Periodontal Instruments

🔹 A general rule for working end selection is that the lower shank should be parallel to the surface to be instrumented.

🔹 Instruments with straight shank are used in anteriors and premolars whereas instruments with contra-angle are used on posterior teeth.

🔹 Chisel is the only instrument which is activated with a push motion.

🔹 The beaks of a needle holder are shorter and stronger than the beaks of a hemostat.

🔹Novatech probes: These are the probes with unique right angle design for improved adaptability in the posterior.

🔹Expros are double end instrument with an explorer on one end and probe on other, e.g. 17/Williams, 23/0 Michigan, 23/Williams.

🔹Merritt and Gilmore periodontal probes are not calibrated probe.

🔹 The aerosol which are produced by ultrasonic scaling remains in the air for minimum of 30 minutes.
