Local IL-10 level as a predictive factor in generalized aggressive periodontitis treatment response.

Generalized aggressive periodontitis (GAgP) presents a reduced response to non-surgical therapy. However, it is not clear if the initial clinical, microbiological or immunological characteristics are impacting the worse response to treatment. This study aimed to identify the predictive value of clinical, microbiological and immunological patterns on the clinical response to therapy in GAgP patients.

Effect of whitening dentifrices on the surface roughness of a nanohybrid composite resin.

Objectives: The present study verified the influence of whitening dentifrices on the surface roughness of a nanohybrid composite resin.

Materials And Methods: Thirty-two specimens were prepared with Filtek™ Z350 XT (3M/ESPE) and randomly divided into four groups (n = 08) that were subjected to brushing simulation equivalent to the period of 1 month. The groups assessed were a control group with distilled water (G1), Colgate Total 12 Professional Clean (G2), Sensodyne Extra Whitener Extra Fresh (G3), and Colgate Luminous White (G4).

Fluoride stability in dentifrices stored in schools in a town of northern Brazil.

The aim of this study was to analyze fluoride stability in dentifrices stored during nine months in schools from Careiro da Várzea, State of Amazonas, Brazil. Analysis of total fluoride concentration, total soluble fluoride, and ionic fluoride in the dentifrice samples was performed in four different time periods: at the time of purchase (baseline); after three months, after six months, and after nine months of storage. Fluoride concentration was determined using a specific electrode (Orion 96-09) connected to an ion analyzer (Orion A-720) and calibrated with fluoride standard solutions containing 2.

Periodontal clinical and microbiological characteristics in healthy versus generalized aggressive periodontitis families.

Aim: Generalized aggressive periodontitis (GAP) is a severe and multifactorial disease in which a familial aggregation and a specific microbiological profile have been suggested. Thus, this case-control study evaluated the clinical and subgingival microbial profile of GAP subjects and their families compared to healthy families.

Methods: Fifteen families with parents presenting periodontal health and 15 with parents with a history of GAP were selected.

Full-mouth ultrasonic debridement associated with povidone iodine rinsing in GAgP treatment: a randomised clinical trial.

Objective: This study evaluated the clinical, immunological and microbiological results of full-mouth ultrasonic debridement (FMUD) with 10 % povidone iodine (PVPI) as the cooling liquid in the treatment of generalised aggressive periodontitis (GAgP).

Material And Methods: Twenty-eight patients presenting GAgP were randomly assigned to one of the following groups for evaluation: FMUD + SS (n = 14)--single session of FMUD with 0.9 % saline solution as cooling agent and FMUD + PVPI (n = 14)--single session of FMUD with PVPI solution as cooling agent.

Efficacy of a combined in-office/home-use desensitizing system containing 8% arginine and calcium carbonate in reducing dentin hypersensitivity: an 8-week randomized clinical study.

Purpose: To determine the efficacy in reducing dentin hypersensitivity (DHS) of a combined in-office and home-use desensitizing system, each product containing 8% arginine and calcium carbonate (Test), following a dental scaling procedure, compared to the combination of a conventional prophylactic paste and a potassium nitrate dentifrice (Control), in a group of patients with known dentin hypersensitivity.

Methods: An 8-week clinical study, with 50 subjects, was conducted in Piracicaba, São Paulo, Brazil, using a double-blind/two treatment design. Air blast sensitivity assessments were used to compare the efficacy of the two approaches using both the Schiff scale as well as a Visual Analogue Scale (VAS).

Esthetic and functional rehabilitation via reattachment of dental fragments.

Anterior teeth fractures are frequently encountered in clinical practice. The reattachment of dental fragments, if possible, is a conservative and effective technique, which is utilized in this case. This case presentation concerns an 18-year-old male patient with a root-crown fracture of the left maxillary central incisor, which involves the periodontal biologic space.

Radiographic characteristics of furcation involvements in mandibular molars as prognostic indicators of healing after nonsurgical periodontal therapy.

Background: The authors conducted a study to evaluate the radiographic characteristics of Class II mandibular furcation involvements as prognostic indicators of healing after nonsurgical periodontal therapy.

Methods: Twenty-three patients with chronic periodontitis (Class II furcation involvements in mandibular molars, probing pocket depth [PPD] of 5 millimeters or greater and bleeding on probing [BOP]) were selected to receive nonsurgical periodontal treatment. The authors evaluated visible plaque index, BOP, position of the gingival margin, PPD, relative attachment level (RAL) and relative horizontal attachment level.
