Project Report Extract of KU Leuven BIOMAT, Van Meerbeek et al., 2020
All dental adhesives tested in this study were applied according to their respective manufacturer’s instructions for use. Each tooth was then restored with composite.
The composite was light-cured for 10s on the surface and 10s on each side of the composite.
Following light curing, the restored teeth were stored for 24h in the incubator at 37°C under 100% humidity, then transferred into pre-warmed (37°C) distilled water at 37°C and stored for 6 days.
The bonded interfaces of all micro-specimens were examined for absence of enamel at the corners using the stereomicroscope.
All fractured μTBS micro-specimen pairs (dentin and composite side) were examined using stereo-microscopy to determine the mode of failure, which was recorded either as ‘cohesive failure in dentin’ (D), ‘adhesive interfacial failure’ (I), ‘mixed failure’ (M), or ‘cohesive failure in composite’ (C).
The μTBS of half of the specimens was measured after 1w storage in distilled water at 37°C (without any thermocycling), being referred to as immediate ‘‘1-week’’.
With the remaining half being subjected to 50,000 thermocycles (5°C – 55°C, with 75 seconds total cycle time) being referred as the aged ’’2-months’’.
a French laboratory, in the club of world leaders in dental bonding systems!A university study confirms the remarkable bonding effectiveness of the dental adhesive systems of ELSODENT’s BIO+ range For 25 years, ELSODENT has been an exception, the only French manufacturer of dental consumables. Relying on an outstanding R&D department, ELSODENT BIO + products, with their remarkable physico-chemical and clinical qualities compete very favourably with most well-known market standards.ELSODENT combines high-technology and sustainable development, and places innovation at the core of its strategy.From this extensive research comes a complete range of products, developed from non-degradable and potentially less toxic molecules.To demonstrate the effectiveness of its BIO+ range, ELSODENT sent its adhesive systems (HEALBOND MP and HEALBOND Max) to Pr Van Meerbeek, head of the testing laboratory of Leuven university. Micro-adhesive tests were carried out on dentin vs. leading dental market products.A complete test report is now available and we are proud to share the results with you.They show excellent adhesion values at 1 week, which are confirmed after immersion for 2 months in distilled water! All products in the ELSODENT BIO + range are formulated without addition of HEMA, TEGDMA, or endocrine disruptors (BisGMA or BPA). #dental #madeinfrance #morebiocompatibility
Bonding effectiveness of ELSODENT’s adhesives Healbond MP and Healbond Max to bur-cut dentin has been tested by BIOMAT team of Pr Van Meerbeek (KU Leuven)
