Bicipital tenosynovitis  is tendinitis or inflammation of the tendon and sheath lining of the biceps muscle. It is often the result of many years of small tears or other degenerative changes in the tendon first manifesting in middle age, but can be due to a sudden injury. Calcification of the tendon, and osteophytes ("bone spurs") in the intertubercular groove  can be apparent on x-rays. The condition (which can also occur in dogs)  is commonly treated with physical therapy and cortisone

Although examination may reveal a fissure on the surface of anterior tooth, radiographic examination is the way. On a periapical radiograph, the invagination lesion will appear as a radiolucent pocket. It is usually seen beneath the cingulum or incisal edge. Larger lesions can appear as fissures. A radio-opaque could be shown. Pulp may be involved and the root canal could have complex anatomy. Two periapical radiographs are often required to make sure that it is not a masked lesion. Cone beam computed tomography (CBCT) is useful in diagnosing DI. It provides clinicians a detailed 3D image and could aid treatment planning. Feasibility of root canal treatment or apical surgery or other procedures could be assessed. Oehlers classification
Class I - Partial invagination. It is limited to the crown of tooth. The lesion does not extend pass the cementoenamel junction (CEJ) or the pulp. Class II - Partial invagination. It extends beyond the crown and CEJ. Pulp may be involved but remain within the root anatomy. There is no communication of the lesion with periodontal ligament (PDL). Class IIIa - Complete invagination. It extends through root and communicates with PDL. It usually does not involve the pulp but can cause anatomical malformation. Class IIIb - Complete invagination. It extends through the root and communicates with PDL through apical foramen. Pulpal anatomy may not be directly involved but can cause disruption to the dental anatomy.
