Original publication title: Effect of titanium, glass, and polyethylene fibers in reinforcing pericervical dentin with wallpapering technique - An <i>in vitro</i> study.
Plain-English summary
This study looked at a new way to strengthen the area around the roots of teeth that have had root canal treatment, which can help prevent fractures. Researchers tested three types of fibers—titanium, glass, and polyethylene—using a method called wallpapering to see how well they could reinforce this area. They found that teeth treated with these fibers were less likely to break compared to those treated with a standard method. Among the fiber types, titanium provided the best protection against fractures. Overall, using these fibers appears to improve the strength and durability of treated teeth.
Abstract
<h4>Background</h4>To reduce the incidence of vertical root fractures in endodontically treated teeth, this study presents a novel wallpapering technique to reinforce pericervical dentin (PCD) with different types of fibers.<h4>Aim</h4>The objective of the study was to evaluate the effect of the wallpapering technique using titanium, glass, and polyethylene fibers in reinforcing the PCD of endodontically treated teeth.<h4>Materials and methods</h4>Sixty extracted human maxillary molars were resected 4 mm coronal to the cementoenamel junction (CEJ). Root canal treatment was performed and obturated 4 mm below the CEJ. The samples were divided into four groups (n = 15) and restored as follows:• Group 1: Short fiber-reinforced composite (SFRC)• Groups 2, 3, and 4: Wallpapering with titanium mesh, glass fibers, and polyethylene fibers, respectively, followed by SFRC.Fracture resistance was tested using a universal testing machine.<h4>Statistical analysis</h4>One-way ANOVA and post hoc Tukey's test.<h4>Results</h4>The wallpapering groups (Groups 2, 3, and 4) exhibited higher fracture resistance compared to SFRC alone. Among the wallpapering groups, titanium mesh showed the highest fracture resistance, followed by Ribbond and glass fibers.<h4>Conclusion</h4>Wallpapering with fibers reinforces the PCD of endodontically treated teeth, enhancing load-bearing capacity and thereby protecting against vertical root fractures and improving the long-term success of endodontically treated teeth.
