Evaluation to prevent the Physical Changes in Colored Elastomeric Modules when exposed to various Dietary Media

AIM AND OBJECTIVE

The aim of the study is to analyze and compare the variation of lumen size and thickness of the elastomeric colored modules when immersed in four selected dietary media.

MATERIALS AND METHODS

Sample size of 40 modules on each color - such as red, blue, green, and black - was taken and immersed in four dietary media (artificial saliva, coke mixed with artificial saliva, turmeric mixed with artificial saliva, and coffee mixed with artificial saliva). Beakers containing different dietary media and color modules are kept in the incubator at 37°C for 72 hours. After incubation period, all the segments of module strips removed from the dietary media were placed under the electric lamp and photographs were taken using Canon camera (SX400 IS). Photographs were transferred to GIMP software, and lumen size and thickness variation in the modules was measured.

RESULTS

Statistical analysis were performed using analysis of variance and t-test in Statistical Package for the Social Sciences software. It showed significant difference in thickness of black module in all dietary media. Significant difference existed between all the lumen sizes of four color modules in four dietary media.

CONCLUSION

This study was done to identify the material that has more changes in physical properties when exposed to various dietary media.

CLINICAL SIGNIFICANCE

According to the results obtained, black color modules have increased in lumen size in all dietary media. In thickness, red color module showed less variation and black color module exhibited more variation.

Early prevention and intervention of Class II division 1 in growing patients

Early screening and diagnosis help in preventing and intercepting the severity of the malocclusion which helps in addressing the esthetic and functional concerns. Growth modulation such as mandibular advancement has been an effective procedure in orthodontics. Mandibular growth advancer (MGA) and PowerScope are gaining popularity recently as these are effective in achieving the mandibular advancement and ease of fabrication, placement, and wear. MGA was fabricated by making the upper and lower splints separately and are placed in the oral cavity by joining the two splints in the new construction bite using cold cure, MGA when worn during growth phase helps in condylar remodeling in the temporomandibular joint thus helps in advancement of the mandible. The proclination of the upper anteriors in Class II division 1 can be moved lingually by activating the labial bow in the splint. Dr. Andy Hayes worked in conjunction with American orthodontics developed PowerScope. PowerScope delivers Class II correction with a combination of patient comfort and ease of use that was unmatched among other appliances. This ready to use chairside solution required no laboratory setup, making for a much quicker, and easier installation process and appointment. PowerScopes high quality, fixed one-piece design requires no patient compliance. These superior qualities of PowerScope help in correction of Class II skeletal growing patient in conjunction with fixed orthodontic therapy. MGA and PowerScope were chosen as a functional appliance for this study, which shows decreased ANB angle and effective mandible length was increased.
