Robotic Process Automation for Auditing
Authors: Moffitt Kevin C. , Rozario Andrea M. , Vasarhelyi Miklos A. 
Published: August 2018

ABSTRACT
The advent of Robotic Process Automation (RPA) has the potential to disrupt the traditional audit model. With its capability to automate rules-based tasks that are repetitive and manual, RPA is expected to repurpose the role of the auditor by replacing perfunctory tasks and emphasizing higher order thinking skills that will eventually lead to enhanced audit quality. This editorial envisages the future of audit by introducing the concept of RPA and describing its usage in auditing. Moreover, considerations for RPA-based audits and a series of research questions are presented with the objective to create a dialogue in this evolutionary area.

ABSTRACT

Objective:
To evaluate light transmittance, surface roughness, and flexural modulus of copolyester retainer material after long-term exposure to different cleaning methods.

Materials and Methods:
Standardized copolyester retainer specimens (ACE) were subjected to seven chemical cleaning solutions for 6 months: Invisalign cleaning crystals, Retainer Brite, Polident, Listerine mouthwash, 2.5% acetic acid, 0.6% NaClO, and 3% H2O2. Seventy specimens (n = 10 per method, 50.8 mm × 12.7 mm × 1.0 mm) were exposed to the different solutions twice a week for 2 minutes or according to manufacturer's instructions and stored in artificial saliva at 37°C. Another group of specimens (n = 10) was brushed with a standardized toothbrushing machine for 2 minutes twice a week. At baseline and 6 months, light transmittance, surface roughness and flexural modulus of the specimens were quantified using spectrophotometry, profilometry, and three-point bend testing, respectively. Qualitative assessment was performed using scanning electron microscopy (SEM). Statistical analyses were accomplished at a significance level of .05.

Results:
The results indicated that light transmittance through the specimens decreased significantly from baseline for all cleaning methods at 6 months. Flexural modulus of the specimens decreased significantly for all cleaning methods except Invisalign crystals and Retainer Brite (P &gt; .05). The Listerine group demonstrated the worst light transmittance change while H2O2 demonstrated the greatest change in flexural modulus of the specimens compared with other cleaning methods; however, no qualitative difference was observed using SEM analysis.

Conclusions:
The results suggest that different cleaning methods affect long-term physical properties of the ACE retainer material. At the present time, none of these cleaning methods is ideal for copolyester retainer material.
Orthodontic management of a dental anomaly pattern (DAP) including mandibular canine transmigration: A case report: A challenging treatment but worth it!
Authors: Northway William 
Published: August 2018

ABSTRACT
Orthodontic technology has advanced to the point where management of cases with multiple dental anomalies should be within an orthodontist's daily armamentarium. A patient with bilateral agenesis of lower second premolars, delayed development, and transmigration of a mandibular canine was treated with the aid of hemisection, indirect/closed exposure, application of continuous force, targeted delivery, and strict attention to keeping the roots as much in bone as possible. This was accomplished without implants or flattening the facial profile, yet with excellent periodontal status and a fully functioning occlusion.

Published: August 2018

ABSTRACT

Objective:
To compare the flexural properties of rectangular nickel-titanium (Ni-Ti) orthodontic wires in occlusoapical and faciolingual orientations using a standardized test method.

Materials and Methods:
Twenty-two rectangular Ni-Ti wire groups were tested in occlusoapical (ribbon) orientation: eight conventional Ni-Ti products, five superelastic Ni-Ti products, and nine thermal Ni-Ti products (n = 10 per group). Six products of thermal Ni-Ti wire were tested in faciolingual (edgewise) orientation. A three-point bending test was performed to measure deactivation force at 3.0-, 2.0-, 1.0-, and 0.5-mm deflections of each rectangular wire at 37.0 ± 0.5°C. Analysis of variance and post hoc Student-Newman-Keuls tests were used to compare the mean values of the different groups (α = .05).

Results:
The ranges of deactivation forces varied greatly with different kinds, sizes, products, and deflections of Ni-Ti wires. One product of conventional and superelastic Ni-Ti wires had steeper force-deflection curves. Four products had similarly shaped flat force-deflection curves, whereas the sixth product had a moderately steep force-deflection curve. Thermal Ni-Ti wires had smaller deactivation forces ranging from 0.773 N (78.8 g) to 2.475 N (252.4 g) between deflections of 1.0 and 0.5 mm, whereas wider ranges of force from 3.371 N (343.7 g) to 9.343 N (952.7 g) were predominantly found among conventional Ni-Ti wires between deflections of 3.0 and 2.0 mm.

Conclusions:
Clinicians should critically select archwires for use in the occlusoapical orientation not only based on Ni-Ti wire type, size (0.022 × 0.016-in or 0.025 × 0.017-in), and product but also with deactivation deflections from 0.5 and 1.0 mm to obtain light forces in the occlusoapical orientation.

Published: August 2018

ABSTRACT

Objectives:
To compare the effects of different etching techniques, 12–, 24–bladed tungsten carbide burs, and polishing discs on tooth color changes during orthodontic treatment.

Materials and Methods:
59 individuals (mean age: 15.20 ± 1.59 years) were divided into four groups: 37% phosphoric acid and adhesive primer was used in Groups I and II whereas self–etch primer was used in Groups III and IV for enamel preparation. After orthodontic treatment, residual adhesives were cleaned with 12–bladed tungsten carbide burs in Groups I and III, while 24–bladed tungsten carbide burs were used in Groups II and IV. All teeth were polished with medium and fine Sof–Lex XT discs (3M ESPE, St Paul, Minnesota). Color measurements were taken from upper incisors and canines at pretreatment (T0), after cleaning with tungsten carbide burs (T1) and polishing with discs (T2). Wilcoxon test was used for evaluation of L*, a*, b* changes and Kruskal–Wallis for intergroup comparison of color changes.

Results:
L*, a*, b* values, except a* at Groups I, II, IV, and b* at Group III, changed significantly (P &lt; .05). Groups III and IV showed significantly different color alterations from T0 to T1 (P &lt; .05). After polishing, tooth color alterations were not significantly different among the groups.

Conclusions:
In self–etch bonding groups, a 12–bladed tungsten carbide bur caused less color change than the 24–bladed tungsten carbide bur. Orthodontic treatment resulted with visible and clinically unacceptable tooth color alterations regardless of the enamel preparation and clean–up techniques. Polishing reduced the effect of tungsten carbide burs, but did not affect the total influence of orthodontic treatment on the tooth color.

Published: August 2018

ABSTRACT

Objectives:
To assess patient compliance and treatment efficacy of preventive expansion treatment with removable Planas functional appliances using an integrated microsensor.

Materials and Methods:
Wear time (WT) and behavior of 69 patients undergoing treatment with Planas functional appliances were assessed and analysed using TheraMon microsensors (Gschladt, Hargelsberg, Austria). Patients were followed up for a period of 9 months, and visits were made every 3 months to download WT data from the microsensor and to assess wearing behavior. From individual WT graphs,10 parameters were derived to characterize compliance for each patient. Treatment efficacy was measured by eight parameters determining the level of expansion after 9 months of treatment.

Results:
Patients wore their device on average 15.8 ± 5.2 h/d. WT was unrelated to age and gender, but it was positively influenced by patient habits when keeping appliances during eating, sports, care and handling. Treatment efficacy in terms of intercanine and intermolar expansion was 4.4 ± 1.9 mm and 4.6 ± 2.0 mm for the maxilla, and 5.3 ± 2.0 mm and 4.7 ± 2.3 mm for the mandible, respectively. Efficacy was negatively affected by poor compliance (WT &lt; 9 h/d) and by high variability of within-subject WT recordings.

Conclusions:
Perfect compliance is not necessary to achieve treatment success, but patients should exhibit sufficient wear time to allow maxillary expansion to occur. The TheraMon microsensor offers a new perspective and aid to individualize treatment prescriptions.

Adaptation of Runco Ideational Behavior Scale in Latvia
Authors: Kālis Emīls , Roķe Līga 
Published: August 2018

ABSTRACT

Runco Ideational Behavior Scale (RIBS) was developed as an alternative instrument to measure
creativity in contrast with divergent thinking tests which have only moderate predictive validity.
Measure of RIBS is based on the assumption that ideas are the products of original, divergent,
and creative thinking behaviour which one can observe and report about his/herself. The aim
of the study was to adapt RIBS in Latvia. For the estimation of psychometric properties and
constructing validity with confirmatory factor analysis (CFA) two samples were involved -
initial sample (N=107) and comparison sample (N=130). After evaluating the Latvian version
of RIBS, two issues were identified: the first pertains to reversed items which have no sufficient
shared variance with the total scale while the second issue points to serious problems of model fit
challenging one factor solution of ideational behaviour.

The possible reasons of these problems
are discussed and further steps for RIBS development are proposed, including a change of
response scale in order to test the effect of reversed items, establishing the validity with other
instruments and investigating the appropriate number of factors to reveal more valid structure
of ideational behaviour.
Similar to the original RIBS the adapted version also has low factorial validity and thus is
temporarily recommended only for studies with purpose to develop this instrument.

Published: August 2018

<p>In the present paper, we study the linear optical absorption power in triangular quantum wells (QW), subjected to a laser field when electrons are scattered with longitudinal optical phonons (LO phonons). The analytic expressions are obtained for optical absorption power via electron-LO phonon scattering . The linear optically detected electrophonon resonance (ODEPR) effect in a specific GaAs/AlAs quantum well with triangular potential is investigated. Conditions for the ODEPR are determined based on the energy conservation law. From the curves expressing the dependence of the absorption power on photon energy we find the ODEPR-linewidths as profiles of the curves. Computational results show that the ODEPR-linewidths increase with temperature and decrease with electric field.</p>
