| Sumario: | The aim of this study was to present a case report through which to demonstrate cone beam computed tomography advantages in impacted mandibular third molars presurgical study. A case of 47-year-old man with a semi/impacted mandibular third molar for surgical removal was reported. Cone beam computed tomography study was made with Promax-3D plus unit. Obteined images were observed and analized by Romexis software 4.4.0.R. In obliques views, third molar presence in very deep and lingual position was verified. Inferior alveolar canal was visualized as a hypodense ovoidal region surrounded by a continuous hyperdense halo and separated from root tooth by 2.80 mm. 3D reconstruction allowed to visualize an intimate contiguous relationship with mylohyoid canal. Impacted mandibular third molar extraction is a commonly performed procedure in dental practice thereby dento-maxillo-facial surgeon must analyze all anatomical details of radiological images. In complex cases, specific studies such as CBCT, which turned out to be the gold standard for pre-surgical diagnosis and planning, should be requested and thus avoid complications that can occur in these surgeries. New and current evidence-based recommendations advocate that cone beam computed tomography study should be performed only when 2D radiological techniques do not provide surgeon with sufficient and accurate information and not as a routine protocol before mandibular third molars surgical removal. |
