Table 4 Positive likelihood ratios for the combined dental maturation stages for the diagnosis of growth phases

From: Diagnostic performance of combined canine and second molar maturity for identification of growth phase

Tooth and maturation stage Growth phase positive
Pre-pubertal Pubertal Post-pubertal
Combination of two stages    
 Canine G with second molar F 2.0 (1.0 to 4.1) 1.2 (0.6 to 2.6) 0.2 (0.1 to 0.8)
 Canine G with second molar G 0.7 (0.2 to 2.0) 2.6 (0.9 to 8.0) 0.6 (0.1 to 2.5)
 Canine H with second molar F 1.0 (0.4 to 2.6) 1.1 (0.4 to 3.4) 0.8 (0.3 to 2.6)
 Canine H with second molar G 0.3 (0.2 to 0.4) 2.3 (1.6 to 3.4) 1.8 (1.2 to 2.6)
Combination of three stages    
 Canine G with second molar F/G 1.5 (0.8 to 2.6) 1.5 (0.9 to 2.8) 0.3 (0.1 to 0.7)
 Canine H with second molar F/G 0.4 (0.2 to 0.5) 2.1 (1.5 to 2.9) 1.5 (1.1 to 2.2)
 Canine G/H with second molar F 1.4 (0.8 to 2.5) 1.5 (0.8 to 2.6) 0.3 (0.1 to 0.8)
 Canine G/H with second molar G 0.4 (0.2 to 0.5) 2.1 (1.5 to 3.0) 1.5 (1.0 to 2.2)
  1. Data are presented as mean (95% confidence interval). The cases for the canine stages up to stage F or the second molar stages up to stage E, and those for the second molar stages from stage H, which showed positive LHRs ≥10 for the diagnosis of the pre-pubertal and post-pubertal growth phases, respectively, are not shown.
