|---|---|
 POWERED SCALING | good when treating >3mm pockets. effective for furcations. Ultrasonics=Magnestostrictive (cavitron), piezoelectric, Sonics. |
| CAVITATION | property assoc w ultrasonic that causes water to atomize as passes over vibrations of moving tip creating air cavities that collapse an explode causing cell disruption within perio pocket |
| ULTRASONIC | hi freq current and compressed air up to 18-50,000 cps, with cooling water spray. Magneto=18-45000 Peizo=25-50000 cps |
| MAGNETOSTRICTIVE | eliptical motion. side, back or front of tip. more power=heavy deposit, may decrease pt confort. PT comfort=power, tuning, tip, tecnique. working tip=insert. stack of nickel alloy, ferrour rod has water around. 25k and 30k(quieter). smaller/thinner pockets, color coding, lightening, swivel. |
| WORKING TIP | magnet=insert |
| PIEZO | line movement, no heat in handpiece--ceramic and quartz. vibratory moion in tip. movement creates heat. ONLY LATERAL surface--sound alerts. Working tip=screw on. used in Endo, surgery, restoration, perio. tips not interchangeanble between brands |
| SONIC SCALER | same as ultrasonic, powered by air turbine, attach like hand piece, 3000-8000cps, linnear or eliptical, al surfaces of tip. changeable tips, |
| TIPS | factors: access, location, conition of tissue, pocket depth, root morphology |
| UNIVERSAL TIPS | designed by size for sub debridement and supra thicker/wider. |
| MODIFIED TIPS | perio/sub g. 1980, thinned and reshaped. perio inserts-low-med power, straight, area specific furcation: .8mm or .5mm ball end. reduces gouging, straight, right, left. diamond tip: megnet=remove tenacious calc, soft tissue debride, remove ag overhand, peizo: low power |
| HEALTH | pacemakers: not affected by peizo. communicable disease respiratory diseases: astham, copd, emphysema, cystic fibrosis gagging/dysphagia (swallow). contraindicated: titantium implants, restoratives, sensativity, demineralization, |
| Chlorhexidine | 1 min for .12%. or 40 sec w listerine |
| POWER TIP | tip, concave side, convex (back side), lateral |
