Assessment of subjective intensity of pain during ultrasonic supragingival calculus removal: A comparative study.

BACKGROUND

The background of the following study is to measure the subjective intensity of pain using the verbal rating scale (VRS) during supragingival scaling in relation to mandibular anteriors, with an ultrasonic scaler, with 2 different inserts (Slimline and Focus spray)- split mouth study.

MATERIALS AND METHODS

A total of 30 subjects with a combination of 17 males and 13 females with the chronic generalized gingivitis with a minimum calculus score of 1 (CSSI - Ennever J 1961) who reported to Department of Periodontics, Yenepoya Dental College, Mangalore were chosen for the study. Ultrasonic magnetostrictive scaler unit CAVITRON BOBCAT PRO(®)- (DENTSPLY) with maximum power setting at 130A and 25kHZ frequency with 2 different inserts i.e., Slim line insert and Focus spray (DENTSPLY) were used for supragingival scaling in the study. A VRS was used to assess the subjective intensity of pain.

RESULTS

There was no statistically significant difference in pain perception when the scores were compared using Wilcoxon signed rank test. VRS rating scores with slimline inserts showed a pain intensity of 2 in 43.3%, 1 in 53.3% and 0 in 3.3%, whereas the focus spray insert showed a pain intensity of 1 in 23.3% and 0 in 76.7%. Statistical analysis showed a P = 0.251 and a z - 1.147(a).

CONCLUSIONS

The use of both Slim line insert and Focus spray inserts when used at same settings of the scaling unit, showed no statistical significant difference in the intensity of pain perceived and it showed no correlation between patient acceptance and their pain perception.
