Differential expression of salivary glycoproteins in aggressive and chronic periodontitis.
The aim of this study was to compare the pattern of secretion and the expression of mucin glycoprotein-2 (MG2) and lactoferrin in individuals with or without periodontitis. Five individuals with aggressive periodontitis (APG), 5 with generalized chronic periodontitis...
Effectiveness of different carbamide peroxide concentrations used for tooth bleaching: an in vitro study.
This in vitro study evaluated the effectiveness of three carbamide peroxide concentrations used for tooth bleaching treatments. Sixty bovine dental slabs (6x6x3 mm) were obtained, sequentially polished, submitted to artificial staining (baseline) and randomized into f...
Influence of ferrule preparation with or without glass fiber post on fracture resistance of endodontically treated teeth.
Apoptosis of human tongue squamous cell carcinoma cell (CAL-27) induced by Lactobacillus sp. A-2 metabolites.
To study the effect of Lactobacillus sp. A-2 metabolites on viability of CAL-27 cells and apoptosis in CAL-27 cells. Lactobacillus sp. A-2 metabolites 1 and 2 (LM1 and LM2) were obtained by culturing Lactobacillus sp. A-2 in reconstituted whey medium and whey-inulin medium; the cultured CAL-27 cells...
Frictional resistance of self-ligating versus conventional brackets in different bracket-archwire-angle combinations.
To compare the influence of archwire material (NiTi, beta-Ti and stainless steel) and brackets design (self-ligating and conventional) on the frictional force resistance. Two types of brackets (self-ligating brackets - Smartclip, 3M/Unitek - and conventional brackets - Gemini, 3M/Unitek) with three...
Antimicrobial and fluoride release capacity of orthodontic bonding materials.
The aim of this study was to evaluate the antimicrobial and fluoride releasing capacity of 3 bonding materials. Thirty nine specimens with standardized surface smoothness and dimensions were prepared. The antimicrobial capacity of the materials against S. mutans, L. casei and C. albicans was evaluat...
Rehabilitative treatment of cleft lip and palate: experience of the Hospital for Rehabilitation of Craniofacial Anomalies/USP (HRAC/USP) - P...
The Laboratory of Physiology provides support for the diagnosis of functional disorders associated with cleft lip and palate and also conducts studies to assess, objectively, the institutional outcomes, as recommended by the World Health Organization. The Laboratory is conceptually divided into thre...
Effect of low-level laser therapy on pain levels in patients with temporomandibular disorders: a systematic review.
Temporomandibular disorders (TMD) are characterized by the presence of temporomandibular joint (TMJ) and/or masticatory muscle pain and dysfunction. Low-level laser is presented as an adjuvant therapeutic modality for the treatment of TMD, especially when the presence of inflammatory pain is suspect...
The influence of "C-factor" and light activation technique on polymerization contraction forces of resin composite.
This study evaluated the influence of the cavity configuration factor ("C-Factor") and light activation technique on polymerization contraction forces of a Bis-GMA-based composite resin (Charisma, Heraeus Kulzer). Three different pairs of steel moving bases were connected to a universal testing mach...
Mechanisms of action of systemic antibiotics used in periodontal treatment and mechanisms of bacterial resistance to these drugs.
Antibiotics are important adjuncts in the treatment of infectious diseases, including periodontitis. The most severe criticisms to the indiscriminate use of these drugs are their side effects and, especially, the development of bacterial resistance. The knowledge of the biological mechanisms involve...
