Periodontal-Systemic Disease Education in U.S. and Canadian Dental Schools

Patient awareness of the association between periodontal and systemic diseases in an academic setting

BACKGROUND

Periodontal diseases (PD) have been increasingly associated with several systemic conditions such as cardiovascular disease (CVD), diabetes mellitus (DM), rheumatoid arthritis (RA), and Alzheimer's disease (AD). This study aimed to gain insight into patients' awareness of the association between PD and systemic diseases.

METHODS

A survey was developed to analyze patient awareness of the association between PD and systemic diseases. Descriptive and categorical variables were summarized with counts and percentages. Chi-squared tests were used to evaluate differences between variables. A linear logistical regression model was used to assess the simultaneous, independent association between each variable.

RESULTS

Data from 161 completed surveys were analyzed. The majority of the participants (61.49%) reported awareness of symptoms of PD, but only 36.36% identified all its major symptoms. Individuals reporting awareness of the association between PD and systemic diseases was 48.4%, 31.7%, 14.9%, and 9.9% for CVD, DM, RA, and AD, respectively. Patients aged ≥51 years and males were more aware of the association between PD and CVD. Increased awareness of an association between PD and DM was observed among patients who had a higher frequency of dental visits and those with a self-reported history of DM.

CONCLUSIONS

This study provides insight that, even with the vast amount of scientific knowledge on the inter-relationships that exist between PD and systemic diseases, most patients are still unaware of these associations. This research identified that improvement of health literacy surrounding PD, their symptoms, and their association with systemic diseases may be warranted.

Implementing a Prenatal Oral Health Program for Dental Students: Lessons Learned

The Prenatal Oral Health Program (pOHP) was developed to educate dental students on prenatal oral health and promote access to dental care for pregnant women. Program advancement has occurred in support of quality improvement. This mixed-methods design combined quantitative data from fourth-year dental students who participated the pOHP (N = 81) and qualitative data from a student-faculty-staff focus group discussion (N = 7). Different clinical structures, appropriate leveling in the curriculum, management with a patient care coordinator, and inclusion of interprofessional learning experiences (IPE) were compared. The survey response rate was 96.4% (N = 81). Trends were noted between students who provided clinical care for a pregnant patient (31%) versus those who did not. Results indicated that an integrated clinic was preferred, though students who had treated a pOHP patient showed greater support for a standalone clinic model. Survey and focus group data agreed that pOHP should occur during the third-year dental school training; however, students with patient experience favored second-year placement. Survey and focus group data emphasize the importance of a patient care coordinator for clinical management and IPE as an essential learning element. Innovating new clinical models requires a period of evolution to determine preferred and sustainable infrastructure. Results reveal the advantages and disadvantages of various program implementation models and demonstrate that student perceptions were influenced by their clinical experiences. Study findings will inform implementation and guide other programs as they create and modify existing curricula to enhance prenatal oral health.

Digital Form for Assessing Dentistry Undergraduates Regarding Periodontal Disease Associated with Cardiovascular Diseases

Background: Throughout recent years, periodontal disease (PD) has been linked to innumerable medical systemic conditions, such as cardiovascular disease (CVD). This association could negatively impact oral health, so the knowledge of dentists who have graduated must follow modern dentistry in order to promote oral health, mainly in systemically compromised patients. Therefore, the present study aimed to determine and evaluate the knowledge level of dentistry undergraduate students (DUS) regarding the correct periodontal treatment and management of cardiac patients with PD. Methods: This cross-sectional and populational-based study was conducted between March and June 2022 in northern Brazil. A total of 153 DUS received an anonymous digital form (Google Forms Platform) using a non-probabilistic “snowball” sampling technique. The digital form was composed of four blocks of dichotomous and multiple-choice questions. After signing the informed consent term, DUS were divided into three groups according to their period/semester in dentistry graduation during the study time (G1: 1st period/semester; G2: 5th period/semester and G3: 10th period/semester). A total of 25 questions referring to demographic, educational and knowledge data about the dental and periodontal care of cardiac patients with PD were asked, and all data were presented as descriptive percentages and then analyzed using the Kappa test. Results: From a total of 153 (100%) DUS, the sample was mostly composed of 104 (68%) female participants, with an average age of 21.1 years. Regarding basic knowledge, the majority of answers were no, with G1 being higher than G2 and G3. Regarding clinical questions, 1247 (58.3%) answers were no. Additionally, regarding fundamental clinical questions 1, 2, 3, 7, 9, 11, 13 and 14, the majority of G1, G2 and G3 answered no, demonstrating a major lack of knowledge. Conclusions: In our study, DUS demonstrated a low knowledge level of the dental and periodontal care of cardiac patients with PD and its bi-directional link. Thus, according to our results, an improvement in dentistry educational programs regarding periodontal medicine must be implemented.

A Multi-Institutional Study of Dental Student Readiness to Address Adolescent Risk Behaviors

The aim of this replication study was to determine if prior findings at one U.S. dental school about dental students' comfort discussing and perceptions of the relevance of 15 risk behaviors to adolescent patient oral health care would be observed at other institutions. All first- and fourth-year dental students (n=414) at three U.S. dental schools in fall 2017 were invited to participate, and 218 completed the survey (52.7% response rate). These students reported feeling comfortable to uncomfortable discussing risk behaviors with adolescent patients, yet perceived those risk behaviors as relevant to their oral health. There were significant differences in student comfort discussing risk behaviors with adolescents and their perceptions of relevance by gender, age, class status, and school location. Males were more comfortable than females discussing oral health risk behaviors. There were no significant differences by race/ethnicity. Fourth-year students had higher levels of comfort discussing risk behaviors than first-year students. Compared to students in the South and Midwest schools, students at the West school were more comfortable discussing selected topics and had higher perceptions of their relevance to adolescent oral health care. These results suggest there is room for improvement in this area of dental education. Dental schools should aim to strengthen students' knowledge of and comfort in discussing oral health risk behaviors with adolescent patients with the use of educational activities and clinical experiences.

Clinical research activity in periodontal medicine: a systematic mapping of trial registers

AIM

The primary aim of the study was to systematically map registration records on periodontal medicine in clinical trial registers. The secondary aim was to assess the evolution of periodontal medicine in clinical periodontal research as a whole.

MATERIAL AND METHODS

We searched all registration records related to periodontology in the World Health Organization International Clinical Trials Registry Platform. For registration records classified in the field of periodontal medicine, we assigned the 2015 MeSH(®) term for the most precisely corresponding systemic condition.

RESULTS

Fifty-seven systemic conditions have been hypothesized to be linked with periodontal diseases, covering nearly 2% of the diseases indexed in MeSH. In addition to diabetes, cardiovascular disease or preterm birth, other systemic conditions have been the subject of registration records, such as anaemia, liver diseases, dyspepsia or ankylosing spondylitis. A trend towards increasing diversification of systemic conditions has appeared over time. About a third of registration records in clinical periodontal research deals with periodontal medicine.

CONCLUSIONS

Periodontal medicine now constitutes an important part of clinical periodontal research. Research activity in periodontal medicine has grown continuously since the early 2000s, and exploration of registers gives a useful up-to-date snapshot of this constantly evolving field of research.

Oral diseases and diabetes: Nigerian medical and dental caregivers' perspective

OBJECTIVES

The objective was to determine the knowledge of medical and dental caregivers regarding the link between oral diseases and diabetes mellitus (DM); and their role in the management of the oral complications of DM.

MATERIALS AND METHODS

This comparative study was carried out among a group (n = 100) of resident doctors undergoing postgraduate training in medicine and dentistry at a Nigerian Teaching Hospital. A 28-item self-administered questionnaire was used for data collection and it elicited information on respondents' demographics, practice behaviors, knowledge about link between oral diseases, and DM, as well as their knowledge about oral complications of DM.

RESULTS

Majority of the dental senior residents (83.3%) had adequate knowledge of the oral manifestation of DM and the link between oral disease and DM while only 43.8% of the medical junior residents had adequate knowledge (P = 0.060). Majority (63.0%) who strongly agreed that physicians need to collaborate with dental professionals to reduce DM patients' risk of developing oral diseases belonged to the dental group (P = 0.040) and only 35.3% of medical group strongly agreed that physicians should be taught how to screen for oral disease in DM patients (P = 0.009). A vast majority (89.6%) of the medical group however felt that they needed additional information about the link between oral disease and DM (P = 0.036).

CONCLUSION

The findings indicate that there is still a major gap in knowledge of the link between oral diseases and DM; as well as a poor appreciation of the need for a collaborative management of DM patients by medical and dental practitioners.

Knowledge, awareness, and behaviors of endocrinologists and dentists for the relationship between diabetes and periodontitis

AIMS

This study aimed to compare the opinions of dentists and endocrinologists regarding diabetes mellitus (DM) and periodontitis, and to investigate the possible effects on their practice.

METHODS

Cross-sectional data were collected from 297 endocrinologists and 134 dentists practicing in southern China using two separated questionnaires. Questions were close-ended or Likert-scaled. Statistical analyses were done by descriptive statistics, bivariate and binary logistic regression analysis.

RESULTS

Compared with endocrinologists, dentists presented more favorable attitudes for the relationship of DM and periodontitis (P<0.001). 61.2% of dentists reported they would frequently refer patients with severe periodontitis for DM evaluation, while only 26.6% of endocrinologists reported they would frequently advise patients with DM to visit a dentist. Nearly all of the respondents (94.4%) agreed that the interdisciplinary collaboration should be strengthened. The logistic regression analysis exhibited that respondents with more favorable attitudes were more likely to advise a dental visit (P=0.003) or to screen for DM (P=0.006).

CONCLUSIONS

Endocrinologists and dentists are not equally equipped with the knowledge about the relationship between DM and periodontitis, and there is a wide gap between their practice and the current evidence, especially for endocrinologists. It's urgent to take measures to develop the interdisciplinary education and collaboration among the health care providers.

Periodontopathogen profile of healthy and oral lichen planus patients with gingivitis or periodontitis

Oral lichen planus (OLP) is a chronic inflammatory disease that is frequently detected in oral tissues. The aim of our study was to identify the prevalence of the detection of periodontopathogenic microorganisms (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Treponema denticola in OLP patients and to compare with this prevalence of periodontopathogenic microorganisms in healthy non-OLP patients. Our study included 27 (18 chronic periodontitis (OLPP) and 9 gingivitis (OLPG)) patients diagnosed with OLP along with 26 (13 chronic periodontitis (HP) and 13 gingivitis (HG)) healthy non-OLP patients. The multiplex polymerase chain reaction (PCR) with subsequent reverse hybridization method (micro-IDent) was used for identifying periodontopathogenic microorganisms present in subgingival plaque samples. The percentages of detection for A. actinomycetemcomitans, P. gingivalis, P. intermedia, T. forsythia and T. denticola in subgingival plaque samples taken from OLP patients (OLPG and OLPP) were 18.5%, 85.1%, 81.4%, 88.8% and 74%, respectively. Meanwhile, in the non-OLP patients (HG and HP), these values were 7.6%, 50%, 46.1%, 73% and 57.7%, respectively. Thus, comparing the non-OLP groups with the OLP groups, the periodontopathogens' percentages of detection in the OLP groups were higher than those in the non-OLP groups. According to our study results, OLP patients have higher levels of infection with A. actinomycetemcomitans, P. gingivalis, P. intermedia, T. forsythia and T. denticola than non-OLP patients. We argue that the high percentages in patients with OLP may help identify the importance of periodontopathogenic microorganisms in the progress of periodontal diseases of OLP.

Nurse faculty enrichment and competency development in oral-systemic health

Nurses are positioned to play a significant role in oral health promotion and disease prevention across the life cycle. Oral health has not been a high priority in nursing practice, and educating nurses about oral health has been inadequate particularly regarding the interrelationship between oral health and overall health. The first step for developing a nursing workforce with core competencies in oral health promotion and disease prevention is to prepare nurse faculty with the requisite knowledge, skills, attitudes, and best practices in oral-systemic health. The purpose of this paper is to present Smiles for Life: A National Oral Health Curriculum as a knowledge framework that nurse faculty can use for faculty enrichment and competency development in oral health across the life cycle. A variety of teaching-learning strategies and resources are provided to assist nurse faculty with integrating oral-systemic health into existing nursing curricula.

Application of the theory of planned behavior to nurse practitioners' understanding of the periodontal disease-systemic link

BACKGROUND

Mounting evidence supports a connection between periodontal disease and coronary heart disease, ischemic stroke, and diabetes. This theoretically grounded study examines the knowledge, attitudes, and screening and referral behaviors of primary care nurse practitioners (NPs) in relation to the periodontal disease-systemic link.

METHODS

A questionnaire based on the theory of planned behavior was administered to 200 primary medical care providers, mostly NPs, to determine their practice behaviors, attitudes, opinions, and knowledge regarding the periodontal disease-systemic link. A total of 137 partially and fully complete questionnaires were used for data analyses. Data were analyzed for the reported frequency of screening for periodontal disease and the knowledge of the relationship between periodontal and systemic disease. Oblimin rotation was used to explore the underlying factor structure of 10 practice-behavior items. Bivariate analyses were conducted to determine which factor subscales and demographic characteristics were significantly associated with screening and referral behaviors.

RESULTS

Twenty-two percent of the respondents reported that they always or routinely screened patients for periodontal disease. When providers felt good about their training and continuing education (attitude), they were significantly more likely to screen patients for periodontal disease. If providers believed it was within their scope of practice (social norm) to screen for periodontal disease, and they had control over the establishment of office protocols (control), the likelihood of screening for periodontal disease increased.

CONCLUSIONS

Professional and social norms, the perceived control over one's practice site, and reimbursement were significantly related to NPs engaging in periodontal screening and the subsequent referral for care. These results support the importance of interprofessional and collaborative education between medicine/nursing and dentistry.

Oral health knowledge and behavior among adults with diabetes

The purpose of this study was to determine levels of oral health knowledge and factors associated with adequate oral health knowledge in adults with diabetes. A convenience sample of 253 adult US residents with diabetes completed an oral health survey to assess their knowledge. Results showed that only 47% of the participants answered five or more (out of a maximum of seven) oral health knowledge items related to diabetes correctly. Participants who received oral health information related to diabetes have 2.9 times the odds of possessing adequate oral health knowledge (i.e., answered five or more items correctly) compared to participants who did not received that information controlling for education and race (OR=2.86, 95% CI 1.31-6.24, P=0.008). Given that oral health information provided by health professionals (dental and/or medical) contributes to improve oral health knowledge among adults with diabetes, health professionals should take the opportunity to educate patients with diabetes about the oral manifestations (e.g., dry mouth) and complications (e.g., periodontitis and oral candidiasis) of diabetes and to promote proper oral health behaviors.
