Purpose: The purpose of this study was to quantify the impact of the COVID-19 pandemic on private dental insurance claims for pediatric dental care.

Methods: Commercial dental insurance claims for patients in the United States ages 18 and younger were obtained and analyzed. The claims dates ranged from January 1, 2019, to August 31, 2020. Total claims paid, average paid amount per visit, and the number of visits were compared between provider specialties and patient age groups from 2019 to 2020.

Results: Total paid claims and total number of visits per week were significantly lower in 2020 compared to 2019 from mid-March to mid-May (P<0.001). There were generally no differences from mid-May through August (P>0.15), except for significantly lower total paid claims and visits per week for "other" specialists in 2020 (P<0.005). The average paid amount per visit was significantly higher during the COVID shutdown period for 0-5 year-olds (P<0.001) but significantly lower for all other ages.

Conclusions: Dental care was greatly reduced during the COVID shutdown period and was slower to recover for "other" specialties. Younger patients ages zero to five years had more expensive dental visits during the shutdown period.

Purpose: The purpose of this study was to evaluate practice patterns among dentist anesthesiologists for pediatric patients with autism spectrum disorders (ASD) undergoing sedation for dental procedures.

Methods: An electronic nationwide survey was delivered to all members of the American Society of Dentist Anesthesiologists. The survey assessed provider training and comfort in treating pediatric patients with ASD, perioperative procedures for children with and without ASD, and preferred educational resources for the perioperative management of pediatric patients with ASD.

Results: Respondents were 114 dentist anesthesiologists and residents (33.3 percent response rate). Respondents indicated a high comfort level for managing pediatric patients with ASD for sedation (mean equals 91.9±14.74 [SD] percent). The average number of patients with ASD who respondents treat per week was 3.48±2.44). Providers reported making scheduling and staffing accommodations for patients with ASD. More than half of respondents reported no difference between patient groups in medication dosing for sedation and medication regimens used intraoperatively; however, only 43.9 percent of providers indicated using equivalent preoperative medication regimens for both patient groups, and providers reported increased usage of preoperative anxiolytic techniques with patients with ASD. Importantly, 87.7 percent of respondents reported the same incidence of adverse events during the perioperative period between groups.

Conclusions: Findings from this survey suggest there are both similarities and differences in how dentist anesthesiologists practice with pediatric patients with and without autism spectrum disorders. Additional research is warranted to measure the clinical benefits of modified practices for patients with ASD and identify best practices for this vulnerable population.

Purpose: The purpose of this retrospective study was to assess how procedural code trends reflect the adoption of evidence-based best-clinical-practice guidelines in a hospital-based pediatric dental residency program.

Methods: Data on frequency of indirect pulp therapy (IPT) and primary pulpotomy (P) utilization were assessed from 2008 to 2020.

Results: The rate of procedural change between IPT and P significantly differed (P<0.001) over 12 years. The total procedural frequency of IPT overcame P around the years 2014 to 2015.

Conclusions: From 2008 to 2020, indirect pulp therapy became the vital pulp therapy of choice in a hospital-based pediatric dental residency program. This trend likely reflects guidelines from major publications on the subject matter and changing philosophies on vital pulp therapy at this hospital-based residency program. Using available data (in this case, procedural codes), dental education programs can identify shifts in care and teaching trends on capstone procedures like vital pulpotomy.

Purpose: The purpose of this study was to evaluate the cytotoxicity of silver diamine fluoride (SDF) to human dental pulp stem cells (hDPSC). Methods: hDPSC were exposed to dilutions of 38 percent SDF ( 10-3, 10-4, and 10-5) and incubated for 24 hours. Cell viability was assessed with colorimetric detection assay at 24 hours. Fresh media was used as a negative control, and 0.1% sodium dodecyl sulfate was used as a positive control. Three independent experiments were performed in triplicate. Cell viability data were analyzed using analysis of variance and Tukey's multiple comparison test. Results: Cells exposed to dilution of 38 percent SDF 10-3 had an average cell viability of 17.0±3.5 (standard deviation) percent. Cells exposed to SDF 10-4 and 10-5 had an average cell viability of 101±2.5 percent and 94±4.4 percent, respectively. Dilution of 10-3 had significantly lower cell viability than the negative control (P<0.001). Dilution of 10-4 and 10-5 SDF had significantly higher cell viability than the positive control (P<0.001) and cells treated with a dilution of 10-3 (P<0.001). Conclusions: Thirty-eight percent silver diamine fluoride was cytotoxic to human dental pulp stem cells at a dilution of 10-3, but not at 10-4 and 10-5. In light of the cytotoxicity of SDF to hDPSC, this in vitro study supports the concern that exposure of the full concentration of 38 percent SDF to the pulp should be avoided.

Purpose: The purpose of this study was to assess the understanding of Spanish-speaking caregivers consenting to dental care using general anesthesia (GA) utilizing two consent-delivery pathways. Methods: Seventy-eight parents of children who never had GA were randomly assigned to one of two groups: (1) interpreter; or (2) video; they completed a survey to evaluate comfort level with GA and comprehension of areas of informed consent. Results: Most parents in both groups understood the risks associated with GA (89 percent in the interpreter group and 90 percent in the video group). The majority of families had difficulty understanding indications for GA (64 percent in the interpreter group versus 60 percent in the video group). Overall, 97 percent of participants believed they sufficiently understood the information presented about GA. The mean score for comfort level with GA was 7.03 for the interpreter group and 6.82 for the video group. Conclusion: Consent pathways used in this study were not significantly different for risk understanding and acquisition of consent-related knowledge.

Purpose: The purpose of this study was to evaluate the clinical and radiographic outcomes of direct pulp capping (DPC) using calcium hydroxide (CH), mineral trioxide aggregate (MTA), and premedicated DPC with formocresol (FC) in primary teeth. Methods: Sixty primary mandibular second molars with pulp exposures in children aged four to eight years old were treated using DPC. The molars were randomly divided into three groups (n equals 20 per group). Pulp exposures in the CH and MTA groups were capped directly using CH and MTA pastes, respectively, while those in the FC group were premedicated with FC and then capped with zinc oxide eugenol (ZOE) cement. All teeth were finally restored with stainless steel crowns, and clinical and radiographic evaluations were carried out at baseline and three, six, and 12 months after restoration. Fisher's exact test was performed to define the significance between the groups and follow-up periods. Results: The clinical and radiographic findings showed no significant difference between the three groups. The overall success in the CH, MTA, and FC groups were 88.2 percent, 100 percent, and 73.3 percent, respectively. However, these differences were not statistically significant (P>0.05). Conclusion: All three materials examined in this study exhibited clinical and radiographical efficacy when used as direct pulp capping materials.

Purpose: The purpose of this study was to evaluate the clinical performance of composite strip crowns (SCs) and zirconia crowns (ZCs) on primary maxillary incisors affected by early childhood caries over 18 months. Methods: A total of 111 primary maxillary anterior teeth were included in 25 three-to five-year-old children. In each patient, the teeth were randomized to the SC and ZC groups (n equals 43 teeth/group) and sound teeth as the control group (n equals 25) in a split-mouth design. Patients' oral hygiene and clinical variables, including gingival health, plaque accumulation, pulpal health, secondary caries, retention, color match, and material loss, were assessed at baseline and at one, six, 12, and 18 months. Data were statistically analyzed using Fisher's exact test, the Friedman test, and the Kruskal-Wallis test. Results: Zirconia crowns had significantly lower plaque index values than strip crowns and controls during all recalls (P<0.05). The gingival index scores of both crowns improved after six months, while mild inflammation persisted in both groups due to increased exfoliation mobility. ZCs had better color match and retention (P<0.05) than SCs, with the latter being 100 percent for ZCs and 77.8 percent for SCs. Both crowns had similar and high pulp survival at 18 months (ZC equals 93.1 percent; SC equals 95.4 percent). Conclusions: Zirconia crowns had better clinical performance than composite strip crowns in terms of retention, restoration failure, and color change but similar gingival and pulpal health after 18 months. ZCs showed the lowest plaque accumulation when compared with sound teeth and SCs.

Purpose: To assess the prevalence and severity of developmental defects of enamel (DDE) in primary teeth and maternal-associated factors. Methods: This cross-sectional study included 336 two- to four-year-old children who attended the National Day of Children's Vaccination in São Paulo State, Brazil. The modified DDE index was used for diagnosis. Mothers completed sociodemographic and health questionnaires. Descriptive and Poisson regression analyses were performed. Results: The prevalence of DDE was 50.6 percent. The most frequent defects were demarcated opacities (45.0 percent), diffuse (36.0 percent) opacities, and hypoplasia (5.8 percent). White opacities were predominant (64.8 percent) in the teeth with defects, followed by cream (20.4 percent), yellow (5.2 percent), and brown (1.9 percent). Most defects involved less than one-third of the tooth surface (80.2 percent). The prevalence of DDE was associated with maternal-child factors such as alcohol consumption during pregnancy (prevalence ratio [PR] equals 1.27; 95 percent confidence interval [95% CI] equals 1.03 to 1.55), child hospitalization for infectious disease in the first year of life (PR equals 1.32; 95% CI equals 1.05 to 1.67), and breastfeeding for the first 12 months of life (PR equals 0.53; 95% CI equals 0.45 to 0.62). Conclusions: Developmental defects of enamel showed high prevalence and mild severity in the primary dentition. Alcohol consumption during pregnancy and child hospitalization for infectious diseases in the first year of life were associated with an increased prevalence of DDE. Moreover, children who breastfed for 12 months had a lower prevalence of DDE in primary teeth.

Purpose: To evaluate early preventive dental services (PDS) provided by primary care providers (PCPs) in reducing future caries treatments among Alabama Medicaid recipients. Methods: Data from 2009 to 2019 Alabama Medicaid were used to evaluate effectiveness of 1st Look Program on PDS before age three years and incidence of caries treatments after age three years. PDS groups consisted of 1st Look-involved (PDS claims from PCPs), dentist-only (PDS claims from dental providers), and no early fluoride treatment participants (no PDS claims before age three years). Outcomes included frequency and expenditures of fluoride applications, simple restorations, and extensive treatments. Regression models were used to evaluate associations between PDS groups and outcomes while controlling for covariates. Results: Children in 1st Look- involved received more fluoride (3.0 versus 2.1 times; P<0.001) and were applied earlier (12.1 versus 22.9 months old; P<0.001) than dentist-only group. After adjusting for covariates, compared to dentist-only, 1st Look-involved group received earlier fluoride (beta value equals -11.1 months; 95 percent confidence interval [95% CI] equals -11.25 to -10.97) with greater frequency (incident rate ratio equals 1.49; 95% CI equals 1.47 to 1.51). Caries treatment counts were highest in dentist-only followed by 1st Look-involved and no early fluoride treatment groups in both simple restorations (2.7 versus 2.0 versus 0.2 times; P<0.001) and extensive treatments (2.8 versus 2.3 versus 0.2 times; P<0.001), which were consistent after adjusting for covariates. Conclusions: PDS were provided earlier by PCPs in Medicaid-qualified children, with reduced caries treatments on primary teeth, compared to PDS by dental providers only.
