Q

What is the classic oral sign of Paget’s Ds?

A

Expansion of the Maxilla with pt complaint denture no longer fits

21
Q

In what ways are Diabetes pts aftected by dentures?

A
  • Excessive Ridge Resportion with lowered VDO causing Angular Cheilitis and the flange becomes pushed into the vestibule causing Epulis Fissuratum
  • More susceptible to Candida
22
Q

Where does Nicotine Stomatitis occur?

A
  • Unexpected Soft Palate
  • Denture protected the hard palate from the heat of the smoke and shunted it posteriorly
23
Q

What types of diseases are aggravated by ill-fitting dentures and improved by well fitting dentures?
