Insights
Pediatric patients with neutropenia reported more mouth sores and bleeding gums. However, clinical examinations revealed no increased risk of oral diseases compared to healthy children.
Area of Science:
- Pediatric Dentistry
- Hematology
- Oral Medicine
Background:
- Neutropenia, a condition characterized by low neutrophil counts, can impact overall health.
- Children with neutropenia often require specialized medical care, including management by a hematologist.
- The oral health implications for pediatric patients with neutropenia are not fully understood.
Purpose of the Study:
- To compare the oral health status of children with neutropenia to a healthy control group.
- To identify potential oral health risks associated with neutropenia in pediatric patients.
- To assess the need for specific dental care protocols for children undergoing hematological treatment.
Main Methods:
- A cross-sectional study design was employed.
- Participants included children aged 6-18 with neutropenia and a healthy control group.
- Data collection involved patient questionnaires and comprehensive dental and radiographic examinations.
Main Results:
- Neutropenia patients reported significantly higher rates of mouth sores and gum bleeding.
- The neutropenia group exhibited a significantly lower dmft/t score (decayed, missing, filled teeth).
- Clinical assessments showed no significant differences in ulcerations, gingival health, periodontal status, or hygiene indicators between groups.
Conclusions:
- While subjective reports indicate increased oral discomforts like sores and bleeding in children with neutropenia, objective clinical findings do not support an elevated risk for common oral diseases.
- Pediatric patients actively managed by hematologists for neutropenia may not have a higher prevalence of dental caries or periodontal issues compared to healthy peers.
- Further research is warranted to explore the nuances of oral health management in this vulnerable pediatric population.
Abstract:
The purpose of this cross-sectional study was to assess and compare the oral health of children with neutropenia, who are under the active care of a hematologist in a designated marrow failure and myelodysplasia program, to a healthy control group. Children aged 6-18 with neutropenia attending the Marrow Failure and Myelodysplasia Program at SickKids Hospital and controls attending the Children's Clinic, Faculty of Dentistry, University of Toronto were asked to participate in the study consisting of a patient questionnaire followed by a dental and radiographic examination. Fifteen patients with neutropenia (mean age 12.14 ± 4.04 years) and 26 healthy controls (mean age 11.61 ± 3.82 years) participated in this study. Patients with neutropenia reported significantly increased mouth sores (p < .008) and bleeding gums while brushing (p < .001). The dmft/t score was significantly lower for the neutropenia group (p < .009). The clinical examination also showed that there were no statistically significant differences with respect to ulcerations, gingival recession, tooth mobility, gingival inflammation, periodontal bone loss, DMFT/T scores, plaque, and calculus levels. Preliminary data demonstrates that pediatric patients who are under the active care of a hematologist do not present with an increased risk of oral diseases.
