“…Regarding age, there was a higher incidence in the second and third decades of life, being rare after the seventh decade. These findings are similar to the ones reported by Luo and Li (16), da-Costa et al (18) and Johnson et al (22). The mandible was 2.5 times more common than the maxilla which is similar to previous studies (8,18,21,22).…”

“…Corroborating with other studies (12,(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30), in our sample, benign tumors were prevalent. This low frequency of malignant tumors is similar to those reported in others countries (7)(8)(9)(10)(11)(12)19), but it is different than those reported in China that present more than 5% of cases as malignant tumors (16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29).…”

“…Several retrospective studies of OTs published previously to the latest WHO classification (5) reported AMB and ODO being the most common tumors (7,13,19,29). However, the inclusion of KCOT has not only produced an increase in the frequency and prevalence of OTs, but also has modified the order of distribution of these tumors, making KCOT one of the most common OTs (18)(19)(20)(21)(22)30). OTs are uncommon lesions in the studied population and are represented mainly by the KCOT, AMB and ODO.…”

Background: Odontogenic tumors (OTs) are considered important among oral lesions because of their clinicopathological heterogeneity, and variable biological behavior. This paper aims to determine the frequency and distribution of OTs, over a period of 10 years, at a public university in Northeastern Brazil and compare this data with previous reports. Material and Methods: We reviewed all cases of OTs from oral pathology laboratory of University of Pernambuco (UPE), from 2004 to 2014. Diagnoses were re-evaluated and the tumors were classified according to the latest (2005) World Health Organization Classification of Tumors. In addition, we searched in the English-language literature retrospective studies on OTs that used the same classification. Results: Within the total of 6028 oral biopsies, 289 (4.79%) were OTs. Of these, 287 (99.3%) were benign and 2 (0.7%) were malignant. The overall incidence was 31.1/million. Mandible-maxilla ratio was 2.5:1 and mean age 35 years. Keratocystic odontogenic tumor (KCOT) (34.6%) was the most frequent lesion, followed by ameloblastoma (AMB) (32.9%) and odontoma (ODO) (11.4%). Conclusions: OTs are uncommon neoplasms with geographic variation. Our clinicopathological features are according to literature. In the present study, KCOT was the most frequent one, showing that the new classification of OTs altered the distribution of these lesions and possibly made KCOT the most common OT observed in diagnostic services worldwide.
