# The impact of selcopintide on periodontal regeneration in a class II furcation defect model: a radiographic and histomorphometric analysis

## TL;DR

This study shows that Selcopintide can help regenerate periodontal tissues in a specific type of gum defect, with results similar to existing treatments.

## Contribution

The study demonstrates Selcopintide's regenerative potential in periodontal defects, comparable to established treatments like EMD.

## Key findings

- SCPT treatment resulted in significantly greater new bone volume compared to the control group.
- Higher SCPT concentration led to the greatest new cementum formation.
- SCPT outcomes were comparable to enamel matrix derivative treatment in periodontal regeneration.

## Abstract

This study investigated the effect of Selcopintide (SCPT) on periodontal regeneration using surgically created class II furcation defects in an animal model, employing both radiographical and histological evaluations.

Class II furcation defects were surgically induced in six beagle dogs. Each defect was unilaterally and randomly assigned to one of five treatment groups: (1) no treatment (control), (2) guided tissue regeneration (GTR) with a collagenated bone substitute and a collagen membrane, (3) GTR with an enamel matrix derivative (GTR/EMD), (4) GTR with 2 mg/ml SCPT (GTR/SCPT2), or (5) GTR with 4 mg/ml SCPT (GTR/SCPT4). Six weeks after initial surgery, identical procedures were performed on the contralateral area. Healing outcomes were assessed at 6 and 12 weeks through radiographic and histomorphometric analyses. The primary outcome was the length of the root surface covered by new cementum assessed histologically and the secondary outcome included other histomorphometric and radiographic healing outcomes.

Radiographically, the GTR/SCPT groups showed significantly greater new bone volume than the control group at both 6- and 12-week timepoints (p < 0.05). Histologically, specimens treated with both formulations of SCPT displayed better-organized periodontal ligaments and improved cementum formation, similar to those treated with EMD. The group with the highest concentration of SCPT (GTR/SCPT4) exhibited the greatest amount of new cementum formation.

Within the limitations of this study, both formulations of SCPT demonstrated significant regenerative potential in periodontal tissues, with outcomes comparable to those of EMD treatment, suggesting SCPT’s viability as an alternative bioactive agent for periodontal regeneration in class II furcation defects.

This study suggests that SCPT could serve as a viable alternative bioactive agent for periodontal regeneration in class II furcation defect in clinical settings.
