The objective of this study was to evaluate the discolouration effects artificial saliva, granule lemon juice, coffee (without sugar), coca cola, sour cherry fresh carrot juice and red wine on resin-based composite materials that are commonly used in restorative dentistry.Colour four brands resin composites (Filtek Z 250 (3M Espe), Filtek Supreme Quadrant (Cavex), Charisma (Heraeus-Kulzer)) A2 shade measured after one day immersion eight different solutions. Colour measurements were obtained...
Background: This study is to examine the surface roughness and color changes occurring on composite resins following application of different finishing polishing systems.Material Methods: In our study, a total 200 samples were prepared from composites resin (6×2 mm) containing supra-nano, submicron hybrid, nanohybrid, nano-ceramic microhybrid filler.They polished with diamond, aluminum oxide, silicon carbide systems.The initial values measured spectrophotometer profilometer.After that,...
The purpose of the present study was to compare effects three methods removing adhesive on enamel surface roughness and dental pulp temperature.Ninety human maxillary premolars were randomly divided into groups (n=30) according type clean-up procedure: aluminum oxide-based burs, erbium-doped yttrium garnet (Er:YAG) laser, tungsten carbide bur. measured using a non-contact optical profilometer. After first readings (T1), orthodontic brackets attached with composite. teeth debonded bracket...
Objective: To evaluate the effect of extrusion on immature permanent tooth PBF values during a 6-month post-trauma period and to compare accuracy cold tests pulp sensibility traumatized teeth with that electric (EPT).Methods: The study group comprised 26 extruded maxillary incisors in 25 trauma patients. respective contralateral homologous (n=25) were included as positive control group. Teeth treated by repositioning splinting. Pulp vitality readings for taken LDF, EPT test day...
Purpose: This study investigated discoloration and surface roughness (Ra) of resin-based computer aided design (CAD)/computer manufacturing (CAM) blocks direct indirect resin composites after staining with coffee. Materials & Methods: Using a Teflon mold, 60 disc shaped specimens (8×2 mm2) were fabricated from (Estelite Asteria GrandioSO) (Gradia Plus) composites, 30 CAD/CAM (12×14×2 mm3) prepared composite (Vita Enamic, Brilliant Crios, Cerasmart) (n=10). A contact type profilometer was...
Aim: Resin-containing restorative materials are widely used in the restoration of teeth. Our aim this study is to examine color change beverages consumed cold on resin-containing materials. Methodology: Samples were prepared using composite resins and resin-based CAD/CAM blocks. All samples kept tea, coffee, coke, energy drink, distilled water after polishing. The values measured with a spectrophotometer at beginning, 1st, 7th 30th days, calculated CIEDE2000 formula. Statistical analysis was...
Purpose:Since conventional composite resins have some disadvantages such as polymerization shrinkage and secondarycaries formation, indirect restorations are preferred in cases where tooth tissue loss is high. The aim of this study toexamine the water absorption color change different beverages.Materials & Methods:In study, 40 specimens (10×2 mm) were arranged from each using three indirect(Signum Composite, Signum Ceramis Gradia Plus) one (GrandioSO) resin. After thespecimens polished,...
ABSTRACT Aim The aim of this study was to evaluate the minimum bactericidal concentrations (MBC) root-end filling materials ProRoot MTA, MTA Angelus and IRM. Materials methods Macrodilution broth method used. Microorganisms used were: Staphylococcus aureus (ATCC 29213), Enterococcus faecalis 29212) Streptococcus mutans . Serial two-fold dilutions samples were prepared in macrodilution tubes with ranging from 1/2 1/512. incubated for 24 hours. After incubation, 0.1 ml diluted culture...
Amaç: Son yıllarda 3D yazıcı kullanılarak geçici ve daimi dental restorasyonlar üretilmektedir. Bu çalışmadaki amacımız; yazıcıda rezinlerinden üretilen örneklere farklı yüzey temizliği uygulamasının mikrosertlik adeziv siman ile makaslama bağ dayanımı etkisini incelemektir. Gereç Yöntemler: Çalışmada SLA DLP baskı özelliklerine sahip yazıcılar kullanıldı. restorasyon (Crowntec, Saremco Permanent Crown, Formlabs) 44 adet örnek üretildi. Üretimden sonra örneklerin yarısı 3 dk izopropil alkole...
Amaç: Bu çalışmada, 2 farklı şekilde polimerize olabilen bir alkasit materyalin kendiliğinden veya çift fazlı sertleştirildiğinde mikrosızıntı açısından değerlendirilmesi ve diş rengindeki restoratif materyaller ile karşılaştırılması amaçlanmıştır.
