2022 IADR/APR General Session
The 100 th General Session & Exhibition of the IADR was held in conjunction with the 5th Meeting of the Asia Pacific Region. The virtual meeting was attended by individuals from around the world. Those attending the meeting could choose from among 207 Interactive Talk sessions, seven Focused Learning Sessions, three Hands-on Workshops, five satellite symposia, 52 Symposia, one Distinguished Lecture Series and a plenary.The recordings in this library from the meeting are a selection of the science that was to be presented as part of the General Session. These recordings give you the opportunity to participate in the meeting and hear from leading researchers. The recordings include the IADR Distinguished Lecture Series speaker and symposia from a collection of scientific groups and networks.
This session can be purchased as part of the full meeting recordings within the product bundles

Session Description
Recent studies in dental root development have identified several signaling pathways that are necessary for and specific to the growth and development of normal dental roots. Experimental animal models that are deficient in some of these signaling proteins have demonstrated a variety of root formation anomalies. Additional studies of these animal models as well as human genetic studies may allow us to determine the underlying causes of these developmental aberrations.
One such aberration that is of interest is known as Short Root Anomaly (SRA). SRA, as its name implies, is characterized by roots that are developmentally shorter than normal. The number of roots affected is variable, but it is usually bilateral. There is an increased incidence in patients of Mexican descent. It will be important to evaluate the variance in incidence and heritability of this anomaly.
Orthodontic tooth movement is known to produce some degree of root resorption. In most cases, the amount of resorption is not clinically significant. However, if the patient presents with shortened roots before treatment, even small amounts of resorption can become clinically significant. It will be imperative for orthodontists to know what changes in treatment planning and biomechanics are necessary in order to treat these patients without causing premature loss of teeth due to lack of periodontal support.
