Case Basis

The subjective grading of cases at the Dental Practice Board of England and Wales was compared to the Peer Assessment Rating Index (PAR) and Index of Orthodontic Treatment Need (IOTN) in assessing 1505 cases sampled at the Board between Late 1990 and mid-1991. Whilst some criteria are common to both systems, case by case there is only limited agreement; sources of disagreement are evaluated. The indices are essentially epidemiological tools; whilst they have shortcomings in assessing individual cases, they are related to peer opinion, and show good reliability when used on samples of cases. They can be readily updated, as findings of research or future peer opinion may dictate. Use of PAR and IOTN at the Board, instead of subjective gradings, would require a departure from decisions on withholding payment on a case by case basis. If, however, they were used onsamples of practitioners' caseloads to assess reduction of malocclusion, and residual malocclusion and need for treatment, practitioners fees could be up- or down-graded periodically according to their overall performance, to encourage more to adopt higher standards. Allowances could be made, however, for ‘limited objective treatments’ and cases where poor co-operation had impaired the result.

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.

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.

Aim: To determine factors that may influence the outcome of orthodontic treatment undertaken in General Dental Services/Personal Dental Services in South East Wales. Design and setting: A retrospective study of a requested 20 consecutively treated cases (for the year 2014–2015) provided by 26 performers in South East Wales. Method: Performer and patient information was obtained by use of a questionnaire and FP17OW forms, respectively. A calibrated investigator recorded the Index of Orthodontic Treatment Need (IOTN), Peer Assessment Rating (PAR) and the Index of Complexity, Outcome and Need (ICON) on start- and end-study models for each case. Descriptive and regression analyses were undertaken to identify any predictive factors of a good treatment outcome. Results: Two respondents completed < 20 cases, so all of their cases were assessed. A total of 495 cases were assessed. The overall achieved mean end-PAR score of 5 is collectively a good occlusal outcome. Predictive factors of a good quality of occlusal outcome (end-PAR score being ⩽ 5) were: dual arch treatment; use of functional with fixed appliances; treatment undertaken in non-corporate practices; and treatment undertaken by registered specialists ( P < 0.001). Predictive factors for occlusal improvement (change in PAR score) were: IOTN aesthetic component (AC); IOTN dental health component (DHC) (1–3 or 4–5); and number of arches treated and malocclusion type ( P < 0.001). Conclusions: Dual arch fixed appliances undertaken by orthodontic specialists in non-corporate environments produced the highest quality orthodontic outcomes. Those who have the highest need for treatment according to IOTN DHC and AC benefit most in terms of improvement achieved in PAR score.

Background/Aim. Occlusal indices are quantitative diagnostic indicators of malocclusion severity, orthodontic treatment need, complexity and outcome. The aim of this study was to determine correlations and agreement among three occlusal indices: the Index of Orthodontic Treatment Need (IOTN), the Peer Assessment Rating Index (PAR) and the Index of Complexity, Outcome and Need (ICON) in evaluating orthodontic treatment need. Methods. A total eighty study models of patients referred to the Department of Orthodontics, School of Dentistry, Belgrade, were assessed in this retrospective study. Malocclusions of various types and severity in the permanent dentition were included. Results. The Aesthetic and the Dental Health Component of IOTN determined orthodontic treatment need in 25% and 51% of the patients, respectively. PAR determined orthodontic treatment need in 59% and ICON in 53% of patients. The Aesthetic Component of IOTN and ICON had the highest correlation (Spearman's correlation coefficient 0.95, p < 0.01). Correlations between indices were 0.44 to 0.61 with statistical significance (p < 0.01). The agreement between indices, calculated using Kappa statistics, was 0.22 to 0.63. Conclusion. The most critical in malocclusion assessment was PAR. The Aesthetic Component of IOTN and ICON correlated highly (p < 0.01). Correlations between other pairs of indices were moderate (p < 0.01). The Aesthetic Component of IOTN and ICON had substantial agreement, whereas agreement between other indices was fair or moderate. ICON could replace PAR and IOTN. Application of occlusal indices enables objective evaluation of orthodontic treatment need and easier determination of the treatment priorities.

The PAR (Peer Assessment Rating) Index was compared to the grading system currently in use for completed orthodontic cases at the Dental Practice Board of England and Wales. Forty completed cases were graded by the two systems, which were compared for their intra- and inter-examiner reliability, as well as for their agreement and disparity in judging outcomes of cases. The implications of the results on the monitoring of standards in the General Dental Services are discussed.

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.

Suitable Index

Surveys of the occlusion in population groups usually include in their objectives the academic assessment of occlusal features, the planning of resources for public health treatment programmes, the comparison of differing populations and the screening of groups for orthodontic treatment. The requirements for these purpose differ. While occlusal features are readily measured by any trained observer, the need for treatment is a largely subjective judgement and the difficulty and practicability of treatment are aspects which can only realistically be assessed by clinical orthodontists. The use of an occlusal index, while standardizing the measurement of the occlusion, still retains the subjectivity of the assessment of treatment need, though this subjectivity is also standardized. No occlusal index at present includes any measure of the difficulty or practicability of treatment. Reports of orthodontic surveys on UK populations in the past 30 years reflect the difficulties of making comparable assessments without standardized criteria, as well as secular changes in judgment of treatment need. If surveys are to be of value either in resource planning, screening or comparison of populations there seems to be a need to develop a suitable index which would use measurements rather than classifications as far as possible.

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.
