Objective: The purpose of this review is to make the reader aware of the biophysical basis for using ultra-sound. The focus will primarily be on the use of ultrasound in Oral & Maxillofacial surgery.
 

Methods: Data were gleaned from a literature search of available medical and dental databases including Research gate, Ovid, Pub-med, Medline, Cochrane and non-medical search engines such as Wikipedia and Google.
 

Result: In the field of Oral & Maxillofacial Surgery, use of ultrasound for therapeutic as well as for diagnostic purposes have been employed for over three decades with modest documentation on its adverse effect. To clearly distinguish the occurrence or absence of mass like lesions in oral & maxillofacial region and to accurately visualize normal and anomalous anatomic structures various imaging modalities

like plain radiography, CT, MRI, and US can be used but among these, US imaging is best because it is easy to use, cost-effective and least invasive.
 

Conclusion: In this present review, we discussed the role and clinical implications of ultrasonography (US) for therapeutic as well as for the diagnosis of various diseases in oral and maxillofacial regions. Today, we are in need of more studies that must emphasis to study the bio-effects of ultrasound in more comprehensive manner and provide reliable method which can be reproducible for better performance of US.
