Prevalence, intensity and nature of bacteraemia after toothbrushing

Abstract Objective To estimate the prevalence, intensity and microbial identity of bacteraemia associated with toothbrushing. Methods A total of 141 children and adolescents, aged between 3 and 17 years, having dental treatment under general anaesthesia at the Eastman Dental Hospital were recruited....

description Abstract Objective To estimate the prevalence, intensity and microbial identity of bacteraemia associated with toothbrushing. Methods A total of 141 children and adolescents, aged between 3 and 17 years, having dental treatment under general anaesthesia at the Eastman Dental Hospital were recruited. Six millilitre of blood was taken before toothbrushing (baseline) with (1) Oral B 30 toothbrush or (2) Braun or (3) Sonicare electric toothbrush or (4) dental handpiece and rubber cup. A second 6-ml sample was taken 30 s after toothbrushing. All blood samples were processed using lysis filtration and bacteria were identified to species level. Results There was a significantly greater prevalence of bacteraemia following the dental handpiece only ( p = 0.02). There was a significantly greater aerobic and anaerobic intensity of bacteraemia following brushing with both the Sonicare ( p = 0.03 and p = 0.05) and the dental handpiece ( p = 0.001 and p = 0.005). Conclusions Toothbrushing causes a bacteraemia that is often statistically significantly greater than baseline. Toothbrushing is an important contributory factor in cumulative dental bacteraemia.
