Question | Answer |
what depends on the success/failure of treatment | thorough debridement, patient compliance, disease severity, host immune response |
4 methods to reduce bioburden | brushing, interproximal cleaning chemotherapeutics using exploratory stroke scaling, polishing |
cavitation | inward collapsing of bubbles shock waves disrupt bacterial cell wall |
microstreaming | hydrodynamic stress is produced close to oscillating object swirling acoustic turbulence disrupts plaque biofilm |
what are the two forms of plaque when it is undisturbed and migrates subgingivally | adherent (Gram positive, rods and cocci) nonadherent and loose (gram positive, gram negative) |
what happens with nonadherent plaque | enzymes released-->antigens-->LPS damaged-->immune response if defense mechanism fails-->inflammatory mediators (cytokines, interleukins, enzymes) |
what happens to the tissue are debridement | debridement-->wound-->clot between collagen fibers and soft tissue |
what is the epithelium proliferation per day | 0.5mm/day |
what do fibroblasts do | create collagen |
what are the healing rates for epithelium, CT, bone | epi. 5-14days CT. 21-28 days bone. 4-6 weeks |
sonic power instrument characteristics | air turbine unit, colled by h2o 2500-7000 cycles/sec ellipitical or linear |
ultrasonic magnetostrictive power instrument characteristics | nickel alloy power setting: amplitude of vibration (length of stroke) increase power=longer, powerful stroke frequency: # of tip cycles/sec elliptical 8000-45000 |
frequency | how many vibrations per second (tuning=frequency) |
stroke/amplitude | how far tip moves |
piezoelectric power instrument | ceramic crystals linear lateral surface more active than flat front or back can also hold chemotherapeutics agents 29000-50000 |
universal tip | mod.-heavy supragingival, operated med.-high settings |
modified tip | right, left inserts, slim tips, access deeper pockets, operate lower setting, subgingival |
furcation tip (0.52) | ball on end of tip |
diamond tip | remove tenacious calculus |
carbon composite tip | used for implants |
medical precautions/contraindications | unsheilded pacemakers, hepatitis, TB, HIV, immunosuppression, diabetes, organ transplants, asthma, emyphysema, cystic fibrosis, pulmonary diseases, implants, non metallic restorations, exposed dentin/demineralization, children |
indications | remove calculus and stain, reduce bacterial bioburden (furcations, period. pockets), remove overhangs and excess cememnt |
how do you clean the ultrasonic tips | sterilization autoclave only carbon steel can't be put into ultrasonic solution |
