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.

“…Some papers have reported that this tumor is more frequently found in the maxilla 4,13,17 and in female patients. 17 (Table 1); these findings were confirmed in our study, in which 53.9% of these lesions were found in the maxilla (Table 3) and 77% of these patients were female (Table 1), mostly in the second decade of life (7 of 13 cases) ( Table 2).…”

“…These tumors are 2.5% of all biopsied lesions in dental offices. 2,3 Although many retrospective studies have been conducted in Africa, 4,5,6 Asia, 7 Europe, 8,9 and North America, 10 unanswered question still remain about the relative frequency and the incidence of certain odontogenic tumors. 11 The geographical distribution of these lesions is variable.…”

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.

“…1 Despite its importance in health planning, few reports on the worldwide pattern of oral and maxillofacial surgical diseases are available. In Nigeria, there are considerable data on specific surgical conditions such as facial fractures, [2][3][4] tumors [5][6][7] and other maxillofacial conditions. [8][9][10] However, reports of the overall pattern of presentation to oral and maxillofacial surgical treatment centers in Nigeria are quite few.…”

Background:The worldwide pattern of oral and maxillofacial surgical conditions has been rarely reported despite its significance in head and neck medicine. The Niger Delta region comprises 9 of the 36 states in the Federal Republic of Nigeria. There are scanty reports on oral and maxillofacial surgical diseases from the region despite its 95% contribution to Nigeria's oil-revenue. Methods: This retrospective survey of oral/maxillofacial surgical cases seen at a referral center in Port Harcourt, a city in the Niger delta region of Nigeria. Results: Between 2000 and 2004, our center offered specialized maxillofacial surgical services to 86 patients coming from 5 states in the Niger delta region. These patients made up 20% of all patients seen at the department within the period. There were 110 indications for surgical interventions. Most were complaints of trauma (46.4%). The rest were tumors and allied lesions (39.0%) and cysts (12.7%). Ratio of male to female patients was 1.7:1 while patients were aged between 9 and 85years (mean 31.2years, standard deviation ±15.4). Most (n = 63, 73%) had surgical treatment while a significant proportion (19%) defaulted. Seventy -nine surgical procedures were performed (69 primary and 10 secondary). Primary procedures included maxillo-mandibular fixation (31.9%) and enucleation of tumor/cyst (17.4%). While our series of 86 cases over 4years appears low, there is likelihood that oral and maxillofacial surgical conditions are as common in the Niger Delta region as in other parts of Nigeria. There is scarcity of skilled manpower and equipments for the management of oral maxillofacial surgical conditions in the region. Health promotion activities are needed to improve awareness for early diagnosis of these conditions. Also, poverty alleviation measures need to be effective as defaults were often due to inability to pay for treatment. Conclusion: In many parts of the Niger Delta region of Nigeria, oral and maxillofacial surgical diseases are not uncommon causes of morbidity. However, many parts of the region lack requisite manpower for prevention and curative health activities. Defaults from hospital treatment were due to preference for traditional (unorthodox) measures and financial inability. Poverty alleviation measures need to be stepped up while the state of medical infrastructure should be enhanced in the region.
