Studies for which we are currently recruiting:
Decision Aids for the Management of Suspicious Occlusal Caries Lesions (SOCL)
The study examines the use of two diagnostic devices on dental practitioners’ identification and treatment of SOCLs. A total of 90 practitioners throughout the nation will collect and record descriptive and treatment information for 40 SOCLs (one lesion/patient), 20 during the pre-intervention period and 20 during the intervention period. Practitioners will be randomized into one of three arms: no diagnostic device, DIAGNOdent, and Spectra. They will also complete diagnostic vignettes at the beginning and end of each study, as well as a post-study questionnaire.
The primary objective of the study is to quantify the difference in proportion of SOCLs treated operatively when a diagnostic device is used compared to when one is not used, and to quantify the difference in proportion of SOCLs treated operatively that extend into dentin when a diagnostic device is used compared to when one is not used.
The secondary objectives of the study are:
- Identify the clinical characteristics of SOCLs that best predict caries that extend into dentin;
- Determine whether the principal factors used by participating practitioners in managing SOCLs change when a caries detecting device is employed; and
- Obtain practitioners’ assessments of the utility of the devices in their practices.
Management of Dentin Hypersensitivity
This is a prospective cohort study of patients with dentin hypersensitivity. The study population will consist of adult dental patients who have dentin hypersensitivity and the practitioners who provide treatment for this condition. Approximately 180 dentists across the nation will enroll 14 study patients, with an enrollment aim of 2,520 adult patients for the entire network.
The primary objective of the study is to gain a better understanding of the multiple treatments used to manage dentin hypersensitivity among US dental practitioners by characterizing methods of diagnosing dentin hypersensitivity in the practice setting, dentists’ selected treatment(s) of dentin hypersensitivity, and patient-reported pain outcomes over time.
The secondary objectives of the study are to explore patient-, practitioner-, practice-, and tooth-level characteristics that may contribute to practitioners’ selected treatment(s) and approach(es) to care and to characterize patients’ satisfaction with the received treatment of dentin hypersensitivity.
Cracked Tooth Registry
This will be a prospective, observational 4-year cohort study of both symptomatic and asymptomatic cracked teeth in 3,000 patients of ages 19-85 from 150-300 National Dental PBRN practices. Subjects will receive patient-, tooth- and crack-level assessments of a cracked tooth at baseline and follow-up visits over the subsequent four years.
The primary objective of the study is to identify patient-, tooth-, and crack- level characteristics associated with initial tooth symptom status, and to determine, over a four-year follow-up period, the associations of these multi-level factors with changes (tooth “failure”) that may occur in an initially symptomatic or asymptomatic cracked tooth. Changes in the study tooth over time—outcomes that define the development of tooth “failure”– include crack progression, sign/symptom development, need for restorative dentistry, endodontic therapy or tooth extraction, development of periradicular lucency and loss of pulp vitality.
It is anticipated that many teeth will require treatment over the course of the study period. Therefore, secondary objectives of the study are to:
- Identify multi-level (practice-, practitioner-, patient-, tooth-, and crack- level) factors associated with treatment recommendations for asymptomatic and symptomatic teeth provided by practitioners across the US;
- Identify associations between crack characteristics and time-to-treatment rendered during the four-year follow-up period;
- Determine, among treated cracked teeth, associations between the external and internal crack characteristics, which will include externally detectable characteristics and internal characteristics that are observed during invasive treatment of the tooth.
- Evaluate outcomes of various treatments rendered on cracked teeth by determining associations between treatment rendered and time to tooth failure after treatment has been rendered on cracked teeth during the four-year follow-up period. These tooth outcomes include crack progression, sign/symptom development, and further recommended treatment of the tooth, development of periradicular lucency and loss of pulp vitality.
