Materials and Methods:In one case the condition was associated with a supernumerary teeth. In the other case the kissing molars were associated with a dentigerous cyst, which disarticulated the two impacted teeth. The third case of kissing molars involved a fibro-osseous lesion in the anterior mandibular region.Result: We are in the opinion that kissing molar cases should be further examined for other lesions of the jaws.

Bilateral TMJ MR images in the sagittal and coronal sections, from 518 patients with TMJ symptoms were evaluated retrospectively. Patients who were diagnosed with IFs were sent for consultation and clarification of the findings. Patient age, gender, IFs, locations, and diseases were classified and noted.  Results: Seventy-eight (15%) patients were diagnosed with 117 IFs. Of them, 43 were diagnosed with a single IF, and 35 were diagnosed with more than one IF. The most frequent locations were paranasal sinuses and mastoid air cells. The most frequent diseases were inflammatory and cystic lesions.  Discussion: While examining TMJ MR images, it is important to check for evidence of IFs or pathologies that may have mimicked signs and symptoms of TMJ disorders.
