A Review of 318 Odontogenic Tumors in Kaduna, Nigeria

Tumores odontogênicos: estudo clínico-patológico de 238 casos

“…The incidence was slightly higher in females (Table 1); this finding has not been demonstrated in other studies, such as that by Mosqueda-Taylor et al 18 There were two age-related peaks in both genders; the highest peak was in the second and third decades of life, and a lower peak occurred in the seventh decade of life (Table 2). These findings are similar to those of Ahlfors et al 19 The ameloblastoma was the second most common tumor in this study (23.7%) ( Table 2); its frequency was lower compared to published reports by Lu et al 7 (59%), Oduyoka6 (58%) and Adebayo et al 5 (48%). The ameloblastoma is considered as the most common histological type in Africa, followed by the odontogenic mixoma.…”

“…10,19 In our study, the frequency of ameloblastoma was higher in males (52.6%) ( Table 1), as also seen in studies conducted in Nigeria5 and Turkey; 8 most of these patients had no tumor-related symptoms (79%; p=0.023) ( Table 4). Findings in African studies have shown that the prevalence of this tumor is higher in the second to fourth decades of life, 5,17 and that they are located preferably in the mandible, 7,17 both of which were confirmed in our study (Tables 2 and 3).…”

“…5,6,10 This was the most common of these tumors in the Americas, as reported by Ochsenius et al, 14 MosquedaTaylor et al, l3 and Daley et al; 10 odontomas are least frequent in Africans 6 and Chinese. 7 There were 54 cases of odontomas in our 15-year study (22.1%) ( Table 2).…”

“…This neoplasm was diagnosed mostly in patients aged below 30 years; published papers have reported that new odontomas are discovered up to the third decade of life. 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.…”

“…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.…”
