Quiste óseo solitario / No disponible

INTRODUCCIÓN: El quiste óseo solitario representa el 1% de todos los quistes maxilares. Es una lesión ósea benigna que aparece de forma fortuita en una radiografía de control en la primera/segunda década de la vida, aunque la lesión carezca de trascendencia en la vida del paciente requiere de abordaje quirúrgico para confirmar el diagnóstico. CASO CLÍNICO: Se presenta un caso clínico de una paciente mujer de 11 años de edad y raza negra, remitida al Servicio de Cirugía Bucal del Hospital Virgen de la Paloma tras observarse imagen radiotransparente apical a nivel de 43 y 44. Una vez realizada la exploración clínica y radiológica se propone cirugía exploratoria ante diagnóstico de presunción de quiste óseo solitario. Bajo anestesia local se procedió al abordaje quirúrgico observándose cavidad vacía en maxilar inferior sin contenido alguno, legrándose profusamente las paredes de la cavidad e introduciendo plasma rico en plaquetas obtenido previamente de la paciente. CONCLUSIONES: La cirugía exploratoria confirma el diagnóstico de presunción de quiste óseo solitario vacío al no poderse mandar a analizar a anatomía patológica

Tratamiento quirúrgico de quistes dentígeros asociados a terceros molares: presentación de dos casos clínicos y revisión de la literatura / Surgical treatment of dentigerous cysts associated to third molars: two case reports and a literature review

Introducción. El quiste dentígero es un quiste odontógeno del desarrollo de origen epitelial, siendo el más común después del radicular. Generalmente se asocia con la corona de dientes permanentes impactados o no erupcionados y su aparición es más frecuente en varones durante la segunda década de la vida. Los dientes que suelen verse más afectados son los terceros molares mandibulares, seguido de los caninos maxilares. A causa de su curso asintomático, el diagnóstico suele realizarse por hallazgo casual en radiografías panorámicas rutinarias. Para el diagnóstico definitivo es indispensable la realización de la anatomía patológica. Caso clínico. Se presenta el caso clínico de dos mujeres de 60 y 42 años de edad, sin antecedentes médicos de interés, remitidas al servicio de Cirugía Bucal del hospital Virgen de la Paloma, presentando una imagen radiográfica radiotransparente asociada a la corona del tercer molar inferior izquierdo sin sintomatología asociada. Tras realizar la extracción quirúrgica de los cordales afectados y la lesión quística asociada, se obtiene el diagnóstico definitivo mediante la anatomía patológica, posteriormente se realizan controles clínicos y radiográficos de la zona. Conclusiones. El quiste dentígero representa el segundo quiste odontógeno más frecuente después del quiste radicular en terceros molares retenidos. Es importante el examen radiográfico periódico de terceros molares incluidos para el diagnóstico y tratamiento de esta entidad patológica (AU)

Introduction. A dentigerous cyst or follicular cyst is defined as a developmental odontogenic cyst of an epitelial origin which represents the second most common entity after the radicular cyst. Generally it is associated with the crown of a permanent unerupted tooth (or semi-erupted) and it tends to be more frequent in males during the second decade of life. The most common location of dentigerous cyst are mandibular third molars followed by the maxillary canines. Due to its asymptomatic behaviour, the diagnosis is reached by routine panoramic radiography, however, the anatomopathologic analysis will define its nature. Case Report. A case report of a 42 and 60 year old females with no medical history of interest, referred to the Oral Surgery Service of the hospital Virgen de la Paloma with a radiotransparent images surrounding the crown of the lower left third molar without associated symptoms. After the extraction of the teeth, cystic lessions are sent for anatomopathological study, which confirm the presumption diagnosis, dentigerous cyst. Patients carried out posterior follow ups sho-wing a positive healing of the bone around the surgical area. Conclusions. Dentigerous cyst represents the second most frequent odontogenic cyst after the radicular cyst at mandibular third lower molars. It is essential to monitor retained mandibular lower third molars for the incipient approach of the pathology (AU)

Exodoncia en pacientes geriátricos con bifosfonatos / Extraction in geriatric patients with phosphonates

En el paciente geriátrico, resulta común la presencia de enfermedades sistémicas, lo que conlleva a un consumo de diferentes fármacos para el tratamiento de las mismas. Uno de los más frecuentes son los bifosfonatos. Por lo general, los bifosfonatos son fármacos bien tolerados si se administran correctamente, aunque en los últimos años también se han descrito diferentes efectos adversos asociados a su consumo, siendo la osteonecrosis maxilar uno de los más importantes. Desde entonces son numerosos los casos publicados en los cuales se afirma que los procedimientos quirúrgicos menores como las exodoncias podrían ser uno de los factores desencadenantes. En el caso de los bifosfonatos intravenosos, dado que el riesgo es mucho mayor, se sugiere evitar en lo posible los tratamientos quirúrgicos orales como las extracciones mientras que en los tratamientos con bifosfonatos orales no se puede contraindicar dichos tratamientos de esa manera tan categórica Ante esta situación resulta evidente la necesidad de establecer unos protocolos definitivos encaminados a la prevención y tratamiento de esta posible complicación que pudiese acontecer (AU)

In geriatric patients is common the presence of systemic diseases, leading to a use of various drugs for the treatment thereof. One of the most common are the bisphosphonates. In general, bisphosphonates are well tolerated drugs if properly managed, although in recent years have also been described different adverse effects associated with its consumption, with the maxillary osteonecrosis one of the most important. Since then are numerous reported cases in which it is stated that minor surgical procedures such as extractions could be one of the triggers. In the case of intravenous bisphosphonates, since the risk is much higher, it is suggested to avoid possible oral surgical treatments like extractions while on treatment with oral bisphosphonates may not contraindicate such treatments that so categorically. In this situation the need to establish a definitive protocols aimed at the prevention and treatment of this possible complication that could happen is obvious (AU)

Epidemiology and treatment of adenoid cystic carcinoma of the minorsalivary glands: A meta-analytic study

Objectives: To evaluate the epidemiological aspects of adenoid cystic carcinoma (ACC) and to evaluate the differenttherapeutic possibilities as well as the percentage of survival.Study Design: A retrospective, meta-analytic, observational study was carried out by selecting a total of 13 articles,which provided a sample size of 263 cases of patients who had been diagnosed with ACC in the minorsalivary glands.Results: ACC was found to be more common among women (56.5%) and the average age at diagnosis was 55.26years old. The primary location of the tumor was in the palate in 57% of the cases, the predominant pattern beingcribiform. The treatment of choice was therapy combined with surgery and radiotherapy in 62.7% of the subjects.The overall survival rate was 70.76% and 56.76%, at 5 and 10 years respectively.Conclusions: Early detection of adenoid cystic carcinoma is necessary in order to enable making an earlier prognosis and thus enable a better quality of life for the patient (AU)

Immediate post-extraction implants subject to immediate loading: a meta-analytic study.

UNLABELLED: Since Brånemark first started developing its implant system, there has been a continuous and significant evolution in oral implantology through experimental and clinical research, and many of the concepts that were once considered valid have now become the subject of debate. The insertion of the implant immediately after extraction of the tooth to be substituted has now become the implant treatment of choice and is associated with preserving the bone structure and the gingival architecture, as well as with reducing the treatment time, which ultimately benefits the patient. OBJECTIVE: To evaluate the success rate of the immediate post-extraction implants (IPI) subject to immediate loading. STUDY DESIGN: A meta-analytic study was carried out on 659 immediate post-extraction implants obtained from a bibliographic review of 25 articles published within the last 9 years. RESULTS: We obtained a sample of 322 patients who had been treated with a total of 659 implants placed immediately following extraction. The mean age of the patients was 51 years old. A total of 441 implants were inserted in the maxilla, 152 in the mandible and 64 were placed in an unspecified location. The survival rate ranged between 85% and 100%. CONCLUSIONS: Immediate post-extraction implant treatment is an implant alternative with a survival rate similar to that of the conventional technique for implant placement and enables preserving both the bone structure and gingival architecture, as well as providing immediate functional loading, thus improving the quality of the treatment as far as the patient is concerned.

Fusión de un tercer molar mandibular con un cuarto molar supernumerario / Fusion of mandibular third molar with supernumerary fourth molar

La fusión dental es la unión de dos gérmenes dentales normalmenteseparados, mientras que la geminación se define como el intentode división de un único germen dental.La fusión y geminación de molares es poco frecuente en la dentición permanente.Describimos un caso clínico de un tercer molar inferior derecho fusionadoa un cuarto molar supernumerario en un paciente varón de 36 años queha presentado repetidos episodios de pericoronaritis. Tras el estudio radiológicose realiza la exodoncia del cordal semiincluido bajo anestesia local.Llevamos a cabo una revisión bibliográfica al respecto(AU)

Dental fusion is the union of two tooth buds that normallyare separated, while gemination is defined as an attempt by a singletooth bud to divide.The fusion and gemination of molars is uncommon in permanentteeth.We report a clinical case of a right lower third molar fused to asupernumerary fourth molar in a 36-year-old male patient withrepeated episodes of inflammation. After the radiologic study, thesemi-impacted third molar was extracted under local anesthesia.The literature was reviewed(AU)
