The practice of extraction of ebinyo or false teeth is based on the belief that the rubbing of herbs on the gum (in the region of the canine) or the removal of the primary and/or permanent canine tooth buds will lead to the relief of childhood fevers and diarrhoea. The reported prevalence of this practice in Uganda and neighbouring countries is varied.
A survey carried out in Kampala to determine the occlusal traits of fourteen-year-old children offered an opportunity to assess the effects of ebinyo (a dental mutilation based on local customs and superstitions) on the occlusal status of the sample population.
402 children aged fourteen years were examined according to the criteria of the Federation Dentaire Internationale Commission on Classification and Statistics for Oral Conditions method for measuring occlusal traits (COCSTOC-MOT) proposed by Baume et al. (1973).
The most common dental anomaly was teeth missing due to extraction or trauma. Canines (28%) and mandibular first molars (28%) exhibited the highest frequency. Missing canines were four times more common in girls than boys, and three times greater in the maxilla than the mandible. Canines also accounted for 12.8% of the malformed teeth observed in the study.
The results of this study show that the practice of ebinyo, although carried out early in the life of the child, can impact on the occlusal status in the permanent dentition years later.
拔除“埃宾约”(ebinyo)或乳牙的做法基于这样一种观念,即在牙龈(犬齿区域)上摩擦草药或拔除乳牙和/或恒牙的犬齿牙胚会缓解儿童发热和腹泻。据报道,这种做法在乌干达和邻国的流行程度各不相同。
在坎帕拉进行的一项调查旨在确定14岁儿童的咬合特征,这为评估“埃宾约”(一种基于当地习俗和迷信的牙齿 mutilation)对样本人群咬合状况的影响提供了机会。
根据鲍姆等人(1973年)提出的国际牙科联合会口腔状况分类和统计委员会测量咬合特征方法(COCSTOC-MOT)的标准,对402名14岁儿童进行了检查。
最常见的牙齿异常是因拔牙或外伤导致的牙齿缺失。犬齿(28%)和下颌第一磨牙(28%)出现的频率最高。缺失的犬齿在女孩中比男孩中常见四倍,在上颌中比下颌中多三倍。犬齿在该研究中观察到的畸形牙齿中也占12.8%。
这项研究的结果表明,“埃宾约”的做法虽然在儿童早期进行,但可能会在多年后的恒牙列中影响咬合状况。
