Dentition Analysis Systems
- Dentition analysis is used in orthodontics to measure teeth and jaws.
- It helps understand arch space and predict malocclusion.
- Example systems of dentition analysis include:
- Distance between the tip of the cusp from canine to canine.
- Arch length, measured from the line perpendicular to the mesiobuccal cusp tips of the first permanent molars to the midpoint between the mesioincisal points of the central incisors.
- Arch perimeter, measured from mesial contact of a permanent molar on one side to the mesial contact of permanent molar on the other side, with the line connecting the buccal/incisor tip points in the intervening teeth.

Littles Irregularity Index
- Littles Irregularity Index is a method used in dentition analysis.
- It measures irregularity in the alignment of teeth.
- It helps assess the need for orthodontic treatment.
- The index is calculated by measuring the distance between contact points of adjacent teeth.
- It provides a numerical value to quantify dental irregularities.

Bolton Analysis
- Bolton analysis is another dentition analysis method.
- It evaluates tooth size discrepancies.
- It helps determine the need for interproximal reduction or tooth extraction.
- The analysis compares the ratios of tooth sizes in the upper and lower dental arches.
- It provides information on the proportionality of tooth sizes.

Management of Space Problems in Primary and Mixed Dentitions
- Space problems in primary and mixed dentitions refer to inadequate space for permanent teeth to erupt.
- It is a common concern in orthodontics.
- Various treatment approaches can be used to manage space problems.
- Early intervention is often recommended to prevent severe malocclusion.
- Management may involve space maintainers, arch expansion, or extraction of primary teeth.
