An 80 year old female was admitted with an eight week history of fever associated with painful swelling of her right thigh, and a long history of poor dentition. Culture of blood stained fluid aspirated from the abscess grew Aggregatibacter actinomycetemcomitans (Aa) sensitive to ampicillin and cephalosporins. Transoesophageal echocardiography indicated endocarditis. Four weeks treatment with intravenous ceftriaxone and appropriate dental care was followed by full recovery.

Objective: To provide a comprehensive summary of the available evidence on the oral microbiota of humans and non-human primates about the etiology of periodontal disease.
Design: An integrative literature review was conducted on 398 clinical and observational articles published between 2010 and 2024 using searches in the MEDLINE/PubMed, Virtual Health Library, and SciELO databases. After the screening, eligibility, data extraction, and methodological quality assessment, 21 studies were selected.

Peri-implantitis associated with dental implants shares characteristics with destructive periodontal diseases. Both conditions are multifactorial and strongly correlated with the presence of microorganisms surrounding the prostheses or natural dentition. This study aimed to evaluate the antimicrobial activity and toxicity of a mucoadhesive hydrogel functionalized with aminochalcone (HAM-15) against Aggregatibacter actinomycetemcomitans, Fusobacterium periodonticum, Prevotella intermedia, Porphyromonas gingivalis, Tannerella forsythia, and Candida albicans.

The objective was to evaluate using unstimulated saliva in detecting and to compare the saliva and subgingival and mucosa membrane occurrence of this periodontal pathogen in patients diagnosed with advanced periodontitis. Patients with advanced forms of periodontitis ( = 220; mean age: 54.03 ± 03 years) at stage III/IV were sampled.

Background: The vehicle in a local drug delivery (LDD) system plays a vital role in delivering the active drug component at the diseased site. Liquid/injectable platelet-rich fibrin (i-PRF), an autologous fibrin matrix, might be used as a vehicle to enmesh drugs and deliver locally at the periodontally diseased sites. This study evaluated the efficacy of the drug (ciprofloxacin [Cip])-loaded i-PRF as a LDD system adjunct to subgingival debridement in subjects with periodontal pockets.

Aims: Bacterial resistance and systemic risks associated with periodontitis underscore the need for novel antimicrobial agents. Cannabis sativa is a promising source of antimicrobial molecules, and cannabidiol (CBD) attracts significant interest. This study evaluated the antibacterial and antibiofilm activity of CBD against periodontopathogens, and assessed its toxicity in vivo model.
