A study of the prevalence and severity of attrition in both anterior and posterior teeth has been conducted in two rural communities in Nigeria. 5984 teeth in 190 subjects were examined. Age range of the subjects was from 15-55 years and 58.9% of them were male, while 41.1% were female. The number of subjects with little or no attrition increased with increasing age while varying degrees of severity of attrition increased with increase in age. Attrition was more marked in the mandibular teeth (56.52%) than in the Maxilla (46.71%). The first molar was the most consistently attrited and since tooth attrition can be a cause of neuralgia in the oral region, dentine exposure due to severe attrition should be considered in the differential diagnosis of pain in and around the mouth.
在尼日利亚的两个农村社区开展了一项关于前牙和后牙磨耗患病率及严重程度的研究。对190名研究对象的5984颗牙齿进行了检查。研究对象的年龄范围为15至55岁，其中58.9%为男性，41.1%为女性。磨耗轻微或无磨耗的研究对象数量随年龄增长而增加，而不同严重程度的磨耗程度则随年龄增长而增加。下颌牙的磨耗（56.52%）比上颌牙（46.71%）更明显。第一磨牙是磨耗最持续的牙齿，由于牙齿磨耗可能是口腔区域神经痛的一个原因，在口腔及周围疼痛的鉴别诊断中应考虑严重磨耗导致的牙本质暴露。
