OBJECTIVE
To evaluate the effect of processing solution depletion on the image quality of F-speed dental X-ray film (Insight), compared with Ektaspeed Plus.
METHODS
The films were exposed with a phantom and developed in manual and automatic conditions, in fresh and progressively depleted solutions. The comparison was based on densitometric analysis and subjective appraisal.
RESULTS
The processing solution depletion presented a different behaviour depending on whether manual or automatic technique was used. The films were distinctly affected by depleted processing solutions.
CONCLUSIONS
The developer depletion was faster in automatic than manual conditions. Insight film was more resistant than Ektaspeed Plus to the effects of processing solution depletion. In the present study there was agreement between the objective and subjective appraisals.
目的
与Ektaspeed Plus胶片相比，评估冲洗液耗尽对F速牙科X线胶片（Insight）图像质量的影响。
方法
使用模体对胶片进行曝光，并在新鲜和逐渐耗尽的溶液中，分别采用手动和自动方式进行显影。通过密度分析和主观评价进行比较。
结果
冲洗液耗尽的表现因采用手动还是自动技术而有所不同。胶片明显受到耗尽的冲洗液的影响。
结论
自动显影条件下显影剂耗尽比手动条件下更快。Insight胶片比Ektaspeed Plus胶片更能抵抗冲洗液耗尽的影响。在本研究中，客观评价和主观评价结果一致。
