Abstract
Periodontitis is characterized by alveolar bone destruction and is one of the most common chronic oral diseases. Inflammatory cytokines released by pyroptosis, which can be triggered by oxidative stress, are critical in the development of periodontitis. This study aims to clarify whether oxidative stress causes osteoblast dysfunction by inducing pyroptosis in the process of periodontitis. We found that treatment with lipopolysaccharide (LPS) led to NLRP3 inflammasome-mediated pyroptosis of MG63 cells as well as decreased cell migration. Of note, LPS stimulation increased LDH release in a time- and dose-dependent manner. However, inhibition of reactive oxygen species with N-acetyl-L-cysteine attenuated oxidative stress-mediated pyroptosis and improved migration injury in osteoblasts treated with LPS. Further, inhibition of the NLRP3 inflammasome with MCC950 improved osteoblast migration and restored the expression of osteogenic differentiation-related proteins such as COL 1, RUNX 2 and ALP. In conclusion, oxidative stress caused by LPS induces pyroptosis in osteoblasts, leading to osteogenic dysfunction.

Abstract
OBJECTIVE Our previous studies found that a salmon DNA-based scaffold containing protamine promoted bone regeneration of the calvarial defects of rats. The aim of the present pilot study was to examine the influence of the DNA/protamine (DP) complex on bone regeneration of a saddle type, alveolar ridge defects of the dog mandible. DESIGN Alveolar ridge defects were performed in the mandibles of five adult female beagles. The following three treatment modalities were randomly allocated: (1) the DP complex paste, (2) a beta-tricalcium phosphate (β-TCP), and (3) a blank (control). Healing of bone defects were evaluated by periapical radiography, micro-computed tomography (micro-CT), and histology. RESULTS Periodical radiographic images revealed that a higher percentage of regenerated bone height was consistently achieved in the DP group, as compared with blank controls. All three-dimensional, sagittal, and coronal images of micro-CT showed increased amounts of newly formed bone and a greater bone volume/ tissue volume ratio, as compared with the blank and β-TCP groups. In contrast, there was no significant difference in bone mineral density among the groups. Histological analysis confirmed that the alveolar bone defects were filled with newly formed bone with mature and compact properties in the DP group. CONCLUSIONS These findings indicate that the DP complexes enhanced regeneration of vertical alveolar bone defects of the dog mandible.
