chapter 27 (supragingival and subgingival irrigation)
UPDATED ACTUAL Questions and CORRECT Answers
Power-Driven irrigation device cleans teeth by gently - pulsating water
delivering either: or
- stream of compressed air
Irrigation device uses pulsating water around and between teeth above gingival margin and into gingival sulcus or
periodontal pocket
Irrigation device uses a stream of compressed air interspersed with micro-droplets of water around and between teeth above gingival
margin and into gingival sulcus or periodontal pocket
Water jet is also known as - water flosser
- water irrigator
- home irrigator
Pulsating fluid uses alternating compression and decompression phase to displace biofilm, bacteria, and debris
Hydrokinetic activity creates two zones of fluid movement
Two zones of fluid movement includes - impact zone
- flushing zone
Impact zone is an area of initial fluid contact to portion of tooth near gingival margin
Flushing zone is the depth of fluid penetration within subgingival sulcus or pocket
Hydrokinetic fluid movement results in movement of fluid into subgingival and interdental areas
Fluid penetration has the greatest potential for reaching deeper into sulcus or pocket compared to other types of conventional oral
hygiene aids
Power-driven air floss emits microburst of high velocity compressed air interspersed with microdroplets of liquid
Power driven air floss creates shear stress to loosen plaque biofilm deposits
Removal of biofilm when using power driven irrigation at when used with manual toothbrushing, removes more biofilm than conventional
home: brushing and flossing
Benefits of home power driven irrigation - removal of biofilm
- reduction in bleeding
Reduction in bleeding when using power driven irrigation daily irrigation significantly reduced bleeding and significantly better than rinsing
at home: with 0.12% chlorhexidine at reducing marginal bleeding and bleeding on probing
