Abstract

Objective: The aim of this study was to investigate the later oral consequences of chemotherapy on the oral health of children with emphasis on the cariological status and the major and minor salivary gland function.Method: Thirty-eight 12-year-old children (mean age 12.3 ± 0.58 years) who underwent chemotherapy were evaluated after 5 years of treatment. Forty age- and sex-matched healthy children with similar socioeconomic backgrounds served as controls. Subjects' cariological status was explained by the number of decayed, filled, missing permanent teeth (DMF-T), and unstimulated and stimulated whole saliva flow rates were measured by the spitting method. Palatal saliva flow rate using a Periotron meter (Oraflow Inc., Plainview, NY) and salivary buffer capacity using CRT buffer (Ivoclar Vivadent AG, Schaan, Lichtenstein) were also investigated.Results: Children who underwent chemotherapy had significantly more decayed teeth than healthy controls (3.97 ± 3.58 vs 0.84 ± 1.75, respectively, p < 0.001). Recipients of chemotherapy had significantly lower stimulated whole saliva flow rate (0.84 ± 0.35 vs 1.13 ± 0.46 ml/min, p < 0.05) compared to the controls. Palatal saliva flow rate was at the same time significantly higher in the test group compared to the controls (1.64 ± 0.87 vs 0.46 ± 0.32 ml/min/cm2, respectively, p < 0.001). High levels of buffer capacity of the saliva could be detected in a significantly higher prevalence in the patient group compared to the controls (high: 81.6% vs 40%).Conclusions: According to these results, chemotherapy in children might result in a decreased stimulated whole saliva flow rate, hyposalivation, and, consequently, increased caries risk. Although these processes might be compensated to a limited extend by the increased minor saliva flow rate, resulting in a higher buffer capacity, nutrition and oral hygiene control of children obtaining cancer therapy is essential in the preservation of the oral tissues.
