Purpose: This study aimed to analyse parenting styles as a possible factor associated with caries in foster children and adolescents who had been victims of domestic violence.

Methods: The study was carried out in nine foster shelters in Recife, Northeast Brazil, with a sample of 88 participants aged 8 to 17 years old. Data were collected through intraoral examinations to verify deft/DMFT indices, applying the Demandingness and Responsiveness Scales to determine parenting styles. In turn, sociodemographic data were retrieved from records filed at the institutions. Descriptive analysis was performed, with the Mann-Whitney and Kruskal-Wallis tests being used to compare the categories of numerical variables.

Results: The mean deft/DMFT was of 3.78 in children (8 and 9 years old) and 1.93 in adolescents (10 years old and older). Overall, the index was of 2.31. Neglect was the main reason for the children's admission to foster care, while neglectful was the most prevalent parenting style.

Conclusion: Children of indulgent parents had higher caries indices in both deciduous and permanent teeth, while children of authoritative (permanent teeth) and authoritarian parents (deciduous teeth) had the lowest caries indices. However, no significant associations were found between caries and parenting styles.

Aim: To compare the shear bond strength and penetration ability of self-etch sealant with and without enamel deproteinization.

Materials and methods: A total of 37 sound extracted teeth were selected and 31 teeth were used for testing shear bond strength of self-etch sealant. For this, crowns portions of selected teeth were cut longitudinally with a diamond disc into a mesial and distal half, thereby yielding 62 samples. They were further divided into two groups; in Group 1, samples were deproteinised with 5.25% sodium hypochlorite and a sealant cylinder was built on the proximal surface. In Group 2, sealant cylinders were built without deproteinising the surface. Shear bond strength was tested using Universal Testing Machine. The remaining six teeth were used for penetration evaluation of self-etch sealant. In Group 1, the occlusal surface was deproteinised with 5.25% sodium hypochlorite and self-etch sealant was directly applied. In Group 2, sealant was applied without deproteinisation. The samples obtained after sectioning were observed under scanning electron microscope for sealant penetration. Mann-Whitney test and Chi-square analysis were utilised for statistical analysis.

Results: The results showed that the shear bond strength of the two groups was statistically not significant (p = 0.23). However, the comparison of % penetration revealed a statistically significant difference between the groups (p = 0.016).

Conclusion: Deproteinising the enamel surface prior to application of self-etch sealant enhanced the penetration ability of the sealant but did not show any effect on shear bond strength.

Purpose: Good oral health is important for children and adolescents with cystic fibrosis (CF). The purpose of this scoping review is to describe the existing evidence base regarding oral health in children and adolescents with CF and provide recommendations for future research.

Methods: Using a scoping review framework, a comprehensive search was undertaken using medline, embase, and PubMed. The search strategy included broad terms relating to CF, oral health, and children and adolescents and included only papers written in English.

Results: 61 articles were included. Topics investigated included dental caries, enamel defects, periodontal health, dental staining, oral health related quality of life, dental management, and dental development of children and adolescents with CF.

Conclusion: Dental outcomes of children and adolescents with CF differ from the healthy population. The current literature describing dental health in children and adolescents with CF includes predominately descriptive analyses. A shift to hypothesis-based studies to explore causal relationships that explain the differences in dental outcomes seen in the CF population offers an opportunity to better understand the problems faced by children and adolescents with CF. Research that actively engages stakeholders, including children and adolescents with CF and their families will enable evidence-based recommendations to improve their oral health.

Purpose: To describe the prevalence and the variables associated with TDIs in schoolchildren aged 8 to 14 years in Estância Velha city in southern Brazil, placing emphasis on molar incisor hypomineralization.

Methods: Students enrolled in public schools of a medium-sized city in the southern Brazil were selected using cluster random sampling. Clinical examinations assessed molar incisor hypomineralization-MIH (European Academy of Pediatric Dentistry criteria), dental caries (DMFT index), and TDIs (O'Brien's criteria). Socioeconomic and demographic variables were assessed using a standardized questionnaire. Prevalence ratios were estimated using Poisson regression (p < 0.05).

Results: 513 students (54.8% female), with a mean age of 11.6 (± 1.9) years, participated in the study. The prevalence of TDIs was 11.3%, with enamel fracture representing 90.4%. The high prevalence of traumatic dental injuries was associated with MIH (PR: 2.22 CI: 1.27; 3.87; p < 0.01) and overjet > 3 mm (PR: 2.03 CI 1.19; 3.45; p < 0.01).

Conclusion: The sample of schoolchildren from southern Brazil had a low prevalence of traumatic dental injuries. Molar incisor hypomineralization and increased overjet were associated with the higher prevalence of traumatic dental injuries.

Purpose: Nisin is a lantibiotic effective against Gram-positive microorganisms such as Streptococcus mutans. The study aimed to determine the effect of the addition of nisin to high-viscosity glass-ionomer cement (HVGIC) on its antibacterial activity, setting time, surface microhardness, and compressive strength.

Methods: 1 and 3% w/w nisin were added to HVGIC before mixing. Unmodified HVGIC was the control. Agar disc diffusion, direct contact test, and scanning electron microscopy (SEM) analysis were used to evaluate antibacterial activity against S. mutans. Setting time, surface microhardness, and compressive strength were measured using Gilmore needle apparatus, digital microhardness tester, and universal testing machine, respectively. Statistical analysis included Student's t test, one-way ANOVA with Tamhane's post hoc test, and repeated-measures ANOVA.

Results: As evidenced by the agar disc diffusion (p < 0.001), direct contact tests (p = 0.025), and SEM analysis of the S. mutans cell count and cell surface area (p = 0.049 and 0.003), 3% nisin had the strongest antibacterial activity. There was a dose-dependent increase in setting time (p = 0.005) and surface microhardness (p = 0.006), with no significant difference in compressive strength compared to control.

Conclusion: The addition of 3% nisin to HVGIC enhances the antibacterial action against S. mutans and surface microhardness without adversely affecting setting time and compressive strength.

Purpose: The study aims to evaluate the effectiveness of brainwave entrainment on pre-operative fear and anxiety in pediatric dental patients.

Methods: The study protocol received approval from the Institutional Ethical Committee under reference number 3010/IEC/2021. Pediatric patients (252) aged from 7 to 12 years, who reported to the dental department were randomized pre-operatively and presented either with brainwave entrainment (experimental), delivered using a "David delight plus device" or a standard behavior management protocol (control). Baseline and post-assessment of anxiety and fear levels were done using the Visual Facial Anxiety Scale and Frankl's behavior rating scale with Wright's modification. Vitals such as blood pressure and pulse rate were also measured.

Results: The study sample (n = 252) comprised 118 females and 134 males. The non-significant differences for values of (VFAS_1, FRS_1, HR_1, and BP₁₎ indicated similar baseline characteristics. In the brainwave entrainment group, the p values of the Mann-Whitney U test and Wilcoxon Signed Ranks test (p < 0.01) between the two-timepoints indicated a statistical difference for the values of (VFAS_1, FBRS_1, HR_1, BP₁₎ and (VFAS_2, FBRS_2, HR_2, BP₂₎.

Conclusions: Brainwave entrainment effectively reduces pre-operative fear and anxiety in pediatric dental patients. Therefore, they can be a non-pharmacological and non-invasive behavior management aid.
