To assess handling properties of a new shade-matched dual-cure adhesive resin cement suitable for self-etching, and total-etching/etch and rinse procedures (Suglue-10, 3M ESPE, Seefeld, Germany), and its delivery system.
Ten UK general dental practitioner members of the practice-based research group, The PREP Panel, received four different shaded syringes, the novel bonding-agent, dispensing tips and instructions for use for two-months. A questionnaire was designed to evaluate current resin-based cementation usage, and to rate the presentation, instructions, dispensing, and handling of the new material. Most responses were on a visual analogue scales (VAS).
All evaluators (100%) previously used a resin-based cementation system, six (60%) also used a ‘conventional’ system. The main reasons for choice of cementation materials were ease of use and reliability. With 98 restorations placed, the test material scored similarly for ease of use to the previously used resin-based material (4.2 v 4.4 on a VAS where 1 = difficult to use and 5 = easy to use). The new material was scored ideal for viscosity, and also for dispensing and handling (4.9 on a VAS where 1=inconvenient & 5=convenient). 80% (n=8) of the evaluators stated the available shades were sufficient and 60% (n=6) used the try-in pastes. 90% (n=9) of the evaluators agreed that it was both a clinical advantage a) to use the same luting material for all indications, including cementation of zirconia restorations, and b) for the ability of the bonding agent to bond to tooth and be a silane and restoration primer. 80% (n=8) of the evaluators would both purchase the new cementation system and recommend it to colleagues.
The new resin-based shade-matched adhesive cementation material and its delivery system performed well in this handling evaluation with high scores handling and ease of use.
