Ultrasonography (USG) as an imaging modality in dentistry has been extensively explored in recent years due to several advantages that diagnostic ultrasound provides. Ultrasonography is a technique based on sound waves that acquires images in real time without the use of ionizing radiation. Ultrasonography is used as an imaging modality for diagnosing many maxillofacial diseases and disorders. It is an inexpensive, easy to use and non-invasive technique, thereby eliminating the harmful effects of ionizing radiation. The application of USG in diagnosing cervical lymph node metastasis, oral sub mucous fibrosis, soft tissue calcifications in carotid region, temporomandibular disorders and salivary gland pathology etc. has been explored in recent years. USG has a promising future as a diagnostic imaging aid in all specialties in dentistry. This review will enlighten the diagnostic applications of USG in maxillofacial region.
