https://www.selleckchem.com/products/piperaquine-phosphate.html The aim of the present study was to evaluate the cyclic fatigue, torsional resistance and surface roughness of Reciproc R25 instruments in four different situations, namely as new instruments and as instruments tested after clinical preparation of one, two or three maxillary molars with four root canals. The total time required to perform each root canal preparation was recorded. Cyclic fatigue resistance was determined by the time to fracture using a customized testing device (n = 10 per group). The torsional test evaluated the torque and angle of rotation to failure according to ISO 3630-1 (n = 10 per group). The roughness of the working parts of new and used instruments was evaluated with a profilometer (n = 5 per group). Statistical analysis was performed using one-way ANOVA and Tukey's test. The level of significance was set at 5%. No fractures or deformations were observed after clinical use. Higher preparation time was needed during the third use of the instruments for all root canals (p 0.05). Regarding the roughness measurements, groove depth was higher on new and one- versus two- or three-maxillary-molar-prepared instruments (p less then 0.05). It can be concluded that the clinical use of Reciproc instruments increased preparation time and decreased surface roughness. However, clinical use did not affect the cyclic fatigue or torsional resistance of the Reciproc instruments.[This corrects the article doi 10.1590/1413-812320202512.21292020].The scope of this study was to analyze the relationship between quality of life, fatigue and injuries among professional Brazilian ballroom dancers. A total of 320 professionals from the five regions of Brazil participated, and the data were collected through a self-administered online questionnaire concerning general information, WHOQOL-bref, Yoshitake Fatigue Questionnaire and Injury Identification in Dancers Questionnaire. For data analysis, descriptive s
