- Radboud University Medical Center
- Brief Summary
Haematopoietic stem cell transplantation (HSCT) is a potentially lifesaving treatment option for various diseases. It involves infusion of stem cells after a conditioning regimen of chemotherapy with or without total body irradiation. There is a concern that HSCT and accompanying treatments may increase the risk for oral complications. Nevertheless, longitudinal studies measuring oral health before and after HSCT are scarce. Hence, we formulated the following research question:
In adult HSCT recipients, do oral health parameters change from baseline (pre-HSCT) to 3 - 24 months post-HSCT, and is the type of conditioning regimen associated with this change in oral health parameters?
To answer this research question, we will use data from the electronic health records of the Radboudumc (Epic and Dentium). We will include at least seventy-five adult patients who are examined both before and after HSCT at the department of Dentistry (Radboudumc) as part of an oral care program. The following oral health parameters were assessed: status praesens, pocket probing depth, bleeding on probing, periodontal epithelial surface area, periodontal inflamed surface area, xerostomia, unstimulated and stimulated salivary flow rate and pH, cariesactivity, oral chronic Graft-versus-Host Disease and dental treatments.
Patients were subjected to different regimens in preparation for HSCT, namely myeloablative, reduced intensity or non-myeloablative conditioning. To estimate the association between conditioning regimen and the change in oral health parameters, we will use mixed effects models with random effects, adjusted for potential confounders. Results will be reported as regression coefficients with corresponding 95% confidence intervals.

- Primary Outcome Measures
Name Time Method Unstimulated and chewing stimulated salivary pH Change from baseline (pre-HSCT) up to 24 months after HSCT Whole mouth saliva, measured with pH strips
Pocket probing depth Change from baseline (pre-HSCT) up to 24 months after HSCT Pocket probing depth at 6 sites per tooth in millimetres
Number of restorations Change from baseline (pre-HSCT) up to 24 months after HSCT Total number of restored tooth surfaces
Bleeding on probing Change from baseline (pre-HSCT) up to 24 months after HSCT Profound bleeding on probing at 6 sites per tooth as yes or no
Number of teeth Change from baseline (pre-HSCT) up to 24 months after HSCT Number of teeth (range 0 - 32)
Unstimulated and chewing stimulated salivary flow rate Change from baseline (pre-HSCT) up to 24 months after HSCT Whole mouth saliva, measured in mL/min
- Secondary Outcome Measures
Name Time Method Periodontal Epithelial Surface Area Change from baseline (pre-HSCT) up to 24 months after HSCT The root surface area in square millimetres affected by attachment loss
Oral chronic Graft-versus-Host Disease Up to 24 months after HSCT Assessed with National Institute of Health Oral Mucosal Score (range 0 - 15), higher score means more severe oral manifestations of oral chronic Graft-versus-Host Disease
Periodontal Inflamed Surface Area Change from baseline (pre-HSCT) up to 24 months after HSCT The root surface area in square millimetres affected by attachment loss and inflamed periodontal tissue
Cariesactivity Up to 24 months after HSCT Likelihood for development of new caries lesions based on notes recorded by the dentist
Extractions Between baseline (pre-HSCT) and up to 24 months after HSCT Total number of removed teeth (range 0 - 32)
Periodontal care Between baseline (pre-HSCT) and up to 24 months after HSCT Number of participants per type of periodontal care, categorised in sub- and supragingival cleaning, subgingival cleaning, no cleaning
Xerostomia Change from baseline (pre-HSCT) up to 24 months after HSCT Subjective oral dryness measured by Xerostomia Inventory questionnaire
Preventive measures Between baseline (pre-HSCT) and up to 24 months after HSCT Number of participants per type of preventive measure as fluoride varnish and oral hygiene instructions
