In the contemporary dental practice, alleviation of pain is the most important factor to ameliorate patient's condition and to gain one's confidence towards the skills of the operator. Such confidence aids to the ultimate success of the treatment procedures.
This study compares the pain response of a group of 10 subjects to the Wand(®) with the response to traditional syringe injections and also compares the extent of the area anesthetized.
10 subjects were selected for the study and 20 injections were given contralaterally to them, 10 with Wand(®), and rest with the traditional aspirating syringe. Each subject received 2 injections on the palate, Left side with Wand(®) (test) and Right side with Traditional syringe (control). All injections were given by the same investigator without the use of topical anesthetic spray/gel. Pain perception levels were recorded with a visual analogue scale. Also the extent of area anesthetized with a single palatal injection was assessed by probing.
The results showed injections with the syringe were more painful than injections with the Wand(®) in 2 of 10 subjects. Also the extent of the area anesthetized by both the techniques was similar except in 2 patients.
The Wand(®) results in less painful injections; however, mean ratings of pain for both the groups, were mostly below the annoying level of pain. Also, the areas covered by the anesthetic effect of both the injections were comparatively similar.
在当代牙科实践中,缓解疼痛是改善患者状况以及增强患者对操作者技术信心的最重要因素。这种信心有助于治疗程序的最终成功。
本研究比较了一组10名受试者对Wand(®)的疼痛反应与对传统注射器注射的反应,并比较了麻醉区域的范围。
选择10名受试者进行研究,在其双侧进行20次注射,10次使用Wand(®),其余使用传统抽吸注射器。每位受试者在腭部接受2次注射,左侧使用Wand(®)(测试),右侧使用传统注射器(对照)。所有注射均由同一名研究者进行,不使用局部麻醉喷雾/凝胶。用视觉模拟量表记录疼痛感知水平。此外,通过探查评估单次腭部注射麻醉的区域范围。
结果显示,在10名受试者中有2名受试者使用注射器注射比使用Wand(®)注射更疼痛。除2名患者外,两种技术麻醉的区域范围相似。
Wand(®)注射时疼痛较轻;然而,两组的平均疼痛评分大多低于令人烦恼的疼痛水平。此外,两种注射的麻醉效果覆盖的区域相对相似。
