Abstract Objectives This study aimed to analyze the cost-effectiveness of whitening toothpastes and at-home bleaching for the treatment of tooth discoloration. Methodology A cost-effectiveness economic analysis was conducted, and eight randomized clinical trials were selected based on the whitening agent product used: blue covarine dentifrices (BCD), hydrogen peroxide dentifrices (HPD), dentifrices without bleaching agents (CD, negative control), and 10% carbamide peroxide (CP10, positive control) for at-home bleaching. The consumer/patient perspective was adopted, macro-costing techniques were used and a decision tree model was performed considering the costs in the American and Brazilian markets. The color change evaluation (ΔE*ab) was used to calculate the effectiveness of tooth bleaching. A probabilistic analysis was performed using a Monte Carlo simulation and incremental cost-effectiveness ratios were obtained. Results CP10 resulted in the highest cost-effectiveness compared to the use of dentifrices in both markets. In Brazil, HPD was more cost-effective than BCD and CD. In the US, the increased costs of HPD and BCD did not generate any whitening benefit compared to CD. Conclusions CP10 was more cost-effective than BCD and HPD for tooth bleaching from the perspectives of the Brazilian and American markets.

ABSTRACT Objective: To measure the costs of preventive and therapeutic protocols of Photobiomodulation (PBM) for oral mucositis (OM) and their budgetary impact on Brazil’s Ministry of Health (BMH). Material and Methods: A partial economic analysis was performed to estimate the costs using a bottom-up approach from a social perspective. Monetary values were assigned in Brazilian reais (BRL). The costs of the preventive protocol were calculated for five, 30, and 33 consecutive PBM sessions, depending on the antineoplastic treatment instituted. The costs of the therapeutic protocol were calculated for 5 or 10 sessions. The annual financial and budgetary impact was calculated considering the groups of oncologic patients with a higher risk of development of OM, such as those with head and neck and hematological cancer and pediatric patients. Results: The cost of a PBM session was estimated at BRL 23.75. The financial impact of providing one preventive protocol per year for all oncologic patients would be BRL 14,282,680.00, 0.030% of the estimated budget for hospital and outpatient care of the BMH in 2022. The financial and budgetary impacts of providing one treatment for OM for all patients in one year would be BRL 2,225,630.31 (0.005%, most optimistic scenario) and BRL 4,451,355.63 (0.009%, most pessimistic scenario). Conclusion: The budgetary impact of implementing PBM protocols in the Brazilian Healthcare System is small, even in a pessimistic scenario. Objective (PBM (OM Brazils Brazil s BMH. .

ABSTRACT BACKGROUND AND OBJECTIVES: The extraction of third molars can lead to undesired effects such as pain, trismus, and edema, necessitating preemptive therapy to alleviate these effects. For this purpose, an economic evaluation was conducted to analyze the cost-effectiveness of preemptive drugs used in the extraction of third molars. METHODS: Costs were obtained from a market survey. Effectiveness measures were limitation of interincisal distance and postoperative pain, obtained from randomized clinical trials in the literature. For both models, a Monte Carlo simulation generated a hypothetical cohort of a thousand individuals, considering a 5% variation in estimates. The evaluated therapies were dexamethasone 8 mg (DX8); methylprednisolone 40 mg (MP); diclofenac 50 mg associated with tramadol 50 mg (DCTR); and dexamethasone 4mg associated with tramadol 50 mg (DXTR). RESULTS: MP and DCTR therapies were dominated in all scenarios. For the reduction of postoperative pain, DXTR treatment showed the best cost-benefit, with a net monetary benefit (NMB) gain of 31.10% compared to the lowest-cost treatment (DX, R$ 1.76). Considering the reduction in limitation of interincisal distance, DXTR medication presented higher cost-benefit compared to DX8 (NMB gain = 18.25%), being a preferred option alongside DX8. CONCLUSION: In the extraction of third molars, preemptive administration of dexamethasone 4mg associated with tramadol 50mg is the preferred cost-effective option to reduce postoperative pain and limitation of interincisal distance after 48 hours.

RESUMO JUSTIFICATIVA E OBJETIVOS: A exodontia de terceiros molares pode acarretar efeitos indesejados, como dor, trismo e edema, sendo necessário ofertar uma terapia preemptiva para amenizá-los. Para tal, realizou-se uma avaliação econômica para analisar o custo-efetividade de fármacos preemptivos utilizados na exodontia de terceiros molares. MÉTODOS: Os custos foram obtidos a partir de uma pesquisa de mercado. As medidas de efetividade foram: limitação da distância interincisal e dor pós-operatória, sendo obtidas em ensaios clínicos randomizados da literatura. Para os dois modelos, uma simulação de Monte Carlo gerou uma coorte hipotética de mil indivíduos, considerando uma variação de 5% das estimativas. As terapias avaliadas foram: dexametasona 8 mg (DX8); metilprednisolona 40 mg (MP); diclofenaco 50 mg associado a tramadol 50 mg (DCTR); e dexametasona 4 mg associada a tramadol 50 mg (DXTR). RESULTADOS: As terapias com MP e DCTR foram dominadas em todos os cenários. Para redução da dor pós-operatória, o tratamento com DXTR apresentou o melhor custo-benefício, com ganho de benefício monetário líquido (NMB) de 31,10% comparado ao tratamento de menor custo (DX, R$ 1,76). Considerando a redução da limitação da distância interincisal, o fármaco DXTR apresentou maior custo-benefício em relação à DX8 (ganho de NMB = 18,25%), sendo uma opção de escolha junto a DX8. CONCLUSÃO: Na exodontia de terceiros molares, a administração preemptiva de dexametasona 4 mg associada com tramadol 50 mg é a opção de escolha, do ponto de vista de custo-efetividade, para reduzir a dor pós-operatória e limitação da distância interincisal após 48 horas.

ABSTRACT Objective: To assess the comprehension of dentists in Primary Health Care (PHC) regarding the interplay between obesity and periodontitis and evaluate the presence of practical approaches for managing these patients. Material and Methods: For this cross-sectional study, 187 general dental practitioners from different regions of Brazil were selected by convenience. A specific instrument was developed to assess the knowledge and practices of PHC dentists concerning this topic. The data underwent descriptive and analytical statistical analyses, followed by Poisson regression analysis with robust variance to test associations. Results: Regarding knowledge, most dentists have a limited understanding of the link between obesity and periodontitis, despite 43% recognizing the higher susceptibility of individuals with obesity to oral issues. About 20% of professionals considered their knowledge “adequate." Better knowledge was observed among dentists who worked only in the public sector, which has concluded some post-graduation (p<0.05). Regarding the professional's practical conduct, around 57% of the dentists do not diagnose obesity, and 64% of the professionals do not refer these patients to a nutritionist. Conclusion: The study's outcomes underscore the prevailing lack of awareness among this sampled group of dental practitioners concerning the association between obesity and periodontitis. Furthermore, it was observed that multidisciplinary treatment for obese patients within the realm of PHC is generally underperformed.

ABSTRACT Objective: To evaluate the cost-effectiveness of single-tooth rehabilitation options with dental implants associated with a prosthetic crown (I+C) compared to a fixed partial denture (FPD). Material and Methods: A rapid review was carried out to identify the costs (expressed in US$) and effectiveness (expressed through success rate). Bibliographic searches retrieved 1,447 records, of which 19 studies of type randomized clinical trials were selected to collect cost and effectiveness data. Markov economic models were used to simulate hypothetical 15-year cohorts with 2000 patients using cost and effectiveness data from the rapid review under the perspective of private practice. Results: The average costs of I+C and FPD treatments were US$ 3,432.23 and US$ 3,322.52, respectively. The average effectiveness of I+C was 88.33%, with a mean follow-up time of 9.33 years, and FPD had an average yearly success rate of 82.14%, with a mean follow-up time of 11.89 years. The I+C treatment has an incremental cost-effectiveness ratio (RCEI) of US$ 170.88 compared to FPD. Conclusion: Both I+C and FPD rehabilitation options are cost-effective; I+C rehabilitation has a higher cost and greater effectiveness, being the recommended option if the patient with no contraindication.

Abstract Experimental models that consider host-pathogen interactions are relevant for improving knowledge about oral candidiasis. The aim of this study was to assess the epithelial immune responses, Candida penetration of cell monolayers, and virulence during mixed species culture infections. Single species cultures of Candida albicans and mixed cultures (C. albicans, Streptococcus mutans, and Streptococcus sanguinis) were used to infect monolayers of HaCaT and FaDu ATCC HTB-43 cells for 12 h. After infection, IL-18 and IL-34 gene expression was measured to assess epithelial cell immune responses, and lactate dehydrogenase (LDH) activity was measured as an indicator of cell damage. Microscopy determined C. albicans morphology and penetration of fungal cells through the keratinocyte monolayer. Monolayers devoid of infection served as controls. Data were analyzed by an ANOVA one-way test followed by Tukey’s post-hoc test (α = 0.05). The results found that IL-18 and IL-34 gene expression and LDH activity were significantly (p < 0.05) upregulated for both cell lines exposed to mixed species cultures compared with C. albicans alone. Candida albicans yeast and hyphae were evident in C. albicans only infections. In contrast, monolayers infected by C. albicans, S. mutans, and S. sanguinis exhibited higher microbial invasion with several hyphal aggregates detected. The presence of streptococci in C. albicans infection enhances the virulence and pathogenicity of the fungus with associated increased immune responses and tissue damage. Extrapolation of these findings to oral infection would indicate the added potential benefit of managing bacterial components of biofilms during treatment. hostpathogen host pathogen candidiasis infections C (C mutans HTB43 HTB 43 HTB-4 1 h IL18 IL 18 IL-1 IL34 34 IL-3 (LDH damage monolayer controls oneway one way Tukeys Tukey s posthoc post hoc α 0.05. 005 0.05 . 0 05 p alone contrast S detected treatment HTB4 4 HTB- IL1 IL- IL3 3 00 0.0 0.

Resumo O objetivo deste estudo foi avaliar a resposta epithelial imune, a colonização da Candida albicans em monocamadas celulares e sua virulência em resposta a infecções de culturas de biofilme multiespécie. Culturas de biofilme monoespécie de C. albicans e culturas mistas (C. albicans, Streptococcus mutans e Streptococcus sanguinis) foram utilizadas para infectar monocamadas de células HaCaT e FaDu por 12 h. Após a infecção, a expressão dos genes IL-18 e IL-34 foi medida para avaliar as respostas imunes das células epiteliais. A atividade da lactato desidrogenase (LDH) foi medida como um indicador de dano celular. A microscopia determinou a morfologia de C. albicans e a penetração das células fúngicas através da monocamada de queratinócitos. Monocamadas em que não houve infecção serviram como controles. Os dados foram analisados por um teste ANOVA one-way seguido pelo teste post-hoc de Tukey (α = 0,05). Os resultados demonstraram que a expressão gênica de IL-18 e IL-34 e a atividade de LDH foram (p < 0,05) reguladas positivamente para ambas as linhagens de células expostas a culturas de espécies mistas em comparação com C. albicans isoladamente. Leveduras de C.albicans e hifas foram evidentes em infecções apenas por C. albicans. Entretanto, monocamadas infectadas por C. albicans, S. mutans e S. sanguinis exibiram maior invasão microbiana com vários agregados de hifas detectados. Dessa maneira, a presença de estreptococos na infecção por C. albicans aumentou a virulência e a patogenicidade do fungo com respostas imunes aumentadas associadas a danos nos tecidos. A extrapolação desses achados para a infecção oral indicaria o potencial benéfico do controle dos componentes bacterianos em biofilmes durante a terapia da candidíase imune multiespécie C (C 1 h IL18 IL 18 IL-1 IL34 34 IL-3 epiteliais (LDH celular queratinócitos controles oneway one way posthoc post hoc α 0,05. 005 0,05 . 0 05 p isoladamente Calbicans Entretanto S detectados maneira tecidos IL1 IL- IL3 3 00 0,0 0,

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 Schinus terebinthifolia Raddi green fruits essential oil (EO) was evaluated regarding its phytochemical profile, antimicrobial and cytotoxic activities, and toxicity. Gas chromatography with mass spectrometry was applied to identify its constituents, thereafter the minimum inhibitory concentration, minimum bactericidal and fungicidal concentrations, and its antibiofilm activity were evaluated. The EO cytotoxicity was assessed in tumor and non-tumor human cells, and in vivo toxicity was evaluated in a Galleria mellonella model. The major constituents of S. terebinthifolia EO were alpha-phellandrene and beta-phellandrene. The EO had a weak activity against all strains of Candida albicans (MIC 1000μg/mL) and had no activity against non-albicans strains, bacteria, and C. albicans biofilm. Cytostatic activity against all tumor cell lines was shown. Additionally, cell viability remained at EO concentrations up to 62.5 μg/mL. At 16 mg/mL, 50% hemolysis was observed, and it had low toxicity in vivo. Overall, the S. terebinthifolia EO was characterized by low antimicrobial and antibiofilm activities, with no evidence of toxicity to human tumor and non-tumor cells.

Resumo Estimar os custos e a compatibilidade dos incentivos públicos de duas tecnologias para o tratamento da mandíbula edêntula: prótese total convencional (PTC) e overdenture retida por dois implantes (OD). Este estudo consistiu em uma avaliação econômica parcial, com abordagem “bottom-up” para o cálculo dos custos diretos. As estimativas levaram em consideração o número de consultas, proporção de materiais, equipamentos, vida útil dos instrumentais e recursos humanos. Os custos foram baseados no painel de preços do Ministério da Economia do Brasil e informações complementares foram obtidas de um painel de especialistas. Uma análise de sensibilidade foi baseada na variação de 20% dos custos. Os custos da PTC foram estimados em R$ 189,89 (cenário base) com variação entre R$ 151,91 e R$ 227,89 na análise de sensibilidade. Os custos da OD foram R$ 663,05 (variando de R$ 795,66 a R$ 530,44). O Ministério da Saúde cobre apropriadamente os custos de ambas as tecnologias nos cenários base e mais otimista. Ambas as tecnologias apresentaram custos dentro dos limites dos incentivos públicos recebidos. As tecnologias são economicamente viáveis e devem ser induzidas por políticas públicas diante do impacto positivo em vários domínios funcionais da saúde.

Abstract This study aimed to estimate cost and compatibility with public financial incentives of two technologies for treating the edentulous mandible: lower complete dentures (CD) and overdentures retained by two dental implants (OD). This study consisted of a partial economic evaluation, with a micro-costing bottom-up approach for the calculation of direct costs. The estimates involved the number of consultations, proportion of materials, equipment, instruments’ lifetime, and human resources, described in the price panel website of the Ministry of Economy in Brazil. Complementary information was obtained from a panel of experts. A sensitivity analysis was based on 20% variation. The estimated cost of a CD was R$ 189.89 (base scenario), and this varied between R$ 151.91 and R$ 227.89 according to sensibility analysis. The cost of an OD was R$ 663.05 (ranging from R$ 795.66 to R$ 530.44 - 1US=R$ 3.80/July 2019). The Ministry of Health covers appropriately the costs of the CD and OD. Both technologies showed costs that are within the limits of financial public incentives obtained by municipalities. The technologies are economically viable and should be induced through public policies due to their positive impacts on several functional domains of health.

RESUMO Este estudo teve como objetivo avaliar o efeito in vitro de uma única aplicação de soluções experimentais de nanocompósitos na prevenção de cárie dentária em braquetes ortodônticos. Os espécimes foram expostos a nanocompósitos de sílica mesoporosa (MS) contendo fluoreto por associação com tetrafluoreto de titânio (TiF4) ou fluoreto de sódio (NaF). Os nanocompósitos também podem conter cálcio e os grupos foram descritos como MSCaTiF4, MSTiF4, MSCaNaF, MSNaF e controles (TiF4 e NaF). Os espécimes foram submetidos à formação de um biofilme multiespécie para gerar um desafio cariogênico. Após 24h, o pH e a concentração de flúor solúvel total do meio de cultura foram avaliados. A perda mineral foi avaliada pela porcentagem de perda mineral superficial (% SML), variação do volume mineral (ΔZ) do esmalte interno e microscopia de luz polarizada (PL). A rugosidade superficial linear (Ra) e volumétrica (Sa) e a microscopia eletrônica de varredura (MEV) foram utilizadas para avaliar a topografia do esmalte. As análises estatísticas foram realizadas considerando p <0,05. MSNaF apresentou o maior valor de pH do meio de cultura após o desafio cariogênico, semelhante ao MSTiF4. Todas as soluções de nanocompósitos liberaram menos flúor do que seus controles NaF e TiF4 (p <0,05). Todas as soluções de nanocompósitos apresentaram% SML menor em comparação com seus respectivos grupos de controle (p <0,05). Ra, Sa e ΔZ menores foram observados para os grupos experimentais em comparação ao TiF4 (p <0,05). Os resultados foram confirmados por análises PL e SEM. As soluções experimentais de nanocompósitos contribuíram para a menor desmineralização do esmalte ao redor dos braquetes ortodônticos.

Abstract This study aimed to evaluate the in vitro effect of a single application of experimental nanocomposite solutions on the prevention of dental caries around orthodontic brackets. The specimens were exposed to mesoporous silica (MS) nanocomposites containing fluoride by association with titanium tetrafluoride (TiF4) or sodium fluoride (NaF). Nanocomposites also could contain calcium and groups were described as MSCaTiF4, MSTiF4, MSCaNaF, MSNaF, and controls (TiF4, and NaF). Specimens were subjected to the formation of a multispecies biofilm to generate a cariogenic challenge. After 24h, both pH and total soluble fluoride concentration of the culture medium were assessed. Mineral loss was evaluated by percentage of surface mineral loss (%SML), mineral volume variation (ΔZ) of inner enamel and polarized light microscopy (PL). Linear (Ra) and volumetric (Sa) surface roughness and scanning electronic microscopy (SEM) were used to assess enamel topography. Statistical analyses were conducted considering p<0.05. MSNaF had the highest value of culture medium pH after cariogenic challenge, similarly to MSTiF4. All nanocomposite solutions released less fluoride than their controls NaF and TiF4 (p<0.05). All nanocomposite solutions presented lower %SML compared to their respective control groups (p<0.05). Lower Ra, Sa and ΔZ were observed for experimental groups compared to TiF4 (p<0.05). The results were confirmed by PL and SEM analysis. The experimental nanocomposite solutions contributed for lower enamel demineralization around orthodontic brackets.

Objective: To investigate factors associated with non-access to oral health in Brazil. Methods: Cross-sectional study that analyzed data from the external evaluation of the National Program to Improve Access and Quality (2014 and 2018), using hierarchical multivariate logistic regression. Non-access category was defined as the situation in which user was unable to make an appointment with a dentist. Results: We analyzed data from 37.262 individuals (2014 sample) and 117.570 people (2018 sample). A greater chance of non-access was found for those who: live in more unequal municipalities and with less oral health coverage, whose travel time to the unit is more than 11 minutes; female, aged between 25 and 39 years and whose income was up to 1 minimum wage. Conclusion: Non-access was associated with municipal factors such as grater inequality; organizational factors such as less coverage and travel time to the unit; and individual factors such as sex, age and income.

Objetivo: Investigar os fatores associados ao não acesso em saúde bucal no Brasil. Métodos: Estudo transversal, sobre dados da avaliação externa do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica, em 2014 e 2018, mediante regressão logística multivariada hierarquizada. Definiu-se como ‘não acesso’ quando o usuário não consegue marcar consulta com cirurgião-dentista. Resultados: Analisou-se dados de 37.262 indivíduos do segundo ciclo (2014) e 117.570 do terceiro ciclo (2018). Maior chance de não acesso ocorreu para residentes em municípios mais desiguais e com menor cobertura de saúde bucal, deslocamento para a unidade de saúde superior a 11 minutos, sexo feminino, idade entre 25 e 39 anos e renda de até 1 salário mínimo. Conclusão: O não acesso associou-se a fatores municipais, como maior desigualdade; fatores organizacionais, como menor cobertura e tempo de deslocamento até a unidade; e fatores individuais, como sexo, idade e renda

RESUMO A rede de atenção à Saúde Bucal (SB) se ampliou com a Política Nacional de Saúde Bucal, sendo os indicadores ferramentas para avaliar conquistas ou necessidade de mudanças. Este trabalho objetivou analisar indicadores de SB da Atenção Básica por tipo de organização das unidades de saúde em Recife, 2018. Trata-se de um estudo transversal, de natureza descritiva e analítica com base em dados secundários. Analisou-se a associação entre tipos de organização da Atenção Básica (Unidade de Saúde da Família - USF; Upinha e Unidade Básica Tradicional - UBT) e indicadores assistenciais de SB, através dos testes qui-quadrado e Kruskal-Wallis (p<0,05). A cobertura de primeira consulta odontológica e os procedimentos odontológicos per capita apresentaram mediana maior nas UBT, 31,8% (p=0,00) e 0,6 (p=0,127), respectivamente. A proporção de exodontia e procedimentos clínicos foi maior nas USF com mediana 8,2% (p=0,703). As USF foram as que realizaram o maior número de atividades coletivas de escovação dental supervisionada (45,3%, p=0,082) e aplicação de flúor (44,6%, p=0,174). Conclui-se que as UBT apresentaram melhores resultados nos indicadores relacionados ao acesso ao tratamento clínico e as USF realizaram mais ações coletivas de prevenção.

ABSTRACT The Oral Health care network (OH) has expanded with the National Oral Health Policy, and the indicators are tools to assess achievements or the need for changes. This study aimed to analyze the OH indicators of Primary Care Basic by health units organization type in Recife, 2018. This is a cross-sectional, quantitative, descriptive and analytical study, based on secondary data. The association between organization type of Primary Care (Family Health Unity/USF; Upinha and Traditional Basic Health Unit/UBT) and OH assistance indicators was analyzed using the chi-square and Kruskal-Wallis tests (p<0,05). The first dental appointment coverage and the average number of procedures per capita showed a higher median in the UBT, 31,8% (p=0,00) and 0,6 (p=0,127), respectively. The tooth extraction proportion was higher in the USF, with a median of 8,2% (p=0,703). The USF were the ones that performed the largest number of collective activities of supervised tooth brushing (45.3%, p=0.082) and fluoride application (44.6%, p=0.174). It is concluded that the UBT showed better results in the indicators related to access to clinical treatment and the USF performed more collective activities.
