Our study evaluated and compared the postoperative sensitivity of the placement technique (incremental and bulk fill) in class II posterior composite resin restorations bonded with two different adhesive strategies (self-etch and etch-and-rinse).Sixty patients were randomly selected, their age range from 25 to 40 years old. They were divided into 2 main groups according to the packing technique of composite material; incremental Tetric Evoceram and Tetric Evoceram bulk fill composite.30 patients (n=30) were selected for incremental Tetric Evoceram composite restorations and they were equally divided according to the adhesive systems used (etch and rinse or self-etch adhesive strategy) (n=15 teeth).30 patients (n=30) were selected for Tetric Evoceram bulk fill composite restorations and they were equally divided according to the adhesive systems used (etch and rinse or self-etch adhesive strategy) (n=15 teeth).Post-operative pain assessed at 24 hours, 1 week and 1 month using the visual Analog Scale Score (VAS).Each patient was instructed to place a vertical mark on the VAS line at home to indicate the intensity of pain at each assessment period.
This study aims to compare the sensitivity of detecting Chlamydia trachomatis, Neisseria gonorrhoeae and Mycoplasma genitalium by real-time multiplex PCR in a pooled analysis (i.e. gathering pharyngeal, anorectal and urinary samples) versus the standard of care (where a real-time multiplex PCR is made in each of the three samples).
Response Evaluation Criteria in Solid Tumors (RECIST) are insensitive in evaluating primary sarcoma originated from bone treated with chemotherapy or targeted therapy, which did not have the definition of measurement methods either. This study evaluates whether clinical imaging findings of sarcoma after preoperative chemotherapy correlate with tumor responses by pathological evaluation by Huvos classifications and develops reliable, quantitative, clinical response criteria.
Exposure to acute intermittent hypoxia (AIH) can facilitate of motor output but no studies of sensory effects has been reported.
Bleeding on probing demonstrated to have high specificity with certain level of sensitivity to detect periodontal disease. Again, understanding the weak hemidesmosome attachment to the implant surface is imperative to discern on the probe penetration extent and subsequent bleeding. In the presence of inflammation, bleeding should be present indicating high sensitivity when probing deeper sites; nevertheless the lack thereof in healthy condition does not seem to translate high specificity. In this sense, it is noteworthy to mention that the mucogingival shift after implant placement often decreases the presence of keratinized mucosa, triggering a greater inflammatory condition on the peri-implant tissues. Thereupon, bleeding on probing, although might reliably indicate presence of disease, it does not seem to be a suitable diagnostic parameter. On the other side, suppuration characterizes the necrosis of peri-implant tissues, being rich in polymorphonuclear cells and as such, a sensitive indicator of bone turnover. In this sense, it must be noted that, if detected in early stages where bone resorption has not occurred yet, it might be a consequence of a foreign body reaction (i.e., residual cement or floss). Therefore, in the diagnosis of peri-implantitis, radiographic examination must be always incorporated to the clinical assessment as the 'gold standard'. Hence, the aim of this case-control study was to assess the diagnostic accuracy of peri-implantitis-related clinical parameters compared to otherwise healthy dental implants.
Introduction: The pain sensitivity associated with whitening is the main problem reported by patients during dental whitening, and the use of desensitizing dentifrices is an alternative for the treatment of sensitivity. Objective: To evaluate clinically the influence of desensitizing dentifrices applied through a plastic tray, reducing the pain sensitivity and color variation caused by the technique of in-office dental whitening, through a controlled double-blind clinical study. Methods: A longitudinal prospective study was conducted with 48 individuals, 18 years and 30 years of age, without gender distinction, who underwent in-office dental whitening using 35% hydrogen peroxide (Whiteness HP, FGM, Joinville , SC, Brazil) in three clinical sessions with a one-week interval between them. The volunteers used in the night for each bleaching session a plastic tray for 4 hours containing one of the dentifrices related to the experimental groups: Group 1 (Control) - Sucralose (S) (Biotype - Manipulation pharmacy); Group 2 (Active control) - Sodium fluoride (FS) with 1450ppm of fluorine (Close up triple, Unilever); Group 3 - Arginine, calcium carbonate (ACC) and sodium monofluorophosphate with 1450 ppm fluorine (Colgate sensitive pro-relief, Colgate-Palmolive); Group 4 - 5% potassium nitrate (NP) and sodium fluoride with 1450 ppm fluorine (Sensodyne pro-enamel, GlaxoSmithKline). The evaluation of the sensitivity associated with the times of use of the plastic tray in the first session (S1: sensitivity before the tray, S2: sensitivity after the tray), in the second session (S3: sensitivity before the tray, S4: in the third session (S5: sensitivity before the tray, S6: sensitivity after the tray) used the analog numerical scale with scores from 0 to 10 and for the color evaluation the spectrophotometer (Easyshade, Vident, Brea, CA, Obtaining the data that were used in the CIELab system. The data were submitted to the multivariate analysis of variance (MANOVA) with repeated measurements and Lambda Wilks test with a 5% probability level to differentiate the groups. In addition, the factorial variance analysis (ANOVA) in one criterion was applied. Values of p <0.05 were considered statistically significant.
Adult soft tissue sarcomas (STS) are rare tumours with an estimated incidence averaging 5/100 000/year in Europe. The prognosis of soft tissue sarcomas is dominated by local recurrence and distant metastasis. A link seems to exist between local recurrence and overall survival. Local recurrence occurs in approximately 16-29% of STS of the limbs. A combination of resection and radiotherapy is the optimal treatment of primary tumours according to histological grade and surgical result. Modern imaging techniques such as ultrasound (US), magnetic resonance (MR) and computed tomography (CT) are normally used to rule-out a recurrence in patients operated on for STS. However, none of this technique is perfect and different advantages and drawbacks have to be considered in choosing one or another technique. In the past, US was used in tumour follow-up to detect tumour recurrences, however these studies didn't use high-resolution transducers and the timing of imaging respect to surgery was not defined. The recent advances in transducer technology improved the diagnostic capabilities of US. For the evaluation of limbs soft-tissue masses, US is widely used as a first level modality. The reasons are that US is widely available, fast, easily repeatable and often more accessible than CT and MR Imaging. In addition, US equipped with high-frequency transducers have a spatial resolution that may be comparable or higher than that of MR Imaging and CT in the evaluation of superficial soft-tissues. US and MR Imaging are often not able to differentiate benign from malignant tumours, therefore several lesions detected with US or MR Imaging warrant biopsy. The clinical practice guidelines of the ESMO (European Society of Medical Oncology) published in 2010 found that there are no published data to indicate the optimal routine follow-up policy of surgically treated patients with localized disease. Moreover, it has not been demonstrated that, for limb sarcomas recurrences, MR Imaging is superior and cost-effective compared to US for the assessment of the primary site. Considering that surgically treated intermediate-/high-grade patient may be followed frequently, even every 3-4 months in the first 2-3 years and considering that performing US is easier than having MR Imaging, the purpose of this study is to evaluate the diagnostic performance of US in the detection of local recurrences of adults patients with soft tissue sarcomas of the limb.
There are few data on elderly people concerning mechanisms involved in the in vivo release and perception of aromatic compounds. Any knowledge on this point would be of great interest to the scientific community. Concerning the dimensions of sensory perception and in-mouth comfort, there is, to our knowledge, no methodology to describe them. These dimensions are truly original and innovative, and investigating them will lead to the development of foods adapted to elderly populations with chewing and salivation disorders. The expected results are: - to obtain two groups of subjects with differences in chewing abilities and saliva production - the characterization of flavour release profiles in elderly subjects with regard to oral physiology (mastication and salivation) and saliva composition - a sensory profile describing in-mouth comfort when food is eaten
