I'm not sure if this is the right forum to ask, but what are Asian shovel teeth? Does anyone have any pictures of them? They supposedly 'curve out' . . . just what is that supposed to mean? I just can't imagine anyone having incisors like that.

You wouldn't notice the teeth of mongoloids, namely Chinese, Japanese, Koreans and Mongols, unless you were a dentist. Shovel shaped teeth refers to the incisors and the rear view of the teeth, not what you see from the front. If you can envision the shape of a shovel compared to a spade, one is straight edged and flat and other the edge is slightly curved and the inside shape is scalloped. They don't curve outwards but inwards at the rear of the teeth. There are usually plenty of pictures and drawings in biology books and dentistry websites.

Just the incisors are shovelshaped...or not they are on the back formed as shovels that means theyre slightly thicker on the both sides you can check as best on the upper second incisors...  in real life its of less obvious...but its a nice example |

there are a lot of variations of so called shovel teeth and around 3% European or so have them...may as a relict but its possible they just arent a *sign* for any race. Whatever- birthmarks like mongolian spot appear dont just in asia. Pretty many *brown* people-of every racial decent that do have. Its like all this treats. some have some have not. Unfortunly is physical anthropology a discribing science and not exact as math or so. |

I've seen quite of few whites, Western Europeans even, with shovel-like incisors (bottem as well as top), though a bit shallower than the one in the picture. I remember reading somewhere that Neanderthals had this trait.

I remember reading somewhere that Neanderthals had this trait. I've also read that some Greek Cypriots were found to have slight shovelling of one of the two incisors. Greek Cypriots are Caucasoid and almost certainly have no Mongoloid DNA above the statistical noise level, as technology currently stands. In dental models I've seen the incisors in question, the two top incisors; they are slightly pitted in the middle of their lingual (rear) side and have slightly outlined borders around the edges. My teeth are like this. This is an example of teeth without shovelling. Shovelling is very prominent borders. The detection of shovelling is useful to forensic scientists who use teeth to help identify people whose remains are destroyed. |

hum...
then mine are just like that!
I guess it depends on the magnitude of the "shoveling"

I have never looked inside any person's mouth to see the backs of their incisors. jul wrote that 3% of Europeans have shovel shaped incisors. I have never read that piece of data, but 3% is nothing. Europeans are probably 1 - 10 % mongoloid anyway, so 3% is not large.
Actually shovel shaped incisors are indicative of mongolians. In the North Chinese, shovel shaped incisors is about 93%; Koreans 90% and Japanese 85%. Compare that with Europeans:3%, from jul. From what I understood of jul's post, she was saying that the mongolian spot is not significant because many brown people of different races have it. The figures are mongolians >80%, Europeans 10 - 15 %, negroes 10 - 15 %. Since a sizeable number of negroes are some shade of brown, and a large group of European are darker than the hollowed pinkish white, 10- 15 % of European and negroes is not very significant compared with more than 80% of mongolians. Racial features are not totally limited to one racial group or sub race, but overlap to some extent. For example, epicanthic folds are absent in about 10% of mongolians. That does not mean those 10% are not mongolians or even mixed just that they missed out on epicanthic folds. However epicanthic folds are still more common in mongolians than caucasians, and is diagnostic. Nothing is perfect.
I am caucasian and I don't have shovel shaped incisors or had a mongolian spot or have epicanthic folds.

I don't know if this is normal
I have 4 upper maxilar incisive tooths (tooths betwen the canines).
the 2 middle upper incisive tooth have no middle depression only a slight curvature.
the lateral upper incisives have a little very minute depression in the midle...it's only that (any of you have this kind of tooth?)
In the lower maxilar My tooth are all straight!
no depression whatsoever.
Is this 2 upper lateral incisives depression normal in caucasians?

Graeme your's two upper lateral incisive don't have a minute depression in the back?
My mother have those kind of teeth (like mine), as my father.
They are from different regions in portugal, I guess this must be a common trait.
