Intraoral Examination

Overview

  • Focuses on examining both soft and hard tissues in the mouth.
  • Key elements include gingiva, palate, tonsils, frenum, and tongue.

Soft Tissue Examination

Gingiva

  • Examined for:
    • Color
    • Shape
    • Configuration
  • Significance:
    • Important in identifying contraindications for orthodontic treatment in patients with periodontitis or gingivitis.
    • Anterior marginal gingivitis often seen in mouth breathers, due to dryness.
  • Checks for:
    • Ulcerations
    • Atrophy

Tongue

  • Examined for:
    • Shape, which includes variations like long, broad, small.
    • Color
    • Configuration
  • Conditions identified:
    • Macroglossia (extremely large tongue) visible on a lateral cephalogram.
    • Signs include lateral margin of the tongue.
  • Functional checks:
    • Tongue tie deformities
    • Speech impairments
    • Alterations in resting position

Frenum

  • Labial Frenum Examined:
    • Can cause midline diastema
  • Test Used:
    • Blanch Test: Determines if labial frenum causes diastema. In this test, the examiner retracts the maxillary upper lip to check for blanching in the dental area.

Palate

  • Examined for:
    • Ulcerations
    • Scar tissue
    • Cysts
    • Swellings
  • Shape Variations:
    • Brachycephalic patients: Broad shaped palate.
    • Dolichocephalic patients: Long shaped palate.

Tonsils and Adenoids

  • Type: Pair of lymphoid tissues.
  • Examined for:
    • Size variation
    • Inflammation
  • Physiological Aspect:
    • Enlarges during pivotal stages of life.
  • Effects of Inflammation:
    • Alters tongue position downward
    • Mandible moves forward
    • Results in a characteristic facial appearance known as "adenoid facies."
