Background: To evaluate orthodontic treatment need (OTN) in a juvenile populace, utilizing the Index of Orthodontic Treatment Need (IOTN), including sexual orientation contrasts evaluation.
Methods: The example involved 2250 young people, 13.1 - 17.4 years of age (mean age, 14 years and 6 months). The examinations were done on the study models and all encompassing radiographs taken from every subject. The dental health (DHC) and aesthetic (AC) segments of the IOTN were applied as an evaluation measure of the requirement for orthodontic treatment. The agreement (kappa measurements) was ascertained to examine the understanding between the DHC and the AC of the IOTN. Results: Utilizing the DHC of the IOTN, the extent of subjects assessed to have an incredible or extremely extraordinary treatment need was 28.7%, and 16.7% were in need (grades 8 - 10) as indicated by the AC (IOTN). No sexual orientation contrasts were noted, with the exception of no need class of the IOTN (more successive in young men) as per the DHC (chi-square: 6.83, df: 1, P = 0.01). There was a moderate agreement between the DHC and the AC of the IOTN (kappa = 0.49, 95% CI, 0.47 - 0.63).
Conclusions: Using the IOTN, approximately a third of theadolescent school children werebeing found to be qualified for treatment in open programs.

Background and aim: There are no strict criteria in determining the need for orthodontic treatment and dentists often have different opinion on assessing the orthodontic treatment needs. Making an appropriate estimation of the need and demand for orthodontic treatments is necessary to organize and provide meaningful orthodontic services. In this study, the orthodontic treatment needs were evaluated in highschool boys of Yazd.Materials and methods: 420 students who were studying in 14 different high schools were randomly selected. All participants were examined under normal white light and DHC(dental health component) ruler. To assess the orthodontic treatment needs, the dental health component of IOTN index was used. The data were analyzed by Chi-square test and p-value was 0.05.Results: Measurements showed that 44.8% of students scored 1, 15.1% scored 2, 13.6% scored 3, 15.3% scored 4 and 10.7% scored 5 in DHC records. The most frequent malocclusions observed in this study population were contact point displacement (27.3%), crossbite (13.3%), hypodontia (12.8%) and increased overjet (9.3%).Conclusion: Based on the results, approximately one fourth of participants had definite need for orthodontic treatments (IOTN Grades 4 and 5) which is a warning sign. More studies are needed to be done on different populations of the country to make the governors able for organizing oral health programs and providing beneficial dental insurance.

Aim: Occlusal indices used to determine orthodontic treatment needs cannot include the patients’ perception about their need for orthodontic treatment. That is why in some cases, these indices show that a particular patient needs orthodontic treatment while the patient feels no such need. This study was carried out to compare normative and self-perceived orthodontic treatment needs of 11-14 year-old school children.Materials and Methods: In a descriptive cross-sectional study 250 children of 11 to 14 years old were selected randomly. The scores of the Aesthetic Component (AC) of IOTN, were determined by specialist and the children themselves. The Dental Health Component (DHC) of IOTN was also assessed. Statistical analysis used: correlations between the AC of the patient, AC of the specialist and DHC of the specialist were assessed using Spearman’s rho correlation coefficient.
Results: The mean of patient’s AC and specialist’s AC were 2.556 and 4.308, respectively, while the mean of specialist’s DHC was 2.60. The correlation coefficient between patient’s AC and specialist’s AC was 0.281, between specialist’s AC and DHC was0.549 and between patient’s AC and DHC was 0.210. The highest correlation was seen between specialist’s AC and DHC and the lowest correlation was seen between patient’s AC and DHC.Conclusion: The significant positive relation between the AC indices and the DHC indicates their ability to determine the need for orthodontic treatment. The highest need for orthodontic treatment was determined by specialist’s AC and the lowest was patient’s AC.

Aim: Awareness of orthodontic treatment need is very important in hygienic planning and dentistry insurance. This study determined the rate of orthodontic treatment need based on IOTN index in 12-16 year old patients undergoing orthodontic treatment in 4 Tehran dental schools and 2 orthodontic private offices in 2004-2006.Materials and Methods: In this descriptive research, study casts and charts for 209 patients aging 12-16 in 4 dental schools of Tehran and 2 orthodontic private offices were surveyed based on IOTN index in different ages and in terms of gender. Classifications (CI,II,III), overjet, openbite, deepbite, crossbite, contact displacement, supernumerary, ankylosed, impacted and missing teeth, cleft lip, cleft palate and lip, cleft palate, and facial asymmetry were evaluated, and compared with IOTN results achieved from 22, educational districts of Tehran. Chi-square, Fisher's Exact and ratio equality tests were used to analyze the data.Results: Among 209 patients under treatment, 22.5% needed very severe treatment (grade5), 33% severe(grade4), 4.36% average (grade3) and 8.2% needed less or no treatment (grades1&2). The number of girls being treated was more than boys (66.5%); most of the patients under treatment were 12 years old (67 persons= 32.1%); the most common causes of orthodontic treatment were contact displacement 57.4%, overjet 22.5 and deepbite 17.7%.Conclusion: Regarding treatment need among patients under treatment, we concluded that most of the treated patients needed treatment based on IOTN and the number of patients needing simple treatment was very small, so treatment decisions were made according to IOTN.
