Chronic root fractures are a relative frequent dental condition, occurring both in vital teeth and in teeth with root canal treatment, with a difficult and frustrating diagnosis. Two clinical forms are described: crown-root fractures with crown origin and vertical root fractures with root origin. The aim of the study was to determine the prevalence of the root fractured extracted teeth in two dental clinics with different profile [oral rehabilitation (OR) and endodontics (E)] and to present some particular aspects of the root fractures...

The loss of upper front dental elements causes functional and psychosocial problems to the affected individuals. In this case report, the treatment planning considered hard and soft tissue loss for a complex fixed partial denture (FPD) rehabilitation. The six-element, all-ceramic FPD was manufactured using a computer-aided design/computer-aided manufacturing system with zirconia framework, veneered with leucite-reinforced ceramic. Ceramic artificial gum was also produced to guarantee tooth-facial proportions as well as lip support, promoting both esthetics and phonetics...

Anatomical variations should be kept in mind in clinical and carefully looked for in radiographic evaluation during endodontic treatment of maxillary premolars. These teeth have highly variable root canal morphology. Although three separate roots in the maxillary first premolars have been reported, it is a rarity to find both the first and second premolars possessing three separate roots. This case report describes the diagnosis and endodontic management of maxillary first and second premolars with three canals and three separate roots...

In this second part of a diptych on bruxism, the focus is on the associations of this masticatory muscle activity with other sleep-related conditions. Its association with the obstructive sleep apnoea syndrome (OSAS) has been a particular object of study. Bruxism seems to play a protective role in OSAS, although the evidence for this is not yet conclusive. Apart from this possible positive consequence, bruxism also has several negative consequences, for which evidence is available to a greater or lesser extent...

INTRODUCTION: Recent reviews confirm a general lack of randomized, controlled clinical studies on the efficacy of regenerative endodontics in immature teeth affected by pulp and periapical diseases. Moreover, we have no evidence of the curative efficacy of collagen membranes used as scaffolds in regenerative endodontics. Here, we evaluated whether a Bio-Gide collagen membrane (Geistlich Pharma AG, Wolhusen, Switzerland) has efficacy in promoting dentin formation in regenerative endodontics...

Traumatized anterior teeth require quick functional and esthetic repair. Tooth fragment reattachment is a simple and conservative clinical procedure to restore fractured anterior teeth. Different techniques of reattachment include enamel beveling, "v-" shaped internal enamel and dentin grooves, external chamfer, over contouring, and by placing fiber post, all of which were invasive methods. This article describes a novel technique of reattachment using canal projectors for stabilizing fractured fragments followed by endodontic therapy and internal reinforcement with custom fiber post (everStick Post™, GC Corporation, Tokyo, Japan)...

INTRODUCTION: A thorough knowledge of the anatomic morphology of the root canal system is necessary for the long-term success of the root canal therapy. The occurrence of C-shaped root canal configuration is one such variation. Achievement of favorable prognosis after commencing root canal therapy in such teeth is one of the challenges imposed on the endodontist. Hence, we evaluated the healing occurring after endodontic therapy in patients with C-shaped root canals in mandibular molars...

Intorduction: Patients usually undergo orthodontic treatment for achieving ideal interocclusal relationship between the dental tissue and bony tissue along with improving the speech, mastication, and facial esthetic appearance. Literature quotes paucity in the studies evaluating the effect of orthodontic treatment on the periodontal health of endodontically treated teeth. Hence, we planned the present study to assess the effect of orthodontic treatment on the periodontal health of endodonti-cally restored tooth...

Endodontic treatment is mainly based on root canal disinfection and its failure may be motivated by microbial resistance. Endodontic therapy can be benefitted by host defense peptides (HDPs), which are multifunctional molecules that act against persistent infection and inflammation. This study aimed to evaluate the antimicrobial, cytotoxic and immunomodulatory activity of several HDPs, namely clavanin A, clavanin A modified (MO) and LL-37, compared to intracanal medication Ca(OH)2. HDPs and Ca(OH)2 were evaluated by: (1) antimicrobial assays against Candida albicans and Enterococcus faecalis, (2) cytotoxicity assays and (3) cytokine tumor necrosis factor (TNF)-α, monocyte chemoattractant protein (MCP)-1, interleukin (IL)- 1α, IL-6, IL-10 and IL-12 and nitric oxide (NO) production by RAW 264...

INTRODUCTION: The incidence of vertical root fracture in endodontically treated teeth increases with patient age. This study evaluated the microstructure, chemical composition, and mechanical properties of radicular dentin as a function of aging. METHODS: Single-rooted teeth were obtained from adult donors ranging from age 15 to older than 80 years. Beams were extracted from the middle third of the root and subjected to 4-point flexure to failure to evaluate strength of dentin in terms of donor age...

INTRODUCTION: Regenerative treatments in necrotic immature teeth are suggested as alternatives to conventional multiple or single-step apexification procedures. Although case reports and case series provide promising results, the treatment protocol is not yet fully established and regenerative procedure might fail. Once failure is encountered, the apexification treatment options still remain. METHODS: Repetition of the regenerative procedure after initial revitalization failure has not been suggested yet...

Dens invaginatus (DI) poses peculiar challenges in endodontic treatment of teeth because of distortion of pulpal space. A case of Oehlers type II DI with open apex and large periapical lesion is reported. The case was managed using cone-beam computed tomography (CBCT), operating microscope, platelet-rich fibrin (PRF), and Biodentine. A 15-year-old male patient presented with palatal swelling. Pulp sensibility testing of right maxillary lateral incisor was negative. Intraoral periapical digital radiograph revealed an Oehlers type II DI with open apex and periapical radiolucency...
