Comparative Analysis and Mutual Relations Between Mariginal Periodontitis and Periapical Lesions – Literature Review

摘要

Abstract An analysis is presented of the relation between cases of low and medium advanced periodontitis and apical periodontitis. The systemic and local effects of the above are discussed. Both phenomena are caused by bacterial infections; therefore, inflammation is a predominant symptom. Oxidative stress occurring in these cases recedes after treatment. In the case of apical periodontitis, the correlation between the reduction of oxidative stress markers in serum and endodontic treatment is visible after 90 days. Polymicrobial synergy is very important in the context of connections between apical periodontitis and chronic periodontitis. Cooperation between particular bacteria species significantly increases their virulency. Porphyromonas gingivalis and Filifactor alocis are examples of such cooperation, as are Aggregatibacter actinomycetemcomitans and Streptococcus gordoni. Pathways of communication between the dental pulp and periodontal tissues are known; however, cases of their infection (even in advanced stages of periodontitis) are rare. The complicated structure of the dental pulp and its abilities for regeneration and repair might be of key importance in treating combined periodontic-endodontic lesions.
