[edit] Abnormalities?
The article said that shovel-shaped incisors are regarded as a variation, but it is under "Tooth abnormalities". Is it just a variation, or is it abnormal? But shovel-shaped incisors is a trait of sinodonty, which means that it doesn't seem to be abnormal, at least in some Asian population. --Starryboy 19:21, 21 June 2006 (UTC)
- Great question. Apparently, it is usually "abnormal" when found in non-asian and non-native american populations, and in fact most sources about oral pathology discuss shovel-shaped incisors as an "anomaly". Interestingly enough, I currently cannot find any reference to shovel-shaped incisors in my textbook on dental anatomy, but I can find it in my oral pathology textbook. It is a "variation" when found in asian and native-american populations. I had not finished expanding on that topic, but I wanted to get the sources correct to explain the topic a little more. - Dozenist talk 19:48, 21 June 2006 (UTC)
