Suspicious Occlusal Caries

Brief summary

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

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.

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.

Pre-assignment details

The study had a pre-intervention phase, 108 clinicians (HS trained, consented, and met eligibility criterion) and 1500 patients enrolled. 85 clinicians met the enrollment threshold and were randomized.1500 patients were in the post-intervention phase.The pre- and post patients were not the same so the number analyzed for each group varies.

The practitioners 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 practitioners familiarizing themselves with the device through unsupervised clinical use with patients.
