At cocktail parties,after a Mutual Fund manager introduces himself,and if everybody just nods and resumes discussions on the weather or soccer game or should one of them seek dentist to talk about plaque,then the stock market is sound.
如果把这里的should去掉,在表达效果上有什么不同,
不好意思，问题描述的不太好，我想问的是，把这部分修改为陈述语气，在表达效果上有什么不同（个人感觉这里的虚拟假设跟前半部分的假设没什么区别）

should + 代词,是虚拟语气.
不可把should去掉,语法会有误（虽然在非正式表达时你把should去掉,别人也会懂你句子要表达的意思）.
还有疑问欢迎追问.

不好意思,回答描述的不太好,我想答的是,把这部分修改为陈述语气,（在 不是 非正式 表达f非得较真的前提下）在表达效果上会有本质上的不同（这里的虚拟假设跟前半部分的假设不是并列关系是递进关系）.
if everybody just ...or should one of them...
意为
如果大家都...,（而且）如果其中任何一个人...

should这里应该是虚拟语气的标志，该句子和if everybody just nods and resumes discussions on the weather or soccer game 是并列的。表示一种假设
补充回答：
如果去掉should，句子前面不变，但后面就会缺少虚拟语气，因为should前面是or，不是and，虽然表达意思是一样，但是这是两个单独的句子...

At cocktail parties, after a Mutual Fund manager introduces himself, and if everybody just nods and resumes discussions on the weather or soccer game or should one of them seek the dentist to talk about plaque, then the stock market is sound.
如果把这里的should去掉，在表达效果上有什么不同，谢谢.
答：先进行句法分析。
主句中最后：then the stock market is sound.
at cocktail parties是地点状语。after .... himself 是是时间状语，and 后面是条件状语。
总的句子结构是：在XX场合，在XX时间，在某种条件下， 主句。
重点分析在这个if从句。 if everybody just nods and resumes discussions on the weather or soccer game or should one of them seek the dentist to talk about plaque
and 后面的这个条件，不是一个简单的句子，是由or并列的两个条件句：
条件1. if everybody just nods and resumes discussions on the weather or soccer game
其中主语是everbody, 谓语是一个复合谓语，由and并列：谓1. nods, 谓2=resumes discussions on the weather or soccer game
条件2. should one of them seek the dentist to talk about plaque= if one of them should seek the dentist to talk about plaque
这是虚拟条件句通过倒装（将情态助动词should提到句首）从而省略了if
楼主在想，能不能一个if后面是一个并列句呢？If A dose B and/ or C does D 呢？
完全可以。
是的，should可以去掉，但是，一方面是虚拟语气不存在了（原来认为后一种情况出现的概率很少，纯假设），主要是，后一个句子主谓不一致了，要将seek改为seeks才对！
这才是should不能简单去掉的根本原因！

注：dentist 前应有一个冠词。
