Published: September 2023

OBJECTIVES:
The purpose of the study is as follows:

To evaluate the dental and skeletal changes of the AdvanSync 2 appliance.To evaluate the soft tissue changes of the AdvanSync 2 appliance using photometric analysis.

METHODS:
The sample size consisted of 15 patients who reported to the Department of Orthodontics, seeking fixed orthodontic treatment. The effects of the AdvanSync 2 appliance were measured at two intervals.

RESULTS:
After the nine months, P values were observed to be less than 0.5, therefore statistically significant for parameters such as Sella-Nasion-Point A (SNA), Condylion-Point A (CO-A), University of Witwatersrand, Condylion-Gnathion (C0-Gn), point A-Nasion-Point B (ANB), Upper incisor-Point A (UI-A) (degree), LI-B (mm), Lower lip to Esthetic plane (LL-E plane), nasolabial angle, mentolabial angle, facial angle, and L lip to the chin. P values were however observed to be greater than 0.5, therefore statistically insignificant for parameters such as sella-Nasion-Point B (SNB), Condylion –gonion (C0-Go), UI A (mm), LI B (mm), UL-EPL, H LINE, Frankfurt mandibular plane (FMA), nose tip angle, nasofrontal angle, nasomental angle, upper lip angle, and U lip to the chin.

CONCLUSIONS:
AdvanSync 2 appliance brought about a change in Class II malocclusions through Co-Gn, Co-Go, ANB, FMA, UI-A (degree), UI A (linear) LI B (linear), Upper lip to Esthetic plane, LL-E plane, Holdaway LINE, nose tip angle, nasolabial angle, mentolabial angle, nasofrontal angle, nasomental angle, facial angle, upper lip angle, U lip to chin, L lip to the chin after nine months of appliance delivery.

MAIN POINTS:

AdvanSync 2 normalized class II by an increase in the length and body of the mandible.AdvanSync 2 has a restraining effect on the growth of the maxilla.AdvanSync 2 brings about positive soft tissue changes.The major disadvantage is the proclination of the lower incisors.
MH-SETUP, combining Kesling wax-setup with indirect bonding and custom-made brackets for labial/lingual techniques to eliminate the finishing phase
Authors: Elkolaly Mohamed A. , Hasan Hasan Sabah 
Published: September 2023

OBJECTIVE:
A novel technique, named the MH setup (MH is an abbreviation for the author's name), was developed to provide an accurate yet simplified method to produce custom-made brackets without bonding errors. This setup aimed to simplify the treatment and eliminate the finishing phase, so that the orthodontist was able to provide better care with less time and lower costs.

MATERIALS AND METHODS:
The setup was performed in two major steps: direct bonding on the cast followed by cutting and setting the teeth into precise positions using brackets. The first set of brackets, bonded directly onto casts, oriented the teeth by setting them ideally into wax rims with full control over first-, second-, and third-order bends. The fully engaged archwire used allowed for precise control over the arch symmetry and form. Setting teeth in wax allowed the clinician to refine the occlusion and correct any minor errors that arose during the initial bonding. The second set of brackets, mounted on the fully engaged archwire, featured custom-made composite bases. The transfer tray combined the benefits of its soft inner and hard outer layers, providing control over bonding and later ease of peeling from the brackets.

RESULTS:
The patient was satisfied with a full bonding procedure lasting 15 min that remained simple without unnecessary stress. The clinician was confident that the procedure allowed the precise positioning of brackets and simple bonding for all teeth in the arch, combined with the elimination of the finishing phase.

CONCLUSION:
The MH technique offered a simple, precise, and inexpensive improvement to the Kesling wax setup. The process allowed for precise bonding without errors or expensive armamentarium. The brackets were transformed into custom-made prescriptions and could be used with labial or lingual techniques. The method allowed for teeth addition, trimming, or overcorrection according to the clinician's preferences. The MH setup facilitated visualization of the treatment objectives with precise locations and the opportunity to revise the treatment plan or to discuss further options with the patient.

Published: September 2023

OBJECTIVE:
To determine the prevalence of dilaceration in a sample of patients presenting for initial orthodontic care.

METHODS:
Examining radiographs from a random sample of orthopantomogram images was used to acquire the data. In all, 2,801 dental records were evaluated at Oman Dental College (ODC), Oman. A dental X-ray processing software was utilized to view the images. A tooth was classified as having a mesial/distal dilaceration if its long axis exhibited an angle of 90 degrees or greater. Dilacerated roots in the buccal/lingual direction were diagnosed by observing the appearance of a spherical opaque area with a dark shadow in its central region, projected by the apical foramen, which gave the root canal a “bull's-eye” appearance.

RESULTS:
Dilacerations were found in 17.32% of the records examined. The maxillary second molars (22.71%) were the most commonly affected, followed by the mandibular third molars and mandibular lateral incisors (21.90% and 17.23%, respectively). The central incisors and canines were the least affected, with dilaceration affecting less than 0.2% of the teeth. The mandible was found to have more dilacerations than the maxilla (53.78% and 46.22%, respectively). 61.03% of dilacerations occurred in molars, 43.12% of which occurred in third molars.

CONCLUSION:
Dilaceration is a notable dental anomaly that can affect any tooth, with some teeth being more affected than others. Dilaceration in maxillary second molars and mandibular lateral incisors is more common in the population of this study than in other populations reported in the literature. Recognizing the condition will allow for more effective orthodontic treatment.

Published: September 2023

OBJECTIVE:
This study aimed to evaluate the clinical and histological administration of magnesium oxide (MgO) supplementation on orthodontic relapse and bone remodeling.

MATERIALS AND METHODS:
Twenty male albino rabbits were classified into four groups (five animals for each as two control (positive and negative), plus two experimental (low dose 40 mg/kg) and (high dose 80 mg/kg)/b.w. daily). An orthodontic force was applied (40 gm) to the lower incisors using modified orthodontic appliance adapted on the lower central incisors. During the period of retention, MgO was given orally. Relapse was estimated after appliance removal. A digital Calliper was used to compete the space between incisors' mesial tips of rabbits at six successive time points (0, 3, 7, 10, 15, and 21 days). Histologically, osteoblast, osteoclast, and osteocyte account were assessed. Data analyses were performed by SPSS using ANOVA and Tukay HSD (P ≤ 0.05) for statistically significant differences between groups.

RESULTS:
The high dose group had a lower relapse rate than the low dose and control groups. Histologically, the high dose group had more osteoblasts and osteocytes than low dose and control groups. While osteoclasts were significantly lower than the control group in low and high dose groups.

CONCLUSIONS:
MgO supplementation during an orthodontic retention phase, particularly at a level of high dose, clinically decreased orthodontic relapse in a rabbit model. Histologically, MgO has a significant effect on alveolar bone after the orthodontic retention period.

Published: September 2023

OBJECTIVES:
To evaluate and compare the shear bond strength of stainless-steel brackets using three different light curing units

MATERIAL AND METHODS:
Using three LED curing units (3M ESPE Elipar, Ivoclar bluephase, and Woodpecker I LED light cure), 120 precoated metal brackets (Gemini series, 3M Unitek) were cured. The shear bond strength was recorded using a universal testing machine.

RESULT:
The shear strength of the bracket in different light-curing systems was examined with ANOVA test. The mean shear strength of group A, group B, and group C were 16.03 ± 14.30 MPA, 16.86 ± 11.89 MPA, and 20.51 ± 19.40, respectively. The result of the analysis shows that there is a major difference in shear bond strength of these three different light-curing systems with F value = 3.94 and P value 0.04

CONCLUSION:
We used three LED light-curing units with different intensities and manufacturing companies. The result showed that woodpecker I LED light had significantly highest mean SBS than the other two (Elipar LED curing light and 3M ESPE, Ivoclar bluephase).

IntroductionThe aim of the study was to examine the association between frailty and osteoarthritis.Material and methodsWe conducted a cross-sectional study in the National Health and Nutrition Examination Survey, while logistic regression was used to explore the association of the two. Mendelian randomization (MR) study was used to explore the causal relationship between the two.ResultsIn the cross-sectional study, logistic regression analysis showed that odds ratio (OR) (95% CI) value was 1.07 (1.05, 1.08). In the MR study, the inverse-variance weighting (IVW) results showed OR (95% CI) value of 1.69 (1.01–2.83).ConclusionsThere is both a correlation and a causal relationship between frailty and osteoarthritis, and frailty may be a potentially better response than age to osteoarthritis.
Coastal earthquake-induced landslide susceptibility during the 2016 Mw 7.8 Kaikōura earthquake, New Zealand
Authors: Bloom Colin K. , Singeisen Corinne , Stahl Timothy , Howell Andrew , Massey Chris , Mason Dougal 
Published: September 2023

Abstract. Coastal hillslopes often host higher concentrations of
earthquake-induced landslides than those further inland, but few studies
have investigated the reasons for this occurrence. As a result, it is
unclear if regional earthquake-induced landslide susceptibility models
trained primarily on inland hillslopes are effective predictors of coastal
susceptibility. The 2016 Mw 7.8 Kaikōura earthquake on the
northeastern South Island of New Zealand resulted in ca. 1600 landslides > 50 m2 on slopes > 15∘ within 1 km of
the coast, contributing to an order of magnitude greater landslide source
area density than inland hillslopes within 1 to 3 km of the coast. In this
study, logistic regression modelling is used to investigate how landslide
susceptibility differs between coastal and inland hillslopes and to determine
the factors that drive the distribution of coastal landslides initiated by
the 2016 Kaikōura earthquake. Strong model performance (area under the
receiver operator characteristic curve or AUC of ca. 0.80 to 0.92) was
observed across eight models, which adopt four simplified geology types. The
same landslide susceptibility factors, primarily geology, steep slopes, and
ground motion, are strong model predictors for both inland and coastal
landslide susceptibility in the Kaikōura region. In three geology types
(which account for more than 90 % of landslide source areas), a 0.03 or
less drop in model AUC is observed when predicting coastal landslides using
inland-trained models. This suggests little difference between the features
driving inland and coastal landslide susceptibility in the Kaikōura
region. Geology is similarly distributed between inland and coastal
hillslopes, and peak
ground acceleration (PGA) is generally lower in coastal hillslopes. Slope angle,
however, is significantly higher in coastal hillslopes and provides the best
explanation for the high density of coastal landslides during the 2016
Kaikōura earthquake. Existing regional earthquake-induced landslide
susceptibility models trained on inland hillslopes using common predictive
features are likely to capture this signal without additional predictive
variables. Interestingly, in the Kaikōura region, most coastal
hillslopes are isolated from the ocean by uplifted shore platforms. Enhanced
coastal landslide susceptibility from this event appears to be a legacy
effect of past erosion from wave action, which preferentially steepened
these coastal hillslopes.

Abstract. Theoretical and numerical work has shown that under certain circumstances grounding lines of marine-type ice sheets can enter phases of irreversible advance and retreat driven by the marine ice sheet instability (MISI). Instances of such irreversible retreat have been found in several simulations of the Antarctic Ice Sheet. However, it has not been assessed whether the Antarctic grounding lines are already undergoing MISI in their current position. Here, we conduct a systematic numerical stability analysis using three state-of-the-art ice sheet models: Úa, Elmer/Ice, and the Parallel Ice Sheet Model (PISM). For the first two models, we construct steady-state initial configurations whereby the simulated grounding lines remain at the observed present-day positions through time. The third model, PISM, uses a spin-up procedure and historical forcing such that its transient state is close to the observed one. To assess the stability of these simulated states, we apply short-term perturbations to submarine melting. Our results show that the grounding lines around Antarctica migrate slightly away from their initial position while the perturbation is applied, and they revert once the perturbation is removed. This indicates that present-day retreat of Antarctic grounding lines is not yet irreversible or self-sustained. However, our accompanying paper (Part 2, Reese et al., 2023a) shows that if the grounding lines retreated further inland, under present-day climate forcing, it may lead to the eventual irreversible collapse of some marine regions of West Antarctica.

Authors: Liu Jialin 
Published: September 2023

The English Curriculum Standards for Compulsory Education (2022 Edition) (from now on referred to as "the new standards") mentions students' intercultural communication many times in the curriculum objectives. Under the requirements of the new standards, teachers should pay attention to cultivating students' intercultural communication awareness and ability. In the era of economic globalization, diversified modes of thinking, and information networking, the practice and exploration of cultural self-confidence have become vital prerequisites for cultivating students' cross-cultural communicative competence. Therefore, this paper explores the enhancement and development of junior high school students' intercultural communicative competence from the aspects of the meaning of intercultural communicative competence, the problems and challenges encountered in cultivating students' intercultural communication, the current situation of the cultivation of junior high school students' intercultural communicative competence, the necessity of improving junior high school students' intercultural communicative competence, the principles of the cultivation of junior high school students' intercultural communicative competence, as well as the strategies of the cultivation of junior high school students' intercultural communicative competence.

Published: September 2023

Background: Tonsillitis is a common infectious disease contributing to significant social-economic impact worldwide. Like other infectious diseases, the determination of the pathogenic agents is important in antibiotic selection for the medical treatment of tonsillitis. Data on bacteriology of tonsillitis in Tanzania is scarce. The aim of this study was thus to determine the prevalence and bacteriology of tonsillitis in one of the largest tertiary hospital in Tanzania.
Methods: Descriptive cross-sectional study was conducted involving 485 patients at Muhimbili National Hospital, from June to December 2016. Data was collected using specially designed questionnaires. Laboratory isolation of bacterial pathogens implicated in tonsillitis followed by consequent antimicrobial susceptibility testing was doneat the Country's largest laboratory. Gathered data was then analyzed using the SPSS program version 20.
Results: A total of 485 patients were recruited in the study, where majority were females (55.7%) and the mean age was found to be 27.7 years. Out of 485 patients 100(20.6%) had tonsillitis. Male preponderance was found (51%). The most affected age group was 1-10years (42.6%). Nearly 25% of patients had family history of tonsillitis with siblings being commonly affected. The isolated bacteria were Coagulase negative staphylococcus 41.7%, S. pyogenes 40%, Bacillus species 8.3%,K.pneumoniae 5.8%, E.Coli 2.5% and P.aeruginosa 1.7%. S.pyogeneswas susceptible to Ceftriaxone 95.7%; Azithromycin 93.6%; Doxycline 91.5%; Clindamycin 87.2%; Ampicillin 80.9%; Erythromycin 74.5%; Amoxiclav 59.6% and resistant to penicillin G(38.3%).
Conclusion: Tonsillitis was found to be prevalent in our setting with young individuals being most commonly affected. Male preponderance was found in this study and family history of tonsillitis was depicted in nearly 25% of patients. Majority had recurrent tonsillitis and S. pyogenes was found to be the commonest isolated pathogenic bacterium and was susceptible to most of the drugs available in our setting though it was found to be resistant to penicillin G.
Progress in Legal Methodology – A Methodological Assessment of Six PhD Theses
Authors: Taekema Sanne , van Klink Bart 
Published: September 2023

Progress in Legal Methodology – A Methodological Assessment of Six PhD Theses. Special Issue Progress in Legal Scholarship, Marnix Snel, Sanne Taekema & Gijs van Dijck (eds.)
In this article, the question is raised to what extent the methodology debate in legal scholarship has improved the practice by PhD researchers of justifying their methodology. Over the past twenty years, there has been much more consideration and discussion of legal methods, especially in Dutch academia. Taking this Dutch debate as a starting point, Taekema and Van Klink argue that it has led to a normative framework with which the methodology of legal research can be assessed. Formulating a set of topics and questions that form the core of this framework, they apply it to a set of six fairly recent PhD dissertations. Building on these cases, they observe that some progress is made from a methodological point of view, compared with the situation described by Tijssen in his PhD thesis from 2006. Taekema and Van Klink conclude, however, that the methodology debate appears not to have led to a significantly better practice of methodological justification, at least not yet on all assessment criteria. The normative framework of a dissertation, for instance, still deserves attention.
