Filter by:The aim of this randomized, controlled, prospective clinical trial is to evaluate the performances of two different universal adhesives and an etch&rinse adhesive in restoration of non-caries cervical lesions. Twenty patients will receive restorations. Lesions will be divided into 7 groups according to adhesive systems and application modes: GSE: Gluma Universal- self etch, GSL: Gluma Universal-selective etching, GER: Gluma Universal-etch&rinse, ASE: All Bond Universal- self etch, ASL: All Bond Universal- selective etching, AER: All Bond Universal- etch&rinse, SB (Control): Single Bond2+etch&rinse. Restorations (nano-hybrid composite) will be scored with regard to retention, marginal discoloration, marginal adaptation, recurrent caries and post operative sensitivity using modified USPHS criteria after 48 months. Two examiners who is not involved in the placement of restorations will conduct the evaluations. Descriptive statistics will be performed using Chi-square tests.
To evaluate the change in patient Oral Health-related Quality of Life (OHRQoL) from wearing a cobalt chrome (CoCr) removable partial denture (RPD) to wearing the Solvay Dental 360TM polymer Removable Partial Denture (RPD) for 8 weeks.
This study compares the associated risk factors between adults with tooth wear and age- and sex-matched controls without tooth wear.
The clinical study was a single-blind, randomised intervention study to measure surface changes of polished and unpolished enamel in situ following an orange juice acid challenge. Ethical approval for the study was granted by the Stanmore Health Research Authority REC ref 15/LO/0417, and the study was conducted per the guidelines for Good Clinical Practice. The study investigated a total 6 erosion regimes divided in 3 different erosion times plus ex vivo immersion in orange juice drink versus in vivo rinsing of the same orange juice drink.
This study evaluates the effect of coatings on bacterial adhesion on denture acrylic and the wear of denture teeth.
The aim of this research is to investigate the impact of dietary advice on the progression of tooth wear over 6 months using a randomised clinical trial design. Participants with severe tooth wear will be recruited. Half of those patients will receive a detailed dietary advice and the other half will be receive standard of care dietary advice. Moulds will be made of their mouths at the original appointment and 6 months later. These moulds will be scanned and superimposed to see if there is any difference in their level of tooth wear
This is a questionnaire based study investigating the relationship between the timing of dietary acid intake toothbrushing and erosive tooth wear. Data will be collected on the timing, nature, frequency and duration of dietary acid intakes and timing and frequency of the participants toothbrushing. Signs of the participants erosive tooth wear will then be recorded
Clinical trials of bite splint use and night time tooth grinding have not been performed. Consequently, there are no definitive outcome measures or efficacy standards that can be applied to large clinical trials. The present preliminary trial will determine what objective measures can be used to evaluate efficacy. The outcome variables will fall into four categories: (1) fabrication efficacy, (2) compliance, (3) functional efficacy, and (4) user satisfaction. The immediate goals will: (1) focus on the over-the counter SOVA night guard, (2) conduct tests under controlled clinical conditions using the 'gold standard', the acrylic 'bite splint' or 'orthotic', hereafter called the "Michigan bite splint", to compare the performance and efficacy of the SOVA night guard. Subsequent studies will be able to use the outcome variables identified in this study for broader clinical trials. Specific Aim 1. To compare the SOVA night guard to the custom-acrylic Michigan bite splint in clinical laboratory conditions. Hypothesis: There will be no significant differences between the devices in terms of fabrication efficacy, functional efficacy or user satisfaction. Specific Aim 2. To compare the SOVA night guard to the custom-acrylic Michigan bite splint under ecologically relevant conditions, i.e., the home environment. Hypothesis: There will be no significant differences between the devices in terms of compliance or functional efficacy.
1. To characterize the microstructure (fracture toughness, particle size of ceramic, and inter-particle spacing) of three ceramic materials 2. To test the hypothesis that lower fracture toughness of glass and/or crystal phase in ceramics reduce wear damage of enamel. 3. To test the hypothesis that smaller sized crystals reduce wear damage of enamel. 4. To test the hypothesis that larger inter-particle spacing reduces wear damage of enamel. 5. To test the hypothesis that equivalent wear patterns exist in all directions between enamel versus enamel and ceramic versus enamel. 6. To test the hypothesis that bite force does not correlate with wear rates. 7. To test the hypothesis that salivary flow does not correlate with wear rates. 8. To test the hypothesis that a greater amount of wear is not associated with a loss in vertical dimension of occlusion. 9. To test the hypothesis that a greater amount of wear does not correlate with secondary cementum deposition as part of the passive eruption process. 10. To test the hypothesis that maximum wear occurs early and wear rates level off within the first two years. 11. To test the hypothesis that in vitro wear analysis does not correlate with in vivo wear measurements
