Oral Prophylaxis made easy
Oral prophylaxis, when thoroughly done, gives so much
satisfaction to the dentist, and the patient feels the difference instantly. In routine
dental practice where six to eight oral prophylaxis cases have to be attended daily, sonic
and ultrasonic scalers are of immense value
Sonic scalers use compressed air and water delivered
through hose designed for high and low speed handpieces. Sonic units consist of a
handpiece that attaches to a compressed air line and uses a variety of specially designed
tips. Air moves rotor system within the scaler that vibrates the working tip in an
elliptical pattern at a frequency of about 2,000 to 6,000 cycles per second(cps). To
remove less tenacious deposits typical of patients treated frequently, this is well
suited, though it is difficult to remove tenacious deposits. E.g.:- Sonicflex Lux (Kavo
America Corp. and Densonic by Dentsply International).
Ultrasonic scalers are of two types.
- Magnetostrictive (e.g.:- Cavitron by Dentsply Intl)
system where electrical energy is applied to coil in the special handpiece which
magnetically changes dimension of a metal stack, creating elliptical movement of the tip
at a frequency of about 25,000 to 30,000 cps. all the sides of the tip are active and will
work when adapted to the tooth. Significant generation of heat necessitates water for
- Piezoelectric (eg:- Piezon Master 400- Shofu and Suprasson
P Max by Satelec) system where electrical energy is applied to a crystal which emits
vibrations in a linear pattern at frequency of about 25,000 to 40,000 cps. In
Piezoelectric units, the pattern of vibration of the tip is linear, or back and forth,
meaning that only the two sides of the tip are active and will work when adapted to the
tooth. There is almost no heat generation and water is for lavage only.
Ultrasonic scalers can remove tenacious deposits.
Advantages of using automated scalers:-
- Decreased chair time.
- Operators fatigue doesnt come in way of
providing a thorough prophylaxis.
- Increased patient comfort.
- Increased operator comfort.
- Simultaneous water lavage and scaling.
- Some systems allow to work with an antiseptic irrigating
- Ultrasonics may interfere with pacemakers.
- Reduced tactile sense.
- Less control in difficult access areas.
- Amount of water coolant necessary for magnetostrictive
systems is more and can be difficult to suction.
- Cost of the system.
- Noise can be irritating to some people.
Suprasson P Max provides both non autoclavable and
autoclavable handpiece and various instrument tips, which, apart from scaling, can do the
functions of root planing, amalgam plugging, prosthesis loosening. root canal preparation
and gutta percha condensation. It has provision to work with an antiseptic irrigating
Myth about prophylaxis: In Asian countries, there is a widespread misconception= "teeth become loose after prophylasis", this
is not at all correct. Oral prophylaxis machine are hight speed and have special tips. In right hands they do not cause any
harm whatsoever to teeth. Routinely this procedure is needed to be carried out every 6-12 months to keep your teeth and gums
in healthy state.
