Dentition pathology in residents of southern areas of West Siberia in the Middle Ages as suggested 152 from the craniological data

The research aimed at studying the dentoalveolar pathology in the residents of southern areas of Western Siberia (Belovsk and Leninsk-Kuznetsk districts of Kemerovo Region) in the early (8-10 cc. AD) and high (11-13 cc.) Middle Ages. The craniological data of the Anthropology Room at National Research Tomsk State University collected in the above areas were employed. The craniological material of the 8-10 cc. was collected in Belovsk District of Kemerovo Region in 1962 and 1971 (excavations of Kemerovo State University headed by M.G. Elkin). The material includes 36 sculls. 26 sculls and jaws (from 11 males, 10 females, 5 infants aged from 7 to 55-60) were intact enough to be studied. The craniological material of the XI-XIII cc. was collected in the border zone between Belovsk and Leninsk-Kuznetsk districts of Kemerovo Region (excavation of Kemerovo State University headed by I.M. Ilushin). The material includes 50 sculls and fragments thereof. Sampled for study were 46 sculls and jaws of 22 male, 16 female and 8 infant residents, ages ranging from 2 to 60 years. There were found minor caries lesion in the early Medieval period (11,54 %) that increased to 21,74 % in the advanced Middle Ages; considerable occurrence of parodentium pathology (42,86 % in early and 57,89 % in the advanced medieval period) and that of the dental hyperabrasion (38,1 % in the early Middle Ages, 42,11 % in the developed Middle Ages). Life-time dental loss occurred rarely in that era which accounts for the absence of secondary deformations in the early medieval period and their only presence of 5,26 % during the developed Middle Ages. Almost one third (26,92 %) of the population had dentoalveolar anomalies in the early medieval period and almost half (47,83 %) over the developed period. It was dental crowding (tooth torsion) that prevailed. Dental crowding revealed itself in 19,23 % of the population in the early Middle Ages. Acute anomalies were not found. Dental crowding occurred in 36,96 % and with more acute anomalies during the developed medieval period. Combined anomalies were also detected. Dentoalveolar pathology occurred in the early and developed periods of the Middle Ages. Population of the southern areas of West Siberia most often had parodentium pathology, dental hyperabrasion and dental crowding (tooth torsion). The tooth decay was insignificant. The spread of pathology of the dentoalveolar system increased in the high Middle Ages compared to the early Middle Ages, but no statistically significant differences were found (p>0,05). The data obtained make it possible to retrospectively assess the state of the dentoalveolar system, which is important for the disclosure of evolutionary processes in the dentoalveolar system when compared with the nature of the pathology in residents of the XXI c. This, in turn, contributes to the understanding of the etiopathogenesis and the choice of the correct tactics for the treatment and prevention of diseases of the dentoalveolar system.
