AIM
Assess prevalence, familial predisposition and susceptibility to caries of Black Stains (BS). Evaluate the microbiological composition of BS, saliva and subgingival plaque.
MATERIALS AND METHODS
Sixty nine subjects with BS (test group) and 120 subjects without BS (control group) were analysed for oral status. For each BS-patient, a BS-deposit, 1 ml of saliva and subgingival plaque were collected and microbiologically analysed. Five deciduous teeth with BS were observed under SEM.
RESULTS
This study showed a BS prevalence similar to that of the Mediterranean area and a familiality. The microbiological origin of BS was confirmed by SEM and culture method and the BS flora differ from that of supragingival plaque.
CONCLUSIONS
Predominance in BS and saliva of Actinomycetes and the low salivary prevalence of S. mutans and L. acidophilus may be related with low caries incidence in BS patients. The high presence of Actinomyces spp can be a causative factor for BS.
目的
评估黑色牙渍（BS）的患病率、家族易感性和龋齿易感性。评估黑色牙渍、唾液和龈下菌斑的微生物组成。
材料与方法
对69名有黑色牙渍的受试者（试验组）和120名无黑色牙渍的受试者（对照组）进行口腔状况分析。对于每例有黑色牙渍的患者，采集一份黑色牙渍沉积物、1毫升唾液和龈下菌斑并进行微生物学分析。在扫描电子显微镜下观察5颗有黑色牙渍的乳牙。
结果
本研究显示黑色牙渍的患病率与地中海地区相似且存在家族性。通过扫描电子显微镜和培养方法证实了黑色牙渍的微生物来源，且黑色牙渍菌群与龈上菌斑不同。
结论
放线菌在黑色牙渍和唾液中占优势，而变形链球菌和嗜酸乳杆菌在唾液中的患病率较低，这可能与黑色牙渍患者龋齿发病率低有关。放线菌属的高存在可能是黑色牙渍的一个致病因素。
