Color depth penetration of direct and indirect composite after one month interaction with different colored drinks

Abstract

Aim: The aim of this study was to evaluate and compare the color depth penetration of direct and indirect composite after one month interaction with three different colored drinks. Materials and method: Seventy sound extracted molars were collected and stored in saline at room temperature. The teeth were divided into two groups (group I –direct restorative technique and group II indirect restorative technique) and Class I cavity were prepared and restored. Specimens were immersed in cold drink, tea, food color (turmeric solution) and control group (distilled water) for one month, three times a day, and one hour each. Teeth were then soaked in Rhodamine B dye for 24 hours and then sectioned mesio-distally and evaluated under stereomicroscope at 10X magnification. The statistical analysis was done by One Way ANOVA with post hoc test. Results: The highest colour penetration was observed in indirect composite restorations with turmeric group and lowest colour penetration in direct composite restorations with tea groupConclusion: Indirect composite restorations showed more color penetration than direct restorations.
