The coverage of recessions around teeth is a very successful surgical treatment. The published evidence suggests that periodontal plastic surgeons can very predictably perform these procedures. However, how does reality present? What are the measurement methods and indexes used to support the external evidence? During this lecture, we will look very critically at the evidence we used to support our enthusiasm about the coverage of recession procedures. Second, we will try to answer the raised question in the title of this lecture. Third, the entire thought process will be supported by clinical cases.

Dean Stohler is a leading expert on pain management and on jaw disorders such as temporomandibular joint and muscle disorders (TMJD). He has helped lead National Institutes of Health (NIH)-funded work into the genetics, endocrinology, and neurobiology of the human response to pain—particularly in patients with TMJD, a chronic and painful jaw joint disorder that affects from 5–12 percent of the population. He was a member of the team that was the first to show that thinking that a placebo will relieve pain is enough to prompt the brain to release endorphins, the body’s own painkillers, and that this corresponds with a reduction in how much pain a person experiences. Dr. Stohler’s more than 120 articles and book chapters have been cited more than 5,400 times.
