Diagnostic Accuracy of Ultrasonography for the Assessment of Maxillofacial Fractures: A Meta-analysis.

Objective: To evaluate the pooled sensitivity and specificity of ultrasonography (USG) in maxillofacial fractures.

Materials And Methods: A systematic search was performed in five databases (PubMed, Scopus, CINAHL, Web of Science, Dentistry and Oral Sciences Source) from inception to September 12, 2020. Studies that reported or from which sensitivity and specificity can be calculated and studies published in the English language were included.

Salivary MMP-9 as a Biomarker for the Diagnosis of Oral Potentially Malignant Disorders and Oral Squamous Cell Carcinoma.

Objective: To compare the salivary MMP - 9 concentration among subjects with oral squamous cell carcinoma (OSCC), oral potentially malignant disorders (OPMD), tobacco users, and control groups.

Materials And Methods: A total of 88 subjects were enrolled and divided into four study groups viz., OSCC (n=24), OPMD (n=20), tobacco habits (n=22), and healthy controls (n=22).
