چکیده

INTRODUCTION Panoramic imaging is a technique for producing a tomographic image of the facial structures, maxillary, mandibular dental arches and their supporting structures [1]. The primary advantage of panoramic imaging is the broad coverage of the facial bones and teeth and the most common demerit is that of the resolution. Image interpretation in an OPG demands a systematic approach and a thorough understanding of the appearances of the normal anatomic structures on the image. Recognizing normal anatomic structures on panoramic radiographs is challenging because of the complex anatomy of the midfacial region [2]. The maxillary sinuses are usually well visualized on panoramic images; even though not all borders are clearly demarcated. Normally medial wall of the maxillary sinus extends anteriorly till the maxillary first premolar (figure 1) and roots of the central and lateral incisor teeth are not in close proximity to the maxillary sinus [3] but we report a case of a healthy individual who underwent radiographic examination for orthodontic purpose, which revealed the medial wall of the maxillary sinus crossing the midline and extending till the central incisor on the opposite side.
