Introduction

Temporomandibular joint (TMJ) hypermobility affects broad demographic, challenging the efficacy of traditional treatments. The aim of this study is to investigate therapeutic potential of autologous blood injections (ABI) vs dextrose prolotherapy in rabbit model, through detailed histopathological & radiological analyses.

Material and Methods

After ethical approval from the institutional committee, a hypermobile joint model was established in rabbits through surgery affirmed by MRI. Subsequently, rabbits were randomly divided into two groups i.e. ABI and dextrose solution. In each group, one joint was designated as control, treated with saline. Following surgical induction of TMJ hypermobility, treatments were administered, & outcome was assessed through histological examination for fibrosis grading & CD68 staining for macrophage infiltration.

Results

The ABI group exhibited a higher fibrosis grade (> 75% in 50% of joints) & stronger CD68 staining, indicating a significant fibrotic response & macrophage infiltration compared to dextrose group. In contrast, control joints displayed no fibrosis grades & negative CD68 staining.

Conclusion

The study highlights both ABI & dextrose prolotherapy elicit significant fibrotic responses in treating TMJ hypermobility, indicating their therapeutic mechanisms. ABI in particular, triggers more marked inflammatory reaction, underscoring its potential efficacy. Further evaluation is essential to understand its clinical significance and applicability in managing TMJ disorders.
