RESUMO

Purpose: To assess the effects of a soft drink, a soybean-based apple juice and strawberry juice on the superficial and deep microhardness of primary tooth enamel.
Methods: Sixty primary teeth were divided according to the beverages and a control group (artificial saliva). Immersion cycles were carried out under agitation (five minutes three times a day over 60 days). Superficial microhardness measurements were taken after seven, 15, 30, 45, and 60 days. Teeth were cut for deep microhardness evaluation. Analysis of variance and Tukey's test (95 percent confidence interval) were used for data analysis. Teeth were scanned by electron microscopy for quantitative analysis.
Results: The soybean drink led to a significant decrease in the superficial microhardness ( P <0.05) at all tested times. The decrease for the strawberry juice was steeper than for the soybean drink and the soft drink significantly decreased the superficial microhardness at all times. The soybean drink recorded lower surface deep microhardness values while the juice presented similar results to the soybean drink at a depth of up to 200 µm. There was a gradual and statistically significant increase at a depth of up to 300 µm with the soft drink. Scanning electron microscopy evaluation showed that all beverages had gradual demineralization, being evident on the 60th day; the soft drink showed the greatest overall loss of enamel.
Conclusion: All beverages affected the microhardness of primary teeth enamel. The soft drink was the most harmful to enamel among the assessed beverages.

RESUMO

BACKGROUND: This in-vitro-study aimed to evaluate the potential of different fluoride gels to prevent gastroesophageal reflux induced erosive tooth wear. METHODS: Surface baseline profiles of a total of 50 bovine enamel specimens [randomly assigned to five groups (G1-5)] were recorded. All specimens were positioned in a custom made artificial oral cavity and perfused with artificial saliva (0.5 ml/min). Reflux was simulated 11 times a day during 12 h by adding HCl (pH 3.0) for 30 s (flow rate 2 ml/min). During the remaining 12 h (overnight), specimens were stored in artificial saliva and brushed twice a day (morning and evening) with a toothbrush and toothpaste slurry (15 brushing strokes). While specimens in the control group (G1) did not receive any further treatment, specimens in G2-5 were coated with different fluoride gels [Elmex Gelée (G2); Paro Amin Fluor Gelée (G3); Paro Fluor Gelée Natriumfluorid (G4); Sensodyne ProSchmelz Fluorid Gelée (G5)] in the evening for 30 s. After 20 days, surface profiles were recorded again and enamel loss was determined by comparing them with the baseline profiles. The results were statistically analysed using one-way analysis of variance (ANOVA) followed by Tukey`s HSD post-hoc test. RESULTS: The overall highest mean wear of enamel (9.88 ± 1.73 µm) was observed in the control group (G1), where no fluoride gel was applied. It was significantly higher (p < 0.001) compared to all other groups. G2 (5.03 ± 1.43 µm), G3 (5.47 ± 0.63 µm, p = 0.918) and G4 (5.14 ± 0.82 µm, p > 0.999) showed the overall best protection from hydrochloric acid induced erosion. Enamel wear in G5 (6.64 ± 0.86 µm) was significantly higher compared to G2 (p = 0.028) and G4 (p = 0.047). CONCLUSIONS: After 20 days of daily application, all investigated fluoride gels are able to significantly reduce gastroesophageal reflux induced loss of enamel.

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

We evaluated the quality of general dental practitioner (GDP) tooth wear (TW) referrals to secondary care services in Kent, Surrey and Sussex.Prospective consecutive referrals received via an electronic pathway were assessed from 1 June to 30 October 2019. Reasons for referral, patient demographics, quality of referral, opinion of the triaging clinician and outcome were assessed.Of 671 referrals, 32% were for TW. Males were referred more commonly (1.7:1.0). The median age was 52. Patients were more likely to be referred from distant locations than places closer to the referral centre (p<0.001). Only 55% of referrals suggested a cause for the TW, 33% provided a clinical photograph and 1% recorded a tooth wear index of any type. Referring clinicians most commonly cited attrition as reason for referral (p<0.001). Those under 40 years were referred for erosion (p=0.001) and those over 40 years, attrition (p=0.019). The triaging clinician was more likely to allocate a tooth wear score of three for those under 40 years and a score of four for over 40 years (p<0.001). 47% of referrals were rejected. Males and referrals with photographs were more likely to be accepted for treatment (p=0.017 and p<0.001, respectively).There is a high demand for specialist TW services. The number of referrals being rejected has not changed using the electronic referral system. We advocate the inclusion of mandatory fields for completion by GDPs as well as compulsory clinical photographs and tooth wear indices (Smith and Knight Tooth Wear Index or a basic erosive wear examination - BEWE index).

RESUMO

This study evaluated how Er,Cr:YSGG laser, associated or not with 5% fluoride varnish, influences the surface roughness and volume loss of bovine root dentin submitted to erosive and/or abrasive wear. One hundred and twenty dentin specimens were divided into the groups: without preventive treatment (WPT), 5% fluoride varnish (FV); Er,Cr:YSGG laser irradiation (L), and varnish combined with laser (FV + L). The specimens (n = 10) were subdivided into: 1 = erosion (E); 2 = abrasion (A); and 3 = erosion followed by abrasion (E + A). The erosive solution used was a soft-drink (pH = 2.42 at 4ºC) applied in 5-min cycles twice a day for 10d. Abrasive wear involved brushing for 60s with an electric brush (1,600-oscillations/s) at a load of 2.0N. Surface roughness and volume loss were evaluated using a laser scanning confocal microscope. Roughness data were submitted to one-way ANOVA and Tukey post-hoc test. For volume loss, the Kruskal-Wallis and Dunn's post-hoc tests were used (α = 5%). The lowest values of roughness were found in the control areas of all subgroups (p > 0.05). In the experimental area, the [(WPT) + (E+A)] subgroup had a significantly higher roughness (5.712 ± 0.163 µm 2 ) than the other subgroups (p < 0.05). The L and (FV + L) groups had statistically similar roughness, regardless of the type of wear. The (FV + L) group had the lowest volume loss, regardless of the type of wear performed: [(FV + L) + (E)] = 7.5%, [(FV + L) + (A) = 7.3%, and [(FV + L) + (E + A)] = 8.1%. The subgroup [(WPT) + (E + A)] had the highest volume loss (52.3%). The proposed treatments were effective in controlling dentin roughness. Laser irradiation can be an effective method to increase root dentin resistance after challenges and limit problems related to non-carious lesions.

RESUMO

OBJECTIVE: To investigate the measurement threshold of an intra-oral scanner (IOS) on polished human enamel. METHODS: The optical performance of an IOS was compared to a gold-standard non contacting laser profilometer (NCLP), on a painted microscope slide, compared to increasing particle size of silicon-carbide papers (21.8-269.0 µm) and separately on polished human enamel with increasing step-heights. The enamel samples were randomised (n = 80) and scanned using the IOS and NCLP at increasing step-height depths (µm) (1.87-86.46 µm) and quantified according to ISO:5436-1. The measurement threshold of the IOS was determined using a custom designed automated lesion localisation algorithm, corroborated by Gaussian skewness (Ssk) and kurtosis (Sku) analysis, to assess the minimum step-height measured on each enamel sample. RESULTS: The NCLP showed statistically increased Sq surface roughness for all silicon carbide particle sizes compared to the microscope slide, whereas, the IOS Sq roughness discriminated silicon-carbide particles above 68.0 µm compared to the glass slide (p ≤ 0.02). On polished enamel, the automated minimum detectable step-height measurable on each sample was 44 µm. No statistically significantly different step-height enamel lesion measurements were observed between NCLP and IOS above this threshold (p > 0.05). SIGNIFICANCE: This study revealed the fundamental optical metrological parameters for the IOS, was step-heights above 44 µm and this reflects the data acquisition of the system. These results highlight the limitations of IOS used in this study, mandating further research to optimise the performance of other IOS systems, for measuring wear of materials or tooth wear on human unpolished natural enamel surfaces.

RESUMO

OBJECTIVE: This study investigated the mechanism of action of different proteins/peptides (separately or in combination), focusing on how they act directly on the native enamel surface and on modifying the salivary pellicle. METHODS: A total of 170 native human enamel specimens were prepared and submitted to different treatments (2 h; 37 °C): with deionized water, CaneCPI-5, Hemoglobin, Statherin, or a combination of all three proteins/peptides. The groups were subdivided into treatment acting on the enamel surface (NoP - absence of salivary pellicle), and treatment modifying the salivary pellicle (P). Treatment was made (2 h; 37 °C) in all specimens, and later, for P, the specimens were incubated in human saliva (2 h; 37 °C). In both cases, the specimens were immersed in 1% citric acid (pH 3.6; 2 min; 25 °C). Calcium released from enamel (CaR) and its relative surface reflection intensity (%SRI) was measured after 5 cycles. Between-group differences were verified with two-way ANOVA, with "presence of pellicle" and "treatment" as factors (α = 0.05). RESULTS: The presence of pellicle provided better protection regarding %SRI (p < 0.01), but not regarding CaR (p = 0.201). In relation to treatment, when compared to the control group, all proteins/peptides provided significantly better protection (p < 0.01 for %SRI and Car). The combination of all three proteins/peptides demonstrated the best protective effect (p < 0.01 for %SRI). CONCLUSION: Depending on the protein or peptide, its erosion-inhibiting effect derives from their interaction with the enamel surface or from modifying the pellicle, so a combination of proteins and peptides provides the best protection. CLINICAL SIGNIFICANCE: The present study opens a new direction for a possible treatment with a combination of proteins for native human enamel, which can act directly on the enamel surface as well on the modification of the salivary pellicle, for the prevention of dental erosion.

RESUMO

Diversas medidas vêm sendo propostas para a prevenção e controle do desgaste erosivo, como o uso de produtos fluoretados e lasers de alta potência. Este estudo in situ, cego e cruzado, visou avaliar o efeito do laser de CO2 (9.3 ?m), associado ou não a solução de AmF/NaF/SnCl2, na prevenção (Etapa 1: prevenção da lesão, amostras inicialmente hígidas) e controle (Etapa 2: controle da progressão da lesão, amostras previamente erodidas) da erosão dental em esmalte dental humano. As etapas foram divididas em duas fases, uma sem a exposição à solução de AmF/NaF/SnCl2 (Fase I) e outra com (Fase II). Para tanto, 192 fragmentos de esmalte dental humano (3 x 3 x 1 mm) foram divididos, randomicamente, em 4 grupos experimentais em cada etapa (n=12): C - sem tratamento (controle negativo); F - solução de AmF/NaF/SnCl2 (controle positivo); L - irradiação com laser de CO2 (9.3 ? ); L + - laser de CO2 (9.3 ? ) + solução de AmF/NaF/SnCl2. Doze voluntários utilizaram um dispositivo removível inferior bilateral contendo 8 amostras/fase. As amostras foram submetidas ao desafio erosivo ex vivo por meio de sua imersão em ácido cítrico (1,0%; pH 2,3; 5 minutos; 4x/dia em intervalos diferentes para cada fase, durante 5 dias). A perda de superfície foi determinada através da perfilometria óptica (n=12), e a morfologioa de superfície foi observada em Microscopia Eletrônica de Varredura (MEV). Para MEV, foram selecionadas 24 amostras (n=3) submetidas aos 5 dias de ciclagem e, adicionalmente, 24 amostras extras (n=3), submetidas aos tratamentos de superfície. Os dados das amostras da Etapa 1 foram analisados estatisticamente através de ANOVA 1-fator, e as da Etapa 2, através de ANOVA 2-fatores para medidas repetidas (Tempo - lesão inicial e após 5 dias; e Tratamento - C, F, L, L + F); ambos com posterior comparação múltipla através do teste de Tukey. Na análise da Etapa 1, observou-se que os grupos L (4,59 ± 2,95 ? )e L + F (1 58 ± 1 24 ? ) apresentaram melhores resultados na prevenção de lesão de erosão, diferindo estatisticamente dos grupos C e F, os quais não diferiram entre si. E na etapa 2, o grupo L + F (4,99 ± 1,17 ? ) apresentou melhores resultados no controle da progressão da lesão, sendo o único grupo a não apresentar perda de superfície significativa entre lesão inicial e após 5 dias de ciclagem quando comparado com a lesão inicial. Portanto, o laser de CO2 apresentou potencial em prevenir e controlar a progressão de erosão em esmalte dental humano, apresentando maior eficácia quando associado à solução de AmF/NaF/SnCl2.

RESUMO

OBJECTIVE: This article is aimed at providing an overview of the topic of erosive tooth wear (ETW), highlighting the clinical signs, diagnosis, and management of dental erosion. OVERVIEW: With the increased prevalence of ETW, it is important that oral health professionals are able to recognize the early signs. Early clinical signs of dental erosion are characterized by loss of enamel texture, a silky glossy appearance, and sometimes a dulling of the surface gloss, referred to as the "whipped clay effect, cupping, and restorations 'standing proud'." The progression of ETW should be monitored by means of diagnostic models or clinical photographs. ETW can be as a result of acid attack of extrinsic or intrinsic origin. CONCLUSION: There is an increase of ETW that is being recognized by the profession. The first step in diagnosing and management is to recognize as early as possible that the process is occurring. At that point a determination of whether the primary etiology is either intrinsic or extrinsic should be made. If these findings are confirmed, appropriate prevention, and management strategies can be adopted followed by appropriate restorative therapy. CLINICAL SIGNIFICANCE: The prevalence of ETW continues to increase. It is therefore important that oral health care providers have a better understanding of the etiology, pathophysiology, and management of this condition. This review aims to provide the guidelines for diagnosis and management of dental erosion.

RESUMO

OBJECTIVE: To investigate the modification of the salivary pellicle with different polyphenol-rich teas and natural extracts for the protection against dental erosion. METHODS: We performed two experiments: one with teas (Green tea, Black tea, Peppermint tea, Rosehip tea, negative control [NC]) and other with natural extracts (Grape seed, Grapefruit seed, Cranberry, Propolis, NC), where NC was deionized water. A total of 150 enamel specimens were used (n = 15/group). Both experiments followed the same design, consisting of 5 cycles of: salivary pellicle formation (30 min, 37 °C), modification with the solutions (30 min, 25 °C), further salivary pellicle formation (60 min, 37 °C) and erosive challenge (1 min, 1% citric acid, pH 3.6). Relative surface microhardness (rSMH), relative surface reflection intensity (rSRI) and amount of calcium release (CaR) were evaluated. Data were analysed with Kruskal-Wallis and Wilcoxon rank sum tests with Bonferroni correction (α = 0.05). RESULTS: Regarding teas, Black and Green teas showed the best protection against dental erosion, presenting higher rSMH and lower CaR than NC. Peppermint tea was not different to NC and Rosehip tea caused erosion, showing the highest CaR and greatest loss of SMH and SRI. Regarding natural extracts, Grape seed and Grapefruit seed extracts presented the best protective effect, with significantly higher rSMH and lower CaR. Cranberry caused significantly more demineralization; and Propolis did not differ from NC. CONCLUSION: Green tea, Black tea, Grape seed extract and Grapefruit seed extract were able to modify the salivary pellicle and improve its protective effect against enamel erosion, but Rosehip tea and Cranberry extract caused erosion. CLINICAL RELEVANCE: Some some bio-products, such as teas and natural extracts, improve the protective effect of the salivary pellicle against enamel erosion. More studies should be performed in order to test the viability of their use as active ingredients for oral care products.

RESUMO

PURPOSE: A previous clinical study showed that the prevalence of erosive toothwear in vegetarians is statistically significantly higher than in nonvegetarians, due to the consumption of vinegar and other acidic foodstuffs. To adequately inform patients, this study investigated the erosive potential of bottled salad dressings available in Switzerland and compared it with that of orange juice. Materials and Methods: One hundred enamel samples of bovine teeth were divided into ten groups. Samples were placed in 1 of 9 bottled salad dressings or orange juice (Granini) for 2 min. Afterwards, they were rinsed with Zürich tap water for 30 s, followed by abrasion with a toothbrush for 20 brush strokes and a toothpaste-saliva mixture. Erosive/abrasive enamel wear was determined with contact profilometry after 40 cycles. Results: The enamel wear (median/IQR) caused by Tradition Sauce Balsamique (9.5 µm/5.3 µm), M-Classic Dressing Italiano (10.9 µm/12.3 µm), Betty Bossi Balsamico Dressing (9.4 µm/4.5 µm) and Thomy Balsamico Vinaigrette Dressing (14.2 µm/6.5 µm) was statistically significantly higher than that caused by orange juice (2.4 µm/0.8 µm). Enamel wear caused by M-Classic Dressing French Joghurt (0.2 µm/0.2 µm) and Coop Qualité & Prix French Dressing (1.2 µm/1.0 µm) was statistically significantly lower compared to that of orange juice. Conclusions: The pure balsamico vinegar-based dressings (Italian type) showed a statistically significantly higher erosive potential than orange juice, whereas dressings containing calcium-rich products (enriched with milk and/or cream) (French-type) caused lower enamel wear than orange juice. The study shows that some bottled dressings have erosive potential even higher than orange juice and patients should be informed accordingly.

RESUMO

Objective: This study examined the impact of early biofilm on the tooth surface, during the assessment of initial enamel erosion using swept-source optical coherence tomography (SS-OCT). Method and materials: Forty-five enamel windows of 2 × 4 mm2 were prepared on 23 extracted human teeth. The specimens were exposed to citric acid (pH 3.2) for 30 minutes and randomly divided into three groups (n = 15): Group 1, no biofilm; Group 2, 1-day-old biofilm; and Group 3, 3-day-old biofilm. Specimens in Groups 2 and 3 were inoculated with oral bacteria (Streptococcus sanguinis, Streptococcus mitis, and Actinomyces naeslundii) to produce early laboratory-cultivated biofilms for 1 and 3 days respectively. Surface microhardness (SMH) measurements were taken at pre- (t1) and post-erosion (t2); and SS-OCT scans were done at t1, t2, and post-biofilm cultivation (t3). Integrated reflectivity (IR) of the tooth-air interface (IRsurface) and enamel (IRenamel) were computed from the mean A-scans. Statistical analysis was performed using paired t tests and one-way ANOVA (α = .05). Results: A significant increase in IRenamel was observed at t2 (P < .05). At t3, IRsurface between Group 1 (control) and Group 2 (P = .012) as well as Group 3 (P = .001) were significantly different. Significant variances in IRenamel were perceived between t2 and t3 for Groups 2 and 3 but not for Group 1. Conclusion: As early biofilm affected SS-OCT assessment of initial enamel erosion, they should be removed from the tooth surface prior to OCT procedures..

RESUMO

OBJECTIVES: To assess the erosive potential of dry mouth lozenges and tablets on enamel and dentin. MATERIALS AND METHODS: The following lozenges and tablets were tested: Salese, Oracoat Xylimelts, Cotton Mouth, TheraBreath, DenTek OraMoist, SmartMouth, ACT, CVS Health, Rite Aid, Med Active, and Hager Pharma. pH Analysis: Each lozenge or tablet was crushed with a pestle and mortar and 5 g of the resultant powder was dissolved in 10 ml of distilled water (pH 7.02) The pH of each lozenge solution was assessed by using a calibrated pH meter. Titratable Acidity (TA) was determined by adding 0.1 M of NaOH to each homogenous tablet solution until the pH reached 7.0. Gravimetric Analysis was measured with freshly extracted molars crown/roots were sectioned at the CEJ and enamel and dentin specimens were fabricated. The specimens were then submerged in 5 ml of solution containing 2.5 gm of crushed tablets for 24 h, 48 h, 96 h and 14 days with measurements performed at each interval after drying. The solutions were renewed at each interval. RESULTS: Significant correlation between pH and TA was observed for lozenges and tablets evaluated (p < 0.0001). Both variables were strongly correlated with enamel and dentin loss (p < 0.0001). For enamel, DenTek resulted in significantly more substance loss (p < 0.05) than with the other tested products, while Xylimelts presented the lowest percentage of substance loss. For dentin, Cotton Mouth resulted in the highest substance loss, and Xylimelts presented the lowest percentage of substance loss. CONCLUSIONS: There is a strong correlation between the pH, tritatable aciditiy, and erosive potential of these products. DenTek and Cotton Mouth reported erosive effect to the enamel and dentin, respectively. Xylimelts performed better than the rest of the products in relationship to enamel and dentin.

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

This study investigated the potential of red wine in modulating dental erosion kinetics in the presence or absence of salivary pellicle. Polished human enamel specimens were used in two conditions; presence or absence of acquired enamel pellicle; and subdivided according to exposure: red wine, orange juice, apple juice, or citric acid. The specimens were incubated in clarified whole human saliva (presence of acquired enamel pellicle) or in a humid chamber (absence of acquired enamel pellicle) for 2 h at 37°C, then in the test substances for 1 min, at 25°C, under shaking. This was repeated four times. Surface hardness was measured initially and after each cycle and surface reflection intensity was measured initially and after all cycles. In the presence of acquired enamel pellicle, red wine caused the least surface hardness loss, followed by orange juice, apple juice, and citric acid. Statistically significantly less surface reflection intensity loss was observed for red wine and orange juice than for apple juice and citric acid. In the absence of acquired enamel pellicle, red wine and orange juice caused less surface hardness loss than apple juice and citric acid. Orange juice showed the least surface reflection intensity loss, followed by red wine, citric acid, and apple juice. The polyphenol composition of these drinks can notably modulate the erosion kinetics.

RESUMO

This study aimed to evaluate the erosive potential of powdered juice drinks on dental enamel in 2 stages: physiochemical characterization and erosive challenge testing. In stage 1, the pH and titratable acidity of 5 commercially available powdered juices in 10 different flavors were analyzed. Five treatment groups were then established based on the pH values, titratable acidity, and presence of citric acid in the juices, and their energy-dispersive X-ray (EDX) spectroscopy profiles were studied. In stage 2, the erosive effect of the juices was tested using a pH cycling model; polished bovine dental enamel blocks (n = 8) were treated 4 times daily on 5 consecutive days with 1% citric acid (positive control) or lemon, orange, pineapple, or cashew juice. The specimens were immersed in the erosive solutions, under agitation (100 rpm), for 1 minute at 25°C. Overnight and between treatments, the blocks were stored in artificial saliva without agitation. At the end of cycling, the enamel surfaces were evaluated by profilometry and scanning electron microscopy. The stage 2 results were submitted to 1-way analysis of variance followed by Tukey test (α = 0.05). The pH values of the juices ranged between 2.86 (lemon) and 3.84 (cashew), while the titratable acidity ranged from 14.5 (cashew) to 90.00 (lemon) mmol/L. Lemon juice showed the least calcium content (2.76%) and no (0.00%) phosphorus concentration. Orange, pineapple, and cashew juices showed the greatest concentrations of calcium and phosphorus and were therefore less erosive than lemon juice. The mean [SD] surface loss was higher in the lemon juice group (0.52 [0.16] µm), with no significant differences (P > 0.05) from the control (0.39 [0.09] µm) and orange juice (0.41 [0.12] µm). In groups exposed to pineapple juice (0.36 [0.04] µm) and cashew juice (0.16 [0.08] µm), the surface loss was significantly lower (P < 0.05) than that found in lemon juice. The results demonstrate that powdered juice drinks (especially lemon juice) present erosive potential and lead to surface loss of dental enamel.

RESUMO

OBJECTIVES: To compare the prevalence of parafunctional habits, erosive tooth wear and occurrence of tooth injuries among children being under the care of Social Welfare Centre and children treated in the Department of Children's Dentistry of the Medical University of Warsaw. STUDY DESIGN: The study contains environmental and medical interviews, record-based analysis and clinical examination. Parafunctional habits were rated on the base of dental interviews and clinical examinations. The occlusal surfaces were evaluated by visual examination using modified tooth wear index (TWI). Tooth injuries were reported from a medical interview labeled using Andreasen classification. The consent of the bioethics committee and guardians of children participated in the study was obtained. RESULTS: The study involved 782 patients, including 404 children from dysfunctional families (average age 11,4 ± 3,7) and 378 from ordinary families-control group (8,53 ± 3,92). In the study group we observed higher prevalence of erosive tooth wear (44,66% vs 18,02% p=0,000), dental trauma (9,4% vs 3,44% p=0,001) and a presence of parafunctional habits (67,8% vs 20,4 % p=0,000). CONCLUSION: The occurrence of parafunctional habits, erosive tooth wear and tooth injuries may be an indicator of domestic violence and a component of maltreated child syndrome.

RESUMO

PURPOSE: This study aimed to estimate the prevalence, distribution, and the associated factors of tooth erosion in Turkish school children. MATERIALS AND METHODS: A cross-sectional analysis was performed on a representative sample of 473 children (aged 7-14 years) from 11 public schools in Turkey. Parents were asked to fill out a questionnaire to collect sociodemographic data. A questionnaire was also given to the children, to collect data pertaining to personal demographic details and habits of consuming acidic foods and drinks. The O'Sullivan index was used to assess affected permanent teeth. The data were analysed using a chi-square test and multivariate logistic regression analysis. RESULTS: Dental erosion was observed in 21.8% of the children. Lesions were most often observed in the enamel with less than half of the buccal surface affected. Erosion was found to be statistically significantly higher in older children and in those with an elevated body mass index (BMI) (p <0.05). The consumption of fruit juices, drinks with cola, orange soft drinks, gaseous, cocoa milk, iced tea, sodas, sports drinks, energy drinks, oranges, lemons, kiwis, grapefruits, apples, peaches, and fruit yogurts was statistically significantly higher in students with erosion (p <0.05). There was no statistically significant relationship between students' sex, systemic disease, premature birth and low birth weight, exercise activity level, socioeconomic status, parental education level, and oral hygiene habits with erosion (p >0.05). CONCLUSION: Although erosive lesions were limited to the enamel, the prevalence of erosion was high. Erosion was statistically significantly associated with older age, elevated BMI, consumption of certain beverages, and fruit.

RESUMO

Evaluated the effect of CPP-ACP/NaF and xylitol/NaF varnishes in reduce erosion and progression of erosion. Forty enamel blocks were divided into four groups (n=10): G1=CPP-ACP/NaF varnish (MI varnishTM); G2=xylitol/NaF varnish (Profluorid®); G3=NaF varnish (Duraphat®, positive control) and G4=deionized water (MilliQ®, negative control). Samples were immersed in Sprite ZeroTM (pH 2.58, 4x/day, 3 days), in between immersions, the specimens stayed in artificial saliva. After 3 days of erosion, the eroded area was divided in two (half of one received an additional varnish layer while the other half repeated the same 3-day erosion cycle). The 3D, non-contact profilometry technique was used to determinate tooth structure loss (TSL) and surface roughness (SR). Scanning electron microscopy (SEM) and 3D images were utilized to evaluate the topography of the samples. Mann-Whitney, one-way ANOVA and Tukey tests were used (significance level of 0.05%). SEM and 3D images were descriptively evaluated. After 3 or 6 days of erosion, all tested varnishes were better than G4 (p<0.05) for TSL and SR. In addition, G1 had lower values for TSL than G3 (p<0.05) after 3 days of erosion. Under SEM and 3D images observation, all groups presented porosity, irregularities and depressions on the surface enamel after 3 and 6 days of erosion, more pronounced in G4. An application of topical NaF varnishes was effective in reducing TSL and enamel roughness after erosion challenges, being the CCP-ACP/NaF varnish more effective than NaF varnish and water after 3 days of erosion.

RESUMO

INTRODUCCIÓN: la erosión dental es la pérdida patológica, crónica, localizada e indolora de los tejidos dentarios, producida por la acción química de ácidos y sin la intervención de la acción de microorganismos. En los últimos años se ha observado un incremento significativo de la prevalencia de esta patología, especialmente en niños y adolescentes. OBJETIVOS: determinar la prevalencia de la erosión dental en la dentición temporal mediante el índice Basic Erosive Wear Examination (BEWE) en niños de entre 5 y 12 años, y determinar los hábitos de alimentación que pueden favorecer en ellos el desarrollo de lesiones. MÉTODOS: se llevó a cabo un estudio transversal en una muestra de 391 niños. Se realizó una encuesta donde se analizaron los hábitos de alimentación, y se realizó una exploración clínica de los dientes temporales empleando el índice BEWE. RESULTADOS: la prevalencia de la erosión dental en la muestra estudiada fue del 19,7 %, presentándose con mayor frecuencia lesiones iniciales. CONCLUSIONES: el 30,62 % de la población estudiada presentaba riesgo bajo de erosión dental, observándose un aumento del riesgo a medida que aumentaba el consumo de bebidas ácidas (bebidas gaseosas, bebidas isotónicas y zumos de frutas) y frutas ácidas, como naranjas, uvas y manzanas


INTRODUCTION: dental erosion is the pathological, chronic, localized and painless loss of dental tissues, produced by the chemical action of acids, where the action of microorganisms is not involved. In recent years, a significant increase in the prevalence of this pathology has been observed, especially in children and adolescents. OBJECTIVES: to determine the prevalence of dental erosion in temporary dentition using the Basic Erosive Wear Examination Index (BEWE) in children between 5 and 12 years of age, and to determine the eating habits that may favor the development of these lesions. METHODS: a cross-sectional study was carried out on a sample of 391 children. A survey was conducted where eating habits were analyzed and a clinical examination of the temporary teeth was performed using the BEWE index. RESULTS: the prevalence of dental erosion in the studied sample was 19.7 %, with mild lesions being most common. CONCLUSIONS: in all, 30.62 % of the studied population had a low risk of dental erosion, and risk was seen to increase with consumption of acidic beverages (soft drinks, isotonic drinks and fruit juices) and acidic fruits such as oranges, grapes and apples
