Fixed prosthodontic dental restorations can potentially affect the periodontal tissues and vice versa, the periodontium can influence the longevity and esthetic appearance of dental restorations. We proposed an investigation on total bacterial load, specific periodontal pathogens, and periodontal clinical parameters in patients with dental fixed prosthesis and different degrees of periodontal tissue loss that followed photoactivation therapy (PDT) adjunctive to scaling and root planing. The study was conducted on 160 subjects, which were randomly assigned to scaling and root planing (SRP) alone (52 subjects, 256 sites), SRP and chlorhexidine rinsing (58 subjects, 276 sites), and SRP plus PDT (50 subjects, 318 sites). Periodontal parameters (plaque index, bleeding on probing, probing depth, and clinical attachment loss), followed by total bacterial load and specific periodontal pathogens (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola) were examined in each patient at baseline, one and six months after. PDT exerted significant improvements both in clinical and microbiological load after one month, and these results were maintained 6 months after when compared to chlorhexidine rinsing or SRP alone, especially in severe periodontitis cases. Photoactivation therapy as an adjunctive periodontal therapeutic method was efficient in offering supplementary periodontal improvements in the clinical and microbiological parameters of patients with fixed dental prosthesis, particularly in severe periodontitis cases.
Periodontal disease is progressive and episodic in nature, with tissue destruction resulting from the host response to bacterial antigens and irritants.This study aimed to evaluate the genotype of a certain group of pathogen agents. In order to to this we used a total of 45 patients with PAG included in the epidemiological analyzes with a mean age of 34.7 Four samples were collected from the subgingival plaque from each patient, a total of 224 samples of dental plaques were investigated. All samples were tested for the presence of Tannerella forsythensis, Porphyromonas gingivalis and Treponema denticola. We found that patients had a large number of pockets colonized by Tannerella forsythensis gingivalis (88.6%) Porphyromonas gingivalis (59%) and Aggregatibacter actinomycetemcomitans (25%). The data of this study support the evidence Tannerella forsythensis as a periodontopatogen and confirmed a strong association between Porphyromonas gingivalis and Tannerella forsythensis in aggressive periodontitis and support previous findings that generalized aggressive periodontitis are associated with more complex microbiota.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
