An excavation of a part of the graveyard of St Olav's church, Trondheim, Norway, uncovered 389 tombs from the medieval period (1100-1600). Radiographic examination of 140 skulls with an intact premaxilla revealed hyperdontia in the form of a mesiodens in two (1.4%) cases. This is within the same range as similar medieval and present Nordic populations. Change in functional pattern does not seem to influence the prevalence.
对挪威特隆赫姆圣奥拉夫教堂墓地的一部分进行发掘,发现了389座中世纪时期(1100 - 1600年)的坟墓。对140具上颌前部完整的头骨进行射线照相检查后发现,有两例(1.4%)出现了正中多生牙形式的多生牙。这与北欧中世纪和现代类似人群的情况处于同一范围。功能模式的改变似乎并未影响其患病率。
