ABSTRACT

Background
Rheumatoid arthritis (RA) is an autoimmune disorder that usually affects joints and making them warm, painful, and swollen. The chief purpose of this study was to evaluate movements of mandible in geriatric patients suffering from RA with or without temporomandibular joint dysfunction.

Materials and methods
A total of 45 people were included in this study with age of 60 years and above. Partially or completely edentulous patients were divided into experimental and control group. Experimental group consists of 20 people suffering from arthritis and control group consists of 25 people without arthritis. Movements were recorded with or without prosthesis while mastication in both experimental and control group.

Results
Statistical evaluation of two studied groups showed decrease opening angle (p < 0.05) during mastication; however, insertion of new prosthesis showd a significant increase in values in both groups, with an increase in opening and closing angles.

Conclusion
Positive correlation was found between arthritis and movements of the mandible in older people suffering from RA.

Clinical significance
Patients suffering from RA are having restricted mandibular movements thus imposing an overall negative impact however; presence of prosthesis has been shown to enforce a positive effect on mandibular movement.

Authors: Agarwal Anand , Nanda Zinnie , Deore Rahul B , Rudagi Kavitarani , Baig Mirza Osman , Fareez Md Adil 
Published: September 2017

ABSTRACT

Aim
The aim of this study was (i) to evaluate the formation of air bubbles in the apical region of root canal (apical vapor lock) during syringe irrigation, using cone beam computed tomography (CBCT) and (ii) comparative evaluation of the elimination of an established vapor lock by EndoActivator, ultrasonics, and manual dynamic agitation (MDA), using CBCT.

Materials and methods
A total of 60 extracted human singlerooted teeth were equally divided into three groups of 20 teeth each. The samples were decoronated 17 mm from the apex, cleaned, and shaped to size F4 Protaper using 3% sodium hypochlorite. Samples were irrigated with 3% sodium hypochlorite + cesium chloride radiopaque dye, and preoperative CBCT images were obtained. After formation of apical vapor lock in the scanned teeth, EndoActivator (group I), passive ultrasonic irrigation (group II), and MDA with K-file (group III) were performed and the teeth were again placed in CBCT scanner and results analyzed using the chi-square test.

Results
The apical vapor lock was formed in all the samples. Out of the 20 teeth in each group, the apical vapor lock was eliminated in 18 samples of EndoActivator group (90%), 16 samples of ultrasonic group (80%), while it was eliminated in 10 samples by MDA (50%).

Conclusion
It is concluded that (1) apical vapor lock is consistently formed during endodontic irrigation in closed canal systems and (2) sonic activation performs better than the ultrasonics and MDA in eliminating the apical vapor lock, with statistically significant difference between all the three groups (p < 0.05).

Clinical significance
The results suggest that the apical vapor lock (dead water zone) is consistently formed during endodontic irrigation which impedes irrigant penetration till the working length, thereby leading to inefficient debridement. Hence, to eliminate this vapor lock, techniques, such as sonics or ultrasonics should be used along with the irrigant after shaping and cleaning of the root canal.

ABSTRACT

Aim
The aim of this study was to evaluate the efficacy of Axiostat Hemostatic Dental dressing in achieving hemostasis postextraction and determining its effect on pain and healing of the extraction wound, compared with control, i.e., conventional method of extraction in patients on oral antiplatelet therapy.

Materials and methods
Totally, 40 patients on oral antiplatelet drugs were included in the study and overall 80 extractions were done applying split mouth study design, without altering patient's drug regime. Extraction sites were divided into two groups: Group I received Axiostat Hemostatic Dental Dressing (study site), and group II received conventional method; pressure pack with sterile gauze under biting pressure followed by suturing if required (control site) was used to attain hemostasis.

Results
Extraction sites treated with Axiostat Hemostatic Dressing achieved hemostasis earlier (mean 1 minute 13 seconds) compared with control sites (mean = 14 minutes 1 second), which was also statistically significant (p < 0.001). Postoperative pain was considerably lower and significantly better healing was seen in the study group (p < 0.001) compared with the control.

Conclusion
Axiostat demonstrated to be an effective hemostatic agent that considerably lessens the bleeding time in patients on oral antiplatelet drugs postextraction. In addition, it even offered minimal postoperative pain and improved healing of the extraction wound. On comparing the results of this study with our study on HemCon Dental Dressing, Axiostat Dental Dressing (ADD) is found to be as effective and at par in achieving hemostasis in patients on oral antiplatelet therapy.

Clinical significance
The past few decades have seen an upsurge in use of low-dose aspirin either alone or in combination with other drugs. When these patients require dental/maxillofacial treatment, earlier concept of stopping these medications is associated with increased risk of thromboembolic event. The present study highlights an alternative approach using ADD which aids in quick hemostasis, accentuates healing, and reduce postoperative pain.

Published: September 2017

ABSTRACT

Aim
The aim of this study was to test the effect of varying alcohol concentrations of various commercially available mouthwashes on force decay of elastomeric chains in prestretched and unstretched condition.

Materials and methods
A total of five specimen groups were tested with a total sample size of 180 specimens. A specimen is described as a three-link, short module, clear elastomeric chain (3M Unitek, Ortho Plus, Ortho Organizer). The control and test groups were independently submerged in separate 37°C artificial saliva to simulate the oral conditions. Effects of different solution groups and time (initial, 1, 7, 14, 21, and 28 days) on three different elastomeric chains and force (cN) are analyzed with two-way analysis of variance; pair-wise comparisons are done by t-test.

Results
Higher mean force was recorded initially followed by 24 hours >7 days >14 days >21 days and 28 days respectively. The difference in mean force decay among the different time intervals was found to be statistically significant (p < 0.001). Among the different solutions, higher mean force was recorded in 21.6% alcohol mixture > Listerine 8.38% > Wokadine > alcohol mixture 8.38% > artificial saliva.

Conclusion
In conclusion, alcohol-containing mouth rinses cause an increase in force decay of elastomeric chain over time.

Clinical significance
These mouth rinses are commonly recommended during orthodontic treatment. The orthodontist can know better that the alcohol content of the mouth rinses and the structural and molecular modification results in the decay of elastomeric chain.

ABSTRACTAimTo assess caries prevalence among 6- to 9-year-old female children in Riyadh, Kingdom of Saudi Arabia and compare between results based on nationality and age levels.Materials and methodsA total of 17,891 female students from 120 public female elementary schools in Riyadh city were examined according to the World Health Organization (WHO) diagnostic criteria. The decayed [dt], missing due to caries [mt], and filled [ft] primary teeth (dmft) index and its components were measured. One-way analysis of variance (ANOVA), Student'st-test, and Chi-squared test were used to determine the significance differences, at α = 0.05.ResultsThe overall mean [dt] for all children was 3.89 [standard deviation (SD) 3.38], which increased to 5.0 (SD 3.02) when excluding children without active caries. The mean dmft was 5.69 (SD 4.0). However, excluding children with dmft = 0, the mean dmft was raised to 6.41 (SD 3.65). The caries prevalence was 88.82%. The non-Saudi children showed slightly higher values compared with Saudi children. However, statistically, there were only significant differences in values of [dt] mean, dt = 0, and [ft] mean (p < 0.05). The dmft index was higher for 7- to 8-year-old group (5.81, SD 3.98) followed by the 8- to 9-year-old group (5.79, SD 3.79) and the 6- to 7-year-old group (5.47, SD 4.18). However, there were no statistically significant differences (p > 0.05) between 7- to 8-year-old and 8- to 9-year-old children. The 6- to 7-year-old children were statistically different from the 7- to 8 and 8- to 9-year-old children.ConclusionThe dental caries prevalence among the study population was high, with the majority of children having untreated caries. This highlights the need for initiating deliberate community-based preventive measures for improvement in public health education and services provided.How to cite this articleAlshiha SA, Alwayli HM, Hattan MA, Alfraih YK, Alamri AA, Aldossary MS.

Published: September 2017

ABSTRACT
Congenitally missing teeth are one of the most common dental anomalies which may be termed as dental agenesis. Polygenesis, the formation of one or more supernumerary teeth, occurs much less frequently than agenesis. Hypodontia and hyperdontia are regarded as the opposite dental developmental anomalies. However, their simultaneous presence in the same individual is a rare condition. A case of concomitant hypo-hyperdontia (CHH) is presented here, wherein a 20-year-old female has missing mandibular central incisors, maxillary second molars, and all the third molars. In addition, she has a malformed supernumerary tooth in the mandibular left anterior region. Documentation of such rare case reports is necessary as it helps in minimizing the clinicians' challenge in diagnosing such cases and thus helpful in providing a multidisciplinary approach in treating such patients.

Rainfall drives atmospheric ice-nucleating particles in the coastal climate of southern Norway

Published: September 2017

Abstract. Ice-nucleating particles (INPs) active at modest supercooling (e.g. −8 °C; INP−8) can transform clouds from liquid to mixed phase, even at very small number concentrations (< 10 m−3). Over the course of 15 months, we found very similar patterns in weekly concentrations of INP−8 in PM10 (median  =  1.7 m−3, maximum  =  10.1 m−3) and weekly amounts of rainfall (median  =  28 mm, maximum  =  153 mm) at Birkenes, southern Norway. Most INP−8 were probably aerosolised locally by the impact of raindrops on plant, litter and soil surfaces. Major snowfall and heavy rain onto snow-covered ground were not mirrored by enhanced numbers of INP−8. Further, transport model calculations for large (> 4 m−3) and small (< 4 m−3) numbers of INP−8 revealed that potential source regions likely to provide precipitation to southern Norway were associated with large numbers of INP−8. The proportion of land cover and land use type in potential source regions was similar for large and small numbers of INP−8. In PM2. 5 we found consistently about half as many INP−8 as in PM10. From mid-May to mid-September, INP−8 correlated positively with the fungal spore markers arabitol and mannitol, suggesting that some fraction of INP−8 during that period may consist of fungal spores. In the future, warmer winters with more rain instead of snow may enhance airborne concentrations of INP−8 during the cold season in southern Norway and in other regions with a similar climate.

Constraining Balmer Alpha Fine Structure Excitation Measured in Geocoronal Hydrogen Observations

Published: September 2017

AbstractCascade contributions to geocoronal Balmer α airglow line profiles are directly proportional to the Balmer β/α line ratio and can therefore be determined with near simultaneous Balmer β observations. Due to scattering differences for solar Lyman β and Lyman γ (responsible for the terrestrial Balmer α and Balmer β fluorescence, respectively), there is an expected trend for the cascade emission to become a smaller fraction of the Balmer α intensity at larger shadow altitudes. Near‐coincident Balmer α and Balmer β data sets, obtained from the Wisconsin H alpha Mapper Fabry‐Perot, are used to determine the cascade contribution to the Balmer α line profile and to show, for the first time, the Balmer β/α line ratio, as a function of shadow altitude. We show that this result is in agreement with direct cascade determinations from Balmer α line profile fits obtained independently by high‐resolution Fabry‐Perot at Pine Bluff, WI. We also demonstrate with radiative transport forward modeling that a solar cycle influence on cascade is expected, and that the Balmer β/α line ratio poses a tight constraint on retrieved aeronomical parameters (such as hydrogen's evaporative escape rate and exobase density).
Elves Accompanying Terrestrial Gamma Ray Flashes
Authors: Liu Ningyu , Dwyer Joseph R. , Cummer Steven A. 
Published: September 2017

AbstractThis paper reports a modeling study of the optical phenomenon in the lower ionosphere known as elves that may accompany terrestrial gamma ray flashes (TGFs). Recent research has indicated that the in‐cloud (IC) discharge processes, termed energetic in‐cloud pulses (EIPs), associated with some TGFs can produce a current moment waveform with a peak of hundreds of kA km and a duration of 10 μs. Simulations using the source current moment waveform associated with a Fermi TGF indicate that the radiated electric field at ionospheric altitudes reaches a few times the threshold electric field to excite the optical emissions. A bright elve is therefore induced, with the intensity reaching tens of Megarayleigh, comparable to the brightest elves caused by cloud‐to‐ground lightning. Because of the strong electromagnetic field radiated, significant blue emissions from the second positive band system of N2 and the first negative band system of N
are excited, besides the dominant red emissions from the first positive band system of N2. The elves caused by EIPs with durations of ∼10 μs are elve doublets. For EIPs of longer durations, for example, 30–40 μs, elve multiplets greater than two can be produced. We conclude that elves can be produced by an IC lightning process previously unconnected to elves and that at least some TGFs should have accompanying optical signatures in the lower ionosphere. In addition, TGFs of short durations are more likely to have accompanying elves, because their source currents vary more rapidly.
The Effect of Water Column Resonance on the Spectra of Secondary Microseism P Waves

Published: September 2017

AbstractWe compile and analyze a data set of secondary microseismic P wave spectra that were observed by North American seismic arrays. Two distinct frequency bands, 0.13–0.15 Hz and 0.19–0.21 Hz, with enhanced P wave energy characterize the data set. Cluster analysis allows to classify the spectra and to associate typical spectral shapes with geographical regions: Low‐frequency‐dominated spectra (0.13–0.15 Hz) are mostly detected in shallower regions of the North Atlantic and the South Pacific, as well as along the Central and South American Pacific coast. High‐frequency‐dominated spectra (0.19–0.21 Hz) are mostly detected in deeper regions of the northwestern Pacific and the South Pacific. For a selected subset of high‐quality sources, we compute synthetic spectra from an ocean wave hindcast. These synthetic spectra are able to reproduce amplitude and shape of the observed spectra, but only if P wave resonance in the water column at the source site is included in the model. Our data sets therefore indicate that the spectral peaks at 0.13–0.15 Hz and 0.19–0.21 Hz correspond to the first and second harmonics of P wave resonance in the water column that occur in shallower ocean depths (<3,000 m) and in the deep ocean (∼5,000 m), respectively. This article demonstrates the important effect of water column resonance on the amplitude and frequency of P waves that are generated by secondary microseisms and that the amplitude of high‐quality sources can be predicted from ocean wave hindcasts within a factor of 0.4–6.

AbstractControl of defect densities at insulator/GaxIn1−xAs interfaces is essential for optimal operation of various devices like transistors and infrared detectors to suppress, for example, nonradiative recombination, Fermi‐level pinning, and leakage currents. It is reported that a thin InOx interface layer is useful to limit the formation of these defects by showing effect of InOx on quantum efficiency of Ga0.45In0.55As detector and on photoluminescence of GaAs. A study of the Al2O3/GaAs interface via hard X‐ray synchrotron photoelectron spectroscopy reveals chemical structure changes at the interface induced by this beneficial InOx incorporation: the InOx sheet acts as an O diffusion barrier that prevents oxidation of GaAs and concomitant As bond rupture.
Regioselective Epoxidations by Cytochrome P450 3A4 Using a Theobromine Chemical Auxiliary to Predictably Produce N‐Protected β‐ or γ‐Amino Epoxides
Authors: Polic Vanja , Cheong Kin Jack , Hammerer Fabien , Auclair Karine 
Published: September 2017

AbstractN‐Protected β‐ and γ‐amino epoxides are useful chiral synthons. We report here that the enzyme cytochrome P450 3A4 can catalyze the formation of such compounds in a regio‐ and stereoselective manner, even in the presence of multiple double bonds or aromatic substituents. To this end, the theobromine chemical auxiliary is used not only to control the selectivity of the enzyme, but also as a masked amine, and to facilitate product recovery. Theobromine predictably directed epoxidation at the double bond of the fourth carbon from the theobromine group. Unlike with most catalysts, the selectivity did not depend on electronic or steric factors but rather on the position of the olefin relative to the theobromine group.magnified image
