Published: July 2018

AbstractAimTo examine the contribution of perivascular cells expressing αSMA to reactionary dentinogenesis.MethodologyAn inducible, Cre‐loxP in vivo fate‐mapping approach was used to examine the contribution of the descendants of cells expressing the αSMA‐CreERT2 transgene to reactionary dentinogenesis in mice molars. Reactionary dentinogenesis was induced by experimental mild injury to dentine without pulp exposure. The Student's t test was used to determine statistical significance at *P ≤ 0.05.ResultsThe lineage tracing experiments revealed that mild injury to dentine first led to activation of αSMA‐tdTomato+ cells in the entire pulp chamber. The percentage of areas occupied by αSMA‐tdTomato+ in injured (7.5 ± 0.7%) teeth were significantly higher than in teeth without injury (2 ± 0.5%). After their activation, αSMA‐tdTomato+ cells migrated towards the site of injury, gave rise to pulp cells and a few odontoblasts that became integrated into the existing odontoblast layer expressing Col2.3‐GFP and Dspp.ConclusionMild insult to dentine activated perivascular αSMA‐tdTomato+ cells giving rise to pulp cells as well as a few odontoblasts that were integrated into the pre‐existing odontoblast layer.

AbstractAimTo evaluate the bacterial reduction achieved by WaveOne Gold (Dentsply Sirona Endodontics, Ballaigues, Switzerland), Hyflex EDM (Coltene‐Whaledent, Altstätten, Switzerland), and XP‐endo Shaper (FKG Dentaire SA, La Chaux‐de‐Fonds, Switzerland) in canals infected with Enterococcus faecalis. The null hypothesis (H0) was that there would be no difference amongst the NiTi systems in reducing the root canal bacterial load.MethodologySeventy‐four mandibular premolar teeth with straight and round root canals were selected. Sixty‐two root canals were contaminated with E. faecalis for 4 weeks and subjected to mechanical preparation with one of three single‐file NiTi rotary systems (WaveOne Gold, Hyflex EDM, and XP Endo Shaper). Twelve non‐contaminated root canals were used as negative controls. Bacterial samples were collected with sterile paper points (Dentsply Sirona Endodontics) before and after rotary instrumentation to quantify the bacterial load. Five roots from each instrumentation group were evaluated topographically from the coronal, middle and apical thirds by SEM. The bacterial reduction was calculated and analysed statistically by the Kruskal–Wallis and Dunn post hoc tests, all at 5% significance.ResultsThe samples taken before instrumentation showed approximately 9.64 log CFU bacterial load. Instrumentation with the Hyflex EDM and XP‐endo Shaper resulted in significantly greater bacterial reduction than those with WaveOne Gold (P = 0.00). All specimens had bacterial growth. SEM images supported the CFU/mL data. Thick and dense debris was observed in WaveOne Gold samples. Instrumentation resulted in the disruption of the biofilm‐like structure, and both areas of clean and open dentinal tubules and areas with thick debris were observed in Hyflex EDM and XP‐endo Shaper samples.ConclusionsInstrumentation in straight and round canals of premolar teeth with the Hyflex EDM and XP‐endo Shaper resulted in significantly greater bacterial reduction than WaveOne Gold. No instrumentation system rendered root canals completely free from bacteria.

AbstractThe lead cobalt titanate (PCT) nanoparticles with varying cobalt concentration from 0.2 to 0.8 were synthesized via sol‐gel technique. Furthermore, these samples were undergone microwave heat treatment at 1023 K for ¾ hours. The powder diffraction study established the structural transformation of PCT nanoparticles from tetragonal (T) to rhombohedral (R) phases at higher cobalt contents. The surface morphology was examined by transmission electron microscope. Moreover, the ferroelectric property was elucidated by means of polarization versus electric field loop with varying temperature. The results revealed that 0.2, 0.6, and 0.8 compositions established the real ferroelectric behavior, whereas 0.4 composition attributed the banana shape hysteresis loop revealing high lossy dielectric material.
Metastatic sigmoid colon adenocarcinoma and tumour‐related sarcoid reaction
Authors: De Gregorio Michael , Brett Andrew J. 
Published: July 2018

AbstractThe association between malignancy and tumour‐related sarcoid reaction is well documented, characterised by non‐caseating granulomatous disease in haematological and solid malignancies. Its occurrence in colon cancer is rare and of unclear clinical significance. Herein, we present a case report of a 32‐year‐old woman diagnosed with concurrent metastatic sigmoid colon adenocarcinoma and pulmonary granulomatous disease suggestive of a tumour‐related sarcoid reaction.

BackgroundLimited data is available on variables influencing the survival of composite restorations in primary teeth.AimThis retrospective university‐based study assessed the survival and risk factors associated with failures of resin composite restorations performed in primary teeth.DesignThe sample was composed of 961 restorations from records of 337 patients (178 girls and 159 boys) attended in a university dental clinic. The restorations’ longevity up to 48 months of follow‐up was assessed using the Kaplan–Meier survival test. Multivariate Cox regression analysis with shared frailty was used to evaluate the factors associated with failures (P < 0.05).ResultsMean survival time was 41.5 months (95% CI: 39.7–43.3), with 70.6% of the restorations surviving after 48 months of evaluation. The overall annual failure rate up to 48 months follow‐up was 8.3%. Restorations placed in lower arch had lower survival rate than those in upper arch (HR: 1.82, 95% CI: 1.02–3.28). Restorations involving two or more surfaces had more risk of failure than restorations placed in cavities involving only one surface (HR: 2.55 95% CI: 1.34‐ 4.83). Girls had less risk of failure in their restorations (HR: 0.43, 95% CI: 0.19–0.96).ConclusionIndividual and dental variables such as gender, arch type and number of restored surfaces were associated with failure of composite restorations performed in children under daily life clinical environment.

Published: July 2018

BackgroundThere is a paucity of evidence about cognitive behaviour therapy in the management of dentally anxious children.AimTo systematically review evidence of the effectiveness of cognitive behaviour therapy for children with dental anxiety or dental phobia.DesignClinical trial registries, grey literature, and electronic databases, including The Cochrane Library, EMBASE, PubMed, Scopus, Web of Science, LILACS/BBO, and PsycINFO, were searched (April 2018). The reference lists of relevant studies were hand‐searched. Randomised controlled trials that evaluated the effects of cognitive behaviour therapy on dental anxiety or on acceptance of dental treatment in dental patients up to 18 years were included. Two trained and calibrated reviewers performed the study selection and risk of bias assessment. The quality of the evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE).ResultsSix studies with a total of 269 patients, aged 41 months to 18 years, were included. Cognitive behaviour therapy decreased level of anxiety compared to control groups and improved cooperation/behaviour, although the quality of the evidence was low.ConclusionsCognitive behaviour therapy produces better anxiety reduction than diverse behavioural management techniques but the evidence was of low quality and further studies in children are needed.

Published: July 2018

AbstractForeign body in food is a matter of concern in food industry as it determines the safety and quality of the product. This issue leads to anxiety as it is hazardous if it is accidentally being consumed. Therefore, foreign body detection is urgently needed. Noninvasive techniques are attractive as they can be used to evaluate without altering the originality of the food products in terms of ingredient and structure. With the growing interest in this subject, this article reviews the development of noninvasive techniques including X‐ray, thermal imaging, near‐infrared spectroscopy, hyperspectral imaging, ultrasonic, and terahertz. The principle and application of each technique are elaborated. The performances and limitations from previous studies in several types of food applications are analyzed. In addition, future trends and challenges encountered with these techniques are highlighted. It is envisaged that the information gathered in this article will be a valuable source of information for researchers working in this topic.Practical applicationsThe existence of foreign bodies in food causes degradation of their quality and safety. The implementation of the noninvasive technique as a monitoring tool have received an encouraging response from the manufacturers which endeavors to maintain their credibility and reputation. This review serves to provide an up‐to‐date development on the noninvasive technique for detecting foreign bodies which is useful for academicians and researchers especially from the food processing industries.

AbstractAimThe aim of the present study was to investigate the tissue generated after regenerative endodontic procedure (REP) in the root canal space of an immature mandibular second premolar with pulp necrosis and chronic apical abscess using cone‐beam computed tomographic (CBCT) and histological methods.MethodsREP was performed in an immature mandibular second premolar. At the 3‐year follow up, CBCT scans were taken to evaluate the outcome of treatment. As the tooth was not restorable to function, it was extracted and processed for histological examination.ResultsCBCT showed a reduction in size of the periradicular radiolucency, with a marginal increase in root length. Apical closure and thickening of the root canal walls were apparent. Histologically, the root canal space was filled with minimally‐inflamed fibrous connective tissue. Some cementum‐like mineralized connective tissue was evident on the internal canal walls. The apical third showed cementum‐like deposits at the apex and the outer canal walls, without dentin formation.ConclusionsThe present study of a structurally‐failed tooth with prior REP demonstrates that the tissue formed within the root canal space was fibrous connective tissue with cementum‐like deposition in the canal space. No evidence of dentin‐ or pulp‐like tissue was found.

AbstractAlthough the form‐function relation of muscles and tendons has been studied extensively, little in vivo data exist on the musculotendon properties of the gastrocnemius complex in dogs. Using a combination of ultrasound and 3D motion tracking, musculotendon parameters were obtained in vivo from the lateral gastrocnemius muscle and the gastrocnemius tendon in nine healthy Labrador Retrievers. These parameters include musculotendon length and excursion potential, tendon slack length, muscle belly length, muscle fibre length, pennation angle and architectural index. This study also examined the variation of muscle and tendon length contributions to musculotendon length, as well as the relation between musculotendon excursion potential and muscle fibre length or tendon length. To facilitate comparison between dog breeds, the femur length as a potential scaling parameter was examined. In the Labrador gastrocnemius musculotendon complex, the tendon contributes 41% (± 9%) of musculotendon length. In longer musculotendon complexes, the contribution of the muscle belly increases while the tendon contribution decreases. Longer muscle belly and musculotendon complexes were, however, associated with shorter muscle fibres. No significant relations were found between musculotendon excursion potential and muscle fibre length or tendon slack length, and femur length did not prove to be a reliable scale factor for the length‐related musculotendon parameters examined in this study. Longer musculotendon complexes exhibit relatively longer muscle bellies, which are in turn associated with shorter muscle fibre lengths. This trade‐off between gastrocnemius muscle belly length and muscle fibre length might have the advantage that muscle volume stays constant regardless of the length of the limbs.
Differences in Internalizing Symptoms Anticipate Adolescent Friendship Dissolution

Published: July 2018

This study examined the degree to which internalizing symptoms predict adolescent friendship instability. A total of 397 adolescents identified 499 same‐sex reciprocated friendships that originated in the seventh grade (M = 13.18 years). Discrete‐time survival analyses were conducted with Grade 7 peer, teacher, and self‐reports of internalizing symptoms as predictors of friendship dissolution across Grades 8–12. Differences between friends in depressive symptoms, anxiety symptoms, and (for boys only) submissiveness predicted subsequent friendship dissolution. Individual levels of these variables did not predict friendship dissolution, even at extreme or clinical levels. The findings suggest that friendship instability arising from internalizing problems stems from dissimilarity between friends rather than the presence of psychopathological symptoms on the part of one friend.

Published: July 2018

AbstractFamily Medicine Groups (FMGs) are the most recently developed primary care organizations in Quebec (Canada). Nurses within FMGs play a central role for patients with chronic diseases (CD). However, this complex role and the nursing activities related to this role vary across FMGs. Inadequate knowledge of nursing activities limits the implementation of exemplary nursing practices. This study aimed to describe FMG nursing activities with patients with CD and to describe the facilitators and barriers to these activities. A multiple‐case study was performed with ten nurses practicing among patients with CD in FMGs. Five data sources were used to provide an in‐depth description of nursing activities and the facilitators and barriers to the development of these activities. After qualitative data analysis, findings show that nursing activities are clustered into five domains: Global assessment of the patient, Care management, Health promotion, Nurse–physician collaboration, and Planning services for patients with CD. Activities vary depending on contextual factors identified in each case. This multiple‐case study provides a clear description of nursing activities with patients with CD. There is a need for improved nursing activities and expertise in domains of activities that are less present in FMGs, such as case management and interprofessional collaboration.

Published: July 2018

AbstractBackgroundInfantile hemangiomas with minimal or arrested growth are vascular tumors with a proliferative component involving < 25% of their total surface area. They are commonly described as localized lesions and are mainly located on the lower body. Little has been described about segmental forms on the face and their associations with PHACE syndrome.MethodsWe carried out a multicenter, retrospective, case‐series study involving 5 hospitals in Spain. Information was collected on cases of PHACE syndrome featuring infantile hemangiomas with minimal or arrested growth.ResultsThe frontotemporal and maxillary areas were the most frequently involved sites in our series. The upper eyelid and upper lip were the 2 locations most frequently associated with proliferation and ulceration. Four patients experienced spontaneous resolution, and the rest had a very good cosmetic outcome with oral treatment. Cerebral and cervical arterial anomalies were the most frequent extracutaneous findings associated with PHACE, followed by cerebral and ocular anomalies. Some unique associated disorders were fructose intolerance and retinoblastoma.ConclusionWe present the largest case series of segmental facial infantile hemangiomas with minimal or arrested growth in PHACE syndrome and emphasize the importance of recognizing these lesions in early infancy, because they can indicate PHACE syndrome. The data presented suggest that infantile hemangiomas with minimal or arrested growth–associated PHACE syndrome does not seem to differ significantly from PHACE syndrome with classic infantile hemangiomas, and thus the same recommendations for diagnosis, management, and therapy should be followed. Future studies with more patients could contribute to enlighten this specific subset.
Pedagogical challenges in teaching ESOL/Multilingual writers in theological education
Authors: Yaghjian Lucretia B. 
Published: July 2018

AbstractA theological school's international students contribute to and are constitutive of its diversity. Yet while research on diversity in theological education is flourishing, the pedagogical challenges of international ESOL (English for Speakers of other Languages) theological students and of their teachers have received scant attention. This article probes the pedagogical challenges of international student writers in theological schools, and of their teachers and tutors, by (1) reflecting on those challenges, their context, and responses to them; (2) connecting contemporary theories of ESOL language learning with the practice of teaching and tutoring non‐native English writers in a theological context; and (3) proposing a discipline‐driven, writing‐centered ESOL pedagogy that I call “Writing Theology as a Common Language.” See as well “Responses to Lucretia B.

The Baltimore Mural Project: An approach to threshold concepts in religious studies
Authors: Morales Harold , Barnes Mark 
Published: July 2018

AbstractThe Baltimore Mural Project (BMP) seeks to connect religious studies education to the growing literature on threshold concepts in order to address bottleneck areas in student learning. The project is designed for undergraduate service courses comprised of mostly non‐majors: for example, world religions. Students in these courses often struggle to understand and apply the discipline's unique approaches to the study of religion (i.e. its threshold concepts). Rather than merely memorize certain facts about a religious tradition's myths [or world forming stories], rituals [or embodied disclosures], materials, and so on... students are asked to apply threshold concepts related to religion, art, and the social good to the study of murals in Baltimore. Through a series of project elements (including: field work, photography, digital geomapping, and quantitative, qualitative, and archival research) the BMP helps students who struggle with threshold concepts in religious studies by creatively connecting the more conventional aspects of world religions courses to social justice issues related to mural art in Baltimore. By experientially helping students to make these connections, they are able to find creative routes through otherwise hindering barriers to their learning in religious studies.
Moral injury and the ethics of teaching tainted legacies
Authors: Guth Karen V. 
Published: July 2018

AbstractCases like that of John Howard Yoder – a pacifist theorist who perpetrated sexual violence – raise difficult questions about teaching material implicated in traumatic pasts. This paper argues that “moral injury” provides a useful framework for understanding the dynamics of teaching prominent cases of tainted legacies like Yoder's and for developing best pedagogical practices across the field of religious ethics. The moral injury framework empowers students to think critically and self‐reflectively about authority, conceptions of the good, the various stakes for different persons and communities in social issues, and the need for moral repair. It establishes the importance of professor and student preparation; propels students into the moral questioning and analysis that constitutes “ethics”; draws attention to the connections between and intersectionality of various moral problems while also attending to important moral distinctions; and affords opportunities to study individual and institutional efforts at moral repair.
Using virtual reality and 360‐degree video in the religious studies classroom: An experiment
Authors: Johnson Christopher D. L. 
Published: July 2018

AbstractThe advent of relatively inexpensive 360‐degree cameras and virtual reality (VR) headsets brings new possibilities to the study of religion by allowing students to become virtually immersed in distant religious environments at very little cost. These tools can serve as the basis for assignments that help to engage students and meet core learning outcomes such as empathetic understanding and ethnographic analysis of religious place, ritual, and behavior in light of theories of religion. This article describes and reflects on the experimental incorporation of these technologies in two sections of an introductory religious studies course at a small two‐year campus in the University of Wisconsin System.
