Introduction and objective:
Recent in vitro studies indicate that enamel matrix derivative (EMD) could modulate the growth of periodontopathogens. The aim of the presented study was an analysis of the influence of EMD on the presence of Porphyromonas and Prevotella bacteria in the periodontal pockets of patients with chronic periodontitis in non-surgical periodontal therapy.

Material and Methods:
The studies were conducted on 20 patients. The condition of the periodontium was evaluated by clinical indexes: API. SBI. PD. CAL before and 3 months after the therapy in two selected quadrants. The material was collected for investigation. The periodontopathogens were cultured and identified. Two days after EMD-scaling root planing (SRP) was applied into the pockets.

In the group of patients under investigation before the EMD application the presence of P. gingivalis was found in 6 patients and P. intermedia in 8 patients. After root planing and EMD application no periodontopathogens were identified in those patients either in the periodontal pockets treated with EMD or in the periodontal pockets free from EMD (control). In the statistical analysis of changes in clinical indexes, the application of SRP and SRP combined with EMD was proved to significantly influence the improvement of the clinical state. However, no significant differences between the individual parameters were found in either group.

The SRP is an effective method of limiting the development of periopathogens in periodontal pockets. The non-surgical therapy with EMD does not change the clinical parameters significantly, compared with the SRP. Simultaneously, the application of EMD inhibits the development of periopathogens, such as Porphyromonas gingivalis and Prevotella.
