hi students now we are going to examine the width of the attention driven first of all we should know the microscopic features of the gingiva in order to demarcate how much of attaching java that is present in the patient now for this yes so basically let's start with the microscopic features of the gingiva i hope you all very well uh know that this is the gingival matrix this is the papilla the capillary area the triangular area in between and this is the attached gingiva normally the marginal gingiva and the attaching java is demarcated by a freeze interval group but most of the patients this free enjoyable group is very difficult to be appreciated well now after the attack gingiva comes the alveolar mucosa this angular reposa is highly vascular this is very elastic and highly mobile as well the zone or the boundary between the arula mufosa and the attaching gyra is what we want to appreciate using the tension test now so this boundary is called as the muco gingival junction now in order to verify how much of attaching java is present we need to find where is the nippo gingival junction now what does attaching is from the nico gingival junction to the base of the sulcus or the pocketed pocket depth so if at all you are measuring the entire keratinized gingiva it is from the marginal gingiva rest of depositing driver until the nippochanjaraba junction now if you want to measure this so this is the matrix integral and this is the nuclear interval junction so it stands roughly around 5 mm okay so from this 5 and n if you actually want to calculate the width of attaching java you have to subtract the sulcus depth now how much is the sunken step in this case it is it looks around 1 mm so there is around 4 mm of the width of a titan diva this is one aspect of measuring the width of a gingiva clinically in a patient how to assess whether the width of attack gingiva is adequate or not for this we need to use something called tension test in this tension test it is very simple you just have to use the patient lower lip and move it outward and forward like this and keep on pulling the lip outward and forward direction by doing that you will be able to demarcate the nucogen diver junction very well as you see this movement you please observe if there is any movement noticed on the enjoyable margin or on the papilla if at all while you are moving the lid if there is a movement you are moving the lip in this fashion outward and forward if you observe any movement of the papilla or the material gingiva then that means the attaching java is inadequate let us see now observe whatever i am showing whether you do you really observe any movement of the papilla or the marginal ginger no not really right because there is sufficient or adequate amount of attaching gyra this attached gingiva resists highly the movement of the this attaching chamber is very tenacious adhere to the periosteum and therefore the movement can be resisted therefore the movement is not transferred to the marginal gingiva or the papilla in case in any other cases if you see there is inadequate attaching java then the movement whenever you do this tension test you can observe there is movement of the papilla and the marginal gingiva so as you move the lip then the sulcus can be opened up and this can also lead to pocket formation gingival recession and many other gingival inflammatory signs so this is very very important to assess the amount of attaching java in a patient to assess the width of attached gingiva the another technique that can be used is roll technique for roll technique you take a basically a periodontal probe and you put the probe like this in a flat direction on the alveolar mucosa and once you put the probe in the other mucosa you roll the lip like this if at all the probe comes and lands up in the marginal gingiva that means the the amount of attached gingiva is inadequate if there is no amount of width of attaching java is inadequate then once the mucosa is rolled then the probe can be tilted until the marginal gingiva or the papillary area but in this case if you see there is enough amount of gingiva attaching adequacy is present so when even when the ginger when the lip is being rolled the probe is not being pushed because it will stop the attaching java will act as a barrier and it will stop moving movement of the probe beyond this point okay so this is actually how you assess the roll technique
