Much of clinical practice regarding "Tethered Oral Tissues" has been based on belief rather than on science. Given we are duty-bound to practice according to the evidence, Dr. Hazelbaker examines the scientific research literature on "TOTs" from the past 5 years. She answers the questions: What is new? What is good quality? What can we apply to clinical practice? What should we ignore? Participants will come away with a better understanding of which scientific research on "TOTs" should inform clinical practice.




The participant will be able to:


1.Describe the basic principles of good research study design.

2.Describe the major failings of “tethered oral tissues” research.

3.Discuss at least three good studies and their impact on clinical practice.


l.  Study design: a review of the basics
    a.   What is evidence-informed practice?
    b.   Hierarchy of evidence
    c.   How to tell a good study from a bad one based on methodological considerations


ll. The “TOTS” Research: 2018-the present

    a.   Tongue-tie including the enigmatic posterior tie
    b.   Maxillary lip-tie
    c.   Buccal tie
    d.   Miscellaneous claims and considerations in the research
    e.   Gamechanger studies we should really pay attention to


lll. Clinical Implications of the “TOTs” Research

    a. Which studies belong in the round file?
    b. Which studies should we consider as a jumping off place for more research before changing clinical practice?
    c. Which studies should inform our clinical practice?
