Periodontics
In the early stages of dental plaque formation, particularly within the first
few days, the predominant microorganisms are typically cocci, especially Streptococcus species.
These bacteria are among the first to colonize the tooth surface after a
cleaning, forming a biofilm. Thus, in a two-day-old dental plaque, the majority of microorganisms will
indeed be cocci

Oral PathologyMyositis ossificans generalisata (fibrodysplasia ossificans progressiva) causes progressive ossification of muscles, tendons, and ligaments, leading to a "petrified" or stone-like condition where the patient becomes immobilized. This rare genetic disorder progressively restricts movement as soft tissues calcify. Dystrophic myotonia, dermatomyositis, and proliferative myositis do not cause this petrification process.
