BACKGROUND Conventional non-steroidal anti-inflammatory drugs have been widely used in the control of postoperative pain, but sparse information is available on the efficacy of celecoxib, a selective cyclooxygenase-2 inhibitor, or dexamethasone, a steroidal anti-inflammatory drug, after periodontal surgeries. The purpose of the present study was to compare(More)
Considering the current high consumption of energy drinks, the aim of the present study is to evaluate the influence of energy drinks in removing the smear layer and exposing dentinal tubules on root surface. Dentine root surfaces were exposed using a diamond bur. Forty movements of scaling were performed in the area prepared in order to create a smear(More)
OBJECTIVE The aim of this study was to investigate the relationship between quality of root canal obturations and the presence/absence of periapical lesion in elderly patients. METHODOLOGY This was a systematic conducted by means analysing studies on the quality of root canal obturations and their relationship with periapical health in elderly patients.(More)
AIM The aim of the present study was to compare the removal of the smear layer and exposure of collagen fibers of the root surface following the application of five citric acid solution concentrations. METHODS AND MATERIALS Two hundred seventy (270) samples were equally divided into six groups (n=45) for treatment with saline solution (control) and five(More)
Although in vitro studies have shown encouraging results for root surface conditioning with demineralizing agents, in vivo studies have failed to show its benefits in periodontal healing. This can be attributed to several factors, among which, the hypermineralization of dental surface. Therefore, this in vitro study compared, using scanning electron(More)
OBJECTIVES The aim of this study was to establish the parameters of concentration, time and mode of application of citric acid and sodium citrate in relation to root conditioning. MATERIAL AND METHODS A total of 495 samples were obtained and equally distributed among 11 groups (5 for testing different concentrations of citric acid, 5 for testing different(More)
Considering the current high use of high fluoride toothpastes, the aim of the study was to quantify alterations in the root dentine permeability submitted to treatment with a high fluoride toothpaste and 8% arginine, calcium carbonate, sodium monofluorophosphate toothpaste as a preventive treatment for dentinal tubules exposure followed by acid challenge.(More)
This study analyzes the clot stabilization on root surfaces of teeth impregnated with cotinine and nicotine and the influence of the scaling in the adhesion of blood components, observing the influence of new exposition to nicotine and/or cotinine after scaling. Fifteen human teeth extracted due to periodontal disease of non-smokers patients were selected(More)
