This subject is extending the basic knowledge in histology, microscopical anatomy and embryology in the areas of
head and neck as an important basis for dentistry studies. It covers following topics: Introduction to oral histology
and methods of examination of hard tissues. Microscopical structure of the tooth – enamel (arrangement, aging,
caries), dentin (arrangement and clinical relevance), cementum (arrangement and clinical relevance) and dental
pulp (arrangement, aging and function). Differences between the structure of deciduous and permanent teeth.
Microscopical arrangement of periodontal ligament, its function and clinical relevance. Arrangement of an alveolar
bone, clinical aspects of its remodelling. The structure of oral mucosa and its regionalization. Characteristics of
palatal mucosa, characteristics and description of mucosa of lips and cheeks, soft palate, tongue and gums.
Taste sense. Microscopical structure of gums, sulcus gingivalis, epithelial attachment, clinical relevance of gums.
General structure and survey of oral salivary glands. Big salivary glands – characteristics and description. Saliva.
Development and differentiation of germ layers. Stomodeum and facial development. The development of oral and
nasal cavities. The development of oral vestibule. The development of palate and nasal septum. The development
of upper and lower jaws. The development of the tongue. The development of the tooth (developmental stages, the
tooth bud and the tooth cap). The development of the tooth crown and of the root. Tooth eruption (timing of single
deciduous teeth eruption and the formation of the permanent teeth and the timing of their eruption). The
development of alveolar processes and of the periodontal ligament. The development of salivary glands.
Congenital defects of the orofacial region.
