Microbiological and clinical effects of probiotics and antibiotics on nonsurgical treatment of chronic periodontitis: a randomized placebo- controlled trial with 9-month follow-up.
    Journal of applied oral science : revista FOB, 2018, Jan-18, Volume: 26

    The aim of this double-blind, placebo-controlled and parallel- arm randomized clinical trial was to evaluate the effects of Lactobacillus rhamnosus SP1-containing probiotic sachet and azithromycin tablets as an adjunct to nonsurgical therapy in clinical parameters and in presence and levels of Tannerella forsythia, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. Forty-seven systemically healthy volunteers with chronic periodontitis were recruited and monitored clinically and microbiologically at baseline for 3, 6 and 9 months after therapy. Subgingival plaque samples were collected from four periodontal sites with clinical attachment level ≥1 mm, probing pocket depth ≥4 mm and bleeding on probing, one site in each quadrant. Samples were cultivated and processed using the PCR technique. Patients received nonsurgical therapy including scaling and root planing (SRP) and were randomly assigned to a probiotic (n=16), antibiotic (n = 16) or placebo (n = 15) group. L. rhamnosus SP1 was taken once a day for 3 months. Azithromycin 500mg was taken once a day for 5 days. All groups showed improvements in clinical and microbiological parameters at all time points evaluated. Probiotic and antibiotic groups showed greater reductions in cultivable microbiota compared with baseline. The placebo group showed greater reduction in number of subjects with P. gingivalis compared with baseline. However, there were no significant differences between groups. The adjunctive use of L. rhamnosus SP1 sachets and azithromycin during initial therapy resulted in similar clinical and microbiological improvements compared with the placebo group.

Predictors of clinical outcomes after periodontal treatment of aggressive periodontitis: 12-month randomized trial.
    Brazilian oral research, 2016, May-20, Volume: 30, Issue:1

    Little is known about the factors that may be used in clinical practice to predict the therapeutic response of aggressive periodontitis patients. The aim of this study was to determine predictors of clinical outcomes after non-surgical treatment of aggressive periodontitis. A total of 24 patients (aged 13-26 years) received oral hygiene instructions, as well as subgingival scaling and root planing. Twelve subjects received systemic azithromycin at random. Clinical variables were assessed at baseline, 3, 6, 9, and 12 months. Baseline microbiological assessment was performed by checkerboard DNA-DNA hybridization. Multivariable models used generalized estimating equations. There were significant improvements in the entire sample in regard to pocket depth, clinical attachment level and bleeding on probing. Significant predictors of a reduction in mean pocket depth were: use of azithromycin, non-molar teeth, generalized disease and baseline pocket depth. Absence of plaque predicted a 0.22 mm higher attachment gain, whereas a baseline pocket depth ≥7 mm predicted a 1.36 mm higher attachment loss. Azithromycin, plaque, and baseline pocket depth were significant predictors of bleeding on probing. The concomitant presence of all three red complex species predicted a 0.78 mm higher attachment loss. It may be concluded that dental plaque, tooth type, disease extent, baseline pocket depth, and use of azithromycin were significant predictors of the clinical response to treatment for aggressive periodontitis in young individuals. Moreover, the presence of multiple periodontal pathogens may predict challenges in achieving a favorable outcome for aggressive periodontitis.

Effect of gingivitis on azithromycin concentrations in gingival crevicular fluid.
    Journal of periodontology, 2012, Volume: 83, Issue:9

    Macrolide antibiotics yield high concentrations in inflamed tissue, suggesting that their levels in gingival crevicular fluid (GCF) could be increased at gingivitis sites. However, the increased volume of GCF associated with gingivitis could potentially dilute macrolides. To determine whether these assumptions are correct, the bioavailability of systemically administered azithromycin was compared in GCF from healthy and gingivitis sites.. Experimental gingivitis was induced in one maxillary posterior sextant in nine healthy individuals. Contralateral healthy sextants served as controls. Participants ingested 500 mg azithromycin, followed by a 250-mg dose 24 hours later. Four hours after the second dose, plaque was removed from experimental sites. GCF was collected from eight surfaces in both the experimental and control sextants and pooled separately. GCF samples were subsequently collected on days 2, 3, 8, and 15, and azithromycin content was determined by agar diffusion bioassay.. On days 2 and 3, the pooled GCF volume at experimental sites was significantly higher than at control sites (P <0.01), and the total azithromycin mass in 30-second GCF samples pooled from experimental sites was significantly higher than at control sites (P <0.02). However, there were no significant differences in azithromycin concentration between the experimental and control pools at any point. Concentrations exceeded 7.3 μg/mL on day 2 and 2.5 μg/mL on day 15.. Azithromycin concentrations are similar in GCF from gingivitis sites and healthy sites, suggesting that the processes that regulate GCF azithromycin concentration can compensate for local inflammatory changes.

Azithromycin as an adjunctive treatment of generalized severe chronic periodontitis: clinical, microbiologic, and biochemical parameters.
    Journal of periodontology, 2012, Volume: 83, Issue:12

    This study examines the efficacy of azithromycin in combination with non-surgical periodontal therapy on clinical and microbiologic parameters and gingival crevicular fluid (GCF) matrix metalloproteinases-8 (MMP-8) levels over 6 months in patients with severe generalized chronic periodontitis (CP).. Twenty-eight of 36 patients with severe generalized CP were included in this randomized, double-masked, placebo-controlled, parallel-arm study. They were randomly assigned to azithromycin or placebo groups (500 mg, once daily for 3 days). Probing depth (PD), clinical attachment level, dichotomous presence or absence of supragingival plaque accumulation, and bleeding on probing were recorded. GCF samples were obtained from one single-rooted tooth with PD ≥ 6 mm, whereas microbiologic samples were collected from two single-rooted teeth with PD ≥ 6 mm. Microbiologic parameters were analyzed by quantitative real-time polymerase chain reaction for Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Fusobacterium nucleatum, Prevotella intermedia, and total bacteria. GCF MMP-8 levels were determined by immunofluorescence assay.. Azithromycin and placebo groups demonstrated similar but significant improvements in all clinical parameters (P <0.05). A. actinomycetemcomitans, P. gingivalis, T. forsythia, P. intermedia, and total bacteria significantly decreased over the 6-month period in both groups, whereas F. nucleatum was significantly reduced in all visits in the azithromycin group, with the levels also being lower compared with those of the placebo group (P <0.05). The azithromycin and placebo groups exhibited significant reduction in GCF MMP-8 levels at the post-treatment visit and at 2 weeks (P <0.05).. On the basis of the present findings, it can be concluded that adjunctive azithromycin provides no additional benefit over non-surgical periodontal treatment on parameters investigated in patients with severe generalized CP.

Adjunctive azithromycin in the treatment of aggressive periodontitis: microbiological findings of a 12-month randomized clinical trial.
    Journal of dentistry, 2012, Volume: 40, Issue:7

    To compare the subgingival microbiological outcomes of azithromycin or placebo as adjuncts to scaling and root planing (SRP) in the treatment of aggressive periodontitis (AgP), and to secondarily evaluate the microbiological effect of supragingival scaling in AgP patients.. Twenty-four AgP subjects 13-26 years of age received a 15-day programme of supragingival scaling (SC) and were then randomly assigned to SRP with systemic azithromycin or placebo. Subgingival samples were taken with sterile paper points at baseline, 15 days after SC, and at 3, 6 and 12 months following SRP. Microbiological analysis was performed by the checkerboard DNA-DNA hybridization.. Changes in bacterial levels from baseline to 15 days after SC were similar in the 2 groups. When subjects were analysed as a single group, significant reductions after SC were observed for Actinomyces gerencseriae, Capnocytophaga ochracea, and Treponema denticola. During the 12-month follow-up, levels of most of the bacteria decreased in both groups in a similar pattern. For instance, Actinomyces israelli, Veillonella parvula, Streptococcus gordonii, C. ochracea, Eikenella corrodens, Eubacterium nodatum, Fusobacterium periodonticum and Fusobacterium nucleatum ssp. polymorphum decreased significantly within the groups.. Azithromycin was ineffective in lowering the subgingival levels of important putative periodontal pathogens in young AgP subjects compared to placebo.. Scaling and root planing with adjunctive systemic azithromycin provides little additional benefit compared to placebo in reductions of major subgingival periodontal pathogens.

J Periodont Res 2012; 47: 729-739. © 2012 John Wiley & Sons A/S Background and Objective:  To study the effectiveness of azithromycin in combination with nonsurgical periodontal therapy on clinical and microbiological parameters, and on the MMP-8 and TIMP-1 levels in gingival crevicular fluid, over a 6-mo time-period in patients with generalized aggressive periodontitis..   Thirty-two patients with generalized aggressive periodontitis were included in this randomized, double-blind, placebo-controlled, parallel-arm study. They were randomly assigned to azithromycin or placebo groups (500 mg once daily for 3 d). Probing depth, clinical attachment levels, presence of bleeding on probing and plaque were recorded. Gingival crevicular fluid samples were obtained from one single-rooted tooth, while microbiological samples were obtained from two single-rooted teeth, all with a probing depth of ≥ 6 mm. Microbiological parameters were analyzed by quantitative real-time PCR for Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Fusobacterium nucleatum, Prevotella intermedia and total bacteria. Gingival crevicular fluid biomarkers were determined by immunofluorometric assay and ELISA..   All clinical parameters improved, and microbiological parameters and gingival crevicular fluid MMP-8 levels significantly decreased, over the 6-mo period (p < 0.05); both groups demonstrated similar improvements. The azithromycin group presented a higher percentage of deep pockets resolved (probing depth reduction of ≥ 3 mm from baseline) compared with the placebo group at 1 mo (p < 0.05)..   Adjunctive azithromycin therapy provides no additional benefit over nonsurgical periodontal treatment on clinical parameters, microbiological parameters and gingival crevicular fluid biochemical markers investigated in patients with generalized aggressive periodontitis.

Effects of irrigation with an antiseptic and oral administration of azithromycin on bacteremia caused by scaling and root planing.
    Journal of periodontology, 2010, Volume: 81, Issue:11

    Transient bacteremia frequently occur secondary to several periodontal procedures. The purpose of the present study is to investigate the effects of irrigation with an essential oil-containing antiseptic (EO) and oral administration of azithromycin (AZM) on bacteremia caused by scaling and root planing (SRP).. Thirty patients with chronic periodontitis were randomly assigned to three groups (control, EO, and AZM). The EO group received quadrant subgingival irrigation with EO, and mouthrinsing was continued at home for 1 week. Oral administration of AZM was started 3 days before SRP in the AZM group. No adjunctive treatment was performed before SRP in the control group. Peripheral blood and subgingival plaque were collected at baseline and after 1 week. The second blood sample was taken 6 minutes after the initiation of quadrant SRP. The blood samples were cultured and analyzed for bacteremia. Quantitative analysis of periodontopathic bacteria in the sulcus was performed using the polymerase chain reaction Invader method.. Bacteremia incidence rates were 90%, 70%, and 20% for the control, EO, and AZM groups, respectively. Significant reduction of the incidence of bacteremia was shown in the AZM group only (P <0.01). Subgingival bacterial counts significantly decreased in both the EO and AZM groups (P <0.01).. Quadrant SRP frequently induced bacteremia. Although AZM was effective in reducing bacteremia incidence, EO showed less effectiveness.

Azithromycin as an adjunctive treatment of aggressive periodontitis: 12-months randomized clinical trial.
    Journal of clinical periodontology, 2008, Volume: 35, Issue:8

    To assess the effect of systemic azithromycin as a supplement to scaling and root planing (SRP) in the treatment of aggressive periodontitis (AgP).. Twenty-four individuals (13-26 years old) underwent a plaque control program, and then were treated with SRP. Subjects were assigned randomly into two groups; the test group used 500 mg azithromycin once a day for 3 days, whereas the control group used a placebo. Clinical variables were assessed at baseline, 3, 6, 9, and 12 months. The periodontal status at baseline and 12 months was compared using the Wald test, and adjusting for the effect of clustering of teeth within subjects.. There were no significant differences in visible plaque, gingival bleeding, and supragingival calculus between groups throughout the study. Periodontal probing depth (PPD) and clinical attachment level improved significantly from baseline to 12 months in both groups, with the test group showing significantly more reduction in mean PPD compared with controls (2.88 mm versus 1.85 mm, respectively, p=0.025). Subjects administering azithromycin showed a higher percentage of teeth with attachment gain >or=1 mm (81.34 versus 63.63, p=0.037), whereas the controls had higher percentage of teeth with attachment loss >or=1 mm (11.57 versus 2.24, p=0.015).. The adjunctive use of azithromycin has the potential to improve periodontal health of young patients with AgP.

Microbiological changes associated with four different periodontal therapies for the treatment of chronic periodontitis.
    Oral microbiology and immunology, 2008, Volume: 23, Issue:2

    To examine subgingival microbiological changes in chronic periodontitis subjects receiving scaling and root planing (SRP) alone or with systemically administered azithromycin, metronidazole or a sub-antimicrobial dose of doxycycline.. Ninety-two periodontitis subjects were randomly assigned to receive SRP alone or combined with azithromycin, metronidazole or sub-antimicrobial dose doxycycline. Subgingival plaque samples taken at baseline, 2 weeks, and 3, 6, and 12 months were analyzed for 40 bacterial species using checkerboard DNA-DNA hybridization. Percentage of resistant species and percentage of sites harboring species resistant to the test antibiotics were determined at each time-point.. All treatments reduced counts of red complex species at 12 months, although no significant differences were detected among treatment groups for most species at all time-points. Both antibiotics significantly reduced counts of red complex species by 2 weeks. Percentage of resistant isolates increased in plaque samples in all adjunctive treatment groups, peaking at the end of administration, but returned to pretreatment levels by 12 months.. The significant reduction of red and orange complex species at 2 weeks in the subjects receiving SRP plus azithromycin or metronidazole may have contributed to a better clinical response in these treatment groups. Therapy did not appear to create lasting changes in the percentage of resistant isolates or sites harboring resistant species.

Antibiotic resistance testing of the total implant-associated micro-flora and its pure isolates.
    European journal of medical research, 2007, Mar-26, Volume: 12, Issue:3

    The aim of the present study was to examine antibiotic resistant strains among the implant-associated microorganisms in vitro, first as mixed cultures and again as pure isolates for resistance to one of five antibiotics.. Samples were taken with sterile paper points from the deepest pocket of one implant per patient (n = 24) to culture the total oral micro-flora. The samples were streaked on agar (Schaedler or BHI) and incubated for 7 d in an anaerobic atmosphere. All colonies were rinsed off the plates, aliquots were added to top-agar. Susceptibility against antibiotics (ampicillin, ampicillin + sulbactam, azithromycin and penicillin, moxifloxacin) was determined using the Etest. Resistant strains were picked, purified and characterized, and the Etests were repeated with a selection of the pure isolates.. The majority of the mixed cultures (67 - 100 %) showed complete antibiotic resistance. No association with clinical parameters like pocket depth, bleeding on probing or insertion of implants into transplanted bone could be found. Smoking and the surface of the implant also had no influence. 23 % of the 597 resistant colonies contained only yeasts, mostly isolated from irradiated tumour patients. Of the 458 resistant bacteria, the majority were Gram-positive cocci or rods. Staphylococci and M. micros were detected occasionally. The resistance for the 138 selected pure isolates was in most cases lower than for the total micro-flora, irrespective of the antibiotic.. The higher resistance of the total flora might be explained by synergistic interactions between its members.
