The Risk Factors that Can Increase Possibility of Mandibular Canal Wall Damage in Adult: A Cone-Beam Computed Tomography (CBCT) Study in a Chinese Population

Abstract: BackgroundThe objective of this study was to analyze the factors that can increase the possibility of mandibular canal (MC) defect in Chinese people, to evaluate the risk of nerve impairment, and to choose the proper operative method to reduce the risk of mandibular alveolar nerve injury during the extraction of mandibular third molar (MTM).Material/MethodsA total of 954 patients (1,304 MTMs) who underwent orthopantomography (OPG) and cone-beam computed tomography (CBCT) between July 2014 and December 2014 wer… Show more

“…Regardless of the complexity of the extraction, literature shows a wide range in surgery risk varying between 0.8% and 8.4%. 2,16 In 2006, Jeries analysed the occurrence of neurological impairment during lower mandibular third molar surgical in a prospective study with a comparably high number of patients (1087 cases). Patients in this study only underwent two-dimensional imaging in form of an OPT.…”

“…Apesar das indicações, as cirurgias de terceiros molares têm numerosas complicações, nas quais o deslocamento da raiz do dente ou do próprio dente são uma das mais perigosas 6 , e há alguns casos na literatura sobre essas ocorrências 12,13 . Outra complicação que pode ocorrer é a perfuração do seio maxilar, no caso dos terceiros molares superiores.…”

“…Isso se deve ao fato de a radiografia panorâmica ser observada em apenas duas dimensões 5,7 . Recentemente, a TCFC tem sido amplamente utilizada no trabalho clínico devido à sua capacidade tridimensional 5,6,7 e torna-se o exame complementar ideal para avaliar a estreita relação entre os terceiros molares e o NAI 10 . Com o auxílio da TCFC, pode-se obter uma relação precisa do canal alveolar inferior e os ápices das raízes do dente, o que não pode ser feito por métodos radiográficos convencionais 6 .…”
