Sealing Materials

In vitro studies have shown that rapid penetration of bacteria in the entire root canal system may occur after endodontic treatment without a coronal seal. A proper restorative technique is necessary to ensure a coronal seal and protection of the residual dental structure. The aim of this in vitro study was to evaluate the coronal sealing ability of the most relevant clinical materials by means of dye penetration (neutral red dye, Sigma-Aldrich, Germany), through a light spectrometric device, and to establish which one of the tested dental materials possesses the best sealing ability. Forty-two extracted teeth were prepared and used for this experiment; they were sealed with 5 different cements. The flow composite had the best absorbance value with 0.00675 ± 0.00096 (mean ± standard deviation) for monoradicular samples and 0.025 ± 0.00129 for pluriradicular samples. Under the constraints of the present study, both flowable and packable composite materials can be recommended as orifice sealing materials to prevent microleakage in an endodontically treated tooth. To assess the clinical superiority of any material, further in vivo studies are required.

Manufacturing Procedure

In a previous study, on healthy volunteers two purified heparin preparations, obtained from hog and beef mucosausing the same manufacturing procedure, were compared for anticoagulant activity. Heparin levels measured by anti Xa assays and AFTT were not statistically different following subcutaneous or intravenous heparin injection, (M. Aiach, A. Kher, A. Kichaud, J. Mardiguian, M. Trillou, M. Leclerc - Thrombosis Research, to be published). An in vitro study was undertaken to evaluate the biological activity of these two heparins : thrombin clotting time was performed in plasma. Anti Xa activities were compared in purified system using human antithrombin III, or in plasma, and bovine and human activated factor X were used. Residual F Xa was evaluated with chromogenic substrate and in a clotting assay. The results will be reported in detail.In conclusion, the biological activity in vitro is higher for hog mucosal than for beef mucosal heparin when evaluated with sensitive and accurate methods. The in vivo study does not confirm these data. This discrepancy between in vitro and in vivo studies could be explained by individual variation of in vivo response to heparin and by dissimilarities in the distribution of molecular weight between these two heparins.

Twist Drills

Background: The aim of this in vitro study was to analyse the primary stability of 20 implants placed with Twist drills (TD) versus 20 implants placed with Summers osteotomes (SO) and 20 implants placed with B&B bone compactors (BC) in medullary bone (quality type III and type IV). Methods: The implants were placed in 10 fresh pig ribs fixed on a bench vice in order to avoid micro-movements during surgical procedures and measure recording. Peak insertion torque (PIT) and Peak removal torque (PRT) were recorded with MGT-12 digital torque gauge and ISQ was recorded through OSSTELL ISQ™ device by an independent operator. Results: Comparing our data (Tukey test p = 0.05), it was evidenced a statistically significant difference in the PIT between TD and BC groups (p = 0.01). Analysing ISQ data, there was a statistically significant difference between the TD and BC groups (p = 0.0001) and between the SO and BC groups (p = 0.014). The analysis of PRT evidenced a statistically significant difference between the TD and BC groups (p = 0.038). Conclusions: This study evidenced that bone compactor preparation can positively influence primary implant stability (PS), however further in vivo studies and a larger sample are necessary to assess the usefulness in several clinical settings.
