A new electric pulp-testing system, the Testark, was developed in order to assess the potential of a different way of testing pulp sensitivity, thus making this electric pulp test more dependable than the conventional electric pulp-testing method. A study was conducted to evaluate the potential of the Testark system in comparison with a commercially available pulp tester. This pilot study consisted of application of three different desensitizing agents (sodium fluoride, test product. 'A', and test product 'B') to the cervical areas of hypersensitive teeth. The results were recorded with both the Testark and the conventional pulp tester simultaneously, and the sodium fluoride and test product 'B' proved to yield a beneficial effect by desensitizing the teeth after a single application. The level of desensitization with these agents was higher than the level obtained with the test product 'A' paste, which was utilized daily for 14 days. The results obtained with the conventional pulp tester differed by way of interpretation from those obtained with the Testark system. The Testark system proved to be easy to use and highly accurate in the data readings because of its high resolution. The Testark systemwas found to be more dependable than the commerical pulp tester, since it reduced the subjective errors which are inevitable when a commerical pulp tester is used. The Testark system is being developed further, and more studies are being conducted at the present time, in order to assess the full potential of the instrument.
一种新型的牙髓电测试系统——Testark被研发出来，目的是评估一种不同的牙髓敏感度测试方法的潜力，从而使这种牙髓电测试比传统的牙髓电测试方法更可靠。开展了一项研究，以评估Testark系统与一种市售牙髓测试仪相比的潜力。这项初步研究包括将三种不同的脱敏剂（氟化钠、测试产品“A”和测试产品“B”）应用于过敏牙齿的颈部区域。同时用Testark和传统牙髓测试仪记录结果，结果表明，氟化钠和测试产品“B”在单次应用后通过使牙齿脱敏产生了有益效果。这些药剂的脱敏程度高于测试产品“A”糊剂，测试产品“A”糊剂连续14天每日使用。传统牙髓测试仪获得的结果在解释方式上与Testark系统获得的结果不同。Testark系统因其高分辨率而被证明易于使用且数据读数高度准确。发现Testark系统比市售牙髓测试仪更可靠，因为它减少了使用市售牙髓测试仪时不可避免的主观误差。Testark系统正在进一步研发，目前正在进行更多研究，以评估该仪器的全部潜力。
