Patients who have extruded anterior teeth and deep bite with pathologic tooth migration, it is necessary not only periodontal treatment for reduce inflammation, but also orthodontic treatment for intrusion of anterior teeth. However, it is difficult to place the orthodontic brackets due to the deep bite, and there is a problem that the extrusion of the posterior teeth occurs more easily than the intrusion of the anterior teeth biomechanically. In particular, in patients with long face, relative intrusion of the anterior teeth by extrusion of the posterior teeth causes the clockwise rotation of the mandible and makes the facial profile worse. Therefore the biomechanical consideration and appliance design that can block these problems are required from the treatment plan. This is a patient who had a deep overbite with extruded anterior teeth, treated by periodontal treatment and intrusion of mandibular anterior teeth using cute brackes and miniscrews, and resulted in favorable maintenance during 8-year retention.

The purpose of this study was to assess the level of awareness regarding the relationship between systemic diseases and oral health and the importance of education related to this association among dental patients, as well as to identify factors that affect the awareness of the relationship and the perceived need for education. This study was conducted from June 2016 to February 2017. Subjects of this study included outpatients (20-60 years old) from a dental clinic, and only patients who agreed to the survey were included. A total of 110 subjects were included, but the final analysis was based on 92 questionnaires, excluding questionnaires that were inaccurate. Survey questionnaires were completed by self-report and face-to-face interviews with a dental hygienist. The questionnaires covered basic information, awareness of the association between general and oral health, and experience with, and need for education related to, this association. Among the subjects, 48.9% were aware of the association between systemic diseases and oral health. A total of 39.1% of subjects had received education regarding the relationship between systemic diseases and oral health. Subjects who visited dental clinics regularly were 3.94 times (95% confidence intervals [CI]: 1.21-12.84) more likely to be aware of the association between oral health and disease compared with subjects who made only irregular visits to dental clinics. In addition, experience or education was significantly associated with awareness of the relationship between oral health and disease (odds ratio [OR]: 4.64, 95% CI: 1.54-13.93) and the need for education (OR: 3.98, 95% CI: 1.20-13.12). Thus, the dental professionals should provide education on the relationship between oral health and systemic disease in dental clinics to improve patients' awareness and oral health behaviors. These results can be used to strengthen education in the dental clinic.

The purpose of this study was to examine the perceptions, precedent tasks, positive and negative effects, and expandable professional tasks regarding the inclusion of dental hygienists (DHs) in the category of medical personnel. This study involved a survey of 259 DHs and 128 dentists. The findings were as follows: 94.2% of DHs and 46.9% of dentists were aware of inclusion in the category of medical personnel; 95.0% of DHs and 64.1% of dentists supported the idea; and 84.9% of DHs and 51.6% of dentists recognized its legitimacy. As for precedent tasks for inclusion in the category of medical personnel, both DHs and dentists scored high points in professional consciousness in the area of occupation. Both DHs and dentists scored the highest points in the quality management of DH education and the lowest points in the unification of school systems in the area of institution. In the area of society, DHs scored high points in the persuasion of the central government, whereas dentists scored high points in collaboration among concerned organizations. Regarding the positive effects of inclusion in the category of medical personnel, both DHs and dentists scored the highest points in the expanded perception of DHs. As for its negative effects, DHs scored high points in the aggravation of salary increase, whereas dentists scored high points in the aggravation of salary increase. Regarding expandable professional tasks after the inclusion of DHs in the category of medical personnel, the management of independent periodontal care programs recorded the highest percentage both in DHs and dentists. These findings highlight the need for adequate discussions about the meanings of the inclusion of DHs in the category of medical personnel and will hopefully contribute to the rational adjustment and legalization of DHs' works with regard to their inclusion in the category of medical personnel.

The aim of this study was to investigate the oral health problems among type 2 diabetes patients and suggest basic data for the promotion of their body and oral health by emphasizing the correlation between hemoglobin A1c and subjective oral health status. For 174 patients with type 2 diabetes and who were older than 40 years old, the questionnaire and measurement of hemoglobin A1c were conducted from January 9, 2012 to March 9, 2012. The results of the study were as follows. 1. They tended to be most aware of the following; 'inflammation on the oral mucosa' and 'pain on the oral mucosa' among the symptoms of oral mucosa, 'gum bleeding when brushing teeth' among the symptoms of periodontal disease, and 'feels dry in general' among the symptoms of xerostomia. 2. The patients with longer duration of diabetes showed greater recognition with regards to the symptoms of oral mucosa disease, periodontal disease, and xerostomia (p<0.05). 3. The group with regular meal showed lower level of hemoglobin A1c (p<0.001). 4. The level of hemoglobin A1c was higher in the group that recognized 'burning sensation', 'gum bleeding', 'gum recession' and 'bad breath' (p<0.05) as well as in the group that responded 'get up at night to drink' among the symptoms of xerostomia (p<0.05). Especially the symptoms of periodontal disease were revealed to be a factor that showed the 3rd strongest correlation with hemoglobin A1c.
