Noncarious cervical lesions (NCCL)--a clinical concept based on the literature review. Part 2: restoration

To present an updated knowledge on the restorative options and their performance in the particular environment of non-carious cervical lesions (NCCL).Evidence-based support for a proper restoration of NCCL was searched. For this purpose, literature over the last 10 years available in the MEDLINE database was reviewed. Previous systematic reviews, meta-analysis and clinical trials as randomized clinical trials with a testing period of minimum 1 year were selected.Until recently, glass-ionomer-based materials were considered the treatment of choice in most of the NCCL, although consistent improvements are still required. Today, based on the excellent esthetic properties and the good clinical performance, there is a general indication to use composite in NCCL. Clinical behavior was found to be highly product-dependent. The choice of an adhesive with tested efficiency is decisive for the retention and marginal adaptation, whereas differences in flexibility were not found to be clinically important. A periodontal-esthetic approach was suggested by combining the surgical root coverage with the correction of the emergence profile by composite.
