    Notes: Objective: This study compared the preventive oral health behaviors of African-Americans and whites. Methods: Face-to-face interviews were conducted with a probability sample of 384 African-American and 358 white adults living in the greater Detroit area. Questions focused on brushing, flossing, and dental visits. Results: More than 95 percent of both groups reported brushing daily; however, whites were more likely to brush all teeth, including parts that do not show. Frequency of flossing did not differ between groups. African-Americans, however, were less likely to floss all of their teeth. Whites were more likely than African-Americans to get dental check-ups at least once a year and much less likely to indicate they had never had a dental check-up. African-Americans tended to have less education and lower family income than whites and were more likely than whites to have Medicaid. Race differences in brushing thoroughness and annual check-ups were greatly reduced when income, education, and insurance were controlled statistically. Conclusion: African-Americans are less likely than whites to brush thoroughly, floss thoroughly, and get dental check-ups. These differences are partly traceable to differences in socioeconomic status and access to professional oral health care.

    Notes: Objectives: The goals of this investigation were (1) to evaluate the Oral Health Status Index in relation to demographic characteristics, socioeconomic status, and preventive behaviors of an adult population; and (2) to understand how individual index components performed as indicators of oral health status compared to the composite index. Methods: The Oral Health Status Index (OHSI) was used on a probability sample of adults, aged 18–93 years, living in the Detroit tricounty area. Data were collected on 509 subjects via in-home dental examinations. Bivariate and multivariate analyses were used to compare the OHSI and its components, including decayed, missing, and replaced teeth, free ends, and moderate and severe periodontal disease measures. Results: The mean OHSI score for subjects was 77.3 (se=1.83) with a range of -8.0 to 100.0. In regression analyses, OHSI scores were positively correlated with subjects' education level, self-rated oral health scores, and frequency of dental checkups and negatively correlated with age, nonwhite race, and smoking. Of the index components, missing teeth performed well as an indicator of oral health status. Missing teeth were positively correlated with age, nonwhite race, and smoking and negatively correlated with education level, self-rated oral health, and use of Medicaid. About 53 percent of variance in OHSI scores was explained by the multivariate models, compared to 46 percent for missing teeth. Conclusions: Choosing an indicator of oral health status likely will depend upon the characteristics of the population to be studied. As a composite measure of oral health status, the OHSI performed acceptably; however, missing teeth, an index component, also worked well. Continued evaluation of the OHSI is warranted.

    Notes: Approximations commonly used to relate memory functions to time correlation functions governed by Newtonian dynamics are shown to be incorrect for strongly inhomogeneous systems. An exact expression for the space dependent diffusion coefficient is given in terms of time correlation functions whose dynamics are governed by Newton's equations. The resulting expression is evaluated using both the Bhatnagar–Gross–Krook kinetic equation and the Fokker–Planck equation to calculate the required time correlation functions for a system containing a specularly reflecting wall and for a system having a harmonic potential. For inhomogeneous systems, the memory function may not be approximated by the corresponding time correlation function. In addition, certain velocity correlations near a specularly reflecting wall are shown to contain a t−1/2 long time tail and a kinetic boundary layer whose thickness grows as t1/2; these features are absent from the memory function.

    Notes: The electrical double layer is studied using a cluster perturbation theory which incorporates the effect of images and fluctuations due to ion correlations. These equations are solved numerically and ion density profiles are determined for a wide range of surface charge and dielectric discontinuity. Two choices of the perturbation potential, corresponding to either the total electrostatic interaction or the polarization energy, are examined for a 1–1 electrolyte. Both theories exhibit excellent agreement with Monte Carlo results at low surface charge density and electrolyte concentration, but as the surface charge is increased for any dielectric discontinuity, the former theory overestimates the role of fluctuations, while the latter theory does better for intermediate values of the wall charge.

    Notes: A correlation function expression for the zero wave vector and frequency diffusion permeabilities for membranes having multiple potential barriers is derived for systems linearly displaced from equilibrium. The calculation of these correlation functions is discussed within the context of projection operator theory, and the resulting theory is applied to a model membrane system containing pores similar to those formed by gramicidin A. Stochastic simulations are performed using the BGK model and position dependent diffusion constants are obtained for Na+, Li+, and Rb+ at 300 K. The permeability can be computed from short-time dynamical information, although some commonly made approximations on memory functions are found to be incorrect.

    Notes: A classical electrodynamic near field calculation for the interaction of a Drude oscillator molecular dipole with a rough metal surface is presented. Effects of electromagnetic coupling between surface bumps (assumed to be prolate hemispheroids) and the bulk metal are included. Fluorescence lifetimes are found to be two to four orders of magnitude smaller than those predicted for a flat plane in calculations on silver, and for sufficiently short distances, an avoided crossing splitting is predicted.

    Notes: Abstract Current recommendations for periodontal health maintenance emphasize toothbrushing, flossing and periodic dental checkups. The purposes of this study were to examine (1) the effects of these practices on periodontal health and (2) the relationships of demographic and socioeconomic variables with these behaviors and with periodontal health. Adults (n= 319) in the Detroit, Michigan tri-county area were asked how frequently they performed the 3 preventive behaviors. Levels of plaque, gingivitis, calculus, and periodontal attachment were then assessed during in-home dental examinations. There were no statistically significant differences in these health measures between those with acceptable and unacceptable brushing behavior. About 20% of the subjects reported acceptable flossing behavior, and these individuals had significantly less plaque and calculus than other participants. Over 3/4 of subjects reported having a dental checkup at least 1 × a year, and these persons were found to have significantly less plaque, gingivitis, and calculus compared to less frequent attenders. Acceptable brushing behavior was not associated with any particular demographic or socio-economic characteristic, while differences in acceptable flossing behavior were found among age groups. Frequencies of yearly dental checkups varied significantly within every demographic and socioeconomic characteristic.

    Notes: Objectives: This investigation examined current practices of brushing, flossing, and periodic dental visits and their association with periodontal health status. Methods: Data were collected using face-to-face interviews and 40-minute in-home dental examinations with a probability sample of adults 18 years of age or older, having at least one tooth, and living in housing units in the Detroit tricounty area. Complete examinations were performed on 319 individuals. Results: On average, subjects reported brushing their teeth about twice a day. About one-third of the population reported flossing at least once a day. Loss of periodontal attachment was related to frequency of brushing while subjects who exhibited acceptable flossing ability had less plaque and calculus, shallower pocket depths, and less attachment loss. Subjects reporting a periodic dental visit at least once a year had less plaque, gingivitis, and calculus than subjects reporting less frequent visits. In regression analyses, brushing thoroughness, flossing ability and frequency, and dental visit frequency were predictors of lower plaque, gingivitis, and calculus scores. In turn, these scores were predictors of shallower pocket depths and less attachment loss. Conclusions: Brushing, flossing, and periodic dental visits were correlated with better periodontal health. The behaviors appeared to be indirectly related to pocket depth and attachment loss through their associations with plaque, gingivitis, and calculus levels.

    Notes: A survey was conducted to identify (a) factors that influence preventive dental behaviors and (b) target groups for interventions. Data were collected in face-to-face interviews with a probability sample of 662 dentate adults living in the Detroit tricounty area. The interviews included questions about demographic and socioeconomic variables and about three preventive behaviors: brushing, flossing, and preventive dental visits. All behaviors were positively associated with socioeconomic status. Females were more likely than males to perform each of the behaviors at the recommended frequency. The behaviors were only weakly associated with age. Whites were more likely than nonwhites to make regular dental visits, but frequency of brushing and flossing did not vary substantially across racial groups. The impact of race on frequency of dental visits was reduced when socioeconomic status was statistically controlled. Findings suggest that socioeconomic status, race, and sex remain important considerations when planning dental health education or other interventions.
