The purpose of this study was to assess the ability two new calcium silicate-based pulp-capping materials (Biodentine and BioAggregate) induce healing in a rat pulp injury model compare them with mineral trioxide aggregate (MTA).Eighteen rats were anesthetized, cavities prepared capped either ProRoot MTA, Biodentine, or BioAggregate. specimens scanned using high-resolution micro-computed tomography (micro-CT) system evaluated histologically immunohistochemically dentin sialoprotein (DSP).On...
The aim of this study was to evaluate the cytotoxicity, setting time and compressive strength MTA two novel tricalcium silicate-based endodontic materials, Bioaggregate (BA) Biodentine (BD).Cytotoxicity evaluated by using a 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-((phenylamino)carbonyl)-2H-tetrazolium hydroxide (XTT) assay. Measurements 9 heavy metals (arsenic, cadmium, chromium, copper, iron, lead, manganese, nickel, zinc) were performed inductively coupled plasma-mass spectrometry...
The purpose of this study was to investigate the polymerization temperature a bulk filled composite resin light-activated with various light curing modes using infrared thermography according depth and approximation cavity wall.Composite (AeliteFlo, Bisco, Schaumburg, IL, USA) inserted into Class II prepared in Teflon blocks cured LED unit (Dr's Light, GoodDoctors Co., Seoul, Korea) for 20 s. Polymerization measured an thermographic camera (Thermovision 900 SW/TE, Agema Infra-red Systems AB,...
Treatment of non-vital immature teeth with amoxicillin-containing triple antibiotic paste resulting in apexificationA recent treatment option for young patients is revascularization (TAP).However, tooth discoloration was reported the use conventional minocycline-containing TAP.In this case report, TAP used to prevent discoloration.At 1 yr follow up, were asymptomatic on clinical examination and showed slight crown due mineral trioxide aggregate (MTA) filling rather than TAP.Radiographic...
To assess the biological effects, including odontoblastic differentiation of a novel light-curable material (TheraCal), on human dental pulp cells (hDPCs).The hDPCs were isolated from freshly extracted, caries-free third molars. Ten discs TheraCal and MTA (8 mm in diameter 3 height) incubated α-minimum essential medium (α-MEM) supernatant collected. Viability response to was measured using WST-1 assay. RT-PCR real-time PCR used detect gene expression dentine sialophosphoprotein (DSPP) matrix...
In recent in vitro study, it was reported that osteostatin (OST) has an odontogenic effect and synergistic with mineral trioxide aggregate (MTA) human dental pulp cells. Therefore, the aim of this study to evaluate whether OST a MTA on hard tissue formation vivo.Thirty-two maxillary molars Spraque-Dawley rats were used study. An occlusal cavity prepared exposed pulps randomly divided into 3 groups: group 1 (control; ProRoot MTA), 2 (OST 100 μM + 10 mM MTA). Exposed capped each material...
Mucopolysaccharidosis (MPS) is an inherited metabolic disorder caused by a deficiency in enzymes that participate the degradation of glycosaminoglycans (GAGs) such as heparin sulfate and dermatan sulfate.Left untreated, patients show progressive mental physical deterioration due to deposition GAGs organs.Death often occurs cardiac or respiratory failure before reach their early twenties.MPS has several oral dental manifestations.An enlarged head, short neck, open mouth associated with large...
Changes in SIRT gene expression during odontoblastic differentiation of human dental pulp cellsObjectives: The aim this study was to investigate the 7 different sirtuin genes (SIRT1-SIRT7) cells (HDPCs), and determine role SIRTs potential HDPCs.Materials Methods: HDPCs were isolated from freshly extracted third molar teeth healthy patients cultulred inducing media.Osteocalcin (OCN) dentin sialophosphoprotein (DSPP) analyzed evaluate by reverse transcription-polymerase chain reaction...
OBJECTIVE: The aim of this study was to evaluate the effect multiple layers an infection control barrier on micro-hardness a composite resin. MATERIAL AND METHODS: One, two, four, and eight were used cover light guides high-power emitting diode (LeD) curing unit (LCU) low-power halogen LCU. specimens photopolymerized with LCUs barriers, upper lower surfaces measured (n=10). hardness ratio calculated by dividing bottom surface experimental groups irradiated groups. data analyzed two-way ANOVA...
This study was performed to verify the possibility of MTA and calcium sulfate as a pulp capping agent through comparing dental response in dogs after with MTA, sulfate, hydroxide. 24 teeth 2 dogs, 8 month old, were used this study. Under general anesthesia, cervical cavities prepared exposed sterilized #2 round bur high speed handpiece. hydroxide, applied on pulp. Then coronal openin,fs sealed IRM light-cured composite. Two months treatment, animals sacrificed. The extracted fixed 10%...
Methylcellulose (MC) is a chemical compound derived from cellulose. MTA mixed with MC reduces setting time and increases plasticity. This study assessed the influence of as an anti-washout ingredient CaCl2 accelerator on physical biological properties MTA.Test materials were divided into 3 groups; Group 1(control): distilled water; 2: 1% MC/CaCl2; 3: 2% MC/CaCl2. Compressive strength, pH, flowability cell viability tested. The gene expression bone sialoprotein (BSP) was detected by RT-PCR...
