This systematic review assesses the efficacy of local chlorhexidine (CHX) chips as an adjunct to nonsurgical scaling and root planing (SRP) in treating chronic periodontitis, compared to SRP alone. A comprehensive search strategy was developed to identify relevant studies, focusing on articles published in English. Searches were conducted in MEDLINE (via PubMed), Web of Science, and periodontology journals up to December 2020, specifically looking for studies on the use of CHX chips alongside SRP for managing chronic periodontitis. This research took place from January to September 2024. The review found that sites treated with SRP plus CHX chips showed improvements in probing pocket depth, clinical attachment level, plaque index, and gingival index. The results revealed that 48.50% of the findings were not statistically significant between the two treatment groups. In contrast, 25.75% of the findings were significant for the CHX chips group compared to the SRP alone group, while 1.5% were significant for the control group. Additionally, 24.25% of the data were unavailable. Combining SRP with CHX chips results in more significant improvements in treating chronic periodontitis.
