Digital image filters are not necessarily related to improvement in diagnostic of degenerative bone changes in the temporomandibular joint on cone beam computed tomography

This study assessed whether the use of digital image filters influences detection temporomandibular joint (TMJ) bone changes on cone beam computed tomography (CBCT). Two radiologists evaluated TMJ images CBCT scans to verify presence osteophytes, erosions, pseudocysts, sclerosis and flattening, using software XoranCAT®; each was with without following filters: Angio Sharpen 3x3 5x5. Kruskal-Wallis’ test used assess application influenced scores assigned degenerative in condyle. Flattening present 15 cases (51.72%), followed by osteophytes six (20.69%), three (10.34%), erosion pseudocyst found two (6.90%). No statistically significant difference (P = 0.786) regarding original those treated both filters. Digital our did not influence diagnosis images.
