Dental Caries (Cavities): Community-Based Initiatives to Promote the Use of Dental Sealants

Summary of CPSTF Finding

The Community Preventive Services Task Force (CPSTF) finds insufficient evidence to determine the effectiveness of community-based initiatives to promote use of dental sealants. Although strong evidence exists for the efficacy of sealants and their delivery through school-based programs for preventing caries (tooth decay), few studies examined uptake of sealants following community-based promotion initiatives and their results were inconsistent.

Intervention

Community-based dental sealant promotion initiatives aim to increase sealant use, especially among specific populations at high risk for tooth decay (e.g. low-income).

These initiatives can take many forms including continuing education courses for dental professionals; educational campaigns for parents, community leaders, or third party payers of dental treatment; policies to promote access to sealants; financial incentives or reimbursement; and promotional activities to increase the number of schools with sealant delivery programs and the number of students participating in these programs.

School-based sealant delivery programs, which are distinct from community-based initiatives to promote use of sealants, have been recommended by CPSTF based on strong evidence of effectiveness in preventing tooth decay among children.

A meta-analysis (Ahovuo-Saloranta et al., 2013) has shown that dental (pit and fissure) sealants prevent caries (tooth decay) in children and adolescents by 81% at 2 year follow-up. Sealants are clear or opaque plastic resinous materials applied to the chewing surfaces of the back teeth to prevent tooth decay. Despite their effectiveness, sealant use remains low, especially among children from low-income families and certain racial or ethnic groups.

About The Systematic Review

The CPSTF finding is based on evidence from a systematic review of three studies (search period 1946-2012). The systematic review was conducted on behalf of the CPSTF by a team of specialists in systematic review methods, and in research, practice, and policy related to oral health. This finding updates and replaces the 2000 review on Statewide or Community-Wide Sealant Promotion.

Summary of Results

Included studies evaluated interventions that used education, mass media, financial incentives, or a combination of these methods.

  • One intervention offered financial incentives to dental health professionals and saw a significant 9.8 percentage point increase in the number of children who received sealants.
  • Neither education (2 study arms) nor mass media (1 study) showed significant effects on sealant use.

Summary of Economic Evidence

An economic review of this intervention was not conducted because CPSTF did not have enough information to determine if the intervention works.

Applicability

Applicability of this intervention across different settings and populations was not assessed because CPSTF did not have enough information to determine if the intervention works.

Evidence Gaps

CPSTF identified several areas that have limited information. Additional research and evaluation could help answer the following questions and fill remaining gaps in the evidence base. (What are evidence gaps?)

  • More evidence is needed to assess the effectiveness of community-based sealant promotion initiatives for increasing sealant use.
  • Additionally, research should be done to better understand dental health professionals’ beliefs and other barriers that prevent change with regard to sealant application.

Study Characteristics

  • Included evidence comes from the United States (2 studies) and the United Kingdom (1 study).
  • Studies reported the percentage of children who received sealants, the number of sealants applied per child, and the extent of sealant use among dentists.

Analytic Framework

Effectiveness Review

Analytic Framework

When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

Search Strategies

Four bibliographic databases were searched: OHG Register, CENTRAL, MEDLINE, and EMBASE. The databases searched covered publications in biomedical and behavioral sciences. Search strategies were adjusted to each database, based on controlled and uncontrolled vocabularies and search software. The types of documents searched in the databases included journal articles, books, book chapters, reports, conference papers, and dissertations. In addition, the bibliographies of all reviewed articles were used to identify any further literature.

Considerations for Implementation

CPSTF did not have enough evidence to determine whether the intervention is or is not effective. This does not mean that the intervention does not work, but rather that additional research is needed to determine whether or not the intervention is effective.

Other evidence-based interventions such as school-based sealant delivery programs should be considered when making decisions about potential ways to increase sealant use.
