Objective: To estimate the erosive potential of fruit juices consumed by a group of Brazilian children. Methods: The study was carried out in two phases: Different fruit types were selected based on a dietary questionnaire applied to a random group of 40 patients' mothers attending public pediatric services; the thirteen most cited fruits (acerola, orange, passion fruit, mango, cashew apple, grape, guava, soursop, pineapple, apple, lemon, tangerine and papaya) were purchased at local markets of João Pessoa, Northeast region of Brazil. The concentrated juices were prepared using a processor. The material was centrifuged for pH and fluoride measurements (in duplicate) using a pH electrode and an ion sensitive electrode, respectively. Comparisons of mean±SD were done by ANOVA and Schefé test. Results: Acerola was the most cited fruit (n=24). The pH of the fruit juices varied from 2.21 (lemon) up to 5.52 (papaya) (p<0.01). Only papaya juice showed pH above 5.5. Fluoride concentrations varied from 0.04 (mango) up to 0.42 mg/L (lemon) (p>0.01). Conclusions: The fluoride concentration was low for all fruits juices evaluated. Except for papaya, the majority of the concentrated fruits juices presented critical pH values indicating some erosive potential.Key words: Dental enamel; diet; fruit; fluoride; pH; tooth erosion.

Métodos: O estudo foi conduzido em duas fases: diferentes tipos de frutas foram selecionados baseados em questionário de dieta aplicado em grupo randomizado de 40 mães de pacientes atendidos no serviço público de Pediatria; as 13 frutas mais citadas (acerola, laranja, maracujá, manga, caju, uva, gioaba, graviola, abacaxi, maça, limão, tangerina e mamão) foram adquiridas em supermercados de João Pessoa, Brasil. Os sucos concentrados foram preparados usando processador. O material foi centrifugado para mensuração do pH e concentração de flúor (duplicata) usando eletrodo de pH e de íon seletivo de flúor, respectivamente. Comparação de médias ± desvio-padrão foi feita por ANOVA e teste de Scheffé. Resultados: Acerola foi a fruta mais citada (n=24). O pH dos sucos de frutas variou de 2,21 (limão) a 5,52 (mamão) (p<0,01). Apenas o suco de mamão apresentou pH acima de 5,5. A concentração de flúor variou de 0,04 (manga) a 0,42 mg/L (limão) (p>0,01). Conclusões: A concentração de flúor foi baixa para todos os sucos avaliados. Exceto para mamão, a maioria dos sucos de frutas concentrados apresentou valor de pH crítico, indicando algum potencial erosivo.Palavras-chave: Esmalte dental; dieta; fruta; flúor; concentração de íons hidrogênio; erosão dentária. 107Rev Odonto Cienc 2014;29(4):106-109 Brazilian fruit juices fluoride and tooth erosion | Farias et al.

“…However, it should be noted that compared to artificial saliva, an in situ model with fresh saliva is expected to have a different potential for remineralization, since it contains various proteins that are thought to inhibit mineral deposition on the tooth surface 30) . The results of the current study are in line with those of microradiographic studies on the mineral content of enamel after erosion and subsequent immersion in cleared human saliva 31) , or exposure to the oral cavity 32) , where mineral gain and a 20 to 70% reduction in demineralization depth were reported. Nevertheless, this finding is in contrast to previous research work that suggested human saliva 26,27) , and specifically stimulated saliva 6,33) on its own did not possess the ability to remineralize the enamel surface in the oral environment.…”

This in situ study aimed to evaluate effects of waiting periods after erosive challenge before toothbrushing on enamel abrasion and nanoindentation hardness. Ten subjects wore intraoral appliances each with a set of 4 bovine enamel blocks. The enamel blocks were subjected to 2 cycles a day for 3 days as follows; intraoral exposure to form acquired pellicle and extraoral erosion followed by either 0, 3, 30 or 60 min intraoral exposure and then brushing, which was performed using an automatic brushing machine. Abrasive loss was assessed by white light interferometry. Nanoindentation was performed to calculate relative hardness. Abrasion and relative hardness were statistically analyzed by ANOVA. Abrasive loss was significantly less in groups exposed to saliva compared with 0 min (p<0.05); there was no significant difference between 30 and 60 min (p>0.05). Relative hardness was statistically higher after intraoral exposure, but no differences existed among any intraoral exposure periods (p>0.05).

“…This data demonstrated that the application of several acid beverages for a relatively short exposure of time is sufficient to remove the smear layer and to induce several alterations to the dentin surface. The specimens were kept immersed in acidic beverages for 5 min because this is the time necessary for the saliva to neutralize and/or remove the acid of the tooth surfaces (14). All the acidic beverages tested in this study increased the permeability after a single Table 2.…”

Effect of an acid diet allied to sonic toothbrushing on root dentin permeability: an in vitro study

This study quantified alterations in root dentin permeability after exposure to different acid beverages. Twenty-five third molars were sectioned below the cementoenamel junction, the root segment was collected, and the pulp tissue was removed. The root segments were connected to a hydraulic pressure apparatus to measure the permeability of root dentin after the following sequential steps, with 5 specimens in each: 1) phosphoric acid etching for 30 s (maximum permeability), 2) root planning to create new smear layer, 3) exposure to different acid substances for 5 min (orange, cola drink, vinegar, white wine, lemon juice), 4) toothbrushing with sonic toothbrush for 3 min, 5) toothbrushing with sonic toothbrush plus dentifrice for 3 min. Considering step I as 100%, the data were converted into percentage and each specimen was its own control. Data were analyzed statistically by Kruskal-Wallis and Dunn's post test at 5% significance level. All acidic substances increased dentin permeability significantly after scraping (p<0.05). Toothbrushing after exposure to acid substances decreased dentin permeability and the association with dentifrice accentuated the decrease (p<0.05), except for the specimens treated with cola drink. Thus, it may be concluded that all tested acid fruit juices increased dentin permeability, and toothbrushing with or without dentifrice can decrease root dentin permeability after dentin exposure to acid diet.
