The structure of leukocyte infiltrates in gingiva of 80 patients of various ages and gender with chronic apical periodontitis was studied using light microscopy with the application of monoclonal antibodies detecting CD38 antigen. Gingival tissues of practically of all the patients with periodontitis contained 2 types of leukocyte infiltrates: infiltrates with the low plasma cell content and high numbers of neutrophils and structures with high number of plasmocytes and low concentration of neutrophilic granulocytes. Within the gingival epithelium in patients with chronic apical periodontitis CD38 + cells were absent. The histogenesis of gingival leukocyte infiltrates in chronic apical periodontitis is discussed with the special emphasis on the role of plasma cells in the development of the pathological process.

Aim: This study aimed to evaluate the effects of chronic consumption of two sugar-sweetened carbonated soft drinks - one containing caffeine (Coca-Cola®) and one without (Sprite®) - on the progression of periapical lesions and the levels of pro-inflammatory cytokines in rats.
Methodology: Twelve Wistar rats were divided into three groups (n = 4): Control group, Coca-Cola group and Sprite group. The rats in Coca-Cola and Sprite groups were given ad libitum access to their respective soft drinks for 3 months, while the Control group received filtered water.

Background: Chronic pulmonary abscess usually results from bacterial or mycobacterium infection, but rarely from aspergillosis. Chronic pulmonary aspergillosis is usually found in a person with structural lung disease or immunocompromise. Here, we report a case of chronic lung abscess of aspergillosis without immunocompromise, structural lung diseases or even clinical symptoms.

Background: Chronic apical periodontitis (AP) may influence the outcome of root canal treatment. Thus, it is important to diagnose AP using the best method available. This research was done to compare the diagnostic accuracy of parallel periapical radiography (PR) and different field of views (FOVs) of cone-beam computed tomography (CBCT).

Hypereosinophilic syndrome (HES) is traditionally described as chronic peripheral eosinophilia with involvement of various organs and systems, including the heart and nervous system. In this report, we describe cardiac involvement and border zone stroke in a patient with idiopathic HES. A 37-year-old woman presented with sudden right-sided weakness and slurred speech, which began four days before admission, accompanied by palpitations, retrosternal exertional chest discomfort, dry cough, and progressive shortness of breath over approximately two months.

Objectives: This randomized prospective controlled trial investigated the effectiveness of different strategies of regenerative endodontic therapy on necrotic mature anterior teeth with chronic periapical periodontitis with 18 months follow up.
Methods: A total analyzed 51 adult participant with mature single rooted teeth having necrotic pulp with chronic periapical periodontitis (PAI ≥ 3) were selected. Patients had been randomly categorized into three distinct groups (n = 17 each group).
