| dc.description | Background: Dental concrescence (DC) is an anomaly of dental development where the roots of two or more adjacent teeth are joint by root cement1,2. It has a prevalence of 0.2 - 3.7% in primary dentition and 0.8% in permanent dentition1-6. It is usually diagnosed during tooth extraction or as a radiographic finding3,7. This anomaly can affect the planning and outcome of endodontic, periodontal, prosthodontic, orthodontic, and extractions treatments4,6. Clinical Presentation: Male patient, 18 years old, shows up at the dental office for orthodontic evaluation. The d.D.S requested a panoramic radiography, in which semi-included 2.7 was observed with a projected root in the distal root zone of 2.6. After radiographic finding, a CBCT of 2.6-2.7 area was requested with a FOV of 4x4 cm and a voxel size of 125 μ to evaluate possible impaction of said molars. Individual axes of each root were corrected, and a multiplanar evaluation of the area under study was performed, showing tooth 2.6 with great bone defect and distal furcation involvement, with long and divergent roots. Partially erupted tooth 2.7 with mesiobuccal root (MB) with hypercementosis and mesial profile fused with the distal surface of the distobuccal root (DB) of tooth 2.6 in its apical third. Images were compatible with DC amid teeth 2.6-2.7. Clinical Relevance: DC occurs exclusively in the posterior maxillary area, mainly among the maxillary second and third molars3,4,9,10. In the present case, teeth involved were in the posterior maxillary region but corresponded to a first and second molar.DC is usually diagnosed during tooth extraction or as a radiographic finding since its clinical detection is practically impossible3,4,6,7,9. Given the limitations inherent to two-dimensional radiographic images, such as distortion and superposition of structures, the use of CBCT is extremely useful, since it eliminates these limitations and allows a three-dimensional examination, thus improving diagnostic precision3,5,6,8 -10. Conclusion: Given the suspicion caused by a two-dimensional image, the indication of CBCT provides relevant information for the correct and precise diagnosis of DC, and its subsequent treatment-planning, minimizing risks associated. | en-US |
| dc.description | Antecedentes: La concrescencia dental (CD) es una anomalía del desarrollo dentario, las raíces de dos o más dientes adyacentes se unen por cemento radicular1,2. Tiene una prevalencia de 0,2 - 3,7% en dentición primaria y 0,8% en dentición permanente1-6. Suele diagnosticarse durante la exodoncia o como hallazgo radiográfico3,7, afecta la planificación y resultado de tratamientos odontológicos4,6.Presentación Clínica: Paciente sexo masculino, 18 años, se solicita radiografía panorámica, se observa el diente 2.7 semi incluido con raíz proyectada en la zona radicular distal del diente 2.6. Se solicita CBCT zona 2.6-2.7. Se corrigieron los ejes individuales de cada raíz y se efectúo evaluación multiplanar de la zona, evidenciándose diente 2.6 con amplio defecto óseo y compromiso de furca por distal, raíces largas y divergentes. Diente 2.7 semierupcionado, raíz mesiovestibular (MV) con hipercementosis y perfil mesial fusionado con superficie distal de raíz distovestibular (DV) del diente 2.6 en su tercio apical. Imágenes resultaron compatibles con CD entre dientes 2.6-2.7Relevancia Clínica: La CD se presenta comúnmente en la zona maxilar posterior, principalmente entre segundos y terceros molares.3,4,9,10 En este caso, los dientes involucrados se encuentran en la región posterior maxilar, pero corresponden a un primer y segundo molar. Suele diagnosticarse durante la extracción dental o como hallazgo radiográfico, ya que, su detección clínica es prácticamente imposible.3,4,6,7,9 Dadas las limitaciones de las imágenes radiográficas bidimensionales, como distorsión y superposición de estructuras, el uso de CBCT es de utilidad, puesto que elimina estas limitaciones y permite una exploración tridimensional, mejorando así la precisión diagnóstica.3,5,6,8-10Conclusión: Ante sospecha en la imagen bidimensional, la indicación de examen CBCT resulta relevante para el diagnóstico correcto y preciso de CD y posterior planificación del tratamiento, minimizando los riesgos asociados a este. | es-ES |
