Introduction. Caries of teeth – one of the most widespread diseases. Most often caries amazes lateral teeth, in particular, the sixth teeth, quite often leading to the complications involving removal of teeth and loss of chewing efficiency. Prevalence studying caries defeats of contact surfaces of lateral teeth at persons of different age was the pur-pose of the present clinical research. Odjects and methods of investigation. In a current of 2012–2013 we had been surveyed 456 inhabitants of Do-netsk region of 211 men and 245 women. Patients have divided on a floor and age on two groups: in the first group has entered 221 surveyed at the age from 19 till 29 years, into the second – 235 persons at the age from 30 till 45 years. At representatives of the surveyed contingent defined prevalence of caries, an intensity index caries defeats of teeth (CSR), prevalence and an intensity index caries defeats of contact surfaces of lateral teeth. The results of the investigation and summary. It is established that prevalence of caries of teeth among all sur-veyed persons has made 100%. The indicator of intensity at persons at the age from 19 till 29 years has made 7,58±0,68, thus given indicator at men was a little above, than at women (7,92±0,41 and 7,24±0,28, accordingly), however differences are statistically doubtful (p‪0,05). At persons of the second age group (from 30 till 45 years) index CSR was above, than at persons of the previous group, – 8,64±0,72. At men of this age the given indicator (8,76±0,83) also was above, than at women (8,52±0,67), however also is statistically doubtful (p‪0,05). Interest results of studying of prevalence caries represent defeats of contact surfaces of lateral teeth, the aver-age index on all surveyed contingent has made 27,6±1,6%, at persons of the first age group – 25,3±1,4%, the second group – 28,5±1,8%. With the years prevalence caries defeats of contact surfaces increases (and it is quite explainable). The Maxi-mum level this indicator reaches at men of 30-45 years – 29,2±2,0%, the minimum indicator is fixed at women of 19-29 years – 24,8±1,3% Relative density destroyed caries process of lateral teeth with defeat of contact surfaces at the surveyed men at the age of 30-45 years has made 45,7±1,7%, at men at the age of 19-29 years this indicator was almost on 20% more low –26,3±1,4% (p‪0,05). At women the given indicators have made, according to age groups, 36,3±1,0% and 23,8±1,3% distinction is statistically authentic, p‪0,05 (tab. 3). Established concerning relative density caries defeats of contact surfaces of lateral teeth the tendency is repeated by results of the analysis of indicators of total of seals and seals apropos caries cavities of II class on Black. Relative density of quantity of the cured teeth apropos caries cavities of II class on Black at men at the age of 19-29 years reaches 41,7±1,6% that almost on 14% more than at women of the same age, 27,4±1,1% (p‪0,05). At persons at the age of 30-45 years of mutual relation of these indicators the return, they do not differ almost – 31,1±1,6% and 32,7±1,6% accordingly. Summary. The results received during research, testify to considerable prevalence caries defeats of contact surfaces of lateral teeth at inhabitants of Donetsk region. Further it is necessary to conduct laboratory and clinical researches in which course it was possible to compare clinical efficiency of restoration of contact surfaces of lateral teeth in the direct and indirect way.
