[Music] so if someone has a healthy mouth there are three categories that um we can say under periodontal health they could have periodontal health or a healthy amount on an intact periodontium on a mouth that has no bone loss they could have periodontal health on a reduced periodontium in a non-periodontitis patient or they could have periodontal health on a reduced periodontism in a successfully treated stable periodontitis patient a month away well let's look at all of these conditions and understand what they what they all mean so periodontal health on an intact periodontium this is the normal one that we would see if someone's mouth is healthy like this person here this person has a healthy mouth coral pink we see stippling the gums are nice and snug against the uh the teeth and there's no redness so this person has a healthy mouth and when we look at their radiograph you can see that the bone level is is perfectly normal remember the bone should be just two millimeters below the cej and so here is our cej right here and it's just two millimeters below and the bones are exact so because the bones are intact um this is an example of someone who is completely healthy early on total health on an intact periodontism on a periodontium that is intact where there's no recession and there's no bone loss now sometimes we can see periodontal health so gums that look healthy and again you might see recession and you might say oh i don't think this is healthy but if i were to probe in this area i wouldn't see much bleeding um and it looks fairly pink so here's an example of a healthy or somewhat healthy mouth but it is a reach it is on a reduced periodontium see the recession the recession is making it a reduced periodontium and it is on a non-periodontitis patient it is on a patient or a client who does not have bone loss so they don't have significant bone loss over here the reason why we see this recession is because perhaps this client was brushing excessively when they were probably using or he or she was probably using a hard toothbrush and scrubbing like crazy and it was causing these recession so healthy mouth generally speaking it is a healthy mouth but it is a healthy mouth on a reduced periodontium in a non-period anti-dissipation in a patient who does not have periodontitis food is not a bone loss and this patient has a reduced periodontium it does have recession and the reason why it has recession is because of excessive brushing but this patient does not have periodontitis this person is not a periodontal client and the reason is because they don't have significant bone loss they don't have bone loss here we see is a person who has healthy gums well the gums are pretty healthy there is no bleeding if i were to probe there's no bleeding it looks pretty nice and pink so this person has healthy gums known as periodontal health but it is on a reduced periodontium and why is it on a reduced periodontium we see recession right the gum should be over here so the gum should be over here and it has receded it has gone down and this person is a periodontal patient we see significant bone loss right the bone levels should be over here and we see the bone has gone down so this is someone who had periodontitis but now it's stable so now the bone level is right over here and as we're monitoring this patient the bone level is not worsening it's staying the same so when we have a patient who is who has healthy gums who had bone loss in the past but it's successfully treated they're doing brushing their floss and they're coming to see the dentist or hygienist regularly and maintaining their oral health this is a person who we would classify as someone who has periodontal health on a reduced periodontism which is pre-adoption because they do have some recession there uh the gums have gone down but this person has successfully treated stable periodontitis that means that yes they had bone loss in the past as we see here the bone level has gone down but it is stable the bone level is not worsening over time so this person is considered this statement or this category is what we would call this client
