NCT05345379

Brief Summary

A single-operator, randomized controlled trial (RCT) will be conducted to evaluate the clinical effectiveness of moisture insensitive primers (MIPs) in bonding molar tubes under moisture contaminated conditions by comparing the clinical bond failure and survival rate of molar tubes using two MIPs which are Transbond ™ MIP (3M Unitek Dental Products, Monrovia, CA, USA) and Assure® Plus-All Surface Light Cure Bonding Primer (Reliance, Itasca, IL, USA).

Eligibility Criteria

Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Patients seeking for metal fixed orthodontic appliance with 0.22"\*0.28";
  • Complete set of permanent dentition with fully erupted molar teeth on both arches;
  • Intact 1st molars and mainly their buccal surfaces are free from caries, fillings, or gingival hyperplasia;

You may not qualify if:

  • Patients with systemic problem or genetic syndrome that affecting enamel surface like patients with generalized enamel hypoplasia.
  • Patients exhibit parafunctional habits;
  • Patients who their treatment plan need appliance that soldered on molar bands.
  • No occlusal interferences that can affect the ideal position of molar tubes, especially in the lower arch.

Masking Details
This trial will be triple-blinded in which neither the participants nor the trial team will know which one of the primers a patient has received, as well as the outcome assessor will be blinded. This can be achieved by placing the two primers in two similar masked bottles and giving them numerical coding i.e. number one and number two coding for either type of primer.

Model Details: The primers will be randomly allocated using a split-mouth, cross-quadrant design. In each patient, two diagonal quadrants (i.e. upper right and lower left, or vice versa) will be randomly assigned to each primer group.
