Orthodontic treatment needs in the western region of Saudi Arabia: a research report

BACKGROUND: Evaluation of self perceived and actual need for orthodontic treatment helps in planning orthodontic services and estimating the required resources and man power. In the present study, the perceptive need as evaluated by patients and the actual need to orthodontic treatment, as assessed by orthodontists, were evaluated at two types of dental practices in the city of Jeddah using the Index of Orthodontic Treatment Need (IOTN). METHODS: A consecutive sample of 743 adults seeking orthodontic treatment at two different types of dental practices in Jeddah; King Abdulaziz University, Faculty of Dentistry (KAAU) (Free treatment) and two private dental polyclinics (PDP) (Paid treatment), was examined for orthodontic treatment need using the dental health component (DHC) of the IOTN. The self-perceived need for orthodontic treatment was also determined using the aesthetic component (AC) of the IOTN. The IOTN score and the incidence of each variable were calculated statistically. AC and DHC categories were compared using the Chi-Square and a correlation between them was assessed using Spearman's correlation test. AC and DHC were also compared between the two types of dental practices using the Chi-Square. RESULTS: The results revealed that among the 743 patients studied, 60.6% expressed no or slight need for treatment, 23.3% expressed moderate to borderline need and only16.1% thought they needed orthodontic treatment. Comparing these estimates to professional judgments, only 15.2% conformed to little or no need for treatment, 13.2% were assessed as in borderline need and 71.6% were assessed as in need for treatment (p < 0.001). Spearman's correlation test proved no correlation (r = -.045) between the two components. Comparing the AC and the DHC between the KAAU group and PDP group showed significant differences between the two groups (p < 0.001). CONCLUSION: Patient's perception to orthodontic treatment does not always correlate with professional assessment. The IOTN is a valid screening tool that should be used in orthodontic clinics for better services especially, in health centers that provide free treatment

Development of a treatment outcome standard as a result of a clinical audit of the outcome of fixed appliance therapy undertaken by hospital-based consultant orthodontists in the UK.

Bristol's much-publicised cardiac surgery problems and subsequent enquiry(1) have drawn attention to the need for audit of treatment outcomes throughout all hospital specialties. Patient anxiety, government policy and the desire of the professions to re-establish public confidence, have further encouraged changes to the system. For medical and dental specialties, such challenges have already been taken up by the Royal Colleges with the establishment of clinical effectiveness committees. Hospitals have modified their procedures and, for consultants, yearly appraisal is already a reality. The Orthodontic Clinical Effectiveness Working Party of the Royal College of Surgeons of England (now the Clinical Effectiveness Committee of the British Orthodontic Society) set up this audit to measure the outcome of fixed appliance treatment and to establish a benchmark for the standard of treatment to be expected from a consultant orthodontist. This paper describes how the audit was carried out, presents the findings and goes on to discuss some of the wider issues involved in audit, clinical governance and appraisal. The Consultant Orthodontists Group of the British Orthodontic Society funded this audit and the results and data set of dental casts remain their property
