Description: Hypertension is a common major systemic disease and 1 of the most significant causes of mortality worldwide. Persistent hypertension is 1 of the risk factors for stroke, heart attack, heart failure, and arterial aneurysm and is a leading cause of chronic kidney failure. Common medications used to treat hypertension include beta blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, and calcium channel blockers. The purpose of this study was to assess the prevalence of periapical abscesses in patients with different types of hypertension conditions and to evaluate the effect of commonly used antihypertensive medications on the prevalence of periapical abscesses.
- Assess the risk factors for patients with hypertention.
- Identify the common medications used to treat patients with hypertension.
- Recognize the possible prevalence of periapical abscesses in patients treated with different antitensive medications.

Description: The pathological extension of periapical infection into the maxillary sinuses is often overlooked in clinical medical and dental practice, with its sequelae often misdiagnosed as rhinogenic sinusitis. This lecture explains and illustrates the similarities, distinguishing differences, and frequent inter-relationship between endodontic disease and paranasal sinus infections. The associated clinical and radiographic findings of maxillary sinusitis of endodontic origin (MSEO) are explained using many real-world clinical case examples with an update on the current literature. Emphasis is placed on the importance of CBCT imaging, magnification, proper terminology, and clinical expertise for rendering both non-surgical and surgical endodontic treatment when indicated. The goal is to help practitioners distinguish rhinosinusitis from odontogenic sinusitis, and specifically MSEO, in an effort to improve the health of patients through accurate diagnosis, appropriate treatment, and improved communication between endodontists and ENT specialists.
Learning Objectives:
- Describe the clinical symptoms and radiograph similarities and differences between rhinogenic sinusitis and the various forms of odontogenic sinusitis.
- Describe the progression and pathogenic effects of apical periodontitis on the sinus tissues and the associated clinical and radiographic findings of maxillary sinusitis of endodontic origin (MSEO) using current terminology.
- Describe the importance of proper endodontic management for successful treatment of MSEO, recognizing the complexity of maxillary posterior canal morphology and the unique non-surgical and surgical challenges present with maxillary posterior teeth proximate to the maxillary sinus.

There is evidence that acute periapical lesions present a greater potential for cyst formation. Recently, it was found that these lesions have cells with characteristics of pluripotent stem cells, which may influence cyst development. However, a more complete phenotype investigation of stem cells in a specific sample of periapical abscesses is required. The aim of this study was to analyze the immunohistochemical expression of mesenchymal stem cell (MSC) markers in periapical abscesses and to evaluate differences in their expression in relation to acute and chronic periapical lesions.
At the conclusion, participants should be able to:
- Describe the pathological pathway of cyst formation
- Explain the importance of characterizing stem cells present in the periapical lesions
- Discuss the relationship between acute periapical abscess and cyst formation
