Lesson 1Laboratory tests to request: CBC, inflammatory markers (CRP, ESR), blood glucose, liver function tests, and relevant infectious serology (TB screening when indicated)Key lab tests for mouth workup like full blood count, swelling markers, sugar, liver check, germ blood tests, when needed, how to read, change thinking and safety.
CBC for anemia, infection, and bleeding riskCRP and ESR in acute and chronic inflammationBlood glucose and perioperative riskLiver function tests and drug metabolismTargeted serology and TB screening indicationsLesson 2Special stains and laboratory pathology requests: immunohistochemistry panels (p16, cytokeratins), microbial cultures, fungal stains, molecular testing where indicatedSpecial lab asks to sharpen diagnosis like cell markers, germ grows, fungus colors, gene tests, when to ask, how results affect outcome and treatment.
Selecting appropriate immunohistochemistry panelsMicrobial and fungal cultures from oral lesionsPAS, GMS, and other special histologic stainsMolecular tests for HPV and driver mutationsCommunicating clinical questions to pathologyLesson 3Ultrasound for superficial soft-tissue and lymph node assessment: technique and limitationsSound wave scans for near skin mouth neck parts, how to do, gland looks, blood flow check, limits like person doing it and deep air areas.
Ultrasound equipment and probe selectionTechnique for cervical lymph node scanningSonographic criteria of malignant nodesUse of Doppler in vascular assessmentLimitations and indications for further imagingLesson 4Advanced imaging: when to order contrast-enhanced CT of the mandible, cone-beam CT (CBCT) vs medical CT, and MRI for soft-tissue extent and perineural spreadPicking scans for jaw soft parts, CBCT vs body CT, when dye jaw CT, MRI for soft spread and nerve ways.
Indications for contrast‑enhanced mandibular CTCBCT vs medical CT: strengths and limitationsMRI protocols for soft‑tissue and marrow diseaseImaging signs of perineural tumor spreadRadiation dose, safety, and consent issuesLesson 5Fine-needle aspiration (FNA) and core biopsy of suspicious intraoral or cervical lymph nodes: technique and diagnostic yieldSmall needle suck and thicker cut for worry mouth neck glands, when, how, avoid problems, what it finds, use results in full check.
Indications for FNA vs core biopsyNeedle selection and guidance methodsStepwise FNA technique and smear preparationComplications and how to prevent themInterpreting cytology and adequacy reportsLesson 6Interpreting pathology reports: grades, margins, perineural/lymphovascular invasion, and implications for stagingReading lab reports on sores, levels, edges, nerve vessel spread, gland status, turn to stage and plans.
Tumor type, grade, and differentiationMargin status and clinical significancePerineural and lymphovascular invasionNodal involvement and extranodal extensionCorrelating pathology with TNM stagingLesson 7Stepwise clinical investigations: complete oral exam checklist, vital signs, focused neurological exam, dental status evaluationFull patient check steps in mouth study, outside inside mouth, body signs, nerve quick check, teeth state to find sickness and pick tests.
Pre‑visit history and red‑flag symptom screeningRecording vital signs and systemic risk assessmentStructured extraoral and cranial nerve screeningSystematic intraoral soft‑tissue inspectionDental charting, occlusion, and periodontal statusLesson 8Biopsy planning: incisional vs excisional biopsy—selection criteria for a 1.5 cm tongue lesionPlanning cut for 1.5 cm tongue sore, part cut vs full cut, by sore look, patient, cancer rules for safe way keeping treatment choices.
Clinical assessment of a 1.5 cm tongue lesionCriteria favoring incisional biopsyCriteria favoring excisional biopsyAvoiding distortion of future resection marginsPatient counseling and consent pointsLesson 9Biopsy technique for lateral tongue: surgical approach, margin selection, hemostasis, specimen handling, orientation, and submission for histopathologySide tongue cut method, check sore, plan cut, pick edges, numb, stop bleed, handle sample, mark sides, fix label for best lab read, less problems.
Pre‑biopsy assessment and contraindicationsAnesthesia, traction, and field exposureIncision design and margin selectionHemostasis, suturing, and postoperative careSpecimen orientation, labeling, and transportLesson 10Indications and timing for PET-CT or CT chest in suspected malignancy for staging and metastasis screeningWhen to get full body heat scan or chest CT for worry cancer, stage aims, find far spread, time with cut surgery, how changes team plans.
Oncologic indications for PET‑CT referralRole of CT chest in metastasis screeningOptimal timing within staging workflowCommon pitfalls and false‑positive findingsImpact on TNM staging and treatment plansLesson 11Plain radiography: indications and interpretation of panoramic radiograph (OPG) for jaw pathologyWide jaw x-ray when and how to read for sickness, place patient, normal parts, common problems, limits need more scans.
Indications for ordering an OPGPatient positioning and artifact avoidanceRecognizing normal panoramic anatomyRadiographic features of common jaw lesionsLimitations of OPG and need for CT or CBCT
