The study aims to evaluate the effect of using PRF and vitamin Dꝫ injections on periodontal health and parameters and compare them when used to facilitate orthodontic treatment.
* Participants will be recruited from the Faculty of Dentistry, Beni-Suef University. All subjects will be informed of the treatment procedures and will sign a consent form. * Subjects will be randomly divided into two groups: Group 1 (PRF group): upper canine retraction will be facilitated by PRF injection that will be randomly assigned to one side (experimental side). The contralateral side will serve as the control one. Group II (Vitamin Dꝫ group): canine retraction will be facilitated by Vitamin Dꝫ injection that will be randomly assigned to one side (experimental side). The contralateral side will serve as the control one. * The predicted sample size (n) was a total of (28) cases (i.e. 14 cases per group). Sample size calculation was performed using G\*Power version 3.1.9.7 * Simple randomization will be designed with the aid of a computer-generated schedule with 1:1 allocation ratio. Allocation concealment will be achieved using identical opaque, sealed envelopes. Randomization and allocation concealment will be performed by one of the academic staff who will not be involved in the study and will keep the allocation table away from the operators. The operator will shuffle the sealed envelopes and will ask the patient to pick one envelope at the time of recruitment. In each group, a randomly selected side will act as the experimental side while the contralateral side will serve as the control. Blinding of the operators will not be applicable and so blinding will be limited to the outcome assessment. Methodology: * All patients will be treated with a 0.022-inch MBT bracket system. Leveling and alignment phase will be completed until a 0.017 X 0.025''stainless steel wire will be inserted passively into the bracket slot. Before canine retraction, the subject will be randomly assigned to one of the groups (PRF or Vitamin Dꝫ group). In both groups, canine retraction will be performed with closed Ni-Ti coil springs with a force of 150 g per side that will be adjusted by the use of a force gauge.

RECRUITINGEvaluate the effect of using PRF and Vitamin Dꝫ injections on periodontal health and compare them.
Clinical periodontal examination of the upper canines will be done before and after retraction on the experimental and control sides by recording the probing depth (PD). • The probing depth will be measured from the gingival margin to the base of the gingival sulcus in millimeters by using a manual periodontal probe (William's probe). The measurements will be recorded at 6 sites around the tooth.
Time frame: 3 - 4 months
Investigate the effect of PRF and Vitamin Dꝫ injections on the gingival thickness.
The gingival thickness will be recorded using an endodontic file with a stopper, which is placed horizontally, perpendicular to the long axis of the tooth on the labial gingiva.
Time frame: 3 - 4 months
