Inter-rater reliability of stress signatures in exfoliated primary dentition - Improving scientific rigor and reproducibility in histological data collection
Fig 5
Example of a section used in this study demonstrating the difference between pair ratings.
(A) Overview of a histological tooth section with the enamel in brown and dentine in dark black. The occlusal surface is facing down, with the dentine horn being exposed due to wear. The cervical enamel area shows clear ALs (red arrow). (B) Magnification of the indicated area with ALs from (A). (C, D, E) Ratings of pairs 1, 2, and 3, where each pair of two raters jointly marked the buccal enamel for AL presence and intensity. All pairs agreed on the NNL (red) and the presence of 1 MAL (off-white) as the first AL following the NNL. All pairs also marked the presence of multiple HALs in the cervical enamel (green) but had differences in how many HALs should be included in data collection.
