Introduction
The course Integrative Dentistry: Microbiome, Diet, and Lifestyle is offered as an elective subject in the Degree in Dentistry, aimed at providing a comprehensive, cross-disciplinary, and updated vision of oral health. Traditionally, dentistry has focused on the interventionist treatment of local pathologies; however, contemporary scientific evidence unequivocally demonstrates that the oral cavity is not an isolated system.
This course was created to connect dental practice with the individual's systemic health, thoroughly examining the role of the oral microbiome and its interaction with the human body's biological pathways. Throughout the course, students will analyze the pathophysiological mechanisms through which environmental and daily factors —such as diet, sleep, physical activity, and chronic stress— influence microbiota balance (dysbiosis), the immune system, and, consequently, the onset or resolution of the most prevalent oral diseases.
Relevance and Interest for the StudentThe relevance of this subject for future dentists is paramount, as it addresses a paradigm shift in the healthcare sector towards a more preventive, personalized, and predictive medicine. Students will find distinct academic and professional value in this course through the following key areas:
-
Understanding Holistic Health: Students will learn to interpret oral health not as an isolated event, but as a reflection of the patient's systemic and metabolic status.
-
Critical Thinking and Evidence-Based Practice: Students will be equipped with the necessary tools to critically analyze the latest scientific advances in microbiomics and human nutrition applied to dental clinics.
-
New Clinical Skills (Brief Counseling): Students will acquire communication and clinical skills to design health education strategies. They will learn to implement "brief counseling" protocols at the dental chair, enabling them to guide patients in improving their lifestyle habits (anti-inflammatory diet, stress management, sleep chronobiology) as an integral part of successful dental treatment.
Ultimately, this elective course offers students a cutting-edge perspective, transforming future professionals into comprehensive health agents capable of treating the root cause of pathologies rather than just their structural consequences.
Pre-course requirements
Without specific requirements.
Objectives
-
To understand the concept of integrative dentistry and the fundamental role of the oral-gut microbiome axis in health and disease.
-
To analyze how diet, nutrition, and lifestyle habits modulate microbiome composition and influence systemic and oral pathophysiological mechanisms.

To know the biological foundations, indications, and limitations of using probiotics, prebiotics, and postbiotics in current dental therapeutics.
-
To develop critical reading skills of scientific literature in the fields of microbiomics and lifestyle medicine, as well as its direct transfer to evidence-based clinical practice.

Syllabus
This course offers a cross-disciplinary and interconnected journey from the foundations of systems medicine to its practical application in the dental clinic. The content is structured into three main blocks:
-
Biological Foundations of the Mouth-Body Axis: Study of the ecology, diversity, and functions of the oral and gut microbiome, as well as their complex interactions with the host's immune system and metabolism (metabolic endotoxemia and systemic low-grade chronic inflammation).
-
Environmental Modulators and Lifestyles: Analysis of the impact of nutrition (pro- and anti-inflammatory dietary patterns, and key micronutrients), sleep, circadian rhythms, chronic stress, and physical activity on oral tissue homeostasis. Furthermore, the therapeutic use and clinical evidence of biotics (probiotics, prebiotics, and postbiotics) will be evaluated.
-
Clinical Translation and Communication: Development of critical appraisal and evidence-based medicine skills to successfully transfer scientific literature into daily clinical workflows, combined with the mastery of motivational interviewing and brief lifestyle counseling protocols directly from the dental chair.
Teaching and learning activities
In person
The teaching methodology of this course is based on an active, student-centered learning approach, balancing scientific rigor with real-world clinical application. The activities are structured into two main components:
1. In-Person Activities (Directed Learning)-
Participatory Lectures: Dynamic theoretical sessions covering fundamental biological and clinical concepts. Open debate, real-time problem-solving, and brief clinical case analyses are promoted through interactive questioning.
-
Critical Appraisal Seminars: Practical sessions dedicated to analyzing high-impact scientific papers in microbiomics, nutrition, and lifestyle medicine. Students learn to evaluate study methodologies, commercial biases, and evidence strength.
-
Clinical Communication Workshops: Hands-on workshops and role-playing simulations designed to train students in motivational interviewing, managing patient resistance, and implementing "brief counseling" protocols within the dental environment.
-
Short Team Presentations: Oral presentations where student groups defend the integration of scientific evidence into a simulated clinical case or a cutting-edge topic, followed by an open discussion with the class.
-
Personal Study and Guided Readings: Independent review of course materials, mandatory literature analysis, and targeted reading of the scientific papers assigned for the seminars.
-
Presentation Preparation and Teamwork: Group research, critical appraisal of data, and design of the short presentation for the oral defense sessions.
Evaluation systems and criteria
In person
Assessment System and Criteria
-
Final Examination (60% of the final grade): A written exam or structured practical test designed to evaluate theoretical knowledge and clinical reasoning skills.
