Summary

Introduction. In the recent past there has been an increase in the number of adults seeking orthodontic treatment therefore special attention to periodontal status of these patients needs more careful evaluation. Periodontal considerations in adult orthodontic treatment are increasingly important as patients become older. The aim of the study was to assess the interrelationship between the severity of malposition of frontal teeth with periodontal health considering to age in Latvian population. Methods. The data were analyzed from a detailed crossectional study in Latvian population. Selected samples consisted of two age groups: 15-21 (n=323) and 35-44 (n=286) years old. For the assessment of periodontal health CPI scores was analyzed for upper frontal sextant. For assessment of malocclusion 2 components of ICON index were used: upper arch crowding and incisor overbite. The differences in the distribution of ICON index and CPI index between age groups were tested using Pearson χ² test. Statistical significance of the differences in the mean values was tested using t-test. Possible interaction between above mentioned indexes was tested by means of analysis of variance. Results. Upper arch crowding and incisor overbite severity increase with age was statistical significant. There was statistically significant interrelation between upper arch crowding degree and incisor overbite and CPI scores severity in the age 15-21 and was not in the age 35-44. However comparing higher degree of the crowding and overbite severity to percent of subjects with bleeding, calculus and periodontal pockets greater percents of measurements were in older group. Conclusions. 1. Severity of upper arch crowding and overbite statistically significant increased with age with remarkable increasing of periodontal problems. 2. Interrelation between severity of upper arch crowding, incisor overbite and CPI scores was statistically significant in age group 15-21.

Key words: malocclusion, occlusal indices, periodontal health.
