Apoptosis is a physiological process that occurs in the human body throughout the entire life span. This process can be seen in the tissues of the stomatognathic system. A disorder in such programmed cell death processes leads to the development of pathological lesions. Among these are inflammation, osteolytic lesions and neoplastic hyperplasia. We put forward that future studies should concentrate on how to use the knowledge of apoptotic processes and their inhibitors in therapeutic processes involving the stomatognathic system.
The study presents a case of the rarely occurring totally retained fourth molar teeth simultaneously in maxilla and mandible. The appearance of supernumerary teeth is a relatively uncommon dental anomaly and it is rare for patients to have impacted fourth molars in two quadrant. The aim of this work is to describe the presence of unilateral (right) fourth molars in the maxilla and the mandible in a young female patient aged 24 years. Orthopantomogram revealed impacted lower third molars but also unerupted unilateral (right) upper and lower fourth molars. Before orthodontic treatment, the patient was subsequently admitted for removal of third and fourth impacted upper and lower molars under local anesthesia.
Among many substances used in clinical diagnosis, such as peripheral blood, gum homogenate, saliva and gingival pocket fluid, it is the latter that seems to bean extremely valuable diagnostic and research material. Identification of mediators in gingival crevicular fluid, both in the healthy gingival fissure, as well as in pathological periodontal pockets can be a valuable supplement to the initial diagnosis and describe the mechanism of gumorperiodontal diseases. Changes in the concentration of individual components in the gingival crevicular fluid may be used to assess the severity of periodontal disease. There are numerous methods for collecting fluid from the sulcus described: Micro-capillary drainage, micropipette drainage, rinsing pocket or drainage with the use of methylcellulose strips and then reading with Periotron. Gingival fluid is composed mainly of blood electrolytes and organic molecules, i.e. albumins, globulins, lipoproteins or fibrinogen and cellular components as well as peptides, bacteria and enzymes. Therefore gingival crevicular fluid (GCF) is treated as a window for noninvasive analysis of periodontitis, taking into account indicators and markers of connective tissue and bone destruction.
In adult life, proper bone metabolism requires efficient regulation of bone formation and resorption processes. Bone turnover markers allow for assessing the rate of bone formation and resorption processes. In menopausal period, female patients experience gradual reduction in blood estradiol levels. The deficit of estrogens leads to enhanced osteoclastogenesis and bone resorption. Alkaline phosphatase (ALP) is a membranebound enzyme that stimulates the osteoblast activity and bone mineralization. It is synthesized by osteoblasts and incorporated into the newly formed bone tissue. The produced enzyme stimulates the osteoblast activity and bone mineralization. The goal of this study is to determine the effect of hormone replacement therapy in postmenopausal women on the expression of alkaline phosphatase gene (ALPL) within the mucosal epithelium of the cheek and in peripheral blood lymphocytes. The studies show that hormone replacement therapy has no significant effect on the increase in ALPL expression within the mucosal epithelium of the cheek. Only in women having undergone ovarectomy (OV), the epithelial ALPL expression level was higher than in the remaining groups.
Central sleep apnea (CSA) is a disease characterized by repetitive episodes of the socalled central apneas during sleep. The disease has a very complex etiology. In clinical practice, the most important causes of CSA are disorders of the central nervous system, congestive heart failure or certain pathological changes of the respiratory muscles. We present a case of a 43-year-old male with severe CSA, who was successfully treated with BiPAP ST equipment.
