Factors impacting outcomes in nonsurgical reinstrumentation

Investigators may have identified the tooth-related factors contributing to nonsurgical reinstrumentation outcomes.

In a retrospective study published in the Journal of Periodontology, the investigators examined 10,807 teeth in 480 patients who exhibited residual pockets following the first and second steps of periodontal therapy.

The investigators found that tooth type, arch, number of roots and presence of bleeding on probing were significantly associated with improvements in pocket probing depth and pocket closure. Further, moderate pockets were more likely to respond to treatment with nonsurgical reinstrumentation compared with deep pockets.

The investigators encouraged clinicians to consider these factors when assessing patients as part of step three of periodontal therapy. The findings may help inform less-invasive treatment options and more personalized care strategies.
