I've yet to see a crooked tooth in many years of paying very close attention. It only stands to reason that we once were part of that club too. The only crooked tooth I've seen on a "wild" animal is at Yellowstone Lake Lodge - a bear's head on display, and the malocclusion is almost imperceptible. But note, it was a Yellowstone bear - a human garbage eater for sure.<br /><br />Of course sugarcane doesn't cause cavities. Neither does fruit, grain, tubers, or other unrefined carbohydrate foods. Residue on the teeth is inconsequential, as are temporary postprandial rises in blood sugar. I'm supporting that now on my current dietary experiment. I'm not even bothering to brush my teeth as usual.Matt Stonehttps://www.blogger.com/profile/00823163098708883587noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-14389275381083857192009-10-13T14:58:26.413-07:002009-10-13T14:58:26.413-07:00Ken,
more recent orthodontic studies of Swedish ...Ken, <br /><br />more recent orthodontic studies of Swedish and Norweigian children indicate that non-nutritive sucking habits, such as digit sucking is more prevalent among females than males. It would appear that at about 18 months of age the incidence of digit sucking increases but only (with the exception of one small south-western Swedish community) among girls.<br /><br />I speculate that this has to do with societal behaviour: I.e. boys also learn to speak later than girls. Boys are generally potty trained and out of diapers later than girls. <br /><br />Possibly the needs of boys are more readily met by their caregivers than the needs of girls. <br /><br />For some reason, look at places in the world like India, Pakistan, Afghanistan, China etc. etc. and even in Europe, boys have a higher value than girls. It wouldn't be all that surprising if boy children, even in Europe, get more attention than girls. And thus have less need to comfort themselves through digit sucking than girls.Gabriella Kadarhttps://www.blogger.com/profile/18294468426599703416noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-42723582515596941682009-10-13T12:10:54.720-07:002009-10-13T12:10:54.720-07:00Hi Jon,

Sugar cane is fibrous and is probably pretty good at removing plaque, even though it's full of sugar.<br /><br />Hi Ken,<br /><br />Interesting paper. The medieval teeth had a lot of attrition. I agree with you 100% that genes influence skull shape, including width of the face. Different races clearly have their own characteristic skull shapes. I agree that the Xavante have particularly broad faces and there's likely to be a genetic component to that. <br /><br />Just a personal observation though: I've noticed that broad faces don't always travel along with broad arches. I'm no longer surprised when I see people with apparently well-developed faces and narrow, crowded arches. I took a look at a friend's arch the other day, expecting it to be broad because he has a broad and well-formed face, but it was narrow. Same with a former co-worker of mine.<br /><br />When I referred to an underdevelopment of the middle third of the face, I was talking more about the depth than width. Binder's syndrome patients have "dished" faces, but they aren't necessarily narrow overall.<br /><br />Hi Ryan,<br /><br />That's cool that they referenced my post!<br /><br />The more I learn about malocclusion and facial development, the more I agree that it affects many other things. It affects breathing, which affects posture, oxgenation, physical capacity, and influences occlusion itself. It affects chewing and swallowing, breast feeding, and probably susceptibility to sinus infection. I'm going to look up the second reference you posted, thanks.Stephan Guyenethttps://www.blogger.com/profile/09218114625524777250noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-7827648505492441702009-10-13T10:55:24.850-07:002009-10-13T10:55:24.850-07:00Good stuff, Stephan.

One facet of this condition I find interesting is the effect of malocclusion on the overall health of human beings. <br /><br />For example, an article in the WAPF journal is called <i>From Attention Deficit to Sleep Apnea: The Serious Consequences of Dental Deformities</i>. One study referenced in the article suggests that the degree of malocclusion in an individual can accurately predict intelligence levels(1).<br /><br />Also interesting is the vast difference expansion appliances can make in cases of malocclusion. A British study is referenced about a set of twins in which one twin receives palate expansion while the other does not. The difference is striking! (2)<br /><br />By the way, Stephan, did you know that the WAPF journal referenced your blog?

A comparative study of medieval skulls from Norway.</a><br /><br /> "This study indicates a significant increase in both the prevalence and the severity of malocclusions during the last 400 to 700 years in Oslo, Norway."<br /><br /> OK I am converted to the idea that a modern diet can produce malocclusion, however the paper goes on to to say<br /><br />" Furthermore, although no sex differences were found in the modern sample, females had both a higher prevalence of malocclusions and more severe malocclusions than did males in the past".<br /><br />So the malocclusion due to modern diet is obscuring the focus of the genetically caused malocclusion in Europeans. <br /><br />The sexual selection hypothesis was of selection women for feminine looks (ie small face and jaws) which carried male faces to a more feminine norm as a byproduct. That women had more malocclusion way back when suggests it was they who were the focus of selection for something about their jaws. And of course the<br />first known impacted wisdom tooth was in a woman.<br /><br />A modern diet can produce malocclusion, however I am not so sure that modern Europeans' high incidence of it is entirely due to their food.

For instance, sugar cane has significant amounts of chromium, if I remember correctly.Helenhttps://www.blogger.com/profile/14504810823521044641noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-87782065690332051062009-10-11T06:32:05.329-07:002009-10-11T06:32:05.329-07:00It seems likely it's more fruitful to ask what...It seems likely it's more fruitful to ask what's *not* there in the diet when things go wrong.<br /><br />So far as "starchy" foods go, it doesn't seem that, for example, the isolated Swiss mentioned by Price were exactly avoiding these, since rye bread was one of their staples. And they had very good teeth and well-formed faces. They did not, of course, eat bread *instead of* other important foodstuffs.<br /><br />There's an interesting article here where a dentist says when cutting he can feel how hard people's teeth are. Whenever he's noticed an extreme of hardness or softness, he asks the patient about his upbringing and diet. Those with hard teeth:<br /><br />"... were more often born and raised on farms, but also in large cities or small towns where they ate fresh-cooked and raw foods that were freshly obtained from the farm or the garden. They generally started out in life breast-fed and not bottle-fed. The milk consumed in childhood was, without exception, raw and not pasteurized."<br /><br />http://www.westonaprice.org/archive/silverman.htmlAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-61663084590418829092009-10-11T06:20:27.912-07:002009-10-11T06:20:27.912-07:00Fascinating info.

I wish my teeth were still straight. They look fine but I can tell. Chewing is very difficult -- especially the tearing apart of meat (I eat raw sometimes and have to cut it up like I'm 5). Before I went 0 carb I had jaw pain and rotting gums, no more. I'm only 32! But, if carbs cause malocclusion that is reason enough to never eat them.Marneehttps://www.blogger.com/profile/13581045023000720429noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-7937350943527622172009-10-10T20:12:31.618-07:002009-10-10T20:12:31.618-07:00This doesn't pertain to humans, but I was read...This doesn't pertain to humans, but I was reading your post while my husband was watching a National Geographic TV show that featured a zoo gorilla, and it was mentioned that she was born in a zoo and bottle fed because her mother wouldn't nurse her.
