Diagnodent?

Diagnodent?

Looking for a new dentist. (I'm sorry I'm too far away from SB!) I see a
couple advertising the use of something called a Diagnodent for detecting
decay. Is this a true advance, or is it hyped up? Can this actually help
detect decay underneath composit fillings?

Think Amatus has one, there are others here that also have this
instrument IIRC.

Perhaps they will chime in.

Re: Diagnodent?

The DiagnoDent is useful for "staging" decay on teeth that do NOT already
have a filling. If there is a filling on the tooth, the DiagnoDent does NOT
help much. It's best use is to give a numerical value to some early decay
between teeth or in the center of a tooth, then compare the numerical value
at subsequent visits. This way you can tell if the lesion is changing or
not. I does help you make you decision of borderline lesions that you are
not 100% certain need a filling. A high number on the DiagnoDent will
indicate the need to fill the tooth soon.

It is a nice way of "staging" decay.

Now back to practicing Chords.

It takes at least 3 notes to make a chord.
(can you do that on a violin ?)
Two disparate notes are called an 'interval'.

Certainly arpeggios are well within the range
of your stringed instrument, but that's another topic.

Re: Diagnodent? -- OT

An instrument set-up for "country-style" playing has the bridge cut rather
flat so that 3 and 4 note chords are easy.

An instrument set-up for "classical" playing (like mine) has more curve to
the bridge and you can easily drag the bow across 2 strings at one time. If
you apply more pressure to the bow, you can depress the center string (of 3)
and play a 3-note chord with moderate effort. A 4-note chord on my
instrument is not possible without playing up on the finger-board. A 4-note
chord on a classical set-up is played as a transitional sound of blending
two 3-note chords in one bow stroke.

Many intervals are played with a second violin playing the 3rd and 4th notes
to create a 3 or 4 note chord sound to the listener. You will hear this
most of the time with music written for quartets.

Are country fiddles made with the same radius fingerboard? Classical
guitars have a flat fingerboard, but almost all other instruments
whether acoustic or electric have radiused fingerboards (though not as
curvy as violins).
Are violin bridge saddles "compensated" like guitar saddles? I
actually see this less often in classical guitars. I think it has
something to do with temperament, but I'd guess without frets you can
compensate with your fingering.
The (late) Lou Harrison wrote some music (I think he may have
transposed some of his own music from harp) for resophonic guitar with
curved frets. Some instruments are actually set up with separate frets
for each string, and they all can move. I have enough problems tuning
as it is. But learning resophonic would be kewl.

The radius of the fingerboard has no effect on the ability to bow across
multiple strings at one time, so they don't change it.

I don't know what a compensated saddle would be. A violin saddle is a small
peice of ebony at the very bottom of the belly of the instrument over which
the tail-gut extends from the tail-piece to the end-bottom. The strings
terminate at the "near" end of the tail-piece.

What is resophonic mean?

I personally find it tough trying to play with frets since I cannot
compensate the tone if the instrument goes slightly off tune while playing.

A resophonic guitar generally has a steel top with cones to amplify the
sound. It is usually played with a slide, and therefore I'd think with
altered tunings. The best known brands are National Steel and Dobro.
Here's a National:

That's one reason why they say guitarists spend half their time tuning
and the other half playing out of tune.

Re: Diagnodent? -- OT

Neat looking instrument !

At my lesson this past Saturday, my instrument was a bit less than one half
step sharp. Rather than re-tune, I simply moved my hand position a tiny bit
higher on the fingerboard. And,,,,,,,,,,, I was still in tune. {We tune to
"A" (440). My "A" string ended up a bit sharp on initial tuning up and the
other 3 strings were tuned high to match it.}

See, to a fretted instrument player, the idea of making those kinds of
intonation adjustments on the fly is mind-boggling.

Re: Diagnodent? -- OT

And, to someone who plays without frets, the limitations, on tone, with
frets seems constrictive. When playing a piece with accidentals mixed in,
it is common to exaggerate the sharp or the flat so as to increase the
difference between the tones. We might place the finger a quarter step
further away from the key signature note to make the accidental stand out
more. With my fat finger tips, this often means just tipping the finger
slightly.

Ya, but Newbie can bend his strings for microtonal effects. Not so
easy with nylon strings though.

Diagnodent cannot read through an existing filling. It is for detecting
lesions that originate from the surface of a tooth.
