Background and Aim: Assessment of skeletal maturity is an integral part of interceptive diagnosis and treatment planning. The present method of skeletal maturity assessment like handwrist or cervical vertebrae radiographies are expensive, require elaborate equipment and account for high radiation exposure, especially for growing children. This study tried to consider the value of the 2nd primary molar in growth stage.
Material and Method: 40 samples aged 8-13 were tested by their panoramic and handwrist radiographs.
Result and Conclusion: there was a coincidence between presence calcified sesamoid and 2nd primary molar as the last tooth. The result showed that it could be a reliable index to predict the growth stage in 1st visit without radiography. (IJO 2006; 1: 58 - 60)

Purpose: The long-term outcome and clinical results of gaparthro plasty used for the treatment of condylar ankylosis of the mandible in children with application of postoperative activator appliances and costochondral rib graft are evaluated and compared.
Materials and Methods: A nonrandomized, retrospective clinical study of 10 cases of condylar ankylosis (18 Joints) of the mandible surgically treated during a 12 year period from 1990 to 2002 was performed. Four patients were treated by condylectomy and interpositional Flap and Six patients were treated by condylectomy and Immediate costachondral rib grafts.
The First group underwent long-term postoperative therapy using removable activator appliances. Casts, radiographs, photographs, computed tomography (CT) Scans, were Used post surgically to evaluate rib graft, condylar growth and function, occlusion, and Facial and condylar symmetry.
Results: Symmetry, arch coordination, correction of occlusal canting, mandibular deviation, facial growth , and prevention of reandkylosis were obtained and better controlled in those cases that cnderwent long-tern orthodontic activator therapy post operatively and were followed closely.
Conclusions: Children with long-standing condylar ankylosis of the mandible and its resultant facial asymmetry and occlusal canting (Secondry to a non functional joint and Maxillary compensation) treated with condylectomy and interpositional flap treated more favorably when activators were used postsurgically. The patients that failed to comply with or continue activator therapy postsurgically developed complications relating to mandibular deviation , occlusal dysharmony, asymmetry and rankylosis of the temporo mandibular joint (TMJ).
