SUMMARY Objectives: The objective of the present study was to compare bleaching efficacy (BE) and tooth sensitivity (TS) in-office applied under different time protocols. Methods Materials: Fifty-three patients were randomly distributed into three groups: agent in one (1×15), two (2×15), or (3×15) 15-minute applications. labial surfaces anterior teeth bleached using a 35% hydrogen peroxide gel. Two sessions with one-week interval between performed. shade evaluation performed visual guide...
Bioactive endodontic sealers have been developed to improve the quality of root canal obturation. EndoSequence Bioceramic (BC) Sealer is amongst calcium silicate-based materials recently for permanent filling. The objective this study was evaluate bioactivity BC and its micro push-out bond strength dentin compared AH-Plus (AH) sealer.To perform test, 24 canals mandibular premolars were instrumented divided into two groups (n=12). Each cut 4 slices lumens filled with submitted test. Failure...
ABSTRACT Statement of the Problem: Eugenol is a radical scavenger that inhibits polymerization resin materials. Little known about effect eugenol‐containing temporary restorative material on resin‐dentin bond strength adhesive systems partially dissolves and modifies smear layer. Purpose Study: The aim this study was to evaluate restoration (zinc oxide eugenol [ZOE]) microshear etch‐and‐rinse self‐etch adhesives. Material Methods: roots 18 human molars were removed crowns teeth transversally...
Abstract Aim The present randomized, controlled prospective study evaluated the histomorphological response of human dental pulps capped with two grey mineral trioxide aggregate (MTA) compounds. Methodology Pulp exposures were performed on occlusal floor 40 permanent pre‐molars. pulp was either ProRoot (Dentsply) or MTA‐Angelus (Angelus) and restored zinc oxide eugenol cement. After 30 60 days, teeth extracted processed for histological examination effects scored. data subjected to...
The aim of this study was to evaluate, over an 18-month period, the clinical performance a self-etch adhesive [Transbond Plus Self Etching Primer (SEP), 3M Unitek] compared with conventional that employs etch-and-rinse approach (Transbond XT, Unitek). One operator, using straight-wire technique, bonded 567 metallic brackets teeth 30 patients (age range 12–18 years) in way acted as self-control. were following manufacturers' instructions except for fact system brushed longer time than...
Abstract Aim To characterize an experimental gutta‐percha and niobium phosphate glass composite ( GNB ) applied with a thermoplastic technique to the root canals without sealer in moist environment evaluate its micropush‐out bond strength canal wall dentine. Methodology The of sixty human mandibular pre‐molars were prepared using rotary NiTi instruments irrigation sodium hypochlorite EDTA . teeth then randomly divided into three groups according filling material used: AH plus ), EndoSequence...
The study aimed to evaluate the effectiveness of in-office bleaching and associated tooth sensitivity on application nano-calcium phosphate paste as desensitizing agent. Bleaching was performed with 35% hydrogen peroxide gel in 40 patients who were randomly divided into placebo groups. efficacy (BE) evaluated using a value-oriented Vita shade guide. Tooth recorded numeric rating scale (0–4) during up 48 h after each session. primary outcome absolute risk compared Fisher’s exact test (α =...
This study evaluated pH and release of calcium, sodium phosphate ions from different medications in human dentin. Fifty premolars were prepared randomly divided into groups: (CHX) - 2% chlorhexidine gel; (CHX + CH) CHX calcium hydroxide PA; (CH) CH propylene glycol 600; (NPBG) experimental niobium bioactive glass distilled water; (BG) (Bio-Gran) water. The specimens immersed deionized water the variations measured. quantification solutions was made by inductively coupled plasma atomic...
This study evaluated the effect of air-drying time and light-curing on degree conversion (DC) three etch-and-rinse adhesive systems: ONE-STEP (OS) plus (OSP), Ambar (AMB), two multimode All-Bond Universal (ABU) ScotchBond (SBU) by Fourier transform infrared (FTIR) analysis. The DC each system was analyzed with six experimental different protocols: (1) immediate light curing for 10 s without solvent volatilization; (2) volatilization air stream curing; (3) 60 (4) 20 (5) (6) curing. FTIR...
To evaluate the compressive strength and fluoride ion release of conventional resin-modified glass ionomer cement mixing methods (hand mix mechanical mix) compared to ready-to-use ones. Two cements (GICs) (Fuji II Fuji Caps), two GICs LC L one GIC (Ionoseal, Voco) were used. For test, cylindrical specimens (6 mm × 4 mm) each group prepared. The test was performed in a universal testing machine (EMIC DL2000). prepared form discs placed deionized/distilled water, which replaced daily for 15...
ABSTRACT Objective: To evaluate the influence of photoinitiators on physicochemical properties simplified conventional adhesive systems. Material and Methods: Three systems were tested: Adper Single Bond 2 (3M), Ambar (FGM), APS (FGM). For cohesive strength (CS) test, specimens (n =10) prepared subjected to mechanical testing in a universal machine (Instron 3342). cross-link density (CLD) eight each material Knoop microhardness measurements before after immersion ethanol for 24 hours....
Abstract – Aim: To evaluate the influence of calcium hydroxide (CH) paste used as intracanal medication on bond strength AH Plus (AH) and Epiphany (EP) sealers to root dentin. Methodology: Sixty palatal canals were prepared in human maxillary first molars, using a rotary system. Half specimens received distilled water, other ones with CH for 14 days. Thereafter, was removed both groups further divided into two subgroups, filled either or EP. The test submitted micropush‐out at speed 0.5 mm...
