Counts are the number of restorations, not the number of patients. Percentages are within rows for each patient characteristic. Of the 1,301 restorations reported in this study, data were collected on patient’s age from 1,300 restorations; 1,298 on gender; 1,256 on ethnicity; 1,227 on race; and 1,297 on insurance coverage. AAE: abrasion, abfraction, or erosion lesions; Others: developmental defects or hypoplasia, endodontically-treated teeth, or other unspecified reasons; Black: Black or African-American; Other race: American Indian/Alaska Native, Native Hawaiian/Pacific Islander and others.
P-values are based on chi-square tests, adjusted for the effects of multiple observations per dentist; *age group in years: p<0.0001 and *race: p=0.0246. The associations between other variables and reasons for restoration were not statistically significant.
