Objectives : The purpose of this study was to examine factors related to the satisfaction level of patients with dental services. Methods : The subjects in this study were 200 patients at three different dental clinics in South Gyeongsang Province, on whom a survey was conducted from June 1 to July 31, 2009. The collected data were analyzed, and the findings of the study were as follows. Results : In regard to the general characteristics of the patients investigated, the women(61.5%) out-numbered the men. By age, those who were at the age of 30 and down made up the largest age group(47.0%). By academic background, the greatest group received junior-college education(54.0%). By occupation, the company employees constituted the largest group (50.5%). By income, the greatest group earned an income of 2 to 2.99 million won(75.0%). Second, as to connections between the characteristics of dental treatment and the reason of choosing the dental clinics, the largest group(70.4%) chose the dental clinics by word of mouth or the recommendation of others. Concerning the reason of dissatisfaction, the biggest group(72.7%) was unsatisfied with medical costs. As for the degree of explicit complaint, the greatest group(49.7%) sort of complained about what made them dissatisfied. Regarding the type of treatment, the biggest group(49.0%) received prosthodontic treatment. In relation to fear for dental treatment, the largest group(34.0%) feared receiving the treatment, and the biggest group(42.6%) did that due to the sound of machines. Third, satisfaction with services(0.762) had the closest correlation to overall satisfaction level, followed by satisfaction with employees(0.735), satisfaction with dentists(0.644) and satisfaction with convenient facilities (0.579). Fourth, the factors that affected overall satisfaction level were gender, the reason of choosing the dental clinic, satisfaction with dentists, satisfaction with employees, satisfaction with services and satisfaction with convenient facilities. The patients who were better satisfied with services(p<0.001), who were more contented with dentists(p<0.001), who chose the dental clinics by the recommendation of others(p<0.01), who were male(p<0.05), who were more gratified with employees(p<0.05) and who were more contented with convenient facilities expressed better overall satisfaction. Conclusions : The above-mentioned findings suggested that dental institutions should keep track of the expectations of patients to prepare differentiated strategies for marketing and human-resources development in consideration of their own circumstances to boost the satisfaction level of patients. Specifically, it's required to heighten the satisfaction level of patients with dentists.

In clinical dentistry, botulinum toxin is generally used to treat the square jaw, bruxism, and temporomandibular joint diseases. Recently, this procedure has been expanded and applied for cosmetic purposes, and it is becoming a key task to be aware of the precise anatomical structure of the target muscles to be cautious during treatment and how to prevent side effects. Therefore, the purpose of this study is to observe the anatomical structure of the superficial layer of masseter muscle and to provide a most effective botulinum toxin injection method through clinical anatomical consideration. It was observed that the muscle belly of superficial part of the superficial layer was originated from the deep to the aponeurosis of masseter muscle and descend, then changed gradually into the tendon structure attaching to the inferior border of the mandible. In this study, we named this structure deep inferior tendon. This structure was observed in all specimens. We conclude that the use of superficial layer and deep layer injection should be considered to prevent paradoxical masseteric bulging in consideration of the deep inferior tendon of superficial part of superficial layer of masseter muscle.

The techniques of the dental treatment are well known to common people, but the dental implant as one of the treatment options to rehabilitate patient's mouth is little known to them. Taking these situation into consideration, we, writers made actual analyses of statistics by putting into the form of diagrams based on questionnaires. Three hundreds of common people over 20 years old were picked up and we used convenience sampling method which is one of nonprobability sampling methods. Statistics are about these questions. 1. How much common people know about dental implant as a treatment option. 2. How much common people know about the detailed portions of the dental implant for rehabilitaton. 3. How common people got to know the dental implant. We present actual answers of the common people.

Objective : To investigate the prevalence of dental anomalies and to determine the associations between dental anomalies in permanent teeth Materials and methods : The samples were 1,240 patients (760 females and 480 males, mean age=15.1 years) who visited the Samsung Medical Center. Dental anomalies were diagnosed using pre-treatment dental casts, radiographs, clinical examinations, and medical/dental histories. Prevalence and association were investigated according to gender and sidedness. The Chi-square test was performed for statistical analysis. Results : The most common missing tooth was the lower lateral incisor, followed by the lower and upper second premolars. This particular dental anomaly is characteristic of the East Asian population (prevalence of congenital missing tooth=12.3%). The upper anterior area was the most frequently affected area (prevalence of supernumerary tooth was 1.5%). The presence of a supernumerary tooth was more prevalent in males than in females (p<.05, odds ratio=3.2). The most frequently affected tooth was the upper canine (prevalence of impacted tooth=4.3%). Unilateral impaction of the upper canine occurred significantly more often compared to bilateral impaction (p<.001). The prevalence of peg lateralis was 2.7%. The presence of congenital missing tooth was closely associated with peg lateralis (p<.01). If children aged 7~8 years have peg lateralis, the rest of the teeth should be checked for congenital absences. Conclusion : The early detection of dental anomalies and understanding of their associations help clinicians determine the appropriate treatment timing and methods of dealing with these anomalies.

교정치료에 있어서 anchorage는 진단 및 치료계획에서부터 치료 종료 단계까지 교정의사가 항상 염두에 두면서 치료를 진행 해야 하는 중요한 요소이다. 환자의 적극적인 협조를 필요로 하는 전통적인 anchorage 조절법 보다는 miniscrew 같은 skeletal anchorage 가 좀더 효과적인 방법으로 제시되어 지고 있어, miniscrew의 교정적 이용 시 고려사항에 대하여 전반적인 고찰과 증례보고를 통해서 niniscrew의 다양한 임상적 적용에 대해서 살펴보았다. 또한 midpalate부위가 miniscrew의 식립 부위로서 가지는 장점과 식립 시의 주의사항을 알아보았으며 skeletal anchorage 가 교정에 도입되면서 치료개념과 방법에 있어서의 변화를 요약하면 다음과 같다. 1. 절대적인 개념의 Anchorage가 도입 되었다. 2. 생역학적 면에서 치아의 치체이동이 쉬워지고 determinate system이 설계되어 질수 있다. 3. 기존의 수술로만 가능했던 치료들 중 일부는 교정 치료만으로 치료가 가능하게 되었다.

Objectives: The objective of the study was to investigate the oral health index in orthodontic patients by dividing the patients into two groups; the OHCP (Oral Health Care Program)group and the control group. Methods: The subjects in Busan were divided into two groups, including the OHCP group (205 patients) and the control group (119 patients), during orthodontic treatment that took place from October 2015 to October 2016. The oral health index was subdivided into three groups according to the oral interest level of the OHCP and control groups. The oral health index used was Simplified Oral Hygiene Index (S-OHI) and Community Periodontal Index of Treatment Needs (CPITN). Results: When the degree of oral interest was compared, he OHCP group before application and after application saw a significant difference (p<0.001) in all the variables except the S-DI. Meanwhile, the control group saw no significant difference in most variables. after OHCP application, The OHCP group was significant differences in all variables (p<0.001), and the control group was no significant difference in most variables. Conclusions: Oral hygiene management for orthodontic patients should be systematically and professionally programmed differently from that for general dental treatment patients. As such, dental hygienists should take this into consideration and proactively develop and research programs similar to OHCP for orthodontic patients.

Ameloblastomaa are odontogenic benign tumors with epithelial origin, which are characterized by slow, aggressive, and invasive growth. Most ameloblastomas occur in the mandible, and their prevalence in the maxilla is low. A 27-year-old male visited our clinic with a chief complaint of the left side nasal airway obstruction. Three-dimensional computed tomography showed left maxillary sinus filled with a mass. Except for the perforated maxillary left edentulous area, no invaded or destructed bone was noted. The tumor was excised via Le Fort I osteotomy. The main mass was then sent for biopsy and it revealed acanthomatous ameloblastoma. The lesion in the left maxillary sinus reached the ethmoidal sinus through the nasal cavity but did not invade the orbit and skull base. The tumor was accessed through a Le Fort I downfracture in consideration of the growth pattern and range of invasion. The operation site healed without aesthetic appearances and functional impairments. However, further long-term clinical observation is necessary in the future for the recurrence of ameloblastoma. Conservative surgical treatment could be the first choice considering fast recovery after surgery and the patient's life quality.

Genioplasty may considerably change a person's face which needs surgical correction of deformed chin. Comprehensive treatment planning is therefore decisive for the treatment to be successful. A three-dimensional analysis of chin relative to cranial base, upper and lower jaws using the frontal and lateral facial photographs and cephalographs permits classification of the defective chin position and provides a basis for operation planning and deciding upon the operation method. A chin miniplate system has been developed for intraoperative registration securing the sagittal, vertical and horizontal position of the osteotomized chin and ould reduce the relapse rate.

The esthetic demands are growing in treatment of primary maxillary incisors as well as permanent ones. There is something dissatisfying about in the keen eyes of the pediatric dentists on their esthetic results of efforts because current tooth color system is created for the purpose of the application to the permanent incisors. In this study using the scientific color measurement device, I would like to introduce a color scheme for the primary maxillary incisors and suggest clinical tips for the better results of resin composite restorations.
