Association of Orthodontic Tooth Movement with Leptin Concentration in Gingival Crevicular Fluid.

Objectives: This study aims to evaluate the association of orthodontic tooth movement with the concentration of leptin in gingival crevicular fluid (GCF). Materials and Methods: In thirty orthodontic patients, the concentration of leptin was assessed at baseline, 1 h, 24 h, 7 days, and 1 month after application of orthodontic force. Distalized tooth movement was evaluated by measuring the difference on dental casts at baseline and 1 month after force application. Results: Average concentration of leptin in GCF raises from baseline (T0) to 1 h after application of force (T1). There was a significant association of the overall average concentration of leptin with the degree of tooth movement (correlation coefficient = 0.625). Conclusion: There was a biphasic change in GCF leptin concentration and significant association between rates of tooth movement with GCF leptin concentration.

Role of Text Message Reminder on Oral Hygiene Maintenance of Orthodontic Patients.

INTRODUCTION: Fixed orthodontic treatment is frequently associated with increased plaque accumulation leading to gingivitis and white spot lesions (WSLs). AIM: This study evaluated the role of text message reminder on oral hygiene of orthodontic patients. MATERIALS AND METHODS: A total of 60 patients under fixed orthodontic treatment were randomly divided into two equal groups as control group and study (text message) group. Text message group received reminders about oral hygiene, while the control group did not receive any messages. Oral hygiene of both the groups was evaluated at baseline, 2, and 3 months using plaque indices (PIs) along with WSL status. Data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) statistical software, version 19, with chi-square test and t-test. RESULTS: At the baseline, plaque score was higher in the study group over control group (p > 0.038), whereas it was decreased after 3 months in the test group (p > 0.001). For WSL, there was no significant difference at baseline, but it was significantly lower in study group (p > 0.003). CONCLUSION: Oral hygiene status improved with text message reminder.

Comparative Evaluation of Remineralizing Effect of Novamin and Tricalcium Phosphate on Artificial Caries: An in vitro Study.

AIM: The aim of the present study was to compare the remineralizing efficacy of novamin and tricalcium phosphate (TCP). MATERIALS AND METHODS: Nail varnish was coated to a total of 30 sound human premolars except for 5 mm × 5 mm window. Baseline microhardness was measured for all test samples. Artificial carious lesions were created for all teeth by subjecting them to demineralization process. Then microhardness of demineralized lesion was measured. Later artificial caries teeth were equally divided into two groups to treat with remineralization solution for 10 days; group I: novamin and group II: TCP. After 10 days of pH cycling, microhardness was measured. The data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) statistical software from Chicago SPSS Inc., version 21 and using analysis of variance (ANOVA) post hoc multiple comparisons test for intergroup and significant difference at p < 0.05. RESULTS: In the present study, group I indicated a higher value for remineralization compared with group II (p < 0.05). CONCLUSION: The present study showed that both novamin and TCP were effective in remineralizing the carious lesions. CLINICAL SIGNIFICANCE: This study evaluates the remineralizing potential of novamin and TCP on initial carious lesions.
