Comparative Evaluation of Periodontal Ligament-associated Protein-1/Asporin Levels in Periodontal Tissue in Health and Disease.

BACKGROUND

Periodontal ligament-associated protein-1 (PLAP-1)/asporin is an extracellular matrix protein that plays a protective role in the pathogenesis of periodontitis. There is a paucity of information about the association between PLAP-1/asporin and periodontitis in human PDL. Thus, in this study, PLAP-1/asporin levels between participants with healthy periodontium and chronic periodontitis were compared and correlated with periodontal parameters.

MATERIALS AND

METHODS

Fifty participants were recruited and divided into 25 in each group: Group 1 (control) and Group 2 (test). Probing pocket depth (PPD) and clinical attachment level (CAL) were recorded. Periodontal ligament (PDL) samples were collected from extracted teeth for estimating PLAP-1/asporin levels using the Human Asporin Enzyme-Linked Immunoassay Kit.

RESULTS

A statistically significant difference (P = 0.001) in the PLAP-1/asporin levels was observed between Group 1 and Group 2. A weak negative correlation was observed between PLAP-1/asporin levels and periodontal parameters (PPD and CAL) in both groups.

CONCLUSION

In this study, higher PLAP-1/asporin levels in participants with healthy periodontium highlight the protective role of PLAP-1/asporin in maintaining periodontal homeostasis.
