Abstract
Background: Among different treatment modalities of skeletal malocclusion, growth modification is the interceptive procedure undertaken in a growing child. For the growth modification to be successful it is absolutely essential that it should be initiated at the right time. This study aimed to verify the possibility of clinical employment of the developmental stage of middle phalanx of the middle finger and that of mandibular second molar in the determination of maturity in both genders. Materials and method: The sample consists of 216 Iraqi subjects, 108 males and 108 females, for each subject two periapical radiographical films were used, one for mandibular left second molar and the other for the middle phalanx of the middle finger, to determine their developmental stage according to the method described by Demirjian et al (1973) for ossification of teeth, and Hagg and Taranger (1982) that later modified by adding E ¾ stage given by Leite et al (1987) to describe the relation of epiphysis to metaphysis in the middle phalanx of the middle finger. Results: A high significant correlations were found among chronological age, in years, calcification stages of mandibular left second molar , and developmental stages of middle finger (P<0.000), with a higher puberty stage in female than in male within the same dental calcification stage. Conclusion: The maturity stage of growing subject can be detected depending on calcification stage of mandibular 2nd molar using periapical radiograph.
