Comparison of Different Pain Rating Scales in Patients With Symptomatic Teeth

Patients with symptomatic teeth who applied endodontic clinic between April 2019 and December 2019 for root canal treatment were enrolled in this study. All patients were asked to fill four different rating scales: numerical rating scale, visual analogue scale, color analogue scale and faces rating scale for their relevant tooth which is symptomatic and need of root canal treatment. The four scales were then compared statistically.

About this study

50 patients who applied endodontic clinic between April 2019 and December 2019 and had symptomatic teeth which were in need of root canal treatment were enrolled for this study. Study detail were explained to all patients and they were then kindly asked to signed a consent form. All patients diagnose, age, gender, tooth number were recorded. Patients were then asked to fill four different pain rating scale in an electronic pain rating scale program. Numerical rating scale (NRS) was a scale between "0" and "10", with "0" indicating no pain while "10" indicating worst pain possible. Visual analogue scale (VAS) was a straight line of 10 cm with one end of the line indicated no pain whilst the other end indicated worst pain possible. Color analogue scale (CAS) was the same length of straight line as in VAS with a color change towards to worst pain possible end. Faces rating scale (FRS) consisted of six different faces indicating the level of pain with the first face indicated no pain while the last face indicated worst pain possible. After the patients marked their pain intensity levels in all four scales the results were statistically analyzed to compared the accuracy of four scales with VAS being the golden standard.

Treatment and study plan

numerical rating scale

Diagnostic Test

patients were asked to marked their pain intensity level on numerical rating scale between 0 and 10 and the result was recorded as pain intensity level.

Other names: NRS

Visual Analogue Scale

Other

Patients were asked to marked their pain intensity level on visual analogue scale, a straight line with one end indicating "no pain" and the other end indicating "worst pain possible". Then the distance between no pain end and patients' mark was measured and recorded as pain intensity level.

Other names: VAS

color analogue scale

Other

Patients were asked to marked their pain intensity level on color analogue scale, a straight line with one end indicating "no pain" and the other end indicating "worst pain possible"and color change towards to "worst pain possible" end. Then the distance between no pain end and patients' mark was measured and recorded as pain intensity level.

Other names: CAS

faces rating scale

Other

Patients were asked marked their pain on a faces rating scale which consisted of six different faces representing different levels of pain intensity with the first face indicating "no pain" whilst last face indicating "worst pain possible". The result was recorded as pain intensity level.

Other names: FRS

Primary outcomes

  1. numerical rating scale

    Time frame: through study completion, an average of 1 year

    pain intesity level of patients were recorded on a scale from 0 (no pain) to 10 (worst pain posbile)

  2. visual analogue scale

    Time frame: through study completion, an average of 1 year

    Patients were asked to mark their pain intesity level on a 10 cm line with one end indicating "no pain" and the other end "worst pain possible". The distance between "no pain" and the mark indicates the pain intesity level.

  3. color analogue scale

    Time frame: through study completion, an average of 1 year

    Patients were asked to mark their pain intesity level on a 10 cm color changing line with one end indicating "no pain" and the other end "worst pain possible". The distance between "no pain" and the mark indicates the pain intesity level.

  4. faces rating scale

    Time frame: through study completion, an average of 1 year

    faces rating scale consists of 6 faces with the first face indicating "no pain" and the last face indicating "worst pain possbile"

  5. comparison of four rating scales

    Time frame: through study completion, an average of 1 year

    all four pain rating scales (numerical rating scale, visual analogue scale, color analogue scale, faces rating scale) were compared to analyze correlation.
