Tooth mobility is the horizontal or vertical displacement of a tooth beyond its normal physiological boundaries [1] around the gingival (gum) area, i.e. the medical term for a loose tooth. Tooth loss implies in loss of several orofacial structures, such as bone tissues, nerves, receptors and muscles and consequently, most orofacial functions ...
As a general rule, mobility is graded clinically by applying firm pressure with either two metal instruments or one metal instrument and a gloved finger. [4] Normal mobility Grade I: Slightly more than normal (<0.2mm horizontal movement) Grade II: Moderately more than normal (1-2mm horizontal movement)
Wisdom teeth are not included because pericoronitis and tooth impaction may cause isolated periodontal defects which do not represent the general periodontal condition of the rest of the mouth. At least 2 teeth must be present in a sextant for it to be scored. If only 1 tooth is present in a sextant, the tooth is included in the adjoining sextant.
However, while this index is simple, easy and able to provide prevalence and incidence data in populations group, there are some major disadvantage with this index: primary dentition, erupting teeth and missing teeth are left out in the scoring system and difficulties in judging conformity of each tooth to an ideal position in all planes.
1: Total loss of attachment (clinical attachment loss, CAL) is the sum of 2: Gingival recession, and 3: Probing depth. Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth.

The tip of the instrument is placed with light pressure of 10-20 grams [1] into the gingival sulcus, which is an area of potential space between a tooth and the surrounding tissue. It is important to keep the periodontal probe parallel to the contours of the root of the tooth and to insert the probe down to the base of the pocket. This results ...

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.
