Materials and methods: Mixed populations of 50 human first and second incisors were mounted in acrylic dento-form blocks. Conventional access cavities were completed without operation microscope, while attempting to locate and subsequently negotiate the second canals. The teeth in which second canal was not located or could not be negotiated were then submitted under Operating Microscope. The r...

Introduction: Panoramic view as a routine dental radiograph has an important role in diagnosis of other facial abnormalities accompanied with dento- alveolar structures. In this case presentation, we discuss this subject and also the efficacy of cone-beam computed tomography in localization of foreign body in complex anatomy of nasal cavity.

A mother and son are reported with chronic dacrocystitis, cup shaped ears, hearing loss, abnormal teeth, and poor formation of saliva and tears. They are similar to previously reported cases of lacrimo-auriculo-dento-digital (LADD) syndrome. The variability of expression of this autosomal dominant syndrome is discussed, and it is suggested that poor saliva and tear formation be added to the phe...
