Evaluation of CPP-ACP Prophylactic Effect on Enamel Surface During Orthodontic Treatment

Evaluation of the Demineralizing Effect on Enamel Surface During Orthodontic Treatment With and Without the Addition of Casein Phosphopeptides-Amorphous Calcium Phosphate (CPP-ACP) on: A Randomized Clinical Trial, Split Mouth Design

This study is aiming in preventing the formation of WSL associated with orthodontic treatment which occurs to more than 50% of orthodontically treated patients through applying CPP-ACP on the enamel surface once every 2 weeks for 3 months.

CPP-ACP will be applied on premolars to be extracted in orthodontic patients whose treatment plan indicates extraction of at least 2 premolaes of the maxillary arch. Application will continue on one premolar either the right or left one once every 2 weeks for the first 3 months of the treatment.

Inclusion Criteria:

• medically free
• molar classification class II
• Canine classification class II

Exclusion Criteria:

• spacing of teeth
• Decreased overjet
• Molar classification III Medically compromised patients
• pregnant females
