eighteen-month coronal caries incidence in north carolina older adults.in this longitudinal study of a random sample of north carolinians over the age of 65 and living in their homes, 325 blacks and 280 whites were examined and interviewed 18 months after baseline examinations. coronal caries incidence was greater among whites than blacks. the increment due to teeth becoming root fragments were similar for both races; however, there were more newly crowned teeth among whites. newly crowned surfaces were not used as part of the caries increment in logistic regressio ...19947909331
streptococcus mutans, lactobacilli, and caries experience in older adults.this study investigated salivary levels of streptococcus mutans, lactobacilli, and caries experience in a random sample of 448 black and 362 white older dentate adults living in north carolina. significant proportions of the participants had stimulated salivary flow rates less than 1.0 ml/min, salivary buffering capacity less than 4.0, s. mutans levels of 10(5) cfu/ml or more in stimulated whole saliva, or lactobacilli levels of 10(5) cfu/ml or more. each of these factor levels could be consider ...19921440133
the distribution and interrelationship of actinobacillus actinomycetemcomitans, porphyromonas gingivalis, prevotella intermedia, and bana scores among older adults.in a random sample of subgingival dental plaque samples from 375 blacks and 300 whites aged 65 and older, immunofluorescence assays for 3 target pathogens including actinobacillus actinomycetemcomitans, porphyromonas gingivalis, and prevotella intermedia, and bana enzyme analysis were carried out. blacks had significantly greater proportions of p. gingivalis and p. intermedia in their subgingival plaque and had significantly higher bana scores. these assay results were investigated for concordan ...19938381866
university of north carolina caries risk assessment study. iii. multiple factors in caries prevalence.the baseline caries experienced of approximately 5,000 children in south carolina and maine was used as the dependent variable in caries risk assessment analyses. clinical, microbiologic, and demographic factors served as independent variables in a multivariate relationship to caries through regression and discriminant function analyses. four factors--number of dental visits by the child in the past year, presence of white spot lesions, and both the urgency of need for restorative care and the f ...19911920265
models for coronal caries and root fragments in an elderly population.a random sample of 809 dentate, home-dwelling people 65 years of age or older participated in a study to determine the prevalence of dental diseases in the elderly. part of the study investigated the determinants of coronal caries and root fragments in these older adults. using a wide array of potentially explanatory variables available, logistic regression models were developed to identify relationships between these variables and coronal caries and root fragments. the variables with the most e ...19921468107
the university of north carolina caries risk assessment study: further developments in caries risk prediction.over 4000 first and fifth grade children from the areas surrounding aiken, south carolina, and portland, maine, participated in a 4-yr study to develop caries risk assessment models. the predictors used at baseline included detailed clinical examinations, salivary microbiological tests, and sociodemographic and dental behavior data. mean 3-yr caries increments in south carolina were twice those in maine. for the four risk assessment models (two grade cohorts at two sites) specificity values aver ...19921555390
three-year tooth loss among black and white older adults in north carolina.the distribution and determinants of tooth loss in older adults are poorly defined, especially in blacks, who have been underrepresented in previous studies. this study investigated, epidemiologically, the distribution and predictors of tooth loss in elder blacks and whites by following a random sample of older adults in north carolina for three years. it was hypothesized that blacks would be at greater risk of tooth loss and would have different risk factors for tooth loss. data from 263 blacks ...19957722064
the university of north carolina caries risk assessment study. i: rationale and content.this article presents the rationale and content of a current study that seeks to improve methods to identify children at high risk to dental caries. it summarizes the results of the development of a 12-factor, preliminary caries prediction model based on data derived from the national preventive demonstration program. despite data limitations, the model produced a sensitivity of .5 and specificity of .8 for four-year caries increment prediction in first- and fifth-grade children. data on a numbe ...19883184028
