“…When comparing the findings of periapical radiographs and CBCT, most of the replacement and cervical root resorptions detected in this study are not visible using 2D imaging (Table 3). This is corroborated by existing research, where CBCT yielded higher sensitivity than intraoral radiographs in the diagnosis of external root resorptions [39,40]. However, findings deemed inconclusive by the PI were found more frequently in the assessment of CBCTs than of PAs.…”

Objectives To assess survival rates and frequency of complications for immature and mature autotransplanted teeth after at least 1 year in function. Materials and methods All consecutive patients who had undergone tooth autotransplantation between 2000 and 2018 were invited to a clinical and radiographic follow-up examination. First, survival rates were calculated on the basis of a phone inquiry. A clinical follow-up examination allowed for the calculation of the success rate, i.e., absence of any potentially adverse clinical and radiographic findings of the autotransplanted teeth. Moreover, the effect of demographic, dental, and surgical variables on survival/success was analyzed statistically. Results Thirty-eight teeth in 35 patients were transplanted during the study period. Three teeth in 3 patients were excluded due to missing records. All other patients were successfully contacted and interviewed by phone. Out of these 35 transplants, 32 were still in function, and 3 had been extracted, yielding a 91.4% survival probability after a median follow-up of 3.4 years. Of the 32 teeth qualifying for the success analysis, 20 (62.5%) showed absence of potentially adverse findings, while 3 (9.4%) required root canal treatment (RCT). Out of the 9 mature, root-end resected transplants, 4 exhibited ongoing pulp canal obliteration, all with a single root canal. Postoperative and potentially adverse findings or failures were found more frequently in the group of mature transplants (55.6%) than immature transplants (30.4%) and for molars (72.7%) than premolars (17.6%) or canines (25%). None of the potential predictors had a statistically significant effect on survival or success. Conclusion Autotransplanted teeth yielded a satisfying midterm survival rate regardless of their stage of development. An additional, extraoral root-end resection of mature transplants may lead to rates of revascularization and postoperative pulp canal obliteration higher than the data reported on unmodified mature transplants. Clinical relevance Extraoral root-end resection of mature teeth shows promising outcomes for transplants especially with a single root canal and uncomplicated root morphology.

“…On the other hand, three-dimensional CBCT has high sensitivity and slightly lower specificity in relation to diagnosis of foci of ankylosis ( Fig. 4) (38). Ankylosis of a canine positioned inside the bone has also been considered as an indication for its extraction, if there are no conditions to conduct autotransplantation (37).…”

Orthodontic movement of a maxillary canine into the dental arch may be a therapeutic challenge, and it is necessary to analyse a case in detail and to evaluate therapeutic methods, including a difficult decision of tooth extraction in all cases. Aim. The paper aims to discuss orthodontic indications for maxillary canine extraction based on available literature. Material and methods. The PubMed database and the following key words were used for studies: canine impaction, maxillary impacted canine and canine extraction. Literature was supplemented with publications from reviewed journals not included in the PubMed database. 50 papers were selected from the literature list. Results, review and discussion. A decision to extract a maxillary canine should be made based on a detailed clinical examination and analysis of orthodontic records, including photographs, diagnostic models and radiological scans. CBCT imaging test should be performed as standard before treatment in case of impaired tooth eruption. Factors that should be especially considered include: tooth anatomy, periodontal status, position in the bone, occlusion, condition of the adjacent teeth and any pathological processes in the tooth vicinity. Before making a therapeutic decision a patient should be informed about available therapeutic options according to current medical knowledge, as well as about advantages and disadvantages of each of them. Summary. Factors favouring extraction of impacted canines or canines with impaired eruption include: unfavourable position (a horizontal position of a tooth in the bone, position in the zone IV and V according to Kurol, large distance from the edge of the alveolar process), anatomical abnormality (root angulation, external or internal resorption), root ankylosis, patient’s age above 30 years and good occlusion without a canine in the dental arch with the need to extract a premolar for its movement into the dental arch.

Diagnosis of tooth ankylosis using panoramic views, cone beam computed tomography, and histological data: a retrospective observational case series study

Abstract: CBCT images can be a useful adjunctive diagnostic tool to diagnose ankylosed teeth, but cannot be recommended as a single diagnostic modality as false positive results were found.
