Abstract
BACKGROUND The use of systemic azithromycin (AZT) and amoxicillin/metronidazole (AMX/MTZ) as adjuncts provided additional clinical and microbiological benefits over subgingival instrumentation alone. However, the superiority of one antibiotic regimen over another has not been proven. Therefore, the aim of this systematic review and meta-analyses was to evaluate the clinical efficacy and safety of subgingival instrumentation (SI) in conjunction with the systemic use of AZT or AMX/MTZ for the treatment of periodontitis from current published literature. METHODS Electronic databases were searched to identify randomized controlled trials (RCTs), controlled clinical trials, prospective and retrospective human studies that compared the adjunctive use of systemic AZT to AMX/MTZ with SI in the treatment of periodontitis. The eligibility criteria were defined based on the participant (who had periodontitis), intervention (SI with adjunctive use of systemic AZT), comparison (SI with adjunctive use of systemic AMX/MTZ), outcomes (primary outcome: changes in probing pocket). The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool. Data were analysed using a statistical software program. RESULTS Five studies with 151 participants with periodontitis were included in the present review. Of these, 74 participants received adjunctive AZT, while the remaining participants received AMX/MTZ as an adjunct to SI. The adjunctive use of AZT and AMX/MTZ had comparable changes in probing pocket depths at 1-3 months with no statistically significant difference (mean difference (MD) 0.01; 95% CI -0.20 to 0.22; P = 0.94). The adjunctive use of AZT had significantly fewer number of residual sites with probing pocket depths of ≥5 mm at 1-3 months compared to the adjunctive use of AMX/MTZ (MD -3.41; 95% CI -4.73 to -2.10; P < 0.0001). The prevalence rates of adverse events among participants who received AZT and AMX/MTZ were 9.80% and 14.8%, respectively. The meta-analysis showed that the difference between the two groups was not statistically significant (risk ratio 0.69; 95% CI 0.28 to 1.72; P = 0.43). CONCLUSIONS Within the limitation of this review, there was no superiority between AZT and AMX/MTZ in terms of mean changes in probing pocket depths, clinical attachment level, bleeding on probing at 1-3 months. AZT seem to be associated with less sites with residual probing pocket depths of ≥5 mm at 1-3 months and fewer adverse events compared with AMX/MTZ. © 2023 Australian Dental Association.

Synthesis, Characterization, Cytotoxicity Analysis and Evaluation of Novel Heterocyclic Derivatives of Benzamidine against Periodontal Disease Triggering Bacteria. Antibiotics (Basel) 2023; 12:antibiotics12020306. [PMID: 36830219 PMCID: PMC9952644 DOI: 10.3390/antibiotics12020306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 01/30/2023] [Accepted: 01/31/2023] [Indexed: 02/05/2023] Open
Abstract
Periodontal disease (PD) is multifactorial oral disease that damages tooth-supporting tissue. PD treatment includes proper oral hygiene, deep cleaning, antibiotics therapy, and surgery. Despite the availability of basic treatments, some of these are rendered undesirable in PD treatment due to side effects and expense. Therefore, the aim of the present study is to develop novel molecules to combat the PD triggering pathogens. The study involved the synthesis of 4-((5-(substituted-phenyl)-1,3,4-oxadiazol-2-yl)methoxy)benzamidine (5a-e), by condensation of 2-(4-carbamimidoylphenoxy)acetohydrazide (3) with different aromatic acids; and synthesis of 4-((4-(substituted benzylideneamino)-4H-1,2,4-triazol-3-yl)methoxy)benzamidine (6a-b) by treatment of compound 3 with CS2 followed by hydrazination and a Schiff reaction with different aromatic aldehydes. Synthesized compounds were characterized based on the NMR, FTIR, and mass spectrometric data. To assess the effectiveness of the newly synthesized compound in PD, new compounds were subjected to antimicrobial evaluation against P. gingivalis and E. coli using the micro-broth dilution method. Synthesized compounds were also subjected to cytotoxicity evaluation against HEK-293 cells using an MTT assay. The present study revealed the successful synthesis of heterocyclic derivatives of benzamidine with significant inhibitory potential against P. gingivalis and E. coli. Synthesized compounds exhibited minimal to the absence of cytotoxicity. Significant antimicrobial potential and least/no cytotoxicity of new heterocyclic analogs of benzamidine against PD-triggering bacteria supports their potential application in PD treatment.

Abstract
This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis-centered interpretation. Reference is made to anerobic microbiology and to the discovery of select periodontal pathogens and their virulence factors, as well as to biofilms. The evolution of contemporary molecular methods and high-throughput platforms is highlighted in appreciating the breadth and depth of the periodontal microbiome. Finally clinical microbiology is brought into perspective with the contribution of different microbial species in periodontal diagnosis, the combination of microbial and host biomarkers for this purpose, and the use of antimicrobials in the treatment of the disease.

Systemic azithromycin as an adjunct to scaling and root planing in patients with stage III/IV periodontitis: 12-month results of a randomized controlled clinical trial. Clin Oral Investig 2021; 25:5997-6006. [PMID: 33786649 DOI: 10.1007/s00784-021-03906-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 03/23/2021] [Indexed: 01/28/2023]
Abstract
OBJECTIVES To determine whether azithromycin (AZI) as an adjunct to scaling and root planing (SRP), when compared to placebo, decreases the number of sites demonstrating pocket depth (PD) ≥ 5 mm and bleeding on probing (BOP) 12 months post-treatment in stage III/IV periodontitis patients. MATERIALS AND METHODS In a double-blind randomized parallel-arm placebo-controlled trial, 40 stage III/IV periodontitis patients received steps 1 and 2 of periodontal treatment in two sessions within 7 days. Patients then received systemic antibiotic therapy (n = 20; AZI 500 mg/day, 3 days) or placebo (n = 20). Additional instrumentation of residual diseased sites (DS) - sites with PD ≥ 5 mm and BOP - was performed at the 3-, 6- and 9-month follow-ups. The primary outcome variable was the number of DS at the 12-month re-evaluation. Using a multivariate multilevel logistic regression model, the effects of gender, age, antibiotic therapy, presence of Porphyromonas gingivalis or Aggregatibacter actinomycetemcomitans, smoking, tooth being a molar and interdental location were evaluated. RESULTS The number of DS after 12 months was similar in the test (median (Me) = 4, interquartile range (IQR) = 0-6) and control (Me = 3, IQR = 1-6.5) groups. Both groups showed substantial but equivalent improvements in periodontal parameters, with no intergroup differences at initially shallow or deep sites. The logistic regression showed a lower odds ratio (OR) for the healing of DS on molars (OR = 0.29; p < 0.001) and in smokers (OR = 0.36; p = 0.048). CONCLUSION Stage III/IV periodontitis patients showed significant but comparable improvements in periodontal parameters and the number of residual DS at the 12-month revaluation regardless of treatment type. This may have been the result of the additional instrumentation received by patients at residual DS in both treatment groups. CLINICAL RELEVANCE Treatment with AZI + SRP provided no additional benefits after 12 months in terms of periodontal parameters or the number of persisting sites with PD ≥ 5 mm + BOP as compared to SRP plus placebo.

Antimicrobial photodynamic therapy efficacy against specific pathogenic periodontitis bacterial species. Photodiagnosis Photodyn Ther 2020; 30:101688. [PMID: 32087294 DOI: 10.1016/j.pdpdt.2020.101688] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 01/29/2020] [Accepted: 02/18/2020] [Indexed: 12/20/2022]
Abstract
BACKGROUND To determine the safety and efficacy of antimicrobial photodynamic therapy (aPDT) combination of 0.33 mM Toluidine Blue O (TBO) with 60 mW/cm2 LED irradiation for 5 min that we had established, this study investigated the cytotoxic effect of aPDT combination on mammalian oral cells (gingival fibroblast and periodontal ligament cells) and compared the antimicrobial efficacy of antibiotics (the combination of amoxicillin (AMX) and metronidazole (MTZ)) against representative periodontitis pathogenic bacteria (Porphyromonas gingivalis, Fusobacterium nucleatum, and Aggregatibacter actinomycetemcomitans) versus our aPDT combination. RESULT aPDT combination did not show any detectable effect on the viability of Streptococcus sanguinis or Streptococcus mitis, the most common resident species in the oral flora. However, it significantly reduced CFU values of P. gingivalis, F. nucleatum, and A. actinomycetemcomitans. The cytotoxicity of the present aPDT combination to mammalian oral cells was comparable to that of standard antiseptics used in oral cavity. In antimicrobial efficacy test, the present aPDT combination showed equivalent bactericidal rate compared to the combination of AMX + MTZ, the most widely used antibiotics in the periodontitis treatment. The bactericidal ability of the AMX + MTZ combination was effective against all five bacteria tested regardless of the bacterial species, whereas the bactericidal ability of the aPDT combination was effective only against P. gingivalis, F. nucleatum, and A. actinomycetemcomitans, the representative periodontitis pathogenic bacterial species. CONCLUSION The present study demonstrated the safety and efficacy of the present aPDT combination in periodontitis treatment. TBO-mediated aPDT with LED irradiation has the potential to serve as a safe single or adjunctive antimicrobial procedure for nonsurgical periodontal treatment without damaging adjacent normal oral tissue or resident flora.
