OH! let me have a go at this one! the epithelial attachment is different to the junctional epithelium that the epithelial attachment is just the internal basal lamina layer of cells connecting to the tooth (by hemidesomes). When we probe we go towards the entire junctional epithelium and the bottom of the sulcus. the probe can penetrate through the JE and is stopped by the underlying connective tissue fibres - so i would say when we probe we disrupt the epitheliam attachment however we do not completely destroy it...
worth a shot! (prob wrong but a write answer would be great!)
i agree with nikki - the EA (internal basal lamina together with hemidesmosomes) is what attaches the JE to the tooth surface (the 'glue') - when we probe the JE - in clinical health the JE will be somewhat resistant to penetration of the probe (underlying CT fibres), however, there is still minor damage caused to the base of the sulcus - this is because to obtain a fairly 'accurate' measurement the pressure in probing needs to be enough so that it hits and slightly penetrates the base of the sulcus - disrupting it and therefore the EA.......please tell me if i'm wrong!!!! (>_<)
You guys sound right to me. While we know that the junctional epithelium is penetrated and damaged by the perio probe, I am guessing that the JE's attachment to the surface of the tooth (the epithelial attachment) is not compromised.
In other words I don't think the perio probe scrapes off the 'glue' connecting the JE to the tooth.
Ok guys .. you are correct! The Epithelial attachment is not disrupted by perio probing. The Junctional Epithelium on the other hand, can be disrupted. There is a great description of the epithelial attachment in the latest article I sent everyone. Please make sure you read it! Its puts everything into perspective.

that was meant to say 'right' answer...

As for 'why', I am guessing that the epithelial attachment is stronger than the intercellular attachment of the JE.
