Hematopoietic stem cell transplantation patients frequently develop oral mucositis, gingivitis, and ulcers. Early oral disease management is crucial for reducing complications after transplantation.
Area of Science:
- Oral medicine
- Hematology
- Transplantation immunology
Background:
- Hematopoietic stem cell transplantation (HSCT) involves intensive chemotherapy and radiotherapy, leading to severe immunosuppression.
- This immunosuppression significantly increases the risk of oral complications in patients.
Purpose of the Study:
- To establish an oral disease management protocol for patients before and after hematopoietic stem cell transplantation.
- To assess the incidence and severity of oral conditions during the transplantation process.
Main Methods:
- A prospective study involving 65 adult patients with hematological diseases undergoing HSCT (34 allogeneic, 31 autologous).
- Three dental assessments were conducted: pre-transplantation, one week post-infusion, and 100 days post-transplantation.
- Oral changes were scored and categorized by risk level (mild, moderate, severe).
Main Results:
- The most common oral conditions observed were mucositis, gingivitis, pericoronitis, and ulcers.
- Oral mucositis, linked to immunosuppressive drug toxicity, was the predominant disease at one week and 100 days post-transplantation.
- Gingivitis and ulcers were frequent findings during the later assessment period.
Conclusions:
- Oral mucositis significantly increases the risk of clinical complications in HSCT patients.
- Gingivitis, ulcers, and pericoronitis are also identified as potential risk factors for adverse clinical outcomes.
- A structured oral care protocol is essential for managing these complications.
