This study was designed to investigate the status of orthodontic treatment and facial plastic surgery among 389 patients who visited dental clinics located in Seoul and Gyeonggi Province. After the collection of data, an analysis was carried out using a spss statistical program. The analysis results are as follows. the level of satisfaction with orthodontic treatment from patients with experience of the orthodontic treatment turned out to be high(p<0.01). Women considered 3.01 to 4 million won to be reasonable cost for orthodontic treatment (p<0.05), which is higher cost recognized by men, and patients with experience of orthodontic treatment recognized 19 to 24 months as the proper orthodontic treatment period(p<0.01). In addition, women showed higher figures than men in their awareness on the need for orthodontic treatment checkups(p<0.001), and facial plastic surgery experience (p<0.01). With respect to the part of the face on which they hoped to have plastic surgery, eye plastic surgery was higher in women (p<0.01), and nose surgery turned out to be higher in patients with experience of orthodontic treatment(p<0.05). Meanwhile, women considered the eye as the most important part among other facial areas (p<0.001), and they recognized that dentist should perform plastic surgery on both jaws among facial areas(p<0.01). In conclusion, the dental medical staff should provide consultations and operate treatment systems in consideration of gender differences and needs of dental patients. In the case of orthodontic treatment for the improvement of facial appearance, especially double jaw surgery which is closely related to the oral function, professional dental medical staff needs to perform the operation, considering the special oral environment. In addition, it is determined that provision of relevant medical information and promotion of dental service is required to provide patients with correct knowledge about orthodontic treatment and facial plastic surgery.

Objectives : The purpose of this study was to examine the knowledge of people in general about orthodontic treatment and their attitude to that by conducting a survey in a bid to provide information on the improvement of their incorrect awareness of orthodontics and on the development of clinical orthodontic treatment. Methods and Results : The subjects in this study were 389 people in general who resided in Seoul and Gyeonggi Province. A self-administered survey was conducted, and the findings of the study were as follows: 1. As for awareness of orthodontic treatment among the people in general by gender, the women knew better about orthodontic treatment than the men, and the gender gap was significant(p<0.05). 2. Concerning satisfaction with the shape and arrangement of the teeth by age, those who were in their 20s were most satisfied, and the teens were satisfied the least. There were significant gaps according to age (p<0.05). 3. As a result of checking the degree of their inconvenience about the use of chewing teeth by age, the people who were in their 30s felt the most inconvenience, and the gap between them and the others was significant(p<0.01). 4. As a result of asking them whether they had an intention to receive orthodontic treatment, the women had a more intention to do that than the men(p<0.001). By age, the younger respondents had a more intention, and the gaps between them and the others were significant(p<0.001). 5. As a result of analyzing their perception of the positives of orthodontics by gender, the women took a more positive view of it than the men, and their gap was significant(p<0.01). Conclusions : When orthodontic treatment or orthodontic treatment counseling is provided to orthodontic treatment patients or people in general in the field of clinical dentistry, it should be noted that the way patients and people in general look at orthodontic treatment is different according to their age and gender, and they should be informed of the positives of orthodontic treatment to step up the development of orthodontic treatment.

Purpose: The purpose of this study is to examine decision factors to start orthodontic treatment with male and female undergraduates having experience in orthodontic treatment at a dental clinic or hospital because of malocclusion. Methods: A survey was carried out to investigate decision factors to begin orthodontic treatment with 330 male and female undergraduates attending universities located in Daegu Metropolitan City or Gyeongsangbuk-do who had experience in orthodontic treatment at a dental clinic or hospital because of malocclusion, and out of 330 questionnaire sheets, total 294 (89.1%) sheets were employed for analysis after excluding ones unreliably or erroneously answered. Results: According to the results of analyzing decision factors for orthodontic treatment, such factors as 'a dentistry-related person's suggestion', 'feeling necessity on one's own' are found to be significantly higher in students majoring in health units than those having non-dental health majors, and students residing in small and medium cities are influenced more significantly by this decision factor, 'an acquaintance's suggestion', than those living in farming and fishing villages or big cities, and students who started orthodontic treatment at elementary school were more significantly influenced by the factor, 'feeling necessity through the public media'. Conclusion: Among the factors influencing their decision on orthodontic treatment, no influence was found in sexual difference, and each of the decision factors influenced them considerably according to the difference of their residence, economic power, majors, or time to start orthodontic treatment.

Orthodontic treatment for middle-aged patients has become more commonplace with various reasons including improved socioeconomic status. Understanding of oral status and treatment modalities of middle-aged patients is mandatory for accurate diagnosis and proper treatment planning. This study investigated 100 consecutive patients aged 40s and 50s and 100 aged 20s who had been examined and diagnosed at the Department of Orthodontics, Chonnam National University Dental Hospital. The results were obtained as follows; 1. Gender distribution showed female outnumbered male patients in young-aged adult patients, but middle-aged patients showed similar male and female distribution. 2. The major concern seeking orthodontic treatment was esthetics not only in young-aged but also in middle-aged adult patients, and a number of middle-aged patients were concerned about oral health as well. 3. Considerable number of middle-aged patients were referred by other dental specialties while young-aged adult patients were more self-motivated for orthodontic treatment. 4. Middle-aged adult patients had more missing teeth and periodontal disease than young-aged adults. 5. The most frequently-observed problem was dental spacing in middle-aged patients while dental crowding in young-aged adult patients. Middle-aged patients showed higher prevalence of deep overbite and overjet while most of young-aged adults presented opposite direction of problem in overbite and overjet. 6. Limited orthodontic treatment was required rather than comprehensive treatment in middle-aged patients, and the most common tooth moving area was anterior part of dentition in case of limited treatment. Need of interdisciplinary therapy with other dental specialties was more common in middle-aged patients. 7. Intervention of specific technique such as invisible TP, passive bracketing, passive wire bonding, and lingual orthodontics was more required in middle-aged patients. Considering that middle-aged patients have different characteristics than young-aged adults, the results of the present study suggest that different treatment modalities are required in middle-aged orthodontic patients in order to manage them properly and efficiently.

Objective: This paper describes changes in the characteristics of patients seeking orthodontic treatment over the past decade and the treatment they received, to identify any seasonal variations or trends. Methods: This single-center retrospective cohort study included all patients who presented to Seoul National University Dental Hospital for orthodontic diagnosis and treatment between January 1, 2005 and December 31, 2015. The study analyzed a set of heterogeneous variables grouped into the following categories: demographic (age, gender, and address), clinical (Angle Classification, anomaly, mode of orthodontic treatment, removable appliances for Phase 1 treatment, fixed appliances for Phase 2 treatment, orthognathic surgery, extraction, mini-plate, mini-implant, and patient transfer) and time-related variables (date of first visit and orthodontic treatment time). Time series analysis was applied to each variable. Results: The sample included 14,510 patients with a median age of 19.5 years. The number of patients and their ages demonstrated a clear seasonal variation, which peaked in the summer and winter. Increasing trends were observed for the proportion of male patients, use of non-extraction treatment modality, use of ceramic brackets, patients from provinces outside the Seoul region at large, patients transferred from private practitioners, and patients who underwent orthognathic surgery performed by university surgeons. Decreasing trends included the use of metal brackets and orthodontic treatment time. Conclusions: Time series analysis revealed a seasonal variation in some characteristics, and several variables showed changing trends over the past decade.

Objective: To determine the changes in dental anxiety, state anxiety, and trait anxiety levels of patients and their parents after 3 months of active orthodontic treatment. Methods: We evaluated 120 patients and one parent of each patient. State Anxiety (STAI-S), Trait Anxiety (STAI-T), and Corah's Dental Anxiety Scale (DAS) were administered before orthodontic treatment (T1) and after 3 months of treatment (T2). Differences in scores between T1 and T2 were compared using paired-sample t-tests and the relationship between the scores of the DAS and the STAI were analyzed using a bivariate two-tailed Pearson correlation test. Results: Dental anxiety and state anxiety levels decreased among the patients after adjustment to orthodontic treatment (p < 0.001). However, 3 months of treatment was not sufficient to decrease the anxiety levels of parents (p > 0.05). Patient trait anxiety affected patient state anxiety and dental anxiety (p < 0.01). Additionally, a significant correlation was found between patient dental anxiety and parent dental anxiety (p < 0.05). Conclusions: Dental anxiety and state anxiety levels decrease after patients become familiar with their orthodontist and they became accustomed to orthodontic treatment. However, 3 months is not a sufficient length of time to decrease parental anxiety levels.

Objectives: The purpose of this study is to investigate the relationship between perceived oral health, medical service satisfaction, and oral health impact profile (OHIP-14) and the factors affecting OHIP for orthodontic patients, and to provide basic data to improve the quality of life of orthodontic patients in accordance with oral health. Methods: The study explained the purpose and purport of this study to orthodontic patients who visit dental clinics located in Daejeon and Chungcheong province for about two months from July 01, 2019, and conducted a self‐reported questionnaire survey for 220 participants who agreed to participate in this study. of the collected questionnaires, data of 197 subjects were used for the final analysis except 23 that were inadequate. Results: As for orthodontic treatment satisfaction according to perceived oral health and OHIP, there was statistically significant difference between respondents who were 'very healthy' and 'not healthy' (p<0.05). The higher the supplementary service satisfaction, the higher the orthodontic treatment satisfaction, and the higher the perceived oral health, the OHIP was found to be the higher. The factors affecting OHIP were found to be significantly associated with orthodontic treatment satisfaction and perceived oral health. The explanatory power was 15.6%. Conclusions: Active and ongoing oral health education should be provided to dental hygienists to ensure that the patient's oral cavity is healthy, and although additional services need to be improved, it is more important to have management strategies for patients to improve orthodontic treatment satisfaction.
