A bstract Background and objectives Fragment reattachment procedure provides conservative treatment option when an intact fractured fragment is available. Rewetting of fractured fragment before reattaching has shown better bond strength of attached fragment. Therefore, fracture resistance of reattached fractured fragment with hydration and without hydration was evaluated and compared. Materials and methods Ellis class II fracture was induced in selected and coded 60 extracted maxillary central incisors using a custom-made-wise and assigned into group I and group II (without hydration and with hydration) and both the groups were further divided into two groups (1 week and 3 months). In group I, fractured fragments were reattached after bench-drying for 24 hours. In group II, fractured fragments were reattached after hydrating for 1 hour following bench-drying for 24 hours. Composite (Filtek Z350 XT, Universal Restorative, 3M ESPE) was used to reattach the fractured fragments. Reattached fractured fragments were stored in artificial saliva for 1 week and 3 months and subjected to fracture resistance test using Universal Testing Machine. The data obtained were tabulated and statistically analyzed. Results Fracture resistance in hydration samples was higher than without hydration at the end of 1 week and 3 months statistically. Fracture resistance of fractured fragment at the end of 3 months was higher in both with hydration and without hydration but was not significant with hydration. Conclusion Hydration of fractured fragment before reattachment procedure has shown better fracture resistance and improved further after storing in artificial saliva for 3 months.

Background: The premature loss of the primary teeth after the eruption of first permanent molar can result in mesial shift of the first permanent molar. In such circumstances, we require space regainer. The "banded helical retractor" was designed to overcome some of the limitations of the conventional removable and fixed regainers. Aim and objectives: This paper presents a case report with premature loss of second deciduous molar after the eruption of first permanent molar, and regaining the space loss by using innovative design "banded helical retractor". Case description: A 7-year-old patient with loss of space due to early exfoliation of 75 was given an innovative space regainer "banded helical retractor". Results: After 6-weeks followup, space was regained with uprighting of molars. Conclusion: "Banded helical retractor" as a space regainer was effective in regaining the space in the short duration of time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
