When root canal infections breach the maxillary sinus floor (MSF), sinusitis of endodontic origin (MSEO) can result. This case illustrates surgical management MSEO following nonsurgical reestablishment MSF. A 55-year-old woman presented with left facial pain and was diagnosed originating from upper first molar. Despite undergoing treatment, there no evidence bony healing after 6 months. However, cone-beam computed tomographic (CBCT) scans revealed Subsequently, intervention carried out using...

This study investigated the role of extracellular deoxyribonucleic acid (eDNA) on Enterococcus faecalis ( E. ) biofilm and susceptibility to sodium hypochlorite (NaOCl).E. was formed in bovine tooth specimens cultured with or without deoxyribonuclease (DNase), an inhibitor eDNA. Then, eDNA growth formation using colony forming unit (CFUs) counting, level assay, crystal violet staining, confocal laser scanning microscopy, electron microscopy. The low (0.5%) high (5%) NaOCl concentrations also...

Purpose: This study evaluated the dentin bonding strength and biomineralization effect of a recently developed premixed calcium aluminate-based endodontic sealer (Dia-Root Bio Sealer) in comparison with existing silicate-based sealers.

Abstract Titanium is biocompatible with bodily tissues. However, the formation of ROS on titanium surfaces might have negative response activity surroundings cells. Terrein was isolated from Penicullium sp. 20135 and found to reduce effects LPS‐induced inflammation. This study examined role biocompatibility determine if it can help improve osseointegration. MC‐3T3 E1 cells were grown surfaces. The by adding directly culture media at indicated concentration. surface produced excessive...

Cancer gene therapy involves the replacement of missing or altered genes with healthy ones. In this paper, we have proposed tumor suppressor gene-carrying superparamagnetic iron oxide nanoparticles (SPIONs) for anti-cancer therapy. Thermally crosslinked SPIONs (TCL-SPIONs) were conjugated branched polyethylenimine (PEI 1800 Da) by EDC-NHS chemistry p53 plasmid DNA delivery. The morphology bPEI TCL-SPIONs (bPEI-TCL-SPION) and pDNA-loaded bPEI-TCL-SPION was measured using transmission electron...

A variety of root canal sealers were recently launched to the market. This study evaluated physicochemical properties, biocompatibility, and sealing ability a newly resin-based sealer (Dia-Proseal, Diadent) compared existing (AHplus, Dentsply DeTrey ADseal, Metabiomed).The properties tested including pH, solubility, dimensional change, radiopacity evaluated. Biocompatibility was measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. For microleakage test,...

Objective The purpose of this study was to investigate the biological effects epicatechin (ECN), a crosslinking agent, on human dental pulp cells (hDPCs) cultured in collagen scaffolds. Material and Method To evaluate ECN proliferation hDPCs, cell counting performed using optical fluorescent microscopy. Measurements alkaline phosphatase (ALP) activity, alizarin red staining, real-time polymerase chain reactions were assess odontogenic differentiation. compressive strength setting time...

This study investigated the effects of a hydrofluoric acid (HA; solution hydrogen fluoride [HF] in water)-based smart etching (SE) at an elevated temperature on yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramics terms bond strength and morphological changes.Eighty sintered Y-TZP specimens were prepared for shear (SBS) testing. The bonding surface was treated with 37% phosphoric 20°C-25°C, 4% HA or HA-based SE 70°C-80°C. In all groups, primers applied to Y-TZP. For each group,...

This study was designed to evaluate the parameters of bonding performance root dentin, including push-out bond strength and dentinal tubular biomineralization, a hydraulic bioceramic root-end filling material premixed with dimethyl sulfoxide (Endocem MTA Premixed) in comparison conventional powder-liquid-type cement (ProRoot MTA).The canal single-rooted premolar filled either ProRoot or Endocem Premixed (n = 15). A slice dentin obtained from each root. Using sliced specimen, measured,...

The present study aimed to investigate the effects of different obturation techniques on main and accessory canal filling quality a premixed calcium silicate endodontic sealer (Endoseal TCS). We also highlighted validity methods used for evaluating quality. Thirty single-rooted premolars were 75 filling. canals instrumented randomly divided into three groups according techniques: (1) single-cone technique (SC), (2) with ultrasonic activation (SU), (3) warm vertical compaction (WV). Voids in...

Abstract Aim To apply an innovative three‐dimensionally printed tooth model to investigate the efficacy of three ultrasonically activated irrigation (UAI) systems in removing multispecies biofilms from dentine samples. Methodology Three‐dimensionally teeth with a curved root canal were fabricated standardized slot apical third achieve precision fit human specimens. Multispecies including Enterococcus faecalis , Streptococcus mitis and Campylobacter rectus developed for 21 days. The canals...

Objectives: This study investigated the effect of continuous application 10-methacryloyloxydecyldihydrogen phosphate (MDP)-containing primer and luting resin cement on bond strength to tribochemical silica-coated yttria-stabilized tetragonal zirconia polycrystal (Y-TZP).Materials Methods: Forty bovine teeth Y-TZP specimens were prepared.The dentin embedded in molds, with one side exposed for cementation specimen.The specimen was prepared form a cylinder diameter 3 mm height 10 mm.The bonding...
