Q

Why is there bone loss

A

there is bacteria on the teeth
the white blood cells want to get away from this bacteria but they can’t
so the way it responds is to move away by resorbing bone and with bone loss comes soft tissue loss

Q

How can diabetes modify periodontal disease

A

diabetes increases inflammation in the periodontal tissues

hyperglycemia can also result in the activation of pathways that increase inflammation

extrinsic staining
calculus build up
transient taste disturbance
effect son oral mucosa

38
Q

What are the key points to behavior change

A

pick good words to use, better than a full lecture
offer assistance and seek permission to give knowledge - involve the patient. the natural response to force is resistance

on the best ways to perform effective plaque removal

42
Q

What should you practice?
