The limited value of three pathogen species in predicting healing of periodontal pockets.

Baseline level of Actinobacillus actinomycetemcomitans has been suggested as being predictive of periodontal treatment outcome. We analyzed the presence of Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, and Prevotella intermedia in 55 deep periodontal pockets of 29 patients (18 men, 11 women, 37-75 years) before and after periodontal treatment. At baseline and after treatment, 62% and 33%, respectively, of the subjects presented with 1, 2, or a combination of all 3 pathogens.

Trace and heavy metal analyses of a skeletal population representing the town people in Turku (Abo), Finland in the 16th-17th centuries: with special reference to gender, age and social background.

The Julin site in the city of Turku, Finland, was excavated in 1964, 1983-1985 and 1987. On this site are the remains of the church of the Holy Spirit with its cemetery. The burial period of the excavated skeletons lasted most probably from the 1580s to the 1650s.

The relation between tooth eruption and alveolar crest height in a human skeletal sample.

It is commonly assumed that alveolar crest height increases with continuing tooth eruption unless affected by marginal inflammation. To test this hypothesis, the relation between eruption and alveolar crest height was examined in skulls from a sample consisting of the remains of 244 individuals from the late medieval period. The mandibular first and second molars and second premolars were analysed.

Dental studies of a Finnish skeletal material: a paleopathologic approach.

This paper reviews a series of paleo-pathologic studies made to investigate associations between dietary factors and development of occlusion, periodontal diseases and caries. The findings indicate that the change from hard to soft food, which has taken place during the last few hundred years, influences occlusion, craniofacial structures and oral health in several ways. Comparative studies show that the frequency of malocclusion has increased substantially.

Prevalence and distribution of dental caries in a late medieval population in Finland.

The aim was to document the late medieval material and to compare the results with findings in other medieval populations and present-day Finns. The sample consisted of the remains of 410 individuals and included 4581 permanent and 600 deciduous teeth. Age determination was based on the stage of dental development and on the attrition pattern in the molar region.
