| description | Introduction: The influence of the remaining coronal tooth
structure along with intra-radicular esthetic posts increases
fracture resistance of fractured teeth especially in the anterior
region. The advent of resin based luting cements improves the
adhesion of fiber posts.
Aim: To evaluate the fracture resistance of endodontically
treated roots restored with fiber posts using different resin
cements – Calibra (etch and rinse), PermaFlo® DC (self-etch
primer) and SmartCem2 (self-adhesive).
Materials and Methods: Extracted human maxillary central
incisors having similar dimensions were decoronated at
the Cemento-Enamel Junction (CEJ) to create 16mm long
specimens and endodontically treated. A total of 45 teeth were
divided into three groups with 15 teeth each for cementation
of easy fiber posts (size1, 0.8mm diameter). Post spaces were
prepared to a depth of 10mm. Group 1 – Caulk 34% phosphoric
acid gel, dual cure adhesive Prime and Bond NT followed by
luting of post with Calibra cement. Group 2 – Ultra – etch then
Primer A and Primer B, and PermaFlo® DC was used to cement
the post. Group 3 – SmartCem2 [1:1 ratio] was used to cement
the post. The excess lengths of posts were seared and teeth
were mounted on acrylic blocks and loaded under compressive
force to the long axis of the tooth which increased in periodic
pattern of 1mm/min. The value of the force at which each root
section gets fractured was noted. The data were statistically
analysed using ANOVA and Tukey’s Test.
Results: The mean fracture load (and SD) were as follows Group
1 – 762.400 (251.490); Group 2 – 662.933 (206.709); Group 3 –
657.800 (57.372). No statistically significant differences were
seen among all three Groups, p-value (0.228).
Conclusion: Posts cemented using self -adhesive resin cement
SmartCem2 have highest fracture resistance and bonding
efficacy of self-adhesive technique showed reliably better results
but was comparable to total–etch and self–etch techniques. |
