Bioactive materials have emerged as a promising alternative to conventional restorative materials as part of more conservative dentistry. The aim of this study was to evaluate and compare the shear bond strength (SBS) and microleakage of a new bioactive restorative material, two bulk-fill restorative composites, and a conventional composite at 24 h, 4 weeks, and 8 weeks. Three hundred and sixty molars and premolars were divided into four groups: ACTIVA™ BioACTIVE Restorative™, Filtek™ Bulk-Fill Restorative Composite, Tetric^® N-Ceram Bulk-Fill Composite, and G-aenial^® Composite. The normality of the data was determined with the Kolmogorov-Smirnov test, then the two-way ANOVA and Fisher’s test were used for analyzing SBS data, and the Kruskal-Wallis and DSCF tests were conducted to analyze the microleakage. In the SBS test, there were no statistically significant differences between materials (p = 0.587), and the relation between material and time (p = 0.467), time points showed statistically significant differences (p = 0.016). As for the microleakage, statistically significant differences were found for all three time periods (p < 0.05), showing the conventional composite to have the lowest microleakage, followed by the bioactive material, and lastly the two bulk-fill composites. In conclusion, the new bioactive material has similar evaluated properties to bulk-fill composites (bond strength) and conventional composites (bond strength and microleakage) and can be used as an alternative restorative material.

The present study aimed to evaluate and compare the level of oral health among Spanish and immigrant children residing in Barcelona, Spain. Oral health status was evaluated in 1400 children aged 3 to 14 years between September 2018 and June 2019. Multiple variables (dental caries lesions, exodontia, trauma, malocclusions, gingivitis, fillings, stainless steel crowns in primary dentition, and pit and fissure sealings in permanent dentition) were compared in both populations. Statistically significant differences (p < 0.001) were found in the prevalence of caries in the primary dentition, which was higher in the immigrant group (62.3%) than in the Spanish group (42.6%). For the permanent dentition, the prevalence of dental caries lesions was 12.2% in Spanish children and 16.4% in immigrant children, showing statistically significant differences (p = 0.026) between the two groups. The prevalence of fillings in the primary dentition was 14.6% in Spanish and 12.5% in immigrant children (p = 0.253). Regarding the permanent dentition, the number of fillings was also higher in the Spanish population (6.8%) compared to the immigrant population (3.5%), again evidencing statistically significant differences (p = 0.006). Our findings suggest a better oral health status in Spanish children than in immigrant children.

The longevity and acceptance of aesthetic dental materials are directly proportional to color stability. The aim of this study was to analyze the relationship between the use of multivitamins and the color stability of dental restorative materials. A total of 45 discs of nanohybrid composite, 45 of Reinforced Glass Ionomer (RGI), and 45 of Giomer were prepared. Subsequently, the samples were randomly divided into three solution groups (n = 15): Group 1—Sambucol Pediatric Syrup, Group 2—Hidropolivital Baby Drops, and Group 3—artificial saliva, which is preparation for patients with xerostomia. For 28 days, the specimens were immersed in 10 mL of each multivitamin for two minutes every 24 h. Color measurements were repeated on days 7, 14, 21, and 28. Statistical analysis was performed using the Jamovi software version 2.2.5, employing the Shapiro–Wilk test for normality and the Kruskal–Wallis test for non-parametric data. When comparing materials, statistically significant differences (p < 0.001) were observed between RGI and Giomer, and RGI and composite, but not between Giomer and composite (p = 0.716). The highest change was observed in RGI–Hidropolivital ΔE₀₀ = 3.27 (2.38–4.59) and the least in composite–Sambucol ΔE₀₀ = 0.72 (0.30–1.18). In conclusion, the exposure time and the multivitamin influence the color change of restorative materials.

Background: Oral surgery involves the diagnosis and surgical treatment of diseases affecting the soft and hard tissues of the oral cavity and encompasses a wide range of surgical interventions. The aim of this investigation was to study the characteristics and age-related diagnoses of these oral surgeries, as well as to describe the surgical procedures performed in a pediatric oral and maxillofacial surgery service. Methods: A descriptive, retrospective, observational, and relational study was conducted on children and adolescents aged from 0 to 22 years who were treated in a pediatric oral and maxillofacial surgery service at a children’s hospital. Results: We analyzed 1311 surgical interventions (51.4% were on boys and 48.6% on girls), consisting of 24.8% soft tissue surgeries, 65.9% bone and dental tissue surgeries, and 9.3% mixed tissue surgeries. The most common pathologies were tooth eruption disorders (65.9%), followed by ankyloglossia (20.5%). The most frequent treatment was wisdom teeth extraction (31.3%). A statistically significant association (p < 0.05) was found between surgical treatments and variables such as age, sex, tissue type, and biopsy. Conclusions: This study enhances our understanding of pediatric oral surgery, emphasizing that the most common pathology is altered tooth eruption, while the most frequent surgical intervention is the extraction of wisdom teeth at different stages of development.

Assessing parental aesthetic acceptability of Silver Diamine Fluoride (SDF) staining is crucial for its potential implementation in paediatric dentistry in different regions. This study aimed to compare aesthetic perceptions and acceptance of SDF staining between Spanish and Italian parents, and assess weather acceptability is influenced by location, child’s cooperation, or demographic background. A cross-sectional comparative study was conducted among Spanish and Italian parents at three university dental clinics, using a validated Italian version of the questionnaire “Parental perceptions of Silver Diamine Fluoride Dental Color Changes”. 264 Spanish and 234 Italian parents participated in the survey. 41.8% of Spanish parents, compared to 65.4% of Italians, considered staining on posterior teeth acceptable (p < 0.001). 17.2% of Spaniards rated anterior teeth acceptable, versus 19.3% of Italians (p < 0.001). Italian parents showed increased acceptability as child’s cooperation decreased. Acceptability levels in Spain remained more homogeneous, despite linear mixed model identifying a significant increase in acceptability scores from ‘collaboration’ to ‘non-collaboration’ scenario. Spanish and Italian parents found SDF staining on posterior teeth more acceptable than on anterior regions. Level of acceptance increased with child’s uncooperative behavior. Spanish parents generally demonstrated a lower acceptance of SDF pigmentation compared to Italians. Trial registration: NCT, NCT06384326.

Molar Incisive Hypomineralization (MIH) is a condition in the dental enamel of multifactorial etiology and, in part unknown. This study aimed to determine if there are coincident family or sociodemographic patterns in the group of pediatric patients diagnosed with MIH. A cross-sectional descriptive observational study. An oral examination was performed to diagnose the presence or absence of MIH in children aged 6 to 14 years who attended the Dentistry Service of the Primary Care Center in Roquetes, Catalunya, Spain, plus a questionnaire created ad hoc with sociodemographic and family structure variables that the parents filled out during the visit. A total sample of 305 patients was recruited; 153 had MIH and 152 did not. The sample was grouped, according to the country of maternal origin: (1) children with a mother of Spanish nationality (44.92%), and (2) children with a mother of foreign nationality (55.08%). In group 1, a significant association was found between having MIH and the variables “Mother with higher education” (p-value = 0.002); “Child does not live with both parents” (p-value = 0.012); “Place of birth of the child other than the place of current residence” (p-value = 0.002). In group 2, the variables correlated with MIH were: “Mother’s locality different from the father’s locality” (p-value = 0.002); “Mother’s locality different from the child’s birth” (p-value = 0.001). Unfavorable sociodemographic factors, the phenomenon of migration, and the family structure of not living with both parents were associated with the presence of MIH in the children in the present study.
