About this study

The aims of this study were to (1) quantify the prevalence of reason(s) for replacing existing restorations in DPBRN practices; (2) quantify the percentages and types of restorative materials of failed restorations that are being replaced in DPBRN practices; (3) quantify the percentages and types of restorative materials used to replace or repair failed restorations in DPBRN practices; and (4) test the hypothesis that DPBRN practitioner-investigators who reported in a previous study that they treat enamel lesions operatively are more likely in actual patients as in this study to replace entire restorations rather than do repairs and are more likely to report the clinical diagnosis of secondary caries as a reason for replacement.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • participants directly involved in this study were patients who sought dental treatment in the practitioner-investigators practices
  • any tooth surface that was previously restored was eligible for this study, provided that it was on a permanent ("adult") tooth. This means that permanent first molars were eligible, which typically erupt at about age 6 years. This means that persons age 6 and older were enrolled in the study and there was no upper age limit.
