41 An analysis of the rates of OTM observed in this study showed that the observed rate of 1.2mm/mos of OTM for both control and LED treated teeth were consistent with previously published effects of LLLT on OTM and on OTM in general. This finding demonstrates that the patients of this study and the mechanics used for extraction space closure were consistent and comparable with that of previous literature. A close analysis of the OTM rates showed that the study sample had a wide range of starting extraction space sizes when categorized by those treated on round wires versus rectangular wires. This finding was not of importance as it was the rate of OTM (the slope of the lines in Results, Figure 3.4) that was determined to not show any difference from the LED phototherapy application. Further analysis also demonstrated that one LED phototherapy treated canine did not exhibit space closure during the T0-T1 phase. This observation was not expected. It is possible that the orthodontic biomechanics of this patient were altered by influences beyond the control of the study. It is possible that friction levels between the archwire and bracket (eg., from accumulations of calcified food debris or distortions of the orthodontic wire) may have been increased momentarily, preventing tooth movement. However, this patient subsequently showed tooth movement in the T1-T2 treatment phase. Perhaps this patient underwent an unusually long hyalinization period once a retraction force was applied to the tooth. However, this would not be expected as this phenomenon was not seen on the control side. In an attempt to account for this data as illegitimate, a separate data analysis was done without this data set. This did not alter the findings of no effect of IR-LED phototherapy on the rate of OTM and thus was not removed from the total sample.PDF Image | Effect of LED Phototherapy on the Rate of Orthodontic Tooth Movement
