Summary
Root instrumentation during scaling and root planing causes trauma, averaging 0.76 mm of attachment loss. Different instruments, including mini-curettes and conventional curettes, did not significantly alter this trauma level.
Area of Science:
- Periodontology
- Dental Instrumentation
Background:
- Periodontitis requires scaling and root planing (SRP) to manage inflammation and attachment loss.
- The instrumentation phase of SRP can potentially cause trauma, affecting periodontal attachment levels.
Purpose of the Study:
- To clinically evaluate the immediate effect of instrumentation trauma after SRP using different instruments.
- To compare the trauma induced by Gracey mini-curettes versus conventional Gracey curettes.
Main Methods:
- Ten subjects with moderate chronic periodontitis were selected.
- Teeth were randomly assigned to receive SRP with either mini-curettes (MC group) or conventional curettes (CC group).
- Relative attachment level (RAL) was measured immediately before and after instrumentation using a computerized electronic probe.
Main Results:
- Both MC and CC groups showed statistically significant increases in RAL immediately before and after instrumentation (p < 0.05).
- The average trauma from instrumentation was 0.68 +/- 0.32 mm for the MC group and 0.83 +/- 0.41 mm for the CC group.
- No statistically significant difference in trauma from instrumentation was observed between the MC and CC groups.
Conclusions:
- Root instrumentation during SRP results in an average trauma of 0.76 mm.
- The type of instrument used (mini-curettes vs. conventional curettes) did not significantly influence the degree of trauma from instrumentation.
