Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

No Device Clinicians

The clinicians will not receive any additional training.

Group Type NO_INTERVENTION

No interventions assigned to this group

Spectra Device Clinicians

The 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.

Group Type EXPERIMENTAL

Spectra Device

Intervention Type DEVICE

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

DIAGNOdent Device Practitioners

The clinicians in the DIAGNOdent 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.

Group Type EXPERIMENTAL

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Practitioner: In order to be eligible to participate in this study, an individual must meet all of the following criteria:

* Is enrolled in the National Dental Practice Based Research Network (National Dental PBRN);
* Has completed an Enrollment Questionnaire;
* Is a general or pediatric dentist who is licensed in the United States to treat patients and treats patients in the United States on a recurring basis;
* Is trained and certified in Human Subjects Protection Training;
* Has attended or viewed a National Dental PBRN orientation session or attended at least one annual regional meeting of practitioners or has attended a National Dental PBRN workshop at the International Association for Dental Research (IADR) or American Association for Dental Research (AADR).
* Performs restorative dentistry routinely in their practices as reported on the enrollment questionnaire;
* Has no clinical experience (no history of routine use in practice within the past one year) with either of the devices being used in the study and declares no conflict of interest with the corporations that produce DIAGNOdent® and Spectra®; and
* Is able to complete the pre-and post-study vignettes online.

Practice: If a practitioner is in a practice where they share an operatory (including a hygiene chair) only 1 dentist can be recruited from that practice.

Patient: In order to be eligible to participate in this study, an individual with a SOCL must meet all of the following criteria:

* Willing to provide consent according to regionally approved procedures and/or obtain parent/legal guardian permission as applicable;
* Willing to comply with all study procedures; Is six years of age or older; and
* Has not participated in the study previously. Patients will be enrolled only once throughout the study (this includes the pre-intervention and intervention phases for the pilot study and full study).

Tooth: In order to be eligible to be included in this study, a tooth with a SOCL must meet all of the following criteria:

* Permanent tooth;
* No radiographic evidence of caries into dentin based on available radiographs;
* Caries into dentin is suspected due to roughness, surface opacities, or staining;
* No symptoms of sensitivity to sweets, cold, air, etc.;
* No restoration on the occlusal surface; and
* No sealant on occlusal surface.

Exclusion Criteria
