The efficacy of two different oral hygiene regimens on the incidence and severity of oral mucositis in pediatric patients receiving hematopoietic stem cell transplantation: A prospective interventional study.

Aims: This prospective interventional study aimed to assess the efficacy of supersaturated calcium phosphate rinse and the use of an extra-soft toothbrush twice a day when added to the existing oral hygiene protocol regimen (0.12% chlorhexidine gluconate + 3% sodium bicarbonate + nystatin 5000 U/mL) in reducing the severity of oral mucositis among pediatric patients receiving chemotherapy for the hematopoietic stem cell transplant.

Methods: Forty-five patients that received chemotherapy for the hematopoietic stem cell transplant were randomly allocated to three groups of 15 patients each. Group A was advised to follow the existing oral hygiene protocol regimen (Control), group B was advised to brush their teeth twice daily using an extra-soft toothbrush and to follow the control regimen, and lastly group C was advised to use supersaturated calcium phosphate rinse and to follow the control regimen. Oral mucositis was recorded according to World Health Organization criteria from the day of admission (day 1) to the day of discharge (day 28). The incidence of oral mucositis between the three groups was compared using the Kruskall-Wallis test while the severity of oral mucositis between the three groups was compared using a one-way ANOVA test.

Results: The results of the study showed no significant difference in the incidence of oral mucositis between the three groups; however, there was a lower severity of oral mucositis in the supersaturated calcium phosphate rinse group when compared to the control group or the group who used an extra-soft toothbrush with the control regimen.

Conclusion: Although marginally fewer cases and lower severity of oral mucositis was observed in the group using supersaturated calcium phosphate rinse, the lack of statistical significance suggests that the evidence for their use is not conclusive. The results of this study also showed that the introduction of an extra-soft toothbrush into the oral hygiene regimen did not significantly reduce the incidence of oral mucositis and may actually be responsible for an increase in the severity of oral mucositis.
