It has antimicrobial activity and teeth whitening effect too

Efeito de dentifrícios com alta concentração de flúor na remineralização de substrato dentário com cárie artificial / Effect of toothpaste with high fluoride concentration on remineralization of dental substrate with artificial caries

Introduction: fluoride toothpaste is widely used by the population. Objective: dentifrices with a high concentration of sodium fluoride and the presence of tricalcium phosphate were developed, providing additional protection to patients vulnerable to the development of caries. This study aimed to evaluate the influence of different dentifrices on the surface and internal hardness and enamel wear after artificial caries, pH cycling, and toothbrushing. Material and method: enamel blocks (4x4 mm) were obtained from 20 bovine teeth. The specimens were submitted to artificial caries lesion and then to pH cycling and brushing according to the dentifrice: Colgate Total 12 and Clinpro + Tricalcium Phosphate. Result: after this period, they were submitted to analysis of superficial and internal hardness and profilometry. Scanning Electron Microscopy (SEM) was performed. The data obtained were evaluated by one-way Analysis of Variance (ANOVA) to evaluate the mineral recovery and profilometry, and two-way repeated measures ANOVA to evaluate the superficial and internal hardness. Conclusion: analyzing the surface hardness, after caries induction, there was a significant reduction in hardness that was partially recovered regardless of the dentifrice used. For internal hardness, Clinpro obtained lower values on the control side and up to 90 micrometers on the test side. As for profilometry, Colgate Total 12 showed greater wear when compared to Clinpro. It was concluded that Clinpro promoted lower internal hardness, however, Colgate Total 12 resulted in greater surface wear of tooth enamel.

Conclusão: analisando a dureza superficial, após a indução da cárie houve uma redução significativa na dureza que foi parcialmente recuperada independente do dentifrício utilizado. Para dureza interna, Clinpro obteve valores menores no lado controle e até 90 micrômetros no lado teste. Quanto à perfilometria, o Colgate Total 12 apresentou maior desgaste quando comparado ao Clinpro. Concluiu-se que Clinpro promoveu menor dureza interna, porém, o Colgate Total 12 resultou em maior desgaste superficial do esmalte dentário.

A comparative study to evaluate the effects of antibiotics, plant extracts and fluoride-based toothpaste on the oral pathogens isolated from patients with gum diseases in Pakistan / Um estudo comparativo para avaliar os efeitos de antibióticos, extratos vegetais e creme dental à base de flúor sobre os patógenos orais isolados de pacientes com doenças gengivais no Paquistão

Abstract Oral diseases caused by various microorganisms are common around the world. Scientific research has now been focusing on novel medicines to overcome bacterial resistance and antibiotics side effects; therefore, the current study was designed to assess the efficacy of certain antibiotics, toothpaste, and medicinal plant extracts (Ajuga bracteosa and Curcuma longa) versus the bacterial pathogens isolated from the human oral cavity. A total of 130 samples were collected from Khyber Teaching Hospital Peshawar, Pakistan, among those 27 species isolated, and eight bacterial species were identified from the samples. Among all the bacterial species, Staphylococcus aureus (29.62%) and Proteus mirabilis (22.2%) were found to be more prevalent oral pathogens. In comparison, the least pervasive microbes were Proteus vulgaris, Shigella sonnei, Escherichia coli and Aeromonas hydrophila. The study also suggested that dental problems were more prevalent in males (41-50 years of age) than females. Among the eight antibiotics used in the study, the most promising results were shown by Foxicillin against A. hydrophila. The survey of TP1 revealed that it showed more potent antagonist activity against Proteus vulgaris as compared TP2 and TP3 that might be due to the high content of fluoride. The Curcuma longa showed more significant activity than Ajuga bracteosa (Stem, leaves and root) extracts. The data obtained through this study revealed that antibiotics were more effective for oral bacterial pathogens than toothpaste and plant extracts which showed moderate and low activity, respectively. Therefore, it is suggested that the active compounds in individual medicinal plants like Curcuma longa and Ajuga bracteosa could replace the antibiotics when used in daily routine as tooth cleansers or mouth rinses.

Resumo As doenças bucais causadas por vários microrganismos são comuns em todo o mundo. A pesquisa científica agora tem se concentrado em novos medicamentos para superar a resistência bacteriana e os efeitos colaterais dos antibióticos; portanto, o presente estudo foi desenhado para avaliar a eficácia de certos antibióticos, pasta de dente e extratos de plantas medicinais (Ajuga bracteosa e Curcuma longa) contra os patógenos bacterianos isolados da cavidade oral humana. No total, 130 amostras foram coletadas do Khyber Teaching Hospital Peshawar, Paquistão, entre essas, 27 espécies foram isoladas e oito espécies bacterianas foram identificadas a partir das amostras. Entre todas as espécies bacterianas, Staphylococcus aureus (29.62%) e Proteus mirabilis (22.2%) foram os patógenos orais mais prevalentes. Em comparação, os micróbios menos difundidos foram Proteus vulgaris, Shigella sonnei, Escherichia coli e Aeromonas hydrophila. O estudo também sugeriu que os problemas dentários eram mais prevalentes em homens (41-50 anos de idade) do que em mulheres. Entre os oito antibióticos usados ​​no estudo, os resultados mais promissores foram mostrados pelo Foxicillin contra A. hydrophila. A pesquisa de TP1 revelou que ele mostrou atividade antagonista mais potente contra Proteus vulgaris em comparação a TP2 e TP3, o que pode ser devido ao alto teor de flúor. A Curcuma longa apresentou atividade mais significativa em relação aos extratos de Ajuga bracteosa (caule, folhas e raiz). Os dados obtidos neste estudo revelaram que os antibióticos foram mais eficazes para os patógenos bacterianos orais do que os dentifrícios e os extratos vegetais que apresentaram atividade moderada e baixa, respectivamente. Portanto, sugere-se que os compostos ativos em plantas medicinais individuais como Curcuma longa e Ajuga bracteosa possam substituir os antibióticos quando usados ​​na rotina diária como limpadores de dentes ou enxaguatórios bucais.

Introdução: As gengivites são condições comuns em todas as populações, independente da faixa-etária. A indicação de agentes químicos como antissépticos bucais mostra-se importante prevenindo a formação de novo biofilme na superfície dental. Extratos vegetais têm sido propostos como possibilidades terapêuticas interessantes devido as características antimicrobianas e imunomoduladoras de diversos fitoterápicos. Objetivo: Realizar um levantamento bibliográfico sobre o uso das plantas medicinais no controle do biofilme dental para tratamento e prevenção da gengivite. Metodologia: foi realizada uma análise de dados secundários, através de uma revisão da literatura sobre a utilização de plantas medicinais na prevenção e tratamento da gengivite. Foram analisados artigos científicos publicados entre 2012 a 2021, obtidos nas bases eletrônicas de dados indexados no PubMed, Google Scholar, Lilacs e Scielo, que apresentaram resultados positivos e que tiveram a clorexidina como controle. Resultados: As informações obtidas foram apresentadas em três tabelas separando enxaguatórios e dentifrícios. Nos estudos que comparam colutórios à base de ervas com enxaguatório bucal com clorexidina 0,12%, em sua maioria, discorrem sobre a igualdade da eficácia na redução do biofilme dental e da gengivite. Nos dois trabalhos que avaliaram dentifrícios, pode-se notar que houve uma boa aceitação por parte dos pesquisados e não mostraram efeitos adversos. Conclusão: Os fitoterápicos são bem indicados como alternativas para manter a saúde gengival. Entretanto, devem ser realizados mais ensaios clínicos longitudinais para fundamentar seus efeitos a longo prazo, testando diferentes protocolos, concentrações e parâmetros clínicos de avaliação para esclarecer a relevância clínica destes produtos naturais no controle e tratamento da gengivite.

Introduction: Gingivitis is a common condition in all populations, regardless of age group. The indication of chemical agents such as mouthwashes prove to be important in preventing the formation of a new biofilm on the dental surface. Plant extracts have been proposed as interesting therapeutic possibilities due to the antimicrobial and immunomodulatory characteristics of several herbal medicines. Objective: To carry out a bibliographic survey on the use of medicinal plants in the control of dental biofilm for the treatment and prevention of gingivitis. Methodology: an analysis of secondary data was performed, through a literature review on the use of medicinal plants in the prevention and treatment of gingivitis. Scientific articles published between 2012 and 2021 were analyzed, from electronic databases indexed in PubMed, Google Scholar, Lilacs and Scielo, which presented positive results and which had chlorhexidine as a control. Results: The information was presented in three tables, two of which are separated between mouthwash and toothpaste. The herbal mouthwashes with 0.12% chlorhexidine found that most of them were equally effective in reducing plaque and gingivitis compared to the 0.12% chlorhexidine mouthwash. In the two studies that evaluated toothpastes, it can be noted that there was a good acceptance by those surveyed and they did not show adverse effects. Conclusion: Phytotherapics are well indicated as alternatives to maintain gingival health. However, further longitudinal clinical trials should be performed to substantiate their long-term effects, testing different protocols, concentrations and clinical evaluation parameters to clarify the clinical relevance of these natural products in the control and treatment of gingivitis.

Los extractos de plantas se han propuesto como interesantes posibilidades terapéuticas debido a las características antimicrobianas e inmunomoduladoras de varias hierbas medicinales. Objetivo: Realizar un estudio bibliográfico sobre el uso de plantas medicinales en el control del biofilm dental para el tratamiento y prevención de la gingivitis. Metodología: se realizó un análisis de datos secundarios, a través de una revisión bibliográfica sobre el uso de plantas medicinales en la prevención y tratamiento de la gingivitis. Se analizaron artículos científicos publicados entre 2012 y 2021, de bases de datos electrónicas indexadas en PubMed, Google Scholar, Lilacs y Scielo, que presentaran resultados positivos y que tuvieran clorhexidina como control. Resultados: La información se presentó en tres tablas, dos de ellas separadas entre colutorio y pasta dentífrica. En los enjuagues bucales a base de plantas con clorhexidina al 0,12% se observó que la mayoría de ellos eran igual de eficaces para reducir la placa y la gingivitis en comparación con el enjuague bucal con clorhexidina al 0,12%. En los dos estudios que evaluaron los dentífricos, puede observarse que hubo una buena aceptación por parte de los encuestados y no mostraron efectos adversos. Conclusiones: Los fitoterápicos están bien indicados como alternativas para mantener la salud gingival. Sin embargo, se deben realizar más ensayos clínicos longitudinales para corroborar sus efectos a largo plazo, probando diferentes protocolos, concentraciones y parámetros de evaluación clínica para aclarar la relevancia clínica de estos productos naturales en el control y tratamiento de la gingivitis.

A Pharmaceutico-Analytical and Antimicrobial Study of Trivargtrityadi Yoga (TTY)

In current scenario herbal formulations containing natural ingredients is more acceptable in public belief than chemical based synthetic formulations due to their safety and efficacy in reducing dental caries, pyorrhoea and preventing other dental and oral issues to which this generation is prone to. Clinically more effective and tolerable treatments should improve patient compliance with oral hygiene practices, further supporting medical professionals' efforts to avoid disease. Controlling the creation of dental plaque is the most efficient method of preventing the onset of dental disease. Microbes have an impact on its formation. Ayurveda recommends some daily use therapeutic procedures for the prevention and maintenance of oral health. These include: Pratisarana (gentle massage over tissue), Dant Dhavani (brushing), Jivha Lekhana (tongue scrapping) and Gandoosha (gargling) or oil pulling. The present study focused on preparation and validation of the classical formulation Trivargtrityadi yoga (TT yoga) which mentioned in Ashtang Sangraha by Acharya Vagbhata described in Dantadhawanacharya. It Contains Triphala, Trikatu, Trijatak and Kuth. These extracts have a variety of beneficial characteristics, including those that are anti-cancer, anti-fungal, and anti-ulcer, anti-caries, anti-bacterial and wound healing. The preparation of the formulation in accordance with traditional references and evaluation of its analytic and antibacterial properties are the objectives of this study.

Caracterización del tipo de sensibilidad dental de pacientes con periodontitis y su respuesta a los dentífricos / Characterization of the type of dental sensitivity of patients with periodontitis and their response to dentifrices

La hipersensibilidad de la dentina surge ante la exposición de esta y en respuesta a estímulos de diverso tipo, fundamentalmente de origen térmico, evaporativo, táctil, osmótico o químico. Se realizó una investigación abocada a caracterizar la hipersensibilidad dental de pacientes atendidos en consulta de odontología y la respuesta a determinado dentífrico utilizado. En el análisis de estimulación dental se tomaron 308 mediciones de la sensibilidad dental para todos los participantes (n=22), con 7 factores de tiempo (T0 antes del uso del producto, T3 días, T5 días, T8 días, T22 días y T29 días después del uso del dentífrico). Se realizó la prueba paramétrica regresión lineal simple para identificar la tendencia y el ajuste de los datos, al considerar dichas variables como una serie temporal. Se utilizaron 22 tratamientos. Casi el 91,0% expreso que el dentífrico había cumplido sus expectativas, fundamentalmente por la reducción de la hipersensibilidad a corto plazo, mientras que aproximadamente 91,0% de los casos afirmó que compraría el dentífrico (20 casos, IC 95%: 72,2% y 97,5%), respectivamente(AU)

Dentin hypersensitivity arises when exposed to it and in response to various types of stimuli, mainly of thermal, tactile evaporative, osmotic or chemical origin. An investigation was carried out aimed at characterizing the dental hypersensitivity of patients seen in the dental office and the response to a certain toothpaste used. In the dental stimulation analysis, 308 measurements of tooth sensitivity were taken for all participants (n = 22), with 7 time factors (T0 before use of the product, T3 days, T5 days, T8 days, T22 days and T29 days after using the toothpaste). The simple linear regression parametric test was performed to identify the trend and the fit of the data, considering these variables as a time series. 22 treatments were used. Almost 91.0% believed that the toothpaste had met their expectations, mainly due to the reduction in hypersensitivity in the short term, while approximately 91.0% of the cases stated that they would buy the toothpaste (20 cases, 95% CI: 72 , 2% and 97.5%), respectively(AU)

Fluoride concentration in toothpaste marketed to children in Brazil and Mexico, and discussion on current regulations

Resumo Os dentifrícios fluoretados comercializados para crianças devem conter concentração mínima de 1000 ppm de fluoreto (F), que deve ser quimicamente solúvel para ter efeito anticárie. Portanto, determinamos as concentrações de fluoreto total (FT) e fluoreto solúvel total (FST) em dentifrícios comercializados para crianças no Brasil e no México e analisamos as regulamentações vigentes em ambos os países. Vinte e quatro marcas foram encontradas e adquiridas no Brasil (19 formuladas com NaF/SiO2, três com Na2FPO3/CaCO3 e duas com Na2FPO3/SiO2) e seis no México (todas com NaF/SiO2). As concentrações de FT e FST foram determinadas após a compra (amostras frescas), e a estabilidade do fluoreto nas formulações de Na2FPO3/CaCO3 foi verificada após 18 meses. As análises foram realizadas com eletrodo íon-específico e os resultados expressos em ppm F (mg F/kg). As concentrações de FT encontradas variaram de 476,0 a 1.385,3 ppm F e foram próximas às declaradas pelos fabricantes (500 a 1.450 ppm F). As concentrações de FT encontradas não ultrapassaram 1.500 ppm F, de acordo com as regulamentações vigentes de ambos os países. No entanto, dentifrícios com concentrações de FST inferiores a 1.000 ppm F foram encontrados tanto em dentifrício com baixa concentração (500 ppm F) formulado com NaF/SiO2 como em dentifrícios com Na2FPO3/CaCO3 frescos e envelhecidos, originalmente fabricados com 1.000-1.100 ppm de FT. Em conclusão, embora a maioria dos dentifrícios analisados apresentasse concentração de FST superior a 1.000 ppm F, as regulamentações vigentes em ambos os países permitem que produtos que não estejam de acordo com a melhor evidência disponível estejam presentes no mercado.

Abstract Fluoride toothpastes market to children should contain a minimum concentration of 1000 ppm of fluoride (F), which must be chemically soluble to provide anti-caries effect. Therefore, we determined the concentrations of total fluoride (TF) and total soluble fluoride (TSF) in toothpastes marketed to children in Brazil and Mexico and analyzed the current regulations in force in both countries. Twenty-four brands were found and purchased in Brazil (19 formulated with NaF/SiO2, three with Na2FPO3/CaCO3 and two with Na2FPO3/SiO2) and six in Mexico (all with NaF/SiO2). TF and TSF concentrations were determined after the purchase (fresh samples) but fluoride stability in Na2FPO3/CaCO3-formulations was checked after 18 months. The analyses were performed with an ion-specific electrode and the results expressed in ppm F (mg F/kg). The TF concentrations found ranged from 476.0 to 1385.3 ppm F and they were close the declared by the manufactures (500 to 1450 ppm F). The TF concentrations found were not greater than 1500 ppm F, in accordance with the current regulations of both countries. However, toothpastes presenting TSF concentrations lower than 1000 ppm F were found either in low fluoride toothpaste (500 ppm F) formulated with NaF/SiO2 as in fresh and aged Na2FPO3/CaCO3-toothpastes, originally fabricated with 1000-1100 ppm of TF. In conclusion, although most toothpastes analyzed showed TSF concentration higher than 1000 ppm F, the regulations in force in both countries allow that products not in agreement with the best available evidence are available in the market.

Orthodontic therapy produces a greater accumulation of bacterial plaque in patients, with oral ecological changes that cause an increase in the number of mutans streptococci, so it is important to have an adequate oral hygiene that helps to reduce bacteria and prevent caries. Objective. The purpose was to compare the effect of the use of a toothpaste with xylitol on the Streptococcus mutans count in patients with fixed orthodontic appliances. Material and methods. A single-blinded quasi-experimental study was carried out. The sample consisted of 34 adolescent patients with fixed orthodontic appliances of both sexes who met the established criteria. All were instructed in a brushing technique and randomly assigned to one of two groups: 17 patients in the experimental group used a toothpaste with xylitol and 17 patients in the control group used a conventional toothpaste with fluoride. Both groups had bacterial plaque taken and processed microbiologically at the beginning of the study and at 3 and 5 weeks to evaluate the streptococcus mutans count. Results. The T-Student test showed that there were fewer colony-forming units in patients who used xylitol toothpaste with the difference being significant at the fifth week of use (˂ 0.0001). Conclusions. There is greater effectiveness of toothpaste with xylitol in relation to toothpaste with fluoride alone in the Streptococcus mutans count; however, patients in both groups had fewer colony-forming units.

In vitro determination of potentially bioavailable fluoride in diet and toothpaste after ingestion

Aim: To propose a new method to determine in vitro potentially bioavailable fluoride (F) in diet and toothpaste after ingestion. Methods: Diet samples (D) were obtained from 15 portions of a meal served to children in a day care centre. To simulate the ingestion of toothpaste during brushing after meals, a specific amount of toothpaste was added to the diet samples (D + T). F was determined in D and D + T after incubation in a solution that simulated "gastric juice" (0.01 M hydrochloric acid) at 37oC for 30, 60 and 120 min. Microdiffusion facilitated by HMDS was used to determine the total F concentrations in samples D and D + T. The analyses were performed using an ion specific electrode. Results: For D samples, incubation in "gastric juice" for 30, 60 and 120 min resulted in F concentrations (µg F/mL) of 0.75 ± 0.06c, 0.77 ± 0.07c and 0.91 ± 0.09b, corresponding to 75.3, 77.3 and 90.7% of the total F (1.02 ± 0.12a), respectively (p = 0.0001; ANOVA + Tukey). For D + T samples, these values of F concentrations (µg F/mL) were 2.55 ± 0.46b, 2.83 ± 0.44ab and 3.15 ± 0.37a, corresponding to 86.9, 94.8 and 106.7% of the total F (2.99 ± 0.34a), respectively (p = 0.0023; ANOVA + Tukey). Conclusion: Then, it can be concluded that the proposed method of "gastric juice" is a promising protocol for determining potentially bioavailable fluoride in the diet and toothpaste after ingestion. However, additional studies are desirable

Chemically soluble fluoride in toothpastes marketed in Colombia / Fluoruro químicamente soluble en cremas dentales distribuidas en Colombia / Fluoreto químico solúvel em cremos dentários distribuídos na Colômbia

Abstract Introduction and objective: Toothpastes should contain chemically soluble fluoride to have anti-caries efficacy. This study aimed at determining how much of the total fluoride (TF) concentration in the five top-selling children/family Colombian-toothpaste brands corresponds to total chemically soluble fluoride (TSF). Materials and methods: a convenience sample of three tubes of each of the following five toothpaste brands were obtained from three different chain stores, one-per-store, in five Colombian cities (n=3/brand/city): Colgate-Smiles-6+, Kolynos-Super-Blanco, Fortident-Cuatriacción, Colgate-Triple-Acción, Fluocardent. TF (sum of all toothpaste's fluoride) and TSF (toothpaste's chemically soluble fluoride) concentrations were determined in each fresh toothpaste sample (before expiry date) using a standardized ion-specific electrode direct-technique protocol. TF concentration was compared with the manufacturers' declared concentration. The difference between TF and TSF's concentrations purchased in different cities was compared with a one-way ANOVA (5%). Results: Most toothpastes' TF concentration complied with what was declared in the label. One toothpaste had a non-compatible fluoride/abrasive fluoride formulation and TSF < TF; however, it still complied with the minimum TSF requirement to exert a caries-preventive effect (>1000 ppm). Toothpastes' TF and TSF concentrations did not differ between cities (p>0.05). Conclusion: Fresh samples of highly distributed toothpaste brands sold in five Colombian-cities contain chemically available fluoride concentrations with the potential to control and prevent dental caries.

Materiais e métodos: três tubos de cinco marcas diferentes foram coletados em três supermercados da rede; uma por loja, em cinco cidades colombianas (n = 3 / marca / cidade): Colgate-Smiles-6 +, Kolynos-Super-Blanco, Fortident-Quad, Colgate-Triple-Action, Fluocardent. As concentrações de FT e FST foram determinadas em cada uma das amostras frescas, utilizando a técnica direta com eletrodo específico e um protocolo padronizado. A concentração de FT foi comparada com a concentração declarada pelo fabricante. As diferenças entre as concentrações de FT e FST da mesma marca comprada em diferentes cidades foram comparadas com a análise ANOVA (α = 5%). Resultados: a maioria das marcas possui concentrações de flúor que atendem à concentração declarada pelo fabricante. Uma marca contém uma formulação de sal abrasivo e fluoreto quimicamente não compatível e FST menor que FT; no entanto, as amostras frescas atenderam à concentração necessária para exercer um efeito anticárie (> 1000 ppm). As concentrações de FT e TSF não foram significativamente diferentes entre amostras da mesma marca compradas em diferentes cidades (p> 0,05). Conclusão: as amostras frescas (analisadas antes do prazo de validade) das cinco marcas de creme dental com maior distribuição na Colômbia contêm concentrações de fluoreto quimicamente solúvel, com potencial para controlar e prevenir a cárie dentária.

Effect of fluoridated water on dental caries and fluorosis in schoolchildren who use fluoridated dentifrice

Abstract This cross-sectional study evaluated the prevalence and severity of dental caries and fluorosis in children and adolescents using fluoridated toothpaste, from areas with and without fluoridated water. Parents of 5-year-old children and 12-year-old adolescents from neighbourhoods that are supplied with and without fluoridated water answered questionnaires for determining socio-economic and demographic characteristics and habits related to oral health. The individuals were examined, and dental caries and fluorosis were measured by dmft/DMFT and TF indexes, respectively. Descriptive, bivariate and logistic regression analyses were performed (p < 0.05). Of 692 participants, 47.7% were 5-year-olds and 52.3% were 12-year-olds. The mean dmft/DMFT in the 5-year-olds/ 12-year-olds from Exposed and Not Exposed fluoridated water groups was 1.53 (± 2.47) and 3.54 (± 4.10) / 1.53 (± 1.81) and 3.54 (± 3.82), respectively. Children (OR = 2.86, 95% CI = 1.71-4.75) and adolescents (OR = 1.95, 95% CI = 1.24-3.05), who did not consume fluoridated water, had greater caries experience. Among adolescents, there was an association between fluoridated water and the prevalence of very mild/mild fluorosis (OR = 5.45, 95% CI: 3.23-9.19) and moderate fluorosis (OR = 11.11, 95% CI = 4.43-27.87). Children and adolescents, who consumed fluoridated water, presented lower prevalence and severity of dental caries compared to those who used only fluoridated toothpaste as the source of fluoride. There is an association between water fluoridation and very mild/mild and moderate fluorosis in adolescents.

Resumo Este estudo transversal avaliou a prevalência e severidade de cárie dentária e fluorose em crianças de 5 anos e adolescentes de 12 anos usuários de dentifrício fluoretado, em áreas com e sem água fluoretada. Os responsáveis pelas crianças e adolescentes responderam questionários para determinação de características socioeconômicas e demográficas e hábitos relacionados à saúde. Os indivíduos foram examinados e a cárie e a fluorose foram mensuradas pelos índices ceo-d / CPOD e TF, respectivamente. Foram realizadas análises descritivas, bivariadas e de regressão logística (p <0,05). Dos 692 participantes, 47,7% tinham 5 anos e 52,3% tinham 12 anos. A média de ceod / CPOD em crianças de 5/12 anos dos grupos de exposto e não exposto à água fluoretada foi 1,53 (± 2,47) e 3,54 (± 4,10) / 1,53 (± 1,81) e 3,54 (± 3,82), respectivamente. Crianças (OR = 2,86, IC 95% = 1,71-4,75) e adolescentes (OR = 1,95, IC 95% = 1,24-3,05) que não consumiram água fluoretada tiveram maior experiência de cárie. Entre os adolescentes, houve associação entre a água fluoretada e a prevalência de fluorose muito leve / leve (OR = 5,45, IC 95%: 3,23-9,19) e fluorose moderada (OR = 11,11, IC 95% = 4,43-27,87). Crianças e adolescentes que consumiram água fluoretada apresentaram menor prevalência e severidade de cárie dentária em comparação com aqueles que usaram apenas dentifrício fluoretado como fonte de flúor. Houve uma associação entre a fluoretação da água e fluorose muito leve / leve e moderada em adolescentes.

Charcoal-based dentifrices and powders: analyses of product labels, Instagram engagement, and altmetrics

Abstract This study identified charcoal-based dentifrices and abrasive powders sold in Brazil and analyzed their label information. The products were searched in four online shopping platforms. The same products were searched on Instagram and their engagement metrics were investigated. Furthermore, a literature review of international publications assessing charcoal dentifrices and powders was conducted, and altmetrics were collected (Altmetric and PlumX). Thirty-six products were found with prices between $0.4-22 USD. Most frequent words in product description were sodium, stain, whitening, oil, xylitol, and coconut. Only 3 products contained fluoride. Bactericidal, antiviral, antifungal, and anti-inflammatory activities were indicated, in addition to non-scientific claims such as calming teeth or increasing oral immunity. In total, 72% of products had Instagram profiles, which generally showed low engagement rates (81%) and medium audience quality scores (65%). Twenty-two articles were found in the literature, from which 21 were in vitro studies. The single clinical study was sponsored by a charcoal product and had no control group. In total, 23% of studies showed positive results and 55% reported negative results for the charcoal products, which included no whitening ability, increased roughness, surface alterations, and lower demineralization prevention ability. Altmetric scores for the included articles varied from 0 to 55, with 40.9% of studies mentioned online. In conclusion, charcoal-based products are using marketing strategies on Instagram but their current engagement with the public is not high. Consumers are being exposed to charcoal products whose potential risks to health are still unknown.

Foram indicadas atividades bactericidas, antivirais, antifúngicas e anti-inflamatórias, além de alegações não-científicas como acalmar dentes ou aumentar a imunidade oral. No total, 72% dos produtos tinham perfis no Instagram, que geralmente apresentavam baixas taxas de engajamento (81%) e média qualidade de audiência (65%). Vinte e dois artigos foram encontrados na literatura, dos quais 21 foram estudos in vitro. O único estudo clínico foi patrocinado por um produto de carvão e não tinha grupo controle. No total, 23% dos estudos apresentaram resultados positivos e 55% relataram resultados negativos para os produtos de carvão, que incluíram incapacidade de clareamento, aumento da rugosidade, alterações superficiais e menor capacidade de prevenção da desmineralização do esmalte. A altmetria dos artigos incluídos variou de 0 a 55, com 40,9% dos estudos sendo mencionados online. Em conclusão, os produtos à base de carvão estão usando estratégias de marketing no Instagram, mas seu engajamento atual com o público não é alto. Consumidores estão sendo expostos a produtos de carvão cujos potenciais riscos à saúde ainda são desconhecidos

Fluoride and Functionalised β-tricalcium Phosphate (fTCP) Fluoride Toothpaste Affect the Primary Dentin Caries Surface: A Comparison by Estimation Statistics

ABSTRACT@#This study aims to compare the effect of fTCP-contained toothpaste in combination with 950 ppm fluoride on primary dentin caries surface to ordinary 1100 ppm fluoride toothpaste by using estimation statistics. Dental caries with deep lesion and dentin exposure from nine primary teeth were cut into two equal parts and randomly divided into two groups in a before-after study. Each group was brushed with one type of toothpaste two times per day for 28 days and rested in artificial saliva. SEM images of cavity bottom surfaces and energy-dispersive X-ray spectrometry (EDX) were used to determine the percentage of calcium (Ca), phosphorus (P), fluoride (F) and oxygen (O) at six continuous measured areas from the surface of the cavity bottom into 45 µm depth before and after brushing. About 95% confidence interval of the mean difference was calculated by performing bootstrap resampling with 5000 resamples followed by comparison analysis. The percentage of Ca, P, F, O was shifted after treatment. There was no difference between the two groups. The SEM images reflected a similar illustration of EDX data. The combination of fTCP and 950 ppm fluoride in toothpaste showed equivalent effectiveness to the 1100 ppm fluoride toothpaste in primary dentin caries.

Efeito de dentifrício com alta concentração de flúor na remineralização e resistência de união de cimento de ionômero de vidro em substratos dentários com cárie artificial / Effect of dentifrice with high concentration of fluoride under remineralization and bond strength of glass ionomer cement on dental substrates with artificial caries

O objetivo do presente estudo foi avaliar a influência de diferentes dentifrícios na dureza de superfície, em secção transversal e perfil de desgaste do esmalte, assim como na resistência de união de cimentos de ionômero de vidro de alta viscosidade (CIV-AV) à dentina, após indução de cárie artificial, ciclagem de pH e escovação. Foram utilizados 80 dentes bovinos, divididos em blocos de esmalte e dentina. Os espécimes de esmalte foram polidos e selecionados de acordo com a microdureza. Em seguida, metade de cada bloco de esmalte foi protegida com verniz ácido resistente. Os espécimes de dentina foram incluídos em resina acrílica e planificados. O protocolo de cárie artificial foi feito através de ciclos de desmineralização em esmalte (n=20) e pela imersão da dentina (n=40) em solução desmineralizadora. Vinte amostras de dentina não foram submetidas à cárie, sendo o grupo controle. Todas as amostras foram submetidas à ciclagem de pH e escovação durante 7 dias de acordo com cada dentifrício: Colgate Total 12 1450 ppm F (CT) e Clinpro 5000 ppm F + TCP (CL). Em seguida, os blocos de esmalte foram submetidos às análises de dureza de superfície, em secção transversal e perfilometria. Microscopia eletrônica de varredura foi realizada em três blocos representativos de cada grupo. Os espécimes de dentina foram subdivididos de acordo com material restaurador: CIV-AV Ketac Molar (KM) e cimento ionomérico híbrido Equia Forte (EF). Em seguida, as amostras foram armazenadas sob umidade relativa durante 24 horas e preparados para o teste de microcisalhamento. Os dados obtidos foram submetidos ao teste de normalidade, análise de variância (ANOVA) 1 critério para avaliar a recuperação mineral e perfil de desgaste, ANOVA 2 critérios com medidas repetidas para avaliar a dureza de superfície e em secção transversal, ANOVA 3 critérios para avaliar o microcisalhamento e pós teste de Tukey para comparações múltiplas, com significância de 5%. Observou-se recuperação parcial da dureza de superfície, independente do dentifrício. Os dados da dureza em secção transversal evidenciaram que CL obteve valores inferiores a CT até 90 micrômetros (m) no lado teste. O dentifrício CT apresentou maior desgaste quando comparado à CL. Em dentina, ao comparar os dentifrícios dentro de cada CIV, CT apresentou maior resistência adesiva para ambos os materiais. A comparação entre CIVs dentro do mesmo dentifrício evidenciou resistência adesiva superior para KM quando comparado à EF na dentina tratada com CL. Conclui-se que o dentifrício com maior concentração de flúor promoveu menor dureza em secção transversal no esmalte e o dentifrício convencional resultou em maior desgaste superficial. Na superfície dentinária, o dentifrício com maior concentração de flúor diminuiu a resistência adesiva de cimentos de ionômero de vidro(AU)

The aim of the present study was to evaluate the influence of different dentifrices on surface hardness and cross-sectional hardness, wear profile on enamel, as well as on the bond strength of high viscosity glass ionomer cements (HV-GIC) to dentin, after to produce artificial caries, pH cycling and brushing. Eighty bovine teeth were used, divided into enamel and dentin blocks. The enamel specimens were polished and selected according to microhardness. Then, half of each enamel block was covered with resistant acid varnish. Dentin specimens were embedded in acrylic resin and flattened. The artificial caries protocol was carried out through enamel demineralization cycles (n= 20), and the dentin (n= 40) was immersed in demineralizing solution. Twenty dentin specimens were not subjected to artificial caries, being the control group. All blocks were subjected to pH cycling and brushing for 7 days according to each dentifrice: Colgate Total 12 1450 ppm F (CT) and Clinpro 5000 ppm F + TCP (CL). Then, the protected enamel surfaces were exposed for the analysis of surface hardness, cross sectional hardness and profilometry. Scanning electron microscopy was performed in three representative blocks of each group. The dentin specimens were subdivided according to restorative material: HVGIC Ketac Molar (KM), and hybrid GIC Equia Forte (EF). Then, the specimens were stored under relative humidity for 24 hours and prepared for the micro-shear test. The data were submitted to normality test, one-way analysis of variance (ANOVA) to assess mineral recovery and wear, two-way repeated measures ANOVA to assess surface and cross-sectional hardness, and three-way ANOVA to analyze the bond strength. Tukey post-test was used for multiple comparisons, with a significance level of 5%. It was observed a partial recovery of superficial microhardness, regardless of the dentifrice. Cross sectional hardness data showed that CL obtained values below CT up to 90 micrometers (m) on the test side. CT dentifrice presented greater wear when compared to CL. In dentin, when the dentifrices were compared within each GIC, CT showed greater adhesive resistance for both materials. A comparison between GICs within the same dentifrice showed superior adhesive resistance for KM when compared to EF in dentin treated with CL. It was concluded that the dentifrice with the highest fluoride concentration promoted less cross-sectional hardness in the enamel and the conventional dentifrice resulted in greater surface wear. On the dentin, the dentifrice with the highest fluoride concentration decreased the adhesive strength of glass ionomer cements(AU)

Protection of calcium silicate/sodium phosphate/fluoride toothpaste with serum on enamel and dentin erosive wear

Abstract Objective To evaluate the effect of a toothpaste containing calcium silicate/sodium phosphate/fluoride associated or not to the boost serum (BS) against erosive tooth wear (ETW) on enamel and dentin. Methodology Bovine enamel and dentin specimens were subjected to an erosion-abrasion cycling model (1% citric acid - pH 3.6 -2 min / artificial saliva - 60 min, 4×/day, 5 days). Toothbrushing was performed for 15 s (2 min exposed to slurry), 2×/day, with the toothpastes (n=10): control without fluoride (Weleda), Arg/Ca/MFP (Colgate Pro-Relief), Si/PO4/MFP (Regenerate-Unilever), and Si/PO4/MFP/BS (Si/PO4/MFP with dual BS - Advanced Enamel Serum-Unilever). The effect of treatments on the eroded tissues was assessed by surface microhardness in the first day, and surface loss (SL) resulting from ETW was evaluated by profilometry (μm) after three and five days. Additional dentin specimens (n=5/group) were subjected to 20,000 brushing cycles to verify the abrasivity of the toothpastes. Data were subjected to ANOVA and correlation tests (5%). Results For enamel, no difference in microhardness was observed among the treated groups, and similar SL was obtained after 5 days. For dentin, Si/PO4/MFP/BS resulted in higher microhardness values, but none of the groups presented significantly lower SL than the control. There was no significant correlation between SL and abrasiveness. Conclusion The calcium silicate/sodium phosphate toothpaste and serum increased microhardness of eroded dentin, but they did not significantly reduce enamel and dentin loss compared to the non-fluoride control toothpaste. The abrasiveness of the toothpastes could not predict their effect on ETW.

Remineralizing Effect of Xilitol, Juniperus Communis and Camellia Sinensis Added to a Toothpaste: An In Vitro Study / Efecto remineralizante del Xilitol, Juniperus Communis y Camellia Sinensis adicionados en pastas dentales: Estudio in vitro

ABSTRACT The aim of this study was to explore the remineralizing effect of toothpastes based on Xilitol, Camellia Sinensis and Juniperus Communis. An in vitro experimental study was carried out in an 18 human premolars sample, which were treated with one of the 3 evaluated toothpastes and a control fluoride one. The atomic percentages of Ca and P were evaluated by Energy Dispersive X-ray Spectroscopy (EDS). In addition, the enamel surface of treated teeth was visualized by Scanning Electron Microscopy (SEM). The evaluations were carried out in three stages: pre-treatment, after an artificial demineralization process and after the treatment with the toothpastes. In the statistical analysis, the one-way ANOVA and Pearson correlation tests were used. Xilitol and Juniperus Communis showed the greatest gain of P ions compared to the control group (p<0.01). As for Ca, the group treated with xylitol-based toothpaste showed more ion gain compared with the control group (p<0.01). In the Pearson correlation test between Ca and P, statistically significant correlations were observed in all groups (p<0.01), ranging between r=0.7413 (Xylitol Group) and r=0.9510 (Control Group). We concluded that Xylitol paste showed the highest remineralizing property, both in the EDS analysis and in the SEM images.
