BACKGROUND: The knowledge of facial growth and development is fundamental to determine the optimal timing for different treatment procedures in the growing patient. AIM: To analyze the reproducibility of three methods in assessing individual skeletal maturity, and to evaluate any degree of concordance among them. DESIGN: In all, 100 growing subjects were enrolled to test three methods: the hand-wrist, cervical vertebral maturation (CVM), and medial phalanges of the third finger method (MP3). Four operators determined the skeletal maturity of the subjects to evaluate the reproducibility of each method. After 30 days the operators repeated the analysis to assess the repeatability of each method. Finally, one operator examined all subjects' radiographs to detect any concordance among the three methods. RESULTS: The weighted kappa values for inter-operator variability were 0.94, 0.91, and 0.90, for the WRI, CVM, and MP3 methods, respectively. The weighted kappa values for intra-operator variability were 0.92, 0.91, and 0.92, for the WRI, CVM, and MP3 methods, respectively. CONCLUSION: The three methods revealed a high degree of repeatability and reproducibility. Complete agreement among the three methods was observed in 70% of the analyzed samples. The CVM method has the advantage of not necessitating an additional radiograph. The MP3 method is a simple and practical alternative as it requires only a standard dental x-ray device.

Abstract

BACKGROUND: The knowledge of facial growth and development is fundamental to determine the optimal timing for different treatment procedures in the growing patient. AIM: To analyze the reproducibility of three methods in assessing individual skeletal maturity, and to evaluate any degree of concordance among them. DESIGN: In all, 100 growing subjects were enrolled to test three methods: the hand-wrist, cervical vertebral maturation (CVM), and medial phalanges of the third finger method (MP3). Four operators determined the skeletal maturity of the subjects to evaluate the reproducibility of each method. After 30 days the operators repeated the analysis to assess the repeatability of each method. Finally, one operator examined all subjects' radiographs to detect any concordance among the three methods. RESULTS: The weighted kappa values for inter-operator variability were 0.94, 0.91, and 0.90, for the WRI, CVM, and MP3 methods, respectively. The weighted kappa values for intra-operator variability were 0.92, 0.91, and 0.92, for the WRI, CVM, and MP3 methods, respectively. CONCLUSION: The three methods revealed a high degree of repeatability and reproducibility. Complete agreement among the three methods was observed in 70% of the analyzed samples. The CVM method has the advantage of not necessitating an additional radiograph. The MP3 method is a simple and practical alternative as it requires only a standard dental x-ray device.
