Root planing following short-term pocket distention

Area of Science:

• Periodontology
• Dental calculus removal
• Root planing techniques

Background:

• Subgingival calculus removal is crucial for treating periodontal disease.
• Effectiveness of root planing in deep pockets can be challenging.
• Gingival retraction methods may influence instrumentation access.

Purpose of the Study:

• To evaluate the efficacy of root planing after short-term pocket distention.
• To compare calculus removal with and without gingival retraction cords.
• To determine the effect of aluminum sulfate in retraction cords on calculus removal.

Main Methods:

• Seventy-five teeth with probing depths of 5-10 mm were divided into three groups.
• Groups 1 and 2 used aluminum sulfate-impregnated and non-impregnated cords, respectively, for 30 minutes before scaling and root planing.
• Group 3 underwent root planing only.
• Residual calculus was quantified using computerized image analysis after extraction.

Main Results:

• Overall, 46.3% of root surfaces had residual calculus (mean 4.41%).
• Groups using retraction cords (1 and 2) showed significantly less residual calculus (3.03% and 3.04%) compared to the control group (7.15%).
• No significant difference in calculus removal was observed between the impregnated and non-impregnated cords.

Conclusions:

• Short-term pocket distention using gingival retraction cords enhances subgingival calculus removal during root planing.
• The presence of aluminum sulfate in retraction cords does not provide additional benefit for calculus removal.
• These findings suggest improved access and effectiveness in deep periodontal pockets with this technique.
