low-level laser therapy platelet-rich plasma bone calcium content mechanical properties LLLT PRP

TLDR Low-level laser therapy improved bone strength after tooth extraction, but calcium content was unchanged.

This animal study evaluated the effects of low-level laser therapy (LLLT) and platelet-rich plasma (PRP) on bone calcium content and mechanical properties at tooth extraction sites in 20 male rats. The study found that LLLT significantly increased the mechanical strength of bone blocks compared to the control and PRP-treated groups, with P-values of 0.0001 and 0.00044, respectively. However, neither PRP alone nor in combination with LLLT showed a synergistic effect on mechanical strength or calcium content. Calcium content was not significantly affected by any of the treatments.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 1 year ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
