ULTRASOUND SCALER
Ultrasonic scalers are wont to take away calculus speedily from the tooth surface. The scaling tip vibrates within the supersonic vary of 20-45 kilocycle (i.e. 20,000 to 45,000 times per second), with AN optimum frequency between eighteen kilocycles and 32kHz.
.The sonic pulse counter operates at a coffee frequency of regarding three,000 to 8,000 cycles/second (which is what number times the tip comes up-to-date with the tooth). The sonic pulse counter is air-driven, and also the tip moves in AN elliptical motion. The supersonic handpiece utilizes either magnetostrictive or piezo-electric technology. Magnetostrictive inserts operate at twenty,000 to 45,000 cycles/second and, just like the sonic pulse counter, have AN elliptical motion. A low-tension magnetic signal causes tip movement. Piezo-electric technology operates at twenty eight,000 to 36,000 cycles/second. The tip moves in an exceeding back-and-forth motion and works on the facet of the tooth, shaving off calculus and rubbish. Here the handpiece, instead of the instrument tip, is activated.
The use of supersonic devices has dramatically improved the observe of supragingival scaling and dental medicine surgical process. though supersonic technology has been around for many years, enhancements in recent years have allowed its use to become thought. supersonic technology generally, whether or not magnetostrictive (long inserts with metal rods that flex) or piezo-electric (small tips that screw onto the handpiece), and sonic scalers to a lesser degree, provide many benefits over hand scaling:
Advantages
•
Fast, effective scaling if used properly - touching & short time on the tooth.
(1) less hand and articulatio radiocarpea fatigue attributable to the sunshine bit necessary to just guide the pulse counter tip on the tooth surface
(2) slashed treatment time, particularly with significant deposits, going longer for patient education or procedures like the placement of therapeutic agents (ie, Arestin [OraPharma], Atridox [Collagenex Pharmaceuticals], or PerioChip [Dexcel Pharma]).
(3) a lot of economical removal of plaque and calculi with supersonic instrumentation
(4) supersonic tip spray promotes elimination of dental plaque
(5) supersonic instruments free the radicular surfaces of microorganism endotoxins whereas protective the cement
(6) less tissue trauma attributable to no sharp cutting edges
(7) water provides continuous tissue irrigation, thereby reducing the necessity for removal throughout scaling since the water flow permits for top visibility throughout the procedure; this irrigation conjointly will increase tissue comfort for the patient throughout and when the procedure
(8) antiseptic resolution may be substituted for the water to produce coincident irrigation/disinfection of the region being treated
(9) wonderful for stain removal that will rather be tedious to scale by hand
(10) gritty, pumice-based polish could not be necessary or indicated the following scaling with ultrasonic; attributable to the economical stain removal throughout scaling, a milder, minimally invasive paste or polish may be used, protective the glaze on composite and ceramic ware restorations; less abrasive polish enhances patient acceptance and lowers post-scaling sensitivity
Subgingival work is feasible with the proper form of the insert (e.g. Focus Spray Insert (FSI), Slimline or Through Flow Insert (TFI)).
(11) less probability of operator injury:
•ultrasonic pulse counter inserts aren't sharp—there are not any cutting edges
•seldom have to be compelled to place tips in AN supersonic bathtub before sterilization, eliminating a step within the handling method
•rarely have to be compelled to scrub supersonic tips, as is commonly necessary for typical hand scalers, more reducing the chance of operator injury
•hand instrument sharpening greatly reduced attributable to lowest usage
(12) patients expertise a better level of comfort; the complete procedure is endured a lot of simply.
Disadvantages
Iatrogenic heat injury to the tooth is feasible if not used fastidiously.
Standard beavertail form tips can't be used subgingivally. For subgingival use, FSI, TFI or Slimline inserts are needed.
Handpieces will heat up significantly throughout long scaling procedures if water pressure isn't consistent. Garden bottle reservoirs usually fail to produce an even and helpful level of water pressure. If AN compressor is on the market, plumbing the unit in provides a far better result.
PIEZO-ELECTRIC TECHNOLOGY
With piezo-electric technology, achieving supersonic mechanical vibration needs the appliance of AN electrical voltage to piezoelectric ceramics. The supersonic energy therefore generated is transmitted via an electrical device contained within the handpiece ANd is prolonged by an electronic equipment. The ensuing benefits of this mechanism embrace increased power management, bigger patient convenience, and high electrical device potency. The axial transmission mode of mechanical waves permits a lot of correct approach to fragile tissues. moreover, there's no cumbersome cooling system necessary.
Piezo-electric scalers specifically have some distinct benefits over several different typical supersonic units. additionally to the antecedently mentioned edges of ultrasonics generally, piezo-electric technology offers the following:
(1) quiet operation
(2) less water is important throughout the procedure, adding to patient comfort and operator convenience; less want for management of excessive water accumulation; less water is needed as a result of the unit’s potency is larger than 90%—there is not any delivered energy or mechanical friction, hence, very little secondary temperature rise; since there's little or no temperature rise, the handpiece may be used while not water. (However, use of sunshine water spray is also fascinating, as this can turn out a cavitation or physicochemical impact.)
(3) less vibration
(4) tiny inserts—less cumbersome to control, a lot of correct placement throughout treatment, increasing patient comfort
(5) versatile supersonic units have varied clinical applications attributable to a comprehensive vary of accessories; additionally, to inserts to be used in scaling and surgical process, several different inserts are on the market for procedures like dental medicine, top surgery, and prosthodontics; dozens of varied inserts are offered that each one work on an equivalent handpiece
(6) junction rectifier natural action lightweight is on the market with some units—much a lot of convenient to assemble and operate than typical natural action lights, saving time, money, and space; the sunshine merely attaches to the unit in situ of the piezo-electric handpiece; excellent for sealing material natural action within the hygiene space further as for restorative materials
(7) light-weight handpiece and hose; simple on the articulatio radiocarpea
(8) may be used for nearly any category of the patient; nice for routine prophylactic procedures further as dental medicine scaling and root planning; a large variety of convenient, skinny insert styles for all potential situations
(9) tiny unit sits on the counter; tiny footprint
(10) convenient, color-coded power dial on some units—coordinates with colored rings on inserts; no guess at the best power setting for every insert, as is usually the case with different supersonic handpieces
(11) inserts for piezo-electric units are typically interchangeable with different makers
(12) easy, convenient barrier protection—intraoral camera sheaths intimately work several piezo-electric handpieces; barrier protection for the unit itself is provided by merely putting a sheet of wrapping loosely over the complete unit; with this in situ, the operator will alter the water and power setting and place the handpiece in its holder while not contaminating the unit, that minimizes the employment of surface disinfectant, which might add time following the procedure and risk damaging the unit
(13) handpiece and inserts are simply removable and autoclavable
(14) piezo-electric inserts take up a lot of less area to store than hand scalers and different dental instruments
(15) the employment of progressive technology helps to strengthen patient relations; communication with patients and educating them regarding the benefits of the piezo-electric pulse counter may be a observe builder; patients feel more well-off throughout the procedure and assured that they're receiving the simplest potential care.
CONCLUSION
The piezo-electric pulse counter may be a staple in our hygiene rooms. Hygienists in our workplace rave regarding our new piezo-electric scalers and, a lot of significantly, patients are terribly complimentary regarding however their mouths feel when their maintenance visits. If you have got the will to maneuver into the planet of electrical scalers, or arable to upgrade, offer hefty thought to the acquisition of a piezo-electric pulse counter.
