“…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).…”

“…This data is higher than previously studies reported in North America (6,7), South America (8-12) and Europe (13,14), as they presented a frequency lower than 3%. On the other hand, in Asia and Africa OTs represented 8.99 and 9.6%, respectively, of all oral lesions (15,16), although an Iranian series had a frequency of 1.9% (17). Abbreviations: odontogenic tumors = OTs; keratocystic odontogenic tumor = KCOT; ameloblastoma = AMB; odontoma = 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.

“…Similarly in studies conducted on Libyan and Brazillian population showed KCOT to be the most common type (El-Gehani et al, 2009, Daniela et al, 2012. Likewise it was also reported the commonest OT in Chinese population (Luo and Li, 2009). This difference in frequencies of these lesions between developing and developed countries might be the result of better health education and facilities in the developed nations; odontoma being asymptomatic lesions are usually diagnosed on radiographic examinations.…”

“…They arise either from epithelial or ectomesenchymal tissues or both; parts of the tooth forming tissue (Barnes et al, 2005). Their reported frequency in different populations of the world varies, ranging from 1% to 9.6% of all tumours of the jaw (Ladeinde et al, 2005;Sriram and Shetty, 2008;Luo and Li, 2009;Saghravanian et al, 2010). According to the most recent WHO (World keratocyst is considered as a benign cystic neoplasm known as Keratocystic Odontogenic Tumour (KCOT) (Barnes et al, 2005).…”

“…While we had a prevalence rate of 2.9%, that of the rest of the world ranged from 0.9 to 12.5%. Studies from Srilanka [12] and Brazil [9] and China [6] ranged from 8.3 to 9.3%. These studies however did not study the lesions from the bone related lesions namely Simple bone cyst, Aneurysmal bone Cyst, Cherubism, Central giant cell lesion (granuloma), Osseous Dysplasia, Fibrous Dysplasia and Ossifying Fibroma.…”

Aim To analyze the relative frequency of different types of odontogenic tumors based on the WHO 2005 histopathological classification of odontogenic tumours and to compare the data with published literature. Methods Data collected from seven different hospitals in the same region of the city (south Chennai) were systematically searched for all cases of odontogenic tumors operated on between the years 2005-2010. The histopathology slides of the tumours were reanalyzed for cross verification. The data were also checked for duplication and for recurrence cases. Age, gender and site prevalence were also studied. Results Of the 107 cases collected, with full records, 60 (56%) were odontomas. The second most common was ameloblastoma (14%), followed by Keratocystic odontogenic tumour (13%). The rest of the tumours formed 17% of the total. Conclusions A comprehensive tumour database should be initiated so that cross referring of cases would be easier and the patients, surgeons and the pathologists would be able to safe guard the information about the tumour for future reference. Many private hospitals lack the facility to store and catalogue histopathological evidences for a prolonged period of time.
