Periodontal Probes
They are used to locate, measure and mark pockets, as well as determine their course on individual tooth surfaces.
Explorers
Used to locate calculus deposit and caries
Scaling, Root Planning and Curettage Instruments
They are used for removal of plaque and calcified deposit from crown and root of tooth, removal of altered cementum from subgingival root surface, and debridement of soft tissue lining the pocket. Scaling and curettage instruments are classified are:
“Risk Factors For Improper Use Of Periodontal Probes”
- Sickle scalers are heavy instruments use to remove supragingival calculus.
- Curettes are fine instruments used for subgingival scaling, root planning and removal of soft tissue lining the pocket.
- Hoe, chisel and file scalers are used to remove tenacious subgingival calculus and altered cementum. Their use to limited as compared to curettes.
- Ultrasonic and sonic instruments are used for scaling and cleansing tooth surfaces and curetting the soft tissue wall of periodontal pocket.
Periodontal Endoscope
It is used to visualize deeply into subgingival pocket and furcations, allowing the detection of pockets.

Cleansing and Polishing Instruments
These are rubber cups, brushes and dental tape, they are used to clean and polish tooth surfaces. Also available are air-powder abrasive systems for tooth polishing.
