Continued root development of revascularized immature permanent necrotic teeth depends on whether the Hertwig’s epithelial root sheath survives in case of apical periodontitis/abscess. Severe pulp canal calcification (obliteration) by hard tissue formation might be a complication of internal replacement resorption or union between the intracanal hard tissue and the apical bone (ankylosis) in revascularized immature permanent necrotic teeth.

A maxillary lateral incisor with four root canals. International Endodontic Journal.AbstractAim  To describe the successful non‐surgical endodontic management of a permanent maxillary lateral incisor tooth with four root canals.Summary  Aberrant morphology of root canals can occur in any tooth, including maxillary lateral incisors. In the presented case, clinical examination and radiographs clearly depicted the presence of four root canals in a right maxillary lateral incisor. The differential diagnosis included fusion, gemination, dens invaginatus or a combination of these. The report emphasises the need for attention during root canal treatment of maxillary lateral incisors.Key learning points • Clinicians should be aware of the variabl...

Tricalcium silicate exhibited adequate physical properties and thus was shown to be a suitable replacement for the PC component in MTA. Bismuth oxide drastically increased the setting time of the test cements in phosphate‐containing solutions. Alternative radiopacifiers that do not retard the setting time need to be investigated.

Alteration in the inherent metallic and surface properties of nickel–titanium root canal instruments to enhance performance, durability and safety: a focused review. International Endodontic JournalAbstractThe expanded use of nickel–titanium (NiTi) rotary instruments in root canal procedures has led to the development of a wide variety of shapes, designs and applications. Root canal anatomy has not changed, however, and the same challenges exist in both initial treatment and the revision of unacceptable treatment. These challenges include application with high levels of achievement and low to no levels of adverse effects, such as instrument fracture, root canal wall ledging, dentine wall perforation and so forth.

Repair and regeneration in endodontics. International Endodontic Journal.AbstractThe ideal objective of treatment of established diseases, including irreversible pulpitis and apical periodontitis, is to achieve wound healing. Wound healing can result in repair or regeneration. The ultimate goal of wound healing is to restore the original architecture and biological function of the injured tissue or organ. Although humans are equipped with powerful innate and adaptive immune defence mechanisms, many intrinsic and extrinsic factors can affect wound healing. Complete regeneration following injury in humans can occur only in the pre‐natal foetus within 24 weeks of gestation. Post‐natal wounds including irreversible pulpitis or apical periodontitis always heal by rep...

Influence of pH changes on chlorine‐containing endodontic irrigating solutions. International Endodontic Journal.Chlorine‐containing solutions are used for broad disinfection purposes. Water disinfection literature suggests that their disinfectant action depends on pH values as this will influence the available free chlorine forms. Hypochlorous acid (HOCl) has been suggested to have an antimicrobial effect around 80–100 times stronger than the hypochlorite ion. The aim of this paper was to review the influence of pH changes on the efficacy of chlorine‐containing endodontic irrigating solutions.

The use of limited cone beam computed tomography in the diagnosis and management of a case of perforating internal root resorption. International Endodontic Journal.AbstractAim  To describe the use of cone beam computed tomography (CBCT) in the diagnosis and management of a maxillary lateral incisor with perforating internal root resorption (IRR).Summary  Root resorption is the loss of dentine or cementum as a result of osteoclastic cell action. IRR occurs exclusively as a result of pulpal inflammation. Until very recently, the diagnosis of internal and external resorptive defects has been limited to the information obtained from conventional radiographic techniques. This case report describes the use of CBCT in the diagnosis and treatment planning of a cas...

The use of cone beam computed tomography in the management of dens invaginatus affecting a strategic tooth in a patient affected by hypodontia: a case report. International Endodontic Journal.AbstractAim  To report on the use of cone beam computed tomography (CBCT) in the diagnosis and management of dens invaginatus.Summary  Chronic apical periodontitis of an invaginated maxillary lateral incisor was diagnosed in a patient suffering from hypodontia and awaiting active orthodontic therapy. Loss of the tooth would have complicated orthodontic treatment. Conventional periapical radiographs provided insufficient information about the nature of the invagination and its relation to the root canal to formulate an appropriate plan for treating the tooth.
