Six-month clinical evaluation of fissure sealants placed with different adhesive systems: a randomized controlled trial

26723

OBJECTIVE: To compare the retention and caries formation rates of fissure sealants applied with an etch rinse adhesive system (Adper Single Bond 2) or with an universal adhesive system (Single Bond Universal) used with etch rinse mode or self-etch mode after 6 months. MATERIALS AND METHOD: Non-invasive fissure sealants of 13 patients (19-22 age) were evaluated. The fissure sealant (Fissurit FX, Voco, Cuxhaven, Germany) was placed after three different pretreatment procedure and then polymerized; Group A: 35% phosphoric acid gel + Adper Single Bond 2 (3M ESPE, St Paul MN, USA), Group B: 35% phosphoric acid gel + Single Bond Universal adhesive (3M ESPE, St Paul MN, USA), Group C: Single Bond Universal adhesive. All the materials were used according to the manufacturers’ recommendations. A total of 144 teeth were sealed (n=48 in each group). The retention of fissure sealants and caries formation was evaluated by two calibrated examiners at one week and six month recalls. The evaluation criteria for retention were 1=full retention, 2=partial loss, 3=total loss. Data were analyzed with Pearson chi square test. RESULTS: The recall rate was 100% at the 6-month control. Retention rates at 6-months were as follows: Group A: full retention: 93.75% and total loss: 6.25% of the sealants; Group B: all sealants were recorded to exhibit full retention; Group C: full retention: 29.2%, partial loss: 2.1% and total loss: 68.8% of the sealants. Differences between Group C and the other groups were statistically significant (p 0.001). No caries was detected at the 6-month control. CONCLUSION: Single Bond Universal adhesive used in a selfetch mode showed a clinically low performance
