Aims:
To evaluate neutrophil myeloperoxidase (MPO) staining procedure as a reliable, affordable and easily available diagnostic assay for aggressive periodontitis.
Materials And Methods:
Fifteen subjects were recruited in the study wherein five each were diagnosed as aggressive periodontitis and chronic periodontitis respectively, and five were periodontally healthy. Three millilitres (ml) of venous blood was collected using Vacutainers containing ethylene diamine tetra acetate (EDTA) and was subjected to MPO staining procedure. Histological picture was evaluated using a visual analogue scale (VAS).
Results:
MPO stained specimen of all the patients showed positive MPO staining of the neutrophils. The intensity of the stain of MPO granules was more in aggressive periodontitis specimen as compared to the chronic periodontitis patient specimen and healthy subject specimen. The staining characteristics were comparable for chronic periodontitis patients and healthy subject.
Conclusions:
This study shows that there is a potential and probable place for MPO staining as an economical, relatively convenient and easily available assay in the diagnosis of aggressive periodontitis.
