Odontogenic tumors in Mexico

Odontogenic tumours: a retrospective study of 1642 cases in a Chinese population

“…A predominance of young age groups was also shown in other series 1,5,7,10,17 . There was a predilection for females observed in this series which was in accordance with the data from previous reports 5,7,9,11,15 but not with those reported by ADEBAYO et al 1 and OCHSENIUS et al 10 AOT occurred equally in both jaws in the present study which was similar to the reports by OCHSENIUS et al 10 and OLGAC et al 12 , while this tumour was more frequently maxillary than mandibular by a ratio of 1.5:1-3.5:1 in other series 1,2,7,9,15 .…”

“…The high frequency of ameloblastoma and low frequency of odontoma are consistent with the data from Africa 1,2,7,11,16 , whereas in most of the American studies 4,9,10,15 and the study from Estonia 17 odontoma occurred with the highest frequency. These discrepancies probably 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.…”

“…The rarity of squamous odontogenic tumour (SOT), calcifying epithelial odontogenic tumour (CEOT) and cementoblastoma (CB) was comparable to findings reported elsewhere 1,2,4,5,7,[9][10][11][12][15][16][17] . Only five cases of odontogenic fibroma (OF) were found, while this tumour was more frequent in other series 1,2,4,5,7,[9][10][11][12]16 (1.2-13.8%).…”

“…The distribution of OTs between maxilla and mandible was in keeping with most previous reports 1,2,7,10,11,15 . The marked preference for the mandible in this study (4.0:1) and Nigerian reports 1,2,7,11 (2.9:1-5.7:1), in contrast to the American 5,9,10,15 and European 12,17 series (1:1-2:1), could be explained by the prevalence of ameloblastoma.…”

“…When the 1992 WHO classification was used, OM composed 7.2% of all the OTs in this study and 4.7-17.7% in previous reports 1,2,4,5,7,[9][10][11][12][15][16][17] (Table 4). A female preponderance was found in this series and large series from elsewhere 1,2,5,7,9-12 with malefemale ratios of 1:1.1-1:2.8.…”
