Exploring the Strength of Dentine Bonding in Dentistry

What is the best bonding agent to use? Does it actually matter? Spoiler: it does! How do you get the best bond to dentine and enamel with the adhesive system you are using? Dr Sam Sherif joins us in this episode, where he discusses bond strength in detail as well as sharing his top tips in achieving long lasting adhesion for our daily adhesive Dentistry. There's a lot to learn in this one so get ready those onions ready! https://youtu.be/FICDBVljsGw Watch PDP192 on Youtube ​Protrusive Dental Pearl: Always read the directions for use - ESPECIALLY for your adhesive systems!

So when we're looking at the literature for which adhesive system or which bonding agent we should be using. Do we actually need more than 50 megapascals? Jaz's Introduction: A lot of adhesive systems will easily give you 20 megapascals. Is that good enough? It probably is. We know that adhesive density in the right environment, done skillfully, can work, and sometimes all you're achieving is 10 to 20 megapascals. However, if there are a few things that you could do in your practice, in your protocols, to reach the higher ends, 50 and even beyond, then perhaps we should consider and learn these techniques. For me, it depends on how complicated it makes your procedure. Like if it becomes really technique sensitive, so that only 10 percent of the time you're getting 70 megapascals and then 80 percent of the time you're getting like 10 megapascals, that's not predictable. That's not a predictable way of doing it. So how can we make our bonding protocols more predictable so we get a higher bond strengths more consistently. That's what today's episode is about because I asked Dr. Sam Sharif, which is the best adhesive system, which is the best bonding agent, and to tell us which generation or generations on bonding agents should we be buying. Hello Protruserati, I'm Jaz Gulati and welcome back to your favorite dental podcast. Today's a very geeky one we go into science behind the bonding and I love how Sam will break down the different generations which we've all come across a different generations of bonding systems and we fell asleep in that lecture and there's just far too many generations. But actually we make it clinically relevant and I love that he actually gives you sound advice on which generations to avoid and which generations to go for, and which bonding agents he believes in and what the literature is saying. If you're a new listener, welcome to Protrusive. It's great to have you here. If you're a returning listener or watcher on YouTube or on the Protrusive Guidance app, it is so great to have you back. You've picked a good one to re engage back into. Very clinical relevant in our daily dentistry. And towards the end of the episode, we'll actually cover little nuances and how we can actually get the higher bond strength. This episode is eligible for CPD.

Dental PearlThe Protrusive Dental Pearl I have for you is to read the instructions for whichever adhesive system you're using. Now, I've said this before, but some cool things that I learned here is that in some adhesive systems and some bonding agents, if you air abrade the dentine in something I do routinely, you are actually hindering your bond strength. Whereas with other systems,
