title: Inter- and intra-observer identification of landmarks used in the Delaire analysis.
abstract: The investigation of intra- and inter-observer tracing error of points S, N, ANS, A, B, Me, Go, and Ba (conventional cephalometric points) and some of the landmarks used in the Delaire analysis (FM, M, CT, Clp, and Br) shows that a high level of intra-observer repeatability was achieved for each landmark, and that no statistically significant differences occurred. Also there were no statistically significant differences on inter-observer comparison of averaged values for the replicate tracings of each observer. However, the gross error which may occur in an individual case may be of considerable clinical significance.
