CAMBRA - PBRN Caries Management By Risk Assessment In A Practice-Based Research Network

Overview

The goal of this project is to create a Practice Based Research Network with 30 researcher dentists calibrated on the administration of a caries risk assessment and the treatment modalities recommended based on the caries risk assessment results (Caries Management by Risk Assessment - CAMBRA), and to conduct a 2-year CAMBRA study in those dental offices. Participating dentists will be a mix of general practitioners and pediatric dentists selected from private practice, part time university faculty, large group practices, or community clinics. Participating practices will collect baseline data and patient progress and report on patient acceptance and compliance, and the effectiveness of treatment. The program's duration is anticipated to be approximately four years. Year one will be dedicated to program, protocol and evaluation design, and recruitment, selection and calibration of researcher dentists. Years two and three will be the research and data collection time period, and year four will be dedicated to evaluation.

The clinical part of the project will prove that CAMBRA principles can successfully be disseminated into everyday dental practices and that by applying the principles of Caries Management by Risk Assessment to subjects in those practices a major reduction in caries can be seen in the intervention group in comparison to the control group. At the end of the two year clinical part performed in the Practice Based Research Network data will show that the positive results of the first CAMBRA study achieved in the university setting at UCSF can also be accomplished in a dental practice setting to the benefit of patients. If CAMBRA can be successfully disseminated into dental practices dental care costs can significantly be reduced. The overall study objective is to build a Practice Based Research Network (PBRN) and to conduct in this setting a 2-year randomized, controlled, double blind clinical trial to provide clinical evidence that scientifically based caries risk assessment, in conjunction with aggressive preventive measures and conservative restorations will result in dramatically reduced further caries increment. If successful this study performed in a PBRN will provide substantial evidence for changing the practice of caries management. The planned study is a double blind practice-based clinical study. The California Dental Association Foundation will help to select up to 30 participating dentists. Practitioners will perform a Caries Management by Risk Assessment (CAMBRA) evaluation and will instruct and provide treatment suggestions for the study subjects according to the CAMBRA protocol. The hypothesis to be tested is that caries management based on caries-risk status (low, moderate or high) will significantly reduce the need for caries restorative treatment over two (plus) years compared to usual dental treatment in the practice based setting. The primary outcome measure will be caries increment. At the end of the two year clinical part performed in the Practice Based Research Network data will show that the positive results of the first CAMBRA study achieved in the university setting at UCSF can also be accomplished in a dental practice setting to the benefit of patients. If CAMBRA can be successfully implemented into dental practices in the future dental care costs can significantly be reduced.
