The teeth of modern Skolt Lapps from northern Finland are considerably larger than those of their ancestors of the Eighteenth Century. The increase is probably attributable to improved nutrition. One or more teeth, excluding the third molars, were congenitally missing in 18.8% of the population aged 5 to 20 years. Relative to a standard the anterior teeth are larger than the posterior teeth, particularly the premolars. This accords well with the hypodontia pattern which is dominated by premolar agenesis.
