The aim was to report the prevalence of oral diseases/conditions among a Ugandan population.
Subjects aged 12 (n=696) and 35-44 years (n=396) were chosen from randomly selected urban and peri-urban areas of Arua, Mbale, Kampala and Mbarara districts. They were clinically examined by 4 trained and calibrated dentists for oral diseases/conditions using criteria described by World Health Organisation.
Dental caries (DMFT >or=1) was recorded in 40% and 62.5% of the children and adults, respectively. The overall mean DMFT score was 0.9 for children and 3.4 for adults. Caries was significantly more severe in females as compared to males in children (p<0.05), whereas in adults, there was no significant gender difference. Kampala had a significantly higher mean DMFT score compared to other districts in all age groups (p>0.05). Culculus deposits were generally, more prevalent in adults as compare to children except in Mbarara district. Gum bleeding was also significantly more prevalent among children as compared to adults (p<0.05). Significantly higher prevalence of gum bleeding in both children and adults was recorded in Arua district as compared to other areas (p<0.05). Each of the age groups had a prevalence of malocclusion of 61%. However, the severity of malocclusion varied between age groups and districts. The prevalence of dental fluorosis was 3% and 4% for children and adults, respectively. All subjects in Arua district were fluorosis-free. Tetracycline enamel staining was less than 1% in both age groups. Enamel attrition was more prevalent in adults as compared to children: 19% versus 1%.
The prevalence of oral diseases/conditions was generally low among the study population. Caries experience was significantly higher in the Kampala (urban) district as compared to rural districts in all age groups; the D - component being the major contributor.
本研究旨在报告乌干达人群口腔疾病/状况的患病率。
从阿鲁阿、姆巴莱、坎帕拉和姆巴拉拉地区随机选取的城市和城郊地区，挑选出年龄为12岁（n = 696）和35 - 44岁（n = 396）的受试者。由4名经过培训且校准合格的牙医，依据世界卫生组织描述的标准，对他们进行口腔疾病/状况的临床检查。
分别在40%的儿童和62.5%的成年人中记录到龋齿（DMFT≥1）。儿童的总体平均DMFT评分为0.9，成人为3.4。在儿童中，女性龋齿情况显著比男性严重（p<0.05），而在成年人中，性别差异不显著。在所有年龄组中，坎帕拉的平均DMFT评分显著高于其他地区（p>0.05）。除姆巴拉拉地区外，牙结石沉积总体上在成年人中比儿童更普遍。牙龈出血在儿童中也显著比成年人更普遍（p<0.05）。与其他地区相比，阿鲁阿地区儿童和成年人的牙龈出血患病率均显著更高（p<0.05）。每个年龄组的错颌畸形患病率均为61%。然而，错颌畸形的严重程度在年龄组和地区之间有所不同。儿童和成年人的氟斑牙患病率分别为3%和4%。阿鲁阿地区的所有受试者均无氟斑牙。两个年龄组的四环素牙釉质染色均低于1%。牙釉质磨损在成年人中比儿童更普遍：分别为19%和1%。
研究人群中口腔疾病/状况的患病率总体较低。在所有年龄组中，坎帕拉（城市）地区的龋齿发生率显著高于农村地区；D部分是主要促成因素。
