Study Results


"Isolation Techniques Used When Performing Root Canal Treatment"

 View the full questionnaire.

Supplemental tables 1-6 include the distribution of the characteristics of eligible practitioners and their association with participation in the study; practitioners by tooth type for which they do root canal treatment; type and frequency of isolation method used; practitioner/practice characteristics by rubber dam use; stratified by frequency whether they perform root canal treatment on molars; as associations with using a rubber dam all the time.

Supplemental tables A1-A2 include frequency distribution for each attitude question item and a multivariable logistic regression of dentists' attitudes about rubber dam use and whether or not they use a rubber dam 90% of the time or more often.

Supplemental table 3A includes logistic regressions of practitioner characteristics associated with use of endodontic methods characterized as 'inappropriate' by the endodontist authors.

"Cracked Tooth Registry"

This is an observational study examining the natural history of posterior cracked teeth, in which initial screening, patient enrollment, informed consent, initial data collection, and treatment (if indicated) are completed at baseline. Subsequent annual recalls are completed and follow-up data recorded. Treatment on a study tooth is always documented.

At the initial baseline visit, the following forms were used: patient characteristics, baseline: exam and treatment form, and reference worksheet.

For recall visits, the reference worksheet and appropriate (year 1, 2, 3) annual follow-up exam and treatment forms are completed.

For treatment accomplished other than at baseline or annual recalls, the treatment visit form is used.

If a patient will no longer participate in the study, a discontinuation form is filled out.

If a patient moves from the study practice, and is unwilling or unable to see a network dentist to continue data collection, a patient telephone interview guide and form will be used to obtain information. 


"Development of a Patient-Based Provider Intervention for Early Caries Management"

In Phase I, practitioners were interviewed about their opinions on non-invasive caries treatment and patients' preferences by using an interview script .

Non-invasive treatment patients were offered the opportunity to provide feedback during a telephone interview

Based on information collected from patients and providers in Phase I, we designed a patient education brochure and "patient satisfaction with treatment for early caries" survey in Phase II. These two forms were handed to the patients who participated in the Phase III study.

Each practitioner kept track of how many patients received non-invasive treatment for early caries during the data collection period, along with how many of these agreed to participate in the study.

Before the final data collection in Phase III, practitioners participated in an individual training session

For each patient, practitioners completed a data collection form and a caries risk assessment form

Study Highlights:  Dental Practice-Based Research Networks

Read about the the following study highlights from the Practice-Based Research Network:

  • Assessing Outcomes of Cracked Teeth
  • Remineralization of White Spot Lesions after Removal of Orthodontic Brackets
  • Single Tooth Endodontic and Restorative Treatment Outcomes:  PEARL Interim Findings

“Dental Tobacco Control Randomized Clinical Trial”

Several instruments were used for data collection in this study. Initially, the patients at each dental practice were queried about whether the dentist asked or advised about tobacco use, the patient’s smoking status and willingness to participate in a telephone interview

Each dental practice completed a baseline survey about the demographics and characteristics of its practice.

After participating in the web intervention directed at increasing tobacco control practices in dentistry, the practices were re-assessed.

At the end of the study, patients who agreed to participate were contacted about the status of their tobacco use and attempts to quit.

Dental practices completed a final survey that assessed how their dental practice changed tobacco cessation practices.

"Reasons for Replacement or Repair of Dental Restorations"

Main data collection form

Each practitioner kept track of how many eligible patients presented for treatment during the data collection period, along with how many of these agreed to participate in the study. 

Each practice kept track of the names of each participant because the network tracked these restorations longitudinally. This information was kept at the dental practice and at the regional office, but was not passed on to the Coordinating Center.

"Hygienists' Internet Tobacco Cessation Randomized Clinical Trial"

To determine study eligibility practices returned the interest survey.

Each dental practice completed a baseline survey on the demographics and characteristics of its practice.

After randomization, providers completed a qualitative survey and an online survey.

Patients who were referred and logged-on to the patient intervention site completed an online survey.

The dental practices completed a final survey to reassess their tobacco control practices and the patients completed a follow-up survey to assess their smoking status six months after registering on the quit smoking website.


"Blood Glucose Testing in Dental Practice"

This study used several data forms. The first one was the “Screening and Testing” form, which provided patient information and risk for diabetes mellitus.

If the patient qualified and agreed, this form also collected the glucose test result. Another form was a questionnaire answered by the patient.

Participants received a Physician Referral Letter and an information brochure about diabetes from the American Diabetes Association.

We also used a questionnaire completed by the practice’s dentist and staff ; it provided insights regarding the feasibility of and possible barriers to glucose testing in dental practice. Each Regional Coordinator also conducted an end-of-study interview of the participating practitioners. Finally, we used a “Consecutive Patient Log” and a “Master Participant List”.

Practitioner completed a data form before beginning the root canal, and a different one after obturation.

Each practitioner also kept track of how many eligible patients presented for treatment during the data collection period, along with how many of these agreed to participate in the study.

Patients who were receiving root canal treatment completed a questionnaire immediately before treatment , another one immediately after treatment, and another form one week after treatment.

Patients also completed a form with contact information. When the root canal treatment required more than one visit, comparable forms were again completed by the dentist practitioner and the patient.

An additional form was completed by the dentist regarding pain and anxiety management for the treated tooth.

"Diagnoses for Persistent Dentoalveolar Pain following Root Canal Therapy"

Patients were followed for six months after they completed their root canal treatment. This nested case-control study brings those patients who were still reporting pain at 6 months, as well as their age-, gender- and tooth-matched controls, into the clinic to be evaluated by endodontic and orofacial pain experts. The primary goal of this study is to determine the proportion of patients with pain who would best be managed with typical dental care compared to those who have a non-odontogenic source for their pain, so that treatment directed at the etiology of their pain can occur.

Questionnaires completed by the patients.

Forms completed by the practitioner.

This study was a pre-planned re-administration of the PIRG questionnaire, with the objective of quantifying any change since the first administration. It was also administered to other practitioners in the CONDOR group. The CONDOR group - the Collaboration on Networked Dental and Oral Research - comprised three dental practice-based research networks funded by the National Institute of Dental and Craniofacial Research (NIDCR). These networks were DPBRN, PEARL, and NWPRECEDENT.
