background and aims. the aim of this clinical investigation was to compare clinical and microbiological effectiveness of adjunctive chx gel in the treatment of periodontitis. materials and methods. twenty-four subjects with localized or generalized moderate-to-severe chronic periodontitis underwent scaling and root planing. one tooth in each quadrant with a probing depth of >4 mm was chosen for...

OBJECTIVE To compare photodynamic therapy (PDT) as an adjunctive treatment of chronic periodontitis with scaling and root planing (Sc/Rp) in smokers. METHODS This is a split-mouth, single-masked randomized controlled clinical trial conducted at the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia between May 2010 and March 2011. Fifty-four teeth with probing depth of ≥5mm...

BACKGROUND AND OBJECTIVES Scaling and root planing is one of the most commonly used procedures for the treatment of periodontal diseases. Removal of calculus using conventional hand instruments is incomplete and rather time consuming. In search of more efficient and less difficult instrumentation, investigators have proposed lasers as an alternative or as adjuncts to scaling and root planing. H...

In the present paper, a mathematical model is used in order to predict the longitudinal distribution of dynamic pressure on planing hulls. The present model is based on the empirical equations resulted from multitude of experiments that have been carried out over the years on planing boats. These empirical equations are able to predict a longitudinal section of the pressure distribution. The ob...

The lumber of Eucalyptus urophylla×E. camaldulensis was heat-treated at either 180, 190, 200, or 210 oC for 3 h. According to the national forestry standard methods for evaluating the machining properties of lumber, the machining properties (including planing, sanding, boring, mortising, shaping, and turning) of heat-treated and untreated control samples were investigated. The results indicated...

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....

Biofilms are a complex community of microorganisms characterized by the excretion of an adhesive and protective extracellular matrix, microbeto-microbe attachment, structural heterogeneity, genetic diversity, and complex community interactions. Bacteria growing in dental biofilms display an increased tolerance to antibiotics and antimicrobial agents, including those used in dentifrices and mout...

ae is a serious medical condition in which the immune system attacks the brain, impairing function. with rapid diagnosis and appropriate treatment, many patients recover most or all functions. however, not all patients experience full recovery; with approximately 6% mortality and other patients who never regain significant brain and/or bodily functions. autoimmune encephalitis can produce a wid...
