摘要： A periodontal probe has a probe finger extending from a handle to an L-shaped distal end which includes a tip adapted for insertion into a periodontal pocket and formed of a thermally insulative material. A temperature sensing element is mounted at the extreme end of the tip. Conductive leads extend from the sensing element, through the probe tip to the handle. In a preferred embodiment, the temperature sensor is a thermocouple or thermistor, and the tip is sealed within an epoxy outer skin. The tip tapers so that the thermal mass of the probe in the vicinity of the sensing element quickly attains the temperature of surrounding tissue while minimally perturbing that temperature. The handle may contain signal processing or temperature display units, and the probe tip preferably includes graduations for indicating probe depth. Interchangeable sensor matching circuit elements adapt sensor elements having different characteristics to a common display driver. A system includes a probe and a processor with a display which indicates periodontal site locations to prompt entry of temperature measurements and to display disease indications based on those measurements. The temperatures are processed and are compared to stored tables of temperature difference distributions, to provide site-specific tissue diagnosis.
摘要翻译： 牙周探针具有从手柄延伸到L形远端的探针，所述探针指向包括适于插入牙周袋并由绝热材料形成的尖端。 温度感测元件安装在尖端的最末端。 导电引线从感测元件延伸，通过探针尖端延伸到手柄。 在优选实施例中，温度传感器是热电偶或热敏电阻，并且尖端密封在环氧树脂外皮内。 尖端变窄，使得探测元件附近的探头的热质量快速达到周围组织的温度，同时最小程度地扰乱该温度。 手柄可以包含信号处理或温度显示单元，并且探针尖端优选地包括用于指示探针深度的刻度。 可互换传感器匹配电路元件将具有不同特性的传感器元件适用于公共显示驱动器。 系统包括探针和具有显示器的处理器，所述显示器指示牙周位置位置以促进进入温度测量并基于这些测量显示疾病指示。 处理温度并将其与存储的温差分布表进行比较，以提供位点特异性组织诊断。
