MORPHOLOGICAL CHANGES IN PERIODONTAL TISSUE DURING PERIODONTITIS.

Periodontitis is the most common oral disease worldwide and is the leading cause of tooth loss. It is considered to be a major burden in terms of costs of treatment and preventive measures. According to the systematic reviews, there is a link between periodontitis and cancer.

INFLUENCE OF PERIODONTITIS ON SOMATIC DISEASES AND THE ROLE OF ORTHODONTICS IN COMBINED TREATMENT OF PERIODONTITIS (REVIEW).

The literature review was conducted in order to assess correlations between periodontics and orthodontics, effectiveness of the orthodontic treatment in patients with periodontitis. Also, causative agents of periodontitis, risk factors and its influence on systemic diseases are discussed and analyzed. The literature review was carried out several databases such as PubMed, Google Scholar, Scopus, Web of Science and Medline.

[PATHOMORPHOLOGICAL CHANGES UNDER LATENT MASTOIDITIS].

In our opinion it is caused by incomplete awareness of the distribution of pathological process and the character of morphological changes in the patients. In this regard, we studied structural changes in the soft and bone tissue taken from various cavities of the middle ear system. Operating material was formed in paraffin after the fixation and proper processing.

Rare cases of disorders of sex development (DSD) in adolescents with female phenotype.

Background: Disorders of sex development (DSD) belong to uncommon pathologies; in addition, there are especially rare forms, such are ovotesticular disorders (OT), Turner syndrome and early malignisation of intraabdominal located gonads in the cases of androgen insensitivity syndrome.

Objective: In this article we present four rare cases of DSD in female phenotype adolescents: two cases of ovotesticular DSD with 46,XX and 46,XY karyotypes; one familial case of androgen insensitivity syndrome (AIS) with early malignancy (19-year-old) of intra-abdominally-located testicle in older siblings, and a case of spontaneous menstruation in a patient with Turner syndrome and mosaic karyotype 45,X/47,XXX. Rare cases of DSD are connected with diagnostic and management difficulties and so description of each such case and collection of data in this field is very important from a scientific, as well as a practical, point of view.
