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.
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.
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).
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.
以下研究的背景是，在使用超声洁牙机对上颌前牙进行龈上洁治时，使用语言评定量表（VRS）测量疼痛的主观强度，该超声洁牙机配有2种不同的工作尖（Slimline和Focus spray）——采用双盲法研究。
共有30名受试者入选本研究，其中男性17名，女性13名，均患有慢性广泛性牙龈炎，牙结石评分最低为1分（CSSI - Ennever J 1961），这些受试者来自芒格洛尔耶内波亚牙科学院牙周病科。研究中使用超声磁致伸缩洁牙机CAVITRON BOBCAT PRO(®)-（登士柏公司），最大功率设置为130A，频率为25kHz，配有2种不同的工作尖，即Slimline工作尖和Focus spray工作尖（登士柏公司）进行龈上洁治。使用VRS评估疼痛的主观强度。
使用Wilcoxon符号秩检验比较得分时，疼痛感知方面无统计学显著差异。使用Slimline工作尖时，VRS评分显示疼痛强度为2分的占43.3%，为1分的占53.3%，为0分的占3.3%；而使用Focus spray工作尖时，疼痛强度为1分的占23.3%，为0分的占76.7%。统计分析显示P = 0.251，z = - 1.147（a）。
在洁治设备相同设置下使用Slimline工作尖和Focus spray工作尖时，所感知的疼痛强度无统计学显著差异，且患者接受度与疼痛感知之间无相关性。
