Objectives: This study is to assess the correlation of the changes in dental health-related quality of life before, during, and after orthodontic treatments in the patients. Methods: The self-administered survey was conducted in the patients who completed orthodontic treatments living in Seoul and metropolitan areas using Oral Impact on Daily Performances (OIDP) to identify the relevant factors. Data were analyzed with descriptive statistics of variables, independent t-test, one way ANOVA, and multiple regression analysis. Results: From observations of OIDP before, during, and after orthodontic treatment, discomfort associated with three factors including physical, psychological and social ones showed the statistically significant increases during orthodontic treatment than before the treatment; whereas, it was dramatically dropped afterward. Multiple regression analysis to find the influential factors of satisfaction level on orthodontic treatment by setting before, during, and after OIDP as independent variables and satisfaction on orthodontic treatment as a dependent variable revealed that OIDP before orthodontic treatment and after orthodontic treatment significantly affected satisfaction on orthodontic treatment. Conclusions: The above analysis on the change in patients' dental health-related quality of life showed that the quality of life improved after the orthodontic treatment. Accordingly, patients' quality of life and satisfaction level on orthodontic treatment are expected to improve if they strive to maintain healthy dental health through orthodontic treatment.

The purpose of this study was to provide basic data on counseling, education, and treatment related to orthodontic practices through an understanding of the relationships between orthodontic treatment, oral health-related quality of life, and happiness of high school students. The subjects in this study were 500 students in Grades 1~3 of a high school in Jeollabuk-do. We conducted a survey targeting this group; the results revealed the following: in the social support item, peer support showed significant differences in the matter of orthodontic treatment (p<0.05). In oral health-related quality of life, the students without orthodontic treatment showed 14.09 scores that were higher than the students with treatment (p<0.05). Regarding happiness, the students with orthodontic treatment showed higher scores which were significantly different from the those of the non-orthodontic treatment group (p<0.05). Additionally, upon examining the correlations between self-esteem, social support, oral health-related quality of life, and happiness, oral health-related quality of life, peer support, and happiness showed the negative (-) correlations while the rest of the variables showed the positive correlations (p<0.05). The factors having effects on oral health-related quality of life included the stress, matter of orthodontic treatment, and teachers support (p<0.05). The factors having effects on happiness included self-esteem, peer support, and family support (p<0.05). Based on the above results, even though dental orthodontic treatment had negative effects on oral health-related quality of life, it had positive effects on happiness. Consequently, it would seem necessary to seek active methods to increase oral health-related quality of life. This improvement could be achieved by minimizing inconveniences, such as mastication, in the process of dental orthodontic treatment, and developing programs that could enhance happiness.

Objective: The purpose of this study was to evaluate the effect of malocclusion or orthodontic treatment on oral health-related quality of life (OHRQoL) in adults. Methods: The sample consisted of 860 adults (378 men and 482 women, aged 18-39 years) who were clinically evaluated for malocclusion or orthodontic treatment experience. Participants were divided into 4 groups as follows: normal occlusion, malocclusion, fixed treatment, and retention. OHRQoL was assessed with the short form of the Oral Health Impact Profile (OHIP-14) and Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). Results: The malocclusion group and the fixed treatment group had significantly higher OHIP-14 scores than the normal occlusion group and the retention group (p < 0.001). The malocclusion group had the highest PIDAQ score, while the normal occlusion group and the retention group had the lowest PIDAQ score (p < 0.001). Women had higher OHIP-14 and PIDAQ scores than men. A significant positive correlation was found between OHIP-14 and PIDAQ scores (p < 0.01). Conclusions: Malocclusion has a negative impact on OHRQoL, but this could be improved in adults through orthodontic treatment. These OHRQoL questionnaires can provide additional useful information on specific aspects of orthodontic patients' psychological state.

The purpose of this study was to examine the influence of type of malocclusion and orthodontic treatment awareness on quality of life among orthodontic patients in the region of Busan as well as to develop an educational program tailored to the type of malocclusion as a way to improve quality of life. A survey was conducted for approximately 6 months from December, 2015, and the answer sheets from 472 respondents were analyzed. The most common painful area was the teeth, and this case was most predominant in the respondents with level 2 malocclusion, who differed from others in that regard (p<0.001). Regarding the relationship between satisfaction with orthodontic treatment and quality of life, respondents who were more satisfied currently and who were neither quite confident nor quite unconfident were ahead of their counterparts in quality of life. Concerning the reason for receiving orthodontic treatment, quality of life was lower among patients who started to receive treatment due to pronunciation problems (p=0.013), chewing difficulty (p<0.001), and temporomandibular joint click sound (p<0.001). With regard to influential factors on oral health-related quality of life, time for starting to receive orthodontic treatment was most influential (p<0.001), followed by current satisfaction (p<0.001), changes in confidence (p=0.003), self-rated teeth status (p=0.008), and type of occlusion (p=0.019). Therefore, accurate analysis of the oral health status of orthodontic patients and customized oral health education are required to improve quality of life even during the period of orthodontic treatment.

The present study surveyed 300 adults who completed orthodontic treatment to determine their oral health-related quality of life and changes in oral health behavior in orthodontic patients. The collected data is analyzed using the spss 22.0 program. Before orthodontic treatment, social factors (4.68) had the lowest associated quality of life score, and after orthodontic treatment, socially related quality of life showed the highest increase at 3.72 points. Changes in oral health behavior showed that many phosphorus scaling increased by 1.28 points after correction compared to before correction. As oral health quality of life and oral health behavior have changed through orthodontic treatment, dental professionals need to take appropriate management of each patient's individual quality through health education. Appropriate management needs to be developed.

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.

Purpose : This study was designed to compare the effective doses from low-dose and standard-dose multi-detector CT (MDCT) scanning protocols and evaluate the image quality and the spatial resolution of the low-dose MDCT protocols for clinical use. Materials and Methods : 6-channel MDCT scanner (Siemens Medical System, Forschheim, Germany), was used for this study. Protocol of the standard-dose MDCT for the orthodontic analysis was 130 kV, 35 mAs, 1.25 mm slice width, 0.8 pitch. Those of the low-dose MDCT for orthodontic analysis and orthodontic surgery were 110 kV, 30 mAs, 1.25 mm slice width, 0.85 pitch and 110 kV, 45 mAs, 2.5 mm slice width, 0.85 pitch. Thermoluminescent dosimeters (TLDs) were placed at 31 sites throughout the levels of adult female ART head and neck phantom. Effective doses were calculated according to ICRP 1990 and 2007 recommendations. A formalin-fixed cadaver and AAPM CT performance phantom were scanned for the evaluation of subjective image quality and spatial resolution. Results : Effective doses in ${\mu}Sv$ ($E_{2007}$) were 699.1, 429.4 and 603.1 for standard-dose CT of orthodontic treatment, low-dose CT of orthodontic analysis, and low-dose CT of orthodontic surgery, respectively. The image quality from the low-dose protocol were not worse than those from the standard-dose protocol. The spatial resolutions of both standard-dose and low-dose CT images were acceptable. Conclusion : From the above results, it can be concluded that the low-dose MDCT protocol is preferable in obtaining CT images for orthodontic analysis and orthodontic surgery.
