Using Interprofessional Education to Promote Oral Health Literacy in a Faculty-Student Collaborative Practice.

The aim of this study was to assess the oral health literacy knowledge gained by patients who are refugees, community members, and medical and nursing students after participating in an interprofessional education collaborative of students and faculty from the University of Texas Health San Antonio Schools of Dentistry, Medicine, and Nursing. In this faculty-student collaborative practice, all patients were triaged (including oral hygiene status and alcohol/tobacco use), and tailored treatment options were offered following assessment of their dental, medical, and social histories. The study was designed as a pre-post assessment of an educational intervention on oral health literacy. In the pretest, all groups were invited to respond to questionnaires assessing their knowledge of oral health. After participants engaged in oral hygiene instruction demonstrations and received information about an oral health literacy campaign, a posttest was conducted to assess knowledge gained. A total of 151 patients who were refugees, 38 medical students, 34 nursing students, and 17 community/parish members voluntarily participated in this initiative. Each group had a significant increase in mean oral health literacy score from pre- to posttest: patients 33.5%, community/parish members 22.3%, nursing students 20.8%, and medical students 13% (all p<0.0001). These results showed that the oral health literacy initiative helped increase all participants' oral health literacy and knowledge of preventive care.

Visual scoring of non cavitated caries lesions and clinical trial efficiency, testing xylitol in caries-active adults.

OBJECTIVES: To better understand the effectiveness of xylitol in caries prevention in adults and to attempt improved clinical trial efficiency. METHODS: As part of the Xylitol for Adult Caries Trial (X-ACT), non cavitated and cavitated caries lesions were assessed in subjects who were experiencing the disease. The trial was a test of the effectiveness of 5 g/day of xylitol, consumed by dissolving in the mouth five 1 g lozenges spaced across each day, compared with a sucralose placebo. For this analysis, seeking trial efficiency, 538 subjects aged 21-80, with complete data for four dental examinations, were selected from the 691 randomized into the 3-year trial, conducted at three sites. Acceptable inter- and intra-examiner reliability before and during the trial was quantified using the kappa statistic. RESULTS: The mean annualized noncavitated plus cavitated lesion transition scores in coronal and root surfaces, from sound to carious favoured xylitol over placebo, during the three cumulative periods of 12, 24, and 33 months, but these clinically and statistically nonsignificant differences declined in magnitude over time. Restricting the present assessment to those subjects with a higher baseline lifetime caries experience showed possible but inconsistent benefit. CONCLUSIONS: There was no clear and clinically relevant preventive effect of xylitol on caries in adults with adequate fluoride exposure when non cavitated plus cavitated lesions were assessed. This conformed to the X-ACT trial result assessing cavitated lesions. Including non cavitated lesion assessment in this full-scale, placebo-controlled, multisite, randomized, double-blinded clinical trial in adults experiencing dental caries did not achieve added trial efficiency or demonstrate practical benefit of xylitol.

Clinical evaluation of an enhanced white light and fluorescence device for early detection of caries lesions.

OBJECTIVE: Sensitivity of a device based on Fluorescence Imaging with Reflectance Enhancement (FIRE) in detecting a potential incipient lesion (PIL) was compared with visual examination to demonstrate non-inferiority to it. METHODS: Visual examination (VE) and an investigational device (ID) were used to detect PIL (actual incipient caries [AIC] and hypomineralization). Seventeen subjects satisfied data analysis criteria. Two-hundred and seventy-seven AIC and 367 hypomineralizations reached VE consensus. Ground truth was generated from consensus VE results and image information from enhanced white light (eWL) and FIRE images. Data from VE and ID in Still Image (IDSM) and Video (IDVM) modes were evaluated against ground truth. RESULTS: Overall sensitivity of VE, IDSM, and IDVM evaluated against ground truth were 0.94, 0.884, and 0.848, respectively, for Actual Incipient Caries (AIC) detection, and 0.95, 0.916, and 0.883, respectively, for PIL detection. Sensitivity of ID in both modes was > 90% that of VE, thus demonstrating non-inferiority of IDSM and IDVM to VE. CONCLUSION: The investigated eWL and fluorescence device is clinically effective and at least as good as expert VE in detecting PIL. An enhanced white light device with FIRE technology can be used, in Video or Still Image Detection modes, as an aid to caries diagnosis.

Rethinking tenure in dental education.

In the midst of changes in the environment of academic dentistry over the past two decades, reform of traditional tenure is one way for dental schools to respond to these changes while maintaining scholarly, evidence-based learning environments. Challenges facing academic dentistry today and in the future include a crisis in workforce capacity, difficulty attracting recent graduates into academic positions, overburdened faculty members with limited time for scholarly activity, loss of tenured faculty members due to retirement, and a potentially diminished voice for dental schools within the parent university. The purpose of this opinion article is to suggest ways to reform the current tenure system in dental education as a means of improving recruitment and retention of new faculty members while maintaining or increasing scholarly activity within dental schools.
