As dentistry has evolved, so has orthodontics.  This program will examine the current developments in orthodontics and how they impact treatment. 

The topics will include:

The use of temporary anchorage devices (TAD's)

The indications and use of accelerated orthodontics

Root resorption and orthodontic movement

Primary failure of eruption and ankylosis

The use of CT imaging in orthodontics

Micro-computed tomography (micro-CT), like conventional tomography, uses X-rays to create cross-sections of a 3D-object that later can be used to recreate a virtual model without destroying the original model. A micro-focus X-ray source illuminates the object, and a planar detector collects magnified projection images. Based on hundreds of angular views acquired while the object rotates, a computer synthesizes a stack of virtual cross-section slices through the object. The term micro is used to indicate that the pixel sizes of the cross-sections are in the micrometer range. This also means that the machine is much smaller in design compared to the tomographic hospital devices, and is used to model smaller objects. This non-destructive method allows to scroll through the cross-sections, interpolating sections along different planes, inspect the internal structure, measure 3D morphometric parameters, create realistic visual models, with no sample preparation, no staining, and no thin slicing. The first micro-CT system was conceived and built by Jim Elliott in the early 1980s. The first published X-ray microtomographic images were reconstructed slices of a small tropical snail, with pixel size about 50 micrometers. In endodontics, Tachibana & Matsumoto (1990) investigated the application of X-ray computed tomography and found that 3D reconstruction of teeth was feasible, but a spatial resolution of 0.6 mm produced images that were not really fine enough for detailed analysis. Five years later, Nielsen et al. (1995) evaluated the  potential  of  the micro-CT  as an  advanced  system  for  detailed  endodontic  research. Since then, micro-CT has been used as a valuable tool in endodontic research. The aim of this presentation is to describe the most recent advances in micro-CT imaging in endodontics.

Key learning points

- New technologies and techniques have been explored to assess root canal geometry and anatomical changes after canal preparation;
- Three-dimensional methods, which make possible observations from arbitrary viewpoints, are replacing two-dimensional methods for the morphological study of dental pulp cavities;
- X-ray microtomography is a technique that allows three-dimensional images of canal geometry to be obtained before and after an endodontic treatment;
- Micro-CT scanner employs cone-beam geometry and produces true 3D reconstructions of the object with cubic voxels and isotropic resolution.

"Current Status of Regenerative Endodontics"

Considerable excitement exists for developing dental applications that employ post-natal stem cells and concepts of tissue engineering.  Although much remains to be done to advance this field, progress has been made in clinical regenerative endodontic procedures:  literally, saving teeth by regenerating a pulp-dentin complex.  This program will describe the current status of regenerative endodontic procedures, their potential and predictors of healing success.  Both clinical and basic studies will be reviewed to provide the practitioner with the latest information on this field with an emphasis on practical steps to be apply these procedures in treating selected patients. 

Objectives:

At the completion of this course, the practitioner should be able to:

1.    Describe the three major steps in tissue engineering and how they apply to regenerating the pulp-dentin complex.

2.    Understand the clinical principles needed for regenerative endodontic procedures.

3.    Be able to describe clinical outcomes of successful regenerative endodontic procedures.
