Purpose: The purpose of this study was to longitudinally evaluate follow-up treatment on primary teeth initially treated with silver diammine fluoride (SDF). Methods: This retrospective cohort evaluated private insurance (not Medicaid) claims data from 2018 to 2019 for children no older than 12 years with at least one primary tooth initially treated with SDF. Additional treatment per tooth was recorded over a follow-up of at least 24 months. Results: The mean and standard deviation (±SD) age of 46,884 patients was 5.7±2.3 and for SDF-treated teeth per patient was 2.6±2.1. Forty percent (95 percent confidence interval [95% CI] equals 39 to 40.7 percent) of teeth initially treated with SDF received additional treatment. The odds of SDF-treated teeth receiving future treatment significantly decreased with patient age by 22 percent per year (odds ratio equals 0.78; 95% CI equals 0.077 to 0.79; P<0.001). Pediatric dentists had only slightly lower odds than general dentists for providing additional treatment (0.91, P<0.001). Posterior teeth and teeth expected to exfoliate in two or more years had significantly higher odds of receiving additional treatment (2.47 and 1.27, respectively, P<0.001). Conclusions: Beginning at age four, patient age at placement of silver diammine fluoride was inversely proportional to future treatment provided. Posterior teeth and teeth expected to exfoliate in two or more years were more likely to receive additional treatment.

Purpose: The purpose of this study was to perform a systematic review to assess current evidence for the association between child temperament and early childhood caries (ECC). Methods: A systematic search was conducted using MEDLINE® through PubMed®, EMBASE®, Scopus®, LILACS, Web of Science™, and EBSCO up to January 2023. Studies measuring ECC and child temperament for children younger than or equal to six years of age using questionnaires, interviews, and surveys through case-control studies, cohort studies, and cross-sectional studies were included. Literature reviews were excluded. Medical subject heading (MeSH) terms like "temperament" and "dental caries" were used by two authors who independently extracted the data, and a third author resolved disagreements. Risk of bias assessment was done using the Newcastle-Ottawa assessment scale for case-control and cohort studies and the Appraisal tool for Cross-Sectional Studies (AXIS). The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations approach (GRADE approach). A chi-square test and I-square index were used to evaluate heterogeneity. Results: A total of 5,072 records were screened, resulting in 15 included studies that yielded data for 6,667 participants; sevenstudies were high, and eight were of moderate quality. Seven studies qualified for meta-analysis, which revealed that persistence did not affectthe presence or absence of ECC. However, there was a strong association between difficult temperament and ECC (odds ratio equals 2.63). Conclusion: A positive association between a child's temperament and early childhood caries exists that is supported by quantitative findings, indicating a connection with very low certainty.

Purpose: The purposes of this in vitro study were to evaluate the effect of three isolation methods to mitigate bioaerosols during stainless steel crown (SSC) preparations and assess the distribution of Streptococcus mutans by aerosolization in closed-room operatories. Methods: Melamine teeth coated in laboratory-grown S. mutans biofilm were prepared for SSCs using three different isolation methods. Agar plates were placed in five locations throughout the operatory and opened during each preparation as well as for 10 minutes immediately following to collect aerosolized S. mutans. Bacterial colonies were counted after incubating plates for 48 hours. Data were analyzed for differences between the isolation method and plate locations. Results: Bacterial colony counts for teeth prepared using high-volume evacuation suction (HVE) with dental dam (DD) isolation were statistically significantly higher than for those prepared using HVE with a DryShield®(DS) and HVE with no isolation at the assistant (A) (P<0.001), operator face shield (FS) (P<0.001), and patient (Pt) (P=0.002) locations. No significant differences were found among isolation methods for parent (Pa) or rear delivery (RD) locations. The location that produced the most bacterial colony counts using HVE with DD isolation was FS (P<0.001), followed by A (P=0.04), Pt (P<0.001), and RD and Pa (P<0.001). Counts produced from teeth prepared with DS isolation were significantly higher at the Pt location than the A (P<0.001), FS (P=0.002), RD (P<0.001), and Pa (P=0.008) locations. Conclusion: The use of dental dam with high-volume evacuation suction during stainless steel crown preparations increased bioaerosols near the procedure, while dental evacuation systems (DryShield®) may effectively limit their spread.

Purpose: The purposes of this study were to evaluate the effect of silver diammine fluoride (SDF) on the shear bond strength (SBS) of pink opaquer (PO) compared to resin-modified glass ionomer (RMGI) and conventional composite (COMP) on demineralized dentin, and also to investigate the mode of failure (MOF). Methods: Sixty extracted third molars were prepared, demineralized for 14 days, and divided into four groups: (1) COMP; (2) SDF+PO; (3) SDF+RMGI; and (4) SDF+COMP (restoration size: two by two mm). SBS, MOF, modified adhesive remnant index (MARI), and remnant adhesive volume (RAV) were evaluated using an Instron® machine, light microscopy, 3D digital scanner ( 3Shape©), and GeoMagic Wrap© software. Results: There was no significant difference in SBS (MPa) among the COMP mean??standard deviation (2.5±1.59), SDF+COMP (2.28±1.05), SDF+PO (3.31±2.63), and SDF+RMGI groups (3.74±2.34). There was no significant difference in MOF and MARI among the four groups (P>0.05). There was no significant difference in RAV (mm3) among the COMP (0.5±0.33), SDF+COMP (0.39±0.44), SDF+PO (0.42±0.38), and SDF+RMGI groups (0.42±0.38; P>0.05). A significant correlation existed between MOF and RAV (R equals 0.721; P<0.001). MOF, MARI, and RAV did not show any correlations with SBS (P>0.05). Conclusions: Silver diammine fluoride does not affect shear bond strength between carious dentinal surface and tooth color restorative materials. The amount of material left on the interface is not related to the amount of shear force needed to break the restoration.

Purpose: The purpose of this study was to investigate the microleakage of atraumatic glass ionomer restorations with and without silver diammine fluoride (SDF) application. Restorations with SDF are termed silver-modified atraumatic restorations (SMART). Methods: Sixty carious extracted permanent teeth were randomly allocated to two SMART groups and two control groups (n equals 15 per group) for a total of four groups. After selective caries removal, test specimens were treated with 38 percent SDF and polyacrylic acid conditioner was applied and rinsed; teeth were restored with Fuji IX GP® glass ionomer (n equals 15) or with SMART Advantage™ glass ionomer (SAGI; n equals 15). For control groups, specimens were restored with their respective GI material after selective caries removal, both without SDF. Restored teeth were placed in Dulbecco's Phosphate-Buffered Saline solution at 37 degrees Celsius for 24 hours. Teeth were thermocycled between five and 55 degrees Celsius for 1,000 cycles, stained with two percent basic fuchsin, sectioned, and visually inspected for microleakage utilizing stereomicroscopy on a four-point scale. Data were statistically analyzed using Kruskal-Wallis one-way analysis of variance on ranks using Dunn's method (P<0.05). Results: Microleakage between the two SMART restoration groups was insignificant. SAGI alone demonstrated significantly more microleakage than all other groups. There was no statistical significance between the Fuji IX GP® control group and the two SMART restoration groups. Conclusions: This in vitro study indicated that silver diammine fluoride placed before glass ionomer restoration does not increase microleakage. Polyacrylic acid may be used after SDF placement without increasing microleakage.

Purpose: To describe social determinants of health (SDOH) in a group of children with special health care needs (CSHCN) planned for dental procedures with general anesthesia (GA) at a pediatric hospital and explore associations between SDOH and completing this treatment in the recommended timeframe. Methods: SDOH were recorded for all patients planned for dental treatment with GA in 2019. Outcomes were treatment completed in the recommended timeframe or treatment not completed within two years of planning. Results: Dental surgery plans were made for 390 CSHCN: 190 were completed in the recommended timeframe, and 119 were not completed within two years. The SDOH associated with completing/not completing surgery were parents (guardian/caregiver)/household, and documentation of social work involvement with the family. Patients receiving optimally timed surgery more frequently had two parents/one household and/or an active social work plan on the record. Those not receiving surgery frequently had two parents/two households, single parents, and/or had no social work plan. Ethnicity, payer, and the need for an interpreter were not associated with receiving timely surgery. Conclusions: Multiple studies have found that social determinants of health contribute to disparate health outcomes. In this study, children with two parents in one household appear to be advantaged in receiving care in the recommended timeframe. Families with SDOH challenges who had a social work plan were frequently able to overcome SDOH barriers and receive dental treatment with general anesthesia in the timeframe recommended.

Purpose: The purpose of the study was to determine whether visiting only a pediatric dentist (as opposed to visiting only a general dentist) was associated with the provision of preventive dental services for a U.S.-based pediatric population (those 18 years and younger). Methods: This study analyzed pooled Medical Expenditure Panel Survey data from 2018 and 2019 to compare the use of certain preventive dental services (i.e., examination, radiographs, prophylaxis, dental sealant, and fluoride treatment) among those who reported visiting a pediatric dentist versus those who visited a general dentist. Survey procedures were used in Stata 14.0 to perform multivariable logistic regression analyses. Results: Controlling for demographic and insurance variables, children who visited only pediatric dentists had statistically significantly greater odds of receiving radiographs (adjusted odds ratio [AOR] equals 1.22; 95 percent confidence interval [95% CI] equals 1.01 to 1.48; P=0.04), fluoride treatment (AOR equals 1.57; 95% CI equals 1.30 to 1.90; P≤0.001), and sealants (AOR equals 1.63; 95% CI equals 1.24 to 2.16; P=0.001) compared to children who visited only general dentists. There was no statistically significant difference in the provision of periodic examinations and prophylaxis services. Conclusion: Based on the nationally representative data evaluated, pediatric dentists are more likely to provide more optimal preventive services than general dentists (i.e., radiographs, fluoride treatments, and sealants) to children in the United States.

Purpose: The purpose of this cross-sectional study was to evaluate the association between clinician-assessed (actual) and self-assessed (perceived) dentofacial features and their association with bullying in schoolchildren. Methods: The sample comprised 519 schoolchildren aged 10 to 12 years old (235 boys and 284 girls) randomly selected from private and public schools. Clinical evaluations were performed to record dento- facial features, and the children were asked a self-reported questionnaire about their personal experience of bullying and perceived dentofacial features. Descriptive statistics (counts and percentages) as well as chi-square to analyze the association between variables were applied. Results: The results showed that 57.2 percent of the children reported being bullied, and the mainly perceived dentofacial features cited were: "crooked teeth" (46.3 percent), "shape or color of teeth" (45.5 percent), "upper front teeth sticking out" (43.8 percent), and "having a gap between the teeth or having missing teeth" (35.5 percent). Statistically significant associations between actual and perceived dentofacial features and involve- ment in bullying were observed for anterior crowding (P=0.01), anterior crossbite (P<0.001), lip competence (P=0.008), and anterior dental trauma (P=0.04). Conclusion: Some actual and perceived dentofacial traits are associated with bullying, so these features and the schoolchil- dren's compliances should be considered to determine the treatment need.
