The following are the classifications for gingival recession. Gingival Recession is a common problem 1. Sullivan and Atkins (1968) associated with or without Periodontitis.

[3] for Gingival Recession, Palatal recession INTRODUCTION Gingival recession is defined as an apical shift of the gingival margin (GM) from its position 1 mm coronal to or at the level of the cemento-enamel junction (CEJ) with exposure of the root surface to the oral environment. [1] The displacement of marginal tissue apical to the cemento- enamel junction (CEJ). [2] The term “marginal tissue recession” has been considered to be more accurate than “gingival recession,” since the marginal Figure 1: Sullivan & Atkins Classification tissue may have been what is known as alveolar mucosa.
