Management of black triangle of interdental papilla using injectable carboxymethyl chitosan hydrogel with and without hyaluronic acid gel (Comparative Study)

Abstract

Open gingival embrasures or-Black triangles‖ are created due to incomplete fill of interdental papilla. (1). Aim of the study: To compare the effect of hyaluronic acid gel alone versus hyaluronic acid gel combined with carboxymethyl chitosan hydrogel In the Management of the black triangle of interdental papilla. Patients and methods: 40 deficient dental papilla sites that were randomly assigned into two equal groups. Group (A) using hyaluronic acid gel only. Group (B) using carboxymethyl chitosan hydrogel with hyaluronic acid gel. Following parameters will be evaluated before treatment and recorded at baseline and after 6 months Plaque index (PI), Bleeding index (BI), Gingival recession (GR), Probing depth (PD), Clinical attachment level (CAL), and height of the black triangle. Results: Both groups showed improvement in clinical parameters although they are statistically insignificant. Upon comparing the results of both treatment modalities, No statistically significant difference was detected regarding BI, PI, PD, CAL, or GR scores along the whole studied period with a p-value>0.05. Conclusion: treatment of black triangle of interdental papilla using injectable carboxymethyl chitosan hydrogel and hyaluronic acid gel show more improvement in clinical outcomes. The reduction of the black triangles after 6 months was not statistically significant between both groups.
