Control radiográfico de trasplante dentario: reporte de caso / Radiographic control of dental transplantation: a case report

El trasplante dentario es una opción terapéutica para reemplazar un órgano dental perdido, causado por un proceso carioso extenso, agenesia, trauma-tismos o iatrogenias. Este procedimiento quirúrgico traslada un órgano dental íntegro desde un alveolo donante hacia su lecho receptor; para lo cual debe poseer ciertas características que permitan tener un pronóstico favorable a largo plazo. El presente estudio describe la evolución de un trasplante dental autólogo realizado hace 14 años a una paciente que acudió a la consulta para valoración del órgano den-tal 4.7, el que presentó un pronóstico desfavorable, por lo cual se realizó exodoncia y trasplante inme-diato del diente vital 4.8 al alveolo del órgano dental 4.7. Tras la planificación quirúrgica se procedió con la intervención conservando la vitalidad pulpar del diente a ser trasplantado, se realizó control clínico y radiográfico a los 15 días, 30 días, 6 meses, 1 año, 5 años y 14 años, en el que se observó conservación del paquete vasculonervioso y ligamento periodontal del órgano dental; a su vez se pudo evidenciar rizo-génesis en el diente trasplantado y un aumento de la altura del proceso alveolar, mediante mediciones realizadas en Auto CAD 2023 (AU)

Tooth transplantation is a therapeutic option to re-place a lost dental organ, caused by an extensive carious process, agenesis, trauma or iatrogenesis. This surgical procedure transfers a complete den-tal organ from a donor alveolus to its recipient bed; for which it must have certain characteristics that allow it to have a favorable long-term prognosis. The present study describes the evolution of an autolo-gous dental transplant carried out 14 years ago to a female patient who attended the consultation for evaluation of the dental organ 4.7, the same one that presented an unfavorable prognosis, for which an extraction and immediate transplantation of the 4.8 vital tooth was performed to the alveolus of the den-tal organ 4.7. After surgical planning, the intervention was carried out preserving the pulpal vitality of the tooth to be transplanted; clinical and radiographic control was performed at 15 days, 30 days, 6 months, 1 year, 5 years and 14 years, in which preservation of the vascular-nervous bundle and periodontal liga-ment of the dental organ was observed; in turn, rhizo-genesis in the transplanted tooth and an increase in the height of the alveolar process could be evidenced, through measurements made in Auto CAD 2023 (AU)

Nonsurgical management of endodontic iatrogeny using mta plug: A case report

Endodontic treatment confronting previous iatrogeny in teeth with incomplete root formation and apical periodontitis is presented as a challenge to the Endodontists. The sanitization and peri-radicular repair can be achieved by the assist of auxiliary materials to biomechanical treatment procedures. MTA is cogitated as a choice for these cases due to its composition, physicochemical, mechanical and biological properties. In this case report, the patient presented tooth 11 with incomplete root formation and peri-radicular radiolucent lesion accompanied by the presence of an inverted gutta-percha cone in an attempt to filling the root canal. Endodontic treatment was accomplished by removal of the previous gutta-percha. After determining the working length, biomechanical preparation was achieved up until #80 K-file. Sequentially application of calcium hydroxide, as intracanal medication, was performed. Six monthly exchanges of intracanal dressing were completed. Apex was sealed with MTA bonded with saline through #4 Paiva condenser, creating an apical plug. The tooth was temporarily sealed, and patient returned after a week to perform the root canal filling with gutta-percha associated to Sealapex. The final radiography shows apical tissue repair with no peri-radicular lesions and clinical signs of successful treatment. This case report highlights the tissue repair and lack of local infection, absence of sensitivity pain or edema. These findings indicated that these approaches could be elect to presence of necrotic lesions achieving tissue repair.
