Background: A black triangle or an open gingival embrasure is one of the main problems that compromise esthetics. Different surgical techniques have been utilized to resolve this problem. Consequently, minimally invasive techniques using filler injections have been recommended. Hyaluronic acid (HA), a naturally occurring polysaccharide; was widely used in treatment of deficient interdental papillae. On the other hand, Radiesse is calcium hydroxide dermal filler used in facial rejuvenation. This study was performed to compare the effect of Radiesse and hyaluronic acid gel in treatment of deficient interdental papillae.
Materials and Methods: A total of 30 female patients with 40 deficient interdental papillae were assigned into two groups A and B. Group A received hyaluronic acid gel injection while group B received Radiesse gel injection. Clinical data included papillary marginal gingival index, probing depth, clinical attachment loss, papilla presence index and height of interdental papilla. Data were taken at baseline, after three weeks, three and six months.
Results: Significant improvement occurred in both groups but this improvement was more prevalent in Radiesse group compared with HA group. There was a decline in the papillary height in the HA group after three and six months while in Radiesse group more long-lasting effect was denoted.
Conclusion: It was concluded that both fillers were biocompatible and safe for treatment of interdental papilla deficiency. Though, Radiesse gel was more effective and long-lasting compared with hyaluronic acid.
