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

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

Lesões cervicais não cariosas [LCNC] são a perda de tecido dental, esmalte e/ou dentina, próximo da junção amelocementária [JAC], sem a presença de agentes bacterianos cariogênicos. Os dentes pré-molares superiores são os mais frequentemente acometidos. Mais de 90% das lesões estão localizadas na face vestibular dos dentes. Têm etiologia multifatorial, mas o mecanismo de ação dos fatores etiológicos e da interação entre eles ainda não foi claramente elucidada. Apesar da abrasão e a erosão ácida serem os agentes etiológicos mais considerados por muitos anos, eles não são capazes de explicar a ocorrência de lesões subgengivais, nem as que acontecem em um dente isoladamente dos vizinhos. O fator mecânico, que pode atuar isoladamente em um dente, passou a ser investigado como potencial responsável pelas lesões, sozinho ou atuando sinergicamente com a erosão ácida. Uma das possibilidades de interação entre os fatores etiológicos seria o mecanismo conhecido como "stress corrosion crack". Mas existiria uma outra possibilidade: esmalte e dentina podem ser considerados materiais poroelásticos, que apresentam uma fase sólida porosa e uma fase com fluido, livre para se deslocar entre os espaços deixados pela fase sólida. Isto faria que os tecidos dentários funcionassem como esponjas, cada um com sua rigidez específica. Ou seja, poderiam ser capazes de absorver fluido circundante se, ao serem deformados, aumentasse seu volume total. Pelo contrário, expeliriam fluido interno se a deformação ocorresse com diminuição de volume. Estas possibilidades, ao ocorrer com alternância, poderiam gerar o intercâmbio forçado de líquido com o meio externo, além de sua circulação interna forçada, decorrentes das tensões cíclicas a que os dentes estão habitualmente expostos. Se esse líquido fosse ácido, poderia causar desmineralização e perda de substância, o que justificaria a formação das LCNC "desenhadas" especificamente em regiões em que concentra a tensão (ou a deformação). Para avaliar se é válida esta proposta de mecanismo etiológico, foi realizada a presente pesquisa, 100% in silico, dividida em duas partes: 1) estudo do comportamento microestrutural do esmalte e da dentina [micro]; 2) estudo de um dente como macroestrutura poroelástica [macro]. Na parte micro, modelos lineares elásticos 2D representaram a microestrutura, repetida periodicamente, do esmalte e da dentina, visando verificar se a relação entre tensão (de tração ou de compressão) e variação de volume de cada componente microestrutural dos tecidos e o volume seria linear. Assim seria possível verificar se se poderia esperar, ou não, efeitos semelhantes sob carregamentos compressivos ou de tração. Foi avaliado todo o espectro possível de cargas, até a fratura, visando verificar também se haveria alguma não linearidade na relação, que poderia ser devida às características de estruturação dos tecidos, que propiciassem colapso estrutural acima de algum valor de tensão. Na parte macro foi desenvolvido um modelo 2D de primeiro pré-molar superior com características poroelásticas, submetido a três direções de carregamento em relação ao longo eixo: oblíquo (cúspide vestibular); longitudinal cêntrico (no sulco); longitudinal excêntrico (próximo da cúspide vestibular), visando verificar: 1) se existe não linearidade entre magnitude de tensão e volume de fluido "bombeado" (expelido ou absorvido) pelos tecidos; 2) se tanto a tração quanto a compressão têm a mesma capacidade de bombeamento de fluido; 3) se a distribuição do fluido na região cervical, durante o carregamento, seria capaz de desenhar os formatos das lesões, arredondadas ou anguladas. Os resultados das simulações por elementos finitos mostraram que: 1) a relação entre a variação volumétrica de cada uma das fases microestruturais e a tensão média nos modelos é linear, tanto para a dentina quanto para o esmalte. Isto sugere que não exista um valor de tensão abaixo do qual dentina ou esmalte ficariam isentos de LCNC (pois tensões menores ainda poderiam apresentar efeito danoso, caso estivessem presentes com maior frequência), nem haveria um limiar de tensão partir do qual aumentasse a taxa de bombeamento, de modo a exacerbar o mecanismo de formação da LCNC; 2) a taxa de variação volumétrica é igual tanto sob tração como compressão. Isto seria compatível, pelo modelo proposto, com a formação das LCNCs por carregamentos que conduzam tanto à compressão como à tração localizadas, como se verifica na clínica; 3) é possível que a dentina intertubular, apesar de não representar um caminho tão desimpedido quanto os túbulos, seja capaz de bombear os maiores totais de volume de líquido e, por isso, seria a mais envolvida no processo do bombeamento e dissolução. Isto é compatível com o fato de que na superfície de LCNCs ativas sejam encontrados túbulos obliterados e não exista sensibilidade dentinária em muitos casos. A peritubular é a que apresenta menor capacidade de forçar a circulação de fluidos. 4) No esmalte, a região interprismática, como um todo, apresenta uma maior capacidade de bombear fluidos que a região prismática. 5) A relação entre magnitude de tensão e volume bombeado na região cervical pela dentina e pelo esmalte foi linear no estudo macro. Isto significa que não haveria uma tensão limiar a partir da qual a probabilidade de formação de LCNC aumentasse. 6) Tanto a tração quanto a compressão, foram capazes de gerarem bombeamento e, consequentemente provocariam LCNCs, As forças oblíquas para vestibular tendem a gerar tensão de compressão e fluxo com o dobro de volume na face vestibular que na palatina, o que é compatível coma maior incidência de LCNC na vestibular, encontrada clinicamente; 7) O maior volume encontrado no tecido dentinário (JED e dentina situada cervicalmente a ela) concordaria com o achado clínico de que as LCNCs atingem principalmente dentina, preferencialmente ao esmalte. 8) Por ter encontrado que, nos três carregamentos estudados, os volumes bombeados por JED e dentina foram muito semelhantes, poderia se prever que a maior parte das lesões seriam de formato arredondado, na vigência de carregamentos semelhantes.

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

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 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: 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

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.

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 Avaliou-se o efeito dos vernizes CPP-ACP/NaF e xilitol/NaF na redução da erosão e progressão da erosão. Quarenta blocos de esmalte foram divididos em quatro grupos (n=10): G1=verniz CPP-ACP/NaF (verniz MITM); G2=verniz xilitol/NaF (Profluorid®); G3=verniz NaF (Duraphat®, controle positivo) e G4=água desionizada (MilliQ®, controle negativo). As amostras foram imersas em refrigerante Sprite ZeroTM (pH 2.58, 4x/dia, 3 dias), entre imersões, os espécimes ficaram em saliva artificial. Após 3 dias de erosão, a área erodida foi dividida em duas (metade recebeu uma camada adicional de verniz, enquanto a outra metade repetiu o mesmo ciclo de erosão de 3 dias). A técnica de perfilometria 3D de não contato foi utilizada para determinar a perda de estrutura dentária (PED) e rugosidade superficial (RS). Microscopia eletrônica de varredura (MEV) e imagens em 3D foram utilizadas para avaliar a topografia das amostras. Testes de Mann-Whitney, One-way ANOVA e Tukey foram utilizados (nível de significância de 0,05%). Imagens do MEV e 3D foram avaliadas descritivamente. Após 3 ou 6 dias de erosão, todos os vernizes testados foram melhores que G4 (p<0,05) para PED e RS. Além disso, o G1 apresentou menores valores de PED do que o G3 (p<0,05) após 3 dias de erosão. Observando as imagens em MEV e 3D, todos os grupos apresentaram porosidade, irregularidades e depressões no esmalte superficial após 3 e 6 dias de erosão, sendo mais pronunciados no G4. Uma aplicação tópica de vernizes fluoretados foi eficaz na redução da rugosidade e PED do esmalte após desafios de erosão. Além disso, o grupo CPP-ACP/NaF teve melhor desempenho na redução da PED quando comparado ao verniz de NaF e a água, após 3 dias de erosão.

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

RESUMO

PURPOSE: To evaluate the effects of stomach and duodenal fluid on enamel surfaces, simulating the action of refluxed liquid in patients with duodenogastric reflux. METHODS AND MATERIALS: Forty bovine incisors were used to obtain enamel fragments. Only half of the enamel surface was exposed to erosive challenges; the samples were then randomly divided into the following four groups (n = 10): G1: HCl; G2: HCl + pepsin; G3: HCl + ox bile + NaHCO3; and G4: HCl + pancreatin + NaHCO3. The specimens were placed in 37°C solutions, six times per day, for 20 s, over a period of 5 days and then analysed for morphology, surface roughness and the step formed on the dental enamel using confocal laser microscopy. The data were analysed using the Kruskal-Wallis and Dunn's test (p <0.05). RESULTS: Both analyses revealed a higher step and surface roughness for the G3 group (5.6 µm ± 1.69, 2.2 µm ± 1.61), which were statistically significant compared with the G1 and G2 groups (3.9 µm ± 1.5 µm; 1.0 µm ± 0.18; 3.7 µm ± 1.45; and 0.9 µm ± 0.12) (p <0.05); only the step in the G4 group (4.9 µm ± 1.8 µm) was similar to that of the G3 group (p >0.05). Morphological analysis showed greater structural loss in the G3 and G4 groups. CONCLUSIONS: Bile and pancreatin, in combination with hydrochloric acid, may promote a greater loss of structure, increased surface roughness and loss of enamel prismatic anatomy.

RESUMO

The aim of the present transversal study was to evaluate the clinical and biochemical salivary parameters of children with and without erosive tooth wear (ETW). The study population was children aged 4 to 9 years. A trained and calibrated examiner (kappa value for intraexaminer reliability = 0.89) classified the children into ETW (n = 24) and control groups (n = 24), and applied the O'Brien index. The salivary flow rate was initially evaluated by stimulated sialometry (paraffin chewing). Afterwards, the collected saliva was submitted to biochemical analyses of pH, uric acid, total buffering capacity, ferric-reducing antioxidant power, reduced glutathione, calcium, and phosphorus. Among the ETW children, 20 (83%) had dental lesions restricted to enamel, and 4 (17%) presented lesions affecting both enamel and dentin. A statistically significant difference between the groups was obtained only for the pH values (t-test; p = 0.004), with averages of 7.31 and 7.56 for the control and the ETW groups, respectively. Considering the parameters evaluated in general, it is suggested that the salivary profile of children with ETW does not differ considerably from that of children without ETW. However, the pH mean value seems to be slightly higher in ETW children, but is still within the normal physiological range.

RESUMO

The increased consumption of citrus sweets can contribute to the development of erosive tooth wear (ETW). Objective This in vitro study evaluated the erosive potential of citrus sweets on bovine enamel samples regarding the quantification of wear. Methodology Ninety bovine crowns were prepared and samples were randomly distributed into 6 groups (n=15): 0.1% citric acid solution (pH 2.5); Coca-Cola ® Soft Drink (pH 2.6); Fini ® Diet (lactic and citric acid, pH 3.3); Fini ® Jelly Kisses (lactic and citric acid, pH 3.5); Fini ® Fruit Salad Bubblegum (maleic acid, pH 2.6); Fini ® Regaliz Acid Tubes (maleic and citric acid, pH 3.1). Sweets were dissolved in the proportion of 40 g/250 mL of deionized water. Enamel samples were submitted to erosive challenges for 7 days (4 daily acid immersion cycles for 90 s each). Enamel wear was measured using contact profilometry (µm), and data (median values [interquartile range]) were submitted to Kruskal-Wallis/Dunn's test (p<0.0001). Results All citrus sweets tested present a high erosive potential, Fini Diet ® (2.4 [1.2]) and Fini Regaliz Tubs ® (2.2 [0.5]) show the highest erosive potential, similar to 0.1% citric acid (2.3 [0.7]); Fini Regaliz Tubs ® is more erosive than Coca-Cola ® (1.4 [0.9]). Conclusion The evaluated citrus sweets have great erosive potential and play a key role in the development of ETW.

RESUMO

Purpose: To evaluate the cumulative incidence and progression of erosive tooth wear (ETW) and identify risk factors over 18 months in a cohort of 11- to 14-year-old schoolchildren in Mexico. Methods: The study was conducted in public schools located in northern Mexico City. Permanent teeth of 424 schoolchildren were examined using the basic erosive wear examination. The possible risk factors were included in the logistic models: the consumption of acidic food and beverages; habits related to the consumption of beverages; medication; gastroesophageal reflux; frequent vomiting; and characteristics of the saliva. Results: The prevalence of ETW was 62.5 percent (265 out of 424). The cumulative incidence was 35.2 percent (56 out of 159) and the progression was 72.8 percent (193 out of 265). The consumption of acidic beverages increased the relative risk (RR) of both the cumulative incidence (RR equals 1.09; 95 percent confidence interval [95% CI] 1.02 to 1.18; P=0.005) and the progression (RR equals 1.16; 95% CI 1.01 to 1.34; P=0.003). Conclusions: This population has a high risk of the development and progression of ETW, found in approximately one-third and approximately two-thirds of the schoolchildren, respectively. The most important risk factor was the consumption of acidic beverages.

RESUMO

Objective There is increasingly common the consumption more times a day of foods and acidic drinks in the diet of the population. The present study aimed to evaluate and compare the effects of a calcium mesoporous silica nanoparticle single application of other calcium and/or fluoride products in reducing the progression of dental erosion. Methodology Half of the eroded area was covered of 60 blocks of enamel, after which the block was submitted to the following treatments: (Ca2+-MSN), casein phosphopeptide-amorphous calcium phosphate (CPP-ACP); CPP-ACP/F-(900 ppm F-); titanium tetrafluoride (TiF4 1%) (positive control); sodium fluoride (NaF 1.36%) (positive control); and Milli-Q® water (negative control) before being submitted to a second erosive challenge. A surface analysis was performed via a three-dimensional (3D) noncontact optical profilometry to assess the volumetric roughness (Sa) and tooth structure loss (TSL) and and through scanning electron microscopy (MEV). An analysis of variance (ANOVA) and Tukey's test were performed. Results Regarding Sa, all experimental groups exhibited less roughness than the control (p<0.05). The TSL analysis revealed that the Ca2+-MSN and NaF groups were similar (p>0.05) and more effective in minimizing tooth loss compared with the other groups (p<0.05). Conclusions The Ca2+-MSN and NaF treatments were superior compared with the others and the negative control.

RESUMO

PURPOSE: The in-situ efficacy of an experimental stannous (Sn)-containing sodium fluoride (NaF) dentifrice against erosion and erosive tooth wear was compared with a conventional NaF dentifrice. MATERIALS AND METHODS: This was a randomised, controlled, double-blind, parallel-group clinical trial. Mandibular appliances containing four enamel specimens (2 per side [L/R] of the appliance) were worn by 60 generally healthy adult subjects. Subjects were randomised to treatment based on age and gender. Treatments included a Sn-containing NaF or conventional NaF dentifrice. Conditions of erosion (dentifrice slurry treatment) and erosion/tooth wear (dentifrice slurry plus brushing) were compared. Dentifrices were used twice per day for 30 s of lingual brushing, followed by 90 s of slurry exposure. In addition, the two specimens on the left side of the mouth were brushed for 5 s each, using a power toothbrush. All specimens were exposed to four daily erosive challenges with commercial orange juice (pH 3.6). Tooth wear was measured as enamel loss using non-contact profilometry on day 10. RESULTS: At the day 10 visit, the adjusted mean (SE) enamel loss for specimens receiving slurry (erosion) treatment was 4.7 µm (0.61) [Sn-containing NaF] and 8.73 µm (1.12) [NaF control], with results demonstrating a statistically significant benefit for the Sn-containing dentifrice (46.2% benefit; p = 0.009). For specimens exposed to erosion/tooth wear conditions, enamel loss = 6.68 µm (1.29) (Sn-containing NaF) and 10.99 µm (1.29) (NaF group), with results statistically significant (p = 0.048; 39.2% better, favouring the Sn-containing dentifrice). When data were combined, enamel loss (SE) for all specimens subjected to erosion + erosion/tooth wear was 5.61 µm (0.77) (Sn-containing NaF]) and 9.9 µm (1.3) (NaF group). The difference again was statistically significant, favouring the Sn-containing group (p = 0.022; 43.4% better). CONCLUSIONS: The Sn-containing dentifrice demonstrated significantly better protection than did NaF under erosive and erosive/tooth wear conditions.
