Effect of Different Bonding Techniques on Marginal Adaptation of Harmonize Composite Resin at Different Storage Times
AIM: The aim of this study is to evaluate the outcome of diverse bonding methods on marginal adaptation of harmonize composite at altered times of storage. MATERIALS AND METHODS: The study was done on 120 upper premolars with two adhesive systems (n = 60), self-etch, and total-etch type. Sixty teeth...

description | AIM: The aim of this study is to evaluate the outcome of diverse bonding methods on marginal adaptation of harmonize composite at altered times of storage. MATERIALS AND METHODS: The study was done on 120 upper premolars with two adhesive systems (n = 60), self-etch, and total-etch type. Sixty teeth of each method were stored at three different times (n = 20) 1 day, 3, and 6 months. Class II cavities were made in all teeth restored with Harmonize composite incrementally. Then, each tooth was sectioned into two halves in buccolingual direction and observed with stereomicroscope for detecting any gaps and scanning electron microscope to assess resin-dentin junction. RESULTS: Mean gap area was more in the self-etch group at the cervical and occlusal margins. Storage period of 6 months revealed significantly highest mean gap area. CONCLUSIONS: Total-etch system showed better marginal adaptation than the self-etch system and storage of resin in water has unfavorable marginal adaptation. |
