The purpose of this study was to evaluate the prevalence of 680 odontogenic cysts diagnosed in Porto Alegre, RS, Brazil, and to compare results with findings in the literature. Data of odontogenic cysts diagnosed from 1985 to 2005 were collected from the files of the Oral Pathology Laboratory of Pontifícia Universidade Católica do Rio Grande do Sul, Porto Alegre, RS, Brazil, and entered in a standardized form for later comparisons. The most prevalent odontogenic cysts were radicular (72.50%), dentigerous (22.20%) and residual (4.26%) cysts. The mandible of white patients was the anatomic site and ethnic group most frequently affected by this disease. Four of the six types of cysts were more frequent in the second and fourth decades of life, and no significant differences were found between sexes in the diagnosis of odontogenic cysts.In conclusion, the prevalence of odontogenic cysts was similar to that reported in the literature, which shows that inflammatory cysts are the most frequent.

“…The percentage of odontomas was lower in the other studies from India that were based in government hospitals [18,19] when compared to ours. While one of the Nigerian study has not taken odontomas into account, Jing et al [16] comment that these discrepancies in the number of odontomas being lesser in their populations on comparison with the others is probably a result from geographic variation, but it should be mentioned that the incidence of odontoma in some countries was likely underestimated due to the unique clinical features of this tumour and insufficient hospital management. Most of these tumours exhibit self-limited growth and do not cause clinical symptoms.…”

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.

Introdução: O ameloblastoma é um tumor odontogênico de origem epitelial que, pela freqüência, subtipos clínicos, grande capacidade infiltrativa e alta tendência à recorrência tem merecido bastante atenção. Objetivo: Realizar estudo retrospectivo dos casos diagnosticados histopatologicamente de ameloblastoma no Serviço de Anatomia Patológica do Hospital Universitário Antônio Pedro da Universidade Federal Fluminense (HUAP/UFF) no período de 1997 a 2007. Material e métodos: Foram selecionados casos de ameloblastoma correspondentes ao período da pesquisa, e dados como idade, sexo, raça, localização da lesão, aspecto radiográfico, tipo de biópsia, diagnósticos clínico e histopatológico foram compilados das fichas de requisição e/ou prontuários. Resultados: Depois do levantamento e da revisão das lâminas para confirmação do diagnóstico de ameloblastoma, a amostra totalizada foi de 23 casos. Os pacientes mais acometidos eram do sexo masculino, leucodermas e estavam entre a primeira e a terceira década de vida. Todos os casos ocorreram na mandíbula, sendo a região posterior a mais afetada. Predominaram o aspecto radiográfico multilocular e, histopatologicamente, o padrão multicístico, sendo os subtipos folicular e híbrido os mais freqüentes. Não foram observados casos de ameloblastoma desmoplásico e de células basais. Conclusões: A freqüência do ameloblastoma varia de acordo com a região geográfica avaliada, e a realização de estudos retrospectivos pode contribuir para a identificação de grupos e dos possíveis fatores associados ao seu desenvolvimento.
