Caries prevalence and other dental pathological conditions in Vikings from Varnhem, Sweden

In a late Swedish Viking Age population dating from around 10th-12th century AD, the prevalence, distribution and location of dental caries were studied. Tooth wear, other dental pathology and anatomical variations were identified and recorded clinically and radiographically. A total of 3293 teeth were analyzed from 171 individuals with complete and partial dentitions, of which 133 were permanent and 38 deciduous/mixed dentition. The dentitions were studied clinically, using a dental probe under a strong light source, and radiographs were taken for 18 of the individuals to verify and complement the clinical caries registration. Almost half the population, 83 of 171 individuals (49%), had at least one carious lesion. All individuals with deciduous or mixed dentitions were caries-free. The number of teeth affected by caries among adults was 424 (13%) and the surface most susceptible to caries was the root surface. The tooth most commonly affected by caries was the first mandibular molar. Other findings included apical infections, which were detected clinically in 4% of the teeth, and one case of filed front teeth. The findings gave a unique understanding of life and death in this early Christian Viking community and indicated that it was common to suffer from dental caries, tooth loss, infections of dental origin and tooth pain. These Vikings also manipulated their teeth through filing, tooth picking and other occupational behaviors.

Prevalence of Dental Caries in Past European Populations - a Systematic Review

OBJECTIVE

Within the fields of anthropology and osteoarcheology, human teeth have long been studied to understand the diet, habits and diseases of past civilizations. However, no complete review has been published to collect and analyze the extensive available data on caries prevalence in European man (Homo sapiens) over time.

METHOD

In this current study, the two databases, Scopus and Art, Design and Architecture Collection, were searched using predefined search terms. The literature was systematically reviewed and assessed by two of the authors.

RESULTS

The findings include a significant non-linear correlation with increasing caries prevalence in European populations from 9000 BC to 1850 AD, for both the number of carious teeth and the number of affected individuals.

CONCLUSION

Despite the well-established collective belief that caries rates fluctuate between different locations and time and the general view that caries rates have increased from prehistoric times and onwards, this is, to our knowledge, the first time this relationship has been proven, based on published data.

Dental markers of biocultural sex differences in an early modern population from Gothenburg, Sweden: caries and other oral pathologies

Background

With the aim to study dental pathological lesions in an early Swedish modern population, with special reference to sex variances of dental caries, the prevalence and distribution of dental caries and tooth wear were determined in complete and partial human dentitions from an early modern-time city graveyard (1500–1620) excavated in Gamlestaden, Gothenburg, Sweden.

Methods

Partial and complete dentitions were examined through visual inspection and using a dental probe. Pathologies were studied, evaluated and presented by teeth and alveoli.

Results

The study population consisted of 308 individuals. A total of 4,951 teeth in adults and 1,660 teeth in children were examined. Caries prevalence in the studied population was 55% and the highest prevalence of caries was found among the adults, where 68% of the individuals had at least one carious lesion. Caries experience (DMT > 0) in the entire population was 60%, and among adults caries experience was 76%. Women had significantly higher caries experience than men (p < 0.05). Caries was most prevalent in the molar teeth and least prevalent in the incisors and canines. Significant age-related increases in tooth wear were found, and a positive correlation between wear in molars and incisors (p < 0.001). Other clinical findings were signs of apical lesions, crowding of teeth, aplasia, non-erupted canines and calculus.

Conclusions

Findings show that dental pathological lesions affected a majority of the studied population, and indicate that women were more predisposed to dental disease than their male counterparts. Results are discussed from a multi-factorial explanation model including dietary, physiological and cultural etiological factors.
