Description:
The dontogenous infection - an infection which entrance gate is tooth and is more right a periodontium.
Symptoms of the Dontogenous infection:
The dontogenous infection is characterized by four classical symptoms: temperature increase (calor), pain (dolor), reddening (rubor) and swelling (tumor). Usually the infection begins with emergence of a swelling which gradually accrues. Patients complain of dull ache and unpleasant taste in a mouth. The infection can be delimited for a long time, being shown by the minimum symptomatology, or to progress, leading to development of abscess, a parulis, phlegmon. Abscess — the cavity containing pus and necrotic fabrics it is accurately delimited from surrounding fabrics. Symptoms of abscess can be expressed as outside, and from an oral cavity. Drainage of abscess at out of time executed section can spontaneously result from its break. Parulis reminds abscess, differing from it in the fact that pus is drained through the fistular course opening on a mucous membrane a yellow-red papule. In most cases парулис represents persistent infection and does not disturb patients. Phlegmon — a precursory symptom of spread of a dontogenous infection, is shown by diffusion inflammatory reaction and lack of a clear boundary. Phlegmon is shown by the diffusion swelling which is usually localized in a cheek or a mandible, reddening, increase in local temperature, dense hypostasis and morbidity of soft tissues. Phlegmon can be delimited with formation of abscess and the subsequent its break or extend to the neighboring anatomic areas, overcoming fascial barriers. In this case it is about phlegmon of a fasnialny bed.
Reasons of the Dontogenous infection:
In most cases the pulp necrosis, furrowed and apical periodontitis and a pericoronitis happens the reason of a dontogenous infection. Almost in all cases at a dontogenous infection from the center of defeat sow the mixed microflora: in 65% of cases — anaerobic bacteria, in 35% of cases — aerobic. Most often reveal strict gram-negative anaerobes (Bacteroides spp., Fusobacterium spp.), anaerobic gram-positive bacteria (Peptostreptococcus spp.) and optional anaerobic gram-positive streptococci (for example, Streptococcus milleri). From other causative agents of a dontogenous infection it is necessary to specify Lactobacillus spp., Diphtheroides spp., Actinomyces spp., Eikenella spp. Usually these activators find resistance to one or several often applied antibiotics.
Treatment of the Dontogenous infection:
Treatment of a dontogenous infection includes: 1) elimination of a source of an infection, 2) ensuring effective outflow, 3) appointment in need of antibiotics, 4) a symptomatic treatment. Processing of the root channel or removal of the affected tooth when the center of an infection is delimited (for example, at a parulisa, apical periodontitis), provides drainage of exudate and often leads to permission of phlegmon. If necessary for more effective drainage abscess is opened. If pyoinflammatory process in the center of an infection is not localized as, for example, at a pericoronitis, performance of a section is usually inefficient and is not recommended. For treatment of the phlegmon caused by impractical tooth it is necessary to process the root channel or to extract impractical tooth.
