Perio2 (Lecture 3) : Exam, Dx, and Imaging

Many of the “rules” of periodontal therapy have been changed forever, with a paradigm shift from the practice of saving teeth at all costs toward one that will consider the extraction of “maintainable” teeth to improve esthetics, function and long term success of implant restorations.
