Assessment of skeletal maturity and dental development is a common clinical practice in many health professions. Aims of this investigation were: 1) to test the applicability of the Demirjian46 method for dental age assessment and Greulich and Pyle47 atlas method for assessment of skeletal maturity to the Saudi male children; 2) to study the relationship between dental development, skeletal maturity and chronological age in Saudi male children; and 3) to study the association between the dental maturity markers and the skeletal maturity stages in Saudi male children. Materials and Methods: The sample consisted of panoramic and hand-wrist radiographs of 148 Saudi male children between 9 and 15 years of age. Demirjian46 method was used to estimate the dental age through the assessment of different calcification stages of the left mandibular dentition. Skeletal age was determined using Greulich and Pyle47 atlas and skeletal maturity stage was established utilizing Björk’s21 skeletal maturity indicators. Results: Paired sample T-test revealed no significant difference between the mean dental, skeletal and chronological age. Tendency toward late skeletal maturation and early dental maturation was observed. Spearman rank order test showed high correlation between skeletal maturity markers and dental maturity markers of the 1st premolar (r=0.729) and 2nd molar (r=0.720). Conclusion: chronological age is a reasonable indicator of the dental and skeletal maturation in Saudi male children. The dental maturation stage of the left mandibular 1st premolar and 2nd molar can be used to predict the skeletal maturity stage in Saudi male children. The skeletal maturity rate of Saudi male children is analogous to previously reported rates in other groups with different ethnic backgrounds.
