OBJECTIVES To evaluate the efficacy of locally delivered doxycycline as an adjunct to non-surgical treatment with the use of an ultrasonic device compared to scaling and root planing using hand instruments, by means of clinical and microbiological criteria. MATERIAL AND METHODS Thirty three patients with chronic periodontitis participated in this cohort study and were divided into two groups....

The purpose of the present study was to investigate the appearance of periodontally involved root surfaces after hand scaling and after using two different piezoelectric ultrasonic scalers. Further, the root surfaces were examined by a scanning electron microscope after they have been treated with saline, saturated citric acid, saturated tetracycline hydrochloride or 8% EDTA for 3 minutes. Thir...

Abstract The efficiency and longevity of components in geothermal plants are significantly reduced by mineral deposition pipes, also known as scaling [1]. A number methods used to monitor fouling (a broader term for all types organic inorganic deposition) other industries, such the oil, gas food industries. These include direct indirect, offline, in-situ online, well inline methods, each which ...

The aim of this study was the morphological evaluation root surfaces subjected to manual (curette) and ultrasonic (conventional diamond tips) scaling. surface then polished with a rubber cup three medium-sized pastes. Ninety teeth were randomly divided into groups 30 different instrumentation: (1) instrumentation Gracey® curette; (2) standard steel tip (Universal Perio S-SERIES: USU, Hu-Friedy,...

Black staining of the teeth in children and adolescents does not cause pain or serious illness, but it can be socially debilitating for esthetic reasons. is easily removed through periodic professional mechanical tooth cleaning ultrasonic scaling, recur within few months. Using essential oil-containing mouth rinses diluted at 50% twice per day could prevent black from returning after removed, r...
