RESUMO

PURPOSE: To compare the effects of whitening toothpaste and bleaching with 6% hydrogen peroxide (H2O2) on discoloration of dental resin composite caused by cigarette smoke (CS) and electronic vapor product (EVP) aerosol. METHODS: 40 resin composite discs were divided into three groups: 15 each for CS and EVP aerosol exposure and 10 for air exposure (control). Exposures were performed for 15 days, with daily brushing with regular toothpaste. Two whitening sessions, including 21 days of brushing with whitening toothpaste and 3 days of treatments with take-home bleaching (6% H2O2), were performed after the exposure. Color and gloss were assessed before exposure, at every 5 days of exposure, and after each whitening session. RESULTS: After 15 days of exposure, marked discoloration of resin composite was observed in the CS group (ΔE = 23.66 ± 2.31), minimal color change in the EVP group ((ΔE = 2.77 ± 0.75), and no color change in the control group. Resin composites exposed to CS did not recover their original color after treatment with whitening toothpaste ((ΔE = 20.17 ± 2.68) or take-home bleaching ((ΔE = 19.32 ± 2.53), but those exposed to EVP aerosol reverted to baseline after treatment with whitening toothpaste ((ΔE = 0.98 ± 0.37), and no further change in color was observed following take-home bleaching. The gloss of resin composites exposed to CS, EVP aerosol, and air decreased equally with exposure time. Brushing with whitening toothpaste recovered the gloss similarly in all groups, but no further change was observed following take-home bleaching. CLINICAL SIGNIFICANCE: Aerosol from electronic vapor products induced minimal discoloration of resin composites that can be completely reverted by brushing with whitening toothpaste alone. Bleaching with 6% H2O2 did not revert discoloration caused by cigarette smoke. Whitening toothpaste could help revert the decreased gloss of resin composites.

RESUMO

THE AIM OF THE STUDY: Was to evaluate the clinical efficacy of parodontax Comprehensive Protection (GlaxoSmithKline, London, UK) toothpaste in the complex therapy of chronic gingivitis. MATERIALS AND METHODS: The study involved 119 volunteers; group 1 (n=59, age range 18 to 32 years) and group 2 (n=60, age range 20 to 35 years) with a diagnosis of chronic gingivitis (K05.1). The criterion for inclusion in the study was sulcus bleeding index (SBI) more than 1 point. Dental examination included SBI, papillary-marginal-alveolar index (PMA), and Green-Vermillion oral hygiene index (OHI-S). After determining the indices, all patients underwent professional oral hygiene and controlled tooth cleaning. Patients in group 1 (parodontax) were prescribed parodontax Comprehensive Protection toothpaste (GlaxoSmithKline, London, UK), patients in group 2 - a toothpaste that did not contain sodium bicarbonate. Repeated clinical examinations with the determination of the SBI, PMA, OHI-S were carried out after week 2 and 4. RESULTS: After 4 weeks, SBI scores in group 1 were 63% lower than at baseline, and in group 2 - by 30%. PMA values at 4 weeks in group 1 were 58% and in group 2 30% lower, compared to baseline levels. The results of the analysis of the OHI-S index showed a statistically significant decrease in group 1 by 75%, while in group 2 by only 8% from the initial values. The difference in all index values between groups at 4 weeks of the study was statistically significant (p<0.05). CONCLUSION: The use of parodontax Comprehensive Protection Toothpaste (GlaxoSmithKline, London, UK) has been shown to reduce the clinical signs of biofilm-associated gingivitis and effectively maintain optimal oral hygiene in patients.

RESUMO

PURPOSE: To investigate the effect of slurry abrasive levels and acidic challenges on the development of non-carious cervical lesions. METHODS: Ninety-six extracted upper premolars were affixed in pairs to acrylic blocks and had their root surfaces covered by acrylic resin except for 2 mm from the cemento-enamel junction. The specimens were distributed into six groups (n = 8 pairs) based on two experimental factors: (1) slurry abrasivity level [low/medium/high] and (2) citric acid challenge [yes/no]. Specimens were brushed for 5,000, 15,000, 35,000, and 65,000 strokes. Volume loss (VL) was determined based on optical profilometry scans of specimens impressions at the baseline and at subsequent brushing levels. Data were analyzed using repeated measures analysis of variance and Bonferroni pairwise comparison (α = 0.05). RESULTS: Higher VL values were associated with high-abrasivity slurries relative to low- and medium-abrasivity slurries (P < 0.001). Increasing the slurry abrasivity level increased the VL regardless of the acidic challenge, which did not have a significant effect (P = 0.184). After 65,000 strokes, significant VL was recorded in all groups relative to preceding brushing levels (P < 0.001). CONCLUSION: Higher values of time-dependent surface loss were associated with increased dentifrice slurry abrasivity, regardless of the citric acid challenge.

RESUMO

OBJECTIVE: To assess the effects for controlling extrinsic tooth stain of a whitening toothpaste containing 10% high cleaning silica, 0.5% sodium phytate and 0.5% sodium pyrophosphate, in comparison with a negative control toothpaste. METHODS: A total of 86 adults who met with the inclusion and exclusion criteria were invited to take part in the study. They were distributed into test and control groups randomly. At baseline, 4 weeks and 8 weeks, the same examiner provided the clinical examinations, including evaluations of oral soft and hard tissues and measurements of tooth stain of the anterior teeth using the Lobene Stain Index. Adverse events and any changes in general health conditions of the patients were monitored. RESULTS: When the study was completed, comparisons between patients in test and control groups yielded statistically significant differences in Lobene stain adjusted mean area score [0.83 (0.05) vs. 1.13 (0.05)], Lobene stain adjusted mean intensity score [0.99 (0.06) vs. 1.32 (0.06)] and Lobene stain adjusted mean composite score [1.45 (0.13) vs. 2.50 (0.13)] (All, P < 0.001). Patients in the test group exhibited reductions of 26.55%, 25% and 42%, respectively in Lobene stain area, intensity and composite scores, relative to patients in the control group. Comparisons within groups showed that all three Lobene scores at 8 weeks in both groups were lower than those at baseline (All, P < 0.001). CONCLUSION: This study demonstrates that 8-week use of a toothpaste containing 10% high cleaning silica, 0.5% sodium phytate and 0.5% sodium pyrophosphate can effectively reduce extrinsic tooth stain. Trial registration NCT04238429 (before enrollment of the first participant). Data register: March 4, 2018.

RESUMO

The COVID-19 pandemic has drawn attention to microbial transmission risk via aerosols in dental practice. Demonstration electric toothbrushes are used intra-orally for education. The aim of this investigation was to measure the size of droplets emitted by the brush head of two demonstration oscillating-rotating electric toothbrushes. Measurement of droplet production and size was recorded in vitro using three methods: (1) Malvern Spraytec (LASER particle size measurement device with detectable particle size of 0.1-2500 µm) and brushes mounted on a 3D-printed, two-shell form-fit fixture with a supply of tap water; (2) a DustTrak aerosol measurement device and toothpaste slurry, with brushing simulated in the oral cavity of a phantom head; (3) high-speed visualization in a simulated-use situation in the oral cavity of a phantom head, with individual evaluation of tap water, water with detergent, 70% ethanol, glycerin and toothpaste slurry. Both brushes showed the size of emitted droplets was consistently between 200 and 1200 µm, categorized as splatter (dental aerosols are <50 µm diameter). No significant incremental aerosol-sized matter was detected during toothbrush operation. The high-speed video visualization confirmed only splatter-sized droplets during operation. These findings indicate that oscillating-rotating toothbrushes do not produce aerosol-sized particles during simulated use.

RESUMO

PURPOSE: A novel anhydrous toothpaste formulation has been developed containing the anti-dentinal hypersensitivity (DH) ingredient stannous fluoride (SnF2). MATERIALS AND METHODS: This randomised, controlled, examiner-blind, parallel-group, stratified (by baseline Schiff sensitivity score) study compared efficacy of an experimental 'Test' toothpaste (n = 67) containing 0.454% SnF2, 0.072% sodium fluoride and 5% sodium tripolyphosphate (all percentages w/w) with a negative 'Control' 0.76% sodium monofluorophosphate toothpaste (n = 68) in relieving DH in healthy Chinese adults. After 4-6 weeks acclimatisation, DH was assessed at baseline and following 4 and 8 weeks' twice-daily brushing by response to evaporative (air) (Schiff sensitivity score) and tactile (Yeaple probe) stimuli. An analysis of covariance model was used (factor: treatment group; covariate: baseline Schiff sensitivity score). RESULTS: Both Test and Control toothpastes statistically significantly reduced Schiff sensitivity score from baseline after 8 weeks' use; the Test toothpaste also statistically significantly reduced the score after 4 weeks' use (all p < 0.001). The Test toothpaste reduction was statistically significantly superior to the Control toothpaste reduction at both timepoints (p < 0.001). Percentage differences in treatment effects between Test and Control groups were 24.1% at 4 weeks and 31.7% at 8 weeks. Tactile threshold scores for both treatments statistically significantly increased from baseline at both timepoints (all p < 0.001); however, there were no statistically significant differences between Test and Control groups. Both toothpastes were well-tolerated with no adverse events reported. CONCLUSION: The Test toothpaste containing 0.454% SnF2 reduced DH statistically significantly more than the Control as evaluated by the Schiff sensitivity score, but not by tactile threshold.

RESUMO

Oral hygiene is an important step in the control of the biofilm, a factor related to diseases such as gingivitis and tooth decay. The systematization of oral hygiene in children is a set of measures that seeks to achieve sequential learning, thus guaranteeing a better elimination of the biofilm. Objetive: To show a sequence of systematized steps in oral hygiene in a pediatric patient with a definitely positive behavior. Case Report: Six year old female patient, without relevant medical history. On clinical intraoral examination presented biofilm accumulation and swollen gums. The presumptive diagnosis was marginal gingivitis associated with biofilm, the treatment included a preventive phase with motivation and education. The control of the disease evolution was carried out with a card of Systematization Technique of Oral Hygiene, the methodology included the recording of the educational sessions using videos and photographs. Results: the adequate use of the amount of toothpaste was achieved, the integrity was improved to 100%, the brushing time increased from 24 to 120 seconds and it was possible to add tongue brushing and not rinsing after brushing within the oral hygiene routine. Conclusion: The patient was able to clean all dental surfaces, using homogeneous times for each surface, following an orderly sequence in toothbrushing, as well as to acquire knowledge regarding the amount of toothpaste to use, tongue brushing and not rinsing after toothbrushing. The systematization of oral hygiene allowed us to achieve these achievements in six sessions.

RESUMO

This in vitro study evaluated the biocompatibility and abrasivity of whitening and conventional toothpastes. Samples of conventional (non-whitening) - Edel White Infant (EWI) - and whitening toothpastes - Edel White Whitening (EWW), Edel White CAREFORTE (EWC), Colgate Total 12 Ò Professional (C), and Oral-B Whitening (OB) - were dissolved in culture medium (0.2 g sample weight per mL). Human gingival fibroblasts (hGF) were placed in contact with different dilutions of culture media that had been previously exposed to these toothpastes. Cytotoxicity was then assessed using the methyl tetrazolium test (MTT) and the cell survival rate was determined. Genotoxicity was assessed by the micronucleus test (MNT) and the number of micronuclei was determined before and after exposure to the toothpaste solutions. The enamel surface roughness was evaluated in specimens of bovine teeth (n = 10 per group) before and after 10,000 brushing cycles, using the investigated toothpastes. The results were statistically analyzed using the Mann-Whitney U test and two-way ANOVA (p < 0.05). According to the MTT assay, EWW and OB presented significant cytotoxicity (p < 0.01), but no genotoxic (MNT) effects (p > 0.05). C toothpaste was statistically significantly abrasive to the enamel surface (p < 0.01). The findings of this study may be helpful for individualized selection of commercial toothpastes, as some whitening toothpastes present significant cytotoxicity and conventional toothpaste cause significant surface changes.

RESUMO

OBJECTIVES: This randomised, controlled, analyst blind, crossover study aimed to evaluate and compare salivary fluoride and calcium ion concentration over 60 min following brushing with an assigned treatment and following an orange juice (OJ) or deionised (DI) water rinse 60 min post-brushing. METHODS: Study treatments, both containing 1150 ppm fluoride as NaF and 5% w/w KNO3, were the Test (including 1.2 % w/w cocamidopropyl betaine) and Comparator (including tetrasodium pyrophosphate and sodium lauryl sulphate) toothpastes. Twenty nine participants were randomised to treatment. RESULTS: A sharp increase in salivary fluoride ion concentration immediately post-brushing with either toothpaste decreased over time. Fluoride concentration following Test toothpaste use was numerically higher than the Comparator at all timepoints, with a significant difference from 10 min post-brushing (p < .05). Following the 60 min rinse, there were no significant differences between the Test or Comparator + OJ groups in salivary fluoride concentration but the Test + DI water group was significantly lower than Test (p < .001) or Comparator (p < .001) + OJ groups. A reduction in salivary calcium ion concentration was seen immediately post-brushing and after the OJ rinse with both toothpastes. Significant differences were observed in favour of the Test toothpaste at all timepoints (p < .05) and for Test and Comparator + OJ group (p < .001) compared with Test + DI water rinse. Both treatments were generally well-tolerated. CONCLUSIONS: This study demonstrated that toothpaste formulations with identical declared fluoride concentrations and the same fluoride source give rise to differing intraoral fluoride concentrations over time, which are potentially related to different formulation excipient effects. CLINICAL SIGNIFICANCE: By understanding the interaction of toothpaste formulation excipients in the oral environment, formulations can be developed that maximise retention of fluoride in the oral environment.

RESUMO

Objective: This study aimed to examine and compare the anti-caries effects of slightly acidic 1% NaF-HF gel when applied once or twice (7-day or 6-month interval) to mandibular first molars in 6- to 7-year-old children. Method and materials: This was a 1-year, multi-arm, placebo-controlled, double-blind, parallel-group randomized trial. In total, 1,077 schoolchildren from eight primary schools were allocated to one of the four study groups (group 1, single application; group 2, two applications with a 7-day interval; group 3, two applications with a 6-month interval; group 4, placebo control). The occlusal surfaces of permanent mandibular first molars were examined by three calibrated examiners who were blind to the group allocation at baseline and the end of the study. Caries reduction and prevented fraction was assessed. Results: A total of 986 children completed the study. There was a statistically significant difference in the mean D1MFT increment across the groups (P < .001). The mean D1MFT increment was 0.37 in group 1 (single application), 0.18 in group 2 (two applications with a 7-day interval), 0.21 in group 3 (two applications with a 6-month interval), and 0.56 in the control group. The mean D2MFT increments (0.22 in group 1, 0.06 in group 2, 0.18 in group 3, and 0.50 in the control group) also showed a statistically significant difference across the groups (P < .001). Conclusion: Subacidic 1% NaF-HF gel exerts a high preventive effect on caries (more than 40%) when applied twice at a 7-day interval in 6- to 7-year-old schoolchildren who do not use fluoride toothpaste in areas where drinking water is not fluoridated.

RESUMO

The formation of a physiological biofilm cannot be avoided under normal circumstances. However, the consequences of a supragingivally located biofilm, such as caries, gingivitis and, as a further effect, periodontitis, are relatively easy to avoid. The simplest and most common method used worldwide for the elimination of biofilm is periodic mechanical removal using a toothbrush or similar tools, such as chewing sticks or woods. This method was already used in ancient Egypt, and is still being used today, albeit advanced and improved with the help of toothpastes. Here we give a summary of the most common toothbrushes, highlighting their advantages and disadvantages. Furthermore, we provide an overview of the most common toothpastes, their ingredients, and functions. In addition, the ingredients will be critically evaluated and recommendations given for the use or non-use of certain ingredients for different target groups, such as children, healthy adults, or patients with special needs.

RESUMO

Three-dimensional, organotypic models of the oral mucosa have been developed to study a wide variety of phenomena occurring in the oral cavity. Although a number of models have been developed in academic research labs, only a few models have been commercialized. Models from academic groups offer a broader range of phenotypes while the commercial models are more focused on the oral and gingival mucosa. The commercialized models are manufactured under highly controlled conditions and meet the requirements of quality standards, which leads to high levels of reproducibility. These in vitro models have been used to evaluate the irritancy of oral care products such as toothpastes, mouthwashes, and mucoadhesives. The effects of cigarette smoke on oral cavity tissues have been studied and compared to those of e-cigarettes. Oral tissue models have facilitated investigation of the mechanisms of oral mucositis and oral candidiasis and have been used to examine transbuccal drug delivery rates and the absorption of nanoparticles. Infection studies have investigated the effects of HIV-1 along with the effects of commensal and pathogenic bacteria. More recently, a differentiated oral tissue model has been shown to express the ACE2 receptor, which is known to be important for the receptor-mediated entry of the SARS-CoV-2 coronavirus into human cells and tissues. Hence, oral mucosal models may find application in determining whether viral infection of the oral mucosa is possible and whether such infection has implications vis-a-vis the current COVID-19 pandemic. As is apparent, these models are used in a broad variety of applications and often offer advantages versus animal models in terms of reproducibility, avoiding species extrapolation, and the ethical concerns related to human and animal experimentation. The goals of this paper are to review commercially available models of the human buccal and gingival mucosa and highlight their use to gain a better understanding of a broad range of phenomena affecting tissues in the oral cavity.

RESUMO

Enzymes in toothpastes can support host immune responses, and thus maintain oral health. This study aimed to investigate gingival health and the plaque-reducing effects of enzyme-containing toothpastes. A laboratory study tested the antimicrobial potential of different enzyme-containing toothpaste formulations. Two promising formulations (enzyme-containing toothpastes with glucose oxidase and D-glucose with (C+) and without Citrox (C-) Citrox) were investigated in a clinical crossover trial (two slurries: sodium lauryl sulfate-containing (SLS), a toothpaste without SLS (reference), and water). Subjects (n = 20) abstained from toothbrushing for four days and rinsed with a toothpaste slurry. Bleeding on probing (BOP) and plaque indices (PI) were measured. A mixed linear model was used to statistically compare the slurries with respect to BOP and PI change. The in vitro bacterial growth-inhibiting evaluation showed the best results for SLS, followed by C+ and C-. The change in BOP and PI exhibited statistically significant differences to water rinsing (BOP; PI changes in % points (difference of the baseline and post-rinse values: water = 8.8%; 90.0%; C+ = -1.4%; 80.4%; SLS = 1.5%; 72.1%; reference = 0.8%; 77.5%; C- = -1.8%; 75.1%). All slurries exhibited anti-gingivitis and anti-plaque effects, resulting in a prophylactic benefit for limited-access regions during brushing.

RESUMO

OBJECTIVE: To evaluate whether a blue covarine containing silica-based toothpaste promotes a whitening effect immediately after tooth brushing. METHODS: A triple-blind, parallel group, randomized design was used to compare the tooth color before and after brushing. Two silica-based toothpastes were chosen, one of them containing blue covarine (BCT) and the other one without pigment to serve as control (CT). Tooth color was measured using a spectrophotometer and expressed as CIEDE 2000 ΔE, CIELAB values, WIO index, WID index and VITA scale tooth shade. In addition, the participants' satisfaction with and perception of their own tooth color were registered using an aesthetic numeric analogue scale. RESULTS: No significant changes in color components or dimensions measured using CIEDE 2000 ΔE (CT: mean = 1.3, 95% CI 0.8, 1.7; BCT: mean = 1.6, 95% CI 1.2, 2.1), WIO, WID, VITA scale or CIELAB values were detected for the CT and BCT groups, comparing the results before and after brushing. Likewise, the participants' satisfaction with the treatment results (P = 0.31) and the participants' evaluation of tooth color (P = 0.71) did not differ significantly between groups. CONCLUSION: After a single application, no significant improvement in tooth whiteness by the presence of blue covarine in a silica-based toothpaste was detected in color dimensions or by assessing the participants' satisfaction and perception. CLINICAL SIGNIFICANCE: The present study does not show a clinically relevant increase in tooth whiteness after a single brushing with a blue covarine containing toothpaste, nor could the study participants observe a difference between treatment with blue covarine containing toothpaste and control treatment.

RESUMO

OBJECTIVES: To compare the effect of bioavailable gluconate-chelated stannous fluoride (SnF2) toothpaste with control toothpastes for treatment of dentine hypersensitivity (DH) and enamel erosion. DATA AND SOURCES: A Procter & Gamble Oral Care archive of clinical studies was reviewed from 2000 to 2020. Eligible studies were Randomised Controlled Trials (RCTs) investigating bioavailable gluconate-chelated SnF2 toothpaste efficacy compared to controls in adult participants measured following tactile (Yeaple force) and/or evaporative stimuli (Schiff score) in-vivo, duration <2 months (DH); or by erosive toothwear (profilometry) from in-situ samples, duration 10-15 days. Two authors independently assessed eligibility and resolved disagreements by discussion. A meta-analysis was undertaken and Risk of Bias (RoB) assessed using the Cochrane collaboration RoB tool for randomized parallel-group and cross-over trials. RESULTS: Fourteen RCTs (1287 participants) assessed DH relief and Six RCTs (184 participants) enamel erosion protection. For DH SnF2 toothpastes provided a 57 % (evaporative air) and 142 % (tactile) benefit versus negative controls (sodium fluoride/monofluorophosphate, 8 studies; p < 0.001). Compared to positive controls (potassium nitrate or arginine, 6 studies), a 22 % advantage (p = 0.036) was seen for evaporative air. In erosion studies, SnF2 toothpastes provided an 83 % benefit versus control toothpastes (arginine or sodium fluoride; p < 0.001) with a change (95 %CI) in average surface profilometry level (µm) of -2.02(-2.85, -1.20). CONCLUSIONS: The use of these bioavailable SnF2 toothpastes, as part of a daily oral hygiene regimen, will provide patients with enamel erosion protection, combined with alleviation of DH pain when present, improving quality of life.

RESUMO

Objetive: Manufacturers of toothpastes claim that their products are active against oral microbiome capable of causing tooth decay. The objective of this study was to investigate the manufacturers' claim using some of the toothpaste products sold in Ado-Ekiti, Nigeria. Material and methods: The antibacterial potentials of five commercialized toothpaste products (designated sodium fluoride-zinc sulphate, benzyl alcohol-sodium fluorophosphate, sodium fluoride-eugenol, sodium fluoride-sodium laurylsulfate and sodium fluoride-potassium nitrate) were tested against six oral isolates of dental caries and periodontal origin ­ Staphylococcus aureus, Streptococcus mitis, Streptococcus salivarius, Streptococcus pyogenes and Pseudomonas aeruginosa. The antimicrobial potentials were evaluated using modified agar well diffusion method. Various dilutions of the toothpaste products from 1:1 to 1:16 were tested against each test microorganism. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the toothpastes were determined. Results: sodium fluoride-zinc sulphate, benzyl alcohol-sodium fluorophosphate and sodium fluoride-eugenol toothpastes showed inhibitory effects on S. aureus, S. mitis and S. salivarius. Sodium fluoride-sodium laurylsulfate and sodium fluoride-potassium nitrate toothpastes showed no inhibitory effect on the organisms except S. pyogenes. Only sodium fluoride-potassium nitrate toothpaste inhibited E. coli while none of the toothpastes inhibited P. aeruginosa. The MIC and MBC of sodium fluoride-zinc sulphate, benzyl alcohol-sodium fluorophosphate, and sodium fluoride-eugenol toothpastes showed bacteriostatic and bactericidal effects on the organisms. Sodium fluoride-zinc sulphate, benzyl alcohol-sodium fluorophosphate, and sodium fluoride-eugenol toothpastes showed comparable effects on S. aureus, S. mitis and S. salivarius. Sodium fluoride-eugenol toothpaste was strongest against S. mitis, benzyl alcohol-sodium fluorophosphates toothpaste was strongest against S. pyogenes, sodium fluoride-zinc sulphate toothpaste was strongest against S. salivarius and only sodium fluoride-potassium nitrate toothpaste inhibited E. coli. Conclusion: The manufacturer's claim is upheld by this study for sodium fluoride-zinc sulphate, benzyl alcohol-sodium fluorophosphate and sodium fluoride-eugenol toothpastes. However, sodium fluoride-sodium laurylsulfate and sodium fluoride-potassium nitrate toothpastes showed limited inhibitory potentials (AU)


Objetivo: Os fabricantes de dentifrícios afirmam que seus produtos são ativos contra a microbiota oral capaz de causar cáries. O objetivo deste estudo foi investigar a justificativa dos fabricantes sobre o uso de alguns produtos na pasta de dente vendida em Ado-Ekiti, Nigeria. Materiais e métodos:Os potenciais agentes antibacterianos dos cinco produtos de creme dental comercializados (denominados fluoreto de sódio-sulfato de zinco, álcool benzilico-fluorofosfato de sódio, fluoreto de sódio-eugenol, fluoreto de sódio-laurilsulfato de sódio-nitrato de potássio) foram testados contra 06 isolados orais de cárie dentária e origem periodontal - Staphylococcus aureus, Streptococcus mitis, Streptococcus salivarius, Streptococcus piogenes e Pseudomonas aeruginosa. Os potenciais antimicrobianos foram avaliados usando o método de difusão em ágar modificado. Várias diluições dos produtos das pastas de dente de 1:1 a 1:16 foram testadas contra cada microorganismo citado. A concentração inibitório mínima (MIC) e a concentração bactericida mínima (CBM) das pastas de dente foram determinadas. Resultados: As pastas de fluoreto de sódio-sulfato de zinco, álcool benzilico-fluorofosfato de sódio e fluoreto de sódio-eugenol apresentaram efeitos inibitórios sobre S. aureus, S. mitis, S. salivarius. Os dentifrícios com fluoreto de sódio-laurilsulfato de sódio e fluoreto de sódio-nitrato de potássio não mostraram efeito inibitório sobre os microorganismos, exceto S. pyogenes. Apenas o creme dental com fluoreto de sódio e nitrato de potássio inibiu a E. coli, enquanto nenhum dos dentifrícios inibiu a P. aeruginosa. O MIC e CBM de fluoreto de sóido-sulfato de zinco, álcool benzilico-fluorofosfato de sódio e dentifrício fluoreto de sódio-eugenol mostraram efeitos bacteriostáticos e bactericidas sobre os organismos. As pastas de fluoreto de sódio-sulfato de zinco, álcool benzilico-fluorofosfato de sódio-eugenol mostraram efeitos comparáveis em S. aureus, S. mitis e S. salivarius. O creme dental com fluoreto de sódio-eugenol foi o mais forte contra S. mitis, o creme dental com álcool benzilico e fluorofosfatos de sódio foi o mais forte contra S. pyogenes, o creme dental com fluoreto de sódio-sulfato de zinco foi o mais forte contra o S. salivarius e apenas o creme dental com fluoreto de sódio-nitrato de potássio inibiu E. coli.Conclusão: A utilização de alguns produtos pelo fabricante é confirmada por este estudo para as pastas de dente com fluoreto de sódio-zinco, álcool benzilico-fluorofosfato de sódio e fluoreto de sódio-eugenol. No entanto, os dentifrícios com fluoreto de sódio-laurilsulfato de sódio e fluoreto de sódio-nitrato de potássio apresentaram potencial inibitório limitado (AU).

RESUMO

OBJECTIVE: To evaluate the effects of combination of treatments with fluoridated toothpastes supplemented with sodium trimetaphosphate (TMP) and casein phosphopeptide-amorphous calcium phosphate (MI Paste Plus®), on the remineralization of dental enamel. DESIGN: Enamel blocks with artificial caries were randomly allocated into six groups (n = 12), according to the toothpastes: 1) without F-TMP-MI Paste Plus® (Placebo); 2) 1100 ppm F (1100 F), 3) MI Paste Plus®, 4) 1100 F + MI Paste Plus® (1100 F-MI Paste Plus®), 5) 1100 F + 3% TMP (1100 F-TMP) and 6) 1100 F-TMP + MI Paste Plus® (1100 F-TMP-MI Paste Plus®). Blocks were treated 2×/day with slurries of toothpastes (1 min). Furthermore, groups 4 and 6 received the application of MI Paste Plus® for 3 min. After pH cycling, the percentage of surface hardness recovery (%SHR); integrated loss of subsurface hardness (ΔKHN); profile analysis and lesion depth subsurface through polarized light microscopy (PLM), confocal laser scanning microscopy (LSCM), scanning electron microscopy (SEM), fluoride (F), calcium (Ca), phosphorus (P) concentrations in the enamel were determined. The data were analyzed by ANOVA (1-criterion) and Student-Newman-Keuls test (p < 0.001). RESULTS: 1100 F-TMP-MI Paste Plus® group showed the best results of %SHR, ΔKHN and PLM (p < 0.001). F concentration was similar between the 1100 F, 1100 F-MI Paste Plus®, and 1100 F-TMP-MI Paste Plus® groups (p > 0.001). 1100 F-TMP-MI Paste Plus® group showed the highest concentration of Ca and P in the enamel (p < 0.001). CONCLUSION: The association of 1100 F-TMP and MI Paste Plus® led to a significant increase in the remineralization of initial carious lesions.
