Fissure Sealants or Fluoride Varnish? A Randomized Pragmatic Split-Mouth Trial

This study aimed to compare the clinical effectiveness of resin-based fissure sealants (FS) and fluoride varnish (FV) in children at high caries risk. A practice-based split-mouth randomized clinical trial was conducted at 9 Public Dental Service (PDS) clinics in Norway. In total, 409 children age 6 to 10 y at high caries risk (d3mft > 0) meeting inclusion criteria were recruited by dentists and dental hygienists during routine examination. Eligibility criteria were 2 fully erupted first permanent molars (FPMs) in the same jaw, with sound occlusal surfaces or with initial caries. Participation was voluntary, caregivers and eligible children were informed about the study, and written parental consent was obtained. FS and FV were randomly applied on contralateral FPMs in the same jaw, with each participant serving as their own control. FS was applied at baseline and thereafter maintained according to clinicians' conventional procedures, whereas FV was applied at baseline, 6 mo, and 12 mo. The study outcome was success, with no need for invasive treatment (caries control), while failure was defined as dentin carious lesion or restoration. Two-level mixed-effects logistic regression analysis was used to compare FS and FV groups. Of 409 recruited children, 369 (90%) children/tooth pairs were examined after 36 mo. Intention-to-treat analysis showed 94.1% adjusted predicted probability (aPP) of success (95% confidence interval [CI] 91.7 to 96.4) in the FS group and 89.6% aPP (95% CI 86.5 to 92.7) in the FV group. In the adjusted analysis, the FV group had a lower OR for success compared with the FS group (OR 0.54, 95% CI 0.24 to 0.87). In the population studied, the clinical effectiveness of FS was statistically significantly higher compared with FV but below the estimated minimal clinically important difference of 10%.

Fissure sealant therapy as a portable community-based care in deprived regions: Effectiveness of a clinical trial after 1 year follow-up

The aim of this study was to evaluate the effectiveness of the fissure sealant therapy in suboptimal setting (as part of a community-based program using the portable equipment and provided by dental students) on the caries status of school children. This pragmatic split-mouth randomised clinical trial was conducted in rural area of Iran. At baseline, 124 patients, including 185 paired teeth with deep pits and fissures of opposite quadrants that were either healthy or at early stages of enamel decay (International Caries Detection and Assessment System [ICDAS] 0-2), were randomly allocated to receive fissure sealant or acted as control. The incidence of new caries (ICDAS code 3-6) and the sealant's retention status after 1-year follow-up were evaluated. Using chi-square test, the relative risk (RR) and the Number Needed to Treat (NNT) to prevent new caries were calculated. After 1 year, 109 patients including 163 paired teeth were available. Sixty-seven (41.4%) and 44 (27.2%) teeth had complete and partial retained sealants respectively. The risk of caries incidence in non-sealed teeth was almost three times more than sealed teeth (RR = 2.88, 95% CI: 1.4-1.97, p = 0.002) and the NNT was 10 (95% CI: 6-26). A significant association was noted between the status of sealant retention after 1 year and the incidence of new caries (p < 0.001). Fissure sealant as part of a community-based program was effective in controlling caries incidence.

Demonstration of payer readiness for value-based care in a fee-for-service environment: Measuring provider performance on sealant delivery

OBJECTIVES

Previously published sealant measures are not useful when applied to Medicaid claims data in states where dental services are carved out of managed care. A novel sealant measure was developed to assess the degree to which dental providers seal eligible teeth during preventive dental visits (PDVs) in an effort to ascertain if such a measure can be used to valuate provider performance, as condition of potential value-based care model implementation.

METHODS

A single-county feasibility study was conducted using Medicaid claims. A study cohort included children aged 8 years and enrolled 12 months during 2018. Prospective analysis was used to determine whether dental sealants were applied by the same dentists during PDVs or up to 9 months thereafter. Eligible teeth included first permanent molars. Teeth previously restored, sealed or missing were excluded. PDV was defined as any encounter with prophylaxis, fluoride treatment, or EPSDT. Claims were compared to public health surveillance for measurement validation.

RESULTS

Single-county results showed 11 percent of eligible teeth were sealed. Only 9 percent of dentists applied sealants to at least 40 percent of eligible teeth. Face validation of sealant rate was 23 percent Medicaid versus 36 percent Public Health. The former measures incidence and the latter prevalence with greater heterogeneity that included partially retained sealants.

CONCLUSIONS

A sealant measure that assesses provider adherence to sealant standards of care was produced. It has potential application for assessing performance of pediatric preventive services and informing value-based performance expectations.

A scoping review on social justice education in current undergraduate dental curricula

BACKGROUND

A recent shift in educational components within healthcare has pushed dentistry toward a greater understanding of the role of social components on oral health. There has also been an increased awareness of inappropriate conduct among dental students.

STUDY DESIGN AND METHODS

A scoping review was conducted to determine if, how, and when social-justice-oriented education has been incorporated into dental curricula worldwide. A systematic and reiterative search of articles was performed on February 22, 2018, and combined quantitative and qualitative synthesis of data. An updated search was done on September 26, 2019.

PRIMARY RESULTS

Seventy-three studies were evaluated: 46 quantitative (63%), 24 qualitative (33%), 3 multimethods (4%). The majority used self-reported surveys and questionnaires (66%), while the remaining used interviews (9.5%), student reflections (16%) and focus groups (5.5%). Studies included dental students only (78%); dental students with dental hygiene students (5.5%) or faculty/staff (4.1%); dental students in year 1 (17%), year 2 (1.6%), year 3 (1.6%), year 4 (14.2%); first- and second-year students (3%); third- and fourth-year students (1.6%); all years of study (20%); and academic year not specified (41%). The study areas included "learning in dental school," "experiencing dental school," "focusing on cultural competency," and "addressing dental ethics and social responsibility."

PRINCIPAL CONCLUSIONS

Three major research gaps were identified: no discussion of a social contract between dentists and society, no explicit social justice-oriented topics within undergraduate dental curricula, and no standardized tool to measure these topics. Further research is necessary to understand how such topics can be included in dental curricula to form socially competent dentists.

A systematic map of systematic reviews in pediatric dentistry--what do we really know?

OBJECTIVES

To identify, appraise and summarize existing knowledge and knowledge gaps in practice-relevant questions in pediatric dentistry.

METHODS

A systematic mapping of systematic reviews was undertaken for domains considered important in daily clinical practice. The literature search covered questions in the following domains: behavior management problems/dental anxiety; caries risk assessment and caries detection including radiographic technologies; prevention and non-operative treatment of caries in primary and young permanent teeth; operative treatment of caries in primary and young permanent teeth; prevention and treatment of periodontal disease; management of tooth developmental and mineralization disturbances; prevention and treatment of oral conditions in children with chronic diseases/developmental disturbances/obesity; diagnosis, prevention and treatment of dental erosion and tooth wear; treatment of traumatic injuries in primary and young permanent teeth and cost-effectiveness of these interventions. Abstracts and full text reviews were assessed independently by two reviewers and any differences were solved by consensus. AMSTAR was used to assess the risk of bias of each included systematic review. Reviews judged as having a low or moderate risk of bias were used to formulate existing knowledge and knowledge gaps.

RESULTS

Out of 81 systematic reviews meeting the inclusion criteria, 38 were judged to have a low or moderate risk of bias. Half of them concerned caries prevention. The quality of evidence was high for a caries-preventive effect of daily use of fluoride toothpaste and moderate for fissure sealing with resin-based materials. For the rest the quality of evidence for the effects of interventions was low or very low.

CONCLUSION

There is an urgent need for primary clinical research of good quality in most clinically-relevant domains in pediatric dentistry.
