Collaborative dentistry is redefining the dentist's role within the healthcare system. Many people visit the dentist more often than they see their primary care physician, making the dental office a strategic point of contact for detecting early signs of disease and intervening in a timely manner. 

What is interdisciplinary work in dentistry?

Interdisciplinary work in dentistry involves coordinated, two-way collaboration between dentists and other healthcare professionals. Unlike the multidisciplinary approach, in which various specialists work independently, the interdisciplinary model is based on the exchange of knowledge and joint decision-making regarding both diagnosis and treatment strategies. 

Dentists treat oral conditions and interpret oral signs as potential indicators of systemic diseases: acting as a bridge between specialties. This dynamic is observed on a daily basis; for example, a patient with severe periodontitis who does not respond to conventional treatment may be referred to internal medicine to rule out diabetes, while a patient with mouth breathing may require the intervention of orthodontists to address malocclusion, as well as otolaryngologists and speech therapists. 

Oral and Maxillofacial Surgery: Medical Coordination for Complex Cases

Oral and maxillofacial surgery is one of the most interdisciplinary fields in clinical practice. The treatment of tumors, fractures, deformities, and complex reconstructions requires close coordination with specialties such as oncology, cardiology, otolaryngology, neurology, and orthopedics. This collaboration facilitates the planning of advanced surgeries, minimizes anesthetic and cardiovascular risks, and improves postoperative rehabilitation.

Periodontitis: Interdisciplinary Teams for a Better Prognosis

Periodontitis has well-documented links to diabetes mellitus: poor glycemic control exacerbates periodontal disease and complicates metabolic control. In turn, chronic inflammation is associated with an increased risk of cardiovascular disease and other inflammatory conditions. Collaboration with internal medicine, endocrinology, and cardiology helps reduce systemic risk and improve the patient’s overall prognosis. 

Orthodontics: An Interdisciplinary Approach to Respiratory Function and Craniofacial Development

Orthodontics is also linked to respiratory function, craniofacial development, and musculoskeletal balance. Conditions such as mouth breathing, airway obstruction, facial growth abnormalities, and muscular dysfunctions benefit from an interdisciplinary approach involving otolaryngologists, pediatricians, physical therapists, speech-language pathologists, and maxillofacial surgeons. This coordination is essential in cases of sleep apnea, oral habits in children, or complex malocclusions requiring a surgical approach. 

Pediatric Dentistry: Personalized Care Through Collaborative Medical Care

Since pediatric dentistry facilitates the early detection of genetic syndromes, developmental disorders, and rare diseases, working within an interdisciplinary model alongside pediatrics, nutrition, and neurology allows us to identify harmful oral habits and analyze neurological conditions that may affect development and oral health. It is possible to tailor treatments to each child’s specific needs and coordinate the approach with the family and school environments.

Oral Medicine: Early Detection and Diagnostic Coordination

Potentially malignant lesions, as well as autoimmune and complex mucocutaneous disorders, often present clinical signs in the oral cavity; therefore, oral medicine is key to their early identification. Collaborative work with dermatology, immunology, and hematology facilitates early diagnosis and prevention of oral cancer, in addition to improving the management and follow-up of complex diseases.

Dentistry for Special Needs Patients: Tailored Treatments Through Coordinated Care

Dental care for patients with disabilities, cognitive disorders, or complex systemic diseases requires collaboration with internal medicine, psychiatry, neurology, and geriatrics. In this case, an interdisciplinary approach facilitates the provision of more effective care, with tailored treatment plans, while improving treatment adherence and the experience of both the patient and their support network.

Why is interdisciplinary work so important?

The oral cavity can reveal inflammatory, immunological, and metabolic changes before systemic symptoms appear, and it is estimated that more than 90% of systemic diseases present some oral sign at some point during their course. Integrating different perspectives allows for more accurate diagnoses and personalized treatments that improve treatment adherence and patients’ quality of life.

The World Health Organization recognizes the interdisciplinary approach as a key strategy for reducing the burden of oral diseases, particularly in low-income countries where integrated care helps reduce hospitalizations. Public programs have demonstrated that a preventive and coordinated model reduces tooth loss and the prevalence of caries in the population.

How to Implement Interdisciplinary Work in Daily Practice

Step 1. Comprehensive medical history

Gather information on systemic diseases, medications, family history, and lifestyle habits to identify risk factors that may affect dental treatment.

Step 2. Identifying warning signs

Be on the lookout for oral lesions, persistent inflammation, bleeding, delayed healing, unexplained pain, or other signs that may indicate a systemic condition.

Step 3. Communicating with the patient

Clearly explain to the patient why the referral is necessary, what is expected of each specialist, and how this will benefit both their oral and overall health.

Step 4. Structured referral

Send a report to the relevant specialist, including a preliminary diagnosis, medical history, planned treatments, photographs, and specific questions.

Step 5. Joint follow-up

Maintain open communication with the appropriate healthcare professional to receive feedback and adjust the dental treatment plan according to their Indications.

Step 6. Registration and Training

It is important to document the entire procedure in patients' medical records to ensure continuity of care and improve future protocols.
