Abstract:
Dental fluorosis is a common disorder caused by excessive fluoride intake during tooth development. The esthetic consequences of dental fluorosis can negatively affect oral health-related quality of life and have lasting psychosocial effects. In severe cases, where the fluorosed enamel is prone to chipping, flaking, and developing caries, minimally invasive procedures are ineffectual and a more substantial restorative approach is required to restore optimal function and esthetics. However, no definitive guidelines exist for the management and treatment of severe dental fluorosis due to the limited evidence available in the literature. This case report describes the full-mouth rehabilitation of a patient with severe dental fluorosis utilizing adhesively bonded all-ceramic crowns, veneers, and overlays. The successful follow-up on this case indicates that adhesively bonded restorations may provide a viable option in the functional and esthetic management of severely fluorosed dentition.

Abstract:
Objectives: To assess the incidence of dental fluorosis in schoolchildren aged12 to 15 years resident of Gojra, Pakistan. Study Design: Cross sectional study. Setting: 10Different Public Schools of the City Gojra. Period: May to July 2017. Method: 526 volunteerswere examined in ten public schools of Gojra. The examination was performed in the schoolplayground by three dentists after tooth brushing under observation by a hygienist. Beforeexamination cotton pellets were applied on the teeth surfaces to remove the moisture and makethem perfectly dried and were examined in day light, with the use of an explorer, a mouth mirrorand tongue depressor. Dental fluorosis score was formulated using Dean’s index. Result: Dentalfluorosis was documented in nearly 18.44% of the examined schoolchildren. Maximum childrenwere presented with questionable condition (7.60%) and then followed by very mild (5.13%).The severity rate was 0.76%. Conclusion: Incidence of dental fluorosis was in accordance withother studies results done in the past. Fluoride is a crucial mineral and helps in controlling thecaries but it’s use must be in the normal range according to the demand of that area.

Abstract:
Abstract Aim To provide diagnosis as well as differential diagnosis of dental fluorosis. Background Dental fluorosis is a developmental defect of enamel, due to consecutive exposures of tooth during the formative stage of development to the higher concentration of fluoride, resulting in enamel with lesser mineral content and enhanced porosity. Several epidemiological indices have been utilized for diagnosis and assessment of dental fluorosis on the basis of clinical appearance. Fluorosis of the deciduous teeth occurs less commonly and is milder than that of permanent teeth. Highlights The diagnostic difficulties are usually associated between fluorotic and nonfluoride opacities. A complete history of the clinical condition, teeth affected with specific areas, pattern of lesion, color and its method of detection are the few important diagnostic criteria for differentiating dental fluorosis from nonfluoride discolorations of the teeth. Conclusion This review article has enlightened the diagnosis and differential diagnosis of dental fluorosis among various nonfluoride tooth discolorations. A correct diagnosis results in an appropriate and early management of dental fluorosis and plays an important role in oral epidemiology and public health.

Abstract:
The currently popular scoring systems used to diagnosis fluorosis use different measurement units, evaluate variable numbers of sites per person, and involve non-comparable groupings of clinical symptoms. Although none of these factors is related to the level of fluoride exposure in the examined population, their combined effect produces fluorosis prevalence values for a population which vary considerably among and within these scoring systems. Intrinsic factors for a scoring system include the inclusion of a questionable category, the minimal level of fluorotic involvement, and the number of affected sites within a subject required for case definition. Thus, a case definition of fluorosis for each scoring system, although not mandatory, would certainly be desirable so that dental epidemiologists and clinical investigators can interpret fluorosis scores relative to risk assessment. On the other hand, ratios of fluorosis prevalence magnitudes, as evidenced by odds ratios, can be more stable between scoring systems when groups with different fluoride exposure levels are compared. There is a strong correlation between extent and specific measures of fluorosis severity for Dean's Index (DI) and the Tooth Surface Index of Fluorosis (TSIF) scoring system, as well as within each scoring system separately. Parallel patterns in fluorosis severity were found among groups with different fluoride exposures for the DI and TSIF scoring systems. The effects of fluoride exposure on severity levels of fluorosis may be better understood by using relative measures rather than by using differences in severity levels.

Abstract:
Background and objectives: Fluorosis is an important clinical and public health problem in several parts of the world. Although the relationship of fluoride level in drinking water to dental caries and dental fluorosis is known, relationship of fluorosis with the caries is not clear. This study was conducted to evaluate and compare the thickness of enamel and depth of lesion after inducing artificial caries in fluorotic and nonfluorotic teeth. Methods: Study group included 15 fluorosis affected and 15 normal teeth. Artificial caries was induced and teeth were sectioned to 150 microns and observed under polarized light microscope to measure the enamel thickness and depth of lesion in microns. Results: Statistical analyses of the measurements were made using student's unpaired t-test. Thickness of the enamel of nonfluorotic teeth was found to be significantly more when compared with the fluorotic teeth(p-value 0.0404) and depth of lesion was significantly more in fluorotic teeth when compared with the nonfluorotic teeth(p-value 0.0218). Conclusion:Although fluoride is acknowledged as an essential factor in the prevention of dental caries there has to be careful balance in the amount consumed to ensure that fluorosis does not occur.

Abstract:
The aim of this study was to test whether the concentrations of fluoride in fluorotic human enamel are related to the degree of severity of dental fluorosis classified according to the index described by Thylstrup and Fejerskov. Teeth representing the entire spectrum of human dental fluorosis were analyzed. Fluoride concentrations were determined by serial acid-etching from surface to interior of blocks of enamel cut from each tooth. Fluoride was measured by ion electrode and calcium by atomic absorption spectrophotometry. The results showed that the pattern of distribution of fluoride in fluorotic enamel is similar to that described for normal enamel. Increasing severity of fluorotic lesions was associated with increasing concentrations of fluoride throughout the enamel. It is concluded that although further studies are required to establish the relative contribution of fluoride which may be taken up posteruptively by fluorotic enamel, the findings support the hypothesis that the TF index reflects increasing exposure to fluoride during tooth development.

Abstract:
ABSTRACT High intake of fluoride causes developmental disturbances of tooth enamel leading to dental fluorosis. It produces mottling of enamel and its occurance depends upon the quantity of fluoride ingested and the stage of tooth development. Esthetic management of mottled teeth is planned according to the severity of discoloration and the extent of surface aberrations. A combination of different techniques makes the teeth lighter in shade with a smoother surface. This case report describes the management of fluorosed teeth which is discolored and pitted on the surface by minimally invasive procedures.

Introduction: Dental fluorosis is a developmental disturbance of enamel that results from ingestion of high amounts of fluoride during tooth mineralization. Drinking water remains the main source of fluoride. Other sources of fluoride include infant formula, vegetables; canned fish as well as early, improper utilization of fluoridated toothpastes in children. Knowledge of risk factors in the causation of dental fluorosis may improve strategies to prevent dental fluorosis. Objective: To determine the prevalence of dental fluorosis among children aged 12-15 years old in Athi River sub-county, Machakos County, Kenya and assesses the level of knowledge on risk factors for dental fluorosis among their parents. Methodology: This was a descriptive study with an analytic component. A total of 281 children aged 12-15 years attending public primary schools within Athi River sub-county, Machakos County were included. A self-administered questionnaire was send to parents for socio-demographic characteristics and oral health practices. Children whose parents consented were examined and dental fluorosis scored according to the Thylstrup and Fejerskov index. Fourty randomly selected children were requested to bring water samples from their homes. Retail stores located in the area were visited for purchase of six different brands of bottled water. These samples were sent to a certified laboratory for fluoride analysis and reported in milligrams of fluoride per litre. Data analysis: Data was entered into SPSS version 20 and analysed for means, ANOVA of means and chi-square test of significance for categorical variables. All tests for significance were set at 95% confidence level (α≤0.05). Results: A total of 314 self-administered questionnaires were send to parents together with consent forms for their children‟s participation in the study. Two hundred and eighty six responded positively, giving a response rate of 91%. The overall prevalence of dental fluorosis among children aged 12-15 years was 93.4% with only 6.6% (n=19) recording a TFI score of 0. About one quarter 70(24.4%) of children had severe fluorosis with TFI scores of ≥5. The mean TFI score for all children was 3.09 (SD=2.0), with males recording a mean TF score of 3.01 (SD=2.11) and females a mean TF score of 3.16 (SD=1.88). Out of 44 water samples analysed, 29 (65.9%) had a fluoride content of less than 0.6mg/l, 5 (11.4%) had fluoride content of 0.7 - 1.5mg/l while 10 (22.7%) of samples had a fluoride content ≥1.5mg/l. The highest fluoride content recorded was 9.3mg/l, with another sample reflecting 8.9mgF/l. Three of the bottled water samples had a fluoride content of less than 0.6mg/l, while the other half of the bottled water reported 0.7 - 0.8mg/l fluoride. A majority (87.8%) of parents indicated that they had noticed children with brown staining of their permanent teeth in their community. About 80% of parents thought dental fluorosis was caused by salty water, while only 12.9% correctly identified water with high fluoride content as being responsible for the discolored teeth. Conclusion: Although about one in five water sources sampled had fluoride content of ≥1.5mg/l, the prevalence of dental fluorosis in this community was very high. Parental knowledge on the risk factors for dental fluorosis was low. Further research is necessary to identify the water distribution networks to provide sound evidence for engaging with the county authorities on provision of safe drinking water to the community.

Abstract:
These PhD projects represent secondary analyses of data from the ongoing Iowa Fluoride Study (IFS)/Iowa Bone Development Study (IBDS). The aim of this dissertation was to explore the associations between period-specific and cumulative fluoride intakes from birth to age 17, and from birth to age 19 years and bone measures of participants. Also, this dissertation looked into the associations between the clinical presence of dental fluorosis and bone outcomes. Participants have been participating in the IBDS that grew out of the IFS, which is a longitudinal investigation of dietary and non-dietary fluoride exposures, dental fluorosis and dental caries. IFS participants were recruited during 1992-95 from 8 hospital postpartum wards in Iowa, and detailed questionnaires were sent every 1.5-6 months. Data on intakes from water, other beverages, selected foods, dietary fluoride supplements and dentifrice were collected from the questionnaires, and, in combination with water and beverage fluoride levels, combined fluoride was estimated. For the first dissertation project, the association between fluoride intake and peripheral quantitative computed tomography (pQCT)-derived bone outcomes at age 17 were assessed. Participants underwent pQCT of the radius and tibia (XCT-2000) at age 17 years. pQCT results of trabecular bone mineral density (BMD) and bone mineral content (BMC), cortical BMD and BMC, and compression and torsion strength were related to fluoride intake through bivariate and multivariable analyses, adjusting for height, weight, years since peak height velocity, average daily time spent in moderate-to-vigorous intensity physical activity, daily calcium intake, and daily protein intake. P-values < 0.01 were considered statistically significant rather than p< 0.05 due to multiple hypothesis tests. The mean daily fluoride intake estimated by area-under-the-curve (AUC) from birth to 17 years was 0.79 mg (SD = 0.32) for males and 0.70 mg (SD = 0.25) for females. Spearman correlation coefficients between daily fluoride intake and pQCT bone measures were weak (for females r= -0.01 to 0.15 for radius bone outcomes and -0.001 to 0.23 for tibia bone outcomes; for males r= 0.03 to 0.24 for radius bone outcomes and -0.008 to 0.27 for tibia bone outcomes). In sex-specific linear regression analyses for females, partially-adjusted for height, weight, and years since peak height velocity, statistically significant negative associations were detected between all radial bone outcomes and period-specific fluoride intake from 0-8.5 years. Significant positive associations were detected for females between period-specific fluoride intakes from 14-17 years and all tibia bone outcomes, and between period-specific fluoride intakes from 14-17 years and all radius and tibia bone outcomes for males. In the fully-adjusted models, which also included physical activity, protein intake and calcium intake, statistically suggestive negative associations were detected for females during the early fluoride intake period from 0 to 8.5 years and radial cortical bone content and torsion bone strength. A statistically suggestive positive association was found between period-specific fluoride intake from 8.5 to 14 years and torsion bone strength (pSSI) (p< 0.05) for females. For males, statistically significant positive associations were detected between fluoride intake for the period from 14 to 17 years and cortical content and torsion strength (pSSI) at the 0.01 level. The second project examined the associations between period-specific and cumulative fluoride intakes from birth to age 19 years and MDCT-derived bone outcomes at age 19. Age 19 MDCT-derived trabecular and cortical bone micro-architecture scans were acquired at the University of Iowa Comprehensive Lung Imaging Center. MDCT results of the trabecular (volumetric bone mineral density (vBMD), transpose bone mineral density (tBMD), plate trabecula bone mineral density (pBMD), plate width (TS-PW), trabecular thickness (Tb.Th), trabecular spacing (Tb.Sp), trabecular network area (Tb.NA)) and cortical (cortical bone porosity (Cb.Poro), cortical thickness (Cb.Th)) bone were related to fluoride intake through bivariate and multivariable analyses, adjusting for height, weight, years since peak height velocity, average daily time spent in moderate-to-vigorous intensity physical activity, Healthy Eating Index (HEI) score, calcium intake and protein intake. P-values < 0.01 were considered statistically significant rather than p< 0.05 due to multiple hypothesis tests. The mean daily fluoride intake estimated by area-under-the-curve (AUC) from birth to 19 years was 0.81 mg (SD = 0.33) for males and 0.69 mg (SD = 0.27) for females. Spearman correlation coefficients between daily fluoride intake and MDCT bone measures were weak (for females r= -0.001 to 0.20 for trabecular bone outcomes and -0.01 to 0.02 for cortical bone outcomes; for males r= -0.003 to 0.16 for trabecular bone outcomes and -0.09 to -0.02 for cortical bone outcomes). In sex-specific partially-adjusted regression analysis adjusted for height, weight, and years since peak height velocity, no statistically significant associations were found for females or males. In the fully-adjusted models, which also included physical activity, HEI score, and protein and calcium intakes, no statistically significant associations were found for either females or males. The third project explored the associations between dental fluorosis score at age 8 and DXA-derived bone outcomes at age 5. DXA bone assessments of the whole body, proximal femur (hip), and lumbar spine were performed at The University of Iowa in the Clinical Research Center (Hologic QDR-2000 DXA unit). The dental fluorosis score was defined as the proportion of zones with definitive or severe fluorosis per person. In the unadjusted associations between bone outcomes and dental fluorosis score, no statistically significant associations were detected for females at the 0.05 level. For males, a statistically significant negative association was found between hip BMD and dental fluorosis score. Sex-specific partial correlation coefficients were estimated between DXA-derived bone outcomes and dental fluorosis score adjusted for height, weight, physical activity, calcium intake and fluoride intake. No statistically significant associations were found for females. For males, a statistically significant negative association was detected between dental fluorosis score and hip BMD. The findings of this dissertation show that life-long intakes from combined sources for adolescents and young adults living in fluoridated areas in the United States were weakly associated with bone measures at age 17 and 19. Furthermore, it was shown that bone outcomes can’t be predicted by the score of dental fluorosis. Fluoride is a mineral that plays an important role in the mineralization of bone and teeth, as well as in dental caries prevention. Numerous professional health organizations endorse the adjusted fluoridation of public water supplies for caries prevention. Results from this dissertation will also help in supporting additional efforts to promote water fluoridation and expand its use, as this dissertation’s outcomes did not demonstrate adverse outcomes related to bone.

Dental fluorosis is an endemic condition in a number of regions of South Africa, varying in degree of affliction according to the drinking water fluoride concentration in the area. Objective: While a number of South African studies have reported on the relationship between fluorosis and fluoride concentration in the drinking water, the purpose of this study was to determine perceptions of dental fluorosis in the Central Karoo District of the Western Cape. Methods: Learners aged 12-15 years and who had been lifelong residents in their respective areas were selected from schools in Leeu Gamka, Merweville, Nelspoort and Murraysburg. All the children meeting the inclusion criteria were included realising a total sample of 189. Drinking water fluoride concentration of each town was determined and concomitant fluorosis affliction was assessed. An interviewer administered questionnaire was used to determine respondents’ self-rated perceptions of fluorosis as well as their responses to a set of statements on clinically defined fluorosis. To this end four photographs, each depicting a different degree of fluorosis: (No fluorosis; Mild fluorosis; Moderate fluorosis; Severe fluorosis) were shown to the respondents. Results: In Leeu Gamka, with the highest fluoride concentration ([F] = 1.62ppm), 82% of respondents were aware of fluorosis stains as opposed to 6%-20% awareness in Merweville ([F] = 0.68), Nelspoort ([F] = 0.70) and Murraysburg ([F] = 0.56). Two thirds of respondents in Leeu Gamka found the appearance of their teeth embarrassing compared to only 2%-10% in the other 3 areas. The majority of respondents in Leeu Gamka (82%) indicated that they would want to remove the fluorosis spots with only 4%-20% in the lower fluoride areas. Two thirds (67%) of the Leeu Gamka respondents were teased compared to 2%-6% in the other areas. Most of the respondents have not tried to do anything to the appearance of the teeth, even in the higher fluoride area of Leeu Gamka. The average response varied little for all the photographs across the geographic areas (the minimum and maximum scores varied between 4.00 and 5.00) and reflected a greater tendency towards strongly disagreeing with the statement on aesthetics-even for the photographs depicting no fluorosis and mild fluorosis. The average response varied between 1 and 2 among all four geographic regions showing a tendency to “agree” and “strongly agree” to the statement on embarrassment. The average response to the statement on neglect varied little for all the photographs across the geographic areas as the minimum and maximum average response scores varied between 1.36 and 2.39 (agree and strongly agree). The response to the statement on disadvantage varied little for all the four photographs across the geographic areas (minimum=1.00, maximum=2.07) and reflected a greater tendency toward strongly agreeing and agreeing with the statement. Conclusion: The respondents from the higher fluoride area were more aware of dental fluorosis, had a greater perception of embarrassment and the strongest desire to remove the fluorosis staining. There was little variation in the average response to the statements on clinically defined fluorosis across the geographic areas. The learners erroneously believed that dental fluorosis was due to neglect, which is an indication that many learners are not aware of the cause of dental fluorosis in their community. The general consensus of the communities was that fluorosis was judged with feelings of negativity (embarrassment and a disadvantage for the child into adulthood).

Introducción: La prevalencia de la fluorosis dental ha ido en aumento a nivel mundial como efecto asociado al amplio uso de fluoruros utilizados para evitar lesiones de caries dental. El objetivo de este estudio fue actualizar al año 2015 la prevalencia y severidad de fluorosis dental en escolares de 6 a 12 años de edad en la Región Metropolitana. Materiales y métodos: 851 escolares de 6 a 12 años de edad de 3 comunas de la Región Metropolitana fueron examinados. Se realizó examen clínico intraoral y registró COPD (OMS), presencia y/o ausencia de fluorosis y grado de severidad de acuerdo al Índice Thylstup y Fejerskov. Se determinó la distribución de la fluorosis de acuerdo a sexo, edad y nivel socioeconómico de los escolares. Los datos fueron analizados por el programa SPSS, test de Kruskal-Wallis y Mann-Whitney con un intervalo de confianza del 95%. Resultados: La prevalencia de fluorosis dental fue de un 57.6% (n=490). El 43.9% de los casos correspondieron a fluorosis grado 1 y 2. Un 11.28% correspondió a grado 3, y un 2.47% a los grados 4, 5 y 6 en conjunto. La distribución por sexo fue de 56.2% en hombres, 58.5 % en mujeres, no se encontró diferencia significativa entre ambos sexos (p=0.51). La mayor severidad se detectó a los 12 años (p=0.01). La prevalencia en el estrato I fue 40.4%, en el II 69.2% y en el III fue 63.8%, con diferencias significativas entre el estrato socioeconómico I y II, y I y III (p<0.01). En escolares con fluorosis el índice COPD fue 0.45, ceod 1.31, y en escolares sin fluorosis COPD fue 0.49 y ceod 1.58, habiendo diferencia significativa entre los índices ceod (p=0.014). Conclusión: La prevalencia de fluorosis dental en escolares de 6 a 12 años de edad en la Región Metropolitana es alta, de un 57.6%, con una mayor severidad a los 12 años de edad. No se encontró diferencia significativa entre ambos sexos. La menor prevalencia se encontró en el estrato socioeconómico alto. Escolares con fluorosis mostraron menor historia de caries que escolares sin fluorosis.

Trabajo de Investigación Requisito para optar al Título de Cirujano Dentista
Introducción: La Hipomineralización Incisivo Molar (HIM) se define como un defecto cualitativo del esmalte que afecta a uno o más primeros molares permanentes y a veces se asocia a incisivos permanentes. Su etiología no está completamente clara y la prevalencia reportada es variable. Clínicamente va desde opacidades demarcadas con límites definidos hasta restauraciones atípicas o gran pérdida de estructura coronaria. Al ser un esmalte más poroso provoca hipersensibilidad dentaria, fracturas de esmalte bajo fuerzas normales y favorece el desarrollo y avance de lesiones de caries. El objetivo de este estudio fue establecer si existen diferencias significativas en los índices COPD/ceod entre escolares de 6 a 12 años con presencia de HIM y escolares sin HIM de la provincia de Santiago. Material y métodos: Este estudio observacional, descriptivo y de corte transversal fue realizado en 1270 escolares de 6 a 12 años de la provincia de Santiago, seleccionados aleatoriamente y estratificados por nivel socioeconómico cuyos padres aceptaron su participación mediante consentimiento informado. Los escolares fueron evaluados por dos examinadores calibrados que utilizaron los criterios diagnósticos de la Academia Europea de Odontología Pediátrica (EAPD) para la detección de HIM y los criterios de la OMS para determinar historia de lesiones de caries a través de índice COPD/ceod. Los datos fueron consignados en un formulario diseñado para esta investigación y analizados mediante la Prueba Z y la Prueba de Mann-Whitney (considerando p<0,05) Resultados: La prevalencia de HIM fue de 12,8%. El COPD/ceod en escolares con HIM fue 1,00 y 1,88 respectivamente y en escolares sin HIM 0,43 y 1,65 respectivamente. La diferencia entre ambos grupos fue significativa sólo para COPD (p=0,000). Los componentes del COPD en pacientes con HIM fueron C=0,32; O=0,64 y P=0,04 y en grupo control C=0,13; O=0,29 y P=0,01. En los tres casos se encontró diferencia significativa (p<0,001; p<0,001 y p=0,003). Conclusión: Escolares de 6 a 12 años de la provincia de Santiago afectados con HIM presentan mayor COPD, independientemente del sexo y el estrato socioeconómico que escolares sin HIM.

Trabajo de Investigación Requisito para optar al Título de Cirujano Dentista
Introducción: La Fluorosis Dental ha ido en aumento en Chile como a nivel mundial, asociado a la utilización de fluoruros como principal estrategia para la prevención y control de la caries dental. El objetivo fue determinar la prevalencia y severidad de Fluorosis Dental en niños de 6 a 12 años de edad de la Provincia de Santiago. Materiales y métodos: Corresponde a un estudio observacional, transversal y descriptivo, en el cual se evaluaron 1270 niños de 6 a 12 años de edad de distinto estrato socioeconómico de 7 colegios de la Provincia de Santiago. Se realizó el examen clínico intraoral por dos examinadores previamente calibrados, registrando presencia o ausencia de Fluorosis y su grado de severidad aplicando el Índice de Thylstrup y Fejerskov, basado en 10 parámetros clínicos. Se determinó la distribución de Fluorosis según sexo, edad y estrato socioeconómico. Los datos fueron analizados por el programa SSPS y test de Chi-cuadrado con un valor de significancia estadística del 95% (p=0,05) Resultados: La prevalencia de Fluorosis Dental fue 53,9% (n=684). De los individuos que presentaron Fluorosis el 41,1% correspondió al grado 1, el 35,2% al grado 2, el 20,3% al grado 3 y el 3,4% a los grados 4,5 y 6. La distribución por sexo fue 56,5% en mujeres y 51,1% en hombres, no encontrándose diferencia significativa entre ambos sexos (p=0,05). Se observó la menor prevalencia de Fluorosis a los 6 años con 45,7% y la mayor a los 12 años con 62% no observándose diferencia significativa por edad (p=0,091). La prevalencia en el estrato socioeconómico I fue 41,9%, en el estrato II 53,5% y en el estrato III 63,8% existiendo diferencia significativa (p=0,00). Conclusión: La prevalencia de Fluorosis Dental en niños de 6 a 12 años de edad de la Provincia de Santiago es 53,9% predominando en quiénes presentaron la condición los grados de severidad 1, 2 y 3 del Índice TF con 96,6%. Se encontró relación estadísticamente significativa entre el estrato socioeconómico y prevalencia de Fluorosis, predominando en el estrato socioeconómico III. No se encontró relación estadísticamente significativa de presencia de Fluorosis con el sexo ni la edad.

Resumo: Nas últimas décadas ocorreu um dec1ínio na prevalência de cárie na maioria dos países desenvolvidos e em desenvolvimento e um concomitante aumento na prevalência da fluorose dental. Assim o desenvolvimento de um dentiftício para crianças, com concentração reduzida de flúor poderia proporcionar maior segurança em relação a fluorose dental, desde que provasse ser tão eficiente quanto um dentiftício convencional. A avaliação in vitro demonstrou que a reatividade de uma formulação contendo 550 ppm F foi melhorada, aumentando a incorporação de flúor no esmalte dental bovino com desempenho similar a um dentiftício convencional com 1100 ppm F. Resultados preliminares sobre esta formulação, com o uso de placas palatinas, demonstraram sua eficácia em reduzir a desmineralização do esmalte. Entretanto não foi avaliada a relação dose/efeito, como também não foi utilizado como controle um dentiftício "Gold Standard" para demonstrar equivalência de efeito. Para avaliação do dentiftício foi realizado um estudo cruzado, duplo-cego, composto de 5 etapas, onde 15 voluntários adultos, usando prótese parcial removível, contendo 4 blocos de esmalte bovino, sendo 2 hígidos e 2 com lesão artificial subsuperficial de cárie. Os voluntários foram submetidos aos seguintes tratamentos com dentiftícios: 1= Não Fluoretado; 11= 275 ppm F; III=550 ppm F; IV= 1100 ppm F; V= Crest ("Gold Standard" ) 1100 ppm F. Os dentiftícios experimentaís são a base de sílica e foram formuladas com pH 5,5 para melhorar a reatividade do flúor (NaF) com o esmalte dental. Análises da dureza (Knoop) do esmalte superficial e seccionado longitudinalmente foram determinadas nos blocos. O esmalte também foi submetido a analises para avaliação do flúor incorporado. Os resultados demonstram que a formulação com 550 ppm F foi mais eficiente que os dentiftícios placebo e 275 ppm F (pO,O5) em: 1) Reduzir a desmineralização do esmalte na superfície e na lesão de cárie; 2) Potencializar a remineralização do esmalte na superfície e na lesão de cárie; 3) Aumentar o flúor incorporado no esmalte hígido e com lesão de cárie. Os resultados sugerem que a formulação experimental com concentração reduzida de flúor pode ter a mesma eficácia do dentiftício convencional e poderia ser mais segura em relação a fluorose dental
Abstract: In the last decades there was a caries decline in most of the countries of the world, but at the same time the prevalence of dental fluorosis increased. Thus, the development of a dentifrice for children with low fluoride concentration would offer higher safety with regard to dental fluorosis, as long as it prove to be as efficient as a conventional one with 1000-1100 ppm F. The in vitro evaluation showed that the reactivity of a formulation containing 550 ppm F was improved, increasing the fluoride incorporation in dental enamel with action similar to a conventional dentifrice with 1100 ppm F. Preliminary results of this formulation, using palatal appliances, showed its efficiency on reducing enamel demineralization. Nevertheless, the dose/effect relationship was not evaluated, as well as a control such as a Gold Standard dentifrice was not used to demonstrate equivalence of effect. A 5 step double-blind crossover study was conducted with 15 adult volunteers wearing removable prosthesis, containing 4 bovine enamel blocks, 2 sound and 2 with subsuperficial caries lesions. The volunteers were submitted to the following treatments with dentifrices: 1= Non-fluoridated; II=275 ppm F; III=550 ppm F; IV= 1100 ppm F; V= Crest ("Gold Standard", 1100 ppm F). The dentifrices were silica-based and the formulations were modified (PH5,5) to improve the reactivity of fluoride (NaF) with dental enamel. Surface and cross sectional enamel microhardness (Knoop) were determined in the blocks. Enamel was also analyzed to evaluate fluoride uptake. The data showed that the formulation with 550 ppm F was more efficient than placebo and the one with 275 ppm F (p<0.05) and it was equivalent to the "gold standard"(p>0,05) in: 1) Reducing enamel demineralization on surface and in caries lesion; 2) Enhancing enamel remineralization on surface and in caries lesion; 3) Increasing fluoride in sound and carious enamel. The data suggest that the experimental formulation with lower fluoride concentration could have the same anticaries efficiency as the conventional and would be more safe with respect to dental fluorosis

Abstract:
The North central province plays the main agricultural role in Sri Lanka as a developing agricultural-based economy country in the world. Excessive amount of nitrate and fluoride in groundwater consumption is becoming a crucial issue on human health in Sri Lanka, especially in the North Central part of the country. Dental fluorosis and skeleton fluorosis are the major health impacts based on an excessive amount of fluoride as well as presumption on causing chronic kidney disease (CKD). Nitrogenous compounds in groundwater for drinking have been considered possible risk factors for oesophageal cancer and haemoglobinemia or blue baby syndrome. Human activities and natural processes have polluted groundwater. Having a lack of understanding of the actual need for fertilizer, farmers usually tend to apply the surplus amount, thus increasing nitrogen pollution. Accordingly, this research was conducted to deepen the understanding of the distribution of fluoride and nitrate in groundwater in the Anuradhapura area in terms of geological and anthropogenic influences on groundwater quality. Well water samples were collected from intensive agricultural activity areas in Anuradhapura. Physical and chemical parameters were analyzed to identify whether the higher nitrate and fluoride or any compound of a mixture of heavy metals such as cadmium and/ or arsenic is the actual cause for kidney and other health-related issues among the community. Water samples' pHs were in the range of 6.7-7.7. All the wells can be categorized as low salinity water. Turbidity average of 3.51 NTU range of 1-8 NTU was found to be mainly contributed by nitrate at the average of 28.725 mg/L and ranged from (22-131) mg/L of nitrate. In addition, fluorite was found high in Anuradhapura with an average of 0.6 mg/L and ranged from (0.4 - 1.7) mg/L. Sulphate level was also high with an average of 178mg/L and ranged from (58-505 mg/L). There was no significant effect of heavy metals such as cadmium, arsenic, iron, and copper concentrations which were below the permissible level of 0.01mg/L. The research clearly indicates the abundance of nitrate and fluoride in groundwater, especially in the dry zone. The major sources are fluoride-bearing minerals in bedrock and soil zone. In addition to that, the influence of agriculture which causes excessive nitrate levels in groundwater, is apparent, irrespective of climatic zones.
