OBJECTIVE: To find out the relationship between recurrent aphthous stomatitis (RAS) with deficiencies of haemoglobin, haematocrit, serum vitamin B12, serum Ferritin and red blood cells (RBC) Folate level. STUDY DESIGN: An analytical cross-sectional study. PLACE AND DURATION OF STUDY: Department of Oral Health Sciences, Shaikh Zayed Federal Postgraduate Medical Complex, Lahore, from February to July 2008. METHODOLOGY: Sixty consecutive subjects with active RAS were taken as the aphthous group; 60 age and gender matched subjects without RAS were as the Non-Aphthous group. Five milliliter blood was taken from both groups to evaluate the levels of serum B12, and RBC Folate through radio immuno assay and serum ferritin with enzyme linked immuno-sorbent assay tests. Complete blood count was carried out to determine the level of haemoglobin and haematocrit in both groups. Proportion of subjects with lower values was compared using 2 text of proportions with significance at p < 0.05. RESULTS: Serum Ferritin (p = 0.001), haematocrit (p < 0.001), RBC Folate (p < 0.001) and serum B12 (p < 0.001) were significantly lower in the RAS group. Combined deficiency state (haemoglobin, serum Ferritin, haematocrit, RBC Folate and serum B12) was identified in 13% (n = 8) RAS patients. CONCLUSION: Frequency of haematinic deficiencies was high in RAS patients. Serum B12 and RBC Folate were significantly low in aphthous group.
