Objectives Periodontitis is an inflammatory disease caused by bacteria present in the dental plaque. However, the role of two oral protozoans, Entamoeba gingivalis and Trichomonas tenax, in patients with the periodontal disease remains largely unknown in Taiwan. Therefore, we investigated the prevalence of oral microbial infections between the sites with mild gingivitis and chronic periodontitis in patients with periodontitis. Materials and Methods We collected 60 dental plaque samples from sites with mild gingivitis (probing depth E. gingivalis and T. tenax were detected in 44 (74.07%) and 14 (23.33%) of all samples, respectively. Among oral bacteria, P. gingivalis, T. denticola, and T. forsythia were detected in 50 (83.33%), 47 (78.33%), and 48 (80.0%) samples, respectively. Furthermore, the infection rates of T. tenax and T. forsythia were significantly different between the sites with mild gingivitis and chronic periodontitis. Conclusions This study, which is the first to analyze E. gingivalis and T. tenax presence among patients with periodontitis in Taiwan, revealed an association between periodontitis and oral microbes. Clinical Relevance: Compared with the different sites with mild gingivitis and chronic periodontitis, chronic is more likely to also have the infection rates of T. tenax and T. forsythia. These oral protozoans and bacteria may be the reason for chronic periodontitis in Taiwan. |
