“…It is known that a vegetarian diet results in more alkaline urine which, in turn, leads to increased urinary fluoride excretion [Whitford, 1990[Whitford, , 1996. In support of these physiological findings, Awadia et al [1999] reported that, in a Tanzanian population, non-vegetarians had a 7 times greater risk of developing dental fluorosis compared with vegetarians. Thus, caution is needed when using the findings in the present publication in populations consuming a 'nonwestern ised' diet.…”

Relationships between Fluoride Intake, Urinary Fluoride Excretion and Fluoride Retention in Children and Adults: An Analysis of Available Data

The aim of this study was to examine the relationship between total daily fluoride intake (TDFI), daily urinary fluoride excretion (DUFE) and fractional fluoride retention (FFR) using available data, in order to clarify the ability of DUFE to predict TDFI and, therefore, the risk of fluorosis development. Examination of published reports of simultaneous measurement of TDFI and DUFE, together with data from two unpublished Chilean studies, yielded data for 212 children aged less than 7 years and for 283 adults aged 18–75 years, providing a total of 212 and 269 data points, respectively. The relationship between DUFE and TDFI was studied for children and adults, separately. Daily fluoride retention (DFR) was estimated as a function of TDFI in children and adults assuming an average 90% fluoride absorption, and the numerical relationships between the estimated FFR and the TDFI were explored. Limiting FFR values of 0.55 and 0.36 were found for children and adults, respectively, above a threshold of TDFI of 0.5 and 2 mg, respectively. Neutral fluoride balances were predicted when the TDFI was equal to approximately 0.07 mg F/day for children and 0.8 mg F/day for adults. For children and adults, it is possible to obtain reasonably good estimations of community-based TDFI and DFR, using DUFE data. The advantages and limitations of these relationships, together with the need for future studies, are discussed.

“…In North Tanzania, a study of 165 schoolchildren (aged 6-18 years) found that the prevalences of moderate (TFI score 1-4 score) and severe (TFI score 5-9) dental fluorosis were 67%, and 21% respectively among vegetarian children, and were lower than the prevalences of moderate and severe dental fluorosis among non-vegetarian children (95% and 35% respectively) [25]. This could explain the negative significant associations between the level of consuming plant protein and dental fluorosis in the current study.…”

A high prevalence of dental fluorosis has been identified among children in the Gaza Strip. This study aimed to determine the history of breastfeeding and dietary behaviours among children in the Gaza Strip and to examine potential associations with the prevalence and severity of dental fluorosis. A cross-sectional study recruited a stratified cluster random sample of 350 children aged 12-18 years and their mothers. Data about dietary behaviours in the first 7 years of life were collected by interview questionnaire. Dental fluorosis was determined using the Thyllstrup-Fejerskov index. A majority of children were breastfed exclusively in the first 6 months (82.9%) but 98.1% were given tea in the first year of life. The prevalence of dental fluorosis was 78.0%. Both intake of animal proteins and plant proteins were negatively associated with the prevalence and severity of dental fluorosis. Further studies to investigate fluoride intake is required to plan preventive interventions. Comportements alimentaires et fluorose dentaire chez des enfants de la Bande de Gaza RÉSUMÉ Une prévalence élevée de fluorose dentaire a été observée chez des enfants de la Bande de Gaza. La présente étude visait à déterminer les antécédents d'allaitement au sein et les comportements alimentaires chez des enfants de la Bande de Gaza puis à examiner les associations possibles avec la prévalence et la sévérité de la fluorose dentaire. Une étude transversale a recruté 350 enfants âgés de 12 à 18 ans et leurs mères, formaient un échantillon randomisé et stratifié en grappes. Les données sur les comportements alimentaires au cours des sept premières années de vie ont été recueillies par questionnaire lors d'un entretien. La fluorose dentaire a été déterminée à l'aide de l'indice Thylstrup-Fejerskov. Une majorité des enfants avait été nourrie exclusivement au sein au cours des six premiers mois de vie (82,9 %) mais 98,1 % avaient consommé du thé pendant leur première année. La prévalence de la fluorose dentaire était de 78,0 %. Les apports en protéines animales et végétales étaient négativement associés à la prévalence et la sévérité de la fluorose dentaire. Des études supplémentaires évaluant l'apport en fluor sont requises pour prévoir des interventions préventives.

“…O risco de desenvolvimento de fl uorose dentária parece ser bastante menor entre vegetarianos 18 , contudo, foi encontrado apenas um estudo sobre este tema, o que não permite tirar conclusões definitivas. Além disso, outros fatores (além da dieta) contribuem para o aparecimento da fl uorose, como a ingestão de dentifrí-cios e soluções para bochechos, e mesmo a ingestão de água, bebidas e alimentos processados industrialmente em regiões abastecidas por água fl uoretada 27 , e estas variáveis não foram controladas pelo estudo analisado nesta revisão.…”

ResumoA infl uência do padrão dietético nas condições bucais é um assunto com respostas inconclusivas na literatura científi ca atual. O objetivo desta revisão sistemática foi avaliar os estudos abordando o impacto da dieta (vegana, ovolactovegetariana e onívora) nas condições de saúde bucal (erosão, cárie, fl uorose e condição periodontal). Foi realizada busca nas bases de dados Pubmed, Scielo, Lilacs e Proquest. Há algumas evidências de que a dieta vegetariana seja um fator de proteção para cáries e um fator predisponente à erosão dentária. Embora não existam dados conclusivos, é possível que os vegetarianos sejam menos sujeitos à fl uorose e à doença periodontal, e esse fato pode estar relacionado com o aumento do fl uxo salivar. Descritores: Saúde bucal • Dieta vegetariana • Hábitos alimentares. AbstractThe infl uence of dietary patterns in oral conditions is a subject that presents inconclusive answers in the present scientifi c literature. The aim of this systematic review was to evaluate studies regarding the impact of diet (vegan, lactoovovegetarian and omnivore) in oral health conditions (erosion, carie, fl uorosis and periodontal condition). We performed a search in Pubmed, Scielo, Lilacs and Proquest data bases. There is some evidence that vegetarian diet is a protection factor against caries and a predisposing factor to dental erosion. Although there are no conclusive data, it is possible that vegetarians are less predisposed to fl uorosis and periodontal disease, and this might be related to the increase in salivary fl ow.

Vegetarianism and dental fluorosis among children in a high fluoride area of northern Tanzania

Abstract: The significantly lower prevalence and severity of dental fluorosis among the vegetarian group compared to the nonvegetarians would seem to be related to diet.
