Gingival recession is an apical shift of the gingival margin with exposure of the root surface to the oral cavity. Gingival recession may be present in healthy gingival sulcus with normal interdental crestal bone levels or it may occur in an ailing periodontium with alveolar bone loss. Patients often visit the dentist for treatment of gingival recession due to aesthetic reasons. Other glitches faced by the patients are hypersensitivity due to exposed roots and root abrasion or caries. The definitive objective of a root coverage technique is complete coverage of the recession defect with the gingival tissues in good appearance and harmony with the adjacent tissues after healing.

A study by Addy et al 1999 showed the prevalence of recession to be higher on upper canine and first pre-molar teeth and lower canine, first premolar and incisor teeth, in a group of 92 subjects with a mean age of 35 years.13 Some studies show that the prevalence of gingival recession is higher on the left side of the jaw.14 Higher levels of recession have been found in males than females and in Afrocarribeans and African-american than White Caucasians and other racial or ethnic groups.15 Recession is also found in patients with good oral hygiene as well as in patients with poor oral hygiene. In patients with good oral hygiene, recession is located commonly on buccal surfaces and in those with poor oral hygiene other tooth surfaces are also affected.16,17 Studies also show a correlation between calculus and gingival recession. One such study by Van der Weijden et al 1998 shows a higher prevalence of recession on lingual surfaces of lower anterior teeth in the age group of 20-34 years.18 Habits such as lip and tongue piercings are associated with increased prevalence of recession in mandibular anterior teeth.19 In patients with periodontitis attachment loss, bone loss and gingival recession is located mainly interdentally. It has been estimated that approximately 60% …show more content…
Interproximal bone loss is visible on the radiograph. This is sub-classified into three categories: o Class II-A: There is no marginal tissue recession on F/L aspect o Class II-B: Gingival margin on F/L aspect lies apical to CEJ but coronal to MGJ with attached gingiva present between marginal gingiva and MGJ o Class II-C: Gingival margin on F/L aspect lies at or apical to MGJ with an absence of attached gingiva between marginal gingiva and MGJ
Either of the subdivisions can be on F or L aspect or both (F and L).
• Class III: The tip of the interdental papilla is located at or apical to the level of the CEJ mid-buccally/mid-lingually. Interproximal bone loss is visible on the radiograph. This is sub-classified into two
