Canalis sinuosus approximation on an impacted maxillary canine: a case report

Objectives: This case report is aimed to report the finding of canalis sinuosus on an impacted maxillary canine using cone beam computed tomography (CBCT) examination. Case Report: A 21-year-old male was referred from orthodontic department to radiology department UNPAD Dental Hospital for CBCT to determine the treatment of malalignment asymptomatic maxillary canine. The case revealed the presence of canalis that was identified as a canalis sinuosus, a branch of the anterior superior alveolar nerve that rarely known by a practitioner, at the apex of impacted right maxillary canine. Conclusion: The information of this anatomical variation is important for professionals due to damage that may be caused during treatment. The use of advanced imaging examination is recommended to acknowledge the individual anatomical variation before determining the proper treatment planning.

Rama del canalis sinuosus imitando una reabsorcion intrarradicular: reporte de caso

El objetivo de este estudio es potenciar la importancia del conocimiento anatómico clínico de las estructuras que conforman el maxilar anterior, particularmente el canalis sinuoso y sus ramas accesorias y como dichas estructuras se presentan en los exámenes imagenológicos complementarios bi y tridimensionales como la radiografía periapical y la Tomografía Computarizada de Haz Cónico (CBCT). Se presenta un caso clínico de superposición de una rama accesoria del canalis sinousus que simula una reabsorción radicular interna. El análisis minucioso de cada caso clínico, junto al uso de las herramientas imagenológicas actuales nos permite establecer diagnósticos clínicos certeros y evitar tratamientos innecesarios.

Evaluation of Location of Canalis Sinuosus in the Maxilla Using Cone Beam Computed Tomography

SummaryBackground/Aim: The aim of this study is to evaluate the prevalence of a canalis sinuosus (CS) in the anterior maxilla.Material and Methods: CBCT images of 673 patients (322 females and 351 males) were examined retrospectively with regard to age, gender, location of CS and relation to impacted canines. The age of the patients ranged from 14 to 82 years; the mean age of the female patients was 43.54 years and that of the males was 45.75 years. IBM SPSS 22 for Windows was used for statistical analysis of the results. Statistical comparisons between two categorical variables were conducted using chi-square tests. Significance was set at (p< 0.05).Results: It was observed that 8.17% of the patients in this study exhibited accessory canals (AC) of CS (n= 55). There was no significant difference in CS prevalence between ages, age groups, and location in our study (p> 0.5). There was significant difference in CS prevalence between the genders (p< 0.5). Conclusions: It is important to take into consideration the presence of AC of the CS during surgical procedures in the anterior maxilla. It was also found that CBCT is more helpful than other techniques in detecting accessory canals in the region of interest.
