Abstract

OBJECTIVES (1) quantify 12-month failures of restorations that were repaired or replaced at baseline; (2) test the hypothesis that no significant differences exist in failure percentages between repaired and replaced restorations after 12 months; (3) test the hypothesis that certain dentist’s, patient’s and restoration’s characteristics are significantly associated with the incidence of restoration failure. METHODS This prospective cohort study included dentists in the National Dental Practice-Based Research Network. Dentists recorded data for 50 or more consecutive defective restorations. The restorations that were either repaired or replaced were recalled after 12 months and characterized for developing defects. RESULTS 195 dentists recorded data on 5,889 restorations. 378 restorations required additional treatment (74 repaired, 171 replaced, 84 teeth received endodontic treatment, and 49 were extracted). Multivariable logistic regression analysis indicated that additional treatment was more likely to occur if the original restoration had been repaired (7%) compared to replaced (5%)(OR = 1.6, p < .001; 95% CI: 1.2, 2.1), if a molar tooth was restored (7%) compared to pre-molar or anterior teeth (5%, 6% respectively)(OR = 1.4, p = .010; 95% CI: 1.1, 1.7), and if the primary reason was a fracture (8%) compared to other reasons (6%)(OR = 1.3, p = .033; 95% CI: 1.1, 1.6). CONCLUSION An additional treatment was more likely to occur within the first year if the original restoration had been repaired (7%) compared to being replaced (5%). However, repaired restorations were less likely to need an aggressive treatment (replacement, endodontic treatment, or extraction) than replaced restorations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
