Abstract: The factors responsible for the longevity and aesthetics of a restoration are intimately linked to the gingival and periodontal tissues. The placement of any restoration placed in close proximity to the gingival tissues requires adequate access and isolation, for which various gingival retraction methods and materials are available. These are classified broadly as mechanical, chemo-mechanical, cordless and surgical techniques. This review focuses on the rationale behind gingival retraction and a discussion of the newer modalities developed in this regard. CPD/Clinical Relevance: In clinical practice, a wide variety of procedures require the retraction of gingival tissues. Therefore, the clinician must be familiar with the various methods that can be employed to achieve gingival retraction in different clinical scenarios.
