Volatile sulphur compounds in people with chronic kidney disease and the impact on quality of life.

The objectives are to identify volatile sulphur compounds (VSCs) in individuals with Chronic Kidney Disease (CKD) and to relate quality of life and oral health. A case-control study with 32 individuals with CKD in haemodialysis in the study group (SG) and 32 healthy individuals in the control group (CG) was performed. The VSCs were identified by gas chromatograph before (BC) and after cysteine (AC) mouthwash and an organoleptic test.

Efficacy of Ketoprofen With or Without Omeprazole for Pain And Inflammation Control After Third Molar Removal.

In view of the gastrointestinal problems generated by the ketoprofen use, the ketoprofen association with omeprazole is available on the market. However, this association efficacy in acute pain control has not been established. Bilateral extraction of lower third molars in similar positions is currently the most used model for the evaluation and investigation of the efficacy and pharmacological effects of new compounds for the treatment of acute postoperative pain.

Mandibular ramus length as an indicator of chronological age and sex.

Age and sex estimation is crucial in forensic investigations, whether in legal situations that involve living people or to identify mortal remains. The aim of this study was to establish reference values in a Brazilian population to estimate age and sex by measuring the length of the mandibular ramus on lateral cephalometric radiographs, and to determine the probability that an individual being is 18 years or older, based on the results that were obtained. Two hundred and eighteen scanned lateral cephalograms of individuals between 6 and 20 years of age (101 males and 117 females) were measured with reference to mandibular ramus length (the distance between Condylion superior (Cs) and Gonion (Go)) using ImageJ 1.
