Resumo: | Objective: This study aims to establish the anatomical relationship between the mandibular canal and the third molars, based on analysis by Cone Beam Computed Tomography. Methodology: Computed Tomography analysis of 67 third molars was performed using Blue Sky Plan 4 virtual planning software. The anatomical dispositions of the third molars and mandibular canal were evaluated, as well as the factors that favor the contact between these structures. Result: There was a prevalence of 76.1% for biradicular third molars, 52.2% for class 1 and 71.6% class A. Vertical and mesioangulated teeth had a higher prevalence, with 38.8% and 35.8% respectively. Sicher and Tandler's classification presented 41.8% of the canals as type I, while in the buccal-lingual positioning, 89.5% of the canals were located through the buccal. 44.8% of the teeth had contact with the canal and the factors with statistical significance were: female gender (p = 0.019), number of roots (p = 0.019), class 3 (p = 0.004) and C (p = 0.012) teeth and lingual positioning of the mandibular canal (p = 0.016). About the anatomical delimitations, the mean diameter of the canal was 3.14 mm and the distances related to the dental roots, lingual, buccal and inferior cortical bony were 2.77, 3.53, 4.56 and 8.32 milimeters, respectively. Conclusion: Therefore, the assessment of third molars by computed tomography is essential during preoperative planning, as it identifies anatomical relationships that favor contact between the tooth and the mandibular canal and helps to reduce the incidence of sensorineural disorders. |

Metodología: El análisis de Tomografía Computarizada de 67 terceros molares se realizó mediante el software de planificación virtual Blue Sky Plan 4. Se evaluó la disposición anatómica de los terceros molares y del canal mandibular, así como los factores que favorecen el contacto entre ellos. Resultado: hubo prevalencia en 76,1% para terceros molares birradiculares, 52,2% para clase 1 y 71,6% clase A. Hubo mayor prevalencia de dientes verticales y mesioangulados, con 38,8% y 35,8% respectivamente. Clasificación de Sicher y Tandler presentó 41,8% de los canales como tipo I, mientras que en posicionamiento vestibulo-lingual, 89,5% de los canales se ubicaron por vestibular. 44.8% de los dientes tuvieron contacto con canal y los factores que mostraron significancia estadística fueron: género femenino (p=0.019), número de raíces (p=0.019), dientes clase 3 (p=0.004) y C (p=0.012) y posicionamiento lingual del canal mandibular (p=0,016). En cuanto las delimitaciones anatómicas, el diámetro medio del conducto fue de 3,14 mm y las distancias relacionadas con las raíces dentales y huesos corticales, lingual, vestibular y inferior fueron de 2,77, 3,53, 4,56 y 8,32 mm, respectivamente. Conclusión: Por consiguiente, la valoración de terceros molares mediante tomografía computarizada es fundamental durante la planificación preoperatoria, porque identifica relaciones anatómicas que favorecen el contacto entre diente y el canal mandibular y ayuda a reducir la incidencia de trastornos neurosensoriales.Objetivo: Esse estudo visa estabelecer a relação anatômica entre o canal mandibular e os terceiros molares, a partir de análise por Tomografias Computadorizadas Cone Beam. Metodologia: Foi realizada análise de Tomografias Computadorizadas de 67 terceiros molares em software de planejamento virtual Blue Sky Plan 4. Foram avaliadas as disposições anatômicas dos terceiros molares e do canal mandibular, bem como os fatores que favorecem o contato entre essas estruturas. Resultado: Notou-se prevalência de 76,1% para terceiros molares birradiculares, 52,2% para classe 1 e 71,6% classe A. Houve maior prevalência de dentes verticais e mesioangulados, com 38,8% e 35,8% respectivamente. A classificação de Sicher e Tandler apresentou 41,8% dos canais como tipo I, enquanto no posicionamento vestíbulo-lingual, 89,5% dos canais apresentaram-se localizados pela vestibular. 44,8% dos dentes apresentaram contato com o canal e os fatores que apontaram significância estatística foram: gênero feminino (p=0,019), número de raízes (p=0,019), dentes classe 3 (p=0,004) e C (p=0,012) e posicionamento lingual do canal mandibular (p=0,016). Em relação às delimitações anatômicas, o diâmetro médio do canal foi de 3,14 mm e as distâncias relativas às raízes dentárias e corticais ósseas lingual, vestibular e inferior foram de 2,77, 3,53, 4,56 e 8,32 milímetros, respectivamente. Conclusão: Portanto, a avaliação dos terceiros molares por tomografias computadorizadas é essencial durante o planejamento pré-operatório, pois identifica relações anatômicas que favorecem o contato entre dente e o canal mandibular e auxilia na redução da incidência de distúrbios neurossensoriais.Research, Society and Development2021-06-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1565910.33448/rsd-v10i6.15659Research, Society and Development; Vol. 10 No. 6; e55710615659Research, Society and Development; Vol. 10 Núm. 6; e55710615659Research, Society and Development; v. 10 n. 6; e557106156592525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/15659/14398Copyright (c) 2021 Magno Vinícius Silva Batista; Joel Motta Juniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBatista, Magno Vinícius Silva Motta Junior, Joel2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/15659Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:25.902568Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
