هدف: هدف از اين پژوهش، ارزيابي ميزان نياز به درمان ارتودنسي در دانش آموزان 14 تا 18 ساله ي شهر شيراز با استفاده از نمايه ي IOTN بود.
مواد و روش: 1818 دانش آموز 14 تا 18 ساله با استفاده از روش خوشه اي تصادفي از نواحي چهار گانه ي آموزش و پرورش شيراز انتخاب گرديدند. از ارزيابي دنداني (DHC) و زيبايي (AC) نمايه ي IOTN براي ارزيابي نياز به درمان ارتودنسي استفاده شد. همچنين، پرسشنامه اي شامل مشخصات فردي هر دانش آموز تكميل گرديد. داده ها به وسيله ي آزمون تي و مجذور كا واكاوي شد.
يافته ها: 60 درصد دانش آموزان نيازي به درمان ارتودنسي نداشتند، 4/28 درصد آنها در مرحله ي بينابيني نياز به درمان قرار داشته و 7/11 درصد داراي مال اكلوژن با نياز قطعي به درمان بودند. ارتباط نزديكي هم ميان شدت مال اكلوژن و جنس يا شغل يا ميزان تحصيلات پدر
دانش آموزان يافت شد (05/0 > p ).

Abstract :
Statement of Problem: Iran has one of the highest numbers of young people in the world; therefore, epidemiologic studies of dento-skeletal malformations in adolescents and young adults are important from population health viewpoints.
Purpose: The purpose of the study was to assess the needs for orthodontic treatment according to Index of Orthodontic Treatment Needs (IOTN) in 14-18 year old students in the city of Shiraz
