HAFFAJEE2, 1 New York University, USA, 2 The Forsyth Institute, Boston, MA, USA Objective: To assess the effect of ethnicity/race on the progression of destructive periodontal diseases, a longitudinal study of 3 urban minority populations was conducted to determine whether rates of disease progression and clinical and demographic risk factors for disease progression varied among three ethnic/racial groups. Methods: Subjects were recruited through in-house screenings by the Northeast Regional Research Center for Minority Oral Health and patient admissions at New York University College of Dentistry. The study population consisted of 184 subjects, ages 19-60 (mean 33.9, SD 9.0), of whom 53 were Asian-, 69 were African- and 62 were Hispanic-American. Clinical indices including pocket depth, attachment level, gingival erythema, bleeding upon probing, suppuration and supragingival plaque were recorded at six sites per tooth. Disease progression was defined as a > 2 mm loss of attachment 2 months post-baseline. A demographic and behavioral questionnaire was also administered at baseline. Results: The African-American group had the greatest number of sites per subject losing > 2 mm. of attachment compared with the two other ethnic/racial groups, though this did not attain statistical significance. The variables associated with subsequent attachment loss for the entire population were age, male gender, increased levels of plaque, erythema, bleeding upon probing, suppuration, attachment loss, pocketing, and belonging to the “unskilled” occupational group. A prognostic model was developed to relate the clinical and demographic variables with subsequent attachment loss using multivariate stepwise regression analysis. The model indicated that prior attachment loss, gingival erythema, suppuration, being a current smoker and belonging to the “unskilled” occupational group conferred high risk of > 1 site of attachment loss of > 2 mm. Conclusion: These findings suggest that variables associated with ethnicity/race, such as occupational status, may be responsible for the disparity observed in destructive periodontal disease progression in these populations.
