“…According to studies from the United States (17), Iran (20), China (10), and Brazil (18), the MIC was closer to the buccal cortex than to the lingual cortex during its intraosseous path, and in agreement with the present study. Lim et al (19) reported that MIC deviated lingually from its starting point towards its endpoint in the mandible. Yang et al (13) found that in the canine region, there was a decrease in the distance of the MIC to the lingual cortex.…”

Background: This study evaluated the epidemiological and morphological features of the mandibular incisive canal (MIC) using cone beam computed tomography (CBCT) in a significant sample of subjects in Brazil. Material and Methods: This retrospective, multicenter study assessed 847 CBCT scans performed at four oral imaging centers. The sample comprised CBCT images acquired from dentate individuals who presented at least from tooth 35 to tooth 45 in the anterior mandible region. Data regarding patient sex and age, and MIC linear measurements (length and diameter in mm), anatomical distances (to the alveolar, buccal and lingual cortexes, inferior border of the mandible, and adjacent teeth apexes), and location were obtained. Results: The MIC was more prevalent in women (76.3% [p<0.001]) between the fourth and sixth decades of life (p<0.001). It was present bilaterally (p<0.001) and exhibited a mean length of 7.7 mm (standard deviation [SD]=3.7 mm). Spearman correlation and logistic regression analysis revealed collinearity between age and linear measurements (p<0.05). The mean distances varied from the initial to the final portion of the MIC, respectively, in relation to the buccal cortex (mean=2.6 mm, SD=1.27; mean=3.96 mm; SD=1.43), to lingual cortex (mean=5.13 mm; SD=1.7; mean=4.61 mm, SD = 1.65), and to the inferior mandibular border (mean = 9.32 mm, SD=1.92; mean=8.76 mm, SD=2.07 mm). The difference in the proximity of the MIC to the apex of the inferior lateral incisor was statistically significant (p<0.05).

“…Se ha descrito la cercanía del MIC con la cortical vestibular y lingual, donde Lim et al (2019) describe que a nivel inicial el canal incisivo mandibular se encuentra más cercano a la cortical vestibular y a nivel final y medio más cercano a la cortical lingual, sin embargo, a nivel general el curso del MIC se inclinó más hacia el margen vestibular de la mandíbula. Pires et al, en cambio, describe que el MIC se encontraría más cerca de la cortical vestibular independientemente de su origen o ubicación terminal, Kong et al también describe una cercanía del canal con el margen vestibular y margen inferior mandibular al igual que Vu et al (2015) en su estudio de disección de cadáveres.…”

“…El MIC contiene al nervio incisivo mandibular, el cual proporciona inervación a los dientes antero inferiores y a la mucosa circundante. El diámetro del canal mandibular disminuye de lateral a medial (Pietrokovski et al, 2007), al igual que su corticalización ósea (Kong et al), produciendo que el MIC sea omitido.…”

RESUMEN:El canal incisivo mandibular (MIC) es un canal neural que contiene una de las ramas inferiores del nervio alveolar inferior, llamado nervio incisivo mandibular, que puede resultar dañado durante intervenciones quirúrgicas y causar complicaciones postoperatorias. Estudio descriptivo de corte transversal. Se identificó el MIC en la imagen transversal del canino en 83 hemiarcadas. Se registró edad, sexo, hemiarcada, longitudes desde reborde alveolar vestibular de canino a MIC, cortical lingual y vestibular de canino a MIC, base mandibular de canino a MIC y ubicación del MIC (tercio lingual, medio, vestibular). Medidas se registraron en milímetros. Se aplicó test T-student para muestras independientes para variables de longitud y Chi-cuadrado para ubicación espacial del MIC, en relación con grupo etario y sexo. Se evaluó el MIC en todas las muestras (100 %). El MIC fue encontrado mayormente en el tercio medio mandibular (p <0,05). La media desde el MIC a la cortical lingual es de 5,25 mm ± 1,42 mm (derecho) y 5,24 mm ± 1,18 mm (izquierdo). La media desde el MIC a la cortical vestibular fue de 4,42 mm ± 1,29 mm (derecho) y 4,53 mm ± 1,24mm (izquierdo). La media entre centro del canal y reborde alveolar vestibular fue 18,89 mm ± 2,68mm (derecho) y 18,20 mm ± 3,06 mm (izquierdo), media desde centro del MIC al margen basal fue de 9,77 mm ± 1,93 (derecho) y 10,12 mm ± 1,92 mm (izquierdo). Se encontró mayor distribución del MIC en el tercio medio mandibular. Se identificó el MIC en el 100 % de las muestras a través de CBCT por lo que su uso como examen complementario debe ser considerado al planificar cirugías en el sector anterior mandibular.

“…In clinical practice, the most commonly used radiological technique for morphological assessment of the MIC is cone-beam computed tomography (CBCT) [ 3 , 4 , 5 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ] ( Figure 1 ).…”

Detection Rate and Variability in Measurement of Mandibular Incisive Canal on Cone-Beam Computed Tomography: A Study of 220 Dentate Hemi-Mandibles from Italy

The mandibular incisive canal (MIC) is a small bony channel located in the interforaminal region; it represents the anterior continuation of the mandibular canal. Cone-beam computed tomography (CBCT) is the most commonly utilized radiological technique for assessing the MIC. The main purpose of this study was to evaluate the detectability and variability in measurements of the MIC on CBCT. A total of 220 dentate hemi-mandibles were retrospectively selected for this study. For each hemi-mandible, the detectability, diameter, and distance of the MIC from anatomical landmarks (cortical plates and tooth apices) were evaluated in consensus by two observers. The analysis was performed at four different levels (first premolar, canine, lateral incisor, and central incisor) and was repeated after one month. The variability of MIC measurements was expressed as the coefficient of repeatability (CR), obtained from the Bland–Altman analysis. The MIC detection rate reduced from the first premolar to the central incisor (from 82.3% to 0.5%). The CR of MIC measurements (diameter and distances from anatomical landmarks) was ≤0.74 mm. Although the MIC is difficult to detect in a non-negligible percentage of cases, the limited variability in measurements confirms that CBCT is an effective technique for the assessment of the MIC.
