Brief Summary

Orthodontic treatment is an elective procedure to improve the patient's dentofacial appearance. The complex design of fixed appliances provides a platform that leads to increased plaque accumulation around orthodontic brackets. So, the risk to develop demineralization area adjacent to orthodontic brackets is a major barrier in achieving this goal. Oral hygiene is greatly complicated following the placement of fixed orthodontic Appliances. Molar tube in place are considered for nearly all patients experiencing fixed orthodontic therapy over the whole treatment period, which normally lasts 1.5 to 2 years. To the best of the authors' knowledge, the application and antimicrobial efficacy of zinc oxide (ZnO) nanoparticles coating on orthodontic molar tube material has not been integrated clinically. White spot lesions during orthodontic treatment have a documented etiology. Briefly, the accumulation of plaque and food around brackets, bands, wires, and other attachments caused decreased pH and increased S. mutans colonization, which led to the possibility of clinical demineralization.

The aims of study are to assess the antimicrobial effect of nanoparticle coated stainless steel orthodontic molar tube material (OMT) with zinc oxide (ZnO) nanoparticles in relative to uncoated orthodontic molar tube (UOMT) against the streptococcus. mutans\& lactobacllius bacteria that cause white spot lesion around the fixed orthodontic appliance. .

Detailed Description

Aim:

The aim of this prospective randomized clinical trial is to assess the antimicrobial efficacy of nanoparticle coating stainless steel orthodontic molar tube (OMT) with zinc oxide (ZnO) nanoparticles in relative to uncoated orthodontic molar tube (UOMT).

Objectives:

1. Compare the antimicrobial properties of the zno nanoparticle coated OMT in relative to uncoated orthodontic molar tube (UOMT).

2. Evaluate and compare the clinical bond failure rate between the coated OMT and the UOMT. The null hypothesis is that there is no significant difference in the antimicrobial effects and the rate of bond failure between the non-coated and coated stainless steel orthodontic molar tube using ZnO NPs.

Arm && Interventions

Group	Intervention	Description
orthodontic molar tubes (control)	orthodontic molar tubes (control)	The nine orthodontic patients will receive 36 the non-coated orthodontic molar tube in split-mouth cross quadrant manner, In each patient, two diagonal quadrants (i.e., upper right and lower left, or vice versa) will randomly assigned to each coated OMT and UOMT groups. evaluation will be after 2 weeks for microbial assessment biofilm in addition to plaque \& gingival index. patients will be follow up for 3 month to evaluation bond failure rate.
Zinc oxide nanoparticle coated orthodontic molar tubes (experimental)	Zinc oxide nanoparticle coated orthodontic molar tubes (experimental)	The nine orthodontic patients will receive 36 orthodontic molar tubes coated with ZnO nanoparticle in split-mouth cross quadrant manner, In each patient, two diagonal quadrants (i.e., upper right and lower left, or vice versa) will randomly assigned to each coated OMT and UOMT groups. evaluation will be after 2 weeks for microbial assessment biofilm in addition to plaque \& gingival index. patients will be follow up for 3 month to evaluation bond failure rate.

Primary Outcome Measures

Name	Time	Method
Evaluation of the antimicrobial Effect of ZnO Nanoparticles Coated orthodontic molar tube in relative to the uncoated orthodontic molar tube	After 2 weeks	Compare the antimicrobial properties of the zno nanoparticle coated OMT in relative to uncoated orthodontic molar tube (UOMT), through taking swaps from patient and sent to laboratory to culturing swaps samples to evaluating the colony forming unit number of S. mutans\&lactobacillus bacteria which consider mean cause of white spot lesion and compare with the uncoated orthodontic molar tube swaps cultures.

Secondary Outcome Measures

Name	Time	Method
Evaluate and compare the clinical bond failure rate between the coated orthodontic molar tube and the uncoated orthodontic molar tube	3 months	By following up patients for 3 months recording the bond failure occurs through out the this period with date and location of debond tubes for coated and uncoated orthodontic molar tubes.
