Although rare, mouth infections may also spread through the nasal and facial veins that drain into a reservoir of deoxygenated blood called the cavernous sinus. Once the infection has spread to the cavernous sinus, it can compress important nerves ( cranial nerves III, IV, V1, V2, and VI ) within this space and obstruct venous drainage from the ...
Odontogenic infections can be severe if not treated and are associated with mortality rate of 10 to 40%. [4] Furthermore, about 70% of odontogenic infections occur as periapical inflammation, i.e. acute periapical periodontitis or a periapical abscess. [3] The next most common form of odontogenic infection is the periodontal abscess. [3]
Also infection can spread down the tissue spaces to the mediastinum which has significant consequences on the vital organs such as the heart. Another complication, usually from upper teeth, is a risk of sepsis traveling through pathways to which it can possibly lead to endocarditis , brain abscess (extremely rare), or meningitis (also rare).
Periapical periodontitis may develop into a periapical abscess, where a collection of pus forms at the end of the root, the consequence of spread of infection from the tooth pulp (odontogenic infection), or into a periapical cyst, where an epithelial lined, fluid-filled structure forms.
Toothache may be caused by dental (odontogenic) conditions (such as those involving the dentin-pulp complex or periodontium), or by non-dental (non-odontogenic) conditions (such as maxillary sinusitis or angina pectoris). There are many possible non-dental causes, but the vast majority of toothache is dental in origin.
Odontogenic infections which erode through the buccal cortical plate of the mandible or maxilla will either spread into the buccal vestibule (sulcus) and drain intra-orally, or into the buccal space, depending upon the level of the perforation in relation to the attachment of buccinator to the maxilla above and the mandible below (see diagrams).
Odontogenic sinusitis is a type of sinusitis (inflammation of the sinuses), specifically caused by dental infections or procedures. [1] Comprising approximately 10-12% of all chronic sinusitis cases, this condition primarily affects the maxillary sinus , which is in close proximity to the upper teeth .
Transmissibility is the probability of an infection, given a contact between an infected host and a noninfected host. [8] Community transmission means that the source of infection for the spread of an illness is unknown or a link in terms of contacts between patients and other people is missing. It refers to the difficulty in grasping the ...
