Abstract
Purpose : To study the intra- and interobserver agreement of multidetector row computed tomography (MDCT) in interpretation of degenerative changes of the mandibular condyle.
Materials & Methods : Five observers independently evaluated one hundred temporomandibular joint MDCT
images for signs of osteophytes, erosion, sclerosis and flattening. The intra- and interobserver agreements were
calculated by using Kappa statistics.
Results : The intraobserver agreement was substantial for erosion (k=0.75), flattening (k=0.74) and sclerosis
(k=0.72) and almost perfect for osteophytes (k=0.84). The interobserver agreement was fair for flattening
(k=0.39), moderate for erosion (k=0.58) and sclerosis (k=0.48) and substantial for osteophytes (k=0.75).
Conclusion : This study shows that we can expect good agreement for the presence of osteophytes, but not for
flattening in the interpretation of MDCT images of the condyle. (Korean J Oral Maxillofac Radiol 2007; 37 : 191-5 )
