Sinusitis maxilar de origen odontogénica: diagnóstico y tratamiento quirúrgico / Maxillary sinusitis of odontogenic origin. surgical diagnosis and treatment

La sinusitis odontogénica afecta la mucosa de los senos maxilares y puede ser causada por la evolución de una lesión en el diente con formación de pus periapical que avanza en el interior de la cavidad sinusal. Se presenta un caso de un paciente con dens in dente en el diente incisivo lateral superior derecho, que sufrió el proceso de caries evolucionando en la región periapical, contaminando la mucosa sinusal de este lado, lo que causó el dolor, abultamiento y el desplazamiento del diente. La cirugía se realizó a través de acceso de Caldwell-Luc para el curetaje de la lesión, lo que indica la presencia en el diagnóstico histopatológico la presencia de quiste abscedado y sinusitis. Después de 18 meses de control, se observó la regeneración ósea y el reposicionamiento alveolar espontáneo de los dientes implicados. Los autores advierten que cíngulos profundos y dens in dente son las enfermedades de los dientes que merecen atención para el diagnóstico y la prevención de los procesos de caries con el fin de evitar complicaciones mayores.

Odontogenic sinusitis affects mucous membrane of the maxillary sinus and can be caused by the evolution of a tooth injury with formation of periapical abscess that advances into the sinus cavity. We present a patient with dens in dente in the upper right lateral incisor tooth, which suffered carious process and periapical abscess, contaminating the sinus mucosa on this side, which caused pain, bulging and tooth displacement. Surgery was performed via a Caldwell-Luc access for curettage of the lesion, indicating the presence in the histopathological diagnosis of radicular cyst abscess and sinusitis. After 18 months of control, alveolar bone regeneration and spontaneous repositioning of teeth involved was observed. The authors warn that cingulum deep in dens in dente are diseases of the tooth that deserve attention for the diagnosis and prevention of carious processes in order to avoid further complications.

Concomitant hypo-hyperdontia with dens invaginatus.

Although developmental anomalies of tooth number are quite common in permanent dentition, concomitant occurrence of hypohyperdontia is a very rare mixed numeric anomalous condition of teeth. Very few cases of this condition have been reported in the English literature. Here we report such a rare case noted in a 26 year-old male dental graduate with no other associated systemic condition or syndrome.

Multi-lobed mesiodens with a palatal talon cusp: a rare case report

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch and the talon cusp is a rare dental developmental anomaly seen on the lingual surface of anterior teeth. This paper presents a rare clinical case of development of talon cusp in a mesiodens with multiple lobes, which interfered with both occlusion and appearance of an 11-year-old patient. During clinical interview, the patient reported difficulty on mastication. Clinical and radiographic examination revealed that a supernumerary tooth with completely formed root was causing an occlusal interference. The supernumerary tooth was diagnosed as multi-lobed mesiodens associated with a palatal talon cusp. The treatment plan consisted in the extraction of the supernumerary tooth followed by orthodontic treatment for diastema closure and tooth alignment.

Mesiodens é um dente supranumerário mais comumente visto no arco maxilar na linha média, e a cúspide em garra (talon cusp) é uma anomalia dental de desenvolvimento rara que ocorre na face lingual de dentes anteriores. Este artigo apresenta um caso clínico raro de desenvolvimento de uma cúspide em garra em um mesiodens multilobulado que causava interferência tanto na oclusão quanto na aparência de um paciente de 11 anos de idade. Durante a entrevista clínica, o paciente relatou dificuldade na mastigação. Exame clínico e radiográfico revelou que um dente supranumerário com raiz completamente formada estava causando interferência oclusal. O dente supranumerário foi diagnosticado como sendo um mesiodens multilobulado associado a uma cúspide em garra palatina. O plano tratamento consistiu na extração do dente supranumerário seguida de tratamento ortodôntico para fechamento de diastema e alinhamento dos dentes.

Nonsurgical treatment of periapical lesion associated with type III dens invaginatus using calcium hydroxide: a case report.

Dens invaginatus is a developmental malformation of teeth, probably resulting from an infolding of the papilla during tooth development. It predisposes the tooth to develop caries and periapical pathosis. Root canal therapy may present many problems because of the complex anatomy of the teeth. The purpose of this case report is to describe the endodontic treatment of an Oehlers type III dens invaginatus that perforated into the apical area. Calcium hydroxide powder mixed with normal saline, was used as an intracanal medicament. This eradicated the pathogenic microorganisms in the invagination and preserved the vitality of the tooth, allowing gutta-percha obturation in the invagination.

Management of two unusual cases of dens invaginatus and talon cusp associated with other dental anomalies.

The management of two unusual cases of dens invaginatus and talon cusp is presented. The first concerns talon cusp in maxillary primary and permanent lateral incisors, a supplemental tooth with dens invaginatus hampering eruption of the permanent incisors. The other present with bizarre crown morphology of a lateral incisor with talon cusp, dens invaginatus and a palatal accessory cusp-like structure. Early diagnosis and management are important to avoid complications.
