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]
Botryoid odontogenic cyst (BOC) is a type of developmental odontogenic cyst that is extremely rare. [1] It is thought to be a lateral periodontal cyst (LPC) variant with a higher risk of recurrence. [2] Weathers and Waldron coined the term BOC in 1973. [3] Adults over the age of 50 are the most affected. [4]
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 .
Dental abscess; Other names: Dentoalveolar abscess, Periapical abscess, tooth abscess, root abscess: A decayed, broken down tooth, which has undergone pulpal necrosis.A periapical abscess (i.e. around the apex of the tooth root) has then formed and pus is draining into the mouth via an intraoral sinus ().
Odontogenic cysts are a group of jaw cysts that are formed from tissues involved in odontogenesis (tooth development). Odontogenic cysts are closed sacs, and have a distinct membrane derived from the rest of odontogenic epithelium. It may contain air, fluids, or semi-solid material.
The formative role of the dental follicle starts when the crown of the tooth is fully developed and just before tooth eruption into the oral cavity. [2]Although tooth eruption mechanisms have yet to be understood entirely, generally it can be agreed that many factors, together, affect the tooth eruption process which is why it is very difficult to differentiate the causes and effects. [3]
The epithelial cell rests of Malassez presented in the roots surface, principal location of the LPC, play a role in LPC formation. [8]Several additional theories had been proposed regarding the origin of lateral periodontal cysts, including the possibility that the lesions may arise as a result of pulpal infection manifesting itself in a lateral position or chronic periodontal disease ...
Consequently, a new classification was developed at the International Workshop for a Classification of Periodontal Diseases and Conditions in 1999. This covered in much more detail the full range of periodontal diseases. "Adult periodontitis" was reclassified "chronic periodontitis" and "early-onset periodontitis" to "aggressive periodontitis".
