Assess prevalence, familial predisposition and susceptibility to caries of Black Stains (BS). Evaluate the microbiological
composition of BS, saliva and subgingival plaque.
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.
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.
