Purpose: The purpose of this study was to compare the effectiveness of P_11-4 self-assembling peptide (CurodontTM Repair [CR]) and fluoride varnish with xylitol-coated calcium phosphate (Embrace TM Varnish [EV]) on enamel permeability and in the management of white spot lesions (WSLs) in primary teeth.

Methods: A clinical trial was conducted among 30 children aged three to five years with WSLs in 60 anterior teeth. They were randomly assigned to receive CR or EV. Preintervention and postintervention evaluation was done by International Caries Detection and Assessment System (ICDAS) and morphometric analysis. The secondary outcome was to assess the enamel permeability using scanning electron microscopy (SEM) of polyvinyl siloxane impressions.

Results: A statistically significant reduction in the ICDAS scores (P=0.05) and percentage area of WSLs in morphometric analysis (P=0.008) was seen in the CR group after six months. No statistically significant difference was observed in the EV group after six months. The SEM evaluation did not show a significant reduction in the percentage area of droplets in both the CR and EV groups (P=0.06 and P=0.21, respectively). No significant difference was seen between EV and CR in the three parameters assessed.

Conclusion: Curodont TM Repair is effective at remineralizing white spot lesions in primary teeth and can be considered as a remineralizing agent.

Purpose: The purpose of this study was to review the published studies that address the sense of coherence and its relationship with the oral health of children and adolescents.

Methods: This scoping review was structured according to the review method proposed by the Joanna Brigs Institute and conducted in accordance with PRISMA-ScR guidelines. The research was carried out in the following databases: Medline/ Pubmed^®, Lilacs^®, Scopus^©, Cochrane^©, Web of Science^©, and Embase^©.

Results: In this search, 358 studies were found, seven in Cochrane, 90 in PubMed^®, three in Lilacs^®, 101 in Web of Science^©, 80 in Scopus^©, and 77 in Embase^©, totaling 24 publications. The studies were published in nine countries, most of them cross-sectional studies.

Conclusions: Most studies have shown that a high sense of coherence (SOC) of both the caregiver and the child/adolescent is related to better oral health behaviors and a lower caries index. No conclusive information was observed on the relationship between SOC and periodontal diseases.

Purpose: The purpose of this study was to assess the outcome of coronal pulpotomy using mineral trioxide aggregate (MTA) in mature and immature teeth with symptoms indicative of irreversible pulpitis.

Methods: Fifty permanent molars with symptomatic irreversible pulpitis were divided into two groups according to complete or incomplete radicular growth (25 teeth in each group). Coronal pulpotomy was performed with MTA. Clinical follow-up evaluations were scheduled at the third, sixth, ninth, 12th, 18th, and 24th months. Follow-up radiographs were taken at the sixth, 12th, 18th, and 24th months. Pain levels were scored preoperatively and two days post-treatment.

Results: At two years of recall, 10 patients were lost to follow-up and the success of molars with complete or incomplete radicular growth were 100 percent and 95 percent, respectively. All teeth with periapical rarefaction were present preoperatively and showed complete radiographic healing. Radiographic evidence of dentin bridge formation was discernable in 31 of 38 cases.

Conclusions: Full coronal pulpotomy using mineral trioxide aggregate was successful in controlling pain and any infections after two years in 39 of 40 teeth regardless of whether they had immature or mature roots.

Purpose: The purpose of this study was to compare the wear resistance of stainless steel crowns, (SSCs), zirconia crowns (ZRCs), and nanohybrid crowns (NHCs) using a 3D tomography method.

Methods: Prefabricated SSCs, ZRCs, and NHCs (n equals 80) were worn for 400,000 cycles, equivalent to three years of simulated clinical wear, at 50 N and 1.2 Hz using the Leinfelder-Suzuki wear tester. Wear volume, maximum wear depth, and wear surface area were computed using a 3D superimposition method and 2D imaging software. Data were statistically analyzed using one-way analysis of variance with the least significant difference post hoc test (P<0.05).

Results: After a wear simulation of three years, NHCs had a 45 percent failure rate; NHCs also had the greatest wear volume loss (0.71 mm³), maximum wear depth (0.22 mm), and wear surface area (4.45 mm²). SSCs (0.23 mm³ , 0.12 mm, 2.63 mm²) and ZRCs (0.03 mm³ , 0.08 mm, 0.20 mm ²) had less wear volume, area, and depth (P<0.001). ZRCs were the most abrasive to their antagonists (P<0.001). The NHC (against SSC wearing group) had the greatest total wear facet surface area (4.43 mm²).

Conclusions: Stainless steel crowns and zirconia crowns were the most wear-resistant materials. Based on these laboratory findings, in the primary dentition, nanohybrid crowns are not recommended as long-term restorations beyond 12 months (P=0.001).

Purpose: The purpose of this cross-sectional observational investigation was to explore associations of site-specific tooth absences (SSTA, edentate sites resulting from dental agenesis where no primary or permanent teeth exist at the sites of permanent tooth agenesis) with the severity of oral health-related quality of life (OHRQoL) impacts in girls having nonsyndromic oligodontia.

Methods: Data collected from 22 girls (mean aged 12.0±2.9, standard deviation years) having nonsyndromic oligodontia (mean permanent tooth agenesis equals 11.6±3.6; mean SSTA equals 1.9±2.5) who completed a 17-item short format Child Perceptions Questionnaire (CPQ_11-14) questionnaire were analyzed.

Results: OHRQoL impacts were reported to be "often" or "every day/almost every day" by 63.6 percent of the sample. The mean total CPQ_11-14 score was 15.6±9.9. Higher OHRQoL impact scores were associated significantly with having one or more SSTA in the maxillary anterior region.

Conclusion: Clinicians should remain attentive to the wellbeing of the child with SSTA, and include the affected child in the treatment planning.

Purpose: To evaluate whether the postponement of dental elective procedures at the start of the COVID-19 pandemic was associated with an increased number of simple dental extractions, and/or decreased restorative procedures by analyzing data obtained from state-funded insurance dental claims.

Methods: Paid dental claims collected from March 2019 to December 2019 and from March 2020 to December 2020 for children ages two to 13 years old were analyzed. Dental procedures were selected based on Current Dental Terminology (CDT) codes for simple dental extractions and restorative procedures. Statistical analyses were performed to compare the rates of procedure types between 2019 and 2020.

Results: No differences in dental extractions but full-coverage restoration procedure rates per month and child were significantly lower than pre-pandemic (P=0.016).

Conclusion: Further study required to determine the impact of COVID-19 on pediatric restorative procedures and access to pediatric dental care in the surgical setting.

Purpose: The purpose of this study was to identify barriers to oral health services experienced by children and evaluate variation across demographic and socioeconomic population groups.

Methods: The data were collected from 1,745 parents/legal guardians who responded to a web-based survey regarding their children's access to health services in 2019. Descriptive statistics and binary and multinomial logistic models were used to examine barriers to needed dental care and factors contributing to differential experiences with those barriers.

Results: A quarter of children of responding parents experienced at least one barrier to oral health care, most commonly cost-related barriers. Child-guardian relationship type, having a pre-existing health condition, and dental insurance type increased the risk of encountering certain barriers two-to four-fold. Children with a diagnosed emotional, developmental, or behavioral condition (odds ratio [OR] equals 1.77, dental anxiety; OR equals 4.09, unavailability of needed services) and those with a Hispanic parent/guardian (OR equals 2.44, lack of insurance; OR equals 3.03, insurance not paying for needed services) were more likely to encounter various barriers than other children. The number of siblings, parent/guardian's age, education level, and oral health literacy were also associated with different barriers. The likelihood of encountering multiple barriers was over three times higher for children with a pre-existing health condition (OR equals 3.56; 95 percent confidence interval equals 2.30 to 5.50).

Conclusions: This study highlighted the significance of cost-related barriers to oral health care and suggested disparities in access among children with disparate personal and family backgrounds.
