Alternative treatment methods for pathogens and microbial biofilms are required due to the widespread rise in antibiotic resistance. Antimicrobial photodynamic therapy (aPDT) has recently gained attention as a novel method to eradicate pathogens. The aim of this study was to evaluate the antimicrobial effects of a novel aPDT method using visible light (vis) and water infiltrated infrared A (wIR...
UNLABELLED Investigate the presence of Lactobacillus reuteri in saliva after supplementation with L. reuteri and the probiotic effect of L. reuteri on plaque index and supra- and subgingival microbiota. MATERIAL AND METHODS The study included 23 healthy individuals, randomised into test or control subjects. At baseline and after 12 weeks saliva samples, plaque index and supra- and subgingival...
Eikenella corrodens is a commensal subgingival bacterium commonly found in both periodontally nondiseased and diseased subjects. The present study examined the clonal diversity and stability of subgingival E. corrodens over time. Ninety-five subjects were enrolled at the baseline examination, including 44 periodontally nondiseased subjects and 51 subjects with aggressive periodontitis. Twenty-t...
The predominant dental plaque flora of 15 female beagle dogs (1,3 and 6 year old) with naturally developed gingivitis was studied using a continuous anaerobic culturing technique. Supraand sul^ingival plaque samples from the buccal aspect of the upper third premolar were cultured on various growth media and the organisms were partially characterized. The flora in all dogs was composed mostly of...
This study evaluates the antimicrobial susceptibility and composition of subgingival biofilms in generalized aggressive periodontitis (GAP) patients treated using mechanical/antimicrobial therapies, including chlorhexidine (CHX), amoxicillin (AMX) and metronidazole (MET). GAP patients allocated to the placebo (C, n = 15) or test group (T, n = 16) received full-mouth disinfection with CHX, scali...
Porphyromonas gingivalis is a major pathogen in destructive periodontal disease in humans. Detection and quantification of this microorganism are relevant for diagnosis and treatment planning. The prevalence and quantity of P. gingivalis in subgingival plaque samples of periodontitis patients were determined by anaerobic culture and real-time PCR amplification of the 16S small-subunit rRNA gene...
This study investigated the effect of non-surgical periodontal therapy on the composition of subgingival microbiota of patients with chronic kidney disease (CKD). Sixteen CKD pre-dialysis individuals (CKD) and 14 individuals without clinical evidence of kidney disease (C) presenting chronic periodontitis were treated by scaling and root planing. Subgingival samples were collected from each pati...
Periodontal pocketing, attachment loss, bone loss, and subgingival inflammation are among the clinical signs of periodontitis. Periodontal pockets and subgingival inflammation give evidence of actual periodontal infection, whereas attachment loss and bone loss are symptoms of former periodontitis that has caused tissue destruction in the past. Several clinical or radiographic methods are used t...
BACKGROUND The diagnosis of the progression of periodontitis presently depends on the use of clinical symptoms (such as attachment loss) and radiographic imaging. The aim of the multicenter study described here was to evaluate the diagnostic use of the bacterial content of subgingival plaque recovered from the deepest pockets in assessing disease progression in chronic periodontitis patients. ...
AIM The objective was to determine clinical and microbiological effects and perceived treatment discomfort of root debridement by subgingival air polishing compared with ultrasonic instrumentation during supportive periodontal therapy (SPT). MATERIAL AND METHODS The trial was conducted as a split-mouth designed study of 2-month duration including 20 recall patients previously treated for chro...
