Interest in orthodontic treatment has increased. Consequently, the percentage of the orthodontic treatment in pediatric dentistry has also increased. Given this background, the purpose of this study was to analyze the characteristics and the trends of pediatric orthodontic patients of Chonnam National University Dental hospital. A total of 670 patients (349 male, 321 female) diagnosed with orthodontic problems during the period from January 1st, 2004 to December 31st, 2014, were analyzed. The number of pediatric orthodontic patients was high in January, February, July and August. When it comes to age, the percentage of the patients who were eighty-years old accounted for the largest age group with 19.6%, followed by seven-year, nine-year, ten-year, eleven-year, and six-year old age groups. Skeletal class 1 accounted for 48.1% of the total cases, followed by class 2 (28.7%) and class 3 (23.3%). Mesofacial type accounted for 65% of the total cases, followed by dolichofacial type (19.3%) and brachyfacial type (15.8%). The period of the first phase orthodontic treatment was steadily shortened from 30.4 months in 2004 to 11.5 months in 2013. The result of this study is expected to provide information of the pediatric orthodontic patients.

Surgical-orthodontic treatment is an increasingly more common dental procedure whose unique psycho-social or psychological feature has not been fairly quantified objectively. Since the treatment of a surgical-orthodontic (or orthodontic) patient is part science and part art, a subjective recognition of a patient about his or her own treatment may be more important than technical success during and after treatment. Therefore, the knowledge of the patient's underlying psychological status could be useful in the prediction of patient's response to surgical-orthodontic (or orthodontic) treatment. The purpose of this study was to investigate and evaluate the psychological difference between conventional orthodontic patient and surgical-orthodontic patient by using locus of control (LOC) examination. Locus of control scale has been proven to be extremely useful in the prediction of a variety of human behaviors. Two types of locus of control data (I-score, Internal locus of control score : I-score, External locus of control score) were obtained for 42 surgical-orthodontic patients and randomly selected 42 conventional orthodontic patients (as a control group) matched for age and gender. No statistically significant difference was observed in the scale of internal and external locus of control between the groups of surgical-orthodontic patients and conventional orthodontic patients. However, in the group of surgical-orthodontic patients, males showed lower E-score (external locus of control score, higher internal locus of control tendency) than females. The results of this study suggested that the psychological background of surgical-orthodontic patients, in contrast with that of cosmetic surgery patients, has a similar disposition with that of orthodontic patients.

Objective: The purpose of this study was to evaluate the efficacy of a slim bristled toothbrush compared with a V-shaped orthodontic toothbrush in patients with fixed orthodontic appliances. Methods: Thirty four orthodontic patients receiving edgewise treatment were randomly assigned to two groups, a slim bristled toothbrush (Nano silver slim care) and a V-shaped toothbrush (Oral-B). Plaque index, gingival index and bleeding index were recorded at the beginning of the study (baseline), 2 weeks, 4 weeks and 6 weeks after new toothbrushes were supplied and the results were analyzed statistically. Results: No statistically significant differences were found for plaque index, gingival index and bleeding index between toothbrush groups during the 6 weeks. Plaque and gingival indices were decreased at 2 weeks and 4 weeks but increased at 6 weeks in both toothbrush groups. Bleeding index in the V-shaped toothbrush group showed the lowest value at 2 weeks then increased at 4 weeks and 6 weeks but in the slim bristled toothbrush group decreased from 2 weeks through 6 weeks to under baseline levels. Patients in their twenties had significantly lower values than teenagers in the slim bristled toothbrush group (p < 0.013). Conclusions: The results would suggest that both of the toothbrushes are equally effective but the use of a slim bristled toothbrush may be of benefit in promoting gingival health for fixed orthodontic appliance patients in their twenties and over.

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.

This study is aimed at providing the variables associated with adolescent compliance In orthodontic treatment, and identifies the salient predictors of cooperative behaviors over the course of treatment. Orthodontic attitude scale, orthodontic locus of control scale and demographics data were obtained for 60 adolescent orthodontic patients who had been in treatment a minimum of 10 months. This data was then analyzed in relation to their sex, school age and treatment compliance. The following results were obtained. 1. The scoring of external-powerful others-parents, subscale of the Orthodontic Locus of Control scale, found a statistically significant difference between sex differences (p<0.05). The score of boys was higher than that of girls. 2. The external-powerful others-parents score from the Orthodontic Locus of Control scale showed a significantly positive correlation (p<0.05) with the level of compliance. 3. The salient factors associated with compliance were the adolescent patients' own cognition and decisions. 4. There was a statistically significant correlation between the length of treatment and patient compliance (p<0.05). Thus, there was a substantial decrease in the cooperation of orthodontic patients over time. 5. Other independent variables including age, sex, family environment, religion, academic standing, parents' occupation and education, and brushing frequency were investigated and did not yield any significant relationships. Patient compliance is a critical factor in the efficacy of orthodontic treatment. Individuals vary greatly in their perceptions and attitudes of orthodontic treatment, sociodemographic environments and personality characteristics. In assessing the level of compliance attainable by each individual patient it is advisable To pay sufficient attention not only to the technical matters but also to the psychologic aspects of the treatment progress.

During diagnostic process of the orthodontic patients, it is not unusual to find canine impaction. Generally, the chief complaint of the patients is crowding or antetior crossbite which is not related with canine impaction, but sometimes they complainted delayed eruption of the canine or deviation of the adjacent teeth caused by canine impaction. Orthodondists have to make the proper treatment plan according to final treatment goals. On the following cases, two patients were diagnosed as a malocclusion with canine impaction, and were treated by different accesses, one by extraction, and the other by non-extraction each.

The concept of extraction in orthodontic treatment has been changed many times. Even today, criteria of extraction or nonextraction is still changing. In this study, changes depending on the evaluator's perception of treatment outcomes were compared in both extraction and nonextraction cases. In this study, premolar extracted 59 patients and nonextracted 60 patients, totally 119 patients who finished orthodontic treatment in Dankook University Dental Hospital orthodontic clinic were enrolled. Evaluation sections made up of specialists and laypersons assessed soft tissue traced from lateral cephalometric radiographs with visual analogue scale before and after the treatment. And the results were statistically analyzed. Thus, the conclusions drawn are as follows: 1. Average score is 5.76 in extraction, which is larger than 5.28 of nonextraction case. Improvement of facial profile was more favorably accepted in extraction case. 2. 5.875 in the group of specialists were higher evaluation than 5.165 in the group of layperson. 3. Specialists gave significantly higher ratings in the extraction than nonextraction. 4. A higher rating in extraction case of the layperson group has no significant difference with nonextraction case. 5. Nonextraction patients were given higher ratings from specialist group. 6. A higher rating of specialist group in extraction case has no significant difference with layperson group.

Distributions trends were examined in 9159 malocclusion patients who had been examined and diagnosed at Department of Orthodontics, College of Dentistry Yonsei University over a 6 year-period from 1992 to 1997. The results were as follows ; 1. The total number of orthodontic patients in 1997 increased in comparing with that of 1992(86%) and after 1995, the number of annual patients showed an increase. 2. Age distribution had shown over-19 year-old group being the largest(39.9%) but percentages of pre-adolescent patients had been decreasing while that of adult patient had gradually increased. 3. Distributions in the types of malocclusion, the Angle's Classification had shown : 33.3% for Class I, 28.6% for Class II and the largest 38.1% for Class III. 4. Among Class I patients, crowding showed the largest(32.6%) and protrusion group had gradually increased to 33.9% in 1996. Otherwise openbite and crossbite groups tend to decrease, annually. 5. Geographic distribution showed a majority of patients from Seoul(above 70%). Among the patients from Seoul, group within the distance 3-6Km from Yonsei dental hospital was the largest(32.3%) and group within 9Km showed 69% of total patients.

Eye examination was performed for diagnosis accommodative and binocular dysfunction. The prevalence rates were similar to other studies, therefore patients required not just the correction of the refractive error but a specific treatment for each diagnosed problems. Two symptomatic(diplopia, asthenopia, and intermittent blur) patients diagnosed as a convergence insufficiency was given full correction with visual training for 4weeks. They had a one or mixed binocular problems included accommodative insufficiency. Following 4 weeks later, visual training was effective to Improve convergence and suggest that continuous observation is necessary.

The purpose of the present study was to determine the effect of a 4 week course of Cox distraction manipulation (CDM) combined with therapeutic modalities on the treatment of patients with L4-5 herniated nucleus pulposus (HNP). A total of 15 patients with L4-5 HNP (mean age, 37.76 years; age range 20-50years) participated in the study. A 4 week course of CDM combined with therapeutic modalities was delivered to the patients for 6 days per week for the first two weeks, and three times per week for two additional weeks. The entire treatment consisted of 18 visits over 4 week period. Comparisons of changes in the muscle strengthening (MS), straight leg raise (SLR), and oswestry disability index (ODI) at pre-intervention, after two weeks treatment sessions, and at discharge (after 18 treatment sessions) were analyzed. Comparisons of changes in the disc herniation index (DHI) at pre-intervention and at discharge were analyzed using the paired t-test. There were significant improvements in the outcome measures of MS Ibs, SLR test, and ODI score after 2 weeks and 4 weeks sessions of CDM combined with therapeutic modalities as compared with the pre-intervention. However, no significant different pre-test and post-test DHI. CDM combined with therapeutic modalities appears to be a safe and efficacious, noninvasive treatment modality for patients with L4-5 HNP.
