AIM: To investigate the attenuating effect of sirtuin 6 (SIRT6) on hypoxia-induced production of chemokine (C-C motif) ligand 2 (CCL2) by osteoblasts and the relevance of this action on the pathogenesis of periapical lesions. METHODOLOGY: SIRT6 was overexpressed in MC3T3-E1 murine osteoblasts by lentivirus-mediated gene transfer. The relationship between the anti-glycolytic/anti-oxidative activities of SIRT6 and its effect on hypoxia-induced CCL2 production were examined...

The overuse of antibiotics and the emergence of antibiotic-resistant bacterial strains is a global concern. This concern is also of importance in terms of the oral microbiota and the use of antibiotics to deal with oral and dental infections. The aim of this paper is to review the current literature on the indications and use of antibiotics and to make recommendations for their prescription in endodontic patients. Odontogenic infections, including endodontic infections, are polymicrobial, and in most cases, the prescription of antibiotics is empirical...

REVIEW
I F Persoon, W Crielaard, A R Özok
The role of bacteria in causing apical periodontitis has been widely established, while the role of other microorganisms is studied less thoroughly. This systematic review and meta-analysis reviewed the literature for the prevalence and diversity of fungi in root canal infections. An extensive literature search was done in the Cochrane databases, EMBASE, MEDLINE, LILACS, SciELO and Web of Science. Additional studies were identified from six endodontic journals, four main endodontic textbooks and references of relevant papers...

AIM: To assess the antibiotic prescribing patterns of South African dentists for patients undergoing endodontic treatment. METHODOLOGY: This study used data from 2013 health insurance claims submitted by South African oral health professionals to determine the antibiotic prescribing patterns related to endodontic treatment. A logistic regression model was used to test the fully adjusted statistical significance of the association between the exploratory variables (gender, age group, event type, abscess treatment, chronic health) and the dependent variable (antibiotic prescription)...

AIM: To evaluate ex vivo the effect of several simulated pulpal blood flow rates on the change in pulp chamber temperature during direct fabrication of a provisional restoration using a polymethylmethacrylate (PMMA) resin. METHODOLOGY: Fifteen noncarious human premolars were prepared for complete coverage restorations. A curved needle connected to a peristaltic pump simulated the pulp blood flow. Two K-type thermocouples connected to a digital thermometer were placed in the pulp chamber, and the assembly was placed in an incubator at 37 °C...

AIM: To determine if a CBCT volume can aid in the location of MB2 canals in maxillary molars. METHODOLOGY: This prospective clinical study involved 50 patients that needed RCT on a maxillary molar. The teeth where the MB2 was located upon access with the dental operating microscope received routine root canal treatment, and teeth where MB2 was not located had a CBCT volume made after instrumenting the located canals. At the second appointment, the clinician used the aid of the CBCT volume and troughing to attempt to locate MB2...

AIM: To evaluate the Ca(2+) -releasing, alkalizing, and apatite-like surface precipitate-forming abilities of a prototype tricalcium silicate cement, which was mainly composed of synthetically prepared tricalcium silicate and zirconium oxide radiopacifier. METHODOLOGY: The prototype tricalcium silicate cement, white ProRoot MTA (WMTA), and TheraCal LC (a light-cured resin-modified calcium silicate-filled material) were examined. The chemical compositions were analyzed with a wavelength-dispersive X-ray spectroscopy electron probe microanalyzer with an image observation function (SEM-EPMA)...

AIM: To perform multiparametric analysis of the effects of soy milk (SM), whole milk (WM), and Hank's balanced salt solution (HBSS) on the viability of fibroblasts (HGF). It also aimed to evaluate the influence of these solutions on bovine root dentine according to OH(-) and PO4(3-) on the surface. METHODOLOGY: The HGF cytotoxicity was determined according to the XTT, NR and SRB assays at 1, 3, and 6 h. Root dentine fragments were assessed by Fourier infrared spectrophotometer (FTIR) before and after immersion in the solutions for the same periods...

AIM: To characterize the pulp immune cell profile in the teeth of rats treated with zoledronic acid (ZA). METHODOLOGY: Male Wistar rats (n = 6 per group) received four intravenous infusions of ZA at doses of 0.04, 0.20 or 1.00 mg kg(-1) ZA or saline (control). On the 70th experimental day, they were euthanized. The first right molar was examined microscopically and submitted to toluidine blue reaction and immunohistochemical for CD68, tumour necrosis Factor (TNF)-α, interleukin (IL)-1β, inducible nitric oxide synthase (iNOS), nuclear factor kappa B (NF-kB) and IL-18 binding protein (IL-18 bp)...

AIM: To evaluate the influence of cone-beam computed tomography (CBCT) filters on diagnosis of simulated endodontic complications. METHODOLOGY: Sixteen human teeth, in three mandibles, were submitted to the following simulated endodontic complications: G1) fractured file; G2) perforations in the canal walls; G3) deviated cast post; G4) external root resorption. The mandibles were submitted to CBCT examination (I-Cat(®) Next Generation). Five oral radiologists evaluated the images independently with and without XoranCat(®) software filters...

AIM: To examine the effect of reduction of MTA particle size on dento-alveolar and osseous healing in dogs. METHODOLOGY: Root canals of 24 mandibular premolars in four 2-year-old beagles were prepared andfilled with gutta-percha and sealer. Two to four weeks later, during periapical surgery, the root-end cavity preparations in these teeth were filled with either gray ProRoot MTA or modified (reduced particle sizes with faster setting time) MTA. The animals were sacrificed four months later...

AIM: To examine the effect of inflammatory stimuli on the proliferation/migration of dental pulp stem cells by assessing the responses of stem cell-associated marker-expressing cells in rat incisors to lipopolysaccharide (LPS) stimulation in vivo. METHODOLOGY: The crowns of rat incisors were removed, and the coronal pulp chamber was instrumented. After haemostasis, an absorbent point soaked in LPS was inserted into the cavity, which was then sealed. At 3 h, 12 h, and 48 h after LPS application, pulp tissues were subjected to double-immunoperoxidase labelling using two of the antibodies against microtubule-associated protein 1B (MAP1B), CD146, and STRO-1...

AIM: To revaluate through re-audit the technical quality of undergraduate nonsurgical root canal treatment (RCTx) in a dental teaching hospital as a result of recommended changes to teaching practices. METHODOLOGY: The technical quality of undergraduate RCTx was evaluated radiographically after educational changes and the mandatory introduction of new technologies (nickel-titanium files, apex locators, greater taper gutta-percha points) in 182 root canals. Evaluation was based on four criteria: presence of voids, root canal filling termination (0-2 mm of radiographic apex), all roots filled and the prepared canal contained the original anatomy...

AIM: To evaluate the effect of several solvents on the weight of apically extruded debris and irrigant during retreatment using a novel agar gel model. METHODS: Orange oil, turpentine oil and chloroform were used as solvents. Eighty single straight rooted extracted human mandibular premolar teeth with a single root canal were divided into four groups (n=20).

The aim of this study was to systematically review and critically analyse the published data on the treatment outcome (primary outcome) and on the cleaning and disinfection of root canals (secondary outcomes) achieved by negative pressure irrigation as compared to syringe irrigation. An electronic search was conducted in EMBASE, LILACS, Pubmed, SciELO, Scopus, and Web of Knowledge using both free-text keywords and controlled vocabulary. Additional studies were sought through hand-searching of endodontic journals and of the relevant chapters of endodontic textbooks...

This systematic review investigated the failure rate of conventional single-unit restorations in root filled posterior permanent teeth. Two reviewers independently applied eligibility criteria, extracted data and assessed the quality of the evidence of each included study according to The Cochrane Collaboration's procedures for randomized control trials (RCTs) and the STROBE criteria for observational studies. The MEDLINE (via Ovid), EMBASE (via Ovid), Cochrane Oral Health Group Trials Register and CENTRAL (via Cochrane Library) databases were searched electronically (January 1993 to week 1, February 2015)...
