Clinical Trial Summary

The purpose of this study was to document the reasons for placing the first restoration ("filling") on a previously un-restored surface in a permanent ("adult") tooth.

Description:

The aims of this study were to (1) quantify DPBRN practitioner-investigators pre-operative and post-operative assessments of the depth of the caries lesion being treated; (2) quantify the prevalence of dental material types used to restore the first restoration in a permanent tooth surface; and (3) test the hypothesis that DPBRN practitioner investigators in the "Assessment of caries diagnosis and caries treatment" study who stated that they wait until the caries lesions reach dentin before they place the first restoration are in fact more likely in this study to do restoration in teeth that have caries reaching into dentin.

The aims were met by enrolling 230 DPBRN practitioner-investigators in the "Reasons for placing the first restoration on permanent tooth surfaces" study, each of whom recorded information about approximately 50 consecutive restorations that they placed on unrestored surfaces. This study about restorative treatment received by patients provided the opportunity to record the variations in the treatment provided, and also provided a basis for subsequent future studies to investigate how defects on fillings develop over time. These results will also be related to the findings from "Assessment of caries diagnosis and caries treatment" study where practitioners outlined how they detected dental decay, the stage at which the decay was treated by placing fillings, and how they rely on preventive measures to stop the decay process without placing fillings.

Eligibility

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 unrestored 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.

Exclusion Criteria:
