Management of an unerupted tooth and odontoma after trauma in predecessor

The purpose of this case report was to describe the surgical exposure and orthodontic management of an unerupted and ectopic maxillary right central incisor after trauma to the primary predecessor. Case report: An 11-year-old girl was referred to the Pediatric Dentistry Clinic due to eruption failure of the maxillary right central incisor. Radiographs showed the impacted central incisor located below the anterior nasal spine and its apex parallel to the palatal plane and the presence of an odontoma. General surgery was performed to remove the odontoma and two perforations in the crown of the impacted tooth were made to carry out orthodontic traction. Correct alignment was achieved after 18 months and no significant clinical or radiographic alterations were founded. Conclusion: The orthodontic management was performed successfully, and a positive esthetic outcome combined with adequate occlusion demonstrated the satisfactory results of this case.

Tercer molar superior retenido en seno maxilar. Presentación de un caso / Third Upper Molar Retained in Maxillary Sinus. Presentation of a Case

Se presentó una paciente de 38 años de edad, mestiza, la cual acudió a Consulta de Cirugía Maxilofacial del Hospital Lenin remitida del Servicio de Neurocirugía, que refirió ser objeto de varios estudios de cráneo (incluyendo TAC) por presentar cefaleas mantenidas de moderada a gran intensidad.

Refirió que recibió tratamiento farmacológico para aliviar los síntomas dolorosos, además, describió otros signos y síntomas como: caída del cabello, afectaciones visuales del lado derecho (visión borrosa, molestias), dolor facial difuso y edema en hemicara derecha. Al examen físico nada a señalar, con rayos x de senos paranasales se diagnosticó la presencia de un tercer molar incluido en seno maxilar derecho. La paciente fue llevada al salón de forma electiva y mediante la técnica de Caldwell-Lud fue extraído dicho molar. La paciente evolucionó de manera favorable.

Quiste dentígero: reporte de casos / Dentigerous cyst: case report

El quiste dentígero es un hallazgo clínico casual, ordinariamente asociado con la alteración en la erupción de caninos,premolares y terceros molares que pueden no estar presentes al examen clínico, especialmente después de la época de erupción normal de los dos primeros tipos de dientes mencionados. Su diagnostico se realiza durante la exploración radiográfica de rutina (Rx panorámica) en Odontología. Un espacio folicular mayor de 3 mm alrededor de la corona de un diente no erupcionado es un criterio razonable para diagnosticar la lesión como quiste dentígero. El quiste dentígero es considerado el segundo quiste odontogénico que con mayor frecuencia se identifica en los maxilares y representan el 24 de los quistes de la mandíbula, su mayor incidencia se presenta entre la segunda y tercera década de la vida. Se caracteriza por ser asintomático, aunque la expansión y adelgazamiento de las corticales del área involucrada puede llegar a producir asimetrías faciales. Con el paso del tiempo, dado el continuo crecimiento, es factible encontrar reabsorciones radiculares de dientes contiguos, dolor, parestesia, hiperplasia gingival, infección, fístula y fractura patológica. Por el riesgo que significa su presencia y evolución, se recomienda entonces retirar los dientes impactados para prevenir la ocurrencia de quistes mayores y tumores.

Dentigerous cyst is a casual clinical finding associated with an alteration on the eruption of canine, premolares and third molars. Its diagnostics is bassed on routinare periapical and panoramic Rx examinations. A space folicular bigger than 3 mm around the crown of a tooth is a reasonable approach to diagnose the lesion like cyst dentígerous. Dentígerous cyst is considered the second more frecuent maxilary odontogenic cyst and represent 24 of the jaw cysts, its biggest incidence it is presented between the second and third decade of the life and is characterized to be asymptomatic, for the expansion and loss of the cortical wall even producing facial asymmetries, radicular reabsorptions of contiguous teeth, pain, parestesia, gingival hiperplasy, infection, fistule and pathological fractures. It is recommended then to retire the impacted teeth to prevent the occurrence of cysts and tumors.
