Study Notes

Odontograms Charting

  • A blue pen is used to record most findings on an odontogram.
  • A red pen specifies conditions that require treatment.
  • Red marks are made for carious lesions, overhanging margins, fractures, periapical abscesses, and some periodontal pockets.
  • Count the number of teeth present before beginning charting.
  • Charting involves 11 circuits: missing teeth, occlusion, abnormal tooth surfaces, mobility, percussion, gingival abnormalities, decayed, replaced, and fractured teeth, contact points, vitality, radiographs, and lab tests.
  • Maxillary lateral incisors and mandibular second bicuspids are the most frequently absent teeth, aside from permanent third molars.
  • When examining for missing or misplaced teeth, note endentulous areas, tipped, rotated, supernumerary teeth, and impacted teeth.
  • Incomplete eruption of teeth is recorded with a blue pen on the facial aspect only.
  • Over eruption is also recorded with a blue pen on the facial aspect.
  • Unerupted quadrants are documented in blue pen on both facial and lingual aspects.
  • Partially erupted quadrants are indicated in blue pen on facial and lingual aspects.
  • Vertical impacted teeth are recorded with a blue pen on both facial and lingual aspects.
  • Horizontal impacted teeth are noted in blue pen on facial and lingual aspects.
  • Mesio-angular impaction is documented using a blue pen on facial and lingual aspects (root area).
  • Distoangular impaction is recorded in blue pen on facial and lingual aspects.
  • Buccal and lingual impactions are marked in blue pen on facial and lingual aspects, with an arrow on the occlusal.
  • Supernumerary teeth are indicated on the facial aspect using a blue pen and determined radiographically.
  • When a space maintainer is present, document it with a blue pen on the occlusal aspect, noting unerupted primary teeth in the case.
  • Rotated teeth are charted with a blue pen on the occlusal aspect.
  • Buccal/lingual version of teeth is noted with a blue pen on the occlusal aspect.
  • Tipping of teeth is recorded in blue on the facial aspect.
  • Drifting of teeth is charted with a blue pen; circle the missing tooth and create an arrow pointing to the empty space on the facial aspect.

Facial Profiles

  • The orthognathic profile presents a straight facial alignment, with the NABP plane perpendicular to the Frankfort plane and normal position of the mandible relative to the cranium.
  • Facial profiles can be categorized into three types: orthognathic, retrognathic, and prognathic.
  • The retrognathic profile has an NABP angle less than 90 degrees, characterized by a retruded mandible and a convex appearance due to the prominence of the lip.
  • The prognathic profile demonstrates an NABP angle greater than 90 degrees, with a protruded mandible leading to a concave appearance from a prominent chin.

Classes of Occlusion

  • Class 1 occlusion is considered ideal, characterized by normal lip and tongue function and a straight facial profile.
  • In Class 1 malocclusion, the maxillary first molar cusp articulates with the mandibular first molar groove, with minimal overjet (OJ) and overbite (OB).
  • Class 2 malocclusion features a retrognathic profile with a prominent maxilla or retruded mandible, resulting in a convex facial appearance.
  • Occlusal profile of Class 2: The maxillary first premolar cusp interacts with the mandibular first molar's mesial embrasure, with maxillary cuspid and bicuspid occluding ahead of their mandibular counterparts.
  • Class 1- division 0 shows normal inclination of maxillary incisors with minimal facial profile distortion.
  • Class 2- division 1 involves maxillary incisors in labioversion leading to a pronounced overjet, creating a dramatic convex facial profile.
  • Class 2- division 2 occurs when the central maxillary incisors are in linguoversion, potentially resulting in a substantial overbite with little overjet.
