AIM: To assess the stability of NaOCl solutions when combined with a novel product for clinical use, Dual Rinse HEDP, which contains etidronate (1-hydroxyethane 1,1-diphosphonate). METHODOLOGY: Mixtures of NaOCl solutions with Dual Rinse HEDP were prepared so that they initially contained 5.0%, 2.5%, or 1.0% NaOCl, and always 9.0% of dissolved Dual Rinse HEDP powder per total weight. NaOCl solutions alone were used as controls. The stability of these solutions over 8 h was assessed in transparent borosilicate glass bottles at ambient temperature (23°C)...

AIM: To evaluate the effects of progressive apical enlargement on the amount of unprepared root canal surface area and remaining dentine thickness. METHODOLOGY: The root canals of 30 extracted mandibular incisors with Vertucci's type I configuration were instrumented with rotary HyFlex instruments (Coltene-Whaledent, Altstätten, Switzerland) up to 4 instruments larger than the first one that bound at the working length (WL). Teeth were scanned in a micro-computed tomography (micro-CT) device before canal preparation and after instrumentation with the 2(nd) , 3(rd) and 4(th) larger instruments...

REVIEW
S Eramo, A Natali, R Pinna, E Milia
The typical treatment for irreversibly inflamed/necrotic pulp tissue is root canal treatment. As an alternative approach, regenerative endodontics aims to regenerate dental pulp-like tissues using two possible strategies: cell transplantation and cell homing. The former requires exogenously transplanted stem cells, complex procedures and high costs; the latter employs the host's endogenous cells to achieve tissue repair/regeneration, which is more clinically translatable. This systematic review examines cell homing for dental pulp regeneration, selecting articles on in vitro experiments, in vivo ectopic transplantation models and in situ pulp revascularization...

REVIEW
H M A Ahmed, P M H Dummer
Understanding the normal anatomical features as well as the more unusual developmental anomalies of teeth, roots and root canals is essential for successful root canal treatment. In addition to various types of root canal configuration and accessory canal morphology, a wide range of developmental tooth, root and canal anomalies exist, including C-shaped canals, dens invaginatus, taurodontism, root fusion, dilacerations, palato-gingival grooves. There is a direct association between developmental anomalies and pulp and periradicular diseases that usually requires a multidisciplinary treatment approach to achieve a successful outcome...

AIM: To characterise chemical degradation of the principal constituents of dentine after exposure to NaOCl and EDTA using Infrared Spectroscopy (ATR-FTIR). METHODOLOGY: Ground dentine particles, from extracted permanent human molars, were passed through sieves of 38 to1000 μm to provide six size ranges. Portions (250 mg) of each size range were reacted with 5mL of 2.5% NaOCl for 2-10 minutes; or 17% EDTA for 5-1440 minutes. Powders larger than 75μm were also sequentially exposed to NaOCl/EDTA/NaOCl each for 10 minutes...
