Oral and Maxillofacial Surgery, Medicine, and Pathology for the Clinician

Single volume reference bringing together surgery, medicine, and pathology to provide relevant clinical information

Oral and Maxillofacial Surgery, Medicine, and Pathology for the Clinician presents key clinical information on oral surgery, medicine, and pathology in a single, easy-to-use resource, covering procedures performed in the dental clinic in a clear but concise manner and putting key details at the clinician’s fingertips.

Clinical scenarios are clearly described with treatment flow paths, and to enable seamless reader comprehension, charts and algorithms also support the text. The text focuses on essential office-related topics that are not esoteric but rather common in occurrence. The book speaks directly to topics of interest that will add value to the practitioner’s practice. Major surgical procedures not commonly performed by practicing oral surgeons are not included.

Overall, the text contains important up-to-date information that can be immediately put to use in clinical practice.

Oral and Maxillofacial Surgery, Medicine, and Pathology for the Clinician covers sample topics like:

• Patient assessment and significance of medical history review, the need for antibiotic prophylaxis (when, where, and how), and review of local anesthesia
• Diagnosis, treatment, and prevention of office medical emergencies and stocking in the dental office to deal with emergencies
• Basic review of oral mucosal lesions and treatment, review of antibiotic, oral sedation techniques and IV sedation overview, and basic and advanced exodontia
• Diagnosis and treatment of common post extraction complications and diagnoses and management of acute and chronic oral pain

The full scope of oral surgery is thoroughly covered in this multidisciplinary, current reference, making Oral and Maxillofacial Surgery, Medicine, and Pathology for the Clinician an essential tool for oral and maxillofacial surgeons, general dentists, and dental students looking to build upon their foundations of practical knowledge.
