الملخص EN

Background : Dental development provides the orthodontist an invaluable information for providing proper timing of certain preventive & interceptive orthodontic measures.

The aim of this study was to find out the normative values of crown & root lengths & developmental stage of maxillary permanent canine and first & second molars of Iraqi primary school children aged 8, 10 & 12 years of age using OPG 5.

Materials & Methods: Crown length & root development was studied in 60 Iraqi primary school children aged 8 to 12 years old using Orthopantomograph 5.

Results : Crown length & root length was seen greater in females than in males and a gradual increase in root length was observed as we pass from age of 8 years toward 12 years of age indicating that root calcification was evident and pass faster in females than in males.

Conclusion : This study provide information about the normal development of maxillary dentition represented by canine, first & second molars.
