The Index of Orthodontic Treatment Need (IOTN) was used to assess the need for orthodontic treatment before and after treatment, on a systematic sample of 1225 cases. On the whole, full upper and lower fixed appliances brought about a greater improvement in Aesthetics and Dental Health Components compared to other appliance techniques, and were less likely to make the occlusion worse. It was found that certain occlusal traits were more likely to be successfully treated than others. A common problem resulting from treatment was the development of a cross-bite.

Aim The aim of this study was to determine the possible effects of the 2006 National Health Service General Dental Services contract changes on the referral pattern to the orthodontic department at St George's Hospital, South West London. Method This study was carried out on a retrospective basis. The notes of consecutive patients referred between 1st May and 30th September in 2005 and 2008 were assessed, and the patient's Index of Orthodontic Treatment Need (IOTN) and the source of referral noted. Results The total numbers of referrals increased from 260 in 2005 to 405 in 2008. The number of referrals from general dental practitioners decreased slightly from 165 to 156, as did the numbers of referrals from other sources, such as tertiary referrals. The number of referrals made by specialist practitioners increased from 41 in 2005 to 207 in 2008, representing an increase from 16% to 51% of overall referrals. Overall, the number of patients being referred with an IOTN dental health component grade of 5 increased from 27% to 55%. Conclusion The increase in referrals from specialist practitioners may be partly due to the changes brought to the commissioning of orthodontic services for specialist practitioners. Overall, the number of cases being referred with IOTN grades 4 and 5 remains high at St George's Hospital, indicating that appropriate referrals are being made.

Objective: The purpose of this study was to determine perceived and normative orthodontic treatment need of senior year dental students using the Index of Orthodontic Treatment Need (IOTN) and Dental Aesthetic Index (DAI). Materials and Methods: Ninety-nine senior year students of the Faculty of Dentistry, Obafemi Awolowo University Ile-Ife, Nigeria, participated. Normative assessment of occlusal characteristics was car¬ried out using IOTN and DAI while the Aesthetic Component (AC) scale of IOTN was used by the students to assess perceived need. Results: With the AC scale of IOTN, 6.1% of the students expressed “borderline need” and 2% “great need” for treatment, while normative need was 41.4% for “borderline need” and 11.1% for “great need”. The Dental Health Component found 37.4% and 24.2% in these categories, respectively. The DAI gave 26.3%, 13.1% and 15.1% in the elective treatment, highly desirable treatment and mandatory treatment categories respectively. No gender-dependent differences were found. Moderate correlation was observed between perceived and normative need (r=0.643), which was significant (p<0.001). Conclusions: Over half of the dental students had orthodontic treatment need with both indices. Normative and perceived treatment need differed significantly. The perception of treatment need is not only influenced by knowledge and severity of malocclusion, as psychosocial factors acting on individuals may be involved.

Introduction: Malocclusion has an impact on the quality of life, thus becoming the motivation for orthodontic treatment. Subjective and objective needs for orthodontic treatment vary, where subjective needs are sometimes higher or maybe lower than objective needs, vice versa. The Index of Orthodontic Treatment Need (IOTN) is an index used to see the level of treatment needs. This study was aimed to analyse the correlation of orthodontic treatment motivation and the level of treatment needs based on the index of orthodontic treatment need (IOTN) of orthodontic patients. Methods: The research was correlation analytical. The motivation for orthodontic treatment was assessed using a questionnaire consisted of aspects of oral health motivation, oral function, aesthetics, psychosocial, and influence from others. The level of orthodontic treatment needs was assessed using the IOTN dental health component. Results: It was found that the patients’ motivation related to aesthetics was high. The motivation to get orthodontic treatment due to oral health, oral function, and psychosocial conditions was moderate, while related to the influence of others was low. The level of need for grade 4 treatment shows the largest percentage (48.57%). Gamma correlation analysis between motivation variables related to the oral and psychosocial function with the level of treatment needs showed a significantly positive correlation with the p-values of 0.003 and 0.022, categorized as weak correlation. Conclusion: There is a weak correlation of orthodontic treatment motivation and the level of treatment needs based on the index of orthodontic treatment need (IOTN) of orthodontic patients.

ABSTRACT Objective: To evaluate the prevalence and severity of malocclusion in children suffering from β-thalassemia and to assess orthodontic treatment need using Grainger’s Treatment Priority Index (TPI) and index of orthodontic treatment need (IOTN)-dental health component (DHC). Methods: A cross-sectional study was conducted on 200 transfusion-dependent children diagnosed with homozygous β-thalassemia and 200 healthy school children aged 11-17 years. The TPI and IOTN-DHC data was recorded for both groups. Total TPI score for each subject was calculated and graded according to malocclusion severity estimate (MSE). Independent sample t-test was used to compare mean TPI scores, overjet and overbite between thalassemic and healthy children. Chi-square test was used to compare the frequency of IOTN-DHC grades, Angle’s classification, and MSE grades between thalassemic and healthy children. Results: The most prevalent malocclusion was Class I in normal children (67.5%) and Class II in thalassemic children (59%). The mean overjet and overbite were significantly (p<0.001) greater in thalassemic children than in healthy children. Severe tooth displacements were 3.5 times greater in thalassemic children, compared to controls. A greater proportion of thalassemic children were in IOTN grades 3 and 4, compared to the controls (p<0.001). MSE grades 4 and 5 were significantly (p<0.001) more prevalent in thalassemic children, compared to the controls. Conclusion: There is a high prevalence of Angle’s Class II malocclusion in thalassemic children. Majority of these children are categorized in higher grades of IOTN-DHC and TPI-MSE, showing a great severity of malocclusion and high orthodontic treatment needs.

SUMMARY Introduction Need for orthodontic treatment is determined by the severity of specific malocclusion. Orthodontic indices are used to objectively present treatment needs. The most commonly used is the Index of Orthodontic Treatment Need (IOTN). The aim of this study was to determine the need for orthodontic therapy in 11 to 13 years old schoolchildren in Republika Srpska. Material and Methods 1377 patients, 11 to 13 years old, were included in this study. The examinations were performed in elementary schools, using daylight, flat mirror and two-dimensional orthodontic caliper. Patients were ranked into 5 grades according to the Dental Health Component (DHC) and graded on a scale 1 to 10 for the Aesthetic Component (AC) of the IOTN index. Results According to the Dental Health Component (DHC), 79.23% of patients needed orthodontic treatment. Little and borderline orthodontic need was present in 27.74% and 24.83% children, respectively, while severe need was present in 19.98% and 6.68% respectively. 20.77% of subjects did not need orthodontic treatment. In regards to the Aesthetic Component (AC) (face appearance related to orthodontic need) little or no treatment was needed in 91.42% of subjects while 6.42% were borderline and 2.16% of subjects had severe relation between orthodontic need and facial appearance. Conclusion Due to the wide presence of orthodontic irregularities in schoolchildren 11-13 years old in Republika Srpska, it is important to introduce orthodontic indices in clinical practice in order to determine orthodontic treatment needs.

The benefits of early orthodontic treatment are continuously discussed, but studies are few. We examined whether definite need for orthodontic treatment could be eliminated in public health care by systematically focusing on early intervention. One age cohort living in a rural Finnish municipality (N = 85) was regularly followed from ages 8 to 15 years, and persons with malocclusions were treated according to a pre-planned protocol. Treatment need was assessed according to the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need, and treatment outcome by the Peer Assessment Rating Index (PAR). Fifty-two percent of the cohort received treatment, and definite treatment need decreased from 33% to 9%. In the treated group, the mean PAR score reduction was 63%, and 51% showed more than 70% improvement. The results suggest that an early treatment strategy may considerably reduce the need for orthodontic treatment in public health care with limited specialist resources.
