A comparative study of odontogenic keratocysts associated with and not associated with an impacted mandibular third molar

Odontogenic cysts: a clinical study of 90 cases

“…The femalemale ratio was 1.1:1 which is consistent with one previous report (22). The localization of OKCs in this study was also quite similar to the findings of previous reports (14,15,19,26,27).…”

“…In contrast to previous studies (23)(24)(25)(26), no male predilection was apparent in our patient group. The femalemale ratio was 1.1:1 which is consistent with one previous report (22).…”

Reliance on Diagnostic Elements in Panoramic Imaging with Focus on Ameloblastoma and Keratocystic Odontogenic Tumor: Psychometric Study

“…Most articles regarding jaw bone lesions with well-defined margins and radiolucency have focused on comparisons between radiographic features such as frequencies of adjacent tooth root resorption 13) , positional relationships between an adjacent tooth and a lesion 6,14) , marginal shapes 15) , size of lesion and its association with presence or absence of impacted teeth 14) and interior radiographic appearance of the lesion 8) . Ameloblastomas are generally characterized as expansile, with a radiolucent appearance and a smooth periphery, and are often uni-or multiloculated with a characteristic "soap bubble-like" appearance.…”

“…Uni-or multi-locular radiolucent lesions such as ameloblastoma (AB), in particular, and odontogenic keratocysts, which have now been officially reclassified as keratocystic odontogenic tumors (KOT) by the World Health Organization 1) , are very difficult to differentiate on panoramic radiographs 10) , although this does not apply to desmoplastic AB. Most previous articles focusing on the differential diagnosis of radiolucent jaw lesions on panoramic radiographs have analyzed individual radiographic elements in fragments, such as size, morphological characteristics, marginal conditions, lesion density, location with regard to adjacent tooth structures, radicular state of adjacent teeth, cortical involvement and other factors 2,6,[13][14][15] . However, both AB and KOT resemble each other in the image findings for these radiographic elements.…”

Estudo retrospectivo de 24 tumores odontogênicos queratocísticos, com correlações clínico-imaginológicas, histopatológicas e cirúrgicas

“…Associação com dentes não-erupcionados ocorreu em 22% a 52,8% dos TOQs, gerando imagem folicular semelhante à do cisto dentígero (BROWNE, 1970;BROWNE, 1971;CHOW, 1998;MCIVOR, 1972;PARTRIDGE;TOWERS, 1987;TSUKAMOTO et al, 2002;ZHAO;WEI;WANG, 2002). Essa relação folicular é creditada ao desenvolvimento neoplásico no trajeto de erupção dental, com conseqüente interrupção desse processo (TSUKAMOTO et al, 2002 2006;CHOW, 1998;FORSSELL, 1980).…”
