摘要
To assess halitosis parameters using OralChroma™ and the correlation with salivary flow, oral hygiene index, radiation dose, and tongue-coating index among irradiated head and neck cancer patients compared to patients without cancer.This cross-sectional study enrolled irradiated and non-irradiated patients divided into two groups. Hydrogen sulfide, methyl mercaptan, and dimethyl sulfide (DMS) levels were measured using a gas chromatograph, and sialometry was performed. The tongue-coating index and simplified oral hygiene index were also assessed.Thirty-eight patients were allocated to each group. Volatile sulfur compound levels were above the thresholds in both groups. Non-irradiated individuals showed higher levels of hydrogen sulfide and dimethyl sulfide. Patients with asialia had an inexpressive tongue-coating index and increased dimethyl sulfide levels. A decrease in salivary flow rate was followed by a significant increase in volatile sulfur compound levels. Higher doses of radiation to the submandibular salivary glands were associated with higher concentrations of sulfide and methyl mercaptan.Head and neck radiotherapy may be important in the development of halitosis. Irradiated patients with asialia presented insignificant lingual biofilm. Consequently, lower levels of volatile sulfur compounds were detected in this group. Asialia, a severe radiation-induced hyposalivation, impacted the levels of DMS (extraoral origin).
