Abstract Objective: To evaluate the effect of external bleaching on the color and luminosity of inactive white-spot lesions (WSLs) present after fixed orthodontic appliance treatment as means for achieving color matching of the WSLs with adjacent tooth surfaces. Materials and Methods: Ten patients with inactive WSLs after therapy with fixed orthodontic appliances were selected. At baseline, the lightness of maxillary incisors and canines was assessed with a colorimeter. Color determinations were performed in the area of the initial lesions (F1) and at adjacent, sound enamel areas (F2). Then, anterior teeth were bleached once with a bleaching gel for 60 minutes. After a break of 14 days, in-office bleaching was followed by a 2-week home bleaching period with daily home bleaching for 1 hour. After this, color determinations were repeated. Additionally, patients were asked to fill out a questionnaire to provide information about their degree of contentment with the treatment. Results: The lightness values of both the F1 and F2 regions were significantly higher after bleaching as compared with baseline. F2 L-values increased significantly more as compared with F1, indicating a better color matching of these two areas in comparison with baseline. All patients were satisfied with the outcome of the bleaching therapy. Conclusion: External bleaching is able to satisfactorily camouflage WSLs visible after therapy with fixed orthodontic appliances.

Background: White spot lesions (enamel demineralization) is one of the most common and a significant risk associated with orthodontic treatment. Objective: To determine the prevalence of white spot lesion during fixed orthodontic treatment. Method: This prospective observational study and was conducted in the Department of Orthodontics and Dentofacial Orthopedics from January 2016 to December 2017 over a period of two years. Patients with fixed orthodontic appliance age between 12-30 years of both sex attended for follow up were included in this study. After taking written consent, a questionnaire included socio-demographic data, clinical and outcome variables including routine clinical photographs to examine WSL were filled up for each patient. Routine clinical photographs to examine WSL were taken after 6 months and 12 months of fixing orthodontics appliance. Qualitative data were expressed as frequency distribution and percentage. Results: Maximum patients were in age group 12 – 16 years and prevalence of WSL was also sought maximum in this group. Out of 36 cases with WSL, 14 (38.9%) were male and 22 (61.1%) were female. Prevalence of WSL after six month of fixing orthodontic appliance was 21.8% and 26.1% after 12 months. Prevalence of WSL after six month of fixing orthodontic appliance in male was 26.4% & in female was 19.6% and after 12 month of fixing orthodontic appliance it was 30.2% in male and 24.1% in female. After six months of fixing orthodontic appliance 1-3 WSLs was found in 17.0% cases and ≥ 4 WSLs in 4.8% cases. After twelve months of fixing orthodontic appliance 1-3 WSLs was found in 19.4% cases and ≥ 4 WSLs in 6.7% cases. Maximum WSL was found in maxillary incisors. Conclusion: This study showed that 21.8% of the study subjects developed white spot lesions during orthodontic procedure and incisors were the most common affected teeth. Update Dent.

Plaque accumulation and white spot lesions are common adverse effects of fixed orthodontic appliance use. This study compared the effects between enzyme-containing and conventional dentifrices on orthodontic patients. This double-blind randomized controlled trial included 42 orthodontic patients (25 women and 17 men: 22.7 ± 4.2 years) from Taipei Medical University Hospital between 2017 and 2018. The patients were randomly divided into three groups and assigned to dentifrice use during the first 3 months of the orthodontic treatment: group 1 used dentifrices containing enzymes including amyloglucosidase and glucose oxidase, group 2 used dentifrices containing 1450 ppm fluoride, and group 3 used natural dentifrices containing no chemical agent. White spot lesion index (WSL), gingival bleeding index (GBI), and visible plaque index (VPI) were recorded and analyzed. WSL, GBI, and VPI values exhibited no significant difference among the three groups. WSL increased significantly in group 3, GBI decreased significantly in all groups, and VPI decreased significantly in groups 1 and 2. No significant difference was observed between the use of enzyme-containing and conventional dentifrices after fixed orthodontic appliance placement.

Objective: To compare two fluorinated varnishes for the control of white spot lesions.Material and Methods: A randomized controlled clinical trial was conducted. A total of 103 active whitespot lesions on permanent upper anterior teeth from 24 patients, aged 7 to 9 years were randomly assigned totwo groups, G1: Duraphat® (n=52) and G2: DuraShield® (n=51). Weekly applications were perform for fourconsecutive weeks. Fifth week the dimension, regression and activity of the lesions were evaluated. Student’sT test, Wilcoxon Ranks and Chi square were used at 5% significance. Results: At the end of the study, the lesion reduction was observed in 69.7%, finding significant differences(p<0.05) in the mean of the initial and final dimensions in general (2.74 mm to 1.91 mm) and in each group, G1(2.84 mm to 2.03 mm), G2 (2.64 mm to 1.78 mm). In the activity of the lesions, it was found in the G1, 12 active and6 inactive lesions; while in G2, there were 14 active and 29 inactive; these differences were significant (p<0.05). Conclusions: The two evaluated products showed similar clinical efficacy in the remineralization of activewhite spot lesions after 4 weeks of therapy.

Abstract Background This study was conducted in order to explore the effects of orthodontic tooth movement (OTM) on the changes of salivary proteome. This prospective observational pilot study recruited 12 healthy teenage boys with malocclusion treated with a fixed orthodontic appliance and 6 appropriate control participants. Saliva samples were collected a day before and at 0, 2, 7, and 30 days after initialization of treatment, corresponding to the initial, lag, and post-lag phases of OTM. Pooled samples were analyzed by liquid chromatography-mass spectrometry, ELISA, and Western blotting. To date, there is no published data on the presence of BMP molecules or their antagonists in the saliva or in the gingival cervical fluid related to orthodontic conditions. Results A total of 198 identified saliva proteins were classified based on their functional characteristics. Proteins involved in bone remodeling were observed exclusively 30 days post appliance placement, including bone morphogenetic protein 4 (BMP4), a BMP antagonist BMP-binding endothelial regulator, insulin-like growth factor-binding protein 3, cytoskeleton-associated protein 4, and fibroblast growth factor 5. Based on the analysis of protein interactions, BMP4 was found to have a central position in this OTM-related protein network. Conclusions The placement of a fixed orthodontic appliance induced occurrence of proteins involved in bone remodeling in the saliva at a time corresponding to the post-lag period of OTM. Limitations of this study include a relatively small sample size, limited time of monitoring patients, and the lack of interindividual variability assessment.
