Abstract

Objectives: The aim of this article was to perform a systematic review on the effectiveness of local adjuvant therapies in the treatment of aggressive periodontitis (AgP), now reported as periodontitis grade C.

Materials and methods: The authors selected randomized clinical trials of AgP patients who received local therapy as adjuvants to non-surgical periodontal with a duration of at least 90 days. Seven databases were searched up to January 2020. The gain in clinical attachment level (CAL) and reduction of probing depth (PD) were the outcomes of interest.

Results: Of the 3583 studies found, only five articles were included in the qualitative analysis. Among the substances analyzed, only 1.2 mg of simvastatin gel (SMV) (1.2 mg/0.1 ml), 1% of alendronate gel (ALN) (10 mg/ml), and 25% metronidazole gel (MTZ) (Elyzol@) showed a significant decrease in the probing depth when compared with their respective control groups. The gain CAL was shown using 1.2 mg SMV gel (1.2 mg/0.1 ml) and 1% ALN gel (10 mg/ml).

Conclusion: Although 1.2 mg SMV gel (1.2 mg/0.1 ml), 1% ALN gel (10 mg/ml), and 25% MTZ gel (Elyzol) have shown better results, local therapies adjuvant to SRP the data found were limited. Future clinical studies with appreciable methodological quality should be conducted.

Clinical relevance: Despite some benefits of local delivery therapy, up to now, it has not been possible to prove the efficacy of local therapy as an adjunct to standard treatment of AgP (periodontitis grade C).
