COMPARATIVE ASSESSMENT OF RE-INFECTION & DEGREE OF RESORPTION IN ORTHODONTIC MOVEMENT OF ENDODONTICALLY TREATED TEETH WITHOUT PERIAPICAL INFECTION, WITH PERIAPICAL INFECTION & WITH ASEPTIC PULP NECROSIS BY DENTAL TRAUMA; A PRE-POST OBSERVATIO

It is common practice to relocate teeth that have received endodontic treatment or are undergoing treatment. Facts on inflammation, tissue repair, tooth movement, resorption, pulp diseases, and periapical illness serve as the foundation for clinical decisions and biological orientations. Teeth that have had or are currently undergoing endodontic therapy often need to be moved. External apical root resorption is an iatrogenic side effect of orthodontic therapy, and orthodontics is arguably the only dental specialty that truly leverages the inflammatory process to address functional and aesthetic issues. The objective of this study was to examine the orthodontic movement of endodontically treated teeth with and without periapical lesions, aseptic pulp necrosis from dental trauma, teeth that were vital, and the degree of resorption in each of these cases. Periapical, cephalometric studies and OPG x-rays were used to assess 80 patients in this observational study prior to treatment and at 1-, 3-, 6-, 12 and 24-month intervals to check for re-infection and the extent of resorption in endodontically treated teeth undergoing orthodontic tooth movement. The findings demonstrated that teeth with aseptic pulp necrosis induced by dental trauma had a higher risk of periapical infection recurrence, followed by teeth with an inflammatory periapical lesion. The degree of resorption was also seen to be higher in cases of teeth impacted by dental trauma, with moderate dental trauma resulting in increased root resorption. Vital teeth (control group) demonstrated reduced periapical infection and resorption.
