Dentinal hypersensitivity commonly occurs in patients with gingival recession, resulting from a reduced periodontium or in patients who have undergone non-surgical and surgical periodontal therapy (Pradeep 2010, Yilmaz 2011). When the gingiva recede, the root surfaces of the teeth are exposed (West 2008). In addition, after a non-surgical or surgical periodontal procedure, the cementum of the root surface is removed as a result of scaling and root planing. This leaves dentin exposed on the root surface with open dentinal tubules. In addition, dentin is less mineralized than enamel and has a greater susceptibility to and a faster progression of root caries and dentinal hypersensitivity (Saunders 2005). Root caries commonly occurs in patients who have undergone periodontal therapy and extensive root caries often results in the extraction of the tooth (Hull 1997).
