“…According to other studies on the same topic (36,37), we evaluated the distance between the surgical site and the surrounding anatomical structures, making a virtual root-end resection of 3-mm length. In the majority of cases the apical foramen was located at the level of the MSP or between the two premolars (38,39).…”

“…One recent study reported the need of approximately 4.0 – 4.5 mm of resection when performing surgical endodontics at the level of the premolars, being bucco-lingual size of the roots of at least 3.47 – 3.39 mm in the region of MFPs and 3.36 – 3.44 mm in the region of MSPs and a buccal bone width of 0.85 – 0.88 mm in the region of MFPs and of 1.17 – 1.30 mm in the region of MSPs (37). In our study we measured the distance between the center of the canal or the mid-point between two canals were present and the buccal external plate; due to this reason the results could not be compared to those from the study by Zahedi and coworkers (37). However, we found that the midpoint of the canal could be found approximately between, on average, 3 and 4 mm from the buccal plate, taking in consideration a significant variability.…”

Surgically-oriented anatomical study of mandibular premolars: A CBCT study

Background: The knowledge of root canal anatomy and of the anatomical relationship should be considered mandatory when planning surgical endodontics. The aim of the study was to investigate the anatomical features of mandibular premolars, evaluating their relationship with mental nerve. Material and Methods: CBCT scans were evaluated recording the number of roots, root canal configuration and the relationship with mental nerve of 100 mandibular premolars. After simulating a resection of 3 mm of the root, the shape and the number of canals, and the distance to the buccal and lingual bone plate and to the mental foramen was evaluated. Results: The one root-one canal configuration was the most common configuration. The mental foramen was located at the level of MSPs in 40% cases, and it was between MSP and MFP in 46% of cases. The distance between the apex and the vestibular plate was lower than the distance to the lingual one. Conclusions: We found a significant heterogeneity in the anatomy of mandibular premolars. CBCT could be considered important when planning surgical endodontics in this region.

“…When performing any kind of surgical procedure, a surgeon needs to be familiar with the possible variations in the anatomical configurations of both the mandibular canal and inferior alveolar nerve (IAN) [1][2][3]. This is particularly the case when performing root resections, removing wisdom teeth or harvesting autologous bone grafts.…”

Vestibular bone thickness of the mandible in relation to the mandibular canal—a retrospective CBCT-based study

et al. 2019

View full text Add to dashboard Cite

Background: The aim of this study was to assess vestibular bone thickness of the mandible in relation to the mandibular canal and position of the mental foramen in relation to the neighbouring teeth. Measurements were performed on radiographic cone-beam computed tomography (CBCT) images. Methods: This retrospective study analysed 314 CBCTs, having been taken at the Clinic of Cranio-Maxillofacial and

“…En relación a la distancia, el FM se localizó a 5,0 mm en promedio de la raíz más cercana del diente adyacente (Von Arx et al). Otro estudio realizado en población iraní se encontró que la distancia más cercana entre el FM y los ápices de los dientes premolares fue en el sitio de los segundos premolares con un valor medio de 4,32 mm en el lado izquierdo y 4,23 mm derecho (Zahedi et al, 2018).…”

RESUMEN: La ubicación del foramen mentoniano (FM) varía desde el canino hasta el primer molar. La confirmación de la ubicación del FM es fundamental para evitar lesiones nerviosas durante procedimientos odontológicos. La distancia del FM al diente adyacente se puede evaluar mediante tomografía computarizada cone beam (CBCT) de forma segura y precisa. El objetivo fue determinar la distancia promedio entre la cortical superior del FM y el ápice dentario más cercano. Se realizó un estudio descriptivo que midió la distancia en milímetros (mm) desde FM al ápice dentario más cercano de 99 exploraciones CBCT. La medición se realizó en un corte que intercepta el FM y el ápice adyacente. Se evaluaron un total de 99 casos (72 mujeres/ 27 hombres), con una edad promedio de 34,7 años, (rango de 18-73 años). La distancia promedio se ubicó a 3,22 mm del ápice dentario más cercano al FM, la distancia mínima encontrada fue de 0,81 mm y la máxima de 6,99 mm. Se relaciona con el segundo premolar en un 79 % de los casos, y primer premolar en un 17 %. El FM se ubica cercano a la zona de premolares, su localización puede variar en relación a los ápices de estos dientes. Este estudio confirma la importancia de ser cautelosos durante los tratamientos endodónticos y/o quirúrgicos, para prevenir lesiones nerviosas en relación a esta estructura anatómica.
