Orthodontic Treatment on Oral Microbiota and Salivary Proteins

Study on the changes in oral microbiota during orthodontic treatment in patients aged 8-18 years. Orthodontic patients treated at Stomatology Hospital of Xi'an Jiaotong University from March 2025 to March 2027 will be recruited. Prior to orthodontic treatment, routine preoperative examinations will be conducted, informed consent forms will be signed, baseline oral conditions will be recorded, and oral and psychological-related questionnaires will be completed. Patients will be informed of the need for regular oral hygiene check-ups, caries risk assessments will be performed, and plaque, saliva, and intraoral photographs will be collected. During orthodontic treatment, plaque samples will be collected every 3 months, and saliva samples will be collected every 6 months until the treatment is completed to evaluate the changes in oral microbiota throughout the orthodontic process.

Remineralization Efficacy of Moringa Oleifera Varnish Vs MI Varnish in Initial Carious Lesions Over 6 Months Follow Up: a Randomized Controlled Clinical Trial

This randomized clinical trial aimed to test the remineralization effect of laboratory prepared Moringa Oleifera based varnish compared to MI varnish (CPP-ACP) on incipient carious lesions. The study could include any of the following participants: age: 25-35 years, males or females, presentation with at least one active WSLs on the study teeth at the start of the study, good oral hygiene, co-operative patients approving to participate in the trial, have sufficient cognitive ability to understand consent procedures. The main question it aims to answer is in patients with initial caries lesions will Moringa Oleifera varnish have same remineralization efficacy as MI Varnish after 6 months follow up? MI varnish will be used as a comparator as it has been shown in many studies to be superior to fluoride varnish with NaF alone in arresting early caries lesions. The active ingredient, CPP-ACP can slowly release, localize and stabilize amorphous calcium, phosphate, and fluoride on the enamel surface which aids in deep mineralization of white spot lesions.

Assessing the Effects of Resin Infiltration and Resin Modified Glass Ionomer on the Color Changes of White Spot Lesions in a Clinical and Laboratory Setting

The goal of this clinical trial is to assess the efficacy of "Icon® resin infiltration" and "VanishTM XT varnish" in restoring the appearance of white spot lesions WSLs in healthy children affected with anterior white spot lesions. The main questions it aims to answer are: 1- Are Icon resin infiltration (RI) and Vanish™ XT varnish comparable in restoring esthetics of white spot lesions? Researchers will compare Resin infiltration to vanish xt varnish to see if they are effective in masking white spot lesions Participants will: * Have their white spot lesions treated in the dental clinic by the intervention methods * Visit the clinic after 1 month, 3 months and 6 months to assess the restorations objectively and subjectively
