“…Tooth wear is the loss of dental hard tissues resulting of the interaction between teeth and other materials (abrasion), tooth-to-tooth contact (attrition) or dissolution of hard tissues by acidic substances (erosion) [1,2]. Tooth wear is a relatively common condition [3][4][5] and its prevalence increases with age [3,6].…”

Objective: To explore the association between tooth wear and quality of life among adults in the United Kingdom, independently of sociodemographic factors and other common oral conditions. Methods:We used data from 5,654 dentate adults who participated in the 2009 Adult Dental Health Survey. Tooth wear was assessed during clinical examination and classified as none, mild, moderate and severe based on the worst affected tooth recorded. The numbers of teeth with mild, moderate and severe tooth wear were used as alternative measures. Oral impacts on quality of life were measured using the short form of the Oral Health Impact Profile (OHIP-14). The associations between tooth wear measures and OHIP-14 total and domain scores were tested in negative binomial regression models adjusting for sociodemographic and clinical factors.Results: Overall, 62% of participants had mild, 13% moderate and 2% severe tooth wear. Adults with severe tooth wear had a crude OHIP-14 total score higher than those without tooth wear (Rate Ratio:1.90; 95% Confidence Interval: 1.32-2.75). This association was attenuated after adjustment for confounders, particularly for other oral conditions (1.25; 95%CI: 0.90-1.73). Moreover, adults with severe tooth wear reported higher OHIP-14 domain scores in psychological discomfort (1.15; 95%CI:1.06-1.25) and psychological disability (1.18; 95%CI: 1.10-1.30) than those without such condition.There was also evidence of a dose-response relationship; with higher OHIP-14 domain scores according to the number of teeth with severe tooth wear. Conclusion:This nationwide study among UK adults shows that severe tooth wear was negatively associated with psychological impacts on people's life.Clinical significance: Dentist should consider not only the patients' clinical characteristics, but also their impacts on quality of life and provide preventive or restorative management accordingly.2

“…Brushing without toothpaste has very small clinical effects on dentine but features of the toothbrush can modulate the abrasivity of the toothpaste [14]. Several factors such as brushing force, means of transmitting the power to the dentine surface and the circumstance in which the abrasive particles were placed might affect the rate of dentine wear by dentifrice abrasiveness.…”

This study was carried out to evaluate the influence of factors (such as tip form, brush tension and slurry viscosity) transmitting brushing force onto eroded dentine surface by measuring thickness of substance loss using an electron probe micro-analyzer.Dentine slabs each with an exposed window (4 mm 2 ) made using nail varnish were eroded through immersion into 0.83 M acetic acid for 30 minutes. Half of the window area was then covered with nail varnish and served as the control area. The slabs were fixed and the tips (flat trim or tapered) of the bristles were placed on the eroded window, applying adequate pressures (2 g or 4 g per mm 2 ) respectively. The slabs were then brushed for one minute using a sonic toothbrush (480 Hz) with slurry containing silica abrasive and aqueous solutions of carboxymethylcellulose (0.5% or 1%) in a ratio of 10 g to 50 mL. The slabs from which the nail vanish was removed were then sputter-coated with platinum and embedded in methacrylate to be cross-sectioned in the middle of the windows. The cross-sectional surface was polished, coated with carbon and examined using backscattered electron imaging to measure the thickness of dentine loss in the brushed and the control areas within the window.The loss values (µm, mean ± SD) in the treated and the control areas were 24.6 ± 3.61 and 21.5 ± 3.36 respectively. ANOVA analysis indicated that abrasion thicknesses defined as the differences of loss values between brushed and control surfaces were affected only by tip form with no significant interactions among the other factors. Eroded dentine wear by a sonic toothbrush was deeper with tapered tip (3.82 ± 2.73) than with flat trim (2.40 ± 1.54).The results suggested that the influence of factors transmitting brushing force on eroded dentine wear was limited.

RESUMO:O presente estudo avaliou o potencial erosivo de chás industrializados no esmalte dentário, de acordo com o percentual de perda de dureza superficial (%PMD), pH, titulação ácida e capacidade tampão. Foram analisados seis tipos de chás industrializados, de diferentes marcas e sabores. A água mineral-Crystal ® e a Coca-Cola ® foram os controles negativo e positivo, respectivamente. As medições de pH e titulação ácida foram feitas em triplicata, em 50 mL da bebida. A capacidade tampão foi calculada baseada nos valores de pH e titulação ácida para o pH 7,0. A microdureza da superfície o esmalte foi medida antes e após o teste erosivo. Os testes Anova e a correlação de Pearson, com p<0,05, foram usados para analisar os dados. Os dados apresentaram uma distribuição normal. Foi verificada diferença significativa entre os chás e os controles utilizados, em todas as variáveis analisadas (ANOVA, p<0,05). O pH dos chás variou de 2,25 (chá preto com limão) a 3,39 (chá mate com limão). Os maiores valores de titulação ácida (2,05) e capacidade tampão (8,30) foram apresentados pelo chá preto com limão. O maior %PMD foi encontrado no chá de pêssego e o menor no chá natural do mate. Foram verificadas diferenças estatisticamente significante no %PMD de todos os chás com o controle negativo. O %PMD de todos os chás foi superior ao controle positivo. Correlações significativas (p<0,05) foram observadas entre pH inicial com titulação ácida e capacidade tampão, e %PMD com pH inicial, titulação ácida e capacidade tampão. Assim, todos os chás analisados apresentaram caráter erosivo no esmalte dentário, variando a sua intensidade conforme o sabor e/ou composição dos mesmos. PALAVRAS-CHAVE: Erosão dentária; Bebidas; Esmalte dentário. ALTERATIONS IN SURFACE MICRO-HARDNESS OF DENTAL ENAMEL EXPOSED TO INDUSTRIALIZED TEASABSTRACT: The erosion capacity of industrialized teas on the dental enamel is evaluated according to the percentage of dental surface hardness loss (%DHL), pH, acid titration and buffer capacity. Six types of industrialized teas, featuring different brands and tastes, were analyzed. Mineral water-Crystal ® and Coca-Cola ® were respectively the negative and positive controls. Measurements of pH and titration were prepared in triplicate, in a 50ml beverage. Buffer capacity was calculated on pH rates and acid titration for pH 7.0. Micro-hardness of enamel surface was evaluated prior to and after the erosive test. ANOVA and Pearson´s correlation tests at p<0.05 were employed to analyze data which, in turn, provided normal distribution. There was significant difference between the teas and controls in all variables (ANOVA, p<0.05). The pH of teas ranged between 2.25 (Black tea with lemon) and 3.39 (Matte with lemon). Highest rates for acid titration (2.05) and buffer capacity (8.30) occurred in Black tea with lemon. Highest %DHL rate occurred in Peach tea, whilst the lowest in Natural Matte tea. There was a statistically significant difference in %DHL for all teas when compared to negative control and %PMD of all types of ...
