I outline the value of randomized trials and revisit the findings of some of the main studies I have completed. We must also consider the development of patient-relevant outcomes and core outcome sets. While we recognize the value of trials, we must also recognize that evidence-based care is undermined by claims from the orthodontic fringe.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Tension currently exists between the evidence-based orthodontic approach and the low-quality evidence provided by the orthodontic fringe. This paper provides an overview of these two views. The solution to this dilemma lies in carrying out high-level research and making the findings relevant and understandable to our patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ejo\/cjag071","type":"journal-article","created":{"date-parts":[[2026,10,13]],"date-time":"2026-10-13T10:02:43Z","timestamp":1791885763000},"source":"Crossref","is-referenced-by-count":0,"title":["Sheldon Friel lecture 2026.
