Influence of polishing procedures on sonic scaling root surface roughness

Area of Science:

• Dentistry
• Biomaterials Science

Background:

• Sonic scaling can induce surface roughness on tooth root surfaces.
• Root surface integrity is crucial for periodontal health and healing.

Purpose of the Study:

• To evaluate the effectiveness of different polishing techniques in minimizing root roughness after sonic scaling.
• To compare the efficacy of air-powder polishing versus pumice in root surface debridement.

Main Methods:

• In vitro study using extracted teeth subjected to sonic scaling.
• Profilometry used to measure root roughness (Ra) before and after polishing.
• Two polishing groups: Group 1 (air-powder, rubber cup/chalk) and Group 2 (pumice, chalk).

Main Results:

• Root roughness measurements were lower when the profilometer stylus moved perpendicular to the scaling direction.
• Both polishing groups significantly reduced root roughness (Ra) at each stage.
• The final root roughness reduction was comparable between the air-powder and pumice polishing groups.

Conclusions:

• Both pumice and air-powder polishing are effective in reducing root roughness induced by sonic scaling.
• The choice of polishing agent does not significantly impact the final outcome in terms of roughness reduction.
• These findings support the use of these polishing methods for root surface decontamination.
