“…A cone beam computed tomography is the best way to determine if the pulp canal is accessible; furthermore, although modern computed tomography scanners use low doses, they are still higher than conventional radiographs (12). Because the diagnosis was made using an image that was not as precise as the CBCT, the decision to perform the surgery was delayed by 1.5 years, during which time we carried out biannual radiographic monitoring and verification of the evolution of apical rarefaction of the right central incisor.…”

Tooth avulsion represents the most complicated dental injury, and the classic treatment is tooth replantation. The most common sequelae are pulp canal calcification (PCC) and pulp necrosis. The presence of pulp necrosis after PCC is reported in up to 30% of the cases and is a challenge due to the difficulty of endodontic treatment. This case report describes the surgical treatment of a replanted tooth presenting PCC and periapical pathology eight years after the trauma. An endodontic surgery was performed to remove the apical granuloma, to prepare the apical root, and to seal the apical region with an endodontic cement. In a three-year follow-up, there was an absence of inflammatory signs and symptoms or apical lesion. This report shows the importance of close follow-up after dentoalveolar injuries. After the initial dental trauma and its consequences to pulpal tissues, the executed procedures allowed a favourable outcome.

“…Buchgreitz et al evaluated ex vivo the accuracy of a preparation procedure planned for teeth with root canal obliteration using a guide rail concept based on CBCT scan merged with an optical surface scan and the mean distance between the drill path and the target was significantly lower than 0.7 mm and Zehnder et al concluded that deviations of planned and prepared access cavities were low with means ranging from 0.16 to 0.21 mm for different aspects at the base of the bur and 0.17–0.47 mm at the tip of the bur and the mean of angle deviation was 1.81° . In the field of endodontics, the use of guided splints assisted by CBCT has been documented for treating dens invaginatus and teeth with root canal calcification and apical pathology; this lack of precision can make it difficult to locate the root canals and may lead to unexpected complications.…”

Anderson J, Wealleans J, Ray J. Endodontic applications of 3D printing. International Endodontic Journal.Computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies can leverage cone beam computed tomography data for production of objects used in surgical and nonsurgical endodontics and in educational settings. The aim of this article was to review all current applications of 3D printing in endodontics and to speculate upon future directions for research and clinical use within the specialty. A literature search of PubMed, Ovid and Scopus was conducted using the following terms: stereolithography, 3D printing, computer aided rapid prototyping, surgical guide, guided endodontic surgery, guided endodontic access, additive manufacturing, rapid prototyping, autotransplantation rapid prototyping, CAD, CAM. Inclusion criteria were articles in the English language documenting endodontic applications of 3D printing. Fifty-one articles met inclusion criteria and were utilized. The endodontic literature on 3D printing is generally limited to case reports and pre-clinical studies. Documented solutions to endodontic challenges include: guided access with pulp canal obliteration, applications in autotransplantation, pre-surgical planning and educational modelling and accurate location of osteotomy perforation sites. Acquisition of technical expertise and equipment within endodontic practices present formidable obstacles to widespread deployment within the endodontic specialty. As knowledge advances, endodontic postgraduate programmes should consider implementing 3D printing into their curriculums. Future research directions should include clinical outcomes assessments of treatments employing 3D printed objects.
