NCT05651503
Brackets, bands, ligatures and wires in patients receiving orthodontic treatment with fixed appliances are areas that trap food and impede oral hygiene. An ecological environment facilitating the growth of microorganisms (Actinobacillus, Bacteroides, Prevotella etc.) emerges in the mouth and may cause caries, enamel white spots, gingival inflammation and halitosis. Despite the use of specialized orthodontic brushes, interdental brushes, mouthwashes and topical fluorides, plaque removal remains inadequate in patients with fixed orthodontic appliances. On the other hand, patients undergoing orthodontic treatment with aligners have been found to have better oral hygiene because of less plaque accumulation in their mouth. Probiotics are defined as non-pathogenic bacteria that can benefit the host's general health when taken in sufficient amounts through nutrition. Nowadays probiotics can be used to enhance oral health as they are found to reduce dental biofilm formation, prevent and decrease halitosis in children, adolescents and adults. To date, there are few randomized controlled trials (RCTs) examining the efficacy of oral probiotics in patients with fixed orthodontic appliances and none reporting the incidence of halitosis and the effect of probiotics in orthodontic patients wearing aligners.

Patients at the Orthodontic Department of the University of Damascus Dental School will be examined, and subjects who meet the inclusion criteria will be included. Then after finishing the orthodontic treatment, Patients were randomly assigned into two groups: Open mouth group: The debonding procedure was conducted using the open-mouth technique. All brackets were removed using a Weingart plier (American Orthodontics, Sheboygan, Wisc) by squeezing them from both sides of the mesial-distal surfaces. Before debonding, the stainless steel finishing archwires (0.017 × 0.025 inches) were removed. Biting-on a-cotton-roll-group: All brackets were removed using the same plier. The brackets were debonded using a Weingart plier (American Orthodontics, Sheboygan, Wisc) by squeezing them from both sides of the mesial-distal surfaces. Additionally, cotton rolls were placed between the upper and lower teeth, and patients were instructed to bite on them during the procedure. Before debonding, the stainless steel finishing archwires (0.017 × 0.025 inches) were removed. Patients in the second group were instructed to bite on a cotton roll throughout the debonding process.

Currently, orthodontic treatment takes 2-3 years.. If we accelerate tooth movement by low energy laser therapy, we could reduce treatment time. Low Level Laser Therapy(LLLT) applied in Orthodontic Tooth Movement, which stimulates formation of osteoclast-like cells expression in vitro. Osteoclast can be served as an index for tooth movement. Increasing the number of osteoclast will increase bone formation and tooth movement. We plan to find a useful clinical protocol to improve the efficiency of orthodontic tooth movement. Test low energy laser in vitro. Find an effective wavelength and irradiation time to stimulate formation of osteoclast. Develop an useful protocol that clinical orthodontist could follow and reduce orthodontic treatment time.

The aim of this study is to compare the clinical efficacy of different residual orthodontic adhesive removing methods for rebonding debonded metal attachments.
NCT06403033
Correcting the skeletal class II using functional appliances, whether removable or fixed, always leads to skeletal and alveolar effects. However, some of these effects are unfavorable, the most significant being the loss of support in the lower dental arch. This loss of support leads to an uncontrolled labial inclination of the lower incisors and mesial movement of the lower; these dentoalveolar effects impact the degree of skeletal correction that can be achieved. Therefore, this study aimed to evaluate the skeletal and dentoalveolar effects following the use of a mini-implant-supported Twin-Block appliance compared to the conventional Twin-Block.

NCT05812456
some orthodontic brands are more expensive than others, one of the primary outcomes of this study is to know if is it worth using expensive brands? will it provide better quality treatment, in particular, bond strength? The treatment duration is long therefore it is expensive, either for the orthodontist and/or the patient. This study will be comparing the bond strength of different commercial brands of stainless steel brackets.

NCT05644119
The goal of this split-mouth, head-to-head, randomized controlled trial is to compare the effects of a fixed straight retainer with the V- loop bonded retainer on periodontal health in patients with the requirement of continuous fixed retention for 12-24 months after orthodontic treatment. The main question it aims to answer is whether the V- loop bonded retainer is more effective than fixed straight retainer for periodontal health management. Each patient will receive 2 lower fixed and bonded retainers: (1) a straight wire retainer (SWR) and (2) a looped wire retainer (LWR). Patients will be asked to floss once daily with a thread flosser. Researchers will compare the effects of two types of retainers to see if there is a statistically significant difference.
NCT05549089
CAD/CAM systems have assisted orthodontists in planning and positioning brackets to minimize errors and improve the excellence of treatment. This study aimed to validate measurements obtained from manual and digital systems, as well as evaluate the effectiveness, and periodontal changes that occurred after the treatment. Materials and Methods: This study is a prospective randomized controlled trial, in which clinical evaluation of virtual setup (digital and manual) techniques versus CAD/CAM brackets (Ormco© Insignia™ .022" twin brackets) in terms of expression of bracket prescription and treatment outcome. The sample consisted of 30 young adults with Angle Class I malocclusion. Cone beam computer tomography (CBCT) were obtained before and after the treatment to assess the parallelism between the dental roots and periodontal conditions. Digital impression by three dimensional (3D) intraoral scans (IOS) will be obtained for all participants. The 3D models are converted to stereolithography (STL) for all groups. The sample will be dividing randomly into three groups; the first one treated with CAD/CAM brackets (Ormco© Insignia™ .022" twin brackets), while the other two groups were treated by customization of bracket base of the conventional pre-adjusted twin bracket with orthodontic adhesive material, this will be done through planning and creating the virtual setup by using Maestro® 3D Ortho Studio software. The Indirect bonding devices for the second group will manufacturing from 3D printed models while third group from the manual double-layer vacuum-formed thermoplastic trays. All patients will treat with fixed orthodontic twin brackets appliances. The 3D models of the Virtual setup are comparing with the treated occlusion. The linear and angular measurements are performing by the Geomagic® software and using the 3Shape's Ortho-Analyzer TM software in all groups to assess the American Board of Orthodontics grading system scores. Random errors are assessing by Intra-class Correlation Coefficient (ICC) and method errors. Descriptive statistical analysis, Shapiro-Wilk test to detect the normality of variable distribution and the Chi-square test evaluated whether the ABO scores measurements are within the limits of agreement of each criterion. ABO scores between both groups are analyze by using Wilcoxon test. The Bland-Altman analysis evaluated if differences are within the limits of agreement.
NCT04598633
Orthodontic treatment with fixed appliances can be necessary to correct malocclusions in adolescence or adulthood. It its known that orthodontic treatment induces aseptic pseudo-inflammatory reactions. However, studies could show that an increase of certain inflammatory cytokines during orthodontic treatment correlated with a higher risk of root resorption. Moreover, it has been shown that orthodontic treatment leads to a dysbiosis of the oral microbiome especially during the first 3 months of the orthodontic treatment. This could be a potential risk factor as the inflammation of periodontitis during an orthodontic treatment could favor root resorption and progressive destruction of the periodontal apparatus. Probiotics are already used successfully as an adjuvant therapy in the treatment of periodontitis to improve clinical parameters and to reduce local inflammation. However, there are only a few studies that investigated the influence of probiotics during an orthodontic treatment. Therefore, the aim of the study is to investigate if the daily intake of lozenges containing probiotics versus placebo lozenges during the first 3 months of orthodontic treatment with fixed appliances can improve clinical parameters, reduce local inflammation and prevent a dysbiosis of the oral microbiome.

NCT04604262
There is no long term evidence to show that the use of Waterpik® is effective for orthodontic patients with fixed braces. A Cochrane Systematic Review confirms this. The aims of this study is to find out if the use of Waterpik® in addition to the manual toothbrush is better to maintain clean teeth in patients with fixed braces. The null hypothesis is that there is no difference between patients using either Waterpik® in addition to the manual toothbrush (treatment group) when compared with patients using just the manual toothbrush (control group).
