The procedure for regenerating interdental papilla is complex and technique-sensitive. However, the patient demand to reduce black triangle has dramatically increased in recent years. This article aimed to review the most recent surgical techniques on interdental papilla regeneration by reporting studies published from 2016 to 2021. A literature search was performed in electronic databases, including PubMed, Medline, and Web of Science using the following keywords: “interdental papilla regeneration,” “papillary reconstruction,” “surgical papillary regeneration,” and “hyaluronic acid injection.” Studies that have involved surgical techniques for interdental papilla regeneration as well as less invasive surgical procedure such as hyaluronic acid injections are comprehensively reviewed in this article. Techniques such as tunnelling and coronally advanced flap appear to have better success rate compared to other techniques. In view of graft, connective tissue graft resulted in successful interdental papilla regeneration with papillary fill maintained over long-term compared to concentrated growth factors. A less invasive option would be hyaluronic acid injection, but with less success rate compared to surgical procedures. However, the results were limited by the lack of standardised method to measure successful interdental papilla regeneration. This article comprehensively reviews the updates on interdental papilla regeneration techniques.

The interdental papilla is of utmost importance in smile aesthetics. Missing interdental tissue often raises an aesthetic concern; however, the issue is more than just an aesthetic complication. This study reviews the most commonly seen cases and methods to minimize the aesthetic complications caused by missing interdental tissue. The technique that will be discussed is from nonsurgical techniques, including composite restoration, indirect restorations, and gingival veneer. This article is clinically relevant in educating clinicians on various methods to restore and improve the optics that arise from a missing interdental papilla.

Nowadays, there are countless latest comprehensive studies done on the subject of tooth whitening for different discolouration challenges available coming out each year. The objective of this study is to provide an insight and guide to different tooth whitening modalities, their indications and potential side effects to ensure optimum treatment planning. The Scale for the Assessment of Narrative Review Articles (SANRA) is used as a guide for the articles chosen. Articles were searched in PubMed/Medline to identify relevant articles using the combination of search terms: teeth whitening, whitening toothpaste, tooth discolouration with a combination of each discolouration challenge. The literature retrieved was then narrowed down only for teeth whitening that corresponds to causative factors and the repeated and similar types of treatment were eliminated. A comprehensive literature search was conducted on PubMed and Scopus databases. A separate search was made on a Google search engine. The references from the reviewed material were used to locate other relevant publications. Different discolouration challenges will affect the final outcome of the treatment. It is vital for dentists to have knowledge of tooth whitening modalities available and their specific indications and limitations. Tooth whitening procedures are a minimally invasive way to improve dental aesthetic, conservatively.
