Treatment of aggressive periodontitis with photodynamic therapy and ozonated water irrigation as an adjunct to scaling and root planing: A case report

Aggressive periodontitis (AgP) is a type of periodontitis which causes rapid destruction of periodontal ligament and alveolar bone and occurs in otherwise systemically healthy individuals generally of a younger age group, but patients may be older. Ozonated water strongly inhibits the formation of oral biofilm and reduces the number of subgingival microbes. The photodynamic therapy (PDT) leads to formation of highly reactive nacent oxygen which causes bacterial cell death. This case report compares the treatment outcome of AgP with antimicrobial photodynamic therapy and ozonized water. The right side of a AgP diagnosed patient was treated by scaling and root planing (SRP) followed by subgingival irrigation with ozone water, while the left side was treated with SRP followed by PDT. After four sessions of irrigation, higher pocket reduction, more clinical attachment gain, and lower bacterial load were found in the segment treated with PDT.
