“…The studies showed that as the amount of dentine removal increases, the fracture resistance of ETT decreases. (25) Majority of practitioners in the present survey held the same belief that post diameter should not exceed 1/3 rd of the root diameter. The research confirmed that increase in the post diameter creates internal stresses within the root and does not contribute to the retention of the post.…”

Abstract:Objectives: The aim of this study was to determine the knowledge, current approaches, techniques and practices for the restoration of endodontically treated teeth (ETT) among general dental practitioners and specialists in north of Saudi Arabia. Methodology:A standard questionnaire based survey containing 16 multiple choice questions about techniques and treatment methods, frequency of post, type of post, choice of luting cement, core material, reason of failure of endodontic treatment was distributed by hand and through email among 255 general dentists and specialists. The data were processed by using SPSS statistical software. Results:The majority of clinicians (54%) believed that post reinforces the remaining tooth structure and reduces fracture probability. The ferrule effect was considered an important factor in increasing fracture resistance of the ETT (72%). The preferred technique for restoring ETT was core material along with 1-2 mm of ferule (41%) followed by prefabricated post and core build up (25%). On the basis of post material, the most common was metal (43%) followed by fiber post (41%). 2/3 rd length of the root canal for the post length (67%) , 4-5mm apical seal of gutta percha after post placement (47%) and for the post diameter, 1/3 rd of root diameter (51%) was agreed by most of the participants. Composite resin (61%) was the most popular material for core foundation followed by amalgam (23%). Conclusion:The surveyed practitioners had a sound knowledge of the techniques and materials for restoring ETT with the exception that post reinforces the remaining tooth structure and reduces fracture probability.

“…Such conditions are challenging, not only in root canal debridement and filling, but also for the thin dentinal walls increasing the risk of subsequent fracture (Deutsch et al . , Cvek ).…”

“…Previous studies have demonstrated that the main determining factors for the occurrence of root fractures are: the design of the spreaders [22], combined with the stress generated during compaction [18,23], canal width, canal taper, size and other characteristics of the tooth itself [23,24]. Moreover, pre-existing cracks, craze lines or incomplete fractures, especially those in direct contact with the root canal, may propagate and develop into fractures after the endodontic treatment [15].…”

Objective:This study evaluated the effects of root canal obturation employing lateral compaction technique and spreader load of 1.5 kg on the incidence of complete (CVRF) or incomplete vertical root fractures (IVRF). Material and Methods: Twenty-seven distal roots of extracted human mandibular molars were used. All root canals were prepared by biomechanical step-back technique and obturated by lateral compaction technique. The prepared roots were distributed into two groups: G1- experimental (n=17) and G2- control (n=10). During obturation, load of 1.5 kg was applied to a size 30 finger spreader. Pre- and post-obturation images of the coronal portion of the roots were captured by inverted digital microscopy and analyzed by one trained examiner. Data were evaluated by Fisher’s test (p < 0.05) using GrapH Pad Prism 5.0. Results: No roots exhibited CVRF. All fractures observed before and after obturation were IVRF or “other defects”. In G2 (control group), there was no increase of IVRF number. Interestingly, G1 presented an increase in the IVRF number to 70,59% in the 12 teeth out of 17 teeth studied. The statistical analysis showed that the mean of IVRF increased significantly in G1 when compared to G2 (p < 0.05). Conclusions: The application of a 1.5 kg spreader load during lateral compaction technique does not produce complete vertical root fractures, but may produce incomplete fractures or “other defects”.
