Gum recession can start early in life, with \\~27% of people 15-25 years experiencing recession. The frequency of gum recession increases with age, with 70.3% of adults 45-60 years and \\~100% of adults will experience gum recession in their lifetime.\n\nRecession of the gums is defined as the shift of the marginal gingiva from its normal position on the crown of the tooth to the levels on the root surface beyond the cemento-enamel junction.\n\nWhereas many dental conditions go unnoticed by patients, gum recession can often be visible to patients and for which they may seek advice of a dentist. Gingival recession of the front teeth usually creates an aesthetic problem and anxiety about tooth loss due to progression of the destruction.\n\nGum recession may also be associated with dentin hypersensitivity, root caries, abrasion and\u002For cervical wear, erosion because of exposure of the root surface to the oral environment and an increase in accumulation of dental plaque.\n\nGum recession may be caused by a variety of factors, including but not limited to smoking, hormonal changes, genetics, periodontal disease or insufficient dental hygiene. Treatment for gum recession includes a deep cleaning, dental bonding, antibiotics and surgery.\n\nCalcium hydroxylappetite (CaHA; Radiesse, Merz Aesthetics, Raleigh, NC) is FDA cleared as a facial implant for volume improvement for moderate to severe wrinkles and folds such as the nasolabial folds. CaHA is also cleared by the FDA to fill and\u002For augment dental defects, including periodontal defects.\n\nRadiesse is composed of synthetically produced, smooth and uniform calcium hydroxide microspheres suspended in carboxymethylcellulose gel in ratio 30% microspheres to 70% gel by volume. Radiesse(+) and is the same formulation as Radiesse with the addition of lidocaine in powder format, which reduces pain of injection.\n\nThe CaHA in Radiesse\u002FRadiesse(+) is biocompatible and possess a low risk of stimulating an immune response. Studies have shown that CaHA is an effective collagen and elastin stimulator as well as a robust filler for soft tissue augmentation. CaHA has recently been shown to improve gum recession with results that lasted 6 months and up to 12 months6, as well as resulted in a reduction in gum hypersensivity.",[19,20,21,22],"Gingival Recession, Generalized","Gingival Recession Generalized Moderate","Gingival Recession Localized Moderate","Tooth Sensitivity",[24,25,26,27,28,29],"Gingival recession","Tooth sensitivity","Recessed gums","Gum recession","Attached gingiva","Attached gingiva deficiency","INTERVENTIONAL","TREATMENT",[33],"NA",{"count":35,"type":36},500,"ESTIMATED",[38],{"type":39,"name":40,"description":41,"armGroupLabels":42},"DEVICE","Calcium hydroxylapatite","This intervention consists of calcium hydroxylapatite injections into the attached gingiva of a patient who has gingival recession to stabilize, grow and reverse gingival recession.
