Dentistry is a vast area wherein you need to consider numerous factors while treating the teeth. And we know it requires more than just the expertise to manage them. It is the precise judgement or the decision to take over a particular situation, the sufficient knowledge of handling someone’s dental matters and even the right medicines or components to treat the budding problem out there. If you lack the proper understanding of the chemicals required in dentistry, how can you be sure of the effectiveness of the treatment altogether? So, here comes a brief post on the coupling agents and how they impact your actions in dentistry.
Why should or shouldn’t you use coupling agents in dentistry?
Silane coupling agents from All Chemicals manufacturing and Concentration are the organosilane compounds having around two different reactive groups bonded to a silicon atom in a molecule. The company also has a wide variety of similar chemicals required in various industries or fields. In silane coupling agents, these molecules carry two different types of reactive groups attached to the silicon atom that can react and couple to an inorganic surface such as ceramics or oxide layers on metals and even to organic resins through covalent bonds. In simple words, you can use them as adhesives in various ways in dentistry. However, the good and not so good parts of using them are listed below:
- Pro-They are one of the best fillers required in dentistry — Coupling agents are used between organic polymers and inorganic fillers to ensure resin and filler compatibility. Silane coupling agents improve mechanical properties like flexural, tensile, and impact strength and (also) electrical properties like filling volume, swelling, and water vapour penetration.
- Cons – They are short-lived – No matter which quality of coupling agent you use, they have a short life span. They tend to age early even when you store them in a bottle (and become ineffective). It is the reason you should buy them only in limited quantities for your dental clinic.
- Pros – They are an age-old theory that has worked well –For fifty years, silane coupling agents have been used in locking interfaces and making them stronger. They are even consumed in modifications of the layers or aggregating them firmly. Earlier, these were mainly utilised in plastic binding industries. But gradually, they made a mark in dentistry and are widely utilised and trusted by scientists to coat a surface of the teeth or use it as fillers between the gaps or even in shaping the structures.
- Con –They are sensitive to water – Silane is very sensitive to water, and you will see that it breaks down immediately as it comes in contact with moisture. The water gets absorbed in its composites leading to hydrolysis of the silicon bond, and you face immediate filler loss. But today, some functional trial silanes have been discovered to significantly improve composite mechanical strength by preventing water absorption and bond displacements at the fibre/resin interface.
- Pro-They are better than the inorganic compounds and fillers — Keeping in mind the poor compatibility of inorganic filler and organic polymer, surface modification of inorganic fillers contributes to improving the overall performance of the composite and increasing the binding force. Silane coupling agents improve computability between fillers and resins, increase reinforcement, alter dispersion, and reduce water vapour expansibility and penetration.
Well, silane coupling agents seem to be a fine addition to your dentistry requirements because of their unique properties and features. However, remember to use it considering its cons and take the necessary precautions so that your patients don’t have any complaints with your treatment after using this component in the procedure.
