Full periodontal assessment  Probing depth = Light probing force of 25g 0.48mm- distance from ball end gingival margin to the bottom of periodontal pocket. BPE is a screening 0.5mm ball endS 3.5-5.5mm 1-15mm markings tool only!

Probe cannot enter Probe unable to completely furcation area. pass through furcation. Not visible on radiographs. Nabers probe Visible on radiographs. is used to measure furcations Grade 3 Grade 4 A Lower molars - probe passes completely through furcation. Same as class 3. Entrance is visible clinically Upper molars - probe passes due to bone loss and recession. through, touches palatal root. Visible on radiographs. Lower molar visible on radiographs but not upper molars due to palatal root. Mobility - Miller 1950 Grade 0 - normal mobility 0.1-0.2mm in horizontal direction. Grade 1 - up to 1mm, slight mobility, horizontal direction. Grade 2 - greater than 1mm, moderate mobility, horizontal direction. Grade 3 - greater than 1mm, severe mobility, horizontal and vertical direction. Plaque Index 6 point plaque/bleeding score Be clear & state when crossing midline 4 point plaque/bleeding score Changes colour of Tablets, liquid or pre- Equipment: plaque biofilm, to loaded pellets -- provide contrast PPE against tooth. Warning/consent from patient Disclosing solution Cotton wool/pledget Usually vegetable dye Disclosing Eye protection agent Scribe - Removal mechanism Aspiration Benefits: Motivation and education tool for patients Easy to remove Visualise Always use Non-allergenic Self monitoring tool for patient vaseline to No flavouring/sugar Direction for OH advice ensure lips do Easy to use and remove not stained Plaque & bleeding index calculation: 1. Strike off missing teeth 2. Calculate total number of surfaces (teeth number X 4 OR 6) 3. Mark and add up teeth with plaque/ Disclosing agents can be single toned, bleeding present. two or three toned: 4. Divide teeth with plaque/bleeding present Pink — plaque 24 hours old 5. Multiply by 100 to get %. Aqua — very acidic & aggressive plaque Bleeding Index WHO probe Immediate bleeding —.As soon as you insert probe into pocket/sulcus. used to take bleeding index Delayed bleeding — Insert probe at base of pocket, bleeding happens few seconds later. Indication of periodontal disease progressing and early signs of gingivitis. Calculated and charted the same as plaque index, 4 or 6 point charts. 30% bleeding considered clinical considered considered gingival health localised generalised
