[Babase] Fwd: quick tooth question

I consulted with Jordi regarding toothsites for the darting database. He
said 2 systems for assigning toothsites are widely used.  I have included
links for both.  I don't have a particular preference, except that the
second one (The one recommended by jordi) differentiates more clearly
between deciduous and adult.
So for example, Using system one, the upper right decidous M1 would be
toothsite 28, and the upper right permanent M1 would be toothsite 30,
whereas the upper right Permanent premolar 1 would be toothsite 28.

(system 1)

Using system two, the upper right decidous M1 would be toothsite 54, and the
upper right permanent M1 would be toothsite 16, whereas the upper right
Permanent premolar 1 would be toothsite 14.

Susan, Jeanne, do you have any preference? Anyone else have any input?

FWIW, jordi mentioned a third system, but that is basically what we are
already using for the toothcodes. That is why i haven't elaborated on it
here.

Cheers
Lacey

 Hi Lacey!
I'm doing well! But still looking for a job! I hope you improve your
situation, whatever is going on...



Regarding teeth positions, “sites” or notation, there are mostly 3 methods
than can be applied. The first one is the diagram you found (the Universal
numbering system)… but I think is not really very intuitive… There is a
second numeric system, more logical, where you also assign a number to a
tooth, but taking into account if that particular tooth is on the left of
right side, and lower or upper jaw… following this diagram (World dental
federation system):

http://en.wikipedia.org/wiki/Dental_notation



Both systems are numeric, but you have to add letters (Universal system) or
more numbers (WDF system) for milk teeth…



I don’t like any of these systems, although I have to use them sometimes,
especially for particular analysis. I prefer to use a more descriptive
method, more common in anthropology. As, for example, LLM1 (lower left M1 or
first molar), URI2 (upper right I2 o second incisor)… Even LM1 for lower and
LM1 for upper... Always, "I" means incisor, "C": canine, "P": premolar and
"M": molar. Capital letters is used for adult teeth and for milk teeth you
use “i”, “c” and “m”, but the same system…


Humans and baboons have the same number of teeth... so you can use any of
these notations for both...


I hope it’s clear enough!



Best,

jordi

Jordi,

       Hello! how are you?   Doing ok here, things a bit complicated right
now, But I will be ok :).   I have one more quick question for you.  I am
trying to assign 'tooth sites' for each of the teeth in the baboon's mouth.
 I found a diagram online, but can you tell me if this is the generally
accepted labeling of tooth sites?  We just need SOME numeric system.

 Thanks so much
