The literature on the oral health status of Down syndrome (DS) patients is controversial. Therefore, the purpose of this study was to assess the oral health status and levels of mutans streptococci (MS) in the saliva of DS children.
This study was performed with 60 DS children and 71 non-DS children aged six to 12 years old. Caries experience, plaque index (PI), and gingival bleeding index (GBI) were recorded. Information about oral hygiene habits was obtained. Saliva samples were collected to determine MS levels.
The prevalence of dental caries was similar in children with and without DS. DS children had lower PI and GBI values and a higher toothbrushing frequency. Supervised toothbrushing by parents or guardians was more frequent in DS children and associated with lower PI and GBI. High counts of MS in saliva were associated with caries experience in DS children.
Down syndrome children had a similar caries experience, lower plaque index, and lower gingival bleeding index values compared to children without Down syndrome. However, DS children who had caries were more likely to display high counts of mutans streptococci in saliva than non-DS children with caries.
关于唐氏综合征（DS）患者口腔健康状况的文献存在争议。因此，本研究的目的是评估DS儿童的口腔健康状况以及唾液中变形链球菌（MS）的水平。
本研究对60名6至12岁的DS儿童和71名非DS儿童进行。记录龋齿经历、菌斑指数（PI）和牙龈出血指数（GBI）。获取有关口腔卫生习惯的信息。收集唾液样本以确定MS水平。
患有和未患有DS的儿童龋齿患病率相似。DS儿童的PI和GBI值较低，刷牙频率较高。DS儿童中由父母或监护人监督刷牙的情况更为频繁，且与较低的PI和GBI相关。唾液中MS计数高与DS儿童的龋齿经历相关。
与非唐氏综合征儿童相比，唐氏综合征儿童有相似的龋齿经历、较低的菌斑指数和较低的牙龈出血指数值。然而，患有龋齿的DS儿童唾液中变形链球菌计数高于患有龋齿的非DS儿童。
