Hi RoatanMan, I was going to respond yesterday but I was busy...buying more gloves. :) For the record, I too have logged thousands of dives and I'm sure you like myself have learned many valuable lessons from our boating environment. Since we are trading barbs, I wasn't quite sure if...

Hi Stisso, The question is not whether you can or cannot dive with a crown...you can. The potential problem is whether the remaining tooth that was prepared for that crown is in a good enough condition to retain that crown during scuba diving. It sounds like your root canal was completed...

Sorry, Roatanman, I understand the reasoning for both wearing and not wearng gloves. I'm afraid that I would side with those who wear gloves or at least put them on for decents and ascents on mooring lines. I'm not going to become politically correct as to worry about those little...

Why not ask the ENT about the possibility of a round or oval window perforation (fistula)? If this occurs, there may well be a change in your perception of tinnitis. It may become more obvious in one ear than the other, etc. Symptoms would consist of vertigo, tinnitis and the loss of hearing...

So, lemme get this straight...you're a Teck/D.I.R. type and you had an inflator that you could drop...causing an uncontrolled descent. Couldn't you manually blow into your vest? Couldn't you ditch some weight? I just wanted to know cause that is exactly the same stupid sh...er....stuff that...

Hi california, Did you mean to say that the air escapes from your EAR rather than your nose? If you had a perforation in the eardrum, it would be possible for air to escape out your ear while pinching your nose. If you pinch your nose and the air escapes from your nose...perhaps you are...

The cause is actually fairly simple. The solution will vary from individual to individual. What usually happens is that the tissues surrounding the eustatian tubes can become ingorged with blood and block the free flow of air between the nasal cavity and the middle ear. This is the reason...

Some root canals can be done in one visit and some require multiple visits. It depends upon what is found within the canal. In general, if the dentist finds bleeding in all canals, it is possible to complete it on one visit...time permitting. If there is pus or other infected material within...

Hi cek88, You describe symptoms that are consistent with a partially necrotic nerve. While it may not be abscessed at this point, it will likely do so in the near future. Root canal therapy is indicated in a tooth that is hot/cold/percussion(tapping) sensitive. Will this tooth hurt you...

Hi Niko, It's not till later in this post that you indicate that the tooth is not filled. Short of there being a fracture within the tooth or a tooth that underwent past trauma, eg. orthodontia, some sort of facial trauma, I would doubt that the tooth is the culprit. You didnot say but is...

I believe that the Sudafed PE contains phenylephrine in place of pseudephredine. Phenylephrine is related to epinephrine (adrenaline). It is a stimulant type drug that can cause vasoconstriction ( and thus acts a a decongestant by shrinking the swollen nasal membranes). It can elevate the...

Why not break this post into two parts...You were diving and perhaps suffered a sinus barotrauma. That could explain the headache, sinus pain and bleeding. However...(second part)...Your report headache, sore throat, possible fever, night sweats. Now, if you hadn't been diving and got the...

Hi Esqeddy, What you've described is typical of a sinus problem. I have had patients call me with a dental emergency following their arrival at the airport. Typically, the pain starts on descent for a landing rather than ascent to altitude. They will report a toothache or tooth pain of...

Hi VeniVidi, The composition of your orthodontic appliance has already been answered correctly. Neither stainless steel nor NiTi represent an ignition or combustion hazard during diving activities. Many metals including zinc, aluminum, iron, and titanium are combustible when finely divided...

Stirling, your point is well taken. By nature we all are averse to change and fight it even when a new (and perhaps) a better idea comes around. I'm not saying that we have to immediately embrace the new idea but when somebody with this doctor's credentials makes this suggestion, we should...

It's a well know scientific fact...chickens cannot read! Er...which part of you IS a chicken? Larry

Thanks to all. I've gotten a lot of response from the article. I guess its time was due. I appreciate all the kudos from those who have taken the time to read an article, which to some might apprear rather mundane. The Scubadoc at Dive Medicine Online (Scuba-doc.com) has the article...

I.G....I have to tell you that you really made me laugh. I now have this mental image of YOU pumping really cold water into one ear (the one with the totally clean ear canal) trying to make yourself sick. Hah! Next you're gonna tell us how you practice upchucking...both into the wind and with...

Hey, TexasGabby, all ya gotta do is ask... Larry

Aw Gee! Blush, Blush. Thanks guys. Larry
