hello! great case! I would like to ask You
1. What are the tips for such a conservative preparation, because when I get into the crowned tooth especially front tooth I usually must enlarge my opening to get to the chamber, otherwise I really spent a lot of time looking for it, I dont know what I`m doing wrong 😉
2. What is the name of Your RVG sensor holder so that the patient can hold the sensor having his hand outside the mouth?
3. Do You always use BC sealer nowadays, and if so if You make an endo surgery You normally retro prep and put some MTA/biodentine ?
4. What is minimal size of apical preparation to use Endovac and what You do if You are enable to use endovac?
thanks a lot for Your Videos, knowledge and effort
regards
Maciek

Thank you again for your time preparing and sharing this case. I noticed you did not mention any lubricant. Wouldn’t a lubricant working with NaOCl help during shaping and promoting efficient cleaning of the root canal?

@Joao Costa: sorry for the late reply. The use of lubricants is optional. It’s a matter of preference. Using Single Stroke and Clean or minimizing the number of strokes before wiping the file clean will help reduce the need for any lubricants. The problem with lubricants is that they facilitate packing debris as they keep the debris suspended in the canal. What’s more important is developing habits that limit strokes inside the canal. This is a concept I call Macro Debris Removal. Cheers!
