“…The great variation in the amount of fluoride observed in sound dentin among the samples has also been noted by others. However, the concentration of fluoride observed in the present study was higher than that in other studies done in the 1970s (7)(8)15), perhaps due to the increased availability of fluoride. Furthermore, our samples were obtained from an area with a fluoridated water supply where there was access to fluoride dentifrice, whereas the samples used in other studies (7)(8)15) were collected from non-fluoridated areas where access to fluoride dentifrice was probably limited.…”

“…Calcium, inorganic phosphate and fluoride are the main constituents of the mineral phase of dentin (2,(7)(8)(9). The concentrations of these ions play an important role in the processes of demineralization and remineralization of dentin (3)(4)(10)(11)(12).…”

“…Previous studies of the inorganic phosphate and calcium contents of dentin have involved biochemical analyses (10,13). More recently, however, different methodologies such as energy-dispersive X-ray analysis (2,4,(13)(14), neutron activation analysis (15,16), atomic absorption (7)(8) and laser (17)(18) spectrometry have been employed. Biochemical analysis is able to detect small amounts of Ca, P i and F, and has been widely used in studies of biofilm, dental enamel and biofilm fluid (19)(20)(21)(22)(23)(24).…”

The aim of this study was to evaluate the concentrations of calcium (Ca), inorganic phosphate (P i ) and fluoride (F) in carious dentin and in different layers of sound dentin. The samples examined were 52 permanent teeth (26 sound and 26 carious), which were subjected to two experiments to assess the mineral content of: 1) two layers (internal and external) of sound dentin and 2) sound and carious dentin. Ca and P i were analyzed using a colorimetric method with arsenazo III (C22H18As2N4O14S2) and molybdate reagents, and F was analyzed using a specific electrode. A non-parametric test, the MannWhitney test, was used to verify differences between groups. Sound dentin showed a higher concentration of fluoride in the internal layer than in the external layer (P = 0.03), but no inter-layer differences in Ca or P i concentration were evident. Lower concentrations of Ca, P i and F were observed in carious dentin than in sound dentin (P < 0.05). The results of this study suggest that the internal layer of sound dentin has a higher fluoride content than the external layer, and that carious dentin has lower concentrations of Ca, P i and F than sound dentin.

“…In this context, Derise et al (1974) reported that the mean concentration of Ca and P were 37.1 and 18.1% in the permanent teeth enamel, while Lakoma and Rytomaa (1977) did not observed differences in the amount of theses ions between primary and permanent teeth enamel. The different values of Ca and P reported in the current study may be due to factors such as the region where the teeth were collected, variations between individual teeth, the type, age and ethnicity and even the methodology performed at the researches.…”

“…Em nosso estudo encontramos os valores médios dos elementos quími-cos da dentina em que o cálcio correspondeu a 34,29% e o fósforo a 20,42% (Quadro 3) O valor médio de porcentagem observado em estudos da dentina de dentes permanentes humanos foi entre 26,7% e 50,77 para cálcio e 13,6% a 18,2% para o fósforo (Derise 1974, Oliveira et al 2010. Diante disso, observamos mais uma vez similaridade de nossos resultados com os valores descritos na literatura para dentes humanos.…”

Pesq. Vet. Bras. 34(8):791-796, agosto 2014 791 RESUMO.-O objetivo desse trabalho foi contribuir com o estudo anatômico, morfométrico, ultraestrutural e propriedades físicas dos dentes permanentes do primata Sapajus apella. Para tal, foram utilizados 10 animais adultos e machos. Os dentes foram avaliados quanto ao seu comprimento e quanto à anatomia radicular externa e interna considerando número de raízes e canais, forma e direção radicular e forma do canal, assim como análise da densidade e diâmetro tubular do canal radicular, composição e microdureza dentinária. A anatomia radicular desse primata apresentou especificidades, como o número de raízes do segundo pré-molar superior e a presença do terceiro pré--molar. Quanto à densidade e o diâmetro dos túbulos dentinários, observou-se uma diminuição do número e diâmetro de túbulos ao longo do canal radicular, havendo diferença estatisticamente significante ao se comparar o terço apical com as regiões cervical e média, padrão de densidade e tamanho semelhantes a dentes humanos. Semelhanças também foram encontradas com dentes humanos quando comparados os valores de microdureza e proporção de elementos químicos encontrados na dentina radicular. Brazil. E-mail: rafalima@ufpa.br This paper aimed the anatomical study including morphometric, ultrastructural and physical properties of permanent teeth of Sapajus apella primate. Ten adult male monkeys were studied. The teeth were evaluated for their length, root anatomy (external and internal considering the number of roots and canals), direction and shape of the root canal, density and diameter of the tubular root canal, dentin microhardness, and composition. The root anatomy showed specificity regarding the number of roots of the second premolar and the presence of the third premolar. We observed a decrease in the number and diameter of dentinal tubules along the root canal, a statistically significant difference when compared with the apical and cervical regions. Similarities with human teeth were found in regard to microhardness values and proportion of chemical elements in the root dentin.
