Answer 8

• painful, tender when eating, may feel mobile
• attached gingiva usually close to apex
• deep PPD
• negative sensibility tests

Question 9

step one perio treatment for BPE 4

Answer 9

• radiographic assessment
• full mouth 6PPC
• MPBS
• diagnostic statement
• explain disease, treatments and risk factors
• tailored OHI
• risk factor modification
• supragingival PMPR

Question 10

why was composite chosen for 15do restoration

Answer 10

moisture control was achieved using dental dam
avoid destructive prep to create self -retentive box

Question 11

why do smokers gums bleed less

Answer 11

nicotine causes vasoconstriction resulting in less blood flow to gingivae

Question 12

why was the 14 retained root extracted

Answer 12

unrestorable
infection risk
inadequate OH for overdenture

Question 13

criteria for engaging perio patient

Answer 13

> =50% improvement in plaque and bleeding
plaque levels <=20% and bleeding levels <=30%
patient met personal targets

Answer 17

easier to add to
(abutment teeth likley to be lost in relatively near future)

Question 18
