Details

This study evaluates the combination of D-LL-31 and DNase I to eradicate biofilms of the periodontal pathogen Aggregatibacter actinomycetemcomitans. The findings demonstrate potential for developing a safe and effective mouthwash solution.

Aggregatibacter actinomycetemcomitans is a key pathogen in periodontal disease, damaging periodontal ligaments and alveolar bone through biofilm formation.

  • D-LL-31: An engineered antimicrobial peptide that exhibits superior biofilm-killing ability compared to conventional treatments.
  • DNase I: Enhances efficacy by disrupting the biofilm matrix.

Results showed that D-LL-31 effectively eradicated biofilms, and its combination with DNase I further enhanced biofilm disruption without cytotoxicity to gingival epithelial cells. This combination shows potential for development as a mouthwash to improve oral health and combat periodontal disease.
