영어 초록
Periodontal inflammation increases the risk of tooth loss, particularly in cases where there is an associated loss of alveolar bone and periodontal ligament (PDL). Histological and morphometric evaluation of periodontal inflammation is difficult. Especially, the lengths of the periodontal ligament and interdental alveolar bone space have not been quan-tified. A quantitative imaging procedure applicable to an animal model would be an important clinical study. The purpose of this study was to quantify the loss of alveolar bone and perio-dontal ligament by evaluation with micro-computed tomo-graphy (micro-CT). Another purpose was to investigate diffe-rences in infections with systemic E. coli LPS and TNF-α on E. coli lipopolysaccharide (LPS) in loss of alveolar bone and periodontal ligament model on mice. This study showed that linear measurements of alveolar bone loss were repre-sented with an increasing trend of the periodontal ligament length and interdental alveolar process space. The effects of systemic E. coli LPS and TNF-α on an E. coli LPS-induced periodontitis mice model were investigated in this research. Loss of periodontal ligament and alveolar bone were eval-uated by micro-computed tomography (micro-CT) and cal-culated by the two- and three dimensional microstructure morphometric parameters. Also, there was a significantly increasing trend of the interdental alveolar process space in E. coli LPS and TNF-α on E. coli LPS compared to PBS. And E. coli LPS and TNF-α on E. coli LPS had a slightly increa-sing trend of the periodontal ligament length. The increa-sing trend of TNF-α on the LPS-induced mice model in this experiment supports the previous studies on the contribu-tion of periodontal diseases in the pathogenesis of systemic diseases. Also, our findings offer a unique model for the study of the role of LPS-induced TNF-α in systemic and chronic local inflammatory processes and inflammatory diseases. In this study, we performed rapidly quantification of the perio-dontal inflammatory processes and periodontal bone loss using micro-computed tomography (micro-CT) in mice.참고 자료
