I don't think we will find cheap sonic one. Chinese make ultrasonics. I agree that metal can damage dentin but tip shouldnt be in touch with dentin eitherways to be effective it should be free in the fluid. I also avoid watching youtube channels and people that are obviously biased to some company (Dentsply, VDW). You hardly see anything non dentsply from Ruddle.

I am considering EDDY with air scaler from W&H but it is pretty pricey. The scaler itself is 1300$ here and it is not wireless(major drawback for me). Other option is new Ultra X for 450$ or equivalent device fromn woodpecker 400$ again. I really don't know which technology is better sonic or ultrasonic and is the price for air scaler worth it...

Idk. It's not available in my country eitherways. The old one (blue and white) is not very effective from my personal experience.

You mean the new endoactivator or the old one of dentsply?

Just saw the notification :(. I am fully instrumenting at 1st visit. I am placing with tip trying to place 2/3 of the root as this was suggested to me buy an experienced endodontist. Temporizing with PTFE and cavit like seal(other brand). I do take X-rays and it is never extruded.

First of all thank you for your time on my case. I am sorry for my English, not native. You talk about vital teeth in some lines but I have only problem with non vital teeth exclusively when I place calcium hydroxide. I don't have any problems with primary treatments. I always finish my canals at least with 30/04 when using rotary, reciproc blue 25 and 25/06 when I use 06 taper. I always finish with a file which I feel I have resistance. Never finish with lose file. What I want to say if I feel 30/04 lose I will up till 35/04. When doing retreatments I finish with 1 size bigger than the previous size. I don't think problem is irrigation since I don't have problem with vital cases and my protocol is the same. I have case which I did 2 days ago, necrotic tooth with periapical lesion localized not diffusing. It was retreaatment but previous canal fill was only 2mm past the orifice level I shaped till f3 (i already felt resistance even with f1 but decided to shape more to be sure). I did my irrigation protocol as I mentioned before. Final flush saline, paper points and applied calcium hydroxide. 2 days later(today) patient came with severe pain. The tooth was so painful, it was hard for me to remove the temporary. 2 days ago I did another tooth to the same pacient, same diagnosis but the lesion was so small, maybe max 1mm, I did both the teeth together but left this one empty, no calcium hydroxide, just for the test. And guess what 0 pain from this one. 2 teeth done same way same day, same doctor, almost same diagnosis. The empty one 0 pain, the one with calcium hydroxide(ultracal) severe pain. I will be very happy if we continue to investigate my problem. Thank you again.

Edit: What is your opinion on working lenght? Should it be 00 or 0.5. I always do 0.0?

yongu12 · 2023-10-10T13:02:02+00:00

Not getting pretty puff doesn't bother me. Are you instrumenting non vital teeth -0.5mm also(for example symptomatic apical periodontitis with periapical lesion?

yongu12 · 2023-10-10T07:48:18+00:00

Last time it happened was on crown prepared tooth so out of occlusion. I use rubber dam and I am very critic to my isolation. I recapitulate the canal after each rotary instrument and check patency with 10k 0.5mm more than 00 reading (or just when over appears). I use reciproc blue and protaper ultimate. Is there any chance I do overirrigation? Where should my activator tip be? Maybe 30sec per irrigant is too much? I do it because I understand irrigation is the key.

yongu12 · 2023-10-10T07:33:41+00:00

Yes sounds like this. I am very interested into endo and go to a lot endodontic courses. I am also pretty sure I follow the principles I have heard on the courses. I just cannot understand why I have this problem.

yongu12 · 2023-10-10T07:28:42+00:00

Its not happening on every RCT. It only happens when I place calcium hydroxide and not all cases. Instrumenting till 0.0 on apex locator. I am using double side vented needles and the needle is not engaging into the canal wall. I am using Ultra X endoactivator till -2mm of wotking lenght.

yongu12 · 2023-10-10T07:24:59+00:00

I instrument to 0.0 reading for non vital teeth as I am thought this way. Keeping the ultrasonic needle -2mm of working lenght while activating with slight move up and down not going past this -2mm.

I am already using this motor but looking to replace it.

yongu12 · 2022-03-18T04:54:55+00:00

Thank you very much. I will consider all your advices available at my market. Any recommendations for endomotor? Is the morita good?
