Subjective intensity of pain during ultrasonic supragingival calculus removal
: Blackwell Synergy
Objective: To assess subjective intensities of pain during supragingival calculus
removal employing ultrasonic scaler tips of two different shapes.
Material and Methods: Twenty patients were treated using a piezoelectric ultrasonic
device (Sirosonic L) and two different scaler tips representing a conventional
(Instrument No. 3) and a slim-line style (Perio Pro Line Instrument SI-11) in a
split-mouth design. Pain was recorded during calculus removal at intervals of 0.5 s
employing an inter-modal intensity comparison. Additionally, a visual analogue scale
was used for evaluation directly after the treatment procedure. Treatment time was
recorded to assess the efficiency of calculus removal.
Results: Pain assessment during treatment showed that the slim-line scaler tip
(median pain score: 1.4 [U], maximum: 3.5 [U], minimum: 0 [U]) caused less pain
than the conventional device (median pain score: 7.8 [U], maximum: 14.7 [U],
minimum: 0 [U]) (po0.05). These results could be confirmed by the visual analogue
scale. Treatment with the slim-line tip took significantly longer than treatment with the
conventional tip (po0.05).
Conclusions: Using slim-line-styled ultrasonic scaler tips for supragingival calculus
removal, painful sensations can be reduced compared with conventional ultrasonic
devices. Thus, it might be possible to increase the patientÃ¢â‚¬â„¢s compliance during dental
treatment with oscillating instruments.
