Table 3 Accuracy of the diagnostic answers given, according to specialisation: residents in oral surgery versus residents in orthodontics

From: Do we need CBCTs for sufficient diagnostics?-dentist-related factors

Question pertaining to OS (%) ORTH (%) p value Odds ratio (95% CI)
Contact to nerve 96 87 0.002* 3.8 (1.4–12.0)
Displacement of tooth 92 87 0.089 1.9 (0.9–4.1)
Number of roots 95 95 1.000
Contact to adjacent teeth 74 71 0.626 1.1 (0.7–1.9)
Pericoronar cyst 77 72 0.323 1.3 (0.8–2.2)
Maturation of root 89 80 0.029* 2.0 (1.1–3.7)
Resorption (bone or tooth) 76 65 0.040* 1.7 (1.0–2.8)
Ankylosis 83 89 0.176 0.6 (0.3–1.3)
Preservation 79 80 0.793 0.9 (0.5–1.6)
  1. Percentage of correct answers given by residents in oral surgery (OS) and residents in orthodontics (ORTH). To assess the differences between the specialisations, p value of Fisher’s exact test is given together with odds ratio (OR), including 95% confidence intervals (CI). OR refers to OS with ORTH as reference. *p < 0.05
