Barriers to sealant guideline implementation within a multi-site managed care dental practice

Adoption and Effect of Sealants for Occlusal Noncavitated Caries in a Large Dental Network in the USA

INTRODUCTION

Dental sealants applied to occlusal pit-and-fissure surfaces have been shown to prevent caries and arrest occlusal noncavitated carious lesions (NCCLs). The American Dental Association (ADA) recommends that oral healthcare providers apply sealants on occlusal NCCLs. Though the evidence is clear that sealants are effective, few studies have examined the adoption of the ADA guideline by dentists and the duration of protection provided by sealants in a large real-world setting.

METHODS

This study used observational electronic health record (EHR) data from a network of dental clinics to follow teeth over a 2 year time period from when they were diagnosed as having an occlusal NCCL until either they were treated with a restoration or the time period ended with no restoration. The objectives of the study were to determine: (1) the degree to which dentists adopted the guideline, (2) whether the duration of protection was different for teeth that received a sealant from teeth that did not receive a sealant, and (3) whether dentists' experience placing sealants was associated with the duration of protection.

RESULTS

Overall, there were 7,299 teeth in the sample. Of those, dentists restored 591 teeth and applied sealants on 164. The sealant application rate for eligible teeth was 2.2%. Sealant application was associated with provider, with 1.9% of providers placing more than half of the sealants. By the end of the observation period, the proportion of teeth progressing to restorations was 8.2% for teeth that had not received a sealant and 3.0% for teeth that had received one (RR = 0.37; 95% CI: 0.16-0.88; p = 0.02). Multilevel survival analysis showed that teeth that had not received a sealant were restored sooner than teeth that had received a sealant (aHR = 0.11; 95% CI: 0.03-0.36; p < 0.01). Overall, teeth that received a sealant had an 89% reduced hazard of restoration within 2 years compared with teeth that did not receive sealants.

CONCLUSION

This study found that by arresting decay, the presence of sealants led to fewer restorations and delayed restorations compared with teeth not receiving a sealant or restoration in the 2 years following diagnosis of occlusal NCCL in clinical settings.

Improvements in appropriate placement of dental sealants after implementation of a clinical decision support system

BACKGROUND

Dental sealants are effective for the prevention of caries in children at elevated risk levels, and increasing the proportion of children and adolescents who have dental sealants on 1 or more molars is a Healthy People 2030 objective. Electronic health record (EHR)-based clinical decision support systems (CDSSs) have the ability to improve patient care. A dental quality measure related to dental sealant placement for children at elevated risk of caries was targeted for improvement using a CDSS.

METHODS

A validated dental quality measure was adapted to assess a patient's need for dental sealant placement. A CDSS was implemented to advise care team members whether a child was at elevated risk of developing caries and had sealant-eligible first or second molars. Data on dental sealant placement at examination visits during a 5-year period were analyzed, including 32 months before CDSS implementation and 28 months after CDSS implementation.

RESULTS

From January 1, 2018, through December 31, 2022, the authors assessed 59,047 examination visits for children at elevated risk of developing caries and with sealant-eligible teeth. With the implementation of a CDSS and training to support the clinical care team members in September 2020, the appropriate placement of dental sealants at examination visits increased from 27% through 60% (P < .00001).

CONCLUSIONS

Integration of a CDSS into the EHR as part of a quality improvement program was effective in increasing the delivery of sealants in eligible first and second molars of children aged 5 through 15 years and considered at high risk of developing caries.

PRACTICAL IMPLICATIONS

An EHR-based CDSS can be implemented to improve standardization and provide timely and appropriate patient care in dental practices.

Study protocol: A stepped-wedge, cluster-randomized trial of the effectiveness of a deliberative loop in identifying implementation strategies for the adoption of a dental sealant guideline in dental clinics

BACKGROUND

The American Dental Association (ADA) recommends dental providers apply dental sealants to the occlusal surfaces of permanent molars for the prevention or treatment of non-cavitated dental caries. Despite the evidence-based support for this guideline, adherence among general dentists is low, ranging from less than 5 to 38.5%. Thus, an evidence-to-practice gap exists, and it is unclear which implementation strategies would best support providers in adopting and implementing the evidence-based practice. One potential approach to selecting and tailoring implementation strategies is a deliberative loop process, a stakeholder-engaged approach to decision-making. This trial aims to test the acceptability, feasibility, and effectiveness of using a deliberative loop intervention with stakeholders (i.e., providers and staff) to enable managers to select implementation strategies that facilitate the adoption of an evidence-based dental practice.

METHODS

Sixteen dental clinics within Kaiser Permanente Northwest Dental will be cluster randomized to determine the timing of receiving the intervention in this stepped-wedge trial. In the three-part deliberative loop intervention, clinic stakeholders engage in the following activities: (1) receive background information, (2) participate in facilitated small-group discussions designed to promote learning from each other's lived experiences and develop informed opinions about effective clinic-level implementation strategies, and (3) share their informed opinions with clinic leaders, who may then choose to select and deploy implementation strategies based on the stakeholders' informed opinions. The primary outcome of Reach will be defined as patient-level receipt of guideline-concordant care. Secondary outcomes will include the cost-effectiveness, acceptability, and feasibility of the deliberative loop process. Implementation strategies deployed will be catalogued over time.

DISCUSSION

These results will establish the extent to which the deliberative loop process can help leaders select and tailor implementation strategies with the goal of improving guideline-concordant dental care.

Ion release and recharge from a fissure sealant containing amorphous calcium phosphate

To assess- the release of calcium and phosphate ions from a fissure sealant containing amorphous calcium phosphate (ACP), and to determine the re-release capacity of these ions when charged with a solution containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP). Nine blocks of ACP resin-based sealant were prepared and immersed in three solutions at different pH (4.0, 5.5, 7.0), and calcium and phosphate ion release was measured with ion chromatography at 1, 3, 5, 7, 14, 21 and 28 days after immersion. Sixty days after immersion, each block was charged with CPP-ACP solution in three 7-day cycles to investigate the re-release of these ions, which was measured on days 1, 3, and 7. No difference was observed in initial calcium ion release at pH 4.0 and pH 5.5. At both values, ion release was significantly higher than at pH 7.0 (p<0.001). Initial phosphate release was significantly different among the three pH values (p<0.001). After re-charging the specimens, calcium ion re-release was greater than phosphate ion release. Initial ion release from ACP resin-based sealant was greatest at the lowest pH. Ion release decreased with time. As the number of recharge cycles increased, ion re-release also improved. Phosphate ion re-release required more recharge cycles than calcium ion re-release.

Measuring sealant placement in children at the dental practice level

Background.

Although sealants are an established and recommended caries-preventive treatment, many children still fail to receive them. In addition, research has shown that existing measures underestimate care by overlooking the sealable potential of teeth before evaluating care. To address this, the authors designed and evaluated 3 novel dental electronic health record–based clinical quality measures that evaluate sealant care only after assessing the sealable potential of teeth.

Methods.

Measure I recorded the proportion of patients with sealable teeth who received sealants. Measure II recorded the proportion of patients who had at least 1 of their sealable teeth sealed. Measure III recorded the proportion of patients who received sealant on all of their sealable teeth.

Results.

On average, 48.1% of 6- through 9-year-old children received 1 or more sealants compared with 32.4% of 10- through 14-year-olds (measure I). The average measure score decreased for patients who received sealants for at least 1 of their sealable teeth (measure II) (43.2% for 6- through 9-year-olds and 28.4% for 10- through 14-year-olds). Fewer children received sealants on all eligible teeth (measure III) (35.5% of 6- through 9-year-olds and 21% of 10- through 14-year-olds received sealant on all eligible teeth). Among the 48.5% who were at elevated caries risk, the sealant rates were higher across all 3 measures.

Conclusions.

A valid and actionable practice-based sealant electronic measure that evaluates sealant treatment among the eligible population, both at the patient level and the tooth level, has been developed.

Practical Implications.

The measure developed in this work provides practices with patient-centered and actionable sealant quality measures that aim to improve oral health outcomes.

Implementation science and periodontal practice: Translation of evidence into periodontology

The advent of evidence-based practice in the 1990s led to the development of processes and resources to support the use of high-quality research in the provision of health care. As the evidence-based approach to health care continues to evolve, it has become apparent that mere creation and access to scientific knowledge is not sufficient to facilitate its routine adoption in health care. Throughout any health care system, there are inherent barriers preventing the adoption and routine use of new evidence in patient care. These barriers include provider-level factors, such as knowledge and access to new evidence, as well as each provider's attitudes and beliefs around adopting and applying the evidence with their patients. Importantly, there are also health care system-level barriers that, even among willing providers, prevent the easy adoption of new evidence and routine application in patient care. In addition to barriers, there are facilitators that help promote adoption of evidence into practice. Understanding and addressing barriers and facilitators to promote adoption of evidence into practice has led to the growth of a new field known as implementation science. Successful application of implementation science in all areas of health care, including periodontology, will help bridge the gap between what are known from clinical research to be effective treatments and what treatments should be applied routinely in clinical practice. This article reviews key concepts in implementation science and how its application in periodontology can facilitate the translation of high-quality evidence into routine periodontal practice and improved patient outcomes.

Stakeholder Assessment of Evidence-Based Guideline Dissemination and Implementation in a Dental Group Practice

OBJECTIVE

This evaluation captures the perspectives of multiple stakeholders within a salaried dental care delivery organization (dentists, dental assistants, dental hygienists, and dental management) on the implementation of a pit-and-fissure sealant guideline in the Kaiser Permanente Dental Program. Also assessed is the role of formal processes and structures in providing a framework for guideline implementation.

METHODS

We collected qualitative data through field observations, stakeholder interviews (n = 6), and focus groups (30 participants in 5 focus groups). Field observation notes captured summaries of conversations and other activities. Interviews and focus groups were recorded and transcribed. We analyzed transcripts and field notes using a template analysis with NVivo 12 software to identify themes related to the existing implementation process of clinical guidelines and stakeholder perspectives on the strengths and weaknesses of this process.

RESULTS

Stakeholders perceived 2 main barriers for achieving implementation of the pit-and-fissure sealant guideline: 1) shortcomings in the implementation infrastructure resulting in lack of clarity about the roles and responsibilities in the guideline implementation process and lack of effective mechanisms to disseminate guideline content and 2) resource constraints, such as limited human, space, and material resources. Perceived opportunities for the dissemination and implementation of guidelines included recognition of the importance of guidelines in dental practice and well-functioning workflows within dental specialties.

CONCLUSION

Our research points to the importance of developing and maintaining an infrastructure to ensure standardized, predictable mechanisms for implementation of guidelines and thereby promoting practice change. While addressing resource constraints may not be possible in all circumstances, an important step for improving guideline implementation-wherever feasible-would be the development of a robust implementation infrastructure that captures and delineates roles and responsibilities of different clinical actors in the guideline implementation process.

KNOWLEDGE TRANSFER STATEMENT

The results of this study can be used by health care leadership and administrators to understand possible reasons for a lack of guideline implementation and provide suggestions for establishing sustainable infrastructure to promote the adoption of clinical guidelines in salaried dental clinics.

The effectiveness of guideline implementation strategies in the dental setting: a systematic review

BACKGROUND

Guideline implementation has been an ongoing challenge in the dental practice setting. Despite this, there are no reviews summarising the existing evidence regarding effective guideline implementation strategies in this setting. In order to address this, this systematic review examines the effectiveness of guideline implementation strategies in the dental practice setting.

METHODS

A systematic search was undertaken according to the PRISMA statement across nine electronic databases, targeting randomised controlled trials and quasi-experimental studies which evaluated the effectiveness of guideline implementation strategies in improving guideline adherence in the dental setting. All records were independently examined for relevance and appraised for study quality by two authors, with consensus achieved by a third author. Data were extracted from included studies using a standardised data extraction pro forma.

RESULTS

A total of 15 records were eligible for inclusion in this review, which focused on the effects of audit and feedback, reminders, education, patient-mediated interventions, pay for performance and multifaceted interventions. Although there were some conflicting evidence, studies within each category of implementation strategy indicated a positive effect on guideline adherence.

CONCLUSIONS

This study has identified education, reminders and multifaceted interventions as effective implementation strategies for the dental practice setting. Although this is similar to research findings from other health sectors, there is some evidence to suggest patient-mediated interventions may be less effective and pay for performance may be more effective in the dental setting. These findings can inform policy makers, professional associations, colleges and organisations in the future adoption of clinical guidelines in the dental practice setting.

Effect of hydroxyapatite nanoparticles on enamel remineralization and estimation of fissure sealant bond strength to remineralized tooth surfaces: an in vitro study

Background

The management of noncavitated caries lesions before sealant therapy is a clinical challenge when the tooth needs sealant application. Sealing noncavitated carious lesions in pits and fissures may lead to failure of the fissure sealant (FS) due to incomplete sealing. Therefore the use of remineralizing agents such as nanoparticles has been suggested. This study investigated the ability of hydroxyapatite nanoparticles (nano-HA) to remineralize enamel, and their effect on sealant microleakage and shear bond strength (SBS).

Methods

A total of 192 third molars were demineralized and pretreated with two concentrations of nano-HA with and without sodium hexametaphosphate (SHMP), followed by phosphoric acid etching and resin FS application. The study groups were 1) etching + FS, 2) etching + nano-HA 0.15% + FS, 3) etching + nano-HA 0.03% + FS, 4) etching + mixture of nano-HA 0.15% and SHMP 0.05% + FS, 5) etching + mixture of nano-HA 0.03% + SHMP 0.01% + FS. The laboratory tests included microleakage in 50 teeth, scanning electron microscopy (SEM) evaluation in 10 samples, and SBS in 100 samples. Enamel remineralization changes were evaluated in 32 teeth with energy-dispersive X-ray spectroscopy (EDS) and field emission scanning electron microscope (FESEM).

Results

Nano-HA enhanced the SBS to remineralized enamel in a large percentage of nanoparticles. Mean SBS in group 2 was significantly greater than in groups 1, 3 and 4 (all P < 0.05). SBS was related to nano-HA concentration: nano-HA 0.15% yielded greater SBS (16.8 ± 2.7) than the 0.03% concentration (14.2 ± 2.1). However, its effect on microleakage was not significant. Nano-HA with or without SHMP led to enhanced enamel remineralization; however, the Calcium (Ca)/Phosphate (P) weight percent values did not differ significantly between the groups (P > 0.05). SEM images showed that SHMP did not affect sealant penetration into the deeper parts of fissures. FESEM images showed that adding SHMP led to increased nanoparticle dispersal on the tooth surface and less cluster formation.

Conclusions

The ultraconservative approach (combining nano-HA 0.15% and SHMP) and FS may be considered a minimal intervention in dentistry to seal demineralized enamel pits and fissures.

Fissure sealants or fluoride varnish? Routines and attitudes among dental health personnel in Norway

PURPOSE

To investigate routines and attitudes among dentists and dental hygienists concerning use of fissure sealants and fluoride varnish for non-operative management of occlusal caries.

METHODS

All dentists and dental hygienists working in child dental care in three counties in Norway were invited to answer a questionnaire on routines for use of fissure sealants and fluoride varnish. Nine statements regarding attitudes towards use of sealants were scored using a five-point Likert scale. Multivariable logistic regression analyses were performed to assess indicators associated with reported routines for use of sealants and varnish. The study was approved by the Norwegian Centre for Research Data.

RESULTS

In total 142 of 189 (75%) dentists and dental hygienists answered the questionnaire. The majority of the respondents, n = 83 (59%), reported to prefer fissure sealants while fluoride varnish was preferred by 57 (41%) of the respondents. Frequent use of fissure sealants was reported by 58 (41%) and frequent use of varnish by 104 (74%) of the respondents. Most (n = 104, 74%), used sealants on specific indications, and 89 (64%) opened fissures only when suspecting dentine caries. Preferred method and routines for occlusal caries management differed between counties (p < 0.05). Almost all clinicians agreed with the statement that sealants are protective against caries, while statements regarding costs, technique sensitivity and children's cooperation revealed some concerns regarding fissure sealing.

CONCLUSIONS

Fissure sealants were the preferred method for occlusal caries management despite reported concerns related to technical aspects and patient cooperation. County-level variation in frequency of sealant use was observed.

Translational Research: Bringing Science to the Provider Through Guideline Implementation

Significant variation exists in health care practice patterns that creates concerns regarding the quality of care delivered. Clinical practice based on high-quality evidence provides a rationale for clinical decision making. Resources, such as evidence-based guidelines, provide that evidence to clinicians and improve patient outcomes by decreasing unwanted variation in clinical practice. Because knowledge dissemination alone is ineffective to translate scientific evidence into clinical practice, the field of implementation science has emerged to facilitate this translation of research into routine clinical practice. This article provides an introduction to implementation science, and its application in dentistry to promote adoption of evidence-based guidelines.

Trends in First-Year Dental Students' Information Technology Knowledge and Use: Results from a U.S. Dental School in 2009, 2012, and 2017

Dental students must be skilled in the use and application of information technology (IT), but there are few studies of IT use and knowledge among U.S. dental students. The aim of this study was to retrospectively analyze survey data regarding IT use and knowledge collected from first-year dental students at one U.S. dental school in 2009, 2012, and 2017. Data were collected from an anonymous survey of these students as part of a D1 course called Informatics and Evaluation of Dental Literature. All students participated in the survey each year, for a response rate of 100%. Annual numbers of participants were 80 (2009), 90 (2012), and 97 (2017), for a total 267 respondents. The students reported that they frequently accessed Internet resources multiple times per day and that frequency of use had increased over time, principally from access via smartphones. These students reported feeling comfortable with higher education IT applications such as learning management systems and computerized testing. However, despite their frequent IT use, the students reported low levels of knowledge about IT security, and the three years of survey data showed that IT security knowledge had declined over time. These findings have implications for dental educators, including the need for methods for training students to protect their personal data and that of their patients.

Silver diamine fluoride versus therapeutic sealants for the arrest and prevention of dental caries in low-income minority children: study protocol for a cluster randomized controlled trial

BACKGROUND

Dental caries is the most prominent childhood disease in the world. In the United States, more than 50% of children have experienced caries. Untreated caries can have negative impacts on quality of life, academic performance, and school attendance. To reduce oral health disparities, multiple organizations recommend school-based caries prevention.

METHODS/DESIGN

A longitudinal, cluster randomized, non-inferiority trial will be conducted in low-income children from primarily Hispanic/Latino backgrounds currently enrolled in public elementary schools in New York City, New York, United States, from 2018 to 2023. The primary objective is to compare the non-inferiority of silver diamine fluoride and fluoride varnish versus glass ionomer therapeutic sealants and fluoride varnish in the arrest and prevention of dental caries. Secondary objectives are to evaluate differences in effectiveness when care is provided by nurses versus dental hygienists and assess the impact of prevention on oral health-related quality of life and educational outcomes. Caries arrest will be evaluated after 2 years, and caries prevention and secondary outcomes will be assessed at the completion of the study. Data analysis will follow intent-to-treat, and statistical analyses will be conducted using a two-sided significance level of 0.05.

DISCUSSION

The comparative effectiveness of alternative caries prevention delivery models is considered to be one of the highest research priorities in the United States. Many treatments are currently available to prevent and arrest dental caries. The simplicity and affordability of silver diamine fluoride may be a viable alternative for the prevention of dental caries in high-risk children.
