ABSTRACT Objective: To investigate associations/correlations between bone alterations and vitamin D status in children through data mining analyses based on observational studies. Material and Methods: Searches in PubMed, Scopus, Web of Science, and Embase databases were performed to recover studies, published until October 2022, with healthy children, which investigated the vitamin D status, related or not to undesirable bone alterations linked to bone quality (bone mineral density and bone mineral content), fracture or anthropometry. Country, study design, area of expertise (medicine, nutrition, dentistry, others), bone outcome, 25-hydroxyvitamin D data (serum or intake levels), the exams for bone diagnosis, and the results were analyzed in the VantagePointTM software. Results: Of 20,583 studies, 27 were included. The USA (n=9; 33.3%) had the highest number of publications. Cross-sectional (n=11; 40.7%), case-control (n=9; 33.3%), and cohort studies (n=7; 25.9%) contemplated the medicine and nutritional areas without any study in dentistry. Studies about bone quality (n=21; 77.8%), analyzed through dual-energy X-ray absorptiometry (DXA; n=14; 51.8%), with association (n=16; 59.2%) between the low serum levels of 25-hydroxyvitamin D and undesirable bone alterations (n=14; 51.8%) were the most prevalent. Conclusion: Most studies were conducted in the medical area and showed an association between low bone quality and low levels of 25-hydroxyvitamin D, verified through DXA.

Abstract Objective: To summarize data of clinical trials that used silver diamine fluoride (SDF) to prevent and treat caries lesions and dentinal hypersensitivity. Material and Methods: Six electronic databases were searched in May 2022. The concentration of SDF, type of usage (alone/combined), dentition, anterior/posterior teeth, tooth region, dental tissue, number of the treated surfaces, the intervention environment, participants' age, frequency and duration of SDF application, purpose, and outcome were the extracted variables. The type of study, year of publication, authors, journals, and country were also investigated. Results: From 8860 articles, S3 were selected. Most were randomized (n=38), that applied 38% SDF (n=43), alone (n=44), on multiple surfaces (n=44), only in dentin (n=36), of the crown (n=46) of anterior and posterior (n=36) primary teeth (n=39). The studies were preferably carried out outside the clinic (n=3l), only in children (n=33), with reapplication of SDF (n=30), but did not inform the duration of application (n= 19). SDF was most used to treat (n=46) only caries lesions (n=50). They were published between 2001 and 2022, mainly in the Journal of Dentistry (n=10). China (n=19) and Lo E.GM (n=19) were the countries and authors that published the most, respectively. Conclusion: The silver diamine fluoride 38% alone was most used to treat caries lesions in the dentin of the crown of all primary teeth, preferably applied on multiple surfaces, requiring re application, and outside the clinic.

Abstract To assess the in vitro and in situ effect of experimental combined fluoride and calcium nanocomposite solutions on dental caries prevention. Nanocompound mesoporous silica (MS) with calcium (Ca) and sodium fluoride (NaF) - (MSCaNaF); MS with NaF (MSNaF), NaF solution (positive control), and deionized water (negative control - CG) were studied. The specimens (n=130) were submitted in vitro to a multispecies biofilm in the presence of 2% sucrose. After 24 h and 48 h, the culture medium pH, the percent of surface mineral loss (%SML), and lesion depth (ΔZ) were analyzed. In the in situ study, 10 volunteers participated in four phases of 7-days each. The products were applied on the specimens (n=240) before 20% sucrose solution drips. The polysaccharides (SEPS and IEPS), %SML and roughness (Sa) were evaluated. There was an in vitro decrease in pH values in 24h and 48h, compared to baseline. The MSCaNaF and MSNaF groups obtained lower values of %SML and ΔZ (p < 0.05) than CG and NaF after 24h and were similar to NaF after 48h (p<0.05). In situ results showed similar SEPS and IEPS among all groups after 48h. An after 7-days, the nanocomposites had similar values (p>0.05), while NaF was similar to CG (p>0.05). After 48h, the MSCaNaF and MSNaF reduced the %SML (p<0.05). After 7-days, both experimental nanocomposites were similar to NaF (p>0.05). Regarding Sa, MSCaNaF was better than NaF for both periods (p<0.05). The nanocomposites controlled the in vitro and in situ enamel demineralization, mainly in the initial periods. prevention (MS Ca (Ca (NaF (MSCaNaF) MSNaF, , (MSNaF) positive control, control) negative studied n=130 n130 n 130 (n=130 2 4 %SML, SML (%SML) (ΔZ analyzed study 1 7days days 7 each n=240 n240 240 (n=240 20 drips IEPS, IEPS) Sa (Sa evaluated baseline p 0.05 005 0 05 p<0.05. p005 p<0.05 .

ABSTRACT Objective: To assess the in-vitro effect of single applications of CPP-ACP pastes and different fluoridated solutions on the prevention of dental caries around orthodontic brackets. Material and Methods: Tooth/bracket sets (n=65) were immersed in artificial saliva (1h at 37ºC) and randomly subjected to single applications (100µL; 1min) of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP emulsion), CPP-ACP with fluoride (CPP-ACPF emulsion), solutions of titanium tetrafluoride (TiF4) or sodium fluoride (NaF), or no treatment (CG). Multispecies biofilm (5 x 105 CFU/mL) was formed in the presence of 2% sucrose. After 24 h, the pH and the concentration of total soluble fluoride (TSF) were analyzed by culture medium. The presence of active white spot lesions (WSL) evaluated by macroscopic examination and the percent surface mineral loss (%SML) were analyzed. Also, the topography of enamel was detected by analysis of scanning electron microscopy (SEM). The data was assessed by chi-square, Kruskal-Wallis, and Mann-Whitney tests (p < 0.05). Results: Fluoride-containing compounds led to a smaller pH reduction than did CPP-ACP and CG (p<0.05). There was difference in TSF between the groups (p<0.05), denoted as TiF4> NaF > CPP-ACPF > CPP-ACP > CG. Regarding the presence of WSL and %SML, the NaF group obtained lower values (p<0.05), while TiF4 and CPP-ACPF were similar (p>0.05). SEM demonstrated that fluoride-free groups had a larger surface dissolution. Conclusion: Fluoridated groups including solutions and CPP-ACPF were more effective than CPP-ACP in reducing enamel demineralization around orthodontic brackets after a single application.

RESUMO Objetivo: Avaliar in-vitro o efeito de uma aplicação única de cremes dentais de CPP-ACP e diferentes soluções fluoretadas na prevenção da cárie dentária ao redor de braquetes ortodônticos Material e Métodos: O conjunto dentes/braquetes (n=65) foi imerso em saliva artificial (1h em 37°C) randomizado e submetido a tratamento único (100µL; 1 min) de emulsão de fosfopeptídeo de caseína-fosfato de cálcio amorfo (CPP-ACP) e CPP-ACP associado ao flúor (CPP-ACPF); soluções de tetrafluoreto de titânio (TiF4) e fluoreto de sódio (NaF); e ausência de tratamento (GC). Biofilmes multiespécie (5 x 105 CFU/mL) foram formados na presença de sacarose a 2%. Após 24h, o pH e a concentração de fluoreto solúvel total (FST) foram analisados pelo meio de cultura. Foram avaliadas a presença de lesões de mancha branca (LMB), por meio da análise de macroscopia visual, e a porcentagem de perda de dureza (%PD). Também foi verificada a topografia do esmalte, usando microscopia eletrônica de varredura (MEV). Os dados foram analisados pelos testes Qui-quadrado, Kruskal-Wallis e Mann-Whitney (p < 0,05). Resultados: Os compostos contendo flúor levaram a uma redução do pH menor do que o CPP-ACP e GC (p<0,05). Houve diferença no FST entre os grupos (p <0,05), sendo TiF4> NaF > CPP-ACPF > CPP-ACP > GC. Quanto à presença de LMB e à %PD, o grupo NaF obteve os menores valores (p<0,05), enquanto TiF4 e CPP-ACPF foram semelhantes (p> 0,05). A MEV demonstrou que os grupos sem flúor tiveram uma dissolução superficial maior. Conclusão: Os grupos fluoretados, incluindo soluções e CPP-ACPF, foram mais eficazes do que o CPP-ACP sem flúor na redução da desmineralização do esmalte ao redor dos braquetes ortodônticos após uma única aplicação.

ABSTRACT Objective To describe and evaluate the xylitol products’ applicability and its effects in the health area worldwide utilizing a bibliometric analysis from randomized controlled trials (RCT) with humans. Material and Methods Electronic searches were carried out in Medline/PubMed, Scopus, Cochrane Library, Web of Science, and VHL databases. The main data extracted were: year, area of applicability, type of treatment, country, journal, xylitol posology and concentration, presentation form, outcomes, and effects. Results From 1476 studies, 257 were included. These studies were published between 1973-2021. The majority was carried out in dentistry (73.9%) and under preventive treatment (67.4%). These studies were developed in the USA (15.4%) and published in Caries Research (6.6%). The posology and concentration ranged between 0.004-67 g/day and 0.002-100%, respectively. The xylitol is usually used in the chewing gum form (44.0%), and for antimicrobial activity evaluation (38.5%). A positive effect was observed in 204 studies (79.3%) and was associated with xylitol concentration ≥ 15(p=0.007). Side effects were reported in 8.2and were associated with posology ≥ 5 g/day (p=0.03). Conclusion Most studies with xylitol were conducted to prevent diseases in the dentistry field. The chewing gum form and antimicrobial activity evaluation were more frequent. Most xylitol products have a positive effect, and few studies report side effects.

Abstract Objective: To verify the relationship between the types of feeding and presence of harmful oral habits (HOH) in children with cleft lip (CL), palate (CP) and cleft lip and palate (CLP), as well as to compare the different types of cleft to each other. Material and Methods: A form was applied to the parents of 162 children (3-5 years old), addressing the following variables: gender, cleft type, age, socioeconomic conditions, type of breastfeeding, presence of HOH, and the parents' knowledge about the consequences of oral habits. The data obtained were analyzed by chi-square test (p<0.05). Results: The majority of children (83.3%) were bottle-fed and 12.3% were exclusively maternal breastfed. The main reason for weaning was the presence of cleft (59.9%). Breastfeeding was significantly higher in children with CL (75%) in comparison with CP (20%) and CLP (5%) (p<0.001). Children with CLP were 12 times more likely to be bottle-fed than children with CL (OR=12.21; CI=4.09-36.45). The prevalence of HOH was 37%. Sociodemographic characteristics were not associated with the presence of HOH (p>0.05). The type of feeding and cleft were not decisive to present some type of HOH (p>0.05) and 87% of parents stated that HOH could lead to serious complications of tooth misalignment. Conclusion: The type of feeding and fissure did not determine the acquisition of harmful oral habits in children with cleft. However, the greater the fissure's complexity, the lesser the chance of children receiving exclusive breastfeeding.

Abstract Objective: To evaluate factors associated with the caregivers’ perception of the oral health of children and adolescents with cerebral palsy. Material and Methods: A cross-sectional study was carried out with 80 children and adolescents with cerebral palsy aged 2-18 years, registered at a reference institution and their respective caregivers. Caregivers provided socioeconomic, systemic and health perception and access to dental services data. A calibrated researcher (Kappa=0.75-0.98) performed oral examinations using DMF-T, dmf-t, dental trauma, gingival bleeding index, community periodontal index, malocclusion index and the dental aesthetic index. The Poisson Regression was used (α=0.05) Results: According to the caregivers’ perception, the oral health reports of children and adolescents with cerebral palsy considered good and poor was 73.8% and 26.3%, respectively. The poor oral health perception is associated with the presence of dental caries in anterior teeth (PR 1.34, 95% CI=1.11-1.63) and bleeding during tooth brushing (PR 1.20, 95% CI=1.04-1.40) Conclusion: Children and adolescents with cerebral palsy who presented lesions of caries in the anterior teeth and gingival bleeding during tooth brushing, more frequently, had poor oral health by their caregivers.

Abstract Objective: To evaluate in vitro the presence of fluoride in saliva after applying professional use products on the surface of dental enamel. Material and Methods: Experimental groups were composed by: Cariostatic 12% (CA), Fluoridated Varnish 5% (FV), Fluorine Acidulate Gel 1.23% (AG) and Fluorine Neutral Gel 2% (NG). Fluoridated dentifrice (FD) and Artificial Saliva (AS) were used as controls. Products (10 μL) were applied to the surface of bovine enamel blocks (4×4×1 mm, n = 18) and immersed in 10 mL of artificial saliva at room temperature. Aliquots of artificial saliva (750 μL) of each sample were collected 1, 2, 4, 8, 24 and 48 hours after application of the products. Analyses were performed in triplicate, using a fluoride ion-specific electrode coupled to a potentiometer. The equipment was calibrated using a standard curve for fluoride analysis from 0.125 to 64 μgF-/mL. Results: Greater fluoride concentration (μgF-/mL) was observed after 1h application, as follows: 197.40 (NG), 172.21 (AG), 20.25 (CA), 14.49 (FV) e 11.81 (FD). Fluoride concentration increased overtime for all groups. After 48h, the following fluoride concentrations were assessed: 428.12 (AG), 267.25 (NG), 65.36 (FV), and 62.52 (CA). Conclusion: Greater fluoride release was observed for AG and NG groups, mostly after 1h application.

Abstract Objective: To evaluate in vitro the effect of a red propolis ethanolic extract (RPE) in the prevention of growth of a cariogenic biofilm and its cytotoxic potential. Material and Methods: Minimum inhibitory and bactericidal concentrations (MIC and MBC) of RPE against Streptococcus mutans and Lactobacillus casei were determined. The cytotoxic potential of 0.4% RPE in oral fibroblasts was observed after 1, 3 and 5 min of contact. Cellulose membrane disks (13 mm, N=12) were used for biofilm formation (24 h) of S. mutans and L. casei, which were treated (1 min) with 0.4% RPE or 0.12% Chlorhexidine (CHX). The control group of biofilm formation was not submitted to any treatment. Serial dilutions were then made to evaluate microbial viability. Descriptive data analysis and, for microbial viability, Mann Whitney test were performed (p≤0.05). Results: RPE showed similar MIC and MBC (4.46 mg/mL) against S. mutans and, for L. casei, they were 8.92 mg/mL (MIC) and 17.85 mg/mL (MBC). CHX presented MIC and MBC <0.00002 mg/mL for S. mutans and 0.00047 mg/mL for L. casei. After 1, 3 and 5 min, the RPE exhibited, respectively, 69.38%, 43.91% and 40.36% of viable cells. The RPE (6.55) and CHX (6.87) presented similar efficacy to reduce the total number of viable bacteria (p>0.05). Regarding the total number of viable bacteria (Log10 CFU/mL), the RPE (6.55) and CHX (6.87) presented similar efficacy (p>0.05). Conclusion: Red propolis extract showed antibacterial activity against the tested strains, exhibited acceptable cytotoxicity and reduced the colonization of S. mutans and L. casei in a biofilm membrane model.
