The successful treatment of early childhood dental trauma is influenced by the child’s age, the child’s cooperation, and the time-lapse between the trauma and seeking dental care. Delayed emergency care raises the risk of complications, making vital tooth survival and/or a favourable prognosis less predictable. As a result, prompt treatment and follow-up are critical to reducing the risk of both short and long-term negative outcomes. This case report describes an early childhood trauma to the upper central incisor which was left untreated. It subsequently developed discoloration, pulpal necrosis, thin dentinal walls, and a wide-open apex. An absorbable collagen barrier was placed against which MTA was condensed and filled up to the cementoenamel junction. A subsequent assessment revealed clinical and radiographic success.

Abstract Biomaterials engineered to interact with biological system for either  therapeutic (treat, augment, repair or replace a tissue function of the body) or a diagnostic purpose have underwent biological evolution over a period of time. This can be attributed to advent of new innovative technology combined with human curiosity for search of new materials that mimic biological tissues in terms of physical and chemical properties for orchestration of wound healing and tissue regeneration. The present review focus on the advancements biomaterials have undergone so far and new era of biomimetic dentistry.

Abstract Aim: To compare and evaluate the effect of glide path creation with Nitiflex hand K- file, Proglider and Path file on canal transportation and concentricity in apically curved canals. Objectives: To compare the degree of canal transportation and concentricity between: 1) Glide path preparation with Nitiflex hand-K file vs Proglider file followed by combination of Hyflex EDM and CM file instrumentation 2) Glide path preparation with Proglider file vs Path file followed by combination of Hyflex EDM and CM file instrumentation 3) Glide path preparation with Nitiflex hand- K file vs Path file followed by combination of Hyflex EDM and CM file instrumentation Materials and methods: Forty ISO 20, 0.02 taper, Endo Training Blocks (Dentsply Maillefer) were acquired and divided into following four groups (n = 10): group A, Control group without glide path preparation; group B, Glide path preparation with Nitiflex hand-K file; Group C: Glide path preparation with Proglider file; Group D: Glide path preparation with Path files. In all the groups, combination of Hyflex EDM and CM file instrumentation was done after glide path creation. Pre- and post-instrumentation digital images were processed with Image J Version 1.8.0 software to identify the center of the canal, and then superimposed using Adobe Photoshop 7.0 software. Unpaired/independent t test and One Way ANOVA were used for intergroup comparison of difference of mean scores. Results: In comparison to other groups, training blocks instrumented with Proglider files and a combination of Hyflex EDM and CM files had reduced deviation in canal axis. Conclusion: Following the combination of Hyflex EDM and CM file instrumentation with an earlier glide path created with Proglider file, canal concentricity and canal geometry are better preserved. Key words: Glide path, canal transportation, proglider, path files, Hyflex EDM
