characterization of pain associated with dental hypersensitivity - ✔✔short, sharp pain
3 types of stimuli for dental hypersens - ✔✔1. thermal
2. mechanical
3. chemical
hypersensitive dentin characteristics - ✔✔1. dentin tubes open
2. large and numerous tubules
3. thin, poor calcified or breach smear layer
causes of gingival recession are defined by research? - ✔✔NO
multifactor- caused by one or more factors usually
causes of recession - ✔✔1. age
2. tooth type
3. plaque
4. trauma from brushing
**** plaque most common****
relationship with recession and age - ✔✔- increases with age
- almost, or all older adults have recession
- cumulative effect and longer presents of etiology factors
*** root caries common for older ppl***
most common area for localized recession - ✔✔mand anterior teeth
most common generalized area of recession - ✔✔buccal cervical regions
toothbrushing and recession - ✔✔traumatic toothbrushing and/or injury from abrasive
toothpaste.
technique, frequency, duration
aka "scrubbing"
no evidenve between electric and manual
