Teaching Silver Diamine Fluoride in U.S. Dental Schools' Predoctoral Curricula

Teaching of silver diamine fluoride for the management of dental caries and hypersensitivity - situation in the Southeast Asia dental schools

BACKGROUND

Using silver diamine fluoride (SDF) for caries management has raised dentists' interests in Southeast Asia (SEA). However, information about the teaching of SDF in dental schools in SEA is limited. Therefore, this survey aimed to describe the extent to which SDF had been introduced into the education of undergraduate students in the dental schools in SEA.

METHODS

An online questionnaire survey was conducted on the duration, method, contents, and barriers regarding the teaching of SDF. Teachers in charge of undergraduate program in pediatric dentistry and those in community dentistry in all the 90 dental schools in SEA were approached and we required each department to reply once only. Descriptive statistics and Chi-square test were used to describe and assess the differences between the two departments in the teaching of SDF.

RESULTS

A total of 81 responses from the departments of 49 schools were received, giving a school-level response rate of 54% (49/90). SDF was taught in the undergraduate program in 86% (42/49) of the respondent schools, and 50% (21/42) of these schools had included SDF in the teaching for five or more years. Almost all (98%) of the departments taught SDF through lectures. Furthermore, 55% of them adopted SDF in clinical practice. Regarding the teaching content, the use of SDF for arresting cavitated caries lesion was the most commonly covered (82-97%), followed by for arresting early noncavitated lesions (69-82%), for preventing new caries development (66-79%) and for treating dental hypersensitivity (77%). There were variations in the post-treatment instruction taught. For the departments not teaching SDF, the most common reason (10/19, 53%) was that SDF was not available.

CONCLUSION

SDF is covered in the undergraduate program in most of the dental schools in SEA. The use of SDF to arrest cavitated caries lesions in primary teeth is usually taught. However, other applications of SDF, such as for prevention of caries and treatment of dental hypersensitivity, are less commonly mentioned in the teaching.

Annual review of selected scientific literature: A report of the Committee on Scientific Investigation of the American Academy of Restorative Dentistry

The Scientific Investigation Committee of the American Academy of Restorative Dentistry offers this review of the 2022 dental literature to briefly touch on several topics of interest to modern restorative dentistry. Each committee member brings discipline-specific expertise in their subject areas that include (in order of the appearance in this report): prosthodontics; periodontics, alveolar bone, and peri-implant tissues; dental materials and therapeutics; occlusion and temporomandibular disorders; sleep-related breathing disorders; oral medicine and oral and maxillofacial surgery; and dental caries and cariology. The authors focused their efforts on reporting information likely to influence the daily dental treatment decisions of the reader with an emphasis on innovations, new materials and processes, and future trends in dentistry. With the tremendous volume of literature published daily in dentistry and related disciplines, this review cannot be comprehensive. Instead, its purpose is to update interested readers and provide valuable resource material for those willing to subsequently pursue greater detail on their own. Our intent remains to assist colleagues in navigating the tremendous volume of newly minted information produced annually. Finally, we hope that readers find this work helpful in managing patients.

Assessment of Sodium Diamine Fluoride (SDF) with Light Curing Technique: A Pilot Study of Antimicrobial Effects

Silver diamine fluoride (SDF) has been useful in clinical dentistry for the purpose of caries arrest and prevention. Although methods for the application of SDF are well-known among dental professionals, such as microbrush applications, few studies have explored the effect of light curing, which accelerates precipitation onto dentin, and whether this has any effect on the antimicrobial properties of SDF. To assess this technique, single (Streptococcus gordonii) and polymicrobial (mixed salivary) colonies were grown and plated using SDF applied to hydroxyapatite discs with and without treatment with curing light. Kirby-Bauer Zone of Inhibition assay results revealed no significant differences in the areas between the two treatment groups (SDF: 1.27 mm, SDF plus curing light: 1.25 mm), p = 0.887 in the single culture (S. gordonii) experiments. In addition, no significant differences were found between the two treatment groups (SDF: 1.26 mm, SDF plus curing light: 1.24 mm), p = 0.771 in the polymicrobial culture experiments. Although there may be specific properties associated with SDF induced following light curing, these differences do not appear to be associated with the antimicrobial properties affecting gram-positive or polymicrobial films.

Crossing the Innovation Chasm: Identifying Facilitators and Barriers to Early Adoption of the Global Health Starter Kit Curriculum

Purpose:

The Global Health Starter Kit (GHSK) is an interdisciplinary, competency-based, open access global health curriculum covering global disease and demographic trends, Millennium Development Goals (MDGs) and Sustainable Development Goals (SDGs), the connection between oral health and overall health, social determinants of health, and concepts of sustainable and ethical global health programs. In this study, we evaluate and describe barriers to and facilitators for using and implementing the GHSK curriculum across a variety of new users.

Methods:

This two-phase study uses the Roger’s Adoption Curve concept to standardize this evaluation and inform a strategic plan for continuing to move the curriculum across the chasm from early adopters to an early majority of global oral health educators and learners. We utilized a theoretical adoption framework to identify facilitators and barriers under the domains of innovation and curricular, educator and learner, and institutional and structural factors. Under qualitative Phase 1, five early adopter institutions were interviewed to elicit understanding of factors that contribute to adoption of the GHSK curriculum. Common themes identified were next used to create a Phase 2 quantitative survey for early majority subscribers of the GHSK (N = 27).

Results:

These qualitative and quantitative results showed an overall high satisfaction with the quality of the GHSK materials, but also effectively identified barriers to its adoption, including inexperience of faculty in teaching global oral health, a lack of awareness and marketing, and absence of global health accrediting requirements.

Conclusions:

By identifying the barriers and facilitators of GHSK curriculum integration, this study provides concrete and specific opportunities to improve its format, relevance, content, and delivery. This study outlines next steps to creating a standardized approach to successfully adopting competency-based global oral health teaching and learning.

Teaching Minimally Invasive Interventions in Paediatric Dentistry: A Cross-Sectional Survey of Dental Schools in Iran

BACKGROUND

Dental caries is a significant public health problem in Iran. Teaching  minimally invasive interventions in paediatric dentistry may facilitate the provision of treatment for untreated dental caries in children. We evaluated the teaching of such interventions in both undergraduate dental curriculum and Paediatric Dentistry Specialty Training Programme (PDSTP) in Iran.

METHODS

This was a cross-sectional questionnaire-based survey. Participants in this study were the directors of 40 undergraduate programmes and 15 PDSTPs in all Iranian dental schools (response rate = 100%). Descriptive statistics were reported.

RESULTS

The most commonly taught methods were preventive fissure sealant and preventive resin restoration (PRR), which were taught 'both didactically and clinically' in all undergraduate dental programmes. The least commonly taught methods were silver diamine fluoride (SDF), the Hall technique and resin infiltration, which were taught 'both didactically and clinically' in less than 5% of dental schools. The same three methods were the least commonly approaches taught in PDSTP, further, they were less often perceived to be 'essential'.

CONCLUSIONS

There was a notable variation in the teaching of the management of dental caries in Iran's dental education. Some minimally invasive approaches including SDF, the Hall technique and resin infiltration are not being commonly taught in Iranian dental schools despite the evidence base for these techniques.

Assessment of knowledge and perception about silver diamine fluoride (SDF) for treating older adults among graduating dental students

PURPOSE/OBJECTIVES

Silver diamine fluoride (SDF) is a promising therapy for arresting and preventing caries in difficult to treat, high-risk populations, including institutionalized older adults. This study investigates the knowledge and perceptions about SDF of graduating dental students in multiple U.S. dental schools, as well as their willingness to use SDF in their practices.

METHODS

A survey was designed consisting of 21 total questions: 6 questions regarding students' demographic information and their SDF content exposure contextualization, 8 questions tailored to investigate 2 domains regarding students' knowledge about SDF (properties and indication), and 7 questions aiming to investigate 3 domains regarding students' perceptions about SDF (SDF usefulness, appropriateness of using SDF, and willingness to use SDF when in private practice). The survey was then distributed to graduating dental students at 7 U.S. dental schools.

RESULTS

A total of 386 surveys (response rate of 55%) was collected from 7 schools in the Spring of 2019. The median score resulting from the SDF content exposure questions was 3 (SD = 1.43) from a range of 0-5. The median score from knowledge about SDF properties was 4 (SD = 1.18) from a range of 0 to 6. In the multivariate analysis, a linear model found that the covariates "SDF Usefulness", "SDF Appropriateness" and "SDF Patient Willingness to Use" were significantly associated with higher student willingness to use SDF (R²  = 0.395).

CONCLUSION

The results indicated that the graduating students have a positive perception of SDF regarding its usefulness and appropriateness. Graduating students appear inclined to utilize SDF upon entering private practice.

Dentists' Adoption of Silver Diamine Fluoride among 1- to 5-Year-Old Children in North Carolina

BACKGROUND

A natural experiment was conducted to observe the adoption of silver diamine fluoride (SDF) by Medicaid-enrolled dentists in North Carolina (NC). The purpose of this study was to describe the sociocontextual and community health characteristics where dentists adopted SDF, determine the association between SDF use and general anesthesia (GA) use, and examine the changes in GA utilization following implementing SDF reimbursement.

METHODS

NC Medicaid initiated SDF reimbursement in 2016 for children ages 1 to 5 y. This cross-sectional time series study used aggregate NC Medicaid claims, including geographic data, from 2014 to 2018. All dentists who provided GA and/or SDF to children ages 1 to 5 y were included. County health ranking data described social and community health indicators. Descriptive statistics, spatial data techniques, and multivariable methods were used.

RESULTS

From 2016 to 2018, the number of dentists using SDF increased from 35 to 258, or 637%, whereas the number of dentists using GA increased from 179 to 211, or 17%. SDF utilization spread outward from areas of good social and health indicators to areas of poorer indicators. SDF utilization increased from 0.35 to 0.65 per 1,000 children, whereas GA utilization decreased from 2.57 to 2.47 per 1,000 children. GA utilization was positively associated with SDF utilization and poorer county health ranking but did not change before and after SDF implementation.

CONCLUSION

Early adopters of SDF in NC practiced in areas with positive social and community health indicators. Over time, SDF was adopted in resource-poor communities. It remains too early to determine the public health impacts of SDF treatment on GA utilization.

KNOWLEDGE TRANSFER STATEMENT

Policy makers and clinicians can use the results of this study to develop geographically targeted interventions that could lead to clinically and cost-effective public health programs.
