| Summary: | Background: Instrumentation on tooth surface for debridement
of hard and soft debris forms the basis of periodontal therapy.
This involves periodic removal of accumulated material using
different methods of instrumentation. An ideal instrument
should eliminate all the deposits from the root surfaces with no
or minimal alteration of the natural morphology.
Aim: To compare the root surface roughness after root planing
performed with gracey curette and by ultrasonic scalers (Satelec
P-5 Booster) set at different power modes.
Materials and Methods: The root surface roughness and its
surface microtopography resulting from the use of Gracey
curette, ultrasonic instrument at low, medium and high power
setting on 35 healthy premolars extracted for orthodontic
treatment purpose were examined using Optical Profilometer
and the surface topography was assessed using Field Emission
Microscope.
Statistical Analysis: Analysis of variance (ANOVA) test was
used to observe the variance in a particular variable is partitioned
into components attributable to different sources of variation.
Duncan multiple range tests were used to determine whether
three or more means differ significantly.
Results and Conclusion: The mean roughness was found to be
the highest in group where Scaling and Root Planing (SRP) was
performed using ultrasonic scaler at low power mode (3.03±1.54
µm) whereas the lowest surface roughness was seen on the
samples where SRP was performed using ultrasonic scaler at
medium power mode. The surface roughness in group where
SRP was performed with ultrasonic scaler at high power mode
(2.22±0.74µm) was found to be similar to that of group in which
root planing was carried out using curette (2.24±1.71µm). |
