According to Lindhe et al (1982), what is the effect of scaling and root planing (SRP) on attachment for pockets shallower than 2.9 mm?

The research conducted by Lindhe et al. in 1982 investigates the impact of scaling and root planing (SRP) on periodontal attachment, particularly in relation to pocket depths. For pockets shallower than 2.9 mm, the findings suggest that scaling and root planing do not lead to significant changes in attachment levels, which is key in understanding periodontal therapy outcomes.

In cases where pockets are shallow, the existing biological and structural conditions of the periodontal tissues may not necessitate extensive intervention, as there is often minimal calculus or plaque contributing to attachment loss. As a result, scaling and root planing may result in maintaining existing attachment levels rather than actually creating any notable gain or healing beyond what is already present.

The correct interpretation aligns with the understanding that shallow pockets may remain stable through thoughtful and conservative periodontal maintenance. Although the interpretation of attachment dynamics can vary in different clinical circumstances, the prevailing conclusion from the study illustrates that for pockets of this depth, scaling and root planing may primarily result in no significant alteration in attachment, rather than loss or gain.
