Published: October 2024

Abstract

Purpose
This study’s goal was to assess the impact of the coronavirus disease 2019 (COVID-19) outbreak on parent’s knowledge, attitude, and children’s anxiety during dental treatment.

Patients and methods
A structured questionnaire was applied to a sample of 400 parents of children aged from 8 to 15 years and from different socioeconomic backgrounds. The children’s dental anxiety level was assessed using the Facial image scale. The accompanied parent’s and dentist’s dental anxiety level was also evaluated using a Likert scale, 1–6.

Results
In total, 71.5% of parents answered that their children could be infected with COVID-19 during dental treatments and that they were concerned about their children receiving such treatment due to the outbreak. When asked about the transmission of COVID-19, 90% of participants believed it was due to aerosol-generating procedures during dental treatment.

Conclusion
The COVID-19 pandemic has had an impact on parental attitudes about dental care and oral health management.

Authors: El Shishtawy Hesham M. , El-Shorbagy Zeinab A. , Abdelaal Zainab M. 
Published: October 2024

Abstract

Aim
To assess retention and wear of two different bar materials (cobalt chromium and poly ether-ether ketone) used in implant-retained mandibular overdenture subjected to chewing simulation Robota during 1 year of functional simulation.

Patients and methods
This study is a comparative laboratory study which was carried out on 14 models of implant-retained mandibular overdenture, for each model two implants were inserted. The 14 models were divided equally into two equal groups: group A (overdenture constructed over two implant analogs with bar attachment and clip made from cobalt chromium material), and group B (overdenture constructed over two implant analogs with bar attachment and clip made from poly ether-ether ketone material). Drilling of the models was done using milling machine and each model received two implant analogs inserted 11 mm from midline at canine region. The overdentures were constructed in the usual manners and the teeth were set in lingualized occlusion. The mandibular overdentures were subjected to 150 000 chewing cycles using Robota chewing simulator and 1080 insertion-removal cycles. Retention of the samples was measured by the universal testing machine and wear observed under USB digital microscope both of which were done at the beginning of the study and after 3, 6, 9, and 12 months.

Results
The retention force for group A decreased significantly from baseline 43.43 ± 5.25 to 35.56 ± 8.30 after 3 months of cyclic loading, with similar reductions after 6, 9, and 12 months. Group B also showed reductions from baseline 26.75 ± 2.32 to 21.29 ± 6.74 after 3 months, and similar patterns over time. Group A had no statistically significant wear changes after cyclic loading, with a baseline mean of 0.2904 ± 0.0008, changing to 0.2913 ± 0.0008 after 3 months, while group B showed similar nonsignificant changes. There were no statistically significant differences in wear between both groups at any time point.

Conclusion
Retentive forces decrease with increasing cyclic loading. However, both materials displayed acceptable retentive values. Wear values were nonsignificant between two studied groups.

Authors: Badr Ahmed M. , Shoukheba Malak Y.M. , El-Kholey Sohier E. 
Published: October 2024

Abstract

Aim
The use of natural remedies as local drug delivery has grown recently since they are generally safe and have shown promising outcomes in the management of periodontitis. The purpose of this study was to evaluate the effectiveness of spirulina gel and probiotics as supplements for scaling and root planing (SRP).

Patients and methods
Thirty individuals with periodontitis (stage II, grade B) were divided into three groups at random: group I (GI) received a subgingival application of probiotic (Lactobacillus reuteri) suspension after SRP. Group II (GII) had SRP, then spirulina gel was applied. Group III (GIII) was used as a control that received SRP and placebo gel using a blunt syringe at baseline, 1, 2, and 4 weeks. Gingival index (GI), probing pocket depth, clinical attachment level (CAL), and gingival crevicular fluid nitric oxide level were assessed at baseline, 3, and 6 months.

Results
Compared to the baseline value, the three treatments led to a statistically significant decrease in GI, probing pocket depth, and clinical attachment level gain after 3 and 6 months (P < 0.05). Comparing the groups to each other’s, there were significant differences between them, whereas both GI and GII showed statistically significant differences when compared to GIII (the control group). All treatment modalities resulted in a statistically significant reduction in the gingival crevicular fluid level of NO, but group II showed the best effect on the inhibition of the nitric oxide level.

Conclusion
Local application of probiotics and spirulina is safe and effective as adjunctive treatment to SRP in the treatment of stage II, grade B periodontitis.
Comparative evaluation of shear bond strength of orthodontic brackets bonded with two self-etching adhesive systems: an in vitro study
Authors: Eissa Osama , Morad Mohamed S. 
Published: October 2024

Abstract

Objective
To evaluate and compare the shear bond strength (SBS of the new Optibond eXTRa Universal and Adper Prompt L-Pop self-etch adhesive systems using an in vitro experimental design.

Patients and methods
The sample included 40 freshly extracted human maxillary first premolars collected from orthodontic patients, adhering to ethical guidelines. The teeth were randomly assigned to two groups, one treated with Optibond eXTRa Universal self-etch adhesive and the other with Adper Prompt L-Pop. Stainless-steel brackets were then bonded to the teeth using BracePaste orthodontic adhesive composite resin. After storage and thermocycling, SBS was measured using a universal testing machine, and adhesive remnant index (ARI) scores were assessed under a digital microscope. Statistical analyses were performed, including the Shapiro–Wilk method, Student’s t-test for SBS, and χ
2 test for ARI scores.

Results
The mean SBS showed no significant difference between both groups (P = 0.076). However, the distribution of ARI scores exhibited a highly significant difference between the two groups (P < 0.001).

Conclusion
While both adhesives exhibited similar bond strengths, variations in adhesive residue patterns highlight the importance of considering adhesive performance in orthodontic applications such as ease of cleanup and potential impact on enamel health.

Authors: Elsayed Mohamed A.E. , El-dessouky Radwa A. , Shakal Mahmoud A.-A. 
Published: October 2024

Abstract

Background
Poly ether ether ketone (PEEK) crowns and abutments can be used to fabricate esthetic and stable implant supported single tooth abutment and short implants can be used to avoid problems and contraindication of standard implants. The aim of this work was to evaluate fracture strength of PEEK abutment over short implant after fatigue.

Methods
This experimental laboratory study was carried out on 40 implants. Implants were categorized into two equal groups: group I: short implants which subdivided into two equal groups (group IA: PEEK abutments and group IB: Titanium abutments), and group II: standard implants which subdivided into two equal groups (group IIA: PEEK abutments and group IIB: Titanium abutments). Zirconia crowns were fabricated and cemented to abutments with resin cement and artificially aged through dynamic loading by chewing simulator to stimulate 3 months clinically.

Results
All test specimens survived the artificial aging process using simulated oral conditions. Group (GIIA) show the highest fracture resistance with the mean value (1526.81 ± 2.91) followed by group (GIA) (1265.32 ± 1.06) then group (GIIB) (1095.44 ± 0.84) and finally group (GIB) (1086.99 ± 1.52), there was highly significance difference between short and standard implants. The effect of abutment material there was also highly significant difference between PEEK and titanium Abutments, group (GIIA) under electron microscope showed unfavorable fracture while all other groups showed favorable fracture only.

Conclusions
The highest fracture strength was found in zirconia crowns cemented to PEEK abutment over standard implant, The lowest fracture strength was found in zirconia crowns cemented to titanium abutment over short implant and Standard implants have favorable stress distribution than short implants under loading.

Authors: Gamil Khaled H. , Saad Khaled A. , Bedar Rafic R. , Elshrief Ahmed M. 
Published: October 2024

Abstract

Background
Posterior maxillary implant rehabilitation is a critical procedure because of the diminished bone quality and quantity, especially in severe atrophic posterior maxilla which affect the stability of the implant and raises the demand of the sinus floor elevation, bone augmentation and ensuring implant stability in order for the implant to succeed. Transalveolar sinus lifting is a valuable technique in reaching and augmenting the floor of the sinus without penetrating the sinus membrane or causing sinusitis and to avoid numerous surgical interventions.

Patients and methods
This is a prospective, interventional clinical study that was carried out on 10 adult patients who had missed posterior maxillary teeth and wanted to restore it, with less than 5 mm residual bone height and greater than 7 mm bone width which treated with transalveolar sinus lifting using corticocancellous bone block containing the implant from the chin bone. All patients are followed-up clinically and radiographically by cone beam computed tomography.

Results
Our technique was performed successfully in all cases without any signs of infection or sinusitis and all implants inserted were clinically stable after 6 months with radiographic significant increase in the bone height and density around the implants.

Conclusion
Transalveolar sinus lifting using press-fitted corticocancellous bone block containing implant from chin bone was found to be highly effective technique for posterior maxillary rehabilitation in severe atrophic posterior maxilla.

Authors: Ушаков В.Н. 
Published: October 2024

Четкое понимание содержания того или иного правового ме­ханизма позволяет обеспечить высокую эффективность реализации заклю­ченных в нем правовых возможностей. Неоднозначное, двоякое толкование нормы права влечет за собой неполноценность или же вовсе отсутствие не­обходимого уровня ее реализации. В статье анализируется терминологиче­ское содержание права на благоприятную окружающую среду. Рассмотрены ключевые составляющие данного права. Определены некоторые особенно­сти, сходства и различия терминов «окружающая среда», «природная сре­да», «благоприятная окружающая среда», а также иных терминов, связанных с исследуемой тематикой. Отмечена целесообразность законотворческих инициатив по развитию терминологии благоприятной окружающей среды. Представляется возможным расширение круга толкования термина благо­приятности, что в дальнейшем позволит повысить степень эффективности реализации исследуемого права.
A clear understanding of the content of a particular legal mechanism makes it possible to ensure high efficiency in the implementation of the legal possibilities contained therein. An ambiguous, twofold interpretation of a rule of law entails inferiority or even absence of the necessary level of its implementation. The article analyzes the terminological content of the right to a favorable environment. Key components of this right are considered. The author identifies some its features, as well as similarities and differences of terms "environment, "natural environment", "favorable environment", as well as other terms related to the subject under study. The expediency of legislative initiatives to develop the terminology of a favorable environment is noted. It seems possible to widen interpretation of the term of favorability, which in the future will enhance effectiveness of the implementation of the studied right.

Local Solutions for Local Problems
Authors: Yates Russell 
Published: October 2024

Teacher shortage in rural localities is a long-standing issue in New Zealand. This paper reports on an attempt to reduce the impact of shortages by redesigning the way preservice teacher education was delivered. Called the Mixed Media Programme (MMP), this is a primary (elementary) teacher education programme that was established in 1997 in New Zealand by the University of Waikato. It was initially introduced to rural areas of the North Island of New Zealand. It continues now as a viable and accessible flexible option for teacher education and is a significant means of ensuring better teacher supply in numerous rural areas. The programme uses a combination of face-to-face teaching; school based learning activities and electronic communication. There is an annual intake of about 60 student teachers, most of who study at home in their local area. Now in its tenth year, the programme has produced more than 400 graduates, many of whom are still teaching in schools throughout New Zealand. This paper reports on a small-scale study, which sought to examine the way that student teachers, teachers and school principals from two communities perceive the programme and its effects on these communities. School principals, teachers, graduates and current student teachers were asked about the way that the programme has enabled people from local ommunities to firstly study to become teachers in these communities and then to teach in them. Their views show that student teachers have found this approach to teacher education very beneficial to local communities for a number of reasons, including stable staffing for schools, commitment to teacher education programmes, confidence about the quality of the raduates they employed. The student teachers reported that they were able to become teachers without having to leave their local communities, were exposed to university education as mature student teachers and that their study has had a range of effects on them and their families. It can be concluded from the evidence that the Mixed Media Programme has had important positive effects upon the two small communities of the study, at individual, school and wider community level.
Using Web2.0 Applications to Close the Digital Divide in Western Australia
Authors: Trindad Sue , Broadley Tania 
Published: October 2024

The research reported in this paper documents the use of Web2.0 applications with six Western Australian schools that are considered to be regional and/or remote. With a population of two million people within an area of 2,525,500 square kilometres Western Australia has a number of towns that are classified as regional and remote. Each of the three education systems have set up telecommunications networks to improve learning opportunities for students and administrative services for staff through a virtual private network (VPN) with access from anywhere, anytime and ultimately reduce the feeling of professional and social dislocation experienced by many teachers and students in the isolated communities. By using Web2.0 applications including video conferencing there are enormous opportunities to close the digital divide within the broad directives of the Networking the Nation plan. The Networking the Nation plan aims to connect all Australians regardless of where they are hence closing the digital divide between city and regional living. Email and Internet facilities have greatly improved in rural, regional and remote areas supporting every day school use of the Internet. This study highlights the possibilities and issues for advanced telecommunications usage of Web2.0 applications discussing the research undertaken with these schools.
