ABSTRACTAlthough vertical root fracture (VRF) is mostly found in endodontically treated teeth, it also occurs spontaneously. If VRF is recognized after endodontic treatment, it is considered to be iatrogenic and can lead to legal trouble. However, legal problems can be averted if the dentist can prove that the VRF existed before endodontic treatment. This case report describes an unusual, spontaneous VRF in an endodontically treated tooth and presents a useful tip for determining whether a fracture is iatrogenic. We performed nonsurgical endodontic treatment on a mandibular first molar with irreversible pulpitis. After 6 months, the patient revisited with localized swelling, and we diagnosed VRF of the mesial root. We extracted the tooth and prepared it for microscopic examination. We found gutta-percha in the fracture line of the transversely sectioned root, and it appeared to have penetrated to the fracture line through the force generated from the filling. The patient was informed and agreed that the fracture occurred spontaneously before treatment. This case demonstrates the time point of VRF occurrence by identifying the presence of gutta-percha in the fracture line. We suggest that this procedure can be used to demonstrate whether VRFs in endodontically treated teeth are spontaneous or iatrogenic.

Endodontic Retreatment

Background: The failure of endodontic treatment caused by failure of the restoration and bacterial invation. Alongside proper chemical and mechanical preparation and hermetic obturation of the root canal system, another essential factor is ensuring a permanent and hermetically-sealed restoration following endodontic treatment. Endodontic retreatment encompasses the efforts to salvage a failing previously endodontically treated tooth. As a result of advances in endodontic materials and adhesive systems, restorations in the form of fiber post and adhesively cemented crown are becoming a choice in cases of teeth that have extensive damage. Case: A case is presented a 45-year-old female was referred to Prof. Soedomo Dental Hospital with a complaint of pain in mandibular second premolar which was earlier endodontically treated. Clinical and radiographic examinations showed damaged restorations, gutta percha filling that are not hermetic and radiolucent on periapical. A successful endodontic retreatment premolar using rotary retreatment file and preparation with crown down technique using rotary progressive multiple tapering file, with comprehensive endo-prosthetic treatment using prefabricated fiber post and porcelain fused to metal crown. Conclusion: Clinical and radiographic evaluation after 6 months showed complete healing and good adaptation of the restoration. The outcomes of this case showed that failure of endodontic retreatment respond favorably to endodontic retreatment, with proper indication, prefabricated fiber post and porcelain fused to metal crown can provide an effective conservative and esthetic option for reinforcing endodontically treated teeth.

ABSTRACT Objective The objective of this study is to evaluate the vertical root fracture resistance of endodontically treated teeth obturated with – Tubli-Seal EWT/Gutta-percha, AH Plus/Gutta-percha, Epiphany SE sealer/Epiphany point. Study design Sixty-five single rooted premolars were decoronated and root length was 14 mm for each specimen. Fifty five teeth were enlarged up to ISO size 40 master apical file with stainless steel K-files using standardized preparation and remaining ten teeth were served as negative control. Then teeth were randomly assigned into different groups depending on sealer used for obturation as follows: Group 1 Negative control—no instrumentation was performed. Group 2 Positive control—gutta-percha with out the use of any sealer. Group 3 Experimental group—gutta-percha and Tubli-Seal EWT root canal sealer. Group 4 Experimental group—gutta-percha and AH Plus. Group 5 Experimental group—epiphany SE sealer and epiphany points. After 72 hours, the specimens were embedded in autopolymerizing resin leaving 7 mm of each root exposed and were subjected to fracture testing under universal testing machine at a crosshead speed of 1.0 mm per minute until the root fractured. Results were statistically analyzed using one-way ANOVA and independent t-test. Results Showed that Epiphany SE sealer/Epiphany points showed highest mean fracture resistance and Tubli-Seal EWT group showed the least fracture resistance of all the materials tested. There was no statistically significant difference among experimental groups. Conclusion Epiphany SE sealer/Epiphany points demonstrated highest fracture resistance values than the other materials tested and intact tooth had highest resistance against vertical root fracture. Clinical significance Epiphany SE sealer/Epiphany points may be one of the materials of choice in the endodontic treatment of teeth.

Root Fractures

INTRODUCTION: Following endodontic therapy, the development of root fracture(s) is considered to be a risk factor. It can be diagnosed accurately with the help of various radiographic aids.AIM: To assess the prevalence of horizontal and vertical root fractures among endodontically treated teeth among patients visiting a specialised tertiary care dental care clinic.METHODOLOGY: Patients suspected of having root fracture (due to endodontic treatment or non-endodontic treatment) were confirmed with the help of radiographic aids (IOPAR, OPG and occlusal radiographs). Root fractures due to endodontic treatment were then classified as horizontal and vertical root factures and analysed using the student’s t-test, ANOVA and odd’s ratio (OR). Data was analysed using SPSS version 21.0RESULTS: The study population comprised of 383 subjects. Males (207, 54%) formed a majority of the study population. Majority of fractures were seen in females [(162, 58.5%), endodontically treated teeth], while a slightly increased prevalence was seen among males (92, 86.8%) in non-endodontically treated teeth. A total of 277(72.3%) teeth were endodontically treated [155(55.9%) horizontal and 122(44.1%) vertical fracture], while 106(27.7%) were 155 non-endodontically treated teeth [63(59.4%) horizontal and 43(40.6%) vertical fracture]. A significance difference between horizontal and vertical root fractures [p=.005(t-test), p=.0025(ANOVA)] was seen. Odd’s ratio analysis revealed that horizontal fractures (OR=2.2) were more prone to develop as compared to vertical fractures.CONCLUSION: Owing to the fact that endodontically treated teeth are more brittle as compared to non-endodontically treated teeth, it is advised that the dental clinician should closely routinely follow- up endodontically treated teeth for signs of root fracture and confirm with a radiographical aid when such fractures are suspected.

A vertical root fracture (VRF) is a complex complication that usually leads to tooth extraction. The aim of this article is to review the prevalence, demography, distribution, diagnostic methods, etiology and predisposing factors, clinical features, radiographic characteristics and treatment strategies of VRFs in non-endodontically treated teeth (VRFNETT) and endodontically treated teeth (VRFETT). Search terms for each subject related to VRFNETT and VRFETT were entered into MEDLINE, PubMed and Google Scholar. Systematic reviews, retrospective cohort studies, demographic research, clinical studies, case reports and case series were reviewed. Most of the VRFs were found in patients older than 40 years old. Older populations were discovered in the non-endodontically treated VRF group when compared to the endodontically treated VRF group. Male patients were found at a greater prevalence than females in the non-endodontically treated VRF group. The initial occurrence of a VRF may accompany radiolucent lines within the root canal, unusual space between the canal wall and intracanal material, a widening of the PDL space along the periradicular surfaces, angular bony destruction, step-like bone defects, V-shaped diffuse bone defects, or root resorptions corresponding to the fracture line before the clear separation of the fractured fragment. The indicative clinical and radiographic signs of VRF included a coronally positioned sinus tract, deep-narrow periodontal defects, the displacement of a fractured fragment, periradicular radiolucent halos and the widening of the root canal space. Interestingly, VRFNETT are more often observed in the Chinese population. Some patients with multiple VRFs were observed, suggesting possible predisposing factors in genetics and tooth development. The management of a VRF usually involves a multidisciplinary approach. The common distribution and features of VRFNETT and VRFETT were elucidated to facilitate recognition and diagnosis. Besides extraction, variable therapeutic schemes, such as the repair of the VRF, root amputation and others reported in earlier literature, are available. A long-term prognosis study of the various therapeutic strategies is needed.

Abstract PURPOSE：This study aimed to investigate the biomechanical basis of vertical tooth fracture occurring in the mesial root of the mandibular first molar. METHODS：We used 3D finite elements to analyze the stress distribution and transient displacement of the mandibular first molar after occlusal surface wear and tooth tilt. Based on four degrees of wear within each of the surface wear and tooth tilt groups, eight models were established in addition to the control model. A simulated bite force of 200 N was loaded on the occlusal surface, and nonlinear finite element analysis was used to explore the biomechanical basis of vertical root fracture. RESULTS：When the distal tipping angle of the abrasion plane of the mandibular first molar increased from 5° to 15°, the angle between the instantaneous displacement contours and the long axis of the tooth decreased. Meanwhile, the mesial root was found to suffer the highest stress concentration, and the possibility of longitudinal root fracture was increased. CONCLUSION: By evaluating the biomechanical effect of tooth wear and occlusal loading, we are able to identify some clinical interventions that may prevent vertical tooth fracture.
