Introduction: Bonding is a technique sensitive procedure that greatly affects
the success of orthodontic treatment. Moisture contamination is regarded as the
most common cause of bond failure. In this study a comparison was made between
hydrophobic and hydrophilic adhesives in both dry and wet fields.
Aim: The objective of this investigation was to assess the impact of moisture
contamination on SBS of hydrophilic adhesives in comparison to that of a conventional
hydrophobic adhesive in dry and wet fields. Materials and methods: Sixty sound
premolars were split into three equal groups. Group I was bonded using conventional
adhesive (Contec LC), Group II was bonded using hydrophilic adhesive (Transbond
Plus Color Change), and Group III was bonded with hydrophilic RMGI (Meron
Plus AC). Based on the bonding field, each group was thereafter separated into two
subgroups (wet or dry). After bonding, a universal testing equipment was used to assess
the SBS. Results: Although saliva affected Contec LC more than it affected Transbond
Plus Color Change or Meron Plus AC, this was not statistically significant (P= 0.228).
Conclusion: Hydrophilic adhesives did not provide any significant advantages over
conventional adhesives in either wet or dry fields.
