooth impaction may lead to malocclusion, root resolution, cyst or aberrant changes in adjacent teeth. Clinical and radiographic examinations are used to locate the impaction, and appropriate treatment plans must be made to relocate the impacted tooth. When surgically exposing the impacted tooth, periodontal considerations to conserve maximum amount of soft and hard tissue are used. Oral hygiene instructions are emphasized to maintain sound periodontal health. Securing enough space for the impacted tooth and proper anchorage is important. Proper use of force and mechanics is crucial to prevent such complications as root resolution. Various patterns of orthodontic traction may be employed as situation permits. Most impaction cases can be managed with orthodontic traction to restore function and esthetics, provided that early detection and proper diagnosis and treatment planning are made.

With change in the pattern of disease occurrence and increase in the interest in health, efforts to assess the health status on patients covering their subjective awareness at the same time as clinical and objective evaluation on health are continued. To measure health-related quality of life can be one of these efforts. This study was performed to evaluate the relevance of the quality of overall health-related-life and oral health condition. Also the second year (2014) materials in the 6th the National Health and Nutrition Survey were applied to this study. The factors affecting general health related quality of life measured by EuroQol-5 dimension (EQ-5D) have been confirmed by gender, age, education level, income level, private health insurance, perceived health status, toothache experience during the last 1 year, remaining tooth number. As oral health plays an important role in determining the overall health conditions, objective oral health state influences the whole body health. Hence, it can be regarded that oral health is ultimately related to the general health-related quality of life.

Immunostaing intensity of Dynamin II protein in ameloblast during mouse tooth development showed a significant increase of 48% at the postnatal day 3 and a significant increase of 50% at the postnatal day 5 as compared with the postnatal day 1, but showed a significant decrease of 16% at the postnatal day 7 and a significant decrease of 12% at the postnatal day 10 as compared with the postnatal day 1. From the above results, Dynamin II had relevance to secretion of amelogenin, ameloblastin, enamelin and matrix metalloproteinase-20 proteins for enamel formation in ameloblast. Dynamin II may be involved in the transport of vesicles containing proteins for enamel formation through the acceleration of vesicular formation and may be had a good possibility of secretory regulation of proteins for enamel formation in ameloblast. Therefore, Dynamin II have potential for being used in the field of gene theraphy for periodontal disease and in the regeneration for enamel and dentin tissues lost to dental caries.

The purpose of this study is to determine the demage of tooth surface changes according to exposure time of commercially available green grape juice and pomegranate juice. Extracted healthy human premolar enamel surfaces were used. Control group immersed in phosphate-buffered saline (PBS) and 10 ml of commercially available green grape juice and pomegranate juice applied experimental group was divided into 7 groups. The pH of the experimental juice was measured, and the change and micrographics of the surface were confirmed through a Scanning Electron Microscope (SEM). It was found that the more the immersion time between the tooth surface and acid juice, such as damage to the tooth surface, has a greater effect on the surface damage. Based on the results of this study, it is necessary to reduce the number of drinking times and retention time in the oral cavity.

Objectives: The purpose of the study was to analyze the association between indirect vision skills and neck, shoulder, and back pain in dental hygienists. Methods: This cross-sectional study included 85 dental hygienists working full-time at dental clinics. A survey was performed for musculoskeletal symptoms in the neck, shoulders, and back of the subjects. The O'Connor tweezer dexterity test was performed using a mirror to evaluate their indirect vision skills. For statistical analyses, the t-test and one-way analysis of variance were performed. Results: The neck was the most common region of musculoskeletal pain (89.4%). The most intense pain was experienced in the neck (70.6%) and right shoulder (60.0%). Neck pain (20.0%) caused the most interference with clinical practice. Indirect vision skills were lower in the group with severe pain in the left shoulder or with high interference in work due to the left shoulder pain (p=0.026 and p= 0.017, respectively) or right shoulder pain (p=0.004). Conclusions: In this study, neck pain was a major musculoskeletal symptom among dental hygienists, and poor indirect vision skills were associated with the development of shoulder pain. Therefore, to prevent such musculoskeletal symptoms, dental hygienists should become proficient in indirect visualization, which enables a balanced and neutral posture.

This study aimed to investigate the medically inclined college students' knowledge, attitude, and compliance on the preventive behaviors of the Middle East respiratory syndrome (MERS). A cross-sectional study was conducted on 251 medically inclined college students in Jeonju Kijeon College from June 8 to 13, 2015, using a scale on the knowledge and attitude toward MERS and a structured questionnaire. The t-test, analysis of variance, and Pearson correlation coefficient were used to analyze the data. The participants consisted of 46.6% college students majoring in dental hygiene, 30.7% in clinical pathology, and 22.7% in emergency rescue, and 69.7% of them had been educated on MERS prevention. This study revealed that students who received MERS prevention training (t=3.457, p=0.001) and female students (t=-2.945, p=0.005) had more knowledge on MERS, while students from the dental hygiene department (F=8.048, p<0.001) and those in their third year (F=3.978, p=0.020) showed a more positive attitude toward MERS. Regarding the correlation between knowledge, attitude, fear of infection and compliance on the preventive behaviors, students were more knowledgeable (r=0.133, p=0.036), presented a more positive attitude (r=0.158, p=0.012) and had more fear of infection (r=0.312, p<0.001), were more likely to comply with the preventive measures. For an effective prevention of MERS, a newly found infectious disease, we suggest that medically inclined college students must improve their knowledge of and have a positive attitude toward MERS infection management at a medical institution in compliance with the MERS infection preventive behaviors. Furthermore, this study shows that an infection management education program should be developed, so that which students could learn about the causes, dissemination routes, and preventive methods of infectious diseases, including the newly discovered ones, prior to their clinical training at a medical institution.
