This study is about a treatment for a jaw condition called temporomandibular joint (TMJ) subluxation. In this condition, the jaw can move too far forward during mouth opening, which may cause repeated jaw locking and problems with normal function.
The treatment being studied is platelet-rich plasma (PRP) injections. PRP is made from a person's own blood and may help improve joint stability and reduce symptoms.
In this study, 40 adults with TMJ subluxation were randomly assigned to receive PRP with either a lower or higher platelet concentration. Each participant received 2 injections, given 2 weeks apart.
The study measured jaw pain, how often locking happened, mouth opening, and joint clicking before treatment, after 6 months, and after 5 years.
The goal of this study is to find out whether the amount of platelets in PRP changes how well this treatment works.
