Introduction:

The degree of microleakage in glass ionomer and nanoparticulated composite resin in non-carious cervical lesions is of great importance for choosing the most suitable restorative material for each clinical case.

Objective:

To describe the degree of microleakage in glass ionomer and nanoparticulated composite resin in non-carious cervical lesions.

Methods:

A literature review, corresponding to the exploratory level, was carried out to answer five scientific questions on the subject. Sixty-two articles were identified from Academic Google or Scopus databases between 2015 and 2022.

Results:

The studies consulted suggest that nanoparticulated composite resin is an effective and esthetic restorative option in dentistry, especially in cases of cavities with high mechanical load and dental esthetics. The case studies reviewed demonstrate that the degree of microleakage in non-carious cervical lesions can be significantly higher in glass ionomer restorations compared to nanoparticulated composite resins.

Conclusions:

It is concluded that the fundamental element in treatment is to carry out a correct diagnosis, determining the needs to improve dental health and to carry out correct planning, so it is necessary to know the different types of treatments with the aim of selecting the most suitable one, which complies with the biological, mechanical and esthetic characteristics, since one of the fundamental objectives of any treatment is to restore function and esthetics in a satisfactory way and with the greatest possible durability.
