Annotation:
Systematic research on dental materials began after World War I. For a long time the research was focused on the physical properties of the materials, and papers dealing with biological aspects were scarce. By the late 1950s a growing interest in biological responses to dental materials developed, and from the 1970s biological and physical evaluations were deemed equally important (1). Mammalian cells have been maintained in vitro since the early years of this century, but the use of cultured cells to evaluate the effects of chemicals and drugs is a more recent occurrence. The first practical application of this technique was in pharmacological investigations (2), but applications in other fields soon followed, and in 1955 the first studies were reported where a cell culture technique had been applied to the biological evaluation of dental materials (3,4). Since then the use of cell culture systems in dental materials research has grown rapidly. The main application has been for the assessment of cytotoxic effects, and the purpose of this paper is to review different test methods and discuss some facets of the problems posed by the cytotoxicity testing of dental materials.

Annotation:
Evaluation of side-effects to low-dose exposure of any agent is difficult, especially if the agent exhibits a low toxicity. The most common way to approach such evaluation is to define special groups which are exposed more than others. Studies of such risk groups may facilitate interpretation of information related to those exposed to a low dose. For dental materials, dentists, dental assistants, and laboratory technicians represent typical risk groups. In addition to receiving dental treatments and having restorations like anyone else, they handle the materials in their daily work. The exposure to the materials occurs more frequently and at a higher dose for these groups than for the patient receiving dental treatment. Thus, the possibilities for side-effects are greater. Some materials are handled more closely by laboratory technicians than by other members of the dental team, e.g., dental ceramics.

In this thesis, four experimental studies are reported. Two concern the surface structure of commercially relevant dental implant materials. Characterisation of four treated substrates supplied by Straumann AG was carried out. These include substrates equivalent to the commercially available SLA, SLActive and Roxolid implants. The materials vary in substrate alloy, commercially pure (grade 2) Ti and a TiZr alloy, and surface preparation treatments. All substrates are sandblasted and acid etched however post-etching one set are stored in air whilst the others are stored in saline. Within the work both substrate composition and surface treatment is shown to impact on the respective surface oxide thickness, crystallinity and morphology. The other two experimental studies concern calcium phosphate deposition from solution onto substrates. The first investigation is the deposition of calcium phosphate from a simulated body fluid onto implant-like substrates, shown to be structurally equivalent to the SLA and SLActive implant surfaces. The effect of surface modifications on calcium phosphate deposition is investigated; over the period investigated calcium phosphate did not deposit onto the SLA substrate, whilst deposition occurred within 3 days on the SLActive substrate. The role of Mg2+ ions in the simulated body fluid is also investigated, with increased [Mg2+] resulting in a longer induction period and modified crystallinity of the hydroxyapatite film formed. The final study is a model study of the initial calcium phosphate deposition on to substrates. TiO2 rutile (110) and Al2O3 corundum (0001) were prepared to be atomically flat and then exposed to a simple calcium phosphate solution. Changes in surface structure and surface chemistry over the first three hours of exposure were investigated. Deposition occurred rapidly on both substrates with a complete surface coverage after 3 hours.

One of the fields of active research in dentistry today is biomaterials replacing, which is expected to be increasingly more similar to human dental enamel. As these dental materials are exposed to the diverse degrading actions present in the oral environment, it is important to know its superficial topography, which is related to the existence of asperities on a smaller scale, responsible for the interaction between opposing bodies. In this work we try to characterize the superficial topography of the dental enamel and evaluating a sane tooth and another degraded by use, comparing the values of the texture SEM. The results indicate that the dental enamel presents a topographical profile with a symmetrical distribution, between peaks and valleys, relative to the parameters of amplitudes as well as to parameters of material concentrations. The values encountered for the amplitude and densities of peaks parameters are high. It was verified in the degraded tooth the existence of mechanisms of mechanical origin added to chemical reactions, producing a wear type called “chemical wear”. The existence of this phenomenon was identified by verification in the degraded tooth of the presence of more deep valleys in relation to the peaks. The abrasion mechanism, also present in this wear type, decreased significantly the amplitude of the peaks. The evaluation methodology via profilometry3D revealed potentially efficient for the characterization of superficial topography and by verification of the mechanisms of wear dental.

Partial and total edentation has been a real problem worldwide and at all times. The realization of an individualized treatment plan for each form of edentation takes into account the particularities of the edentulous prosthetic field and the materials used as well as the conventional or modern techniques applied. The study group consisted of 220 patients in whom dental implants were inserted; the control group was randomized from 10 patients with a favorable evolution out of the 210 (94.55%). At 7 and 60 days after the insertion of the dental implants and 6 months after their prosthetic loading, crevicular fluid and peri-implant fluid was harvested, for the quantitative determination of Osteoprotegerin (OPG) and Interleukin 1β (IL1-β). Of the 220 patients studied, 10 developed peri implantitis (5.45%) as follows: 4 patients with mucositis and 6 patients with severe form. The results obtained show that there are differences with statistical significance between the OPG values obtained in crevicular fluid in healthy compared to patients with mucositis after 7 days (p <0.001). Regarding IL1-β, there are differences with high statistical significance between the levels in healthy patients and those with peri-implantitis after 7 days (p <0.001). Our results show the existence of a high correlation between the clinical status and these two parameters, especially after the determinations performed at 7 and 60 days. In conclusions, the present study shows that the OPG and IL1-β can be considered useful markers in the evaluation of the patient after the insertion of the dental implant and after its prosthetic loading.

For the better part of the past 15 years composite materials have been used to repair corrosion in high pressure gas and liquid transmission pipelines. This method of repair is widely accepted throughout the pipeline industry because of the extensive evaluation efforts performed by composite repair manufacturers, operators, and research organizations. Pipeline damage comes in different forms, one of which involves dents that include plain dents, dents in girth welds and dents in seam welds. An extensive study has been performed over the past several years involving multiple composite manufacturers who installed their repair systems on the above mentioned dent types. The primary focus of the current study was to evaluate the level of reinforcement provided by composite materials in repairing dented pipelines. The test samples were pressure cycled to failure to determine the level of life extension provided by the composite materials relative to a set of unrepaired test samples. Several of the repaired dents in the study did not fail even after 250,000 pressure cycles were applied at a range of 72% SMYS. The results of this study clearly demonstrate the significant potential that composite repair systems have, when properly designed and installed, to restore the integrity of damaged pipelines to ensure long-term service.
