In natural ecosystems, micro‐organisms grow preferentially attached to surfaces, forming matrix‐enclosed biofilms. The aim of this study was determine photodestruction levels in biofilms after subjecting them photodynamic therapy. Biofilms Streptococcus mutans , S. sobrinus and sanguinis were grown on enamel slabs for 3, 5 or 7 d. Both the number viable concentration water‐insoluble polysaccharides analysed, mineral loss ( Δ Z) analyses performed slabs. antimicrobial potential toluidine blue...
The aim of this study was to compare different treatments for dentin hypersensitivity in a 6-month follow-up. One hundred and one teeth exhibiting non carious cervical lesions were selected. assessment method used quantify sensitivity the cold air syringe, recorded by visual analogue scale (VAS), prior treatment (baseline), immediately after topical treatment, 1 week, 1, 3 6 months. Teeth randomly assigned five groups (n = 20): G1: Gluma Desensitizer (GD); G2: Seal& (SP); G3: Oxa-gel (OG);...
Studies have shown that bleaching agents interfere with the adhesion of composite resin placed immediately after bleaching.The aim this study was to evaluate shear bond strengths four different durations since time nonvital (1 d and 1, 2, 3 wk).Two hundred seventy bovine teeth were assigned nine groups (n = 30) according bleach used between restoration: group 1--sodium perborate (SP), 1 day (AB); 2--SP, week AB; 3--SP, 2 weeks 4--SP, 5--37% carbamide peroxide (CP), 6--CP, 7--CP, 8--CP,...
ABSTRACT The objective of this in vitro study was to quantitatively assess the effects bleaching with 10 and 15% carbamide peroxide (CP) on restoration materials by performing superficial micro‐hardness analysis. Acrylic cylindrical containers (4 × 2 mm) were filled following products: Charisma (Heraues Kulzer, Vila Santa Catarina, São Paulo, Brazil), Durafill VS (Heraeus Kulzer), Vitremer (3M, Sumaré, Dyract (Dentsply, Petropölis, Rio de Janeiro, Permite C (SDI, Brazil). Sixty samples...
Objectives/Hypothesis Children with cleft lip and palate (CLP) often suffer from nasal obstruction that may be related to effects on volume. The objective of this study was compare side:side volume ratios in patients unilateral (UCLP) bilateral (BCLP) clefts age‐matched controls. Study Design Retrospective case–control using three‐dimensional (3D) airway reconstructions. Methods We analyzed 20 subjects (age range = 7–12 years) UCLP BCLP a regional craniofacial center who underwent cone beam...
summary The preservation and restoration of severely weakened pulpless teeth is a difficult relatively unpredictable procedure. This study evaluated the resistance to fracture experimentally bovine roots internally reconstructed with different filling materials in combination prefabricated post compared restored that were intact. 75 mandibular incisors similar bulks selected. Of these, 60 prepared standardized dimensions, thereby simulating weakness. All filled restorative materials....
ABSTRACT Purpose : The purpose of this investigation was to evaluate the influence phosphoric acid pretreatment on shear bond strength two self‐etching bonding systems enamel and dentin. Materials Methods: Forty‐eight extracted third human molar teeth were mounted, embedded into polystyrene resin, polished with 600‐grit aluminum oxide papers, randomly divided four groups ( n = 12): group 1–Clearfil Liner Bond® 2V (Kuraray Co. Ltd., Osaka, Japan); 2–One Up Bond F® (Tokuyama Corp., Tokyo,...
Clinical Relevance Bond strength is affected by the combination of thermal and mechanical load cycling. However, results vary greatly with number cycles adhesive system type (total or self-etching).
Background: Clefts of the lip and/or palate (CL/P) carry a social stigma that often causes psychosocial stress. The purpose this study was to consider association cleft phenotype and age with self-reported aspects Methods: Children nonsyndromic CL/P unaffected children born between 1997 2003 were identified through North Carolina Birth Defects Monitoring Program birth records, respectively. concerns assessed via 29-question subset larger survey. Responses analyzed according school (cleft...
An early childhood carie (ECC) is an extremely destructive form of tooth decay. The aim this study was to investigate the action ozone (O3), and association sodium fluoride (NaF) with chlorhexidine (CHX) on bacteria related ECC. Overnight culture performed. On exponential phase suspension adjusted (101-108 CFU/mL). A drop (10μL) each concentration applied sheep blood agar plates treated O3 (2, 20, 200, 2,000 ppm); after 18 hours, recovery analysis CFU verified reduction bacterial activity....
ABSTRACT Purpose: The purpose of this study was to investigate the surface roughness (Ra) different esthetic restorative materials following simulated toothbrushing using whitening dentifrices. Materials and Methods: Cylinders Esthet-X (Dentsply Caulk, Milford, DE, USA), Durafil VS (Heraeus Kulzer, Wehrheim, Germany), Vitremer (3M ESPE, St. Paul, MN, USA) were made molds (4 mm in diameter for 2 height). superficial evaluated a profilometer with cutoff length 0.25 speed 0.1 mm/s. specimens (N...
Background: The aesthetic aspects of the cleft lip nasal deformity have been appreciated for over a century, but functional implications remained largely underappreciated or misunderstood. This study describes frequency and severity obstructive symptoms among children with and/or palate, addressing hypotheses that age, type, are associated development symptoms. Methods: Children nonsyndromic palate comparison group unaffected born from 1997 to 2003 were identified through North Carolina...
