Immunoexpression of RANK, RANKL and OPG in sporadic odontogenic keratocysts and their potential association with recurrence.

Background: Odontogenic keratocysts (OKCs) are clinically aggressive lesions with relatively high recurrence rates. Dysregulation of functional equilibrium in the RANK/RANKL/OPG system is responsible for osteolysis associated with the development of OKCs. Previously published findings imply that immunoexpression of these 3 proteins may correlate with bone resorption activity in OKCs.

CBCT for estimation of the cemento-enamel junction and crestal bone of anterior teeth.

The aim of the study is to evaluate the usefulness of cone-beam computed tomography (CBCT) in the assessment of the relationship between the cemento-enamel junction (CEJ) and bone crest of the anterior mandibular cortex. The study population comprised 39 males and 61 females, aged 18-71. A GENDEX GXCB-500 machine, i-CAT Vision and CorelDraw 9 software were used.

Investigation of clinicopathological parameters and expression of COX-2, bcl-2, PCNA, and p53 in primary and recurrent sporadic odontogenic keratocysts.

Objectives: Odontogenic keratocyst (OKC) presents considerable variation in aggressiveness and propensity for recurrence, yet hitherto, no explicit clinicopathological features have been determined to clearly demonstrate the potential for relapse. This retrospective study aims to investigate the prognostic relevance of various clinicopathological features as well as immunoexpression of COX-2, bcl-2, PCNA, and p53 in sporadic OKC.

Materials And Methods: Among 41 patients with OKC treated by enucleation, the frequency of recurrence for various clinicopathological features as well as immunoexpression for COX-2, bcl-2, PCNA, and p53 was evaluated.

Relationship between anterior mandibular bone thickness and the angulation of incisors and canines-a CBCT study.

Objectives: The morphology of the maxillary and mandibular alveolar cortex plays an important role in the planning of orthodontic treatment. Cone-beam computed tomography (CBCT) provides a precise demonstration of anatomical structures. Therefore, the aim of this paper was to evaluate what influence the position of incisors and canines have on the dimensions of the cortical and spongious bone of the anterior mandibular alveolar process.

An evaluation of selected oral health indicators and cariogenic bacteria titer in patients with Helicobacter pylori.

Background: Studies based on polymerase chain reaction (PCR) techniques indicate that Helicobacter pylori can be constantly or temporarily present in the oral cavity in virulent or non-virulent form. Streptococcus mutans exerts a strong inhibitory effect on H. pylori.

Intraosseous Lipoma of the Mandibula: A Case Report and Review of the Literature.

Lipoma is a benign tumour originating from mature adipose tissue. It can occur in any place in the body where adipose tissue is located. Intraosseous lipoma is a very rare bone tumour.

Maxillary fibrous dysplasia associated with McCune-Albright syndrome. A case study.

McCune Albright syndrome (MCA) is a rare complication of genetic origin. The authors present a case study of a patient with MCA diagnosed with multifocal fibrous dysplasia in his limb and craniofacial bones. The symptoms of the disease in the patient's facial and oral tissue and the treatment administered have been described.

Canine transmigration accompanying mandibular retrognathism secondary to osteitis.

Unlabelled: Transmigration is a tooth pathology in which the migrating tooth bud passes the median plane.

Methods: This study is a presentation of the diagnostic and therapeutic outcomes in the cases of 4 stomach teeth transmigrations diagnosed in 3 patients with mandibular retrognathia which was a complication after osteitis in the postnatal period and infancy.

Results: Extending imaging diagnostics to include CT, most preferably CBCT, makes it possible to precisely evaluate a transmigrated canine's position and to plan a course of treatment.

A radiographic assessment of the regeneration process in post-operative alveolar bone defects in patients with different IL-1B-511 genotypes.

Background: IL-1 is the main regulator of inflammatory reactions. This cytokine also plays an important role in bone tissue remodeling processes. The IL-1α-coding gene and the IL-1β-coding gene are located on the long arm of chromosome 2.

Use of the piezosurgery technique for cutting bones in the autotransplantation of unerupted third molars.

Autotransplantation is a well-known method used in oral surgery. However, risk of failure, most commonly resulting from root resorption of the transplanted tooth or ankylosis, is quite high. Piezosurgery with specific device tip vibration frequencies enables selective tissue cutting, and therefore, tooth buds or teeth can easily be removed from bones with little injury to periodontal fibers or bud follicles.

A comparative clinical study on human tooth extractions: flap vs flapless buccal surgery.

This study assessed the viability of bone and soft tissue healing at the wound extraction site, when the wound was both covered and not covered with a mucoperiosteal flap. In total, 40 patients were enrolled in the clinical study and were randomly allocated to each treatment cohort group.

Comparison of cryotherapy and photodynamic therapy in treatment of oral leukoplakia.

Oral leukoplakia is a pre-malignant lesion of the oral mucosa. The aim of this study is to compare the curative effects of photodynamic therapy and cryotherapy in the treatment of oral leukoplakia. The first group, treated by photodynamic therapy (δ-aminolevulinic acid (ALA), 630-635 nm wavelength), consisted of 48 patients suffering from leukoplakia.

The role of autofluorescence diagnostics in the oral mucosa diseases.

Background: Laser-induced fluorescence diagnostics (LIFE) can be used as an imaging system of precancerous and neoplasmatic lesions of oral mucosa. LIFE system utilizes healthy and neoplasmatically changed tissue in autofluorescence, without using any fluorescence substances. Neoplasmatic lesions are visible in pseudo colors, healthy tissue as a shade of green color and abnormal tissue as a shade of red color.

[Complications after alcoholization of mental nerve].

Trigeminal neuralgia (TN) is a syndrome affecting usually one half of the face and consisting of severe pains within one or more branches of the nerve. One of the methods for conservative treatment is using anesthetic drugs in the form of perineural sensory branch blockades n. V.

[A rare case of neurilemmoma of the floor of the mouth].

Neurilemmoma is a benign neoplasm of neuroectodermal origin. The authors present a rare case of this lesion localized in the oral cavity. Clinical symptoms, histologic structure of the tumor, methods of treatment and differential diagnosis are described.

[Comparison of analgetic effect of magnetic and laser stimulation before oral surgery procedures].

Oral surgery procedures are often the cause of painful sensations because of their tissue invasiveness. To avoid these sensations a wide use of nonsteroid antiinflammatory drugs is usually accepted. Because of plenty side effects of these drugs alternative antipain agents are desired.
