A computerized literature search was performed on March 1, 2016, in MEDLINE, PubMed, and COCHRANE LIBRARY for data published from January 2011 to March 2016. Composite. First Impression Dental. It may be concluded that good sealing ability of biodentine along with its favorable biological properties show that materials can be used competently in clinical practice as a retrograde filling material. Survival analysis was performed using the Kaplan-Meier, log-rank, Chi-square and Fisher’s exact test, respectively. Immunohistochemistry studies revealed that nanostructured materials induced proliferation of hepatocytes, but that the immunological response to the materials was not strong enough to induce proliferation of immunoreactive cells in liver in the observed time period. Direct pulp capping (DPC) is considered a way to enhance pulp healing and induce reparative dentin. Tandlakartidningen.

The aim of the study was to evaluate the reparative capacity of Biodentine™ (BD), TheraCal® LC and TotalFill® as DPC materials and to assess dentin bridge formation. Introduction: Bosso-Martelo R, Guerreiro-Tanomaru JM, Zhang W, Li Z, Peng B. Ex vivo cytotoxicity of a new calcium silicate. Aim Primary molars were restored with the compomer material, and permanent molars were restored with the resin composite material. USA.gov. Of these, four studies compared the biocompatibility and eight compared the sealing ability. repair cement iRoot BP Plus with primary human osteoblasts. The success rate was 69% for CH and 93% for ProRoot MTA (P < .05). conventional root perforation repair materials. The rate of gas permeability by Leak detector-Edwards LD 416 was measured in all teeth. Note the cytoplasmatic extensions intimately adhering on the cement surface (scale bar = 20 m) (from the authors' collection), a) Radiographic view of the teeth immediately after trauma, b) Radiographic view after 2 months; c) Radiographic view after 4 months of calcium hydroxide dressing, d) Radiographic view after 6 months of calcium hydroxide dressing, e) Odontometry of the first upper right incisor, f) Odontometry of the first left upper incisor and second upper right incisor, g) Definitive obturation of the injured teeth with MTA Angelus, the application of root canal sealer and guttapercha; h) Radigraphic followup after 6 months of MTA angelus treatment. Restor Dent Endod. no. hPDL fibroblasts were plated at a density of 5 × 10³/well, and were incubated for 24 hours with 1:1, 1:2, 1:4, and 1:8 dilutions of eluates. Figure 2.

Significant differences in the percentage of cytotoxicity between diluted and undiluted extracts between all tested materials after 24 h and 7 day were noticed (p < 0.05). Conclusion There was a clear “top-down” remineralization in the groups BIO and MTA, and “bottom-up” intrafibrillar collagen remineralization in EXP. Transverse microradiography nanoparticulate cement in primary human mesenchymal cells. Materials and Methods Adhesive light-curing increased temperature in all groups with higher mean temperatures in groups with chemically-cured as compared to those for the light-cured glass ionomer liner. 109 scientific articles were filling material: A systematic review. The aim of this in vitro study was to evaluate the biocompatibility of newly proposed root-end filling materials, Biodentine, Micro-Mega mineral trioxide aggregate (MM-MTA), polymethylmethacrylate (PMMA) bone cement, and Smart Dentin Replacement (SDR), in comparison with contemporary root-end filling materials, intermediate restorative material (IRM), Dyract compomer, ProRoot MTA (PMTA), and Vitrebond, using human periodontal ligament (hPDL) fibroblasts. All canals were instrumented using hand and rotary files in step-back technique and copious irrigation of 1%NaOCl. The surface roughness of both cements was affected when exposed to HBSS (P<0.001 for both cements) and saline (P<0.001 for both cements).

Maintaining pulp vitality is a major objective in restorative dentistry. A positive sensibility test, a negative percussion test, the absence of swelling and discomfort were considered as treatment success. Sixty-four permanent teeth were randomly divided after caries excavation into 2 groups: CH and MTA (n = 32 in each group). "Pollutant" means any substance, radioactive material, or heat which causes or contributes to, or may cause or contribute to pollution. All four restorative materials induced mineral gains regardless of the protocol for caries lesion, without significant differences between materials. After exposure, hemostasis was obtained and the pulp-capping agents BD, TheraCal LC and TotalFill were applied. MTA proved better than CH in terms of both success rate and pain intensity. HHS All samples were composed of round and needle-like particles equally distributed with Ca/Si ratio ~2.7 at%, with the presence of hydrated calcium silicate phases. 2018; 43:e24. Curing conditions affected the surface roughness and microstructure of the cements. Microhardness Biodentine pulpotomy in mature permanent molar: A case report. Methodology Pulp capping materials caused a slight temperature decrease.

Simulated caries lesion Although further This study aims to assess the treatment outcomes of direct pulp capping with a calcium silicate cement (Biodentine) after caries excavation. A total of 245 teeth of 226 patients diagnosed to be clinical healthy or showing spontaneous pain were directly capped. MATERIALS AND METHODS In Vivo Toxicity Test The ZOE and HN cements were tested with powder to liquid ratios of 1.55 and 4:1, respectively, to allow injection under the neck skin of 35 male Wistar rats with a weight range of 270 to 350 g. A half century later, glass-ionomer cements began to suppress it Int J Dent. Significantly lower pain scores were reported in the MTA group (6.3 ± 9.5) compared with the CH group (18.5 ± 20.8) after 18 hours. The samples were demineralized, sectioned, stained, and histologically graded. J. in ebook Verlag, Berlin-Heidelberg. Biodentine shows a tendency toward the lowest marginal gap at the cement-to-dentin interface. The evaluation of the treatment was carried out by sensibility and percussion testing and by the patient’s questioning. calcium-enriched mixture cement on the strength of bovine root dentin. Eighteen Guinea pigs were used for intramuscular implantation, as teflon tubes with freshly prepared materials were placed into intramuscular pockets. Increase in L929 cells proliferation was noticed in case of undiluted eluates of ALBO-MPCA1 and ALBO-MPCA2 after 7 day (p < 0.05). In the first experimental group teeth were obturated using different sealers: Gutta Flow (Roeko), AH Plus (DeTrey), Acroseal (Septodont) and mono gutta-percha cone (10 canals each). The outcome of periapical surgery has been directly improved with the introduction of novel material formulations. ability of mineral trioxide aggregate flow. Chapter: Composition and setting reaction. Development, Grant no. Statistical analysis was performed using parametric (ANOVA and t test) and non‐parametric tests (Kruskal‐Wallis and Mann‐Whitney U test) depending on data distribution.
