To retrospectively document the pattern of occurrence of odontogenic tumours in Tanzania over fifteen years.
The histologic types, site, age and sex distribution of odontogenic tumours in Tanzania from 1982 to 1997 were reviewed. Records of patients who presented to the four referral centres in Tanzania and who had histologically proven oral tumours and tumour-like conditions were examined.
Odontogenic tumours comprised about 12.2% of all oral tumours and tumour-like conditions. The majority of odontogenic tumours (55.3%) were seen in patients below 30 years of age and they more commonly affected the mandible than maxilla. Ameloblastoma was the most commonly seen odontogenic tumour (73.7%), followed by odontogenic myxoma (10.3%). The site, sex, and histologic distribution of ameloblastoma did not differ from other African studies. Over 50% of patients with ameloblastoma presented to hospital late (after three or more years).
In order to improve on the treatment outcome, the need for early detection and referral of patients by medical personnel and dentists is stressed.
回顾性记录坦桑尼亚15年间牙源性肿瘤的发病模式。
对1982年至1997年坦桑尼亚牙源性肿瘤的组织学类型、部位、年龄及性别分布进行回顾。检查了在坦桑尼亚四个转诊中心就诊且经组织学证实患有口腔肿瘤及肿瘤样病变的患者记录。
牙源性肿瘤约占所有口腔肿瘤及肿瘤样病变的12.2%。大多数牙源性肿瘤（55.3%）见于30岁以下患者，且下颌骨受累比上颌骨更常见。成釉细胞瘤是最常见的牙源性肿瘤（73.7%），其次是牙源性黏液瘤（10.3%）。成釉细胞瘤的部位、性别及组织学分布与其他非洲研究无差异。超过50%的成釉细胞瘤患者就医时已属晚期（三年或更长时间后）。
为改善治疗效果，强调医务人员和牙医对患者进行早期发现和转诊的必要性。
