The purpose of this study was to compare a single-use, disposable, presterilized light activation probe with an equivalent autoclavable probe. Light output, heat generation, and depth of cure were investigated.
Ten disposable and two reusable probe tips were tested. Three maximum light output readings for each tip were recorded with a radiometer. Heat generation at the probe tip was recorded, at 30-second intervals over a five-minute period, with a thermocouple probe placed under a 3-mm-thick glass slide. After light-activated "compomer" was placed in a sectional two-piece stainless steel mold and cured, depth of cure was evaluated using the scrape technique.
With respect to light output and depth of cure, there were no statistically significant differences between probe types, but the disposable probe generated significantly less heat.
The disposable probe performed clinically as well as an autoclavable counterpart with respect to light output, heat generation, and depth of cure.
本研究旨在比较一次性使用、预消毒的光固化探头与同等可高压灭菌探头。对光输出、产热及固化深度进行了研究。
测试了10个一次性探头尖端和2个可重复使用探头尖端。用辐射计记录每个尖端的三次最大光输出读数。将热电偶探头置于3毫米厚的载玻片下，在5分钟内每隔30秒记录一次探头尖端的产热情况。在光固化“复合体”置于分段两件式不锈钢模具中固化后，采用刮擦技术评估固化深度。
在光输出和固化深度方面，不同类型探头之间无统计学显著差异，但一次性探头产热显著较少。
在光输出、产热及固化深度方面，一次性探头在临床上与可高压灭菌探头表现相当。
