What are the most common Gram-negative cocci causing oral complications?

Neisseria, Moraxella, Acinetobacter, Veillonella spp.

What are the characteristics of Neisseria species?

Gram-negative cocci occurring in pairs (diplococci), facultative anaerobes, possess a capsule and pili.

What oral and dental problems are associated with Neisseria species?

Biofilm formation, periodontal disease, oral infections such as stomatitis, and septic arthritis.

What are the characteristics of Moraxella species?

Gram-negative cocci occurring in pairs or tetrads, aerobic, known for causing respiratory infections.

What oral and dental complications are associated with Moraxella species?

Dental plaque, dental caries, periodontal disease, dental abscess, gingivitis, and sinusitis-related dental pain.

What are the characteristics of Acinetobacter species?

Gram-negative cocci or coccobacilli, aerobic, ubiquitous in the environment, and can survive in a wide range of conditions.

What oral and dental problems are associated with Acinetobacter species?

Biofilm formation, periodontal disease, and implant-associated infections.

What are the characteristics of Veillonella spp.?

Anaerobic Gram-negative cocci, important members of the anaerobic microbiota in the oral cavity, utilize lactate.

What oral and dental complications are associated with Veillonella species?

Dental plaque, dental caries, periodontal disease, halitosis, and endodontic infections.

What are the most common Gram-negative bacilli causing oral complications?

Fusobacterium species, Prevotella intermedia, Porphyromonas gingivalis.

What are the characteristics of Fusobacterium species?

Gram-negative anaerobic bacilli commonly found in the human oral cavity.

What oral and dental complications are associated with Fusobacterium species?

Periodontal disease, dental plaque and biofilm formation, endodontic infections, oral cancer association, and halitosis.

What are the characteristics of Prevotella intermedia?

Anaerobic Gram-negative bacilli.

What oral and dental complications are associated with Prevotella intermedia?

Dental plaque and biofilm formation, endodontic infections, halitosis, and periodontal disease, pregnancy-associated gingivitis and ANUG.

What are the characteristics of Porphyromonas gingivalis?

Anaerobic Gram-negative bacilli, commonly found in periodontal pockets.

What oral and dental complications are associated with Porphyromonas gingivalis?

Chronic periodontitis, gingivitis, bone loss, involvement in root canal infections, periapical abscesses, and halitosis.
