The Effect of Vitamin D3 on the Rate of Orthodontic Tooth Movement

Not Applicable

Completed

• Conditions: Tooth Position Anomalies
• Interventions: Procedure: Micro-osteoperforation

• Registration Number: NCT04837781
• Lead Sponsor: University of Baghdad

Brief Summary

The aim of this study is to evaluate the effect of vitamin D3 deficiency on the rate of orthodontic tooth movement in both conventional and accelerated orthodontic. Assessing both lower anterior teeth alignment and the rate of maxillary canine retraction.

Detailed Description

To evaluate the effect of vitamin D deficiency on the rate of orthodontic tooth movement in both conventional and accelerated orthodontic, additionally find the effect of vitamin D deficiency on molar anchorage loss, canine rotation, lower incisor crowding alignment time, pain experienced by the patient during OTM and rate of orthodontically induce apical root resorption.

Arm && Interventions

Group	Intervention	Description
Normal vitamin D	Micro-osteoperforation	Include patients with normal vitamin D level (above 30ng/ml). Vitamin D level will be measured at the beginning of treatment if there is deficiency then the patient refer to specialized physician to be supplied with vitamin D supplement to optimized the level to normal then start orthodontic treatment
Vitamin D deficiency	Micro-osteoperforation	Include patients with unknown vitamin D level until time of canine retraction where we measure level if deficiency exist (below 30ng/ml) then the patient will be referred to specialized physician to be supplied with vitamin D supplement.
Control	Micro-osteoperforation	includes patients with unknown vitamin D level until the completion of canine retraction where we measure level. If deficiency exists (below 30ng/ml) then we will refer the patient to specialized physician to be supplied with vitamin D supplement

Primary Outcome Measures

Name	Time	Method
Canine retraction rate	16 weeks	Maxillary study model will be 3D scan using optical 3D scanner(Smart Optic,Germany) then measurement done on digital model using 3D program( DentalCad,Galway,3.0,2021),to measure distance from tip of canine to 3rd palatal raguea on both side

Secondary Outcome Measures

Name	Time	Method
Root resorption	12 weeks	The amount of root resorption was measured at the start of treatment and after 12 weeks, the length of the root was recoded at these time intervals. Radiographic films were positioned using a customized sensor holder for the lower anterior teeth with a 7cm film-cone distance using long cone paralleling technique. The radiographs were made at 70kV and 8mA DC with an exposure of 0.25 seconds.
Alignment efficiency	12 weeks	3D scanned study models were used to measure the amount of crowding in the mandibular anterior teeth using 3Dprogram (DentalCad,Galway,3.0,2021). If Little's irregularity index is less than 1mm and alignment improvement not above 0.5 mm between two successive visits, then treatment is regarded as finished.
pain perception	7 days	Evaluations of pain/discomfort was made in the evening on a daily basis over the first 7 days after bonding using a 10- point visual analog scale (VAS) of 10cm length. The highest pain level experienced should be reported by each patient.; The recording sheet was received by all the patients on the day of bonding, it included seven visual analog scales (one for each day) and the patients were given oral instructions on how to finish the VAS by marking the point on the line which supposed to represent the maximum pain that they felt per day, with 0 refers to "no pain" and 10 refers to "intolerable pain". Patients were reminded daily by a phone call or a text message to mark the recording sheet and to bring it on their next appointment
