Infectious Disease Of Oral Cavity Highlights

• Dental professionals are involved in the diagnosis and treatment of common and rare infections that are either specific to the oral cavity or as a part of generalized or systemic infections or diseases.
• Dentists are responsible for the management of these conditions by developing a promising treatment plan. The selection of appropriate antimicrobials plays a critical role in successful treatment.
