Morbilidad de la extracción de los terceros molares en pacientes entre los 12 y 18 años de edad / Morbidity of third molar extraction in patients between 12 and 18 years of age

Objetivo: El propósito de este estudio fue analizar la incidenciade complicaciones después de la extracción quirúrgica de losterceros molares en pacientes de 12 a 18 años de edad.Pacientes y método: Se realizó un estudio retrospectivo de390 extracciones quirúgicas de terceros molares superiores einferiores en 173 pacientes en edades comprendidas entre los12 y 18 años de edad, intervenidos bajo anestesia locorregionalen el año 2000 en el Máster de Cirugía Bucal e ImplantologíaBucofacial de la Universidad de Barcelona.Los pacientes fueron divididos en tres grupos (A: 12-14 años,B:15-16 años, C: 17-18 años). Se registró la edad y el sexo delpaciente, el motivo de la extracción, el grado de desarrollo dentario,la posición, la angulación y la inclusión del tercer molar.Finalmente se valoró la asociación entre dichas variables y laaparición de complicaciones postoperatorias.Resultados: La mayoría de los pacientes intervenidos fuerondel sexo femenino (66,9%), y el grupo de edad en la que serealizó el mayor número de extracciones (62,8%) fue en elgrupo C (17-18 años). El principal motivo de extracción fuela indicación por parte del ortodoncista (40,5%), seguido porla indicación profiláctica (39,5%). La presencia de clínica fueel motivo de extracción en un 20% de los casos. Se observóuna incidencia del 15,6% de complicaciones postoperatoriastras la extracción de 390 terceros molares. En el grupo A elriesgo de complicaciones fue de 17,4%, en el grupo B de 19% y en el grupo C de 13,7%. Todas las complicaciones fueronreversibles y de corta duración como el dolor y la inflamaciónpersistente, la infección, el trismo y la equimosis. Se presentóun caso de parestesia del nervio dentario inferior y un caso deparestesia del nervio lingual que remitieron a los 2 meses y almes respectivamente.Conclusiones: este estudio demuestra que no hay diferenciassignificativas en las complicaciones observadas entre los tresgrupos de edad, y por lo general, éstas son leves y reversibles. Seobservó una mayor tendencia de complicaciones en las mujeresy el porcentaje de complicaciones aumenta cuanto menor es elespacio disponible para la erupción

Objective: An analysis is made of the incidence of complicationsfollowing third molar surgical extraction in patients between 12and 18 years of age.Patients and method: A retrospective study was conducted of390 surgical extractions of upper and lower third molars in 173patients operated upon under locoregional anesthesia during theyear 2000 in the Master in Oral Surgery and Implantology ofBarcelona University Dental School (Spain).The patients were divided into three age groups (A: 12-14 years,B: 15-16 years, C: 17-18 years). The reason for extraction, thedegree of dental development, and third molar position, angleand impaction were recorded. Finally, the association of thesevariables to the appearance of postoperative complications wasanalyzed.Results: Most patients were females (66,9%), and the age groupin which most extractions were carried out (62,8%) correspondedto Group C (17-18 years). The main reason for extraction wasorthodontist indication (40,5%), closely followed by prophylaxis(39,5%). The existence of clinical manifestations was an indicationfor extraction in 20% of cases. The postoperative complicationsrate after the extraction of the global 390 molars was15,6%. In Groups A, B and C the complication risks were 17,4%,19% and 13,7%, respectively. All complications were reversibleand of short duration. One case each of inferior alveolar nerveparesthesia and lingual nerve paresthesia was recorded, which subsided after one and two months, respectively.Conclusions: There were no significant differences in complicationsbetween the three age groups. An increased tendencytowards complications was observed in females, and the percentageof postoperative problems increased
