Background: We describe a retrospective assessment of practitioner and patient recruitment strategies, patient retention strategies, and rates for five clinical studies conducted in the National Dental Practice-Based Research Network between 2012 and 2019, and practitioner and patient characteristics associated with retention.
Methods: Similar recruitment strategies were adopted in the studies. The characteristics of the practitioners and patients are described.
Objectives: This study was designed to: 1) evaluate and compare the evidence-practice gap (EPG) in minimal intervention dentistry (MID) in Japan and Brazil by measuring concordance between dentists' clinical practice and published evidence; and 2) identify dentists' factors associated with the EPG in both countries.
Methods: We performed a cross-sectional study using a web-delivered questionnaire among 136 Japanese and 110 Brazilian dentists. The questionnaire consisted of three questions concerning "restoration diagnosis and treatment," "deep caries diagnosis and treatment," and "caries risk assessment" regarding MID.
Objective: Quantify the survival of posterior composite restorations (PCR) placed during the study period in permanent teeth in United States (US) general dental community practices and factors predictive of that survival.
Methods: A retrospective cohort study was conducted utilizing de-identified electronic dental record (EDR) data of patients who received a PCR in 99 general dentistry practices in the National Dental Practice-Based Research Network (Network). The final analyzed data set included 700,885 PCRs from 200,988 patients.
Background: Despite advances in temporomandibular disorders' (TMDs) diagnosis, the diagnostic process continues to be problematic in non-specialist settings.
Objective: To complete a Delphi process to shorten the Diagnostic Criteria for TMD (DC/TMD) to a brief DC/TMD (bDC/TMD) for expedient clinical diagnosis and initial management.
Methods: An international Delphi panel was created with 23 clinicians representing major specialities, general dentistry and related fields.
Better understanding of dentists' decision-making about defective restorations is needed to close the evidence-practice gap (EPG). this study aimed to quantify the EPG about defective restorations and identify dentist factors associated with this EPG. 216 dentists from São Paulo State, Brazil, completed a questionnaire about three clinical case scenarios involving defective composite restorations with cementum-dentin margins (case 1) and enamel margins (case 2), and an amalgam (case 3) restoration.
View Article and Find Full Text PDFObjectives: Our aims are to describe the characteristics of dentists, members of the US National Dental practice-based research network (PBRN) in the United States, and determine how often these dentists provide specific dental procedures.
Methods: Dentists completed a questionnaire when they enrolled in the Network about their demographic and training characteristics and characteristics of their practices and patients. Dentists also reported the frequency of providing specific dental procedures.
Objectives: To identify causes of the evidence-practice gap (EPG) in dentistry in Japan and analyze whether these causes are associated with: (a) improvement of EPG in minimal intervention dentistry (MID) following an educational intervention and (b) specific dentist characteristics.
Methods: We conducted a mixed-methods questionnaire survey among 197 Japanese dentists that integrated both quantitative and qualitative data. Causative factors for the EPG identified in the quantitative survey were clarified by qualitative analysis.
Introduction: Following inception in 2005 as a multiregional practice-based research network (PBRN), the "National Dental PBRN" expanded nationwide in 2012, and in 2019 implemented additional organizational changes. The objectives are to: (1) describe the new structure and function of the network; and (2) quantify its scientific productivity since 2005.
Methods: A national Administrative and Resource Center is based in Alabama; regional and specialty nodes are based in Alabama, Florida, Illinois, Minnesota, Oregon, New York, and Texas.
Objectives: To understand patients' comfort with health risk assessments (HRAs) and patient and dentist factors associated with the provision of HRAs.
Methods: In this cross-sectional study, 857 patients seen by 30 dental practitioners in the United States National Dental Practice-Based Research Network reported their comfort receiving HRA for six risk factors (tobacco use, alcohol use, dietary sugar intake, human immunodeficiency virus risks, human papillomavirus risks and existing medical conditions) and whether they discussed any of the risk factors during their visits. Multi-level logistic models were used to examine the impacts of patient, practitioner, practice characteristics on the (1) number of risk factors patients were comfortable discussing and (2) number of risk factors assessed in the current dental visit.
Objective: Cracked teeth may be associated with pain, especially biting pain, and to a lesser degree cold and spontaneous pain. Described are how commonly these pains remain constant, develop, or resolve over time, none of which have been well-described, especially among untreated cracked teeth.
Methods: Cracked teeth from the Cracked Tooth Registry (CTR) study were followed for 3 years.
Objectives: To determine whether: the evidence-practice gap (EPG) in minimal intervention dentistry (MID) can be improved by a tailored web-based intervention, and specific clinical situations might impede implementing MID.
Methods: We conducted a before-after intervention study and a qualitative study. Two web-based questionnaire surveys were conducted among 197 Japanese dentists.
Objectives: To evaluate the status of teaching of repair of defective resin-based composite restorations in dental schools in the Middle Eastern and North African (MENA) countries.
Methods: A validated 14-item questionnaire was mailed to the directors of the operative/restorative dentistry department in 40 MENA dental schools. Data were collected on teaching, including whether the repair of resin-based composite restorations was part of the dental school curriculum; the rationale behind the teaching; how techniques were taught, indications for repair, operative techniques, materials used, patient acceptability and expected longevity of the repair procedure.
Background: An important step in integrating dental and medical care is improving understanding of the frequency and characteristics of dental practitioners who conduct health risk assessments (HRAs).
Methods: From September 2017 through July 2018, active dentist and hygienist members of the South Atlantic region of The National Dental Practice-Based Research Network (N = 870) were invited to participate in a survey evaluating their HRA practices (screening, measuring, discussing, referring patients) for 6 health conditions (obesity, hypertension, sexual activities, diabetes, alcohol use, tobacco use). For each health condition, the authors used ordinal logistic regression to measure the associations among the practitioner's HRA practices and the practitioner's characteristics, barriers, and practice characteristics.
Data on dental practices related to caries risk assessment (CRA) are scarce among Brazilian dentists. This study aimed to determine the prevalence of CRA use by dentists and factors associated with its use, as well as to quantify dentists' ratings of the importance of specific factors when treatment planning. Dentists registered at the Regional Council of Dentistry of São Paulo State - Araraquara region were sent two paper questionnaires that comprised: a) characteristics of dentists themselves, their practices, and their patients; and b) the translated version of the "Assessment of Caries Diagnosis and Caries Treatment" Questionnaire from the U.

Methods: A retrospective analysis of 4361 practitioners who enrolled in the Network between April 12, 2012 and October 12, 2018.
Results: Overall, 59% (n = 2586) of practitioners earned CE credit from the Network; among these, 68% (n = 1757) from a video, 38% (n = 993) attended an annual Network meeting, 31% (n = 798) due to training for a Network clinical study, 9% (n = 226) attended a national symposium, and 7% (n = 170) participated in a Network webinar.
Objectives: This study aimed to 1) quantify the evidence-practice gap (EPG) between dental clinical practice and published evidence on Minimal Intervention Dentistry (MID) among dentists in Japan; and 2) examine the hypothesis that dentist characteristics have a significant association with the EPG.
Methods: We conducted a cross-sectional study via use of a web-based questionnaire survey of dentists who were affiliated with the Dental Practice-based Research Network Japan (n = 297). To quantify the EPG on MID, we used a questionnaire that included 10 clinical questions or scenarios to assess concordance between dental practice and published evidence on MID.
Unlabelled: Little is known about dental practice patterns of caries prevention in adults among Brazilian dentists.
Objective: To quantify procedures used for caries prevention for adult patients among dentists from a Brazilian community.
Methods: Dentists (n=197) who reported that at least 10% of their patients are more than 18 years old participated in the first Brazilian study that used a translated version of the "Assessment of Caries Diagnosis and Caries Treatment" from the U.
Objectives: The study objective was to: (1) quantify symptom (pain) and crack changes during one year of follow-up, among teeth that had at least one visible crack at baseline but which did not receive treatment for those cracks; (2) identify any patient traits/behaviors and external tooth/crack characteristics correlated with these changes.
Methods: In this observational study, 209 National Dental Practice-Based Research Network dentists enrolled a convenience sample of 2858 subjects, each with a single, vital posterior tooth with at least one observed external crack; 1850 teeth remained untreated after one year of follow-up and were the cohort for analyses. Data were collected at the patient-, tooth-, and crack-level at baseline, one-year follow up (Y1), and interim visits.
Statement Of Problem: The definitive impression for a single-unit crown involves many material and technique factors that may affect the success of the crown.
Purpose: The purpose of this prospective cohort study was to determine whether impression technique (tray selection), impression material, or tissue displacement technique are associated with the clinical acceptability of the crown (CAC).
Material And Methods: Dentists in the National Dental Practice-Based Research Network documented details of the preparation, impression, and delivery of 3730 consecutive single-unit crowns.
Purpose: This study compared rural to nonrural dentists with respect to opioid prescribing practices, perceptions about prescription drug abuse among patients, and training relevant to pain management and addictions.
Methods: A web-based, cross-sectional questionnaire was administered to practicing dentist members of the National Dental Practice-Based Research Network (PBRN; N = 822) and linked with network enrollment questionnaire data regarding practitioner demographics and practice characteristics. Pain management prescribing practices and perceptions regarding relevance and scope of addiction and drug diversion among patients were assessed.
Statement Of Problem: Despite the high prevalence of posterior cracked teeth, questions remain regarding the best course of action for managing these teeth.
Purpose: The purpose of this clinical study was to identify and quantify the characteristics of visible cracks in posterior teeth and their association with treatment recommendations among patients in the National Dental Practice-Based Research Network.
Material And Methods: Network dentists enrolled patients with a single, vital posterior tooth with at least 1 observable external crack.
