Periodontitis. Stomatitis. Epulis.

Relevance of the topic: Periodontal disease and oral mucous membranes extremely diverse, occur quite often lead to structural changes in all the teeth-jaw system, and if left untreated can lead to severe complications. Knowledge of the etiology, pathogenesis, staging of disease, morphological changes in this pathology is the basis for timely and correct diagnosis, adequate treatment purposes, and prevention of complications. These skills and knowledge obtained in class are required to dentists of all disciplines; they will help with the development of the relevant sections in the departments of medical, surgical and prosthetic dentistry.

Purpose: able to analyze the morphological changes (macro-and microscopic) in the mouth of the patient at various diseases of the mucous membranes of the mouth and periodontal (stomatitis, epulis), to represent their pathogenesis, complications, outcomes.

The specific objectives The objectives of the entry-level

1. Determine the morphological changes characteristic of acute forms of periodontitis.

1. Recognize the macroscopic and the microscopic structure of the gums, periodontal bone dental alveoli (Department of the normal anatomy and histology).

2. Determine the morphological changes characteristic of chronic periodontitis.

2. Represent the anatomical (macroscopic and histological structure), lips, tongue and soft tissues of the oral cavity (Department of the normal anatomy and histology).

3. Recognize and interpret morphological changes in various forms of acute stomatitis.
