To compare the finger pressure applied by dentists during cementation and to examine the effect of gender and time of day on finger pressure.
Fifteen dentists (9 males, 6 females) formed a study group and 10 master dies in premolar shape and Turcom Cera all-ceramic crowns were prepared to measure the maximum finger pressure applied by dentists during cementation. The dentists performed a total of 300 cementation processes. One-way analysis of variance and independent t tests were used to evaluate the results.
A statistically significant difference was found in the amount of pressure applied during cementation (P<.005). However, there was no significant difference for time of day or gender according to one-way analysis of variance.
Our results show that finger pressure varies by dentist. For this reason, the optimum pressure should be determined exactly. Special equipment or an apparatus could be developed to apply that pressure.
比较牙医在粘结过程中施加的手指压力，并研究性别和一天中的时间对手指压力的影响。
15名牙医（9名男性，6名女性）组成一个研究组，制备了10个前磨牙形状的 master 代型和 Turcom Cera 全瓷冠，以测量牙医在粘结过程中施加的最大手指压力。牙医总共进行了300次粘结过程。采用单因素方差分析和独立t检验来评估结果。
在粘结过程中施加的压力量存在统计学显著差异（P<0.005）。然而，根据单因素方差分析，一天中的时间或性别没有显著差异。
我们的结果表明，手指压力因牙医而异。因此，应准确确定最佳压力。可以开发特殊设备或器械来施加该压力。
