X-rays, cone beam computed tomography (CBCT), magnetic resonance imaging (MRI), and positron emission tomography (PET) scans can help visualize the extent of the tumor, its relationship with surrounding structures, and potential metastatic spread.
3. Biopsy and Histopathological Evaluation: A definitive diagnosis of bone sarcomas is made through a biopsy procedure. Dentists should collaborate with oral and maxillofacial surgeons or oncologists to perform a biopsy and send the tissue samples for histopathological evaluation. The biopsy results provide important information for treatment planning and prognosis.
4. Collaboration with Oncology Specialists: Dentists play a crucial role in collaborating with oncology specialists, including orthopedic oncologists and medical oncologists, for the accurate diagnosis, staging, and overall management of bone sarcomas. Sharing information, discussing treatment plans, and coordinating care contribute to comprehensive patient management.

Treatment Considerations for Bone Sarcomas

1. Surgical Management: Surgery is a common treatment approach for bone sarcomas. The extent of surgical intervention depends on factors such as tumor size, location, and the involvement of surrounding structures. Dentists should collaborate with the surgical team to ensure appropriate dental care before and after surgery, including dental extractions, oral hygiene instructions, and post-operative support.
2. Chemotherapy and Radiation Therapy: Bone sarcomas may require adjuvant treatments such as chemotherapy or radiation therapy. Dentists should be aware of the potential oral complications associated with these treatments, such as mucositis, xerostomia, and increased susceptibility to infections. Supportive oral care, including preventive measures and symptom management, is crucial during these treatment phases.
3. Rehabilitation and Prosthetic Considerations: After the completion of bone sarcoma treatments, patients may require rehabilitation and prosthetic considerations to restore oral function and aesthetics. Dentists should work closely with prosthodontists and other specialists to develop customized treatment plans, including dental implants, dentures, or other restorative options.

Bone Destruction and Resorption: Bone sarcomas can lead to significant bone destruction and resorption in the oral cavity. This can result in bone pain, loosening of teeth, and even pathologic fractures. Dentists should carefully assess the condition of the alveolar bone and surrounding structures to detect any signs of bone destruction.

Facial Deformities and Asymmetry: Advanced bone sarcomas in the oral cavity can cause facial deformities and asymmetry. These changes may affect the patient’s self-esteem and quality of life. Dentists should be sensitive to the psychological impact of these deformities and work in collaboration with maxillofacial surgeons to develop appropriate treatment plans, which may include reconstructive surgery.

Nerve Involvement and Sensory Changes: Depending on the location and size of the bone sarcoma, the involvement of nerves in the oral cavity can lead to sensory changes. Patients may experience numbness, tingling, or altered sensations in the affected areas. Dentists should conduct a thorough sensory examination and consider the potential impact on dental procedures and oral health.

Metastatic Spread to the Jawbones: Bone sarcomas can metastasize to the jawbones, causing secondary tumors in the oral cavity. Dentists should be aware of the possibility of metastatic spread and collaborate with oncology specialists to ensure proper evaluation and management of these cases.

Oral Health Maintenance during Treatment: Patients undergoing treatment for bone sarcomas may experience side effects that affect their oral health, such as xerostomia (dry mouth), increased susceptibility to infections, and compromised oral hygiene. Dentists should provide guidance on oral hygiene practices, recommend saliva substitutes if necessary, and closely monitor the oral health status of these patients throughout their treatment journey.

Long-Term Follow-Up and Surveillance: Regular follow-up and surveillance are crucial for individuals who have been treated for bone sarcomas in the oral cavity. Dentists should schedule periodic visits to monitor the patient’s oral health, assess the stability of the treatment site, and screen for any signs of recurrence or new tumors.

Supportive Care and Symptom Management: In addition to providing dental care, dentists can offer supportive care and symptom management strategies for patients with bone sarcomas. This includes addressing pain, discomfort, oral complications, and psychosocial support. Collaborating with palliative care specialists can also be beneficial in managing symptoms and improving the patient’s quality of life.

Research and Advancements: Ongoing research and advancements in the field of bone sarcoma management contribute to improved diagnosis, treatment options, and outcomes. Dentists should stay updated with the latest research findings, attend relevant conferences, and collaborate with researchers to enhance their knowledge and provide the best possible care to patients.

Jaw Pain and Stiffness: Bone sarcomas in the oral cavity can cause jaw pain and stiffness, which may affect the patient’s ability to open and close their mouth comfortably. Dentists should assess the range of motion of the jaw and consider the impact on oral function and quality of life.

Tooth Mobility and Displacement: As bone sarcomas progress, they can lead to tooth mobility and displacement. Patients may notice that their teeth become loose or shift from their original positions. Dentists should evaluate the stability of the teeth and consider appropriate dental interventions, such as splinting or extractions, to address mobility and maintain oral function.
