A 3-year clinical study of a hybrid composite resin as fissure sealant and as restorative material for Class i restorations
Stadtler
After 3 years, 78.0% of 64 reexamined fissure restorations (extended sealants) and small occlusal restorations were clinically acceptable or excellent, and 21.9% had to be repaired or replaced because they had fractured (6.3%) or were o longer clinically acceptable by some other criterion (15.6%). The conservative preventive resin restorati on seems to be an effective treatment for small occlusal defects. Meticulous dental hygiene by the patient and regular examinations by the dentist are mandatory.
