“…Assim, de acordo com Kang et al 53 , os principais fatores determinantes do risco de dano e distúrbio neurossensorial ao n. alveolar inferior após extrações de terceiros molares são achados radiográficos, como estreitamento do canal mandibular (19,8%) e escurecimento da raiz (18,9%), grau de impacção óssea, proximidade do dente ao canal mandibular, a técnica cirúrgica de escolha (necessidade de ostectomia revelou maior risco), a exposição do nervo no período intraoperatório e experiência do cirurgião, sendo assim recomendado a TCCB quando estes sinais forem identificados na radiografia panorâmica.…”

Terapia a laser de baixa potência no tratamento de lesões periféricas do nervo trigêmio em Odontologia: revisão de literatura

A parestesia é um distúrbio neurossensorial decorrente de lesão nervosa que ocorre após uma intervenção odontológica e leva à perda de sensibilidade prolongada de uma região específica da face, além de outros sintomas, podendo ser resolvida espontaneamente após alguns dias ou meses, mas dependendo da extensão e tipo de lesão nervosa, este dano pode ser permanente. Com o avanço da tecnologia, os lasers vêm se popularizando na Odontologia, juntamente com os avanços em pesquisas. A terapia de fotobiomodulação com laser de baixa potência tem se mostrado como uma opção favorável ao tratamento de distúrbios neurossensoriais e aceleração do processo de reparo tecidual. Foi realizada uma revisão da literatura, a partir de buscas nas bases de dados do PubMed/MEDLINE, Biblioteca Virtual em Saúde (BVS), The Cochrane Library e Scielo, entre os anos de 2010 a 2020. O presente estudo tem como objetivo analisar a eficácia, a utilização terapêutica, e os mecanismos de ação da terapia a laser de baixa potência (LLLT), como também causas e fatores de risco relacionados aos procedimentos mais comuns de injúria nervosa. As recentes pesquisas envolvendo o uso da terapia de fotobiomodulação evidenciam a capacidade do laser em promover aceleração do processo de reparo tecidual, com fenômenos analgésicos, anti-inflamatórios, cicatrizantes e regenerativos. Embora tenha havido grandes descobertas nos últimos anos, a literatura ainda carece de protocolos e ensaios clínicos sobre o uso do laser, verificando e comprovando seus efeitos sobre lesões nervosas, devendo este ser o foco de pesquisas futuras.

“…Coronectomy is indicated when the lower third molar is in contact with the IAN, so complete removal could injure the nerve (Cervera‐Espert, Perez‐Martinez, Cervera‐Ballester, Penarrocha‐Oltra, & Penarrocha‐Diago, 2016; Kang, Sah, & Fei, 2020). The incidence of IAN injury, one of the most significant complications related to third molar extraction, appears to be lower with coronectomy, as reported in many studies (Cervera‐Espert et al, 2016; Dolanmaz, Yildirim, Isik, Kucuk, & Ozturk, 2009; Hatano et al, 2009; Leung & Cheung, 2009; Martin et al, 2015; O'Riordan, 2004).…”

Comprehensive review of lower third molar management: A guide for improved informed consent

Lower third molar removal is the most commonly performed dental surgical procedure. Nevertheless, it is difficult to ensure that all the informed consent forms given to patients are based on the best evidence as many newer publications could change the conclusions of previous research. Therefore, the goal of this review article is to cover existing meta‐analyses, randomized control trials, and related articles in order to collect data for improved and more current informed consent.

“…The anatomical position of the IAC is very close to the root of the tooth. Iatrogenic injury of inferior alveolar nerves and vessels may occur during root canal treatment, extraction of impacted mandibular third molar (IMTM), and implant treatment due to periapical infection, local anesthesia, overuse of drugs or medical instruments, etc 2,3 . The anatomical position and direction of the IAC should be taken into account for reducing the incidence of neurosensory disturbance during mandibular invasive surgical procedures such as mandibular osteotomies, fracture repair, and orthognathic surgeries 4–6 .…”

Purpose The shape and position of the inferior alveolar canal (IAC) are analyzed to effectively reduce the risk of iatrogenic injury based on cone‐beam computer tomography (CBCT). To assist dental clinicians to make better use of the IAC information, we propose an IAC segmentation method based on CBCT images. Methods In this paper, CBCT images are first preprocessed by the Hounsfield unit values clipping and gray normalization. Secondly, based on the multi‐plane reconstruction (MPR) and curved surface reconstruction, the curved MPR image sets are generated by the smooth dental arch curve with a sampling distance of 1.00 pixels. Then, the K‐means clustering algorithm is used to cluster the texture parameters of the gray level‐gradient co‐occurrence matrix enhanced by the gradient directions to improve the image contrast of the IAC. Finally, the IAC edges are roughly segmented by the 2D line‐tracking method, and smoothed by the fourth‐order polynomial to obtain the final segmentation result. Results Twenty‐one real clinical dental CBCT datasets were used to test the proposed method. The manual segmentation results of two specialized dental clinicians were used as quantitative evaluation criteria. The dice similarity index (DSI), average symmetric surface distance (ASSD), and mean curve distance (MCD) of the left IAC are 0.93 (SD = 0.01), 0.16 mm (SD = 0.05 mm), and 1.59 mm (SD = 0.25 mm), respectively; the DSI, ASSD, and MCD of the right IAC are 0.93 (SD = 0.02), 0.16 mm (SD = 0.05 mm), and 1.60 mm (SD = 0.30 mm), respectively. Conclusions The proposed method provides an effective image enhancement and segmentation solution to analyze the shape and position of the IAC. Experimental results show that the relationships between the IAC and other structures can be accurately reflected in the panoramic images without superimposition and geometric distortion, and the smooth edges of the IAC can be segmented.
