Comprehensive Notes on Oral Pathology and Management

Clinical Presentation of Oral Cysts and Infections

  • Image Description: Presentation includes an image of a large cyst on the right side, possibly indicating various types of cysts:

    • Dentigerous cyst

    • Odontogenic tumor

    • Teratocyst

  • Consideration: The cyst is large enough that surgical resection may risk leaving the patient without sufficient lamina majora.

  • Management Strategy: To reduce cyst size, a decompression is suggested.

Infection Spread in the Oral Cavity

  • Infection Pathway: An infection in the mouth (monontogenic infection) spreads based on muscle insertion points:

    • Muscle insertions in the mandible and maxilla determine the direction of the infection.

  • Location Classification:

    • Below the Mylohyoid Muscle: Potential for submandibular, and possibly submental infections.

    • Above the Mylohyoid Muscle: Involvement with the floor of the mouth; if affecting the buccal area, may indicate vestibular involvement.

  • Maxilla Specifics:

    • Above Buccinator Muscle: Infection could localize at canine area or posterior maxilla.

    • Below Buccinator Muscle: Infection may lead to vestibular involvement.

Patient Instructions for Communication with Maxillary Sinus

  • Concerns: Suspected oroantral communication between mouth and maxillary sinus.

  • Patient Instructions:

    • Avoid holding the nose while closing the mouth.

    • Avoid tonicity of the closed mouth to prevent raising intraoral pressure, which may exacerbate the communication.

Post-extraction Patient Management

  • Precautionary Measures: For patients at risk of oroantral communication:

    • Patients should follow specific instructions for two weeks post-extraction.

  • Case Reference: A patient on SIPAD for drainage should manage their oral hygiene to change anaerobic bacterial flora, which could lead to decreased infection rates.

Antibiotic Use and Protocol Management

  • Antibiotic Concerns: Usage of materials for maintaining drainage such as oxygen-rich environments should be emphasized for anaerobic infections.

  • Laboratory Workup:

    • For anticoagulation, tests include:

    • PT (Prothrombin Time)

    • PTT (Partial Thromboplastin Time)

    • INR (International Normalized Ratio)

    • If platelets are low, checking bleeding time may be necessary.

  • Bleeding Time Assessment: Conducted by making a small incision for timing using a stopwatch.

Patient History and Medications

  • Case Example: A 60-year-old patient with multiple myeloma and bone metastases presenting with jaw pain and bleeding.

  • Medication Review:

    • Inclusion of Someta (generic name for a bisphosphonate) crucial as it’s linked to jaw necrosis.

  • Potential Diagnosis: Medication-related osteonecrosis (MRONJ) consistent with current medication history.

  • Preventative Action: Patients on bisphosphonates should have problematic teeth removed before initiating treatment.

Osteonecrosis Implications

  • Hyperbaric Oxygen Therapy: Indicated for osteoradionecrosis (ORN) but not for MRONJ due to different pathophysiology.

  • Indication Differences: ORN patients benefit from augmented vascularization, where MRONJ lacks these benefits.

  • Adjunctive Treatment: Must be approached differently when treating patients on antiresorptive medications.

Clinical Case Presentations in Upcoming Board Meeting

  • Topics to be Presented:

    • A plasmacytoma case, typically rare and often associated with multiple myeloma.

    • Medication implications relating to bisphosphonate management and necroses associated.

Specific Cases of Hematological Considerations

  • Case Reference: 72-year-old patient presenting with dental abscess potentially complicated by medications for osteoporosis.

  • Key Drugs of Interest:

    • Medications associated with major adverse outcomes when dental work is required.

  • Maxilla vs. Mandible Observations: Heightened incidence of complications noted in maxillary cases over mandibular cases.

Radiological Findings and Diagnosis

  • Periapical Radiolucent Lesion:

    • Lesion with clarity and diffuse boundaries indicative of root fracture.

  • Distinction of Conditions: Differentiating from other lesions based on appearance and absence of typical periapical findings.

Patient Presentation and Clinical Examination

  • Case Presentation of Oral Laceration:

    • Patient with significant cheek laceration developing swelling leading to fluid aspiration which yielded a serous fluid.

  • Relevant Discussion: The change and type of exudate signals underlying pathophysiological processes.

Recommended Referrals and Management Strategies

  • Referral for Infection Treatment: If endodontic treatment is required, clindamycin may be prescribed.
