ABSTRACT Objective:  To validate our hypothesis that there would be significant differences in treatment outcomes, including cephalometric values, degree of root resorption, occlusal indices, and functional aspect, between cases treated with labial and lingual appliances. Materials and Methods:  Twenty-four consecutively treated Class II cases with extractions and lingual appliance were compared with 25 matched cases treated with extraction and labial appliance. Orthodontic treatment outcomes were evaluated by cephalometric analysis, peer assessment rating, and an objective grading system (OGS). Additionally, functional analysis was also performed in both groups after orthodontic treatment. Statistical comparison was performed using the Wilcoxon signed rank test within the groups, and the Mann-Whitney U-test was used to compare between the labial and lingual groups. Results:  The only significant difference between the groups was that the interincisal angle was larger in the lingual group than in the labial group. OGS evaluation showed that control over root angulation was significantly worse in the lingual group than in the labial group. There was no significant difference between groups in the amount of root resorption or in functional evaluation. Conclusions:  Generally, lingual appliances offer comparable treatment results to those obtained with labial appliances. However, care should be taken with lingual appliances because they are more prone to produce uprighted incisors and root angulation.

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 Materials and Methods A sample of 62 patients were selected prior to the orthodontic treatment from a population that attended the International Islamic University Malaysia Specialist Orthodontic Clinic. Based on the lateral cephalometric analysis, the subjects were grouped into Class I, Class II, and Class III facial skeletal patterns, according to Eastman and Wits appraisal. Subsequently, unstimulated saliva samples were taken and purified to undergo leptin enzyme-linked immunosorbent assay analysis to determine the levels of leptin hormone. Statistical analysis using the Kruskal–Wallis test was used to analyze the data obtained. Results The results showed that there was a significant difference between the levels of leptin hormone between Class I and Class II skeletal patterns and between Class I and Class III facial skeletal patterns. No statistical difference was noted between the levels of leptin of Class II and Class III facial skeletal patterns. Conclusion Salivary leptin hormone levels are higher in patients with Class II and Class III facial skeletal patterns compared with Class I.

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.

The Stability

The purpose of this study was to examine the stability of orthodontic treatment results in dentoskeletal class I malocclusion treated with and without extraction of four premolars and to compare the stability of treatment result between those groups. Occlusal relationship after treatment and six-month post retention were measured on dental cast using The Objective Grading System Index at Orthodontic Specialist Clinic, Faculty of Dentistry Universitas Padjadjaran. The analytic descriptive study was carried out on 30 samples that comprised 14 samples were treated without extraction of four premolars and 16 samples were treated with extraction of four premolars. ABO Measuring Gauge was used to measure seven variables: tooth alignment, the height of the marginal ridges, buccolingual inclination, occlusal relationships, occlusal contacts, overjet, and interproximal tooth contacts. The results were statistically analyzed with the Wilcoxon rank test to test the difference of The Objective Grading System Index between posttreatment and postretension. Mann-Whitney U test was applied to determine the difference between the group with the extraction of four premolars and the group without extraction of four premolars. The level of significance was set at 0.05. The results of this study showed these following variables: tooth alignment, occlusal contacts, and overjet were unstable at the group with the extraction of four premolars, while only tooth alignment was found to be unstable in the group without extraction of the four premolars. Mann-Whitney U test did not show statistically significant difference in stability comparison test between the groups.
