Introduction. Research of effects that irregular interproximal dental restoration have on supporting structures of the teeth and examination of evolution and course of changes in tissue structure is quite a poorly studied topic.
Aim of this study is to examine and assess clinical and radiological changes in periodontal tissue caused by irregular interproximal dental restoration in particular group of patients with different age and sex.
Methods. Irregularities which were assesed in this study are divided into two groups: a) gap (cracks) occurring between dental restorations and the gingival walls in Class II cavities, b) prominence of dental fillings out of the teeth anatomical sphere, resulting with the positive step in gum third of tooth in Class II cavities. The study was based on whether in the particular forms of irregularities of the dental restorations are differences in the degree of change in the periodontal tissue, depending on the material from which the restoration is made, and the materials used were composite fillings and amalgams.
Results of this study show that irregular dental fillings significantly affect the inflammatory response in periodontal tissue. Irregularities in the form of unfilled space cause major changes in periodontal tissue. Composite fillings cause a higher degree of inflammation in relation to amalgam fillings.
Conclusion. Improper tooth fillings cause periodontal tissue damages.

Key words: irregular dental fillings, inflammation of periodontal tissue.
