The purpose of this study was to evaluate self perception of occlusal status and recognition for orthodontic treatment as well as the prevalence of orthodontic treatment need objectively and subjectively. 3979 (male 2107, female 1872) school students of age 7~18 were analyzed by questionnaire and clinical examination and the results were as follows, 1. Perception of occlusal status on one's own was more generous than that of orthodontist's and it was affected by the factors such as age, patterns of malocclusion. 2. Recogniuon of subjective need for orthodontic treatment was more generous than that of objective need for the treatment, and factors such as age and sex of patient, parents' age and rate of education, income, occupation, classification of malocclusion and regional discrepancy were influenced. 3. Negative aspect of orthodontic treatment was influenced by the environmental factors. 4. A survey of want for orthodontic treatment showed one's alteration in recognition of the occlusal status with age and esthetic component was much more emphasized than functional component. 5. The multivariate discriminanat analysis for orthodontic treatment group showed that mother's rate of education, classification of malocclusion, demographic characteristics were critical in the determination of treatment group. 6. Test of inter-examiner reliability showed moderate coincidence.

To evaluate the oral health status and to assess the resultant dental treatment needs in adolescents, 2,062 adolescents aged 14-17 years attending middle and high schools in Yangsan were surveyed by clinical examination and questionnaires. The obtained results were as follows. In the dental caries examination based on WHO criteria, the treatment needs of 66.7% of the subjects were determined. Assessment of dental erosion by the VEDE system indicated the treatment needs in 27.8% of the subjects, while MIH examination based on EAPD criteria indicated the treatment needs in 14.7%. Assessment of malocclusion using the occlusal index showed good occlusion in 67.8%, no need for treatment in 19.7%, slight need for treatment in 6.8%, definite need for treatment in 4.5%, and worst occlusion in 1.1% of the subjects, showing 12.5% of average treatment need. The prevalence and treatment need for periodontal disease was found to be 71.2% by CPITN assessments. The assessment of temporomandibular disorders by Helkimo's anamnestic index showed no symptoms in 67.1%, mild symptoms in 13.4%, and severe symptoms in 19.5% of the examinees. The overall treatment need of TMD was 20.6%. Periodontal diseases were ranked the highest in treatment need, followed by dental caries, dental erosion, MIH, TMD, and malocclusion in order. The results of this study indicated the overall status of adolescents'oral health and dental treatment needs. These might hopefully provide fundamental data and contribute to establishing promotional projects for adolescent oral health in Korea.

This article discusses how to conduct treatment planning and decision making in special needs dentistry. Special needs patients often lack cooperative ability during dental treatment and have a deteriorated oral health status. To overcome the limitation in communication with special needs patients and solve their complicated dental problems, dentists need to have extensive preoperative information about the patients and their caregivers. Treatment procedures should be organized in a patient-centered and cost-effective manner. Additionally, clinical outcomes need to be predicted taking into consideration of the patients' condition. The clinical experience of committed dentists is another factor that enhances the benefits of extensive treatment in special needs patients with many limitations. The insightful treatment decision-making of dentists will contribute to improving the oral health of special needs patients despite the various obstacles.

Background: Atrial fibrillation (AF) is one of the most common complications after cardiac surgery. Several therapeutic and preventive strategies have been introduced for postoperative AF, but the treatment and prophylaxis of AF remain controversial. We aimed to compare the efficacy of intravenous amiodarone and oral propafenone in the treatment of AF after coronary artery bypass grafting (CABG). Methods: This was a randomized controlled trial performed in two hospitals in Shiraz, Iran from 2009 to 2012. We included all patients who underwent elective CABG and developed AF postoperatively. The patients were randomly assigned to receive propafenone or amiodarone. The duration of AF, the success rate of the treatment, the need for cardioversion, the frequency of repeated AF, and the need for repeating the treatment were compared. Results: The duration of the first (p=0.361), second (p=0.832), and third (p=0.298) episodes of AF, the need for cardioversion (p=0.998), and the need to repeat the first and second doses of drugs (p=0.557, 0.699) were comparable between the study groups. Repeated AF was observed in 17 patients (30.9%) in the propafenone group and 23 patients (34.3%) in the amiodarone group (p=0.704). Conclusion: Oral propafenone and intravenous amiodarone are equally effective in the treatment and conversion of recent-onset AF after CABG.

Objective: Our aim was to determine the correlation between dental treatment need as assessed by the components of the index of orthodontic treatment need (IOTN) and a self-evaluation questionnaire in a population selected from the dental clinics of Shiraz, Iran. Methods: The dental treatment needs of 240 participants (120 men and 120 women) were measured on the basis of the IOTN dental health component (IOTN-DHC), IOTN aesthetic component (IOTN-AC), IOTN AC determined by the examiner (IOTN-ACE), and a self-evaluation questionnaire (SEQ). The correlations between the treatment needs assessed by all the methods as well as the correlations of the treatment needs with age and gender were assessed using a Spearman's correlation coefficient (${\alpha}$ = 0.01). Results: All methods were significantly correlated ($p{\leq}0.001$). The associations of IOTN-ACE with IOTN-DHC and SEQ were moderately significant (rho = 0.49 and 0.41, respectively). The associations of IOTN-AC with IOTN-DHC and SEQ were weakly significant (rho = 0.24 and 0.35, respectively). The IOTN-DHC was moderately associated with SEQ (rho = 0.53). Gender and age were not associated with treatment needs estimated by any of the methods used ($p$ > 0.06). Conclusions: The correlations between the self-evaluation and the IOTN components in young adults were close to those reported in children, and IOTN-ACE was more reliable than IOTN-AC.

The aim of this study was to identify the risk factor related to the need for operative treatment and avoid unnecessary non-operative management for intussusception in children. We retrospectively reviewed medical records of patient treated for intussusception at our institution between January 2006 and January 2013. Clinical features such as gender, age, seasonal variation, symptoms and signs, treatment results were analyzed. Univariate and multivariate analyses including a chi-square test for categorical variables and logistic regression analysis were performed. During the study period, 356 patients were treated for intussusception. 328 (92.1%) was treated successfully by the non-operative pneumoreduction, and 28 (7.9%) required operative management. On univariate analysis, risk factors which were related to the need for operative treatment were age, vomiting, bloody stool, lethargy, and symptoms duration. A logistic regression analysis in order to assess for independent predictors of operative treatment was performed. Age (<6 vs ${\geq}12$ months) (OR 4.713, 95% CI 1.198~18.539, p=0.027) and symptoms duration longer than 48 hours (OR 4.534, 95% CI 1.846~11.137, p=0.001) were significantly associated with a requirement for operative treatment. We conclude that younger age and a longer duration of symptoms (${\geq}48$ hours) are the independent risk factor related to the need for operative treatment for intussusception. Early surgical intervention or transfer to a hospital with pediatric surgical capabilities should be considered for patients with these findings.
