Brief Summary:
The aim of this study is to evaluate the addition of new technology of resin modified glass-ionomer in comparison to resin infiltration in treating post-orthodontic white spot lesions; both applies into the same patient's mouth; to reveal which material will have more clinical satisfactory performance inside the oral cavity and to overcome the high expensive cost in treating such clinical cases

Condition or disease Intervention/treatment Phase
White Spot Lesions Drug: Vanish xt Extended Contact Varnish Drug: resin infiltration Phase 2

Detailed Description:

Roles and responsibilities:

  • Shaimaa Mohammed (SH.M.): Operator and author.Specialist in Air-Force Specialized Hospital.
  • Mohamed Riad (M.R.): Main supervisor, data monitoring and auditing, Professor, Conservative Dentistry Department,Cairo University.

A- Preoperative clinical assessment:

  1. Explain patient need toward aesthetic needs
  2. Digital photos for white spot lesions
  3. Recording number of white spot lesions and site. (SH.M.) will apply both materials at the same patient mouth (Split mouth technique) according to the manufacturer's instructions.

    • Intervention: resin modified glass ionomer cement varnish: Vanish™ xt Extended Contact Varnish (3M ESPE Dental)
    • Comparator: resin infiltration (Dental Milestones Guaranteed, Germany).

(A.H) and (SH.M) will assess the outcome measures through the follow up time: immediately after,1 day, 1 week,1 month,3 months, 6 months, 12 months

Arm Intervention/treatment
Experimental: Vanish xt Extended Contact Varnish
Vanish xt Extended Contact Varnish is a resin modified glass ionomer cement and fluoride varnish used to treat white spot lesions to be more resistant to early caries progression.
Drug: Vanish xt Extended Contact Varnish
resin modified glass- ionomer cement varnish applied as a thin layer coating and cured
Other Name: Clinpro xt

Active Comparator: Resin infiltration
Resin infiltration is a low viscous resin infiltrates into small pores of white spot lesions to block entrance of bacteria into dentinal tubules of the tooth and more resistant to early caries progression.
Drug: resin infiltration
low viscous light cure resin applied in layers and cured
Other Name: ICON
