“…Composite resins have the advantage of bonding to residual coronal and root canal dentine, which may assist in strengthening the tooth [2,3] and offer an alternative technique for restoration of ETT [4]. Dual cure resin composites core materials with different viscosity are currently used within the canal for fibre posts cementation, to restore the structurally compromised ETT.…”

AbstractObjectives: Eugenol has been used in dentistry due to its ability to inhibit the growth of a range of microorganisms, including facultative anaerobes commonly isolated from infected root canals. The aim of this study was to evaluate the antibacterial activity of the experimental composites containing eugenyl methacrylate monomer (EgMA), a polymeric derivative of eugenol, against a range of oral bacteria, commonly associated with failure of coronal and endodontic restorations. In vitro composite behaviour and wettability were also studied in conjunction with their antibacterial activity.

“…Isto cria uma unidade mecanicamente homogênea (6) , a qual proporciona diminuição do risco de fratura, e quando esta ocorre se localiza em porção mais cervical da raiz, permitindo o aproveitamento do remanescente radicular. Além disto, estes pinos apresentam alta resistência ao impacto, atenuação de vibrações sofridas pelo dente, absorção de choques e maior resistência à fadiga.…”

To investigate the effects of filler contents on the bonding and physicomechanical properties of experimental dental resin cements and the correlation between them, four groups were formulated with silicon dioxide filler in the following weight percentages: A: 40%, B: 50%, C: 60%, and D: 70%. LuxaCore dental resin cement was used as group E for commercial reference. For testing bond strength, resin cements were applied to the prefabricated dental fiber posts in the artificial teeth canal and photo cured, and then the microtensile bonding strength (BS) between posts and resin cement was measured in sticks of 1 Â 1 mm 2 . For the mechanical properties, flexural strength (FS), diametral tensile strength (DTS), compressive strength (CS), and hardness (H) were tested according to the related standard. Water sorption and solubility were also determined. The results showed both bonding and physicomechanical strengths of the experimental resin cements varied to different extents with filler addition. Positive correlations existed respectively between the filler content and some mechanical properties (r FS ¼ 0.964, r CS ¼ 0.967, and r H ¼ 0.959), whereas no significant correlations were found between the filler content and the other strength values tested in this study (r DTS ¼ 0.321, r BS ¼ 0.014), neither were between bond strength and mechanical properties. The effect of filler content on mechanical properties was more influential and prominent compared to that on bond strength. It is partial to compare properties and to predict clinical behaviors of resin materials based on a single in vitro test, and comprehensive evaluation is necessary.
