Impacted third molars tend to pose certain problems varying from pain, repeated pericoronitis, bone loss with adjacent teeth, etc. The surgical removal of impacted teeth requires appropriate planning to avoid complications. Cone beam computed tomography (CBCT) is an important radiographic tool that facilitates appropriate treatment planning. This retrospective analysis of the existing orthopantomographs (OPG) and CBCT images of third molars was conducted to assess the topographic relationship between impacted mandibular third molar and the inferior alveolar nerve (IAN) canal. In this study, 124 OPGs and CBCT images were used to assess the type of impactions and evaluate the relationship of impacted teeth with the IAN. Mesioangular impaction was the most commonly observed type of impaction followed by vertical, horizontal, and distoangular impactions. The most commonly observed relationship was mandibular canal running apically or buccally with respect to the impacted tooth but without being in contact with it. The classification utilizing the topographic relationship of the impacted mandibular third molar with the IAN canal gives a clear position of the IAN to the impacted teeth. The use of digital volume tomography (DVT) for radiographic assessment reveals the relationship in axial, coronal, and sagittal dimensions, which facilitates appropriate treatment planning to avoid post-operative complications.

Neoplasms that arise in the salivary glands are relatively rare, yet they represent a wide variety of both benign and malignant histologic subtypes. Approximately 70% of the salivary gland tumors affect parotid gland with the submandibular gland being affected in 5-10% of the cases, sublingual gland in 1% and minor glands in 5-15% of the cases. Submandibular gland tumors are relatively rare and very few studies have been reported in the literature that is exclusively conducted on tumors affecting submandibular gland. In this paper, we describe a case of pleomorphic adenoma affecting submandibular gland with brief review of current literature on submandibular gland tumors.
