| Abstract | Objective This in vitro study aimed to assess the color adjustment level of single-shade composites following staining/repolishing and bleaching procedures. Materials and methods Cervical cavities in two depths (1 mm and 2 mm) were restored. Three single-shade composites (Omnichroma, OM; Essentia Universal, EU; and Charisma DiamondOne, CDO) and one group-shade composite (NeoSpectraST, NEO) were used (n = 10 for each). Following the thermal aging, half of the restorations were subjected to staining and repolishing procedures, while the other half were subjected to bleaching procedures. The color adjustments between restoration and adjacent tooth surfaces were assessed. The deemed significance was set at < 0.050. Results According to the initial measurements, the NEO composite presented the lowest ∆E00 while the OM presented the highest (P = .005 and P = .014). Single-shade composites presented similar and clinically acceptable ∆E00 values (P ≥ .050; AT ≤ 1.8). After the staining, the ∆E00 of the OM was higher among the other single-shade composites (P = .001). Repolishing procedure decreased only the ∆E00 of the NEO composite (P = .020). The bleaching procedure provided no difference for the single-shade composites (P ≥ .050). The increase in the cavity depth decreased the initial color adjustments for the OM in both repolishing and bleaching groups (P = .041 and P = .047). Conclusions Re-polishing after aging and staining may not enhance the single-shade composites’ color adjustment level, unlike the group-shade composites. Good color adjustment might be predicted for the single-shade composites after bleaching, unlike the group-shade composites. The effect of the cavity depth was considered composite brand dependent. Clinical significance Clinicians should understand the color adjustment behaviors of the single-shade composites well after different clinical procedures such as staining, re-polishing, and bleaching to perform a proper restorative treatment plan and to obtain better esthetic outcomes. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
