Evaluation of treatment changes produced by different orthodontic treatment modalities using Peer Assessment Rating (PAR) index

Background: The evaluation of orthodontic treatment outcomes using an objective method is important in order to maintain high treatment quality and final healthcare of patients. It allows professionals and university students to raise the level of the therapy. The aim of this study was to assess the orthodontic treatment outcomes in an Italian postgraduate School of Orthodontics using Peer Assessment Rating (PAR) Index. Methods: A sample of 50 patients treated in a postgraduate program was randomly selected. PAR index was used to assess pre-treatment and post-treatment study casts by two different examiners. The influence of different variables such as gender, treatment method, and need for extraction was statistically analyzed. Results: The average numerical reduction of PAR between the beginning and the end of the treatment was 18.74 (CI 95% 16.53–20.95), while the percentage reduction was 94.8% (CI 95% 91.91–97.68). All cases improved: 8% of patients resulted in the improved category, while 92% of them were in the greatly improved group. Conclusions: According to PAR index, the results showed that patients received a high-standard therapy. None of the factors studied influenced significantly the treatment outcomes.

Abstract Objective: To evaluate treatment changes and quality of finishing occlusion in Class I patients treated with four premolar extractions. Material and Methods: Dental casts of 94 subjects (50 males and 44 females) were evaluated. Mean pretreatment age was 13.46 years, and mean treatment time was 2.09 years. The peer assessment rating (PAR) index was obtained from pretreatment and posttreatment dental casts. Results: The mean pretreatment PAR index of 29.46 was reduced to 6.32 at posttreatment stage, achieving a reduction of 78.54% with treatment. There was correlation between the initial PAR and correction during treatment, that is, the more severe the malocclusion the greater the treatment changes. Conclusion: The cases evaluated showed a high-standard orthodontic finishing.

Abstract: The aim of orthodontic treatment is to reach the best functional and esthetic occlusion. Because there are differences of opinions among clinicians about orthodontic treatment outcomes, the evaluation of orthodontic treatment outcomes will be more accurate and objective if we apply specific criteria that can be measured. Recently, only PAR Index (Peer Assessment Rating Index) can be accepted universally as reliable and valid in order to evaluate orthodontic treatment outcomes. The aim of this study was to evaluate the outcomes of orthodontic treatment using the Begg Appliance by Peer Assessment Rating Index. The object of this study consisted of 248 pairs of dental casts that contained 124 dental casts before treatment and 124 dental casts after treatment, which information were obtained from the patient case archive of those treated with the Begg Appliance at the Orthodontic Clinical Faculty of Dentistry, Gadjah Mada University 1996-2004. Dental casts that fulfilled the requirements were measured using the PAR Ruler and then assessed using the PAR Index. Scoring was applied to each component. The score of each component was weighted, and then the difference of score was calculated before and after treatment. That represents the degree of improvement as a result of orthodontic treatment. The result revealed that PAR Index can be used to evaluate orthodontic treatment outcomes using the Begg Appliance. Keyword: PAR Index, orthodontic treatment outcomes. Abstrak: Tujuan perawatan ortodontik adalah mendapatkan kemungkinan oklusi terbaik secara fungsional maupun secara estetik. Terdapat beberapa hal yang menyebabkan terjadinya perbedaan antar klinisi dalam evaluasi hasil perawatan ortodontik. Oleh karena itu evaluasi ini akan lebih akurat dan objektif jika menggunakan kriteria tertentu yang dapat diukur. Dewasa ini satu-satunya indeks untuk menilai hasil perawatan ortodontik yang telah diterima secara universal, reliabel dan valid adalah PAR Index (Peer Assessment Rating Index). Tujuan penelitian adalah untuk mengukur dan menilai secara objektif penggunaan Peer Assesment Rating Index pada evaluasi hasil perawatan ortodontik dengan Teknik Begg. Objek penelitian terdiri dari 248 pasang model studi rahang atas dan bawah, yaitu 124 pasang model studi sebelum perawatan dan 124 pasang model studi sesudah perawatan. Objek penelitian diperoleh dari arsip kasus pasien yang dirawat dengan Alat Ortodontik Cekat Teknik Begg di Klinik Ortodonsia Fakultas Kedokteran Gigi Universitas Gadjah Mada Tahun 1996-2004. Model studi yang memenuhi persyaratan tersebut diukur menggunakan PAR Ruler dan kemudian dinilai menggunakan PAR Index. Dilakukan penghitungan skor untuk tiap komponen, dilakukan penghitungan dengan pembobotan, kemudian dihitung selisih skor sebelum dan sesudah perawatan, yang menggambarkan derajat perbaikan dan keberhasilan perawatan ortodontik. Hasil penelitian menunjukkan bahwa PAR Index dapat digunakan untuk evaluasi hasil perawatan ortodontik dengan Teknik Begg. Kata kunci: PAR Index, hasil perawatan ortodontik.
