A Water Damaged Dental Device Repaired And Maintained. Model: Endo Gold
One of my customers, a dentist, called me on the phone and asked to repair a dental device. It is a device that have to do with drilling teeth. It is not the original device; it is a copy of the original and operates fine. He wants it done as soon as possible.
That is the brand name and specification of this device.
He said he had it for a while and suddenly it stopped working and he wants me to check it out and get it fix if possible.
The moment I took a look at it, the fault was very obvious because if you look to the charging pins you would see a sign of liquid damage so I need to check the base first then move on to the handle.
That is the first sign of liquid damage and I am sure there are more coming up and sure enough, take a look
That is really bad because if these male charging pins are corroded I wonder how the female charging pins going to look like.
I cleaned these pins and moved on to the female connecter on the handle.
I de soldered it off board and started to clean the socket there and it was not an easy task because I needed a pocking cleaning tool that can fit inside these pins but finally it was done and I liked the outcome.
I re soldered the tiny SMD resistors and the female charging connectors back on board and it looked nice and neat.
That was a very nice sign to see, the charging light changed from green to blue the moment I put the handle in the charger and it was charging fine.
After a while the battery was getting charged and as seen on the display it was almost full. So I took it off the charger and hit the power button and sure enough it came on and I could hear the motor spinning freely and that brought a smile on my face.
I called the dentist who came really fast for pick up, liked the outcome and paid generously for the repair. He was happy that he did not have to buy a new one because they are expensive and I said to him if this machine is expensive you need to pay attention and not let any liquid come into the machine. He smiled and left the shop.
Mission Accomplished.

Mark: yes it does. I find it strange that dentists equipment faults are usually water damage since they deal with drilling teath all the time and they use liquid to cool down the drill tips. have a blessed day

A dental Endo Gold drilling device from a firm called Woodpecker. That is kind of funny to come up with a name like that!
Good job on the water damaged charging connectors! Apparently it is never easy for a dentist to keep his devices waterproof.

Albert: yes totally agree when it comes to naming such device. LOL. thanks man. the dentists are not making an effort to keep their devices away from water since they are using water to cool down their drilling devices an I am sure they can do better than that. have a blessed day.

This brings to my remembrance when I had my premolar tooth drilled by a dentist and the crevice filled with some white substance which latter fell off about a year latter.The pain came back and I went to the LORD JESUS in prayer and wonderfully I was healed and the problem never come back, this was over 20 years ago....Praise the Lord!!.Thanks for sharing Mr Waleed.

Maybe next time he brings it back for repair you might want to try a little silicone to seal the water out away from the pins.

Jim: the pins are exposed and I do not think a little silicone can protect them. the best thing is the dentist should pay more attention to water dripping on their devices when doing the drilling. LOL. have a blessed day
