“…13 Lesions such as the squamous odontogenic tumor and the ameloblastic fibrodontoma were found in a single case each; both were females and presented mandibular pain. Our study confirmed the low frequency of these neoplasms as shown in other studies, 3,7,12,14 which underlines their rarity.…”

“…5,6,10 This was the most common of these tumors in the Americas, as reported by Ochsenius et al, 14 MosquedaTaylor et al, l3 and Daley et al; 10 odontomas are least frequent in Africans 6 and Chinese. 7 There were 54 cases of odontomas in our 15-year study (22.1%) ( Table 2).…”

“…2 Few published studies have been done on large series in any country or region to assess age, gender and site of odontogenic tumors, based on the 1992 classification of the World Health Organization. 3,6,7,14,17 As of 2005, a new classification included the odontogenic keratocyst as one of the odontogenic tumors, renaming it as a keratocystic odontogenic tumor. This was the most prevalent lesion in this study (30%) ( Table 2); given its recent reclassification, it was not possible to compare its prevalence with that of other odontogenic tumors or with findings published elsewhere.…”

Odont ogenic tumors are neoplasms that develops exclusively in the gnathic bones; they originate from odontogenic tissues, by epithelial or mesenchymal proliferation, or both. Aim: To evaluate the incidence of odontogenic tumors in a specific institution, and to compare these findings with other studies in the literature. Study format: A cross-sectional cohort retrospective study. Material and method:The sample was obtained from the files of patients with odontogenic tumors diagnosed between January 1992 and March 2007 (15 years). Cases in which the diagnosis could be adapted to the new World Health Organization (WHO) of 2005 were included. Data such as gender, age, anatomical site, histological type and symptomatology were analyzed. Results: Odontogenic tumors were 4.76% of all biopsied lesions within the studied period. The mean age was 30.7 years; 57% of the patients were male. The keratocystic odontogenic tumor was the most prevalent histological type (30%), followed by the ameloblastoma (23,7%). The rate of asymptomatic cases was 75.7%. Conclusion: Odontogenic tumors occurred more frequently in females, in the second and third decades of life, and more commonly in the mandible; most cases were asymptomatic.

“…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). KCOT was the most prevalent OT in this study, followed by AMB and ODO.…”

“…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). We have observed a greater incidence of OTs in the female gender, result also found by Gaitán-Cepeda et al (30).…”

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.
