“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 (click here). Each dental practice completed a baseline survey about the demographics and characteristics of its practice (click here). After participating in the web intervention directed at increasing tobacco control practices in dentistry, the practices were re-assessed (click here). At the end of the study, patients who agreed to participate were contacted about the status of their tobacco use and attempts to quit (click here). Dental practices completed a final survey that assessed how their dental practice changed tobacco cessation practices (click here).

"Development of a patient-based provider intervention for early caries management"

In Phase I, practitioner-investigators were interviewed about their opinions on non-invasive caries treatment and patients' preferences; the interview script can be viewed here. Next, non-invasive treatment patients were offered the opportunity to provide feedback during a telephone interview. The patient interview can be accessed here. Based on information collected from patients and providers in Phase I, we designed a patient education brochure (click here) and "patient satisfaction with treatment for early caries" survey (click here) in Phase II. These two forms were handed to the patients who participated in the Phase III study. Each practitioner-investigator 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. This form can be viewed by clicking here. Before the final data collection in Phase III, practitioner-investigators participated in an individual training session; the slides of the presentation may be found here. For each patient, practitioners completed a data collection form (click here) and a caries risk assessment form (click here). Each practice also kept track of the patients who presented with early caries and how many agreed to participate in the study. This form can be viewed by clicking here.

"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.
