[A primary analysis of oral mucosa and periodontal status of chronic graft-versus-host disease caused by hematopoietic stem cell transplantation].

Purpose: The aim of this study was to investigate the severity and status of oral mucosa and periodontal status in early and late stage after receiving hematopoietic stem cell transplantation(HSCT).

Methods: This study enrolled patients submitted to hematopoietic stem cell transplantation. Through a survey questionnaire, clinical examination, we collected clinical data from 108 HSCT recipients and divided them into 2 groups: transplantation time less than 1 year and more than 1 year. The oral mucosal and periodontal status were recorded and statistically analyzed with SPSS 21.0 software package.

Results: The incidence of oral features after HSCT was 78.95%. The incidence of mild symptoms with HSCT less than 1year (n=32) and HSCT more than 1 year (n=43) was 59.38% and 18.60%, respectively. There was significant difference between the two groups (P=0.001).The percent of lichenoid/hyperkeratotic plaques was 31.25% and 60.47%, respectively. The lichenoid/hyperkeratotic plaques were significantly different between the two groups (P=0.012). The detection rate of shallow and moderate pockets was 49.38% and 40.74%, respectively. Visual plaque, calculus and bleeding on probing were 62.96%, 64.20% and 50.62%, respectively.

Conclusions: The incidence of periodontal and mucosal lesions after HSCT is high. The mild symptoms of oral graft versus host disease in early stage are identified obviously, mainly like lichenoid/hyperkeratotic plaques in late stage.
