Background The aim of this study was to compare the anti-inflammatory effects of dexamethasone and etoricoxib after third molar extraction.
Material and Methods A prospective, randomized, controlled, split-mouth study was conducted. 19 volunteers were allocated randomly to receive 90mg etoricoxib 1 hour prior to the procedure or 4mg intramuscular dexamethasone immediately after anesthesia. Baseline measurements were obtained preoperatively, and subsequent assessments were made on immediate postoperative, at 72 hours and 7 days after surgery to measure postoperative facial swelling by use of linear measurements, interincisal mouth opening width and visual analog scale score for pain. The amount of analgesics consumed was recorded. Descriptive statistics and the independent-samples t-test were used to compare the two groups at P < 0.05.
Results Dexamethasone was effective in the control roasted edema for measurements of the mandibular angle - wing of the nose and mandibular angle - labial commissure 72 hours after surgery. And for the measurement mandibular angle - mentum, in the time of 72 hours and 7 days. There was no statistically significant difference in relation to pain and trismus.
Conclusions Considering significant results for some measures of the variable edema for the group that used intramuscular dexamethasone and the difference without statistical significance between groups for the other variables studied, we seem to reflect the intramuscular indication of the corticosteroid in a single dosage in relation to the use of etoricoxib as pre-emptive medication. Key words:Corticosteroids, COX-2 selective, third-molar surgery.
Water is the natural resource most likely to impose limits on development in many parts of the world. The deterioration of its quality, caused by untreated effluent discharges, tends to be a threat to public health. In this sense, this work aims to evaluate the performance of the Sewage Treatment Station of Clube Náutico Alvorada, Caratinga / MG, in its start-up process. Laboratory analyzes were performed to determine the efficiency of the anaerobic treatment system in its start-up process in the treatment of tourist wastewater. The parameters analyzed were pH, Temperature, Conductivity, COD, BOD, Dissolved Solids, Suspended Solids and Sedimentable Solids. The average overall efficiencies for BOD and COD were, respectively, 49.50 and 59.96%. The performance of the WWTP can be explained by the variation of the effluent flow and organic load. The stability of the system has not yet been fully achieved, but its treatment has shown good results.
The climate change associated impacts will be sensed worldwide with profound implications for the human population. The sustainability of civilization have been impacted due to anomalous periods of climate and changes in land use. Nowadays, weather forecasts and seasonal weather forecasts are becoming increasingly accurate, as a result of advances in remote sensing, including satellites, science improvements, and increases in computing power. This manuscript aimed to perform spatio-temporal analysis of the surface area of Dom Helvécio Lake, by using data from satellite images associated with geoprocessing techniques. In order to allow inferences about the influence of rainfall regimes, the Mann-Kendall test was also used to evaluate precipitation trends in the region. As an GIS analysis result, a reduction of about 38 ha area over these 14 years has been identified. The Mann-Kendall test result indicated a tendency for significant precipitation to decrease by 87%, since the p-value is less than 0.1282. Given the importance of the theme, the study demonstrated that climate change can be considered in watershed management and public policy making, as the population must adapt to its effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
