摘　　要：目的:了解赞比亚7～12岁小学生龋齿的患病情况,为该地区制定小学生龋病的防治提供基本资料。方法:对赞比亚首都卢萨卡CHAWAMA BASIC SCHOOL 1 932名小学生在室内自然光下检查乳、恒牙的患龋情况,并记录DMFT值,统计分析各年龄组以及各牙位之间的患龋情况。结果:7～12岁的乳牙患龋率8.70%,龋均2.17;恒牙患龋率3.78%,龋均1.41。患龋率随着年龄的增长而增长(P<0.05)。女生比男生患龋率高,但无统计学意义(P>0.05)。乳牙充填率4.44%,患龋最多的为下颌乳磨牙,其次为上颌乳磨牙;恒牙的龋齿充填率3.31%,患龋最高的是下颌第一磨牙。结论:赞比亚小学生龋齿的患病率较低,但龋齿的充填率也很低,应当加大口腔保健的服务力度,提高龋齿充填率。AIM： To investigate the caries prevalence in children aged 7 to 12 years in Zambia , so as to provide the evidence for the establishment of oral health care policies for the students in primary school. METHODS ： 1932 primary school students aged 7 to 12 years living around Lushaka,the capital city of Zambia , were clinically ex- amined under natural condition. The draft and DMFT of the subjects was assessed. Data were statistically analysised by SPSS 12.0 software. RESULTS： The constituent ritio of draft was 8. 70% （d, the highest was found in mandibular molars）, 2.17 （xdmft） and 4.44% （f）, that of DMFT 3.78% （D, the highest was found in mandibular first molars）, 1.41 （xDMFT） and 3.31% （F）. The caries prevalence of permanent teeth increased with age （ P 〈 O. 05 ）. No statis- tical difference of caries prevalence was found between boys and girls （ P 〉 0.05 ）. CONCLUSION ： In Zambia preva- lence of dental caries in pupils is low, but filling rate of the caries teeth is also yery low. Dental healthy service should be improved.
