Defects were created with spherical diamond burs (numbers 1013, 1016, 3017) in superior and/or posterior surfaces of twenty condyles. The condyles were scanned, and cross-sectional reconstructions were performed with nine different protocols, based on slice thickness (0.2, 0.6, 1.0 mm) and on the filters (original image, Sharpen Mild, S9) used. Two observers evaluated the defects, determining their presence and location. Statistical analysis was carried out using simple Kappa coefficient and McNemar's test to check inter- and intra-rater reliability. The chi-square test was used to compare the rater accuracy. Analysis of variance (Tukey's test) assessed the effect of the protocols used. Kappa values for inter- and intra-rater reliability demonstrate almost perfect agreement. The proportion of correct answers was significantly higher than that of errors for cavitary defects on both condyle surfaces (p < 0.01). Only in identifying the defects located on the posterior surface was it possible to observe the influence of the 1.0 mm protocol thickness and no filter, which showed a significantly lower value. Based on the results of the current study, the technique used was valid for identifying the existence of cavities in the condyle surface. However, the protocol of a 1.0 mm-thick slice and no filter proved to be the worst method for identifying the defects on the posterior surface.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-04-08T15:35:11Z No. of bitstreams: 1 1806-8324-bor-27-06-0503.pdf: 2290444 bytes, checksum: e465c92a6e3cc886a0b780507ccba090 (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2014-10-10T15:07:20Z (GMT) No. of bitstreams: 1 1806-8324-bor-27-06-0503.pdf: 2290444 bytes, checksum: e465c92a6e3cc886a0b780507ccba090 (MD5)Made available in DSpace on 2014-10-10T15:07:20Z (GMT).
