|
170 patients attending the
Oral and Maxillofacial Surgery Clinic of the University of
Benin Teaching Hospital, Benin City, Nigeria, were screened
bacteriologically, to determine the prevalence of
bacteraemia following dental extraction procedures. 5 ml of
blood was collected from each patient before and after the
extraction. Post-operative bacteraemia occurred in 55
(32.4%) of the 170 patients screened. 61 (78.2%) of the 78
isolates obtained in the survey were facultative anaerobes
while 17 (21.8%) were obligate anaerobes. Amongst the
facultative anaerobes, the most frequently isolated
bacterial genus was Staphylococcus (19, 24.4%)
followed by Streptococcus spp. (16, 20.5%) and
α-haemolytic Streptococcus spp. (10, 12.8%).
Bacteriodes spp. (8, 10.3%) was the most frequently
isolated anaerobe followed by Peptostreptococcus spp.
(5, 6.4%) and clostridium spp. (4, 5.16%). The
occurrence of bacteriaemia increased with duration of
extraction and number of teeth extracted. It also occurred
more frequently when teeth were extracted because of
inflammatory dental disease.
Key words:
