Optical approach for monitoring the periodontal ligament changes induced by orthodontic forces around maxillary anterior teeth of white rats
Abstract Structural variations of the periodontal ligament (PDL) induced by orthodontic forces have been evaluated by optical coherence
tomography (OCT) and compared to images obtained by conventional radiography. Here, two specially designed orthodontic appliances
were installed on the maxillary anterior teeth of white rats for applying different magnitudes of orthodontic forces. Constant
distraction force magnitudes of 0, 5, 10, and 30 gf were given to four respective rats over a period of 5 days. At the end
of the treatment period, the rats were sacrificed and the maxillaries were extracted for X-ray and OCT imaging. The PDL variations,
proportional to ...
