Abstract
There is a possibility that bacteria may enter the blood stream during some non-surgical manipulation procedures, which include orthodontic treatment procedures (alginate impression taking, separator placement, band cementation, and archwire change). The aim of this study was to determine the prevalence and intensity of bacteraemia associated with orthodontic procedures in patients seen at the Lagos University Teaching Hospital, Nigeria. A total of 100 subjects who presented at the Orthodontic Clinic of the Lagos University Teaching Hospital and who met the inclusion criteria were recruited for the study. Four orthodontic procedures were investigated: alginate impression taking, separator placement, band cementation and archwire placement. Subjects were randomly placed in one of the four procedure groups. Peripheral blood was collected for microbiologic analysis before the orthodontic procedures and within 2 min of completion of the procedures. The BACTEC automated blood culture system and the lysis filtration method of blood culturing were used for microbiological analysis of the blood samples. The Wilcoxon signed rank test, the McNemar χ(2) test, the Mann-Whitney U-test, and Spearman and point bi-serial correlations were used...Continue Reading
