跟喝油無關，隻是對你對這幾篇文章的結論有存疑

我沒有看過原文，不過大概瀏覽文章摘要，作者宣稱結果有統計學上的顯著差異。

我不覺得這點樣本足夠，也不知道這樣的研究設計是否合理，隻是，您的結論“結論都是2組沒有顯著差異。所以認為油跟消毒劑，在清潔口腔的功能上，作用等同”是如何得出的？這個是您自己分析實驗數據計算結果，還是有其它實驗支持您的論點？

RESULTS:

The comparisons of the pre and post therapy values of plaque and modified gingival index score showed a statistically significant difference (P = 0.005 and 0.007, respectively) in group I and II. There was a definite reduction in the ORG 1, ORG 2, scores and BANA test score in both groups I and II.

 

RESULTS:

There was a statistically significant reduction of the pre- and post-values of the plaque and modified gingival index scores in both the study and control groups (P < 0.001 in both). There was a considerable reduction in the total colony count of aerobic microorganisms present in both the groups.

 

There was a reduction in the S. mutans count in the plaque and saliva samples of both the study and the control groups. The reduction in the S. mutans count in the plaque of the study group was statistically significant after 1 and 2 weeks (P=0.01 and P=0.008, respectively); the control group showed significant reduction at all the four time points (P=0.01, P=0.04, P=0.005, and P=0.005, respectively, at 24 h, 48 h, 1 week, and 2 weeks). In the saliva samples, significant reduction in S. mutans count was seen in the control group at 48 h, 1 week, and 2 weeks (P=0.02, P=0.02, P=0.008, respectively).
