Local Periodontal Therapy with Subgingival Controlled Release of Chlorhexidine - A Case Report
Harnack, Lutz / Gonzales, José / Meyle, Jörg
A 47-year-old patient presented at the Department of Periodontology of our Dental School with severe chronic periodontitis. Periodontal examination revealed probing pocket depths (PPD) and clinical attachment loss (CAL) of more than 10 mm in several teeth. A total of 28 teeth were present, with 26 teeth showing PPD > 5 mm with bleeding on probing (BOP). Molars presented with furcation lesions class I and II. Additionally, poorly contoured restorations were present. Oral hygiene instructions and motivation were performed in order to reduce the plaque and papillary bleeding indexes. Subsequently, and prior to scaling and root planing (SRP), a subgingival controlled release of chlorhexidine (PerioChip®) was performed on all teeth with PPD > 5 mm for a total of 10 days. Afterwards, a full mouth SRP was conducted by a experienced dental hygienist. Periodontal parameters were assessed again after four weeks and three months.
