Introduction. Orofacial pain occurs in various disorders of the orofacial
region. Objective. The aim of this study was to examine applicability of the
visual-analogue scale (VAS) in patients with orofacial pain (model of acute
and chronic pain). Methods. The study involved 60 patients, aged 18-70 years.
The first group consisted of patients with dentin hypersensitivity, and the
second group of patients with chronic rhinosinusitis. All patients were asked
to fill-in a pain questionnaire and to rate pain intensity on the modified
visual analogue scale (VAS; 0-10). Air indexing method was performed in the
patients with dentin hypersensitivity in order to provoke pain, while the
patients with chronic rhinosinusitis underwent CT imaging of paranasal
sinuses. Wilcoxon’s test and Pearson’s correlation coefficient were used for
statistical analysis. Results. In patients with dentin hypersensitivity
provocation increased subjective feeling of pain, but without statistical
significance (t=164.5; p>0.05). In patients with chronic rhinosinusitis a
significant statistical correlation (r=0.53; p<0.05) was found between
subjective pain assessment of VAS and CT findings. Conclusion. Applying VAS
in the evaluation of acute and chronic pain can indicate progression or
regression of pathological state under clinical conditions. This study showed
that VAS, as a method for follow-up of pathological state, is more applicable
and efficient when applied in chronic pain evaluation.
