Clinical session 2 Flashcards
What can be used for interdental cleaning?
- dental floss
- superfloss
- flosette
- interdental brushes
- water flosser
what manual toothbrush technique is recommended
modified bass technique
what are single tufted brushes good for
cleaning around implants, orthodontic appliances, crown and bridgework, difficult to reach areas
why is chlorhexidine mouthrinse not recommended for routine everyday use
- causes extrinsic tooth staining
- calculus build up
- transient taste disturbance
what BPE codes require a 6 point pocket chart
3,4 and *
What can be recorded using a 6 point pocket chart
- probing depth
- bleeding on probing
- gingival margin
- loss of attachment
- mobility
- furcation involvement
what is the minimum requirement for a six point pocket chart
to record all sites ≥4mm probing depth and bleeding on probing
which periodontal probe do you use to do a 6 point pocket chart
PCP 12 probe
What measurements do I record on a 6PPC
- Probing depth (base of gingival crevice to gingival margin)
- Recession (gingival margin the CEJ)
- Loss of attachment (probing depth + recession)
how do you calculate loss of attachment
probing depth + recession
how is furcation graded
grade 1 = initial furcation involvement. The furcation opening can be felt on probing but the involvement is less than 1/3 of the tooth width
grade 2 = partial furcation involvement. Loss of support exceeds 1/3 or the tooth width but doesn’t include the total width of the furcation
grade 3 = through and through involvement. The probe can pass through the entire furcation
how is mobility graded
grade 0 - ‘physiological’ mobility measured at the crown level. The tooth is mobile within the alveolus to about 0.1-0.2mm in a horizontal direction
grade 1 - increased mobility of the crown of the tooth to at most 1mm in a horizontal direction
grade 2 - visually increased mobility of the crown of the tooth exceeding 1mm in a horizontal direction
grade 3 - severe mobility of the crown of the tooth in both horizontal and vertical directions impinging on the function of the tooth.
what would the loss of attachment be if the probing depth = 8mm and the recession was -3mm?
5mm
what would the loss of attachment be if the probing depth = 4mm and the recession was 2mm?
6mm
what are the 6 sites around the teeth you place the probe in
- disto-buccal
- mid- buccal
- mesio-buccal
- disto- palatal
- mid-palatal
- mesio-palatal
(n. b. lingual in lower)
what is correct placement of the probe in the pocket
- probe tip gently placed into gingival crevice until it reaches the base
- position as parallel as possible to the tooth surface (parallelism)
- the side of the probe tip should be kept in contact with the tooth surface (adaptation)
- probe is “walked” around the gingival margin of the tooth
what probe is used for furcation involvement
nabers probes
you carry out a 6PPC and record the following measurements for the mesio-buccal site of tooth 21:
bleeding on probing = 1
gingival margin = -2
probing depth = 7
mobility = grade 1
calculate the loss of attachment in millimeters for the mesio-buccal site of tooth 21
5mm
how much pressure should you apply when “walking” the gingiva with the probe in a 6PPC
25mg pressure
need to press a bit cause need to get through any granulous tissue but don’t want to create new pockets
