Introduction: The gingival papilla, also known as the interdental papilla, is the triangular portion of gum tissue that occupies the space between two neighboring teeth. In the anterior region, papillae typically appear more pyramidal, while in the posterior they tend to be more blunted. Its shape and height are determined by factors such as the position of the contact points and the underlying bone structure. When the papilla is absent, it creates a “dark triangle”, which can lead to esthetic issues, increased root sensitivity, and a greater risk of plaque accumulation.
Aim of the study: The purpose of the study involves highlighting the minimum invasive reconstruction techniques using the hyaluronic acid for papilla regeneration.
Material and Methods: This article aimed to provide a comprehensive review of the recent techniques used in minimally invasive procedures for papilla regeneration. Relevant literature was identified through a search of electronic databases, including PubMed, ResearchGate, and Google Scholar using the following keywords: “interdental papilla regeneration”, “hyaluronic acid”, “minimally invasive treatment”.
Results: The initial literature search yielded 114 articles. Later a step-by-step selection process was carried out based on clear inclusion criteria. Free-full text versions of the selected articles were then reviewed in detail to ensure they met the inclusion criteria. Based on the analysis performed, 11 articles extracted from literature were used in the present study.
Conclusions: Within the constraints of this study, the application of a commercially available hyaluronic acid (HA) gel for treating interdental papillary deficiency appears to be both effective and promising. However, the current body of evidence is still limited, with few high-quality clinical trials conducted on this technique. Future studies should address larger sample sizes, optimal HA concentrations, and standardized injection protocols to better assess its long-term efficacy and safety.
