Table 1.

Frequency of diagnostic response regarding extraction, monitoring or other alternatives for lower third molars given by orthodontists (n = 28) and oral/maxillofacial surgeons (OMFSs) (n = 28). Frequency distribution was evaluated by chi-square (χ²) and agreement between evaluators by Kappa test

	Orthodontists	OMFSs	Kappa (p value)
Extraction	360 (37.8 %)	472 (49.6 %)	0.76 (<0.0001)
Monitoring	586 (61.6 %)	478 (50.2 %)
Others	6 (0.6 %)	2 (0.2 %)
Total	952 (100 %)	952 (100 %)
Ortho × OMFSs (x 2)	25.56 (p < 0.0001), power 99 %
