Chewing fails to induce oral bacteraemia in patients with periodontal disease

Abstract

Chewing did not cause bacteraemia in chronic periodontitis or plaque-induced gingivitis patients and may not be a risk factor for infective endocarditis in at-risk individuals with periodontal disease.

Analysis of systemic and local odontogenic infection complications requiring hospital care

“…1,2 Other studies show, however, that also non-invasive and moderately invasive dental manipulations, such as restorative treatment and removal of dental plaque and calculus, and even normal daily dental activities can cause a significant bacteraemia, especially if made on chronically infected sites, 32 although contradictory results do exist. 35,36 Tooth extractions were the major cause for local spread of the infection in this study. However, in cases of systemic infection complications none of the preceding dental procedures could be distinguished as a high-risk procedure.…”

Incidence and magnitude of bacteraemia caused by flossing and by scaling and root planing

“…Other activities such as chewing may also contribute to daily bacteraemia (Fine et al 2010). However, there is inconsistency in relation to chewing-induced bacteraemia with recent studies of subjects with gingivitis reporting a 35% incidence (Fine et al 2010) or nil incidence (Forner et al 2006, Murphy et al 2006) and studies of chronic periodontitis reporting a nil incidence (Murphy et al 2006) and a 13% incidence (Forner et al 2006).…”

Periodontitis as a Risk Factor of Atherosclerosis

“…In another study [58], an increased level of dental plaque bacteria in blood circulation after dental plaque removal and tooth extraction were described. On the other hand, chewing did not cause bacteremia in chronic periodontitis patients [59]. …”
