Gingival recession, also known as 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.[1] Gum recession is a common problem in adults over the age of 40, but it may also occur starting from the age of a teenager, or around the age of 10. It may exist with or without a concomitant decrease in crown-to-root ratio (recession of alveolar bone)


Various classifications have been proposed to classify gingival recession, Miller’s classification system. Being the one that is most widely followed. Many cases which are encountered in daily clinical practice cannot be classified according to the criteria of the present classification systems. Kumar & Masamatti’s classification system gives a comprehensive depiction of recessive defect that can be used to include cases that cannot be classified according to present classifications. A separate classification system forpalatal recessions (PR) have been given. A new comprehensive classification system classifies recession on the basis of the position of Interdental papilla and buccal/lingual/palatal recessions. Kumar & Masamatti’s classification system tries to overcome the limitations of Miller’s classification.
