To evaluate and compare the effect of a soft drink and a fresh fruit juice on microleakage as well as surface texture of flowable composite (Filtek” Flow 3M Dental products) and resin-modified glass ionomer cement (GIC) (Vitremer” 3M Dental products).

Materials and methods

Seventy noncarious human premolars extracted for orthodontic treatment purpose were collected and stored in saline for microleakage study. The experimental groups comprised of 60 teeth, while the remaining 10 formed the control group. Class V cavities were prepared and restored with RMGIC on the buccal surface and Filtek Flow on the lingual surface for evaluating microleakage. The experimental samples were then divided into two groups (group I: Cola drink and group II: Fresh orange fruit juice) of 30 teeth. Each of this group was further divided into three subgroups (low, medium and high immersion) containing 10 teeth. The control group (group III: Water) contained 10 teeth.

Using a brass mold, 56 pellets were prepared with Filtek” Flow and Vitremer” tri-cure restorative material each for studying surface texture. Again these were divided into experimental group of 48 pellets each and control group of eight pellets each. The experimental samples were then divided into two groups (group I: Cola drink and group II: Fresh orange fruit juice) of 24 pellets of each. Each of this group was further divided into three subgroups (low, medium and high immersion) containing eight pellets each. The control group (group III: Water) contained 16 pellet (eight pellets of each material).

Both the teeth and pellets were subjected to a common immersion regime according to Maupome et al. Microleakage was evaluated by using Rhodamine B dye and surface texture was evaluated prior to immersion and final surface roughness (Ra) after subjecting the pellets to immersion regime.

Statistical analyses used were Chi-square test/Fisher exact test, Wilcoxon's signed rank test and Mann-Whitney test and ANOVA test.

Results and conclusion

The teeth and the pellets showed statistically significant microleakage and surface roughness respectively as the immersion regime increased. Thus, the study conclusively proves that the 'sipping habit’ associated with commonly available low pH beverages, are detrimental to the longevity of restorations.
