Ciążowe zapalenie dziąseł ze szczególnym uwzględnieniem guzów ciążowych

During pregnancy periodontal tissues may become more susceptible to internal and external factors promoting inflammation. Changes in hormone levels, alterations in the periodontal tissue structure and a predisposition to dilating blood vessels during pregnancy may lead to a painful inflammation as a response to a slightest amount of biofilm. Tumor gravidarum emerges in 5% of pregnant women during the first or second trimester — it may recede and fade completely right after the labour when hormone levels normalize. This paper explains the aetiology and potential risk factors of pregnancy gingivitis.Podczas trwania ciąży tkanki przyzębia stają się bardziej wrażliwe na działanie czynników pochodzenia zewnętrznego i wewnętrznego. Ze względu na zmiany w gospodarce hormonalnej oraz tendencję do rozszerzania naczyń krwionośnych podczas ciąży, nawet niewielka ilość zalegającego biofilmu może doprowadzić do powstania wyraźnego stanu zapalnego i podrażnienia dziąseł. U 5% kobiet ciężarnych podczas pierwszego lub drugiego trymestru rozwija się nadziąślak, tzw. ‘guz ciążowy’, który może zmaleć lub całkowicie zniknąć po porodzie i unormowaniu się gospodarki hormonalnej. Praca wyjaśnia etiologię i przedstawia potencjalne czynniki ryzyka występowania zapalenia dziąseł u kobiet ciężarnych w świetle badań naukowych

Oral surgery application of Er:YAG laser

The laser beam is an alternative technique to traditional surgery applicable in many oral surgery cases. It enables to avoid suturing and thanks to decontamination features promotes healing process. The authors presented advantages and disadvantages of laser Er:Yag Kavo KEY 3, establishing the indications as well as working parameters in specific ceses. The conclusion of the research is that histopathologic evaluation is possible only in tissue probe larger than 3 squere mm. The photographs of 12 different cases shows the variety of possible laser Er:Yag application

Use of fractal analysis for bone assessment

Since Mandelbrot announced the concept of the fractal geometry, fractal analysis has been used in the description of various structures found in nature and biosignals. It has been used to interpret biological phenomena such as nervous tissue, vascular system, the electrical conductivity of the heart and EEG. In dentistry, there have been many attempts to analyze the structure of jaw bones to assess periodontal disease and osteoporosis. Many authors indicate that bone tissue has a fractal structure, and that the fractal analysis can be inexpensive and convenient screening instrument in the diagnosis of systemic diseases that cause changes in the image of bones. This article is a review of applications of fractal analysis in bone evaluation

Rare case of a huge odontogenic cyst of the mandible

Dentigerous cysts are one of the most common odontogenic cysts of the jaws, being associated with the crowns of permanent teeth, especially unerupted mandibular third molars. Bilateral and multiple cysts are usually found in connection with a number of syndromes that include cleidocranial dysplasia and Gorlin syndrome. In the absence of these syndromes, multiple dentigerous cysts are rare. Dentigerous cysts are the second most common odontogenic cysts after radicular ones, accounting for approximately 24% of all true cysts of the jaws. This paper presents an unusual case of a huge odontogenic cyst in a 49-year-old man associated with mandibular impacted premolars. During the last 30 years a similar case was observed in our material only once. They are randomly diagnosed in routine dental radiographs. The patients do not usually report pain or discomfort. Clinical examination reveals a missing tooth or teeth, facial asymmetry and a lesion of the bone which predisposes to pathologic fracture

Complications during the surgical removal of a wisdom tooth – a case report

Wisdom teeth eruption or malposition may cause many pathological conditions such as recurrent pericoronitis, abscesses, osteomyelitis, radiating spontaneous pains, cysts, and others. The disorders mentioned above are indications for third molar removal. The degree of difficulty of the procedure is connected with the impaction stage of the tooth. Mesioangular and distoangular impactions are the least favourable positions. The surgical procedure may involve many complications such as excessive bleeding, alveolitis, nerve paresis, bone fracture, damage, luxation, or unintentional adjacent tooth removal. A displacement of the whole or of fractured fragments of the tooth to the adjacent fascial spaces, though rarely described in the literature, is a very serious complication. The success of the operation depends not only on the surgeon’s knowledge and experience but also on effective complications management. In this paper the authors present the case of a patient who after the surgical removal of a wisdom tooth was treated for second molar subluxation with ligature immobilization and endodontic treatment

Analysis of predisposing factors for complications after surgical removal of mandibular wisdom teeth

Thrid molar extractions are very common and difficult procedures in oral surgery. Mandibular wisdom are removed for therapeutic or prophylactic reasons. Aim. The aim of the study was to assess the incidence of complications after surgical extraction of mandibular third molars, such as alveolitis, sensation disorders, lockjaw, abscesses, prolonged bleeding and intensified swelling sustained for over 7 days. Material and methods. Data was obtained from patient records from the Department and Clinic of Oral Surgery, Poznan University of Medical Sciences in 2004–2008. Results. Complications occurred in 51 patients (17,5%) with 291 third molar extraction in the mandible. The most common were alveolitis, sensation disorders and intensified swelling. Postoperative complications were observed more frequently in the women. Conclusions. 1. Early extraction of the third molar in the mandible reduces the risk and extent of the treatment and the procedure is better tolerated by the patient. 2. Extraction of third molars in the mandible in eldery patients undergoing periodic clinical and radiological examination should only be carried out when absolutely necessary. 3. Postoperative complications in women are generally more often reported

Skin barrier function in primary and secondary Sjögren’s syndrome patients

Sjögren’s syndrome (SS) is a systemic autoimmune disease. A large percentage of patients with SS suffer from dry skin, the cause and pathogenesis of which in this group of patients remains obscure. The aim of the present study was to investigate skin barrier function in patients with SS. Measurements of transepidermal water loss (TEWL) and hydration of stratum corneum (corneometry, CM) were performed in 30 female patients with SS (17 with primary SS and 13 with secondary SS), 20 patients with atopic dermatitis (AD) and 14 healthy controls. There were no statistically significant differences in TEWL values between the three investigated groups, while CM values were significantly decreased in patients with AD when compared with patients with SS and the healthy controls. Based on the obtained results, skin barrier function and hydration in patients with SS showed no functional alterations. </p
