Data about application of chlorhexidine as a periodontal irrigant – Systematic Review.

Introduction. The most commonly used lavage solution for periodontal irrigation are diluted antiseptic solutions, the most important of them, is chlorhexidine solution. The ability of chlorhexidine to be fixed for periods of time of 8 hours on the surface of the tooth is among the main characteristics of the mechanism of action of this solution. Aim of the study. The aim of this study is to reveal the latest news about the indications for the application of chlorhexidine in cases of periodontal pathologies. Material and Methods. The electronic search to complete the purpose of the study was carried out on PubMed website for the last 3-year period, using the selected key words. Results. Based on the analysis of 32 articles extracted from the literature, from the combination of the key words chlorhexidine and endodontics and periodontics, not antibiotics, not probiotics, it was noticed that only 1 article was not included in the scope of our study. Conclusions. For chlorhexidine as a periodontal solution, the effects are known mainly in the control of bacterial plaque, but it is believed that new ways or different systems of its release should be found to express the periodontal effect. The side effects of chlorhexidine as a periodontal irrigating solution are better known, but in the processed data no concrete conclusions emerge as to which concentration of chlorhexidine would be the most indicated for specific periodontal diagnoses.
