An in vitro study evaluated the effects of barrier materials on mechanical properties of a visible light-cured composite restorative. The composite was cured and aged over a widely used cavity liner (Dycal), various cements (Fleck's, Durelon, Vitrabond, ZOE B & T) and free eugenol and tested at seven and 28 days. The properties of interest were tensile stress (strength) at rupture, compressive ...

Crown reattachment is the most conservative treatment which can be used to restore fractured tooth, presumably with sufficient strength, while maintaining original contour, incisal translucency, and reducing chair time and cost.However, in case of crown fracture with pin-point pulp exposure, we should cautiously minimize the irritation to the pulp and consider pre-treatment pulpal status, choic...

Root resections were performed on 86 maxillary molars as part of periodontal therapy. The amputation sites were sealed with Dycal and amalgam. The teeth were evaluated for vitality using electric pulp testing and cold (ice) up to 9 yr postoperatively. The greatest loss of vitality occurred within 12 months. The percentage of vital teeth at 6 months was 59% and at 12 months 38%. The number of vi...

BACKGROUND Vital pulp preservation in the treatment of deep caries is challenging due to bacterial infection. The objectives of this study were to synthesize a novel, light-cured composite material containing bioactive calcium-silicate (Portland cement, PC) and the antimicrobial quaternary ammonium salt monomer 2-methacryloxylethyl dodecyl methyl ammonium bromide (MAE-DB) and to evaluate its ef...

OBJECTIVE Provisional cements are commonly used to facilitate retrievability of cement-retained fixed implant restorations; but compromised abutment preparation may affect the retention of implant-retained crowns.The purpose of this study was to investigate the effect of abutment design and type of luting agent on the retentive strength of cement-retained implant restorations. MATERIALS AND M...

The aim of this study was to evaluate and compare the antimicrobial activity and cytocompatibility of six different pulp-capping materials: Dycal (Dentsply), Calcicur (Voco), Calcimol LC (Voco), TheraCal LC (Bisco), MTA Angelus (Angelus), and Biodentine (Septodont). To evaluate antimicrobial activity, materials were challenged in vitro with Streptococcus mutans, Streptococcus salivarius, and St...
