Detection of periodontal bacteria in atheromatous plaque by nested polymerase chain reaction.

Background: In recent years, increasing evidence regarding the potential association between periodontal diseases and cardiovascular diseases has been identified. The available evidence underlines the importance of detecting periodontal pathogens on atheromatous plaque as the first step in demonstrating the causal relationship between the two conditions. The main aim of this investigation is to detect periodontitis-associated bacteria from carotid artery atheromatous plaque from patients who received an endarterectomy using strict sample procurement and laboratory procedures.

Immediate efficacy of diode laser application in the treatment of dentine hypersensitivity in periodontal maintenance patients: a randomized clinical trial.

Background: To evaluate the immediate efficacy in the reduction of dentine hypersensitivity (DH) when applying an 810 nm diode laser (DL), and a 10% potassium nitrate bioadhesive gel (NK10%).

Material And Methods: Forty-five consecutive periodontal maintenance patients of both sexes, with a DH >or= 2 on the verbal rating scale (VRS) in one or more teeth, were randomly allocated into three equal groups: 15 patients received DL and placebo gel; 15 patients were tested with a placebo laser and NK10%; and the remaining 15 received a placebo laser and placebo gel. The DH was evaluated at the start of the study, 15 and 30 min.

Evaluation of the efficacy of two potassium nitrate bioadhesive gels (5% and 10%) in the treatment of dentine hypersensitivity. A randomised clinical trial.

Aim: A randomised clinical trial was designed to compare the immediate efficacy (48-96 h) of two treatments with bioadhesive gels with different concentrations of potassium nitrate (NK 5% versus NK 10%) on dentine hypersensitivity (DH). We evaluated DH by means of the use of the evaporative stimulus (ES), as the main outcome, using a placebo control group as reference.

Patients And Methods: Forty-five consecutive patients who, after stimulation with a blast of air, had at least one tooth with DH > or = 2 according to the verbal ratings scale (VRS) scale were selected.
