Dentalscaling is as important as your daily brushing or flossing.there are some food particles which cannot be remove4d by regular brushing or flossing.
The procedure of hand scaling is more precise and allows better tactile sensation whereas mechanical scaling instruments require less time to remove the deposit and result in less operator fatigue.
Working end can be angled,curved or straight and made up of stainless steel or carbide steel.
Hand scalers come in different varieties like hand scaler, curette,sickle scaler,hoe, chisel and files.Hand scalers have a sharp cutting edge and curette comes with a rounded toe.
They are less effective than ultrasonic scalers but they generate less heat and decreases the chances of iatrogenic damages to the tooth.
Ultrasonic scalers are the most commonly used equipment in a dental clinic nowadays.
These days technology is advancing at a pace of mind where dental experts can modify their technique and makes their technique time saving, an easier and convenient.the very good example of it is the use of NiTi alloy in use of making dental instruments.
In Endodontics, there are NiTi files which are tapered engine-driven and pointed instrument with cutting edges used to mechanically shape and prepare the root canal during RCT or Retreatment cases and in other cases like fractures and alinement of teeth.
It is commonly used in endodontic practice instead of stainless steel due to its super-flexibility and shape memory feature.
The specially designed NiTi files work in a similar but reverse-balanced force action using a pre-programmed motor to move the files in a back and forth reciprocal motion.
They particularly exhibit superelastic behavior between 16-125 degree Celsius.
NiTi alloy comes in hand and rotary files in 2,4,6,8% taper with different length in 21,25,31mm.
