OK.. so im gonna be brave and try and answer this first-even though im not really sure.. but.I think that biofilm is NOT a risk factor for chronic perio. and this is because, as with caries periodontal disease is quite multifactorial, and risk factors relate more to things that decrease the hosts resistance to disease, such as stress, smoking etc and so as biofilm does not do this, then i believe biofilm is not a risk factor, also everyone has biofilm, but not everyone has perio-and this is because other risk factors are involved? ? .
the only reason i thought it might be was due to biofilm holding bacteria that may be associated with perio-however i dont think that is right.. ???????? Hope this is right..
I'm gonna have to agree with Nicole on this one and say no.
Biofilm on its own will not cause perio, risk factors such as diabetes, smoking, or even stress are required to decrease the host's resistance and modify the host's responses.
I remember Dr. Hirsch saying something like "severe perio destruction can occur regardless of people's oral hygiene practices or the amount of plaque/calculus present."
Ok guys.. I like your thinking.. If it were to be considered as a risk factor.. why do you think it might?? Think this one through and have a good look in your modules.. and get back to me.
If it were a risk factor I suppose it would be because biofilm formation causes gingivitis, which can then lead onto perio if other risk factors are present. Therefore, if a person has a large build-up of biofilm then they are at risk of developing perio if they also have diabetes or are a heavy smoker.
Or some may have a genetic disposition to the development of periodontal disease... so then would biofilm be a risk factor or a causative factor??? Hint: Check in your perio module to confirm.
OK so i have been thinking about this one.. and i read over the modules today.. wellsome of them :P AND i am thinking.. Thatwhile biofilm is not a risk factor, it still needs to be present for periodontitis to occur. That is.risk factors such as smoking,stress etc will all influence the actual mechanisms that cuase periodontitis, which from what i can gather from the notes, involves biofilm.. SOOO... If a person had a genetic predisposition to periodontitis, then it is likely that biofilm would be the causative factor for this?? Ithink.. MAYBE!! i hope that makes sense coz in my head it does.. :D
Nicole, I think I know what you're getting at. I've read through Module 2 and 3 and it hasn't really said anything specific about genetic predispositions (still need to read 4 and 5). Basically, although biofilm may not be a risk factor, it NEEDS to be present for the destruction of the periodontal tissues to begin. Therefore, it is a causative factor??
I agree! Dr Hirsh, has stated that you need plaque to get gingivitus which can subsequently lead to periodontal disease, but plaque (biolfilm)is only a precursur 'the right mix of risk factors for that person must also be present to get periodontal diseaase.'
Hey.. yea i think we are all on the right trackwith this and we getit.. me n tim spoke about the section( i think in orange book) about neccessary and sufficient factors..So biofilm is neccessary-but not sufficient to cause perio. This really helped to clarify it in my head good hustle team :D

I concur Neeeeeeeecole and Timmy
Tim on page 1 of Module 3 session 1 (Risk factors and human disease) he does state what you said so you are totally right :)
The cause and effect relationship lies between plaque and chronic gingivitis not periodontitis
For perio common risk factors are on page 9 of module 3:
Psychosocial factors/stress
Systemic disease (e.g. uncontrolled diabetes)
Smoking
PMN (Polymorphs) function
Genetic
Bacteria
there are a lot more in that section :)
hope this kinda helps
Hey well if biofilm was a problem with chronic perio Im sure Dr Hirsch would be brushing his teeth more than once a day as he stated he does!
lol at Munner's comment, that's what I'll remember when the exam comes along and this question pops up

I meant 'predisposition' not disposition...
