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.
