“…Periodontitis is an infectious disease caused by plaque biofilm that leads to the destruction of toothsupporting tissues, with clinical symptoms including attachment loss, periodontal pocket formation, and alveolar bone resorption, which, if left untreated, can gradually lead to tooth loosening or even tooth loss (Petersen and Ogawa, 2012;Kinane et al, 2017;Van der Velden, 2017). There is a growing body of research showing that the health of oral tissues interacts with systemic health (Taylor et al, 2000;Genco and Sanz, 2020;Kapila, 2021;Larvin et al, 2022;Teles et al, 2022). Notably, periodontitis is closely associated with several systemic diseases, including atherosclerotic cardiovascular disease (Beck et al, 2001;Van Dyke et al, 2021;Isola et al, 2022), diabetes (Chapple et al, 2013;Genco and Borgnakke, 2020;Nibali et al, 2022), adverse pregnancy outcomes such as miscarriage and preterm delivery (Canakci et al, 2004;Sanz et al, 2013;Miranda-Rius et al, 2021), rheumatoid arthritis (Bartold and Lopez-Oliva, 2020;Möller et al, 2020;Gonzaĺez-Febles and Sanz, 2021), Alzheimer's disease (Pizza, 2019;Kamer et al, 2020;Torrealba-Garcıá et al, 2021) and inflammatory bowel disease (Cai et al, 2021;Imai et al, 2021;Zhang et al, 2021a;Baima et al, 2022).…”
