Filter by:The aim of this study will be to evaluate the effect of reduced dentin etching time on the 6- and 12-months clinical performance of two universal adhesive systems used as etch-and-rinse application mode in non-carious cervical lesions (NCCLs). Materials & Methods: 140 restorations will be randomly placed in 35 subjects according to the following groups: SUP5 (Scotchbond Universal Plus adhesive on dentin etched for 5 seconds); SUP15 (Scotchbond Universal Plus adhesive on dentin etched for 15 seconds); GBU5 (Gluma Universal Bond adhesive on dentin etched for 5 seconds); GBU15 (Gluma Universal Bond adhesive on dentin etched for 15 seconds). All groups will be light-cured for 10s/1,000 mW/cm2. A resin composite will be placed by applying three increments and each one will be light cured for 20s/1,000 mW/cm2. The restorations will be finished immediately with fine diamond burs and polishers. The restorations will be evaluated at baseline and after 6- and 12-months by using the FDI criteria. The following outcomes will be evaluated: retention, marginal staining, marginal adaptation, post-operative sensitivity and recurrence of caries. The differences among the groups will be calculated using Friedman repeated measures analysis of variance rank (α = 0.05).
In the management of patients with noncarious cervical lesions (NCCL), we observe that they frequently present signs of anxiety, traumatic brushing, bruxism or eating disorders. These multifactorial and interrelated etiologies make diagnosis and management difficult. Furthermore, in the literature, there is a lack of studies that evaluate the relationship between these risk factors and NCCL. A better understanding of the etiology and risk factors would help to optimize patient management and direct patients to the most appropriate therapies.
The aim of this study is to describe the prevalence of non-carious cervical lesions in middle adulthood patients attending the Cairo University Dental Educational Hospital and to analyze the distribution of lesions by gender and age, tooth functional group, jaw, arch side and tooth surface. Moreover, to explore the associated risk indicators of the lesions as well as the quantity of saliva, as one of the potential etiological factors, will be assessed.
The overall objective of this clinical investigation is to evaluate the clinical safety and performance of the new flowable composite TM Flow for treatment of non-carious cervical lesions. Each participant receives two different fillings (test- and control material) in two different teeth. The fillings are assessed according to selected FDI criteria at baseline (7-10 days after filling placement) and after 1, 6, 12, 24, 36 and 60 months.
The aim of this study will be to evaluate the effect of prolonging solvent evaporation time on the 6- and 12-months clinical performance of two universal adhesive systems used as selective enamel etch (SEE). Methods: 140 restorations will be randomly placed in 35 subjects according to the following groups: SUP5 (Scotchbond Universal Plus evaporated for 5 s); SUP25 (Scotchbond Universal Plus evaporated for 25 s); GBU5 (Gluma Bond Universal evaporated for 5 s); GBU25 (Gluma Bond Universal evaporated for 25 s). Resin composite will be placed incrementally and light-cured. The restorations will be evaluated at baseline, after a week, 6 and 12 months using the FDI and USPHS criteria. Statistical analyses will be performed using appropriate tests (α = 0.05).
Cervical cancer screening is important as it enables identification of women at increased risk of the disease, but high-quality diagnostics of screen-positive women and effective treatment of those with precancer are critical in preventing progression to cancer. With the current transition from cytology-based to primary human papillomavirus (HPV)-screening and a growing proportion of HPV-vaccinated women, diagnostics of screen-positive women will become more challenging in the decades to come. Thus, there is a need to explore how to improve diagnostics while ensuring a low number of unnecessary procedures such as colposcopy and the collection of multiple cervical biopsies. The overall purpose is: - To investigate the diagnostic accuracy of cervical precancer when using a colposcopic scoring system in the diagnostic work-up of screen-positive women. - To investigate the performance of a colposcopic scoring system to identify women without cervical precancer in whom collection of biopsies can be safely omitted.
The goal of this observational study is to compare the accuracy and sensitivity of High-throughput human papilloma virus(HPV) typing and integrated assays with routine screening protocols (Cobas HPV test combined with thinprep cytologic test(TCT) for the detection of cervical intraepithelial neoplasia in the general and hospital populations. The main questions it aims to answer are: - High-throughput HPV typing and integrated assays can screen for ≥ cervical intraepithelial neoplasia (CIN2 or CIN3) with high sensitivity and accuracy. - High-throughput HPV typing and integrated assays can be promoted as a screening tool for cervical cancer. Participants will be screened with routine screening protocols (Cobas HPV test combined with TCT test), and if the results are abnormal, colposcopy and cervical biopsy will be performed.
The aim of the study was to assess the post-market performance and tolerability of Cerviron® ovules in the treatment and management of cervical lesions of different etiologies. The study included clinical data related to aspect of lesions performed during routine colposcopy exams, the degree of re-epithelialization of the cervical mucosa, vaginal pH, pain level, and vaginal bleeding level.
In restorative dentistry, to enhance bond strength between dentin and simplified adhesive systems, new materials or applications are constantly being developed all the time. In order to create a better hybrid layer quality, modifications are made to the chemical contents and application methods of the adhesives. For inhibition or slow down of collagen or resin matrix degradation at the adhesive interface, procedures like using protease enzyme inhibitors or additional hydrophobic layer applications are tested by in vitro and in vivo studies. The main goal of this double-blind randomized clinical trial is to evaluate the 18-month clinical performances of two different one-step dentin adhesives that were applied alone or with an additional hydrophobic adhesive layer to non-carious cervical lesions. The hypotheses are that (1) Additional Hydrophobic Adhesive layer application can provide better clinical performance in class V restorations and, (2) the HEMA content will cause statistically different clinical performances.
