“…In our study, patients were selected with platelet count not less than 50.000/mm 3 and absolute neutrophil counts not less than 1000/mm 3 to avoid the high bleeding tendency and opportunistic infections, this selection criterion followed the study of Dibiase in 1983 who stated that the aggressiveness of oral care must be compatible with the status of the patient's bone marrow. The patient's oral hygiene can be maintained if the platelet count is greater than 50,000/mm 3 and the granulocyte count is at least 1000/ mm 3 , when the platelet count is below 50,000/mm 3 , the use of floss, toothpicks, and water irrigating devices are contraindicated due to their potential for producing local trauma [14].…”
