Overview

EVALUATION OF EFFICACY OF LOCALLY INJECTED Vitamin D3 (calcitriol or 1.25 dihidroxicolecalciferol) IN ACCELERATING ORTHODONTIC MOVEMENT Design: A randomized, controlled, crossover, double-blind clinical study including Eighteen adult , aged 15-25 years old.

The rate of orthodontic tooth movement depends on two general factors: the forces used in order to cause orthodontic tooth movement and respectively the individual (biological) response of the body to these forces. There are many methods for accelerating orthodontic tooth movement. but, every method has its disadvantages, such as pain and root absorption. Locally injected of vitamin d3 was proposed to accelerates tooth movement with minimal disadvantages, but there aren't enough clinical studies to prove this claim.

Outcomes

Primary Outcomes

Primary Outcome Measure was the overall time needed to complete leveling and aligning (OLAT) the mandible dental arch

To calculate outcome measures, a mandible alginate impression was taken to make study casts at three time points: before insertion of the first archwire (T0), after 1 month of treatment commencement (T1), and at the end of the leveling and alignment stage (T2), represented by final archwire insertion. LII was used to measure the change in tooth alignment on the casts. It involved measuring the horizontal linear distance among adjacent contact points of the six anterior teeth. The sum of these five measurements gave the value of the index. LII was measured using a digital caliper to the nearest 0.01 mm by the corresponding author. OLAT was calculated by the number of days between T0 and T2.

Time frame: 6 months

Secondary Outcomes

Second Outcome Measure was leveling and alignment improvement percentage (LAIP) of the Mandible teeth throughout the leveling and alignment stage.

OLAT was calculated by the number of days between T0 and T2. LAIP was calculated by dividing the amount of change in the LII value at a specific time point (T1, T2 ; calculated by subtracting the LII value at T1, T2 from the LII value at T0) by Lll value at T0. OLAT was calculated by the number of days between T0 and T2. LAIP was calculated by dividing the amount of change in the LII value at a specific time point (T1, T2 ; calculated by subtracting the LII value at T1, T2 from the LII value at T0) by Lll value at T0.
