Description: ULTRASOUNDS REAL TIME IMAGING (USI) is and advanced complement in endodontic diagnostic techniques. Ultrasound real-time imaging, (echography ), widely used in most fields of medicine since its introduction in 1942, is based on the generation and reflection of ultrasound waves and on the different mechanical and acoustic properties of body tissues. USI does not use ionizing radiations, and thus it represents a safe exam. The most important features of USI are its safety and its ability to describe the content of the lesions within the maxillary bones, in terms of presence of solid tissue, different fluids and vascularity. The use of USI has been successfully applied to the endodontic field for the DETECTION and DESCRIPTION of apical periodontitis, for the DIFFERENTIAL DIAGNOSIS between CYSTIC and SOLID lesions of endodontic origin, and between endodontic lesions and non-endodontic lesions; and also for evaluating the short and long term outcome of orthograde and surgical endodontic treatment. An integrated system of CBCT and USI would provide the clinician with the tools for the complete assessment of apical periodontis.
Learning Objectives:
- Describe the imaging technique called Ultrasound real-time examination, its main features and its biological safety.
- Describe the most important advantages of using Ultrasound real-time examination when applied to the visualization and description of lesions of apical periodontitis in the mandible and in the maxillary bone, their content and vascularization.
- Describe the advantages of using Ultrasound real-time examination, as a complement to 3D radiographic examination, to differentially diagnose bone lesions with fluids or solid content, high, low, or no vascularity, to trace sinus tracts.

Course Description: During this session we will discuss the implications of the anatomical relationship of the maxillary sinus and the upper dentition. After presenting an overview of normal sinus anatomy and physiology, we will discuss the pathophysiologic processes that contribute to rhinosinusitis, emphasizing the differentiation between rhinogenic and odontogenic etiologies. We will use example cases to demonstrate these learnings.The pathological extension of endodontic disease into the maxillary sinus and its sequelae are often unrecognized in medical and dental practice. Despite extensive scientific recognition and reported high prevalence, dental infection manifesting in the maxillary sinus continues to remain under-appreciated, and often misdiagnosed and treated as rhinogenic sinusitis. This lecture explains the progression of endodontic infection in the sinuses and the associated clinical and radiographic findings. The goal is to help practitioners recognize maxillary sinusitis of endodontic origin (MSEO) through accurate diagnosis and appropriate treatment, and improve communication with physicians and ENT specialists.
At the conclusion, participants should be able to:
- Describe sinus anatomy and normal sinus physiology and the patholophysiologic processes that contribute to sinusitis.
- Summarize the diagnosis and treatment of rhinogenic sinusitis.
- Describe the progression and pathogenic effects of endodontic infection in the sinus and the associated clinical and radiographic findings of maxillary sinusitis of endodontic origin (MSEO).
