Purpose
This study primarily aimed to assess the accuracy of radiographic dental calcification parameters for the identification of specific craniofacial growth stages.
Methods
Permanent mandibular canines, premolars, and second molars of 288 patients, from 6 to 15 years old, were analysed on randomly selected panoramic radiographs, and categorised according to two calcification methods. Reproducibility analyses and data derived from panoramic records were correlated with the gold-standard method, as evaluated from lateral cephalometric teleradiographs. Accuracy tests were finally calculated, considering several cutoff points.
Results
Dental calcification methods showed “strong” to “almost perfect” intra- and inter-examiner reproducibility. Significant, although weak correlations were observed for all parameters. Canine and first premolar calcification stage 8 and second premolar and second molar stage 7 showed higher sensitivity rates for identifying the pubertal growth spurt period, as well as the stage F for these teeth. Canine and first premolar stages 10 and H obtained higher specificity rates for identifying the absence of post-pubertal period.
Conclusions
The dental calcification parameters showed adequate reproducibility, in addition to significant correlations with cervical vertebrae stages. Radiographic dental calcification parameters used for the mandibular first premolar obtained high accuracy rates and were recommended for identifying specific craniofacial growth periods.
