The anterior ratio is known to be 77.2%. An overall ratio of more than 91.3% means that the mandibular teeth are bigger when compared to normal. A ratio smaller than 91.3% would mean the mandibular teeth are smaller than normal. Anterior analysis follows the same principle. Having a different ratio than normal is referred to as Bolton Discrepancy.
The aim when creating the index was to allow for a system in measuring occlusion which can be easily comparable. The five major groups which are recorded are as follows: 1. Gross Anomalies 2.Dentition: absent teeth, supernumerary teeth, malformed incisors and exotic eruption 3.Spaced condition: Diastema, Crowding and Spacing 4.Occlusion:
This spacing is important as it allows space for the permanent (adult) teeth to erupt into the correct occlusion, and without this spacing there is likely to be crowding of the permanent dentition. In order to fully understand the development of occlusion and malocclusion , it is important to understand the premolar dynamics in the mixed ...
Mesiodens: Mesiodens is an extra tooth that grows behind the front teeth. A mesiodens may push the front teeth apart to make room for itself thus creating a gap between the front teeth. [3] 4. Skeletal discrepancy: Dental skeletal discrepancy can be a cause behind gap teeth. If the upper jaw grows more than the lower jaw, teeth on the upper jaw ...
Dentition analyses are systems of tooth and jaw measurement used in orthodontics to understand arch space and predict any malocclusion (mal-alignment of the teeth and the bite). [1] Example systems of dentition analysis are listed below.
The system uses two numbers to define each tooth. One to specify the quadrant, and one to specify the tooth within that quadrant. Orientation of the chart is traditionally "dentist's view", i.e. patient's right corresponds to notation chart left. The designations "left" and "right" on the chart below correspond to the patient's left and right.

The Palmer notation consists of a symbol (⏌⎿ ⏋⎾) designating in which quadrant the tooth is found and a number indicating the position from the midline. Adult teeth are numbered 1 to 8, with deciduous (baby) teeth indicated by a letter A to E.
