Abstract Background: Few studies consider the oral health status of adults with HIV in comparison with negative controls. This study aims to assess caries experience in Ugandan mothers according to HIV status, socio-behavioral-characteristics and gingival bleeding status and to examine whether HIV status modifies the association of socio-behavioral characteristics with caries experience. Secondly, using multilevel analysis this study also assessed to what extent site specific caries experience vary between and within individuals.Methods: This study uses data from the Ugandan site of the ANRS 121741 PROMISE- PEP trial (ClinicalTrials.gov, number NCT00640263) conducted in 2009-2013 that recruited mothers with HIV-1. In 2017 a comparison group of 181 HIV-1 negative controls was recruited. Caries experience was recorded using the World Health Organization’s Decayed, Missed and Filled teeth/surfaces (DMFT/DMFS) indices. Mixed effects logistic regression with the melogit program within Stata was conducted with DMFT/DMFS as the outcome and HIV-1 infection status as well as socio-behavioral characteristics as exposures. Results: Caries experience differed statistically significantly between HIV infected and non-infected mothers with 81% and 71% having DMFT>0, respectively. The corresponding mean and standard deviation were 4.6 (5.3) and 2.8 (3.2) respectively. Mixed effect logistic regression revealed significant positive associations between site specific caries and women’s age (OR=1.8, 95% CI: 1.1‒2.8), and presence of gingival bleeding (OR =2.0, 95% CI: 2.0 1.2‒3.2). Compared to premolar teeth, caries experience was more likely to occur in maxillary molars and mandibular molars and less likely to occur in incisors. The intra class correlation (ICC) for the correlation of individuals was 0.54 (95% CI: 0.48‒0.59). No two-way interactions terms between HIV-1 status and socio-demographic, behavioral and clinical covariates were observed. Conclusion: The prevalence of dental caries is higher in Ugandan mothers with HIV-1 than in uninfected Ugandan mothers and varies with mothers’, age, education and clinically recoded gingival inflammation. Socio-demographic differences in dental caries did not vary by HIV-1 status. We found that a multilevel random intercept model is appropriate and efficient for analyses of site specific dental caries data in the context of HIV-1 infected and uninfected Ugandan mothers

The aim of this study was to investigate the association between dental caries index among 12-year-old schoolchildren and individual and contextual factors related to the schools in the city of Goiânia, Goiás, Brazil. A cross-sectional study was carried out with 2,075 schoolchildren using the 2010 National Survey of Oral Health methodology. The dependent variable was the decayed, missing, and filled teeth (DMFT) index and the independent variables were individual (sex, race, and maternal education) and contextual ones (type of school, health district, and the presence of oral programs). Multilevel analysis and log-linear negative binominal regression were performed, considering the complex sampling design. Mean DMFT index was 1.51. Female students, whose mothers had lower schooling, those attending public schools, located in districts with the worst socioeconomic indicators, and covered by the Family Health Strategy had higher caries levels. The dental caries index was low and associated with the schoolchildren sociodemographic characteristics and factors related to the schools, showing inequalities in distribution.

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.
