Welcome to What I Wish I Knew by Dental Head Start. This is a podcast where we learn from people that have been there, made the mistakes, learnt the lessons and have developed into the accomplished dental professionals they are today.

It’s your weekly mentoring session.

Hosted by Haydyn Bathurst

In dental school, taking PAs in endodontics has been incredibly fiddly. It really puts patients through the ringer trying to catch that apex when you missed it the first time. How should we be taking PAs, how many should we be taking, can I just use my apex locator instead? These are questions we’ve been dying to have a clear answer for, and if you’ve thought the same thing this episode is for you. Joining us again is Endodontist Associate Professor Ha to help give a resolution to this.

Going from zero to 1 in implant placement can feel like a quantum leap. We learn just enough at university to know that we don’t yet know enough, then spend crucial years solidifying the basics of dentistry. But where do you turn when you’re ready to start your own implant placement?  After years of learning theory, David was ready to go down this path and he was supported by Moredent, MGuide and the DIA courses including Live Surgery in Guatemala in July 2023. This has allowed David to not only go from zero to 1, but from zero to 30 and feel comfortable with each progression.  

If you want to begin your journey into implants, or you simply want to utilise a world class surgical guide and clinician support, then go to dentalheadstart.com/moredent to find exclusive DHS discounts and pathways to implant success. Or reach out to David directly to get his opinion on which steps you could take.
