  1. 01AnimalAnimal study (in vivo)Efficacy outcome

    In rats with LPS-induced periodontitis, VIP caused a dose-dependent decline in alveolar bone loss compared with LPS alone, but the differences were not significant.

    In plain wordsIn rats with gum disease, VIP lowered bone loss in a dose-linked way, but the difference from rats given only LPS was not significant.

    Summary
    The application of VIP caused a dose-dependent decline in alveolar bone loss compared to the LPS group, but the differences were not significant (P >0.05).
