Summary

Chronic periodontitis is an infectious disease of periodontal support tissues caused by bacterial biofilm, which leads to inflammation and destruction of periodontal support tissues ultimately resulting in tooth loss.In the clinic, patients with Stage III and Grade B periodontitis are difficult to gain desired outcomes on account of deep periodontal pockets, complicated anatomy, the removal of subgingival dental biofilms, and control of residual inflammation. A large number of studies have indicated that the effectiveness of local application of antibiotics as an adjunct to scaling and root planning (SRP), such as the antimicrobial and minocycline hydrochloride could affect bacterial metabolism and inhibit biofilm attachment particularly in terms of pocket depth reduction and attachment level gain. However, the use of wide-spectrum antibiotics may cause some inevitable side effects including drug resistance, pathogens and probiotics were eliminated leading to diversity of microbiota diminished, and toothstaining. To solve the problems of antibiotics in the clinic, antimicrobial peptides (AMPs) may be considered as an alternative to conventional antibiotics drugs.In this randomized clinical trial, we aimed to evaluate the effects of AMPs as an addition to SRP on clinical parameters and microbiological biofilms in patients with Stage III and Grade B periodontitis.

Conditions

  • Periodontitis

Interventions

DRUG

Oral biological antimicrobial gel

The patients were divided into subgingival scaling, and Oral Biological Antimicrobial Gel was used in the periodontal pocket after scaling. The injection probe with gel was inserted into the periodontal pocket, and the injection was slowly pushed, and the injection was gradually withdrawn during the injection, until a little gel was found at the mouth of the bag.

DRUG

minocycline hydrochloride ointment

The patients were divided into subgingival scaling, and minocycline hydrochloride ointment was used in the periodontal pocket after scaling. The injection probe with gel was inserted into the periodontal pocket, and the injection was slowly pushed, and the injection was gradually withdrawn during the injection, until a little gel was found at the mouth of the bag.

OTHER

SRP

only scaling and root planning was performed on the patient
