Controlling Effect of Food Dyes used World Wide on Colour Stability of Orthodontic Composite Bracket- An in vitro study

Abstract

T Aim: The aim of this study was to evaluate the colour stability of esthetic orthodontic composite bracket after immersion in various food dyes and its control measurement. Composite bracket were immersed into four different solutions: coffee, tea, turmeric, coca cola solution. Sample was kept at in 37 degree Celsius. Colour reading were evaluated  after T0, T1 (24 hour), T2 (72 hour), T3 (144 hour) immersion .all examined  orthodontic bracket showed a significant difference in discoloration and for controlling effect of food dyes same orthodontic  composite bracket are brushed using hydrogen peroxide dentifrice for 30 days.

Objective: To asses colour stability of esthetic orthodontic composite bracket after immersion in various food dyes and control measures.

Material and Method: Orthodontic composite bracket were divided into 4 group n= 4, each group contains 4 orthodontic composite bracket and the solution in which they were immersed (coffee, tea, turmeric, coke). Chromatic changes were analyzed with the aid of visual inspection at four specific time intervals. First assessment was as received from manufacturer calibrated as T0. Thereafter 24 hour T1, 72 hour T3, 144 hour T4. Readings were observed. the stained orthodontic bracket was removed from the solution the specimen immersed in food dyes were brushed for and brushed with dentifrice containing hydrogen peroxide 1 min daily with hydrogen, stored in artificial saliva until next day, the cycle was repeated for 30 days after this bracket were brushed for 30 days using hydrogen peroxide containing dentifrice, the colour assessment was done using visual assessment.

Conclusion: Orthodontic composite bracket shows colour variation when exposed to food dyes like turmeric coffee, black tea, coca-cola. Maximum staining reported with turmeric followed by coffee, coca- cola and tea. Hydrogen peroxide containing dentifrice reduces stain within clinically perceptible range.he cosmetic manufacturing industry of India is rapidly expanding, driven by rising consumer demand, formulation innovations, and globalization. However, India’s Cosmetic Industry requires many approvals before it can fully commence. One of which is the approval from the Central Pollution Control Board.  The Central Pollution Control Board engages in an essential regulatory role in mitigating the environmental impacts through frameworks such as Consent to Establish and Consent to Operate. This article meticulously examines the environmental regulations imposed on cosmetic manufacturers, the pollution index score-based classification of industry sectors, and the effluents and emissions treatment measures. It highlights recent regulatory developments, technological interventions for sustainability, and compliance challenges, offering recommendations for a more harmonized and environmentally conscious cosmetic industry in India.
