Behavioral risk indicators of attachment loss in adult Floridians.

This study investigated behavioral and sociodemographic risk indicators of attachment loss (AL) at baseline in subjects of the Florida Dental Care Study: 873 subjects with at least 1 tooth, and who were 45+ years or older, participated for an in-person interview and dental examination; 761 subjects were probed for AL. Calibrated examiners used a modified NIDR protocol from the 1985-86 Survey of US Employed Adults and Seniors. Results were weighted to reflect actual population proportions. 92% of subjects had at least 1 site of 4+ mm AL, and 35% had at least 1 severe site (7+ mm AL). In a single multivariate regression, not having a recent dental check-up, not using dental floss, being a current smoker, and being diabetic were significantly associated with a higher probability of having 1 or more severe sites. Blacks were less likely than whites to be regular users of dental care, use dental floss, and be non-smokers. Similar findings were found for low income adults and rural residents. Risk groups (low income, blacks, rural residents) were more likely to present with modifiable risk indicators for AL, suggesting the need for targeted interventions.

Coronal caries, root fragments, and restoration and cusp fractures in US adults.

The Florida Dental Care Study is a longitudinal study of changes in oral health that included at baseline 873 subjects (Ss) who had at least 1 tooth, were 45 years or older, and participated for an interview and examination. Forty-five percent of Ss had active coronal caries; 94% of the coronal carious surfaces were primary decay, and only 6% were secondary/recurrent. Ten percent of Ss had 1 or more root fragments, 16% of Ss had 1 or more teeth with restoration fractures, and 14% of Ss had 1 or more teeth with cusp fractures. Blacks, poor persons, and irregular attenders had more caries, root fragments, and cusp fractures, even though they had significantly fewer teeth. Blacks, poor persons, and irregular attenders were not at increased risk for restoration fractures, probably because fractures were associated with dental care use. These findings regarding caries and restorative treatment needs are consistent with a substantial burden in adult high-risk groups, and are relevant for dental primary health care policy.

Root caries and root defects in urban and rural adults: the Florida Dental Care Study.

As part of the Florida Dental Care Study--a longitudinal study of risk factors for changes in dental health--the authors examined and interviewed 873 adults aged 45 years and older. During the examination, clinicians noted the number of teeth present and the participant's dental condition, including presence of root caries and fillings or noncarious defects on the roots. The interview was conducted to collect demographic and other information such as the adults' perceptions about dental care and their perceptions about their own dental health. The authors found that men, African-Americans, adults living in rural areas and those living in poverty were significantly more likely to have root caries than other participants. The data reported in this article will serve as baseline information for subsequent research.

Visual and profilometric wear measurements.

Wear of composites can be estimated by the degree of marginal discrepancy between the prepared cavity wall and the occlusal margins of composites. Such evaluations are done on casts by comparing and rating the marginal discrepancy with those on standard casts. We analyzed the reliability of this technique on metal and stone specimens. These specimens contained grooves of different width and depth. For the visual comparison we used stone casts of machined standards of known groove depth. We measured the depths of the metal specimens with a profilometer and made stone casts of these original specimens. Using the stone casts of the standards, five dentists estimated the unknown groove depths on the remaining stone casts. These estimates were done under standardized conditions and repeated by each dentist on five different occasions. The results showed that visual depth evaluations of die stone specimens underestimated the depths when compared with the values measured with a profilometer on the original metal models. One investigator gave significantly different (p less than 0.05) groove depth estimates at different occasions.

Analysis of disagreement in the evaluation of clinical products.

This paper reports an analysis of factors that reduce agreement in clinical evaluation. Four instructors representing different restorative departments met regularly over a four-month period to study the evaluation process. Each participant selected a task from his discipline, identified critical errors made in performing the task, produced these errors in models and extracted teeth, and developed criteria and checklists to aid in categorizing and counting the errors. In weekly sessions the models were evaluated, and judgments were compared. Factors that reduced agreement were identified, discussed, and listed. In some sessions ongoing evaluation was reported orally, tape-recorded, and analyzed to elucidate the underlying mental processes. Analysis indicated that agreement was reduced by 16 factors, including unclear rules, the faculty member's memory, unstandardized aids to judgment, inconsistent observational methods, differences in ability, and differing tendencies to leniency.
