Oral health status in adult patients with newly diagnosed acute leukemia

Abstract

Background

The aim of this cross-sectional study was to evaluate the oral health of adult patients with newly diagnosed acute leukemia.

Methods

Patients with initially diagnosed acute myeloid (AML) or lymphocytic (ALL) leukemia and a matched healthy control (HC) group were included. The oral investigation comprised inspection of the oral mucosa; the decayed (D), missing (M), and filled (F) teeth (DMF-T) index; and a detailed periodontal status. Subgingival biofilm samples were analyzed (polymerase chain reaction) for the presence of selected potentially periodontal pathogenic bacteria. Statistical analysis was performed using Fisher's exact test, chi-squared test, and Mann-Whitney U test (significance level α = 5%).

Results

Thirty-nine patients with leukemia (AML 26, ALL 13) and 38 HCs were included. Oral mucosal findings were present in 62% of L compared to 0% of HC patients, whereby gingival hyperplasia was the most detected finding. Furthermore, a higher caries prevalence in leukemia patients was shown (D value 3.64 ± 3.98 vs. 0.72 ± 1.72, p < 0.01). The periodontal parameters were poorer in leukemia patients. No substantial differences in microbiological findings of selected bacteria were detected within L group and between L and HC patients.

Conclusion

The high prevalence of oral diseases supports the demand of an early and consequent dental treatment of leukemia patients, especially considering subsequent therapy.
