Reliability among dental hygienists (n = 32) using infrared transillumination images

Evaluation	Fair agreement, n (%)	Moderate agreement, n (%)	Substantial agreement, n (%)	Almost perfect agreement, n (%)
EVA 1	–	4 (12.5)	15 (46.9)	13 (40.6)
EVA 2	–	2 (6.2)	24 (75.0)	6 (18.8)
Drop-out after EVA 1, n = 16	–	4 (25.0)	6 (37.5)	6 (37.5)
EVA 1/EVA 2	4 (12.5)	9 (28.1)	10 (31.2)	9 (28.1)

Interexaminer and intraexaminer reliability is categorized by following the scale of the degree of agreement in the two evaluations (immediately after training and 1 month later) reported in table as EVA 1 and EVA 2.
