Abstract Background Practice-based research networks offer important opportunities to move recent advances into routine clinical practice. If their findings are not only generalizable to dental practices at large, but can also elucidate how practice characteristics are related to treatment outcome, their importance is even further elevated. Our objective was to determine whether we met a key objective for The Dental Practice-Based Research Network (DPBRN): to recruit a diverse range of practitioner-investigators interested in doing DPBRN studies. Methods DPBRN participants completed an enrollment questionnaire about their practices and themselves. To date, more than 1100 practitioners from the five participating regions have completed the questionnaire. The regions consist of: Alabama/Mississippi, Florida/Georgia, Minnesota, Permanente Dental Associates, and Scandinavia (Denmark, Norway, and Sweden). We tested the hypothesis that there are statistically significant differences in key characteristics among DPBRN practices, based on responses from dentists who participated in DPBRN's first network-wide study (n = 546). Results There were statistically significant, substantive regional differences among DPBRN-participating dentists, their practices, and their patient populations. Conclusion Although as a group, participants have much in common with practices at large; their substantial diversity offers important advantages, such as being able to evaluate how practice differences may affect treatment outcomes, while simultaneously offering generalizability to dentists at large. This should help foster knowledge transfer in both the research-to-practice and practice-to-research directions.

Background: The objectives were to: (1) quantify patient satisfaction with treatment for early dental caries overall, and according to whether or not (2a) the patient received invasive treatment; (2b) was high-risk for dental caries, and had dental insurance; and (3) encourage practitioners to begin using non-invasive approaches to early caries management. Methods: Ten practitioners recorded patient, lesion, and treatment information about non-cavitated early caries lesions. Information on 276 consecutive patients with complete data was included, who received either non-invasive (no dental restoration) or invasive (dental restoration) treatment. Patients completed a patient satisfaction questionnaire and were classified as dissatisfied if they did not "agree" or "strongly agree" with any of 14 satisfaction items. Results: Patients had a mean (± SD) age of 41.8 (±15.8) years, 64% were female and 88% were white. Twenty-five percent (n = 68) were dissatisfied in at least one of the 14 satisfaction items. Satisfaction levels did not significantly vary by patient's gender, race, caries risk category, or affected tooth surface location. Overall, 11% (28 of 276) received invasive treatment; satisfaction did not differ between patients who had invasive or non-invasive treatment. Seven patients received invasive treatment at their request even though that was not what their practitioner recommended; 5 out of 6 were satisfied with their treatment nonetheless. Conclusions: About one-fourth of patients treated for non-cavitated early caries were dissatisfied with at least some aspect of their dental care experience. Satisfaction of patients who received invasive treatment did not differ from those who received non-invasive treatment. [ABSTRACT FROM AUTHOR]

Background. Documenting the gap between what is occurring in clinical practice and what published research findings suggest should be happening is an important step toward improving care. The authors conducted a study to quantify the concordance between clinical practice and published evidence across preventive, diagnostic and treatment procedures among a sample of dentists in The National Dental Practice-Based Research Network ("the network"). Methods. Network dentists completed one questionnaire about their demographic characteristics and another about how they treat patients across 12 scenarios/clinical practice behaviors. The authors coded responses to each scenario/clinical practice behavior as consistent ("1") or inconsistent ("0") with published evidence, summed the coded responses and divided the sum by the number of total responses to create an overall concordance score. The overall concordance score was calculated as the mean percentage of responses that were consistent with published evidence. Results. The authors limited analyses to participants in the United States (N = 591). The study results show a mean concordance at the practitioner level of 62 percent (SD = 18 percent); procedure-specific concordance ranged from 8 to 100 percent. Affiliation with a large group practice, being a female practitioner and having received a dental degree before 1990 were independently associated with high concordance (≥ 75 percent). Conclusion. Dentists reported a medium-range concordance between practice and published evidence. Practical implications. Efforts to bring research findings into routine practice are needed.

Background. The Dental Practice-Based Research Network (DPBRN) provided a means to investigate whether certain procedures were performed routinely. The authors conducted a study to quantify rubber dam use during root canal treatment (RCT) among general dentists and to test the hypothesis that certain dentist or practice characteristics were associated with rubber dam use. Methods. DPBRN practitioner-investigators (P-Is) answered a questionnaire that included items about rubber dam use and other forms of isolation during RCT. DPBRN enrollment questionnaire data provided information regarding practitioner and practice characteristics. Results. A total of 729 (74 percent) of 991 P-Is responded; 524 were general dentists who reported providing at least some RCTs and reported the percentage of RCTs for which they used a rubber dam. Of these 524 P-Is, 44 percent used a rubber dam for all RCTs, 24 percent used it for 51 to 99 percent of RCTs, 17 percent used it for 1 to 50 percent of RCTs, and 15 percent never used it during RCT. Usage varied significantly by geographic region and practice type. The use of cotton rolls and other forms of isolation also was reported. Conclusions. Similar to other reports in the literature, not all DPBRN general dentists used a rubber dam during RCT. Clinical Implications. Because the clinical reference standard is to use a rubber dam during RCT, increasing its use may be important. [ABSTRACT FROM AUTHOR]

The article focuses on the study that examines the materials used by dentists in The Dental Practice-Based Research Network (DPBRN) in putting the first restoration on permanent posterior tooth surfaces. A cross-sectional study was conducted by DPBRN practitioner-investigators and informed consent was sought to patients. The study indicates that amalgam was more often used by practitioner-investigators than direct resin-based composite (RBC) for posterior carious lesions.

Purpose: The purposes of this study were to: (1) evaluate the retention rates of occlusal sealants in children in an urban school-based sealant program run by a County Health Department in Alabama; and (2) assess the clinical benefits of this sealant program by comparing caries experience of a group of participants and nonparticipants. Methods: The records of 2,097 children (mean age=8.1±1.6 years) who received sealants and had at least 1 follow-up examination were analyzed to determine the outcome of sealed and nonsealed surfaces of permanent first molars (PFM). Additionally, 103 fifth-grade students who did and did not participate in the sealant program (P=participants; NP=nonparticipants) were examined by a masked examiner who recorded their PFM condition. Results: Sealants placed by the County Health Department had a retention rate of 71% over an average of 1.6±0.7 years (range=0.5-4.4 years). The patient's age at the initial visit appeared to be the only factor that influenced retention. On average, participants had at least 1 PFM that remained caries-free, compared to nonparticipants (permanent decayed, missing, and filled teeth [DMFT] in NP=1.5±1.4, P=0.5±0.8; <.016). Conclusions: Retention rates for occlusal sealants in this public health program were similar to those reported in previous clinical studies. Furthermore, children who had sealants had significant protection from occlusal decay up to grade 5. [ABSTRACT FROM AUTHOR]

Objective: Following a successful 2005-2012 phase with three regional practice-based research networks (PBRNs), a single, unified national network called ''The National Dental PBRN'' was created in 2012 in the United States to improve oral health by conducting practice-based research and serving dental professionals through education and collegiality. Methods: Central administration is based in Alabama. Regional centres are based in Alabama, Florida, Minnesota, Oregon, New York and Texas, with a Coordinating Centre in Maryland. Ideas for studies are prioritized by the Executive Committee, comprised mostly of full-time clinicians. Results: To date, 2763 persons have enrolled, from all six network regions; enrollment continues to expand. They represent a broad range of practitioners, practice types, and patient populations. Practitioners are actively improving every step of the research process, from idea generation, to study development, field testing, data collection, and presentation and publication. Conclusions: Practitioners from diverse settings are partnering with fellow practitioners and academics to improve clinical practice and meet the needs of clinicians and their patients. Clinical significance: This ''nation's network'' aims to serve as a precious national resource to improve the scientific basis for clinical decision-making and foster movement of the latest evidence into routine practice.
