Objective. The aim of this study was to evaluate the need for orthodontic treatment among 12-year-old school children and 18-year-olds from Da Nang, Vietnam.Basic Research Design. A random representative sample of 200 12-year-old children from primary schools in Da Nang city was gathered. In addition, 200 18-year-old students were randomly selected from among the 4000 students studying at Da Nang University of Medical Technology and Pharmacy, Vietnam. All the subjects were evaluated according to Angle’s molar relationship, the presence of malocclusion, and the components of the Index of Orthodontic Treatment Need (Dental Health Component, DHC, and Aesthetic Component, AC).Results. The DHC of index of orthodontic treatment need (IOTN) for 12-year-olds was in 60% of casesno or little, in 21% of casesmoderate, and in 19% of casesdefinitive, while the prevalence of moderate and definitive need for treatment among the 18-year-olds was 24% and 30.5%, respectively. The prevalence of class III malocclusion, contact point displacement, and crossbite was higher in 18-year-olds than among the 12-year-olds, while the prevalence of increased overjet and increased overbite had decreased in 18-year-olds compared to the group of 12-year-olds.Conclusions. There is a strong need for orthodontic treatment in Vietnam’s population. The need for orthodontic treatment was determined by contact point displacement, crossbite, increased overjet, and increased overbite.

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.

Objectives: To calculate the agreement between the Dental Aesthetic Index (DAI) and the Index of Complexity, Outcome and Need (ICON) in assessing orthodontic treatment need and to determine correlations between the Peer Assessment Rating (PAR) and DAI and ICON scores according to Angle classification among patients referred for orthodontic evaluation. Study Design: This study included 457 randomly selected patients between 9 to17 years of age. Patients were divided into four groups according to Angle classification [Class I (n=154), Class II division 1(Class II/1) (n=155), Class II division 2(Class II/2) (n=52) and Class III (n=96)]. Relationships between PAR scores and ICON and DAI scores were evaluated with the Spearman correlation test. Unweighted kappa statistics were used to analyse agreement between the ICON and DAI on the need for treatment, according to Angle classification. Results: Class I malocclusions scored significantly lower than other Angle classifications in all indices. Both the ICON and DAI showed significant positive correlations with the PAR in the general study population. For Class II/2 patients, no correlation was found between PAR and DAI scores. There was significant agreement between the ICON and DAI on treatment need among Class I, Class II/1 and Class II/2 patients however, no agreement was found for Class III malocclusions. Conclusions: The ICON, DAI and PAR produce similar results and can be used interchangeably for the general orthodontic patient population. However, based on Angle classification, prominent differences exist in scoring certain occlusal features.

Abstract: Malocclusion is a form of occlusal disorders caused by irregular teeth growthas well as sizes and position of teeth. Malocclusion could create some disturbances in both physical and mental health of a person including problems in oral function, mastication, highly risk of trauma, periodontal diseases, and caries. Esthetically, malocclusion could affect a person’s appearances and psychological development especially in adolescent. Orthodontic treatment is performed to fix the malocclusion that could affect one’s oral health. The needs of orthodontic treatment itself can be leveled by using Index of Orthodontic Treatment Need (IOTN). This study was aimed to obtain the needs of orthodontic treatment based on IOTN among students aged 12-13 years old at SMPN 1 Wori. This was an observational descriptive study with a cross sectional design. There were 30 respondents obtained by using purposive sampling technique. The need of treatment was leveled by using IOTN consisted of two components: aesthetic component (AC) and dental health component (DHC). The needs of orthodontic treatment measured with AC, 27 person (90%) were as follows: no need or little need for treatment in 27 students (90%); borderline need in 2 students (6.7%); and treatment required in 1 student (3.3%). The needs of orthodontic treatment based on DHC were as follows: no need or little need for treatment in 18 students (60%); borderline need in 8 students (26.7%); and treatment required in 4 students (13.3%).Keywords: malocclusion, needs of orthodontic treatment, IOTN. Abstrak: Maloklusi merupakan penyimpangan oklusi akibat tidak teraturnya pertumbuhan, posisi, serta ukuran gigi. Maloklusi dapat menyebabkan gangguan kesehatan fisik dan psikis, antara lain dapat mengganggu fungsi oral, mastikasi, berisiko tinggi terhadap trauma, penyakit periodontal, dan karies. Maloklusi secara estetis juga dapat memengaruhi penampilan wajah seseorang dan perkembangan psikologis terutama pada remaja. Perawatan ortodonsi ditujukan untuk memperbaiki maloklusi yang dapat memengaruhi kesehatan gigi dan rongga mulut. Perawatan ortodonsi yang tepat dapat dilihat dari tingkat kebutuhan perawatan ortodonsi yang diukur dengan Index of Orthodontic Treatment Need (IOTN). Penelitian ini bertujuan untuk mengetahui kebutuhan perawatan ortodonsi berdasarkan IOTN pada siswa berusia 12 - 13 tahun di SMP N 1 Wori. Jenis penelitian ialah deskriptif observasional dengan desain potong lintang. Subjek penelitian berjumlah 30 siswa diperoleh dengan teknik purposive sampling. Kebutuhan perawatan ortodonsi menggunakan Index of Orthodontic Treatment Need (IOTN) dengan dua komponen, yaitu Aesthetic Component (AC) dan Dental Health Component (DHC). Kebutuhan perawatan ortodonsi berdasarkan AC yaitu: 27 orang (90%) tidak atau butuh perawatan ringan; 2 orang (6,7%) perawatan borderline; dan 1 orang (3,3%) sangat butuh perawatan. Kebutuhan perawatan ortodonsi berdasarkan DHC yaitu: 18 orang (60%) tidak atau butuh perawatan ringan; 8 orang (26,7%) perawatan borderline, dan 4 orang (13,3%) sangat butuh perawatan. Kata kunci: maloklusi, kebutuhan perawatan, IOTN

Objective: To analyze the prevalence of malocclusion and occlusal characteristics in referred Nepalese orthodontic patients with respect to age, gender, Angle’s classification. Materials & Method: Study models of 464 orthodontic patients (165 male and 299 female) of the age ranging from 11 to 30 years were studied to evaluate the prevalence of malocclusion using Angle’s classification and occlusal characteristics of overjet, overbite, open bite, cross bite, displacement, and hypodontia according to the method of Dental Health Component of Index of Orthodontic Treatment Need. The association between DHC grades and Angle’s classification and gender were assessed using chi-square test (p < 0.01). Result: The malocclusion status among the Nepalese seeking orthodontic treatment was 54.7% Class I, 36.9% Class II, and 8.4% Class III. The occurrence of occlusal discrepancies were overjet in 43.8%, increased overbite in 20.7%, open bite in 8.2%, cross bite in 23.3%, displacement in 65.7% and hypodontia in 11.3%. Conclusion: 16.2 % required no/little treatment need, 20.4% required borderline treatment need, and 63.4 % required great/severe treatment need according to DHC scale. There was statistically significant association between DHC grades and distribution of malocclusion and gender of the Nepalese subjects.

Background. Widespread use of the IOTN along with detailed study of occlusal traits is suitable for planning community dental health resources. Objectives. The aim of current study was to assess the need for orthodontic treatment among school children of Tehran by means of the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and also to evaluate the occlusal traits of the subjects. Methods. 684 (343 boys and 341 girls) school children, 15 to 17 years of age, were selected at random from 12 schools to represent the four main areas of Tehran. The final sample who met the inclusion criteria comprised 643 subjects (322 males and 321 females). Malocclusion was determined with the Index of Orthodontic Treatment Need. The IOTN grades were statistically compared in the two genders using chi-square test. Results. Orthodontic treatment need, using the DHC, was found in only 9.0 per cent of the children. The prevalence of Angle Class I malocclusion in this study was higher than other malocclusions (65.2 per cent), followed by crowding in 62.7 per cent of the subjects. Conclusion. Orthodontic treatment need for Tehran high school students was relatively lower than that reported in most recent studies in Europe.

The purpose of this research was to assess the orthodontic status and orthodontic treatment needs of 12- and 15-year-old schoolchildren in Greece, in relation to sociodemographic factors and parental education level. A total of 1102 12-year-old children and 1131 15-year-old adolescents across Greece were assessed using the Modified Dental Health component (DHC) of the Index of Orthodontic Treatment Need (IOTN). An amount of 38.7% of 12-year-olds and 33.7% of 15-year-olds were in definite need of orthodontic treatment. The most common etiologic factors were tooth eruption and position anomalies. A higher rate of orthodontic treatment need was recorded among subjects with lower parental education level. Class I malocclusion was found in 50.9%, Class II in 38.4% and Class III in 10.8% of the total sample. A higher incidence of dental trauma was found in the 12-year-olds presenting with a Class II molar relationship and >3 mm overjet. The need for orthodontic treatment in Greece was higher, in comparison to other European countries, with one out of two children presenting a severe overjet associated with a high incidence of dental trauma. One out of three adolescents were still judged as having a need for orthodontic treatment by the age of 15.
