ABSTRACT
Introduction: The inferior dental nerve is an anatomical structure of the mandible which presents variations such as the anterior loop, both structures are related to iatrogenies with treatments such as oral surgeries, bone regenerations and implants. The aim of the present study is to evaluate the characteristics of the anterior loop and the mental foramen using cone beam computed tomography (CBCT) in patients of the Graduate Periodontics Program, School of Dentistry, Universidad Autónoma de Nuevo León.
Material and methods: 110 CBCT were analyzed of which 61 entered the study fulfilling the inclusion criteria, cross sections were made using the On Demand
® software to identify and measure the anterior loop and locate the position of the mental foramen both sides separating our groups by gender.
Results:The prevalence of the anterior loop was 32.8% of 61 CBCT that were analyzed, it was found more commonly in men and bilaterally, and when it was unilateral only found on the right side, the average length was 6 ± 1 mm. The mental hole was found in greater percentage apical to the second lower premolar with an average diameter of 3.5 ± 0.5 mm, moving away from the root of the adjacent tooth by an average of 6 ± 1 mm and from the edge of the mandible 12.5 ± 0.5 mm.
Conclusion: It is very important to locate these anatomical structures during treatment planning and avoid complications during and after the surgical act.
