Study Notes
Extraoral and Intraoral Examination
- Systematic examination is crucial for total patient care, addressing physical, mental, and psychological health.
- Regular assessments should occur at each continuing care appointment, including risk factor evaluations.
Types of Examinations
- Complete: Comprehensive assessment including all components.
- Screening: Brief preliminary exam often for pain relief.
- Limited: Quick exam for acute situations.
- Follow-up: Evaluation of healing post-treatment.
- Continuing care: Complete reassessment after care completion to create new diagnoses and care plans.
Examination Methods
- Visual: Direct observation, radiographic, and transillumination techniques.
- Palpation: Digital, bidigital, bimanual, and bilateral methods for assessment.
- Instrumentation: Use of periodontal probes and explorers.
- Percussion: Tapping surfaces to evaluate response or sound.
- Electrical testing: Determines presence of vital pulp tissue.
- Auscultation: Listening to sounds for diagnosis.
Signs and Symptoms
- General signs may indicate varied diseases; pathognomonic signs are unique to specific conditions.
- Signs: Objective abnormalities identified by professionals.
- Symptoms: Subjective reported changes indicative of conditions.
Preparation for Examination
- Review health histories and medical records, including risk factors and radiographs.
- Explain procedures and their significance to the patient.
Rationale for Examinations
- Early identification of abnormalities, including oral cancer.
- May reveal signs of various systemic disorders such as thyroid issues, nutritional deficiencies, and sexually transmitted diseases.
Anatomical Landmarks of the Oral Cavity
- Normal anatomy comprehension is essential to recognize abnormalities.
- Oral mucosa consists of connective tissue covered by stratified squamous epithelium with three types.
Types of Oral Mucosa
- Masticatory Mucosa: Keratinized, covers gingiva and hard palate; firmly attached.
- Lining Mucosa: Non-keratinized, covers inner lips, cheeks, floor of mouth, and soft palate; loosely attached.
- Specialized Mucosa: Contains papillae on the tongue, aiding in taste sensation.
Sequence of Examination
- Follow a systematic order starting with extraoral observations (face, skin, eyes) to intraoral observations (mouth, tongue, palate).
Documentation of Findings
- Record lesion history, including duration and previous evaluations.
- Describe location and extent using terms like localized/generalized, single/multiple.
- Document physical characteristics: size, shape, color, texture, consistency.
Morphologic Categories of Lesions
- Elevated, depressed, and flat lesions, each with specific characteristics.
- Elevated lesions may be blisterform (vesicles) or nonblisterform (nodules).
Oral Cancer Overview
- Cancer in the oral cavity can start in squamous cells lining mucosal surfaces.
- Common sites include lateral borders of the tongue, floor of the mouth, and lips.
Early Signs of Oral Cancer
- White patches (leukoplakia), red patches (erythroplakia), ulcers, or unusual masses.
Clinical Recommendations
- Conduct updated histories and examinations for adults, monitoring even non-suspicious lesions.
- Biopsy suspicious lesions; perform cytologic tests when biopsies are refused.
Biopsy Protocol
- Considered the definitive method for diagnosing oral cancers.
- Indications include unidentified oral lesions and persistent lesions not healing after two weeks.
Role of the Dental Hygienist
- Identify cancer risk factors and educate patients on tobacco cessation and HPV vaccination.
- Stay updated with continuing education and evidence-based practice guidelines to improve confidence in screening and recommendations.
