Electronic PRI consistency in diagnosing temporomandibular joint dysfunction.
Pantographic reproducibility was compared using electronic and mechanical pantographs. The scores were calculated electronically or manually by a single scorer. It can be concluded that (1) with 65.4% of dysfunction-free patients, the electronic pantograph is more consistent than the mechanical pantograph within sessions and over time in recording PRI dysfunction, (2) operators with varying experience need not cause P-PRI fluctuations with dysfunction-free patients, and (3) PRI fluctuations can be caused by temporomandibular joint dysfunction.
