tx- simple caries-resotoration (fillings)
pulpitis- abx and NSAIDS; root canal may be needed
high risk pop- anything that causes spit to decrease and have a dry mouth (chemo, drugs, xerostomia secondary to other stuff)

pres: C/O oral dryness, burning of mouth, difficulty eating and swallowing, tongue irritation, painful ulcerations.
tx-Salivary stimulation with sugarless hard candies
Saliva substitutes
Sialogogues: pilocarpine or cevimeline
Meds that increase salivation

18

hoarsness and dysphonia
freq seen w/ URI
inflammation of vocal fold mucosa and larynx
actue sx3 weeks

19

most common cause of laryngitis

VIRAL
can be bacterial, vocal trauma, gerd, autoimmune, environmental factors, use of asthma inhalers

20

Medical management of etiology

23

vocal nodules

Thickened areas on the vocal cord, bilaterally occurring at the junction of the anterior and middle thirds (analogous to a callus)
Usual cause: smoking, reflux, muscle tension dysphonia, vocal abuse
