The challenges of composite restorations of non-carious cervical lesions

Although the restoration of non-carious cervical lesions (NCCLs) may seem straightforward, it is the restorative therapy with the highest rate of clinical failure. This may be due to marginal discolouration, fracture or loss of the restoration, the appearance of secondary caries or aggravation or the creation of periodontal problems. In view of this, it is essential to take into account the difficulties in achieving these restorations and addressing these by choosing the most suitable materials and techniques. This review summarizes the current understanding of restorative management of NCCLs with composite resin and discusses factors affecting efficacy and difficulties encountered during the implementation in order to propose an approach that leads to a higher success rate and longevity of the restoration. CPD/Clinical Relevance: Choosing a protocol that achieves a high success rate for the restorative management of NCCLs with composite resin is important.
