Title OptiBond SOLO Adhesive Has Less Microleakage Than Amalgambond Plus
Clinical Question In a healthy adult molar restoration, will the use of Amalgambond Plus or OptiBond SOLO better minimize microleakage?
Clinical Bottom Line OptiBond SOLO adhesive has less microleakage compared to Amalgambond Plus. (See Comments on the CAT below)

Found a more recent study Lombard et. al., PMID: 17624174 had been performed comparing AmalgamBond Plus to 4 other groups (Calibra, Duo Cement Plus, RelyX ARC and their effectiveness of controlling microleakage on thermo- and non-thermocycled amalgams. The study showed that the microleakage was not significantly different among the bonded amalgams was not significantly different except that DuoCement allowed more microleakage as opposed to Calibra (p<0.0001), RelyX (p<0.0001), and AmalgamBond (p<0.0001). Also AmalgamBond allowed more microleakage as opposed to Calibra (p=0.0433) and RelyX (p=0.0433). The Lombard et. al., study appears to agree with the Arias et. al., study that different bonding agents have different effects on the amount of microleakage that occurs in bonded amalgam restorations. It must be noted however that OptiBond SOLO was not used in the Lombard et. al., study so it is difficult to compare the two studies effectively.
