(1) Background: Periodontitis is a chronic multifactorial inflammatory disease associated with dysbiotic plaque biofilms and characterized by progressive destruction of the tooth-supporting apparatus. The aim of the study was to evaluate the efficacy of basic periodontal treatment depending on the interleukin-1 genotype in adult Poles. (2) Methods: Sixty subjects aged 39-64 years were examined. At initial presentation (T1), at 6-8 weeks (T2), and 16-18 weeks (T3) after treatment completion, the following percentages were recorded: surfaces with plaque, pockets bleeding, pocket depth, and change in the attachment level. During the T1 examination, the genotype for IL-1 was determined using the GenoType ® PST test. (3) Results: Thirty subjects had genotype IL+ and the other thirty were IL-. During the T1 examination no significant differences were observed between patients. The study showed an increase of all the tested clinical parameters after 6-8 weeks. This increase continued up to the T3 examination. A significant reduction in the percentage of plaque surfaces after 6-8 weeks was observed, which was sustained after 16-18 weeks for both genotypes. For both genotypes, a significant decrease in the percentage of bleeding pockets was observed at the T2 examination, which persisted through until examination T3. For both studied genotypes, after 6-8 weeks, a significant shallowing of pockets was observed. In patients with the IL- genotype, a further significant shallowing of pockets was observed after 16-18 weeks. A significant reconstruction of epithelial attachment was observed between the T1 and T2 examinations, averaging 0.55 mm in patients with the IL+ genotype, and 0.77 in patients with the IL- genotype. (4) Conclusions: The results of our study show that the IL-1 genotype, may be one of the factors affecting the healing process after non-surgical periodontal treatment in adult Poles.
