Abstract
A method of and apparatus for diagnosing the presence and extent of disease activity within a periodontal pocket. A dual electrode probe having a first, working silver electrode and a second, reference silver/silver chloride electrode is inserted into the pocket to take data measurements of the electrochemical potential between the electrodes while they are immersed in the fluid contained in the periodontal sulcus. The strength of the potential reflects the amount of sulfides within the sulcus fluid and reflects the presence and extent of disease therewithin.
