To assess subjective intensities of pain during supragingival calculus removal employing ultrasonic scaler tips of two different shapes.
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.
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]) (p<0.05). 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 (p<0.05).
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 patient's compliance during dental treatment with oscillating instruments.
评估使用两种不同形状的超声洁治器尖端去除龈上牙石时的主观疼痛强度。
采用分口设计，对20例患者使用压电超声设备（Sirosonic L）以及代表传统形状（器械编号3）和细长型（牙周专业系列器械SI - 11）的两种不同洁治器尖端进行治疗。在去除牙石过程中，每隔0.5秒采用多模式强度比较记录疼痛情况。此外，在治疗结束后立即使用视觉模拟量表进行评估。记录治疗时间以评估牙石去除效率。
治疗期间的疼痛评估显示，细长型洁治器尖端（疼痛评分中位数：1.4 [U]，最大值：3.5 [U]，最小值：0 [U]）引起的疼痛比传统器械（疼痛评分中位数：7.8 [U]，最大值：14.7 [U]，最小值：0 [U]）少（p<0.05）。这些结果可通过视觉模拟量表得到证实。使用细长型尖端治疗比使用传统尖端治疗所需时间明显更长（p<0.05）。
使用细长型超声洁治器尖端去除龈上牙石，与传统超声设备相比可减轻疼痛感。因此，在使用振荡器械进行牙科治疗时，有可能提高患者的依从性。
