Full textObjectives As the outer cover of teeth structure, enamel is the hardest, stiffest and one of the most durable load-bearing tissues of the human body. Also, enamel is an elegantly designed natural biocomposite. From a material science point of view, scientists are interested in the structure and function of the nature material. How does nature design the material to meet its functional needs? From a dental clinic point of view, dental practitioners are keen to know the properties of enamel and compare it with different dental materials. What kind of dental materials can best simulate enamel as a restoration in the oral cavity? The research presented in this thesis on the mechanical behaviour of enamel in respect of its structural and compositional characteristics will attempt to provide answers or indications to the above questions. Theoretical analysis, as well as experimental investigations of both man-made and natural composites materials, has shown that hierarchical microstructure and organic matrix glues the inorganic particles together and plays an important role in regulating the mechanical properties of the composite. Bearing this finding in mind, in the current investigations, we assume the hierarchical microstructure and trace protein remnants in enamel regulate the mechanical behaviour of the natural biocomposite to meet its functional needs as a load bearing tissue with superb anti-fatigue and wear resistant properties. One of the important reasons that dental hard tissues haven’t been thoroughly investigated is due to the limited sample volume. Fortunately, with the development of nanoindentation technique and equipment, it is now possible to explore the mechanical properties of small volume samples. The application of nanoindentation on dental hard tissues has been documented. However, most investigations have concentrated on only reporting the basic mechanical properties such as elastic modulus and hardness. Very few of them have taken the role of microstructure and composition of these natural biocomposites into their considerations. The main aim of this investigation is to interpret how microstructural and compositional features of enamel regulate its mechanical behaviour. To achieve this goal, the analytical methods considering nanoindentation data need to be expanded so that more information not only elastic modulus and hardness but also stress-strain relationship, energy absorption ability, and creep behaviour may be evaluated with this technique. These new methods will also be of benefit to dental material evaluation and selection. Materials and methods Based on the Oliver-Pharr method1 for the analysis of nanoindentation data, Hertzian contact theory2 and Tabor’s theory3, a spherical nanoindentation method for measuring the stress-strain relationship was developed. Furthermore, nanoindentation energy absorption analysis method and nanoindentation creep test were developed to measure the inelastic property of enamel. With the above methods, sound enamel samples were investigated and compared with various dental materials, including dental ceramics and dental alloys. • Firstly, using a Berkovich indenter and three spherical indenters with 5, 10 and 20 µm nominal radius, the elastic modulus, hardness and stress-strain relationship of different samples were investigated and compared. • Secondly, mechanical properties of enamel in respect to its microstructure were investigated intensively using different indenters by sectioning teeth at different angles. • Thirdly, inelastic behaviour of enamel such as energy absorption and creep deformation were observed and compared with a fully sintered dense hydroxyapatite (HAP) disk to illustrate the roles of protein remnants in regulating the mechanical behaviour of enamel. • Fourthly, to confirm the functions of protein remnants in controlling mechanical behaviour of enamel, enamel samples were treated under different environments such as burning (300°C exposure for 5 min), alcohol dehydration and rehydration to change the properties of proteins before the nanoindentation tests. • Lastly, micro-Raman spectroscopy was employed to measure and compare the indentation residual stresses in enamel and HAP disk to evaluate the role of both hierarchical microstructure and protein remnants in redistributing the stresses and reinforcing the mechanical response of enamel to deformation. Results and significance Nanoindentation is an attractive method for measuring the mechanical behaviour of small specimen volumes. Using this technique, the mechanical properties of enamel were investigated at different orientations and compared with dental restorative materials. From the present study, the following results were found and conclusions were drawn. Although some newly developed dental ceramics have similar elastic modulus to enamel, the hardness of these ceramic products is still much higher than enamel; in contrast, despite the higher elastic modulus, dental metallic alloys have very similar hardness as enamel. Furthermore, enamel has similar stress-strain relationships and creep behaviour to that of dental metallic alloys. SEM also showed enamel has an inelastic deformation pattern around indentation impressions. All of these responses indicated that enamel behaves more like a metallic material rather than a ceramic. Elastic modulus of enamel is influenced by highly oriented rod units and HAP crystallites. As a result, it was found to be a function of contact area. This provides a basis to understand the different results reported in the literature from macro-scale and micro-scale tests. Anisotropic properties of enamel, which arise from the rod units, are well reflected in the stress-strain curves. The top surface (perpendicular to the rod axis) is stiffer and has higher stress-strain response than an adjacent cross section surface because of the greater influence of the prism sheaths in the latter behaviour. Enamel showed much higher energy absorption capacity and considerably more creep deformation behaviour than HAP, a ceramic material with similar mineral composition. This is argued to be due to the existence of minor protein remnants in enamel. Possible mechanisms include fluid flow within the sheath structure, protein “sacrificial bond” theory, and nano-scale friction within sheaths associated with the degustation of enamel rods. A simple model with respect of hierarchical microstructure of enamel was developed to illustrate the structural related contact deformation mechanisms of human enamel. Within the contact indentation area, thin protein layers between HAP crystallites bear most of the deformation in the form of shear strain, which is approximately 16 times bigger than contact strain in the case of a Vickers indenter. By replotting energy absorption against mean strain value of a protein layer, data from different indenters on enamel superimposed, validating the model. This model partially explained the non-linear indentation stress-strain relationship, inelastic contact response and large energy absorption ability of enamel and indicated the inelastic characteristics of enamel were related to the thin protein layers between crystallites. Following different treatments, mechanical properties of enamel changed significantly. By denaturing or destroying the protein remnants, mechanical behaviour, especially inelastic abilities of enamel decreased dramatically, which indicates matrix proteins endow enamel better performance as a load bearing calcified tissue. Comparison of Raman derived residual maps about indentations in enamel and a sintered homogeneous HAP showed the hierarchical structure influenced the residual stress distribution within enamel. Moreover, less residual stresses were found in enamel and were a consequence of the protein remnants. These are evidence as to how the microstructure meets the functional needs of the enamel tissue. In general, evidence from different approaches indicated that the hierarchical microstructure and small protein remnants regulated the mechanical behaviour of enamel significantly at various hierarchical levels utilising different mechanisms. This investigation has provided some basis for understanding natural biocomposites and assisting with dental clinic materials selection and treatment evaluation procedures. References 1.

Resumo: Este estudo avaliou o comportamento mecânico de tecidos dentários de pacientes com câncer de cabeça e pescoço submetidos à radioterapia. No capítulo I, o ensaio mecânico da nanoindentação foi utilizado para determinar a dureza e módulo de elasticidade do esmalte, dentina e da região de união restauradora em dentina (adesivo, camada híbrida e dentina subjacente). Foram utilizados seis dentes incisivos inferiores irradiados in vivo e não irradiados (grupos controle). A dureza e o módulo de elasticidade e foram obtidos após a realização da nanoindentação com pico de força de 1000 µN em dentina intertubular e região de união restauradora e 1500 µN em esmalte (centro do prisma) usando o microscópio de força atômica equipado com nanoidentador com tempo 5-2-5 seg para carregamento, aplicação e descarregamento da carga. A análise de variância a um fator foi aplicada com nível de significância de 0.05%. O valor da nanodureza e módulo de elasticidade não foram estatisticamente diferentes entre os tecidos avaliados em ambos os grupos irradiados e controle. Desta foma, pode-se concluir que tanto a dureza como o módulo de elasticidade de dentes submetidos à radioterapia in vivo não apresentam alterações das propriedades mecânicas no esmalte, dentina e região de união adesivo/dentina devido á ação direta da radioterapia. No capítulo II, foram avaliadas as propriedades viscoelásticas (storage e loss modulus) de três regiões diferentes: esmalte, junção amelo-dentinária (JAD) e dentina de dentes irradiados in vivo. Cinco dentes não irradiados (grupo de controle, n = 5) e cinco dentes irradiados in vivo (grupo irradiado, n = 5) foram utilizados para produzir cinco fatias de cada para avaliar a três áreas distintas: o esmalte, o JAD , e a dentina. A análise por mapeamento (Modulus Mapping Analysis) foi escolhida para avaliar a perda e armazenamento de energia mediante uma carga aplicada. Três regiões de dados foram coletados de cada área de tecido de cada fatia, totalizando quinze mapeamentos por tecido por grupo. Os valores do módulo foram calculados pelo software Hysitron® e a análise da variância (ANOVA Plot Split) e teste de Tukey a 5% de significância foram utilizados para comparar os grupos e tecidos. As três áreas avaliadas de ambos os grupos controle e irradiado revelaram diferença estatística no módulo de perda e armazenamento. Ambos os valores de perda e de armazenamento apresentaram-se maiores no grupo irradiado para esmalte (164,44 ± 36,60 GPa; 177,59 ± 58,84 GPa), JAD (50,85 ± 35,78 GPa; 83,33 ± 38,59 GPa) e dentina (21,18 ± 18,61 GPa; 52,44 ± 26,56 GPa) do que no grupo controle para o esmalte (127,15 ± 74,45 GPa; 162,85 ± 74,63 GPa), JAD (25,72 ± 9,64 GPa; 21,93 ± 52,78 GPa) e dentina (10,39 ± 8,65 GPa; 32,10 ± 20,39 GPa), respectivamente. Foi possível concluir neste estudo, que as propriedades viscoelásticas dos dentes irradiados in vivo apresentam-se diferentes das do grupo controle. Estes resultados sugerem que, após a radioterapia, os tecidos dentais estariam mais suscetíveis a fraturas
Abstract: This study evaluated the mechanic properties of enamel, dentin, and dentin bond interface of patients who undergone head and neck cancer treatment. On I chapter, the nanoindentation technique was used to determine the hardness (H) and reduced modulus of elasticity (Er) of the control group on enamel, dentin, and dentin bond interface (adhesive layer, hybrid layer and underlyer dentin). The Er and H were obtained after completion of nanoindentation with peak force of 1000 µN on intertubular dentin and restorative dentin interfaces and 1500 µN on enamel (prism center) using the atomic force microscope with nanoindenter accopled with test time 5-2-5 seconds for loading, holding and unloading. The one-way analysis of variance (p'< ou ='0.05) was applied and the valus for H and Er for both groups and tissues were no statistical different. As conclusion, the nanohardeness and elastic modulus behavior of the enamel, dentin and dentin bond interface was not impacted by the radiotherapy treatment of head and neck cancer. On II chapter, the viscoelastic properties were assessed (storage and loss modulus) of three different regions: enamel, dentin-enamel junction (DEJ) and dentin irradiated teeth in vivo. Five non irradiated teeth (control group, n=5) and five in vivo irradiated teeth (irradiated group, n=5) were used to produce five beams that were used to evaluate three different areas: the enamel, the DEJ, and the dentin. Perpendicular sections to the long axis of the teeth were made at middle region of the crown to produce the beams. The Modulus Mapping Analysis was chosen to evaluate the loss and storage moduli of each area. Three data regions were collected of each tissue area of each beam, summing a total of fifteen data per tissue per group. The modulus values were calculated by the Hysitron® software and an Analysis of Variance (ANOVA Split Plot) and Tukey test at 5% of significance was used to compare groups and tissues. All the three areas evaluated of control and irradiated group revealed statistical difference on the Loss and Storage Moduli. Both the loss and storage values are higer on the irradiated group for enamel (164.44±36.60 GPa; 177.59±58.84 GPa), DEJ (50.85±35.78 GPa; 83,33±38,59 GPa) and dentin (21.18±18.61 GPa; 52.44±26.56 GPa) than control group values for enamel (127.15±74.45 GPa; 162.85±74.63 GPa), DEJ (25.72±9.64 GPa; 21.93±52.78 GPa) and dentin (10.39±8.65 GPa;32,10±20,39 GPa), respectivally. The viscoelastic properties of in vivo irradiated teeth are different from control group. The enamel, DEJ and dentin presented the higer values on the in vivo irradiated group. These finds suggest that after radiotherapy, the dental tissues are more susceptible to fractures

Full textPURPOSE: To assess the influence of simulated oral erosive/abrasive challenges on the bond strength of an etch-and-rinse two-step bonding system to enamel using an in situ/ex vivo protocol. METHODS: Bovine enamel blocks were prepared and randomly assigned to four groups: CONT - control (no challenge), ABR - 3x/day-1 minute toothbrushing; ERO - 3x/day - 5 minutes extraoral immersion into regular Coca Cola; and ERO+ABR - erosive protocol followed by a 1-minute toothbrushing. Eight blocks were placed into an acrylic palatal appliance for each volunteer (n = 13), who wore the appliance for 5 days. Two blocks were subjected to each of the four challenges. Subsequently, all the blocks were washed with tap water and Adper Single Bond 2/Filtek Z350 were placed. After 24 hours, 1 mm2 beams were obtained from each block to be tested with the microtensile bond strength test (50 N load at 0.5 mm/minute). The data were statistically analyzed by one-way RM-ANOVA and Tukey's tests (alpha = 0.05). RESULTS: No difference was detected among the ABR, ERO, and CONT groups (P > 0.05). ERO+ABR group yielded lower bond strengths than either the ABR and ERO groups (P < 0.0113).
