RESUMEN
BACKGROUND: Health literacy (HL) refers to an individual's ability to access, understand, and apply health information to make informed decisions about their health. On the contrary, oral health literacy (OHL) focuses on an individual's ability to understand and utilize oral health information to maintain good oral health. AIM: This study presents a comprehensive literature review that explores the theoretical foundations and practical applications of HL and OHL. DESIGN: A comprehensive search was conducted using keywords on the following databases: PubMed, Google Scholar, and Cochrane Database of Systematic Reviews. RESULTS: The existing literature on various aspects of HL, including the most common used definitions of HL, conceptual frameworks, and consequences of limited health and OHL, was summarized. Additionally, the review discussed the significance of HL and OHL. Also, the relation between parent level of OHL and children's oral health was described. It further highlights modern approaches that have been shown in previous studies to improve the OHL of primary caregivers. CONCLUSIONS: Understanding the significance of HL and OHL is crucial in developing effective interventions that can address disparities and improve oral health outcomes for individuals of all backgrounds.
RESUMEN
OBJECTIVES: Zein-coated magnesium oxide nanoparticles (zMgO NPs) can potentially improve cement adaptation to the tooth-restoration interface, which would aid in minimizing marginal leakage and secondary caries. The aim of this study was to assess the effect of incorporating zMgO NPs on the adaptation of self-adhesive resin cement using cross-polarization optical coherence tomography (CP-OCT) and scanning electron microscopy (SEM). METHODS: Resin inlays were fabricated to be cemented in Class-I cavities of extracted human molars. All specimens were randomly divided into five groups (n = 10), and the resin inlays were cemented using self-adhesive resin cement with various concentrations of zMgO NPs (0% [control], 0.3%, 0.5%, 1%, 2%). Characterization was done by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and SEM. The specimens were examined for interfacial adaptation under CP-OCT. Floor and wall adaptation measurements were analyzed by software on 20 B-scans, and samples were sectioned for interfacial measurement by SEM. RESULTS: Results for CP-OCT and SEM showed a statistically significant increase of adaptation in the floor and wall of resin cement filled with zMgO NPs compared to the control. The samples enhanced with 0.3% and 0.5% showed a statistically significantly better adaptation in floor and wall in CP-OCT and SEM. However, there was no significant difference between the 1%, 2%, and control groups for CP-OCT and SEM analysis. SIGNIFICANCE: The incorporation of zMgO NPs in self-adhesive resin cement can enhance the cement's properties by significantly improving its wall and floor adaptation.

INTRODUCTION: Zein-incorporated magnesium oxide nanoparticles (zMgO NPs) can influence the mechanical properties of dental materials. However, the effect of this addition on the mechanical properties of resin composite has yet to be investigated. The objective of this study was to add various concentrations of zMgO NPs to conventional, flowable, and bulk-fill composite and assess the effect on the compressive strength, flexural strength, and microhardness. METHODOLOGY: 150 samples each of conventional composite, flowable composite, and bulk-fill composite (n = 450) were enhanced with concentrations of zMgO NPs at 0 %, 0.3 %, 0.5 %, 1 %, and 2 % (n = 30). 10 samples of each group were randomly allotted to the compressive strength, flexural strength, or hardness test. Characterization of the specimens was performed by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and transmission electron microscopy. Two-way ANOVA test was used to compare between groups, and one-way ANOVA followed by Tukey's test was done at p = 0.05 to determine significance. RESULTS: Characterization yielded a uniform distribution of nanoparticles in the matrix and the formation of a new hybrid composite that maintained its properties. Composite of all types enhanced with 0.3 % and 0.5 % zMgO NPs demonstrated a statistically significant increase in compressive strength, flexural strength, and hardness when compared to the control (p < 0.05). The bulk-fill composite with zMgO NPs concentrations of all groups demonstrated a statistically significant increase (p < 0.05) in hardness when compared to the control. CONCLUSION: The modified composites' compressive strength, flexural strength, and hardness improved or remained consistent. CLINICAL SIGNIFICANCE: An improved dental resin composite will enhance the quality of care and patient experience. The augmented strength and hardness of resin composite is desirable in prolonging the durability of the restoration.
RESUMEN
The aim of this review was to evaluate the association between parental oral health literacy and children's oral health outcomes. A comprehensive search was conducted across four electronic databases to identify articles that were published up to October 2023. The articles that met our predetermined criteria were then screened and assessed for eligibility. Updated Arksey and O'Malley's scoping review framework was followed. After identifying 2964 references, duplicates were removed, leaving 1992 titles. Following the screening of article titles and abstracts, 19 full-text articles underwent a thorough examination. The scoping review included 19 relevant studies. In most of the studies included, the status of oral health of children is linked to the caregiver's oral health literacy. Children of caregivers with low oral health literacy were found to exhibit deleterious oral health habits, including inadequate teeth brushing and the use of bottles at night-time. Dental caries was found to be more common in children whose parents had low oral health literacy. Striving for optimal oral health literacy in the community is a valuable and worthwhile effort. Equipping parents with the skills and knowledge to make appropriate decisions about their children's oral health could positively prevent dental caries and promote better oral health outcomes.

INTRODUCTION: Zein-incorporated magnesium oxide nanoparticles (zMgO NPs) were found to be effective against the bacteria S. mutans, S. aureus, E. faecalis and C. albicans, and can impart this antimicrobial effect on the resin composite it is integrated with. However, the effect of different light curing systems on the mechanical properties of this novel biomaterial has yet to be investigated. The objective of this study was to assess the effect of light-emitting diode (LED) and quarts-tungsten halogen (QTH) light curing systems on the compressive strength, flexural strength, and microhardness of bulk-fill resin composite modified with zMgO NPs. METHODOLOGY: A Teflon mold was used to fabricate 180 bulk-fill composite samples with concentrations of zMgO NPs at 0%, 0.3% and 0.5% (n = 60). Samples of each group were allocated to light curing by LED or QTH, after which 10 samples of each group were allotted to a mechanical test. Characterization of the specimens was performed by X-ray diffraction, field emission scanning electron microscopy and Fourier transform infrared spectroscopy. Two-way ANOVA and Tukey's post-hoc test was conducted at P = .05 to determine significance. RESULTS: The characterization revealed a uniform distribution of nanoparticles in the matrix and the formation of a new hybrid composite that maintained its properties. The compressive strength of the 0.3% zMgO composite for the QTH group significantly increased, while the remaining groups underwent no significant change. There was no significant difference among the groups for the flexural strength and microhardness tests. CONCLUSION: The modified composites' compressive strength, flexural strength, and microhardness improved or remained consistent. Long-term clinical studies can further substantiate the enhanced resin composite. CLINICAL RELEVANCE: The modified composite will exhibit similar or improved mechanical properties whether an LED or QTH light cure device is used. The addition of an antimicrobial effect to bulk-fill resin composite will aid in the prevention of secondary caries.
