Malocclusion and Dental Crowding Arose 12,000 Years Ago With Earliest Farmers

A study from Dublin University College has revealed that dental crowding and malocclusion first appeared amongst the world’s earliest farmers around twelve thousand years ago. Another interesting conclusion from the undertaking is that the hunters-gatherers who lived before the aforementioned group lacked the condition.

The findings were attained after scrutinizing the lower jaws and teeth crown dimensions of archeological skeletons dating back between six thousand and twenty eight thousand years ago. The expedition uncovered an outright distinction between the jawbone frameworks of European hunters, Anatolian semi-sedentary gatherers, and the transitional farmers.

Lead author Ron Pinhasi points out that the transition to agricultural practices resulted in the scenario because farmers were now consuming “soft” cooked edibles when initially, hunters fed on “hard” uncooked foods. The change enacted a decrease in jaw size since there was a lesser need for chewing, but the teeth’s magnitude remained and therefore the jaw was overburdened as there was no adequate spacing. Project proponents are regarding this limitation as the initial defect that precipitated malocclusion, an ailment currently plaguing around one in five persons in the global population.
