ORTHODONTIC TREATMENT NEEDS OF CHILDREN: COMPARISON OF THREE INDEX-Çocuklarda Ortodontik Tedavi ihtiyacı: Üç indeksin Karşılaştırılması

ABSTRACT Purpose: An orthodontic treatment need index is a form of occlusal index devised initially to prioritize the need for treatment and to categorize the malocclusion and identify patients based upon treatment need. The aim of this study was to evaluate orthodontic treatment needs of children using IOTN (Index of Orthodontic Treatment Need), DAI (the Dental Aesthetic Index) and ICON (Index of Complexity, Outcome and Need) and the relationship among the three index. Material and Methods: After ethical approval and informed consent were obtained; 100 children aged 10-12 years were examined for malocclusion, overjet, overbite, open bite and crossbite. The study models of subjects were taken and the DAI, the Dental Health Component (DHC) and the Aesthetic Component (AC) of IOTN and ICON were compared. Statistical analysis was performed by using NCSS 2007 software and regression analysis was performed between the results. Results: The mean average scores of DAI, IOTN-DHC, IOTN-AC and ICON indices were 25.44±8.05, 2.46±0.98, 4.17±2.53 and 38.67±21.08, respectively. Statistically significant differences were found between DAI, IOTN-DHC, IOTN-AC and ICON scores (p<0.01). Conclusion: DAI, IOTN and ICON were found to be significantly correlated with each other regarding the prevalence of malocclusion and orthodontic treatment need. Keywords: IOTN, DAI, ICON, Orthodontic treatment need, orthodontic indexes OZ Amac: Ortodontik tedavi ihtiyaci indeksleri, tedavi ihtiyacinin onceliginin belirlenmesi ve tedavi ihtiyacina bagli olarak hastalarin ve malokluzyonlarin kategorize edilebilmesi icin tasarlanan okluzal indeks formudur. Bu arastirmanin amaci, cocuklarda ortodontik tedavi ihtiyacinin IOTN (Index of Orthodontic Treatment Need), DAI (the Dental Aesthetic Index) ve ICON (Index of Complexity, Outcome and Need) indeksleri kullanilarak degerlendirilmesi ve bu uc indeks arasindaki iliskinin belirlenmesidir. Gerec ve Yontem: Etik kurul onayi ve bilgilendirilmis onam formu alindiktan sonra, yaslari 10-12 arasinda degisen 100 cocuk malokluzyon, overjet, overbite, openbite ve crossbite acisindan klinik olarak muayene edilmistir. Hastalardan alt-ust cene alci modeler elde edilerek DAI, IOTN-AC (Aesthetic Component), IOTN-DHC (Dental Health Component) ve ICON indeksleri kullanilarak olcumler yapilmis ve bu olcumler karsilastirilmistir. Istatistiksel analizler, NCSS 2007 software programi ve regresyon analizi yontemi kullanilarak gerceklestirilmistir. Bulgular: Ortalama indeks skorlari DAI, IOTN-DHC, IOTN-AC ve ICON i cin sirasiyla 25.44±8.05, 2.46±0.98, 4.17±2.53 ve 38.67±21.08 olarak bulunmustur. DAI, IOTN-DHC, IOTN-AC ve ICON skorlari arasinda istatistiksel olarak anlamli farklilik elde edilmistir (p<0.01). Sonuc: Ortodontik tedavi ihtiyacinin ve malokluzyonun belirlenmesinde, DAI, IOTN ve ICON arasinda anlamli bir korelasyon bulunmu stur.
