Dental Surgery and Systemic Health: An Integrative Approach

The human body is interconnected, and various systemic conditions have implications for the oral cavity; therefore, dental surgery benefits from a collaborative approach among professionals from different fields: cardiology, oncology, and otolaryngology. Having access to a complete medical history and maintaining open communication among specialists helps identify warning signs early and improve patient recovery. 

Dental surgery and cardiology

The link between dental surgery and cardiology is well documented. A large number of patients have cardiovascular diseases, and their pharmacological treatments and clinical conditions directly influence the planning and performance of dental surgical procedures. Coordination between specialists in both fields helps ensure a safe and effective procedure. 

1. High blood pressure

High blood pressure is a common condition, and if it is well controlled, it is safe to undergo routine dental procedures without complications. Nevertheless, it is essential to monitor blood pressure during the procedure, as the associated stress can cause it to spike suddenly and increase the risk of complications.

2. Heart failure and arrhythmias

Patients with heart failure or arrhythmias may experience changes in hemodynamic function that require certain adjustments to anesthesia and the implementation of precautions to prevent their condition from worsening during invasive procedures. For example, heart failure can limit a patient’s ability to remain in the same position for prolonged periods due to the onset of shortness of breath or hemodynamic instability.

3. Anticoagulation and antiplatelet therapy

These medications are typically prescribed for people with atrial fibrillation, a history of thrombosis, heart valve replacements, or a history of stroke or thrombosis. In most cases, the American Dental Association and the societies of anesthesiology and cardiology recommend continuing anticoagulation prior to dental procedures, while always assessing the risk of bleeding. 

For cases of increased bleeding (multiple extractions, extensive surgeries), the preoperative plan for the anticoagulated patient with the cardiologist. Discontinuing it without supervision can cause serious blood clots, and failure to control local bleeding can complicate recovery. 

4. Prevention of complications

Some patients at high risk of infectious complications, such as those with heart valve prostheses or a history of bacterial endocarditis, should receive preventive antibiotics prior to invasive dental procedures. The decision to administer antibiotic prophylaxis should be based on specific criteria and made through interdisciplinary coordination.

Dental Surgery in Cancer Patients

Collaboration between dental and oncology specialists is essential for patients undergoing chemotherapy, radiation therapy, targeted therapies, or immunosuppressive therapies. These treatments can affect their oral health and complicate recovery following surgical procedures. 

1. Mucositis and xerostomia

Chemotherapy and radiation therapy can cause oral mucositis, making it difficult to eat and maintain good oral hygiene, as well as xerostomia, which increases the risk of infections and slows healing. Before any dental procedure, the type of cancer treatment the patient is receiving should be considered, and coordination with the dentist is necessary to schedule the procedure at the most appropriate time. 

2. Drug-induced osteonecrosis 

Osteonecrosis osteonecrosis of the jawbone can occur in cancer patients taking medications such as bisphosphonates or denosumab. This is more common in cases of bone cancer, bone metastases, or breast and prostate cancer, especially following tooth extractions. 

It is recommended that you have a complete dental examination and address any issues before starting intravenous medication. Coordinating with oncologists helps determine the type of medication, choose the safest time for the procedure, and implement preventive strategies. 

3. Immunosuppressive therapies

Immunocompromised patients are at higher risk of developing postoperative infections; therefore, it is important to update their medical history and verify the information with immunologists or oncologists. It may be necessary to plan for prophylactic antibiotics and schedule more frequent follow-up visits after surgery to detect potential complications before they occur. 

Dental Surgery and Otolaryngology

Due to the anatomical proximity of the oral cavity, maxillary sinus, and other deep facial structures, dental surgery and otolaryngology (ENT) are closely related. A problem in one area can affect another. For example, periapical infections in upper molars can spread to the maxillary sinus, and during extractions of upper molars, sinus lifts, or cyst removals, there is a risk of sinus perforation. 

Collaborating with otolaryngologists is particularly useful when there is a risk of fractures, involvement of the paranasal sinuses, or respiratory and sinus disorders. Collaboration between the two fields facilitates radiologically assess the anatomy before performing any procedure, as well as allowing for comprehensive treatment of dental sinusitis or sinus perforations. 

Identification of systemic risks and interdisciplinary coordination

A good clinical approach begins with a complete medical history and a thorough examination of the patient. The dentist must have detailed information about the patient’s medical history and be able to detect clinical signs that may indicate systemic complications, such as changes in the oral mucosa in cancer patients or abnormal bleeding in patients on anticoagulants.

Maintain open line of communication with other medical specialists—whether with cardiologists, oncologists, or otolaryngologists—is essential for tailoring treatments and implementing preventive measures. The use of shared clinical reports and interprofessional consultations facilitates teamwork and improves the outcomes of any intervention. 

In short, interdisciplinary teamwork reduces the risk of both local and systemic complications and allows for personalized planning tailored to each patient’s needs, in addition to increasing safety when treating complex patients and improving their quality of life and experience. Today, this interdisciplinary approach is key to the dental surgeon’s practice.
