Abstract
Although the presence of prosthetic restorations has been associated with plaque accumulation, gingivitis, and periodontitis, there is a lack of large epidemiological investigations providing evidence on the association of prosthetic crowns with periodontitis. This study aimed to analyze the association between the number of prosthetic crowns and the presence of periodontitis. This study was based on the Seventh Korea National Health and Nutrition Examination Survey (2016–2018). A total of 12,689 participants over the age of 19 years were surveyed. Multivariate logistic regression analyses were used to identify the association between the number of prosthetic crowns and periodontitis after adjusting for potential confounders, including demographic variables, socio-economic characteristics, oral health-related variables, and oral and systemic clinical variables. The odds ratio of periodontitis showed statistically significant differences in the anterior and posterior regions, and the prevalence of periodontal disease increased as the number of crown prostheses increased. Participants with 6–10 and 11 prosthetic crowns had 1.24 and 1.28 times higher prevalence of periodontitis, respectively, than patients with no prosthetic crown. The results of this study show that the number of prosthetic crowns present in adults is related to the prevalence of periodontitis.
Highlights
Periodontitis refers to host-mediated inflammation associated with a bacterial biofilm that causes the loss of periodontal attachment [1]
The initiation and progression of periodontitis are dependent on the ecological changes caused by the dysbiosis of microorganisms that develops as anti-bacterial mechanisms generating inflammation and tissue destruction in the gingival sulcus [2]
The presence of prostheses restored on the teeth, along with the anatomy, position, and the relationships of the teeth with each other is associated with plaque accumulation and subsequent gingivitis and periodontitis [3]
Summary
Periodontitis refers to host-mediated inflammation associated with a bacterial biofilm that causes the loss of periodontal attachment [1]. The initiation and progression of periodontitis are dependent on the ecological changes caused by the dysbiosis of microorganisms that develops as anti-bacterial mechanisms generating inflammation and tissue destruction in the gingival sulcus [2]. There is crestal bone resorption along with loss of attachment caused by inflammatory mediators, and the depth of the periodontal pocket increases. The presence of prostheses restored on the teeth, along with the anatomy, position, and the relationships of the teeth with each other is associated with plaque accumulation and subsequent gingivitis and periodontitis [3]. The process of fabrication and delivery of tooth-supported prostheses has the potential to affect periodontal tissues by causing trauma or due to allergic reactions to dental materials [4]. It has been reported that the deeper the placement of the subgingival crown margin in the gingival sulcus, the more
