Objective: The aim of this study was to determine the association between clinical manifestations of sickle cell anemia (including hospitalization and pain crisis) and dental caries in children in Bahia. Material and Methods: The study design was crosssectional, and the population included children aged from 6 to 96 months from August 2007 to July 2008 (N = 686). Interviews were performed to identify the sociodemographic profiles of the participants, and oral examinations were conducted by three examiners who were previously trained and calibrated to identify the presence of dental caries according to World Health Organization (WHO) criteria. Logistic regression analysis was performed for confirmatory analysis and estimation of confidence intervals (CIs). Results: The results showed that pain crises and hospitalizations were positively associated with caries (crude odds ratio (OR) = 2.11 and adjusted OR = 1.24; crude OR = 2.50 and adjusted OR = 1.46, respectively), but these associations were not statistically significant. Conclusion: The severity of the sickle cell condition alone was not sufficient to aggravate the prevalence of caries; thus, there are no major differences in caries prevalence between children with and without sickle cell disease.KEYWORDSSickle cell anemia; Dental caries; Epidemiology; Paediatrics.

During the almost 50 years since Streptococcus mutans was first suggested as a factor in the etiology of dental caries, a multitude of studies have confirmed the cariogenic potential of this organism. Streptococci have been isolated from human and animal caries on numerous occasions and, with few exceptions, they are not typable by the Lancefield technique but are relatively homogeneous in their biochemical reactions. An analysis of the guanine-cytosine (G-C) composition of the DNA from strains K-1-R, NCTC 10449, and FA-1 by one of us (ALC) revealed significant differences and DNA-DNA reassociation experiments indicated that genetic heterogeneity existed among the three strains. The present electron microscopic study had as its objective the elucidation of any distinguishing morphological characteristics which might further characterize the respective strains.
