Intramandibular salivary inclusions and ectopia concern the main salivary glands. The most common takes the form of a regular well-defined lacunar appearance situated at the mandibular angle or molar region. This asymptomatic inclusions is in fact only the imprint of a lobule of the sub-mandibular gland on the mandible. More rarely, the parotid gland and sublingual gland may also be responsible for a lacunar radiological appearance in the mandible. By contrast, a few ectopic glandular lobules of the sublingual may be completely induced at the site of the mandibular symphsis. Salivary inclusions and ectopia thus result from two different aerio-pathogenic mechanisms.
下颌骨内唾液腺包涵体和异位涉及主要唾液腺。最常见的表现为位于下颌角或磨牙区的规则、边界清晰的腔隙状外观。这种无症状的包涵体实际上只是下颌下腺小叶在下颌骨上的印记。更罕见的是，腮腺和舌下腺也可能导致下颌骨出现腔隙状放射学表现。相比之下，舌下腺的一些异位腺小叶可能在下颌联合处完全形成。因此，唾液腺包涵体和异位是由两种不同的气源性致病机制引起的。
