Previous issue date: 2010-02-18 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Bone marrow transplantation (BMT) is currently the best therapeutic option for patients with hematologic diseases, solid tumors or autoimmune disorders. It is characterized by intravenous infusion of hematopoietic stem cells in order to restore marrow function. However, this procedure requires concomitant immunosuppression treatment, which favors the development of certain complications, often manifested in the oral cavity. This study aimed to evaluate the incidence of oral changes in patients undergoing BMT and to correlate these results with clinical aspects related to the patients and the transplants performed. This is a prevalence study, with cross-sectional design, carried out in a BMT service at the Institute of Onco-Hematology of Natal (ION) and Natal Hospital Center. Data collection was based on questionnaires, clinical examination of the oral cavity and consultation in the medical records. The sample consisted of 51 patients undergoing BMT. After the analysis, was found a general status with good health conditions and presence of oral changes in about half of patients who composed the sample. The manifestations observed were, in decreasing order of frequency: mucositis; gingival alteration and thrombocytopenic purpura; mucosal pigmentation; lichenoid reaction and candidiasis. The oral changes were observed more frequently in cases of allogeneic TMO, in different periods post-transplant, without significant differences related to the source of cells. It was found statistically significant association between the presence of graft-versus-host disease (GVHD) and oral changes (p < 0,001). Therefore, it is concluded that there is a relatively high incidence of changes in oral cavity of patients receiving bone marrow transplantation, a fact which confirms the need to consider this site for examination, diagnosis, treatment and prognosis of possible complications of BMT / O transplante de medula ?ssea (TMO) atualmente constitui a melhor op??o terap?utica para pacientes com doen?as hematol?gicas, tumores s?lidos ou desordens autoimunes. Caracteriza-se pela infus?o intravenosa de c?lulas progenitoras hematopo?ticas com o objetivo de restabelecer a fun??o medular. No entanto, esse procedimento requer tratamento concomitante de imunossupress?o, o que favorece o desenvolvimento de determinadas complica??es, as quais freq?entemente se manifestam na cavidade oral. Este estudo objetivou avaliar a incid?ncia de altera??es orais em pacientes submetidos ao TMO e correlacionar esses resultados com aspectos cl?nicos referentes aos pacientes e aos transplantes realizados. Trata-se de um estudo de preval?ncia, com desenho do tipo seccional, realizado no servi?o de TMO do Instituto de Onco-Hematologia de Natal (ION) e Natal Hospital Center. A coleta de dados baseou-se em aplica??o de question?rio, exame cl?nico da cavidade oral e consulta de informa??es nos prontu?rios m?dicos. A amostra foi constitu?da por 51 pacientes submetidos ao TMO. Ap?s a an?lise, constatou-se quadro geral com boas condi??es de sa?de e presen?a de altera??es orais em aproximadamente metade dos pacientes que compunham a amostra. As manifesta??es observadas foram, em ordem decrescente de frequ?ncia: mucosite; altera??o gengival e p?rpura trombocitop?nica; pigmenta??o da mucosa; rea??o liquen?ide e candid?ase. As altera??es orais foram mais frequentes em casos de TMO alog?nico, em diferentes per?odos p?s-transplantes, sem diferen?a significativa quanto ? origem das c?lulas. Constatou-se associa??o estatisticamente significante entre a presen?a de doen?a do enxerto contra hospedeiro (DECH) e altera??es orais (p < 0,001). Portanto, conclui-se que h? uma incid?ncia relativamente alta de altera??es na cavidade oral de pacientes transplantados de medula ?ssea, fato que confirma a necessidade de se considerar a import?ncia desse s?tio para exame, diagn?stico, tratamento e progn?stico de poss?veis complica??es do TMO
