Glossary entry (derived from question below)
Italian term or phrase:
semiarcata, emiarcata
English translation:
hemiarch/hemi-arch
Italian term
semiarcata
This comes from the description of the reconstruction of the dentition of a rare fossil shark (though I suspect it's no different in dentistry in general):
"Alla fine Kent giunse alla conclusione che la fila funzionale del Parotodus benedeni consisteva in 54 denti, con 14 denti nelle semiarcate della mascella superiore e 13 in quelle della mascella inferiore."
On the 'net, in addition to "dental arch" (lots of hits) there is a handful of resuls for "semiarch" and "hemiarch" (w/ or w/o hyphens). I'm not convinced enough of either of them to use it. Is that the proper term -- or is there another?
Perhaps -- and here I'd be interested in opinions -- the "semi-arch" isn't even important. If there are 54 teeth in all, there are 28 in the upper jaw and 26 in the lower jaw, and that might take care of it. Any special (medical, scientific) reason to report by "semi-arch"?
Thanks.

il termine corretto italiano e' emiarcata, NON semiarcata

un'alternativa e' di usare lower/upper hemimaxilla, rigirando un po' la frase, ma hemiarch is perfectly fine and correct.

Il motivo per cui si parla di emiarcate deriva dalla numerazione attribuita ai denti, in base alla quale il cavo orale è suddiviso in 4 quadranti (2 simmetrici sup. e 2 inf.). E' una convenzione che si rispetta.

scusa, speculari, non simmetrici.

upper/lower jaw
moreover the 'hemiarch thing' can have a function in mammals since the tooth composition is very variable and it can be easier to describe it by exploiting the simmetry of the dental pattern ...
see
http://en.wikipedia.org/wiki/FDI_World_Dental_Federation_not...
instead among the continuous growing shark teeth the principal differences are between the upper and the lower jaw...
so the reason to shorten the description by dividing the jaw in two halves vanishes.... :)
and as you can see, speaking about shark teeth, upper and lower jaws are the most used terms
http://www.google.it/search?num=30&hl=it&safe=off&q=shark te...
(also, I wouldn't use mandible/maxilla and instead prefer upper/lower jaw since sharks are the first vertebrate to develop a real mouth... i.e. the first Gnathostomata and well... two multiple rows of evergrowing teeth are not so close to our full differentiated dental composition of the maxilla and the mandible... ;)))
