About this study

The study will determine whether clinicians who use a diagnostic device treat suspicious occlusal carious lesions (SOCL) surgically more often, with the same frequency, or less frequently, than dentists not relying on a diagnostic device. The study will also determine -- among those SOCLs that are opened -- whether the proportion of lesions that extend into the dentin when dentists are using a diagnostic device is more than, the same, or less than when no device is used.

Read the detailed description

The overall objectives of this study is to assess the contributions of diagnostic devices in clinicians' decision-making processes surrounding suspicious occlusal carious lesions (SOCL), an assessment that has not yet been attempted, despite the growing popularity of these devices. SOCLs can be defined as occlusal surface areas where visual, tactile, and radiographic signs are insufficient to definitively diagnose caries but where some of these signs are present.This study examines the use of two diagnostic devices on dental practitioners' identification and treatment of SOCLs.

During a four-week pre-intervention period, 90 clinicians will collect and record descriptive and treatment information for the SOCLs they identify. Clinicians will then be randomized into one of 3 study arms: no diagnostic device, DIAGNOdent®, and Spectra®, and will collect and record similar information as the pre-intervention period for another six weeks, enrolling an additional 20 SOCLs. They will also complete diagnostic vignettes at the beginning and end of the study, as well as a post-study questionnaire on the utility of the devices, if assigned to a device arm. Analyses will examine differences in proportion of SOCLs treated surgically in the groups with and without the diagnostic device; and, for those treated surgically, differences in the proportions of SOCLs with extension into dentin. Differences in pre- and post-study responses on the vignettes will suggest which components of the decision-making process involved in SOCL identification and management have been modified by use of the diagnostic devices.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Spectra DeviceDevice

    Spectra Caries detection device is used for study data collection recording the results of the dental examination and recording results of dental treatment.

  • DIAGNOdentDevice

    DIAGNOdent Caries detection device is used for study data collection recording the results of the dental examination and recording results of dental treatment.

Study groupRoleWhat they receive
No Device CliniciansNo interventionThe clinicians will not receive any additional training.
Spectra Device CliniciansExperimentalThe clinicians in the Spectra Device Arm will be trained to the device according to the manufacturers' usual care for training. The training will consist of viewing the manufacturer's instructions for the device. Training will also consist of clinicians familiarizing themselves with the device through unsupervised clinical use with patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Lesions That Received Invasive Treatment and the Number of Lesions Receiving Invasive Treatment That Extended Into Dentin

    There was one lesion/patient.

    Measured: Pre-intervention and post-intervention (one day visit)

Secondary outcomes (2)
  1. Number of Clinicians in Likelihood of Surgically Treating Lesions in Online Vignettes That Display Two Levels of Five Cues (Color, Surface Smoothness, Surface Luster, Caries Risk, and Device Reading (if Applicable) in Post-intervention

    Clinicians' likelihood of treating surgical lesions depicted with brown verses black, smooth verses rough, shiny verses matte, in patients with high verses low caries risk, by post-intervention phases. The outcome measure will be to see what cues were used or treatment decisions in the post-intervention phase. Please note that more than one cue could be chosen, so values may add up to more than 100 percent. Participants in the no device group did not receive a device reading cue.

    Measured: Post-intervention (dentists completed the vignettes one time)

  2. Number of Clinicians in Likelihood of Surgically Treating Lesions in Online Vignettes That Display Two Levels of Four Cues (Color, Surface Smoothness, Surface Luster, and Caries Risk) in Pre-intervention

    Clinicians' likelihood of treating surgical lesions depicted with brown verses black, smooth verses rough, shiny verses matte, in patients with high verses low caries risk, by post-intervention phases. The outcome measure will be to see what cues were used or treatment decisions in the pre-intervention phase. Please note that more than one cue could be chosen, so values may add to more than 100 percent of participants.

    Measured: Pre-intervention (dentists completed the vignettes one time)

Questions about this trial

What is this clinical trial studying?

A study testing Spectra Device and DIAGNOdent in people with Dental Caries, run by The National Dental Practice-Based Research Network at 6 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 21 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Apr 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Lesions That Received Invasive Treatment and the Number of Lesions Receiving Invasive Treatment That Extended Into Dentin (time frame: Pre-intervention and post-intervention (one day visit)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Apr 2019.
