“…Therefore, an antibacterial monomer -MDPB (12-methacryloyloxydodecyl pyridinium bromide)-, which is a quaternary ammonium compound with a methacryloyl group, has been added to the formulation of the primer of an experimental self-etching primer adhesive system (ABF; Kuraray Co., Ltd., Osaka, Japan) (5). By co-polymerization of MDPB with other monomers, the antibacterial agent is immobilized in the polymer matrix and inhibits bacterial growth on material surface by means of non-released immobilized bactericidal agents (6).…”

Morphological characterization of the tooth/adhesive interface

The purpose of this study was to assess the morphological characteristics of the tooth/adhesive interface using different adhesive systems in MOD restorations under scanning electron microscopy (SEM). The tested hypothesis was that the morphology of the bonding interface would vary in different areas of MOD restorations for the three adhesive systems. MOD cavities were prepared in 12 sound extracted human third molars and restored with Filtek Z250 composite resin and one of the following adhesive systems: Experimental ABF (n=4), Clearfil SE Bond (n=4) self-etching primers and Single Bond etch-and-rinse adhesive system (n=4). After 24-h storage in distilled water at 37ºC, teeth were sectioned and prepared for SEM. The interfacial morphology varied depending on the adhesive system and also on the evaluated area. The null hypothesis was accepted because the morphology of the tooth/adhesive interface reflected the characteristics of both the dental substrate and the adhesive systems.

“…Nevertheless, a gap-free interface seems more important in preventing secondary caries than the release of fluoride or other substances such as 12-methacryloyloxydodecylpyridinium bromide (MDPB) [29,30] from materials alone [58,64] or the bioactive intrinsic potential of the adhesives [28].…”

Luting materials for fixed prosthesis must fulfill special requirements in order to retain indirect restorations and fully maintain the integrity of abutments. The main requirements (inhibition of plaque accumulation, sealing of interface, possible antibacterial effects, acceptable solubility, wear, mechanical properties, adhesion, radiopacity, film thickness, type of curing, esthetics, storage, and cost) are reviewed to update clinical criteria on the selection of suitable materials. It can be concluded that there is no ideal luting material on the market. Alleged improvements in the physical data of newer materials do not necessarily result in better clinical performance. Only clinical trials can confirm the assumed benefits of materials.

“…The bond strength to enamel was clinically acceptable for orthodontic brackets, but was not effective on dentin. A new monomer, methacryloyloxydodecylpyridinium bromide, was synthesized, and investigated as an antibacterial agent [9][10][11][12][13] . Composite material containing the monomer inhibited the growth of S. mutans, and no elution of the antibacterial agent was observed from the material.…”

Study on antibacterial dental resin using tri-n-butyl(4-vinylbenzyl)phosphonium chloride

et al. 2011

The antibacterial properties of a polymeric phosphonium salt were studied to determine its suitability as an additive to develop an antibacterial dental resin. The phosphonium salt monomer studied was tri-n-butyl(4-vinylbenzyl)phosphonium chloride (VP), and acrylic acid (AC) and methacryloyloxyethyl trimethyl ammonium chloride (MA) were used as controls. The antibacterial activity of these monomers and their corresponding polymers (PVP, PAC, and PMA) against Streptococcus mutans (S. mutans) was examined. When incubating S. mutans in a medium containing 10 µmol/mL for 24 hours, the antibacterial activity of PVP against S. mutans was high, while the antibacterial activity of PMA and VP was lower. AC, PAC and PMA exhibited the lowest antibacterial activity. The mechanical properties of the copolymers of methyl methacrylate, 2-hydroxyethyl methacrylate, and VP decreased as VP content increased, and were lower than those of poly(methyl methacrylate).
