Abstract
OBJECTIVES: To investigated the diagnostic performance of circumpubertal eruption stages which identify skeletal maturity stages using the cervical vertebral maturation (CVM) method in a Saudi population. METHODS: This is a retrospective cross-sectional study. Lateral cephalograms, panoramic radiographs, and intraoral pictures of 600 orthodontic patients (284 boys, 316 girls) who met inclusion criteria were assessed. Records were retrieved between January 2016 and April 2018. The diagnostic performance of eruption stages for identifying skeletal maturity was tested with positive likelihood ratios (LHR+). RESULTS: Prevalence of each CVM stage in the eruption stages was reported. For every eruption stage, LHR+ was reported in order to identify every CVM stage. The majority of the LHR+ values were ≤3.5, with a significant value of ≥10 for the identification of the post-pubertal growth stage. The other eruptions stages did not strongly predict skeletal maturity. CONCLUSION: In treatment planning for cases that require identifying the growth peak, the use of eruption stages is not recommended as an indicator of skeletal maturity except for the early permanent dentition stage where strong diagnostic performance for identifying post-pubertal skeletal growth stage has been shown.
