Objectives: The objective of the present study is to assess whether a good buccodental status (evaluated by means of dentogingival indices), is associated with a lower incidence and severity of oral mucositis in patients with hematological diseases who receive treatment with chemotherapy or bone marrow transplant. Study design: The study was carried out on 97 patients admitted to the Hematology Service of the Hospital Duran y Reynals in Barcelona during 2002-2003. These patients received treatment with chemotherapy or conditioning prior to bone marrow transplant. A descriptive study was made, analyzing oral hygiene, one dental index, and two gingivales indices, and evaluating their relationship with the appearance of mucositis. Results: The patients with high plaque (PI) and gingival (GI) indices during chemotherapy presented a higher percentage of mucositis (77.4% and 65.7% respectively) against those who had little or no visible plaque. In the case of the PI, the differences were statistically significant (p=0.015). Likewise, patients who brushed their teeth 3 times/day presented mucositis in only 26.7% of cases, against those who did not brush, or brushed only once a day (65.9% and 68.4%), these differences also being statistically significant (p=0.013). The CAO showed similar results in patients with or without mucositis (7.59 and 7.03 respectively). Conclusions: In our study, a good gingival status as well as good oral hygiene during chemoradiotherapy is associated with a lower incidence and severity of mucositis.
