Gingival Retraction Clinical Trial
Official title:
Assessment of Technique Sensitivity and Gingival Health in Management of Cervical Lesions Performed Using Subgingival Clamp Versus Retraction Cord: A Randomized Controlled Clinical Trial
assessing subgingival clamp in handling and retracting the gingival tissue at the cervical area to see its effect on the gingival health and its technique sensitivity compared to the most commonly used method (retraction cord), as gingival displacement for cervical restorations affects smile and therefore patient satisfaction with the result.
Gingival displacement for restoring cervical lesions using retraction cord or subgingival
clamp with their technique sensitivity affects the smile as they may cause gingival bleeding,
laceration or recession and therefore affects patient satisfaction. There are several methods
to achieve retraction; retraction cord is the most commonly used method. It controls the soft
tissue displacement, gingival bleeding and expose the margins which provide good
visualization and access.
They are effective and safe if the gingiva is healthy, also inexpensive retraction method.
However, the use of retraction cord has some disadvantages like: it is time consuming, may
cause gingival recession after healing and bleeding after removal, its application needs
practice and skill as improper handling of the cord can cause traumatic injuries, gingival
recession and marginal exposure of the restoration, it may cause postoperative discomfort and
pain for the patient and finally leaving the retraction cord for long time or forgetting to
remove it from the sulcus can cause permanent damage to the gingival tissue.
Using gingival retracting clamps with rubber dam isolation prevent the gap caused around the
teeth due to vertical and horizontal tissue displacement occurred beneath the area of
dento-gingival attachment upon the application of the retraction cord. Also, after clamp
stabilization in position, it prevents accidental slippage and trauma to surrounding soft
tissue during the restorative procedure. They also provide maximum tissue retraction without
laceration of gingival tissues. Also, their availability in different sizes and shapes
provide a good adaptation to any tooth configuration and any inaccessible area.
