Initial Caries

Survival analyses have been used to overcome some of the limitations encountered with other statistical analyses. Although extended Cox hazard modeling with time-dependent variables has been utilized in several medical studies, it has never been utilized in assessing the complex relationship between mutans streptococci (MS) acquisition (time-dependent covariate) and time to having dental caries (outcome). This study involved secondary analyses of data from a prospective study conducted at the University of Alabama at Birmingham. Low socioeconomic status, African-American preschool children from Perry County, AL, USA (n = 95) had dental examinations at age 1 year and annually thereafter until age 6 years by three calibrated dentists. Salivary MS tests were done at ages 1, 1.5, 2, 2.5, 3, and 4 years. The patterns of and relationship between initial MS detection (time-dependent covariate) and dental caries experience occurrence were assessed, using extended Cox hazard modeling. The median time without MS acquisition (50% of the children not having positive MS test) was 2 years. Approximately 79% of the children had positive salivary MS tests by the age of 4 years. The median caries experience survival (50% of the children not having dental caries) was 4 years. During the follow-up period, 65 of the children (68.4%) had their initial primary caries experience. Results of the extended Cox hazard modeling showed a significant overall/global relationship between initial caries experience event at any given time during the follow-up period and having a positive salivary MS test at any time during the follow-up period (hazard ratio = 2.25, 95% CI 1.06-4.75). In conclusion, the extended Cox modeling was used for the first time and its results showed a significant global/overall relationship between MS acquisition and dental caries. Further research using causal mediation analysis with survival data is necessary, where the mediator “presence of MS” is treated as a time-dependent variable.

Permanent first molars are the most vulnerable teeth to dental caries. This study aimed to assess the association among the eruption stage of permanent first molars, demographic, socio-economic, tooth brushing behaviors and fluoride used among 6 - 8 years old schoolchildren of Tessaban Primary School in Hat Yai Municipality. Cross-sectional data on eruption stage of permanent first molars, demographic, socio-economic, tooth brushing behavior and fluoride used were assembled from 346 children-caretaker pairs using structured-questionnaire. Caries status was clinically examined using modified criteria from WHO. Fixed effect random intercept logistic regression was used to estimate the magnitude independent association between variables and caries status based on variability within-subject. The prevalence of dental caries in permanent first molars was 43.6 %, while the caries experience indexed as Decayed, Missing, and Filling Teeth (DMFT) was 1.00±1.36. Children who brush irregularly at night, share tooth brush among family member and have deciduous caries significantly inclined to have higher caries in the permanent first molars than those who did not. These findings should be noticed to take appropriate treatment and preventive measures in this age group.

Childhood Caries

The goals of this cross-sectional study were to characterize and compare demographic, behavioral, and environmental factors potentially associated with early childhood caries (ECC) and to assess salivary levels of mutans streptococci (MS) and lactobacilli (LB) in underserved, predominantly Hispanic children. One hundred forty-six children aged 3 to 55 months with a range of caries experience were identified and examined. ECC was primarily associated with the presence of MS and lack of access to dental care. Salivary MS levels among young children with ECC were higher than would be expected in a dentally healthy population, but lower than levels reported among older children at high risk for caries.After adjustment for age, children with log10 MS ≥ 3.0 or log10 LB ≥ 1.5 were about five times as likely (OR=4.9, 95%CI=2.0,12.0) to have ECC than those with lower bacterial levels. This study demonstrated a significant association between relatively low cariogenic bacterial levels and dental caries in infants and toddlers. Antibiotic use, exposure to lead, and anemia were not significantly associated with the number of decayed and filled surfaces or decayed and filled teeth. ECC correlated significantly with child's age and lack of dental insurance of the children, as well as inversely with both family income and the educational level of the mother of the child.

Root Surfaces

Dental plaque was obtained from one or two sound root surfaces of subjects with different degrees of root-surface caries experience. From subjects with root-surface caries, plaque samples were also obtained from either one incipient or one more advanced lesion. Proportions of the total flora were determined for total streptococci and different streptococcal species, total and different Actinomyces species, and lactobacilli. A sample of saliva was obtained from about one-third of the subjects for determination of the concentrations of mutans streptococci and lactobacilli. The main observations were: (1) Subjects without root-surface caries or restorations (group I), as compared with subjects with root-surface caries with or without restorations (group II), were characterized by having a lower prevalence and proportion of mutans streptococci and a higher prevalence and proportion of A. naeslundii in plaque on sound root surfaces; (2) subjects in group I also tended to have a lower salivary concentration of mutans streptococci and lactobacilli than subjects in group II; (3) dental plaque on sound surfaces in group II subjects contained a lower proportion of mutans streptococci than plaque associated with incipient or advanced lesions; and (4) the prevalence and proportion of lactobacilli in plaque associated with sound as well as carious root surfaces were very low. The data reinforce findings from other studies and indicate that, as for coronal caries, the plaque and saliva populations of mutans streptococci specifically are correlated positively with the presence of root-surface caries.

Childhood Caries

The relationship between dental caries and mutans streptococci (ms) in children and their mothers is a key factor in the prevention of early childhood caries. Changes in early childhood caries over time in Mexican children have not been well documented. Objective: to compare the dental caries indices and presence of ms in 3- to 5-year-old children and their mothers in two surveys, the first one carried out in 1996 and the second one in 2007. Study design: cross-sectional study. Results: The first survey included 102 mother-child dyads and the second 103. Dental caries index dmfs was 7.17 (± 10.9) and 4.58 (± 7.1) in the first and second survey, respectively (p<0.05). Ms levels were higher in 1996 than in 2007 (p<0.001). The prevalence of Severe Early Childhood Caries (SECC) was 42.2% and 34.95% in first and second surveys, respectively,(p>0.05). Children with SECC showed higher counts of ms than children without this condition. A high caries index in mothers was associated with higher caries experience in their children. Conclusion: the compassions of the surveys indicated a decline in dental caries indices over an 11-year period. High caries experience in the mother had a negative impact on the oral condition of the child.
