Learning outcomes
At the end of the course the student have the preparation that allows to understand the morpho-functional bases of the human body's apparatus, with particular reference to the stomatognathic apparatus.
In particular, the student is able to recognize the microscopic structure of the eukaryotic cell, to identify the organizational and functional characteristics of the several tissues (eg mucous membranes of the oral cavity and salivary glands), to explore the development and physiological evolution of dental tissues, to have the basis for the interpretation of the physiopathological processes concerning the stomatognathic apparatus and to coordinate the knowledge of basic disciplines to recognize the cellular and tissue bases of pathological processes

The students will be strongly encouraged to take an independent approach to learning. They will be advaiced to adopt any international textbook in English available on-line. They will also be guided toward a critical use of internet-assisted documentation and histological archives of italian universities.
Teaching methods
Frontal lessons. The acquisition of the knowledge may be monitored with oral and written tests
Assessment methods
The students will be evalutated by oral exams on the basis of at least three questions on the subject of the course. The subject of two questions will be randomly chosen by the professors. One question will be chosen by the student.
At the end of the examination, the professor will score the performance of the student using a number ranging from 18 to 30 according to the interpretation indicated below.
Interpretation of the score:
- <18 – failure, not scored. The student fails to satisfactory address all of the questions.
- 18 Poor. The student inadequately addresses most of the questions with serious inherent weaknesses.
- 21– Fair. The student broadly addresses most of the questions, but there are significant weaknesses.
- 24– Good. The student addresses the questions well, but a number of shortcomings are present.
- 27– Very good. The student addresses the criterion very well, but a small number of shortcomings are present.
- 30– Excellent. The student successfully addresses all relevant aspects of the questions. Any shortcomings are minor.
- 30 cum laude. The student successfully addresses all relevant aspects of the questions with no shortcomings.
Teaching tools
