Aim:To evaluate the influence of immediate and delayed post space preparation on sealing ability of Resilon-Epiphany and Gutta percha-AH plus.Materials and Methods:Eighty extracted permanent maxillary central and lateral incisors were decoronated. Roots canals were prepared and obturated. Samples were divided into four groups depending on the time of post space preparation and obturated material. Group I and II: Immediate and delayed post space preparation respectively with Gutta percha/AH plus as obturating material. Group III and IV: Immediate and delayed post space preparation with Resilon/Epiphany as the obturating material. The samples were kept in methylene blue dye, sectioned and then measured under stereomicroscope and studied under SEM.Statistical Analysis:The data was subjected to statistical analysis using unpaired t-test.Results:There was significant difference found between immediate and delayed post space preparation in Resilon-Epiphany group (P = 0.0109) as well as in AH plus-GP group (<0.0001). Difference in the sealing ability of the two materials was seen in delayed group (P = 0.0202). No statistically significant result was found between the two obturating materials when post space was prepared immediately (P = 0.0875).Conclusion:Within the limitations of this study, there was significantly less leakage when post space is prepared immediately in both the groups. Resilon-Epiphany shows better results when post space is delayed amongst the two whereas in immediate post space preparation there is no significant difference.
This paper highlights the fact that many anterior teeth requiring restoration are severely weakened, having wide flared canal spaces and thin dentinal walls, and are at a high risk of getting fractured. An 20 year old female patient reported with the complaint of unesthetic smile due to fracture and discolored tooth. She gave a history of trauma around 4-5 years back. This case was managed by the customization of fiber reinforced posts which has made a great impact on esthetics and redistribution of stresses along the radicular space and dentin tissue conservation. Thus modern techniques reflect a change from what was once considered prosthodontic procedure to one which marries endodontic principles with sound understanding of mechanical objectives.
