I love your presentation thanks for sharing. Are you a specialist? I notice that there is a reasonable amount of decay on the distal of this tooth and also the premolar. I always would love to see the core buildup include all decay and remove it. Just my thoughts but I love the way you presented it and the time that you took to put this together. The final result is very nice as well on the endo. The Gradia that you placed was anterior gradia and that is radiolucent and otherwise it is wonderful case - Glenn Hi Glenn! Sorry to disappoint you guys, but no scope here. And it's out of the question for the next couple of years, unfortunately. I'm pretty sure that a scope will change my views and my skills too and, believe me, if I'd own one, I wouldn't bother to shoot freehand. Your photos are great Glenn and I appreciate your passion to video record your appointments, too, it's quite remarkable. What I'm meaning with diffraction is not related to lens, but to the tubes through the light travels. In macro photography, extension tubes get you closer, but the longer the tubes, the greater the diffraction on the tube's walls. Unless it's laser, light travels in every direction. When stack with too much extension tube, hence creating a big void with no glass elements, the light will run wild and some never make it to the sensor (loss of detail in photo). - Dan Thanks Dan ( I apologize for the Don reference by mistake in the last post). The main issues with scope photography I believe are light (not enough of it) and also depth of field which is limited by the scopes optics. You can change as much as you want the aperture on the camera but it will not make much of a difference to depth of field. You can put an iris on the adapter connecting the camera to the scope that helps some, or a dual iris diaphragm on the scope itself which helps gets the light more parallel to the adapter and helps with the photography. In any event, you should still look at a scope , a Seiler 202 can be had for 4500 or so, and although I dont believe you could hook up your cameras to it, this would help alot with any molar endo. In any event, enough scope preaching....as mentioned I like your PDF and the photography through the scope requires way less time as you just press the shutter on the scope and you dont have all the headaches of getting the camera, focussing etc. Simple press the shutte and you move on. Allows you to take lots of photos with ease of many many things. Thanks for the great case, for sharing and for your clearing up the issue with the photography with Gary.....I knew that he thought it was on the scope. I just wanted to clarify it. - Glenn Congratulations Dan!!! Nice healing. I just think you enlarged a bit too much, donīt you think that could leave the tooth weak? - Rodrigo Cunha Dan: What are you shooting and what are your settings on your photos? Two of those shots come close to being two of the best I have ever seen! - gary Hi Gary! Thank you! My gear is: Canon 350D, Canon EF 100mm f/2.8 Macro USM Canon MT-24EX This lens is the sharpest lens I've ever played with and it has a fast autofocus, regardless it's a macro... The flash maybe cumbersome at first, comparing to MR-14EX, but it opens a world of possibilities. I'm still new to it, though. The settings for those clinical photos are: Shutter speed: 1/200 (I almost never change that) Aperture: f/16 (Sweet spot of this lens is near 5.6 - 8.0 but the DOF is too shallow; narrower than f/16 and the pictures become a little too soft) ISO: 100 I'm always shooting RAW, it takes me less than 10 minutes per shooting to select photos, crop, enhance exposure / colors without fear of losing quality. See attachment: cropped, rotated, sharpened and bumped the exposure a bit. This one is shot at f/20. - Dan

This time no critics, no suggestions, only congratulations.....nice stuff! would you suggest a book on learning how to do these photos?(after the book comes tke genius, no doubt :) ) - Thanks in advance, Cristina Glenn - Nope, they aren't shot through a scope. Unfortunately I don't own one, but as far as I understand how scope works, and as far as I understand photography, diffraction could be a problem and it may alter the quality. I don't know if this is avoidable or not. - Dan Cristina - Thank you :). No, unfortunately I don't have a book to recommend to you. There are the basics of the photography that need to be understood and a lot of trials and errors. If you're willing to read something I can recommend, for starters: - Dan http://photo.net/equipment/digital/basics/ http://www.thepeaches.com/photography/Basics.htm http://www.nikonians.org/html/resources/nikon_articles/other/close-up_macro/macro_1.html http://www.livingroom.org.au/photolog/tips/macro_digital_photography.php http://thedigitaldentist-site.org.uk/default.asp Rodrigo and Dan, If the canals were very large to begin with (they were) on what basis do you make the judgement of enlarged too much? This case was very well cleaned and very well done. My only concern would be the area between the MB and ML canals. I would have liked to have seen that area troughed out a bit more to check for additional anatomy - DanS Don: I have been using the scope for 10 years and get some "ok" photography (see below) through it. It is not eaay or for the faint of heart or pocket book but I wanted to make sure that Gary knew that these were not though the scope. If you do alot of endo and you like it, particularly molar endo, you owe yourself to at least look through a scope to see what you can see. It will change the way that you view the profession. With skills like your photography skills you would be able to take some nice photos through the scope. No lens on the camera is needed for most setups. There is therefore not the defraction that you mentioned.- Glenn

I agree Dan.......this was a beautifully done case but trouging like this is great with ultrasonics under the microscope , as I have done in this photo (no MM canal found though) - Glenn

Dan, you said: And it's out of the question for the next couple of years, unfortunately. How come? I'm glad I got a scope nearly four years ago now. I still have many many many reasons Not to own one, but I use a scope anyway. It completely changed my life. The best kept secret is that using a scope is just plain fun! If you want a scope, I hope you'll ignore the reasons why it's not a good time now, and just do it! I've never heard anyone that uses a scope say "I wish I had waited", or "I'm glad I waited" ;-))) - KendelG Kendel.....I totally agree with you ......scopes make endo more predictable but they are just plain fun if Dan is doing this kind of endo without it, imagine where he will be when he gets a scope!! - Glenn
Add me to the agreement group. I had to give up my dental life and my scope is one of the things hardest to let go. A young dentist from the Dallas area got it and is already doing wonderfully with it. IF you are truly committed to this level of treatment, get one now. Mine was a Seiler Revelation, Glenn's Global, Kendel's Global and I think Seiler. It is not so much which one as is is IT needs to be ONE. I don't read all the postings anymore, but found this and felt it worth another evangelist for microscopes. Keep on this forum and listen to these gifted doctors giving willingly of themselves! Good luck. - Alan Cady >Congratulations Dan!!! >Nice healing. > I just think you enlarged a bit too much, donīt you think that could > leave the tooth weak? Rodrigo Thank you Rodrigo. Yes, I'm afraid I've enlarged a bit too much. Time will tell... > I love your presentation thanks for sharing. > Are you a specialist?

THe final result is very nice as well on the endo. The Gradia that you placed was anterior gradia and that is radiolucent and otherwise it is wonderful case. Glenn Thank you Glenn. No, I'm a GP. I've noticed that decay on the distal too, but a little too late :(. Anyway, the patient will be rescheduled to solve that too. I'm aware that some Gradia colors are radiolucent... still can't figure it out why did they choose that... Anyway, I was using Gradia-CV, I just love the saturation that it provides to teeth when placed as dentin. As far as I know, they don't make CV in a radioopaque flavor. The pdf is easy to make, as long as a template is available ;) - Dan
