在对许多早期人群的调查中，龋齿的发生率低于10%（3,5）。在斯堪的纳维亚半岛的各种中世纪材料中，龋齿个体的频率在40到60 Ufo之间（4,10,13,19）。因此，在中世纪，龋齿的发病率明显低于斯堪的纳维亚国家的现代人。然而，在挖掘出的材料中记录龋齿据说会受到特殊错误的影响。因此，据报道，死后缺陷的发生产生了错误的龋齿频率（5,18）。然而，其他研究者认为，这是很可能区分人工制品和真正的龋（13,14,19）。维生素内缺失的牙齿是否会影响颅骨材料中龋齿频率的值，这一问题引起了许多研究者的兴趣。因此，MELLQVIST和SANDBERG（13）将缺维生素的牙齿归类为蛀牙，而可以排除其他原因，如“老年性萎缩、脓漏、外伤、牙髓磨损后感染、嵌塞或牙齿发育不全”。BRINCH和MOLLERCHRISTENSEN(4)也指出，在描述龋齿发生率时，必须考虑牙齿缺失维生素的频率。HARDWICK(8)在对早期英国人群的研究基础上提出，当蛀牙比例低于5个Ufo时，缺失的牙齿中有25个Ufo可能是由于蛀牙而缺失的，而当蛀牙频率在5-20个Ufo时，同样的原因缺失了33%。SW ARDSTEDT（19）分析了牙齿的原因
In investigations of many early population groups, the frequency of carious teeth has been shown to be less than 10 % (3, 5). In various medieval materials in Scandinavia, the frequency of individuals with caries has been between 40 and 60 Ufo (4, 10, 13, 19). Thus, the incidence of caries during the Middle Ages has been shown to have been clearly less than that in modern man in the Scandinavian countries. However, the recording of caries in exhumed material has been stated to be subject to special sources of error. Thus, the occurence of post-mortem defects has been reported to yield an erroneous frequency of caries (5, 18). However, other investigators consider that it is quite possible to distinguish between artefacts and real caries (13, 14, 19). The question of whether teeth missing intra vitam can affect the values for the frequency of caries in a skull material has interested a large number of investigators. Thus, MELLQVIST & SANDBERG (13) have classified a tooth missing intra vitam as carious when other causes, such as "senile atrophy, pyorrhoea, trauma, infection after abrasion to the pulp, impaction or underdevelopment of teeth" could be excluded. BRINCH & MOLLERCHRISTENSEN (4) have also pointed out that consideration must be given to the frequency of teeth missing intra vitam in describing the incidence of caries. On the basis of his studies of an early British population, HARDWICK (8) has suggested that 25 Ufo of the missing teeth may be expected to have been lost on account of caries when the proportion of carious teeth is below 5 Ufo and 33 % lost for the same reason when the frequency of caries is 5-20 Ufo. SW ARDSTEDT (19) analysed the cause of the tooth
