A Pilot Study Testing A Proprietary Sealant For Plaque Reduction, Jennifer Rowland
A Pilot Study Testing A Proprietary Sealant For Plaque Reduction, Jennifer Rowland
Loma Linda University Electronic Theses, Dissertations & Projects
Enamel demineralization due to increased plaque accumulation is a well-recognized problem associated with fixed orthodontic appliances. The purpose of this study was to evaluate the efficacy of a proprietary product to be marketed by 3M Unitek for the reduction of plaque accumulation and thereby reduce enamel demineralization.
Sixty four bovine teeth were divided equally into an untreated control group and a group treated with the proprietary sealant product. Both groups were subsequently immersed in a Streptococcus mutans culture. Plaque deposits from each group were removed, suspended in trypticase soy broth, serially diluted, and plated on trypticase soy agar at 1, …

In Vitro Plaque Formation On Orthodontic Resin Sealants, Leland W. Pack
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study was to examine in vitro plaque formation on sealant coated enamel. The plaque growth on different types of sealants placed on enamel was compared to each other and to an unsealed enamel control. The antimicrobial properties of sealants were also studied.
Sealant coated bovine enamel disks were immersed in a S. mutans culture medium for four days. The amount of bacterial plaque formation was quantified by removing the deposit, suspending it in solution with subsequent serial dilution. Aliquots of the dilutions were then spread on blood agar plates and incubated for 48 hours. The number …
The Lasting Antimicrobial Qualities Of Three Root Canal Sealing Materials : Grossman's Sealer, Rickert's Sealer, And N2 Permanent, Lee R. Ingersoll
The Lasting Antimicrobial Qualities Of Three Root Canal Sealing Materials : Grossman's Sealer, Rickert's Sealer, And N2 Permanent, Lee R. Ingersoll
Loma Linda University Electronic Theses, Dissertations & Projects
An in vitro study using polyethylene tubes filled with Grossman's sealer, Rickert's sealer, and N2 permanent was conducted over a six month period in an effort to determine their lasting antimicrobial properties against eight different microorganisms.
From the study it was observed that N2 permanent possesses a long-lasting antimicrobial effect, but this effect appears to diminish greatly with time. Further investigation is needed to determine whether or not the effect is actually permanent in nature. The N2 permanent was also shown to have broader antimicrobial effectiveness against the eight microorganisms tested. N2 permanent produced zones of inhibition against five of …
