Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Studies examining the effectiveness of toothpastes on white spot lesions seen with fluorescence color change during orthodontic treatment are available in the literature in vitro and in vivo. Since in vivo studies are still insufficient in number, some records showing oral hygiene and periodontal health were added to the records to be taken from patients in this study. Literature studies have taken similar records, such as an in-vivo study by Hoffman et al., which evaluated the effects of two different toothpastes on white spot lesions and included plaque index and gingival index records taken from patients in 3-month periods. Another study by Kirschneck et al. investigated the effectiveness of fluoride pastes and varnishes on white spot lesions and recorded ICDAS index and gingival index values from patients at 4, 12, and 20 weeks after the beginning of treatment. Karabekiroğlu et al. compared a group using only fluoride toothpaste with a test group in which 10% casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste was applied topically, including records such as ICDAS 2, DMFT and DMFS index, and QLF records. In the study to be conducted, comprehensive records such as DMFT index, gingival index, plaque index, ICDAS 2 index, QLF records, and color analysis of the teeth obtained from digital models taken with the intraoral scanning device will be collected from patients at specified periods. Since the tooth color tones determined with the 3Shape Trios device, the intraoral scanning device used in the clinic, are based on the Vita scale, a reference article in the literature will be used to facilitate statistical analysis. The images of the scanning records will be transferred to Adobe Photoshop, and the color values will be converted to L.a.b. and ∆E parameters. This conversion allows for the numerical equivalent of the color tones, making statistical analysis easier. The demineralization values of 10 teeth, excluding the molars in the upper jaw, will be measured using the QLF device's own software.
Methods
The study will include routinely taken three-dimensional models, fluorescence photographs, gingival index, periodontal index, ICDAS II, and DMFT index records of patients who have received orthodontic treatment at Erciyes University Faculty of Dentistry and who have been using the same toothpaste for a long time.
Three different toothpaste groups to be included in the study were determined. These toothpastes will be examined in three groups as those routinely used by patients with fluoride effect, those containing lactoperoxidase, and those without fluoride. The number of patients in the groups was determined using the G\*Power (Ver. 3.1.9.7, Heinrich Heine University, Dusseldorf, Germany) power analysis program, based on DF values of the control group followed up with standard toothpaste in a study by Bröchner et al. in 2011. According to the two-way student t-test power analysis with d=1.384 effect value, 95% power, and alpha=0.05 parameters, at least 12 individuals should be in each group. To account for possible exclusions from the clinical study, 15 individuals were included in each group. As a result, a total of 45 patients, with 15 patients in each group, will be included in the study. The patients will be randomly assigned to three groups using a free randomization program mentioned in the literature. The purpose of this method is to ensure that the distribution of the patients into groups is random. Traditionally, dental models, intraoral and extraoral photographs, radiographic images, and clinical measurement records will be taken from patients before orthodontic treatment. Digital models obtained by scanning the upper and lower jaws using an intraoral scanner (3shape TRIOS) will be used. The purpose of this is to evaluate whether there will be a change in tooth color during the orthodontic treatment process by comparing them with records taken in the later stages of treatment. Photographic records will also be taken with a Quantitative Laser-Induced Fluorescence (QLF) device, which will be used to examine fluorescence color changes on the tooth surfaces. Patients who have started their treatment after the records are taken will be divided into three groups, and each group will use the assigned toothpaste throughout the treatment. The group using only fluoride-containing toothpaste will serve as the control group. The study will evaluate upper incisors, canines, first, and second premolars. Periodontal and gingival index measurements will be taken as part of the routine examination before, during, and at the end of orthodontic treatment. ICDAS II and DMFT tooth decay presence scoring methods will be performed through intraoral examination during photo record collection.
Statistical Evaluation
Statistical evaluations will be performed with the R-based JAMOVI analysis program. Statistical comparisons of changes in the number of white spot lesions on teeth evaluated over time will be made using analysis of variance (ANOVA) for repeated measurements within each group. Suppose a statistically significant difference is observed between measurement times within each group. In that case, paired samples t-tests will be used to determine at which time points the difference is statistically significant. Whether a statistically significant difference exists between groups, between times, and in the group-time interaction will be evaluated separately using multiple analyses of variance (ANOVA). If a statistically significant difference is observed between groups or time points, Tukey HSD multiple comparison tests will be used to identify the specific differences. The statistical significance value will be set at p\<0.05.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group 1 Control
Individuals using a toothpaste (Colgate) with a fluoride content of 1450 ppm, which is frequently reported in the literature and used commercially internationally, will be included. Whether the patients continue to use the relevant toothpaste will be confirmed with information provided by the patient at each session of orthodontic treatment.

Fixed orthodontic treatment
For standard fixed orthodontic treatment, orthodontic brackets and mechanics will be applied.
Group 2 Lactoperoxidase
Individuals using a toothpaste (Curaprox) with lactoperoxidase and content of 1450 ppm fluoride, which is frequently reported in the literature and used commercially internationally, will be included. Whether the patients continue to use the relevant toothpaste will be confirmed with information provided by the patient at each session of orthodontic treatment.
