Dental caries is the most common childhood disease and the most frequent non-communicable disease worldwide. In developing countries, a vast majority of the caries remains unrestored. However, the severity and consequences of untreated dental caries among Nigerian children is unknown.
To determine the prevalence using the DMFT/dmft index and severity of oral conditions related to dental caries using the PUFA/pufa index in suburban Nigerian children.
The study population consisted of 1,266 randomly selected school children in Ile-Ife, Nigeria. Dental caries status was assessed using the DMFT/dmft index, described by WHO for epidemiological studies. The PUFA/pufa index was used to assess the clinical consequences of untreated dental caries.
The mean dmft was 0.58 for the 4-6 years age group while the mean pufa score was 0.16 for the same age group. The mean DMFT score (0.16) was highest for the 13-16 years age group, while the mean PUFA score was 0.05 for the same age group. The prevalence of dmft > 0 was highest in the 4-6 years age group (16.9 %) while the prevalence of DMFT > 0 was highest in the 13-16 years age group (7.2 %). The mean pufa > 0 was highest in the 4-6 years age group (9.2 %). The overall caries prevalence was highest in the 4-6 years age group (17.4 %). Thirty-three percent of decayed teeth in the permanent dentition and 28.2 % of the primary dentition had signs of odontogenic infections.
Despite the increase in the consumption of westernised diets by Nigerian children coupled with limited access to dental care, the prevalence was low but the clinical consequences of untreated dental caries was still high.
龋齿是全球最常见的儿童疾病和最频发的非传染性疾病。在发展中国家，绝大多数龋齿未得到治疗。然而，尼日利亚儿童中未治疗龋齿的严重程度和后果尚不清楚。
使用DMFT/dmft指数确定尼日利亚郊区儿童龋齿的患病率，并使用PUFA/pufa指数确定与龋齿相关的口腔状况的严重程度。
研究人群包括尼日利亚伊费随机选取的1266名在校儿童。使用世界卫生组织描述的用于流行病学研究的DMFT/dmft指数评估龋齿状况。使用PUFA/pufa指数评估未治疗龋齿的临床后果。
4 - 6岁年龄组的平均dmft为0.58，而同一年龄组的平均pufa评分为0.16。13 - 16岁年龄组的平均DMFT评分（0.16）最高，而同一年龄组的平均PUFA评分为0.05。dmft > 0的患病率在4 - 6岁年龄组最高（16.9%），而DMFT > 0的患病率在13 - 16岁年龄组最高（7.2%）。平均pufa > 0在4 - 6岁年龄组最高（9.2%）。总体龋齿患病率在4 - 6岁年龄组最高（17.4%）。恒牙列中33%的龋坏牙和乳牙列中28.2%的龋坏牙有牙源性感染迹象。
尽管尼日利亚儿童西式饮食的摄入量增加，且获得牙科护理的机会有限，但龋齿患病率较低，但未治疗龋齿的临床后果仍然很高。
