Adverse childhood experiences and dental cleaning during pregnancy: Findings from the North and South Dakota PRAMS, 2017-2021.

OBJECTIVE: Research demonstrates that adverse childhood experiences (ACEs)-that is, experiences of abuse, neglect, and household dysfunction-are related to lower preventive dental care utilization in childhood and adolescence. However, limited research has explored the connection between ACEs and preventive dental care utilization in adulthood, and no research has examined this relationship during pregnancy. The current study extends existing research by investigating the relationship between ACEs and dental cleaning and dental care utilization during pregnancy among a sample of women who delivered live births in North Dakota and South Dakota. METHODS: Data are from the 2017 to 2021 Pregnancy Risk Assessment Monitoring System (PRAMS) in North Dakota and South Dakota (n = 7391). Multiple logistic regression is used to examine the relationship between the number of ACEs (0, 1, 2, 3 or 4 or more) and dental cleaning during pregnancy. RESULTS: Relative to respondents with 0 ACEs, those with 4 or more ACEs were significantly less likely to report having dental care during pregnancy (OR = 0.757, 95% CI = 0.638, 0.898). By racial and ethnic background, the results showed that the significant associations are concentrated among White and Native American respondents. CONCLUSIONS: The results suggest that exposure to 4 or more ACEs is associated with a significantly lower likelihood of dental cleaning during pregnancy among women who delivered a live birth in North Dakota and South Dakota. Further investigations are necessary to understand the mechanisms underlying the relationship between ACEs and dental cleaning during pregnancy and replicate the findings in other geographic contexts.

Recruitment strategies and retention rates for five National Dental PBRN studies.

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. The proportion of patients who either attended a follow-up (FU) assessment or completed an online assessment was calculated. For studies with multiple FU visits or questionnaire assessments, rates for completing each FU were calculated, as were the rates for completing any and for completing all FU assessments. The associations of practitioner and patient characteristics with all clinic FU visits, and with the completion of all assessments for a study were ascertained. Results: Overall, 591 practitioners and 12,159 patients were included. FU rates by patients for any assessment varied from 91% to 96.5%, and rates for participating in all assessments ranged from 68% to 87%. The mean total number of patients each practitioner recruited was 21 (sd = 15); the mean number per study was 13 (sd = 7). For practitioners, practice type and patient enrollment were associated with greater clinic retention, while only race was associated with their patients completing post-visit online assessments. For patients, age was associated with clinic retention, while female gender, age, race, and education were all associated with greater completion of post-visit online assessments. Conclusion: The Network efficiently recruited practitioners and patients and achieved high patient retention rates for the five studies.

Patient and dentist perspectives on collecting patient reported outcomes after painful dental procedures in the National Dental PBRN.

BACKGROUND: Dental Patient Reported Outcomes (PROs) relate to a dental patient's subjective experience of their oral health. How practitioners and patients value PROs influences their successful use in practice. METHODS: Semi-structured interviews were conducted with 22 practitioners and 32 patients who provided feedback on using a mobile health (mHealth) platform to collect the pain experience after dental procedures. A themes analysis was conducted to identify implementation barriers and facilitators. RESULTS: Five themes were uncovered: (1) Sense of Better Care. (2) Tailored Follow-up based on the dental procedure and patient's pain experience. (3) Effective Messaging and Alerts. (4) Usable Digital Platform. (5) Routine mHealth Integration. CONCLUSION: Frequent automated and preferably tailored follow-up messages using an mHealth platform provided a positive care experience for patients, while providers felt it saved them time and effort. Patients thought that the mHealth questionnaires were well-developed and of appropriate length. The mHealth platform itself was perceived as user-friendly by users, and most would like to continue using it. PRACTICAL IMPLICATIONS: Patients are prepared to use mobile phones to report their pain experience after dental procedures. Practitioners will be able to close the post-operative communication gap with their patients, with little interruption of their workflow.

The Patient Protection and Affordable Care Act and oral health care use among formerly incarcerated people in the United States.

BACKGROUND: Formerly incarcerated people report less frequent oral health care use, despite having more substantial oral health problems. This study aimed to determine whether the adoption of the Patient Protection and Affordable Care Act (ACA) has improved oral health care use among formerly incarcerated people in the United States. METHOD: Data were from Wave I (1994-1995), Wave IV (2008), and Wave V (2016-2018) of the National Longitudinal Study of Adolescent to Adult Health (n = 9,108), a nationally representative cohort study in the United States. RESULTS: On the basis of the results of multiple logistic regression analysis with interaction terms, the authors found a positive and statistically significant interaction between prior incarceration and living in a state with ACA adoption on past-year oral health care use, net of potential confounding variables (incarceration × ACA: odds ratio, 1.587; 95% CI, 1.043 to 2.414). Substantively, the findings suggest that people with a history of incarceration are less likely to use oral health care, and this disparity is more likely to occur in states without ACA adoption. CONCLUSIONS: ACA adoption corresponds with improvements in the receipt of oral health care among formerly incarcerated people. PRACTICAL IMPLICATIONS: This study builds on prior evidence highlighting that the ACA is beneficial in connecting formerly incarcerated people to health care services and suggests that these benefits may extend to improving access to and use of oral health care.

Food deserts and dental care utilization in the United States.

OBJECTIVES: Although food deserts are known to impact health and healthcare utilization, no research has investigated the relationship between food deserts and dental care utilization. This study aimed to fill this gap by assessing the relationship between living in a food desert and self-reported dental care utilization in the past year. METHODS: Data are from the National Longitudinal Study of Adolescent to Adult Health (N = 10,495). The association between food deserts and dental care utilization was assessed using covariate-adjusted multiple logistic regression. RESULTS: Living in a food desert was associated with higher odds of not utilizing dental care in the past year. This association was concentrated among high-poverty areas (≥20% poverty rate). CONCLUSIONS: The current study is the first to assess the relationship between living in a food desert and dental care utilization. The findings demonstrate that individuals living in low-income urban food deserts may be at increased risk for not utilizing dental care.

Adverse Childhood Experiences and Dental Care Utilization During Pregnancy: Findings from the North and South Dakota PRAMS, 2017-2021.

Background: Research demonstrates adverse childhood experiences (ACEs)-i.e., experiences of abuse, neglect, and household dysfunction-adversely impact healthcare utilization over the life course. Several studies demonstrate that ACEs are related to lower dental care utilization in childhood and adolescence. However, limited research has explored the connection between ACEs and dental care utilization in adulthood, and no research has examined this relationship during pregnancy. The current study extends existing research by investigating the relationship between ACEs and dental care utilization during pregnancy. Data: Data are from the 2017-2021 Pregnancy Risk Assessment Monitoring System (PRAMS) North Dakota and South Dakota (n = 7,391). Multiple logistic regression is used to examine the relationship between the number of ACEs and dental care utilization. Findings: Relative to respondents with 0 ACEs, those with 4 or more ACEs were significantly less likely to report having dental care during pregnancy (OR = 0.745, 95% CI = .628, .883). By racial and ethnic background, the results showed that the significant associations are concentrated among White and Native American respondents. Conclusions: The results suggest that exposure to 4 or more ACEs is associated with a significantly lower likelihood of dental care utilization in adulthood, and this relationship is concentrated among White and Native American respondents. Further investigations are necessary to understand the mechanisms underlying the relationship between ACEs and dental care utilization and replicate the findings in other geographic contexts.

Physical intimate partner violence and prenatal oral health experiences in the United States.

BACKGROUND: Intimate partner violence (IPV) is a significant public health issue, and when experienced during pregnancy, IPV substantially harms maternal health. Still, limited research has examined how IPV may influence prenatal oral health and dental care utilization. This study investigates the relationship between IPV during pregnancy and women's oral health experiences. DATA: Data are from 31 states from 2016-2019 in the United States that participated in the Pregnancy Risk Assessment Monitoring System (N = 85,289)-a population-based surveillance system of live births conducted annually by the Centers for Disease Control and Prevention and state health departments. Multivariable logistic regression analyses were used to examine the association between physical IPV during pregnancy (measured by being pushed, hit, slapped, kicked, choked, or physically hurt any other way by a current or ex-husband/partner) and various oral health experiences. FINDINGS: Women who experienced prenatal physical IPV reported worse oral health experiences during pregnancy, including being more likely to report not knowing it was important to care for their teeth, not talking about dental health with a provider, needing to see a dentist for a problem, going to see a dentist for a problem, as well as having more unmet dental care needs. CONCLUSIONS: Together, these findings indicate that women who experience physical IPV during pregnancy have lower knowledge of prenatal oral health care, more oral health problems, and greater unmet dental care needs. Given the risk of IPV and oral health problems for maternal and infant health, the study findings point to greater attention toward the oral health needs of IPV-exposed pregnant women.

Characteristics of dentists in the National Dental Practice-Based Research Network.

OBJECTIVES: 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. Data were analyzed using descriptive statistics. RESULTS: Of 4,483 dentists in active clinical practice, 34% identified as females, 70% as white, and 73% as general dentists. Most dentists practiced in large metropolitan areas (87%) and in solo or small practices (72%). On average, they reported about one-half of their patients were children or older adults, a third were from historically underrepresented racial and ethnic groups, and one-quarter were covered by public insurance. Most dentists routinely performed restorations and fixed prosthetics (78%), extractions (59%), removable (44%) and implant (40%) prosthetics, and endodontics on incisor and premolar teeth (44%). CONCLUSIONS: Dentists participating in the National Dental PBRN have much in common with dentists at large. The network has a broad representation of dentists, practice types, patient populations, and treatments offered, including diversity regarding race/ethnicity, gender, insurance, and geography of its practitioners and patients. CLINICAL SIGNIFICANCE: Characteristics of National Dental PBRN dentists suggest that a broad range of dentists is interested in participating in national-level research studies, thereby enabling an array of clinical study settings and topics that can optimize the generalizability of study findings.

Intimate Partner Violence and Prenatal Oral Health Experiences.

Background: Intimate partner violence (IPV) is a significant public health issue, and when experienced during pregnancy, IPV poses substantial harms for maternal health. Still, limited research has examined how IPV may influence prenatal oral health and dental care utilization. This study aims to investigate the relationship between IPV during pregnancy and women's oral health experiences. Data: Data are from the Pregnancy Risk Assessment Monitoring System from 2016 through 2019 (N = 85,289). Multivariable logistic regression analyses were used to examine the association between physical IPV during pregnancy and various oral health experiences. Findings: Women who experienced prenatal physical IPV reported worse oral health experiences during pregnancy, including being more likely to report not knowing it was important to care for their teeth, not talking about dental health with a provider, needing to see a dentist for a problem, going to see a dentist for a problem, as well as having more unmet dental care needs. Conclusions: Together, these findings indicate that women who experience physical IPV during pregnancy have lower knowledge of prenatal oral health care, more oral health problems, and greater unmet dental care needs. Given the risk associated with IPV and oral health problems for maternal and infant health, the study findings point to greater attention toward the oral health needs of IPV-exposed pregnant women.

Dental practitioner approaches to bruxism: Preliminary findings from the national dental practice-based research network.

OBJECTIVE: Bruxism is a repetitive masticatory muscle activity. This study investigates dental practitioners' approaches to bruxism assessment and treatment in practices. METHODS: A brief 5 question questionnaire ("Quick Poll") on bruxism was conducted. RESULTS: A total of 397 practitioners responded. More than half (55%) initiated treatment for bruxism on one to three patients per month. The majority believed that stress (97%) and sleep patterns (82%) affected bruxism in their patients. Interestingly, 96% offered an occlusal guard/appliance and 46% made occlusal adjustments. CONCLUSION: This study highlights inconsistencies in practitioner approaches to bruxism assessment and management in clinical settings, suggesting gaps in practitioner knowledge evidenced by the varied responses.

Study protocol: understanding pain after dental procedures, an observational study within the National Dental PBRN.

BACKGROUND: Patient-reported outcome measures provide an essential perspective on the quality of health care provided. However, how data are collected, how providers value and make sense of the data, and, ultimately, use the data to create meaningful impact all influence the success of using patient-reported outcomes. OBJECTIVES: The primary objective is to assess post-operative pain experiences by dental procedure type through 21 days post-procedure as reported by patients following dental procedures and assess patients' satisfaction with pain management following dental surgical procedures. Secondary objectives are to: 1) assess post-operative pain management strategies 1 week following dental surgical procedures, as recommended by practitioners and reported by patients, and 2) evaluate practitioner and patient acceptance of the FollowApp.Care post visit patient monitoring technology (FollowApp.Care). We will evaluate FollowApp.Care usage, perceived usefulness, ease of use, and impact on clinical workload. DESIGN AND METHODS: We describe the protocol for an observational study involving the use of the FollowApp.Care platform, an innovative mobile application that collects dental patients' assessments of their post-operative symptoms (e.g., pain). The study will be conducted in collaboration with the National Dental Practice-based Research Network, a collective Network of dental practices that include private and group practices, public health clinics, community health centers and Federal Qualified Health Centers, academic institutional settings, and special patient populations. We will recruit a minimum of 150 and up to 215 dental providers and up to 3147 patients who will receive push notifications through text messages FollowApp.Care on their mobile phones at designated time intervals following dental procedures. This innovative approach of implementing an existing and tested mobile health system technology into the real-world dental office setting will actively track pain and other complications following dental procedures. Through patients' use of their mobile phones, we expect to promptly and precisely identify specific pain levels and other issues after surgical dental procedures. The study's primary outcome will be the patients' reported pain experiences. Secondary outcomes include pain management strategies and medications implemented by the patient and provider and perceptions of usefulness and ease of use by patients and providers.

Dental Sleep Medicine among dental practitioners: Preliminary findings from the National Dental Practice-Based Research Network.

Objectives/Introduction: Dental sleep medicine (DSM) focuses on oral appliance therapy (OAT) to manage sleep-disordered breathing (SDB), including obstructive sleep apnea (OSA). This brief poll aimed to assess the interest and practices of dental practitioners in DSM. To this day lack of data exists regarding how DSM practices function in the clinical setting. Therefore, identifying knowledge gaps in DSM among dental practitioners may improve patient outcomes. Methods: A preliminary brief questionnaire ("Quick Poll") on DSM was conducted through the National Dental Practice-Based Research Network (Network) members (n=311). The poll contained five questions about DSM. Results: Results showed that 66% of practitioners have involvement in DSM patient care. A total of 44% of practitioners who answered the Quick Poll do not screen for snoring or SDBs. About 40% of respondents are either interested in continuing education courses on the topic or had already taken multiple courses on DSM. The top three topics of DSM research of interest to practitioners were various DSM practice models, response to OAT, and compliance with OAT. Conclusion: Network dental practitioner respondents face challenges regarding the treatment of SDBs. Despite these challenges, most practitioners are interested in engaging in DSM. Based on these preliminary findings, there are informational needs regarding the current state of clinical care, side effects of OAT, choice of OAT, titration protocols, and patient outcomes.

Structure, function, and productivity from the National Dental Practice-Based Research Network.

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. A Network Coordinating Center is based in Oregon. Studies are funded via investigator-initiated grants. Scientific productivity is assessed using specific metrics, including the Relative Citation Ratio. Results: To date, 58 studies have been completed or are in data collection or development. These studies have investigated a broad range of topics using a wide variety of study designs. Of the studies that have completed enrollment, 70,665 patients were enrolled, as were 19,827 practitioners (some participated in multiple studies), plus electronic records for 790,493 patients in two data-only studies. To date, these studies have led to 193 peer-reviewed scientific publications in 62 different journals. The mean (1.40) Relative Citation Ratio of Network publications connotes a greater-than-average influence in their fields. Conclusions: These metrics demonstrate that the PBRN research context can successfully engage practitioners and patients from diverse settings nationally with a high and sustained level of scientific productivity. This infrastructure has enabled clinical scientists in oral health and nonoral health topics and provided additional recruitment venues outside of the typical academic health center research context.

Onset and resolution of pain among treated and untreated posterior teeth with a visible crack: Three-year findings from the national dental practice-based research network.

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.  Assessments of cold, biting, and spontaneous pain and treatments performed were completed at enrollment (Y0) and at each annual recall visit. RESULTS: 209 practitioners enrolled 2,858 patients, each with a visible crack on a posterior tooth; 2601 (91%) patients attended at least one recall visit. Overall, 960 (37%) were treated, primarily with crowns. Among both treated and untreated cracked teeth with biting pain or spontaneous pain at Y0, the vast majority (92-99%) had their pain resolved by the time of a recall visit and 85-93% remained pain-free after initial resolution. The observations for cold pain were similar: 68% (untreated) and 78% (treated) became free of cold pain at some point during follow-up, and 84% of these stayed free of cold pain after initial resolution. Few teeth developed biting or spontaneous pain (4-8%) and 44-67% of these had pain resolution during the follow-up period. CONCLUSION: In this study, treatment resolved a preponderance of pain associated with a cracked tooth.  Pain was also resolved for most untreated cracked teeth, especially biting pain, and to a lesser degree spontaneous and cold pain, although not to the same degree as with the treated cracked teeth.

Outcomes of treatment and monitoring of posterior teeth with cracks: three-year results from the National Dental Practice-Based Research Network.

OBJECTIVES: To describe treatment and monitoring outcomes of posterior teeth with cracks at baseline followed in the National Dental Practice-Based Research Network for up to three years. MATERIALS AND METHODS: Two hundred and nine dentists enrolled a convenience sample of 2,858 patients, each with a posterior tooth with at least one visible crack and followed them for three years. Characteristics at the patient, tooth, and crack level were recorded at baseline and at annual recall visits. Data on all teeth referred for extraction were reviewed. Data on all other teeth, treated or monitored, seen at one or more recall visits were reviewed for evidence of failure (subsequent extraction, endodontics, or recommendation for a re-treatment). RESULTS: The survival rate for teeth with cracks at baseline exceeded 98% (only 37 extractions), and the failure rate for teeth that were treated restoratively was only 14%. Also, only about 14% of teeth recommended at baseline for monitoring were later recommended to be treated, and about 6.5% of teeth recommended for monitoring at baseline were later treated without a specific recommendation. Thus, about 80% of teeth recommended at baseline for monitoring continued with a monitoring recommendation throughout the entire three years of the study. Treatment failures were associated with intracoronal restorations (vs. full or partial coverage) and male patients. CONCLUSIONS: In this large 3-year practice-based study conducted across the USA, the survival rate of posterior teeth with a visible crack exceeded 85%. Clinical relevance Dentists can effectively evaluate patient-, tooth-, and crack-level characteristics to determine which teeth with cracks warrant treatment and which only warrant monitoring.

Development of a Mobile Application to Enhance Knowledge, Awareness and Communication of Dry Mouth Amongst Dental Practitioners and Patients: A South Texas Oral Health Network Study.

BACKGROUND: Dry mouth, also commonly known as "xerostomia", is a prominent symptom that is often overlooked by dental practitioners and patients. The purpose of this study was to pilot the development of a mobile application for assessing dry mouth symptoms. The application will allow patients to self-assess and enhance knowledge, awareness and communication with dental practitioners in their management of dry mouth. METHOD: The first phase of the study was to draw on common knowledge and awareness by conducting two focus groups of dental professionals and community members on content, practicality, functionality, design, and effectiveness. The second phase of the study was the development of the dry mouth mobile application followed by the third phase of the study that consisted of face-validity interviews to obtain feedback on the application. RESULTS: Fifty two percent (n=15) of the dental professionals estimated being aware of the prevalence of dry mouth in 40% or more of their patients. Thirty Nine percent of (n=9) community estimated being aware of the prevalence of dry mouth in 40% or more of the community. When asked about their awareness of the etiologies of dry mouth, 100% (n=29) of dental professionals reported that multiple medications and smoking were primary factors whereas the community members indicated that illness and dehydration (87%, n=20) were primary factors in dry mouth. Dental professional's (25% n=7) were very confident in recognizing symptoms and 28% (n=8) were very confident they knew how to manage dry mouth symptoms. Furthermore, 22% (n=5) of the community members were also very confident about recognizing dry mouth symptoms and 13% (n=3) were very confident knowing how managing it. The ToP report generated from the discussions identified "themes" that were utilized in the development of the mobile application. Most individuals who participated in the validity interviews agreed that the dry mouth mobile application was useful, appealing, easy to use and the self-assessment test gave clear and concise information. The application was made available to download from the iTunes Appstore (2019-2020). CONCLUSION: The dry mouth pilot study indicated that the mobile application was beneficial for self-assessment and easy to use. Development of advanced technology tools such as the dry mouth application can promote communication between patients and their dental practitioners to discuss management options for dry mouth.

Development of an E-Cigarettes Education and Cessation Program: A South Texas Oral Health Network Study.

Electronic cigarette (e-cigarette) use, or vaping, among youth and young adults has become a major public health concern. The prevalence of vaping has grown an astounding 900% among high school students from 2011 to 2015, and e-cigarette use among high school students has increased by 78% from 2017 to 2018, largely due to the rise in popularity of the high-dose nicotine product, JUUL. To date, there are few evidence-based e-cigarette cessation programs. To address this need, the South Texas Oral Health Network collaborated with dental practitioners and community members to conduct focus groups assessing knowledge and awareness of e-cigarette use. Based on this feedback, we developed a dental practitioner-based e-cigarette cessation program. The next step will be to utilize this program in a practice-based research network, a "real-world" practice setting that has the potential to increase the number of dental practitioners who counsel their patients about ecigarettes.

Baseline characteristics as 3-year predictors of tooth fracture and crack progression: Findings from The National Dental Practice-Based Research Network.

BACKGROUND: The authors of this practice-based study estimated the risk of experiencing tooth fractures and crack progression over 3 years and correlated baseline patient-, tooth-, and crack-level characteristics with these outcomes. METHODS: Two-hundred-and-nine National Dental Practice-Based Research Network dentists enrolled a convenience sample of 2,601 participants with a cracked vital posterior tooth that had been examined for at least 1 recall visit over 3 years. Data were collected at the patient, tooth, and crack levels at baseline, annual follow-up visits, and any interim visits. Associations between these characteristics and the subsequent same-tooth fractures and crack progression were quantified. RESULTS: Of the 2,601 teeth with a crack or cracks at baseline, 78 (3.0%; 95% confidence interval, 2.4% to 3.7%) subsequently developed a fracture. Of the 1,889 patients untreated before year 1, 232 (12.3%; 95% confidence interval, 10.9% to 13.8%) had some type of crack progression. Baseline tooth-level characteristics associated with tooth fracture were the tooth was maxillary and had a wear facet through enamel and a crack was detectable with an explorer, on the facial surface, and in a horizontal direction. Crack progression was associated with males and teeth with multiple cracks at baseline; teeth with a baseline facial crack were less likely to show crack progression. There was no commonality between characteristics associated with tooth fracture and those associated with crack progression. CONCLUSIONS: Development of tooth fractures and crack progression over 3 years were rare occurrences. Specific characteristics were associated with the development of tooth fracture and crack progression, although none were common to both. PRACTICAL IMPLICATIONS: This information can aid dentists in assessing factors that place posterior cracked teeth at risk of experiencing adverse outcomes.

Practitioner Engagement in Activities of the National Dental Practice-Based Research Network (PBRN): 7-Year Results.

PURPOSE: To 1) quantify practitioner activities of the National Dental Practice-Based Research Network (Network) for which Continuing Education (CE) credits were received (study training, videos, webinars, meetings, and symposia); 2) quantify practitioner coauthoring Network publications and presentations; and 3) test whether practitioner characteristics were associated with participation in these activities. 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. Members of 2 large group practices earned on average more CEs than practitioners from other practice settings. Four percent (n = 159) of practitioners coauthored a Network presentation or publication. Practitioners who received their dental degree before 2000, were general practitioners, or were members of 2 large group practices, were more likely to have coauthored a publication or presentation. CONCLUSION: This Network used a broad range of activities to engage community practitioners. These activities were successful in sustaining a high level of practitioner engagement in clinical research and its relevance to everyday clinical practice.

Prophylactic antibiotic prescribing in dental practice: Findings from a National Dental Practice-Based Research Network questionnaire.

BACKGROUND: Little is known about antibiotic prescribing practices of dentists. The objective of this study was to gain a better understanding of dentists' beliefs and behaviors regarding the use of antibiotic prophylaxis (AP) before invasive dental procedures. METHODS: A multidisciplinary team developed and disseminated a questionnaire to 3,584 dentist members of the National Dental Practice-Based Research Network. RESULTS: Overall, 2,169 network dentists (61%) responded. Respondents saw patients at risk of developing infective endocarditis (IE) and prosthetic joint infection (PJI) at least once per week (35% and 65%, respectively). Although 78% of dentists agreed that the 2007 American Heart Association guidelines for the prevention of IE are well-defined and clear, only 49% agreed concerning PJI guidelines. Differences for the IE and PJI patient populations also existed for questions regarding dentists' understanding of the specific patient groups at risk, the recommended antibiotic regimens, and the need to consult with a patient's cardiologist or orthopedic surgeon. CONCLUSIONS: The survey results indicate that decision making regarding the use of AP occurs frequently among dentists. Moreover, dentists reported uncertainty about the appropriate use of AP as defined by both IE and PJI guidelines, which may have resulted in a lack of concordance between dentists' beliefs and their practice behaviors. PRACTICAL IMPLICATIONS: The results reported by the authors highlight the need to develop better educational programs that address antimicrobial stewardship in AP for patients at risk of developing IE and PJI and target the dental profession.
