“…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 Odontomas were more prevalent in the Tumor 1 100 --TOTAL 58 180 p=0,023 -chi-square test maxilla (57.5%) ( Table 3) and in females (68.6%) ( Table 1); this is similar to the findings of Santos et al 13 The incidence of the odontogenic mixoma was 6.3% of all odontogenic tumors in our study (Table 2), which is about two times less than that reported by MosquedaTaylor et al, 3 but comparable to North-American studies. 10 Our study revealed a slightly higher prevalence of this tumor in males (Table 1); Ladeinde et al 12 and Odukoia et al 6 have reported a higher frequency in females. This study showed that the mean age of these patients was 29 years, higher than the age reported in two previous studies in Nigeria 5 and Mexico, 11 in which the mean age was 19 years.…”

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.

“…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.

“…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).…”
