To investigate the prevalence of dental caries of 4-year-old children in Miyun District of Beijing by international caries detection and assessment system (ICDAS), to detect the caries activity Cariostat value and to analyze the correlation between the Cariostat value and dental caries.
Totally 815 children aged 4 years in 7 kindergartens in Miyun District of Beijing were recruited. The clinical examination of all children was conducted by one examiner using ICDAS. The oral de-birs and plaques were collected by one doctor who recorded the Cariostat scores. The results of clinical examination were compared between genders. At the same time, the prevalence of dental caries, the mean dft/dfs and dft/dfs among high Cariostat scores group (2.0-3.0), medium Cariostat scores group (1.5) and low Cariostat scores group (0-1.0) were compared. The distributions of incipient caries in different Cariostat scores groups were compared among children with incipient caries only.
All the children had incipient caries, and 78.3% of the children had cavitated caries with ICDAS score of 3 or above. The mean dt scores were 9.76±3.65, the mean dft scores was 4.64±4.43 and the mean dft scores were 14.41±3.42. The incipient caries with ICDAS score of 1-2 were widely distributed, accounting for 67.7% of the total numbers of caries. There was no significant diffe-rence in caries prevalence and caries experience between genders (>0.05). The proportion of children with high Cariostat scores in boys (43.6%) was higher than that in girls (33%) and the difference was statistically significant (<0.05). With the increase of Cariostat scores, the prevalence of cavitated caries, the mean dft/dfs and dft/dfs scores in children was on the increase and the difference among the three groups was statistically significant (<0.05). For children with incipient caries only, the distribution of incipient caries in different Cariostat scores groups was no significant difference (>0.05).
ICDAS can detect early enamel demineralization of deciduous teeth in children. The prevalence of dental caries among 815 4-year-old children in Miyun District of Beijing is more serious, and incipient caries is widely distributed in children. Cariostat value reflects the status of cavi-tated caries and has no correlation with the distribution of incipient caries. Therefore, the combined application of ICDAS and Cariostat caries activity detection method is helpful for the detection of incipient caries and screening of caries high-risk children, which has great significance for the comprehensive ma-nagement of caries in children and the formulation of early preventive measures.
采用国际龋病检测与评估系统（ICDAS）调查北京市密云区4岁儿童的龋病患病率，检测龋活性试验（Cariostat）值，并分析Cariostat值与龋病之间的相关性。
选取北京市密云区7所幼儿园的815名4岁儿童。由一名检查者使用ICDAS对所有儿童进行临床检查。由一名医生收集口腔碎屑和菌斑并记录Cariostat评分。比较不同性别儿童的临床检查结果。同时，比较高Cariostat评分组（2.0 - 3.0）、中Cariostat评分组（1.5）和低Cariostat评分组（0 - 1.0）的龋病患病率、平均龋失补牙数（dft/dfs）。仅对患初期龋的儿童比较不同Cariostat评分组中初期龋的分布情况。
所有儿童均有初期龋，78.3%的儿童有龋洞形成，ICDAS评分为3及以上。平均龋面均（dt）为9.76±3.65，平均龋失补牙面均（dft）为4.64±4.43，平均龋失补牙数（dfs）为14.41±3.42。ICDAS评分为1 - 2的初期龋分布广泛，占龋病总数的67.7%。不同性别间龋病患病率和龋病经历差异无统计学意义（>0.05）。男孩中Cariostat高评分儿童的比例（43.6%）高于女孩（33%），差异有统计学意义（<0.05）。随着Cariostat评分升高，儿童龋洞形成患病率、平均dft/dfs和dfs评分均升高，三组间差异有统计学意义（<0.05）。仅对患初期龋的儿童而言，不同Cariostat评分组中初期龋的分布差异无统计学意义（>0.05）。
ICDAS能检测儿童乳牙早期釉质脱矿。北京市密云区815名4岁儿童龋病患病率较高，初期龋在儿童中分布广泛。Cariostat值反映龋洞形成情况，与初期龋分布无关。因此，联合应用ICDAS和Cariostat龋活性检测方法有助于初期龋的检测和龋病高危儿童的筛查，对儿童龋病的综合管理及早期预防措施的制定具有重要意义。
