Object : This cross-sectional study was performed in order to evaluate the prevalence of tardive dyskinesia among the hospitalized schizophrenic patients. Methods : Four hundred nineteen hospitalized schizophrenic patients(male=263, female=156) were recruited for this study. They were treated with antipsychotics for more than 3 months. The prevalence of tardive dyskinesia was assessed by the Abnormal Involuntary Movement Scale. Results : The prevalence of tardive dyskinesia was 35.6%(Male=36.9%, Female 33.3%). There were no significant differences in the prevalence of tardive dyskinesia among male and female schizophrenic patients. The prevalence of tardive dyskinesia among the patients over 30years old was much higher than those below 30years old. There were no significant correlations between the prevalence of tardive dyskinesia and the duration of hospitalization, the total amount of antipsychotics. The frequently involved parts of the body in the schizophrenic patients who have tardive dyskinesia were tongue, upper extremity, lips and perioral area, jaw, lower extremity, muscles of facial expression trunk, respectively. Conclusions : There was significant correlation between the age and the prevalence of tardive dyskinesia in the antipsychotic-treated schizophrenic patients. There were no correlations between the prevalence of tardive dyskinesia and gender difference, the duration of hospitalization, the total amount of antipsychotics.

Background: Two-jaw surgery including mandibular and maxillary backward movement procedures are commonly performed to correct class III malocclusion. Bimaxillary surgery can reposition the maxillofacial bone together with soft tissue, such as the soft palate and the tongue base. We analyzed changes of pharyngeal airway narrowing to ascertain clinical correlations with the prevalence of snoring after two-jaw surgery. Methods: A prospective clinical study was designed including a survey on snoring and three-dimensional (3D) computed tomography (CT) in class III malocclusion subjects before and after bimaxillary surgery. We conducted an analysis on changes of the posterior pharyngeal space find out clinical correlations with the prevalence of snoring. Results: Among 67 subjects, 12 subjects complained about snoring 5 weeks after the surgical correction, and examining the 12 subjects after 6 months, 6 patients complained about the snoring. The current findings demonstrated the attenuation of the largest transverse width (LTW), anteroposterior length (APL), and cross-sectional area (CSA) following bimaxillary surgery given to class III malocclusion patients, particularly at the retropalatal level. The average distance of maxillary posterior movements were measured to be relatively higher (horizontal distance 3.9 mm, vertical distance 2.6 mm) in case of new snorers. Conclusions: This study found that bimaxillary surgery could lead to the narrowing of upper airway at the retropalatal or retroglossal level as well as triggering snoring in subjects with class III malocclusion. Based on the current clinical findings, we also found that upper airway narrowing at retropalatal level may contribute to increasing the probability of snoring and that polysonography may need to be performed before orthognathic surgery in subjects with class III malocclusion.

Purpose: Torus palatinus is a bony prominence at the middle of the hard palate. The size varies from barely discernible to very large, from flat to lobular. This oral exostosis is not a disease or a sign of disease, but if large, may be a problem. So, we present the clinical and histopathologic features and applied therapy and provide a comprehensive review of the rare case of the symptomatic exostoses. Methods: A 37-year-old woman had slowly growing exophytic nodular mass of the bone that arises the midline suture of the hard palate. The patient was concerned about discomfort associated with movement of her tongue and about frequent irritation of the palatal mucosa during mastification of the hard food. The patient had a large, unilobulated torus palatinus. It extended from the area adjacent to the canine to a point beyond the junction with the soft palate. The mass was oblong in shape, measuring about 3 cm long, 2 cm wide, and 0.8 cm in height. Results: Before surgical intervention a CT was obtained for the sake of estimating the thickness of the bone between the exostoses and the maxillary antrum and floor of the nose. The surgical procedure was performed with the patient under general anesthesia. Removal of the exostosis was performed after midline mucoperiosteal incision with osteotome and diamond burr. Histologic finding revealed decalcified dense bony tissue, the presence of lacunae, and normal osteocytes. Conclusion: Surgical removal is recommended when one or more of the following condition exist: interference with the construction of prosthesis, interference with oral function, irritation or pathology of the overlying tissue, inability of the patient to maintain proper oral hygiene, and fear of malignancy or other psychologic trauma. We report a rare case of the torus arising in hard palate with symptoms.

The purpose of this study is to provide the general history of fostering dentists in Japan and introducing their new roles. This research was conducted based on the government policy report on dentists and the information published by each educational institution. Based on the collected data, the official websites were used to represent the latest statistics of the institutions. The number of dentists in Japan has increased. The government established the National Examination for Dentists to guarantee the quality of dentists. After the standards for developing questions for the national examination were established in 1985, the contents of the examination have been appropriately improved by revising the standards every four years. This improvement has required dental students to study a variety of subjects for six years at dental school. Since dentists in Japan are required to respond to various demands from the nation; the Model Core Curriculum for Dental Education was developed to teach medical ethics and abilities to ensure that dentists conduct themselves professionally. Recently, the roles of dentists have been changing in Japan. When providing dental services to older patients over the age of 65, dentists and other dental professions focus on maintaining oral functions, such as saliva secretion, bite force, tongue movement, and masticatory/swallowing functions. However, oral function-related services for children are different. In addition to providing essential dental services, dental practitioners also provide special treatment, such as oral muscle training, myofunctional therapy, health guidance, and space retainers to the child patients with developmental insufficiency in oral functions. Dentistry in Japan has undergone numerous changes over the years and has continued to offer high-quality dental health services. Thus, information gained from the Japanese experience may be helpful to dental professions in other developed countries for planning oral health measures.

Purpose: The purpose of this study was to investigate changes in the position of the hyoid bone and soft palate and the amount of airway space after bilateral sagittal split ramus osteotomy (B-SSRO). Methods: This study is a review of lateral cephalometric tracings of 30 patients who underwent B-SSRO with setbacks at Kyunghee Dental Hospital from 2005 to 2009. Lateral cephalograms were taken before (T0), within one month (T1), and more than six months after the surgery (T2). Results: The hyoid bone at T1 changed significantly towards the inferoposterior position. At T2, it had significantly moved superiorly, but not anteriorly. At T1, the nasopharyngeal space, extending from the posterior nasal spine to the posterior pharyngeal space, decreased significantly, but did not show a significant increase at T2. The nasopharyngeal space, extending from the middle of soft palate to the posterior pharyngeal space, decreased significantly at T1, but did not show a significant decrease at T2. The oropharyngeal airway space decreased significantly at T1 and did not return to its original position at T2. The hypopharyngeal space, extending from the anterior to the posterior pharyngeal space at the level of the most anterior point of the third cervical vertebrae, slightly decreased at T1, but the amount was insignificant; however, the amount of decrease at T2 was significant. The hypopharyngeal space extending from the anterior to the posterior pharyngeal space at the level of the lowest point of the third cervical vertebrae, decreased significantly at T1 but returned to its original position at T2. Conclusion: B-SSRO changes the position of the hyoid bone and muscles inferoposteriorly. These change allows enough space for the tongue and prevent airway obstruction. Airway changes may be related to post-operative edema, posterior movement of the soft palate, anteroposterior movement of the hyoid bone, or compensation for decreased oral cavity volume. The position of the pogonion which measures anterior relapse after surgery did not show significant differences during the follow-up period.

It is necessary that current oral health education should be not only focused on grade schoolers, but provided for even junior and senior high schools on regular basis in favor of higher level of knowledge about dental health and the habituation of oral health promotion behaviors. So this study took total 288 respondents as sample from Grade 3 of 'C' high school(Suncheon city, Jeonnam) to examine their experiences in oral health education, their awareness of needs for oral health education and their demands for oral health education in the interest of providing basic materials for effective oral health education. 1. As the result of researching health awareness, 13.9% respondents answered that they didn't have good total body health, while 33.3% respondents felt that they didn't have good oral health. That is, more respondents felt that their oral health is not good, rather than total body health is. 2. For daily toothbrushing frequency, it was found that most respondents(62.6%) brushed their teeth 3 times a day, And for toothbrushing methods, it was found that 35.5% used manual toothbrushing(up-and-down toothbrushing movement) and 30.0% used semi-automatic toothbrushing(rotational movement). On the other hand, majority(89.4%) of respondents conducted tongue brushing, but only 10.8% benefited from dental examination on regular basis. 3. 28.1% respondents had experiences in oral health education. Out of them, 69.3% felt moderate satisfaction at the education. Majority(91.2%) of respondents were instructed once in oral health education, and 82.7% respondents were instructed in the oral health via practices(toothbrushing guidance). 77.8% respondents were instructed in the oral health at dental clinics. 4. As the result of surveying demands related to oral health education, 92.3% respondents answered that they need regular oral health education, and 82.9% respondents answered that they need oral health technicians in school. And 87.8% respondents needed individual oral health education for the benefit of better oral health.

어린이의 공간유지와 교합유도의 치료를 위하여 가철성 장치는 소아치과 임상에서 일상적으로 사용되고 있다. 상악의 경우와는 달리 하악에서는 가철성 장치를 사용하는데 있어 유지력의 저하에 따른 치료효과의 감소, 환자의 불편감과 거부감으로 인한 미착용 등의 문제가 흔히 발생한다. 이것은 유치열기나 초기 혼합치열기 어린이의 경우, 하악구치부의 undercut양이 충분치 못함에도 불구하고, 여기에 협측 undercut으로부터 유지력을 얻는 각종 clasp를 적용하기 때문으로 사료된다. 또한 전통적인 가철성 장치들의 acrylic base plate가 설측에 위치하고 있어 설측 연조직이나 치조능 undercut과 많은 문제를 일으키는 현상을 볼 수 있다. 어린이들은 하악 장치의 작업모형을 위한 인상채득과정에서 술자의 지시대로 혀를 바르게 거상하지 못하는 예가 많은 것도 그 원인요소로 들 수 있다. 본 연구는 전통적인 하악의 Hawley acrylic plate로부터 clasp와 acrylic baseplate의 위치를 바꾸어 협측 base plate와 설측 clasp을 이용한 buccal acrylic appliance를 유치열기 및 초기 혼합치열기 어린이의 구강에 적용하여 그 장단점을 조사하고 환아들의 수용도와 효율성을 기존의 lingual acrylic appliance와 비교, 검토할 목적으로 시행되었다. 공간유지 및 치아이동을 필요로 하는 5개 증례를 대상으로 각 증례에 buccal acrylic appliance와 기존의 lingual acrylic appliance를 모두 적용하여, 유지력, 환자 수용도, 혀의 기능과의 조화, 치료 효과 등의 측면을 상호 비교해 보았다. 조사 결과, 조사 대상의 모든 증례에서 유지력과 환아의 수용도 측면에서 협측 장치가 설측 장치에 비해 월등히 우수한 것으로 나타났다. 또한 치료 효과의 측면에서도 협측 장치는 설측 장치와 유사한 것으로 나타났다. 본 연구를 통하여 하악에 가철성 장치를 사용할 경우, 전통적인 설측 장치와 관련된 각종 부작용을 해결하는 데에 buccal acrylic appliance가 훌륭한 대안으로서 임상적용을 추천할 만 하다고 사료되었다.
