The depth of the lingual fossa in permanent maxillary incisors of Norwegian Lapps.

The depth of the lingual fossa in permanent maxillary incisors of three groups of Norwegian Lapps was measured. No statistically significant sex differences or group differences were found. The assembled weighted estimates for lingual fossa depth of three groups of Norwegian Lapps were for I1 sup: 0.44 mm and I2 sup: 0.30 mm. Mean lingual fossa depths in Norwegian Lapps clearly fall within the Caucasoid range.
