Surgical Techniques for Treating RT2-Associated Gingival Recession: A Randomized Controlled Clinical Trial

INTRODUCTION The treatment of RT2-related gingival recession remains a complicated and evolving mission in periodontal surgery [1]. Recession Type 2 (RT2) is defined as gingival recession characterized by loss of interproximal attachment. The interproximal attachment loss was less than or equal to the buccal attachment loss (measured from the buccal CEJ to the depth of the buccal pocket) [1]. This poses demanding situations for oral hygiene and influences the quality of life through compromising aesthetics [2]. The Cairo classification categorizes recession based mainly on interdental CAL measurement [1]. RT2 recessions are particularly difficult, lacking attached gingiva between the tooth and exhibiting bone loss, complicating whole root coverage. Gingival recession results from elements like periodontitis, trauma from brushing, orthodontic treatment, thin gingival phenotype and aberrant frenal attachment [3,4]. Exposed roots compromise aesthetics, and cause caries, and hypersensitivity issues. Losing attached gingiva compromises the periodontium's protective barrier, increasing susceptibility to further recession and disease [2]. Class III recession beyond the mucogingival junction with interdental tissue/bone loss. This kind was proved complicated to deal with completely because of inadequate interdental papillae for tissue regeneration [2].
