Evaluation of halitosis and sialometry in patients submitted to head and neck radiotherapy.

Objectives: The aim of this study was to investigate the parameters of halitosis and sialometry in patients who had undergone head and neck radiotherapy, correlating oral concentration of volatile sulfur compounds (VSC) with the presence of tongue coating, salivary flow rate and BANA test.

Material And Methods: 35 patients allocated in two groups were examined: group I (control)--patients with systemic and oral health; group II--patients submitted to head and neck radiotherapy. All volunteers were submitted to halitosis measurements through a sulphide monitor, evaluation of tongue coating weight, non-stimulated sialometry and BANA test.
