The effect of supragingival biofilm re-development on the subgingival microbiota in chronic periodontitis

Abstract

Biofilm re-development was very similar between CP and PH individuals, although microbial re-growth occurred few hours earlier in PH than PC. Only 3 species in the subgingival biofilm differed in re-colonization between groups. Thus, we reject the hypothesis that re-colonization of biofilm in CP patients is more intense and faster than in individuals with PH.

Efficacy of Non-Surgical Periodontal Therapy with Adjunctive Methylene Blue and Toluidine Blue O Mediated Photodynamic in Treatment of Periodontitis: A Randomized Clinical Trial

“…However, favorable outcomes of this treatment are not always ensured, and diverse responses could be observed between patients and even periodontal sites within the same patient. Different treatments were introduced as adjunct to RSD, such as antimicrobial therapy [ 5 , 7 , 9 ]. However, possible emergence of side effects and bacterial resistance in association with antibiotics highlighted PDT as a revolutionary solution for these issues [ 11 , 12 ].…”

“…Periodontal treatment basically aims to eradicate supra- and subgingival biofilm masses, minimizing the pathogenic bacteria load responsible for the progression of PD [ 5 ]. Non-surgical periodontal treatment, root surface debridement (RSD), is used to remove dental biofilm and eradicate pathogenic organisms, with various degrees of clinical success [ 6 ].…”

Colonization dynamics of subgingival microbiota in recently installed dental implants compared to healthy teeth in the same individual: a 6-month prospective observational study

“…Sample size was calculated based on two standard deviations (5.27 and 5.41 counts x10 6 ) of the mean counts of a bacterial species in samples from the same healthy individuals at two different timepoints. 24 Detection of a difference required a minimum of 13 individuals with approximately 95% CI for the difference between means (D) D - 4.240 to D + 4.240. Sample size calculation was performed using a free software (WinPep, http://www.brixtonhealth.com/pepi4windows.html).…”
