“Sealed surfaces and surfaces fin- ished solely by a matrix were approx- imately 10 times less rough than after other finishing procedures. “The sealer failed to cover the whole composite surface. The unfin- ished and sealed surfaces lost their shine three to seven days after place- ment in the mouth.”* Directa’s CoForm matrix system is a unique set of pre-formed trans- parent matrixes made of celluloid plastic that are specifically designed to deal with composite restorations around difficult incisal edges and tooth fractures. The matrices conform easily to the patient’s dentition to provide a natural-looking restoration. They are applied over the cavity after etching and bonding with a slight movement to avoid air bubbles. When securely in place, exces- sive composite material should be removed. A prime benefit of utilizing CoForm is that the device aids pres- sure to force composite material into cavities and etched tubes. There is little waste involved when using CoForm compared to using disposable matrices. Light curing is carried out through the transparent surface of the CoForm matrix. CoForm’s convenient ready-cut mesial and distal corners do not adhere to composite so that they are very easy to remove without causing any drag after the restoration has been light-cured. The product is available in four sizes to accommodate almost any clinical application: canine, anterior and first molars. Packaging is a handy clinical dis- penser with a simple size selection system to find a suitable form, thus providing ease of use for the clini- cian.

A recent study published in the Journal of Dentistry conclud- ed that Pulpdent Corporation’s Embrace™ Pit and Fissure Sealant had the longest lasting antibacte- rial activity of those studied. The study, “Antibacterial sur- face properties of fluoride-con- taining resin-based sealants,” was conducted at The University of North Carolina at Chapel Hill School of Dentistry. The aim of the study was to determine the antibacterial prop- erties of three resin-based pit and fissure sealant products. The sealants were tested in both an agar diffusion assay and a planktonic growth inhibition assay using Streptococcus mutans and Lactobacillus acidophilus. Embrace retained antibacterial activity against both bacteria over time. While all the materials tested were capable of contact inhibition of L. acidophilus and S. mutans growth, the authors concluded that Embrace had the longer last- ing antibacterial activity when in solution, especially against S. mutans.
