Authors: Al-Alzawi Sarab Mahdi , Al-Jibouri Mahmoud Najim , Rasheed Anaam Majeed , Al-Bayati Sinan Midhat
Published: February 2023

A new ligand of 1,2,4-triazole derivative was produced by cyclization of sodium dithiocarbamate derivative of ethyl 4-ethoxy-3-nitrobenzoate with carbon disulfide in an alkaline medium. The new ligand, entitled name: L: 4-amino-5-(3-ethoxy-5-nitrophenyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione, was fully characterized depending on HPLC-MS, FTIR, 1H-NMR and 13C-NMR spectroscopies. In addition, the elemental microanalysis was carried out to confirm the skeletal structure of the ligand L. A library of complexes with Ni(II), Zn(II), Pd(II), and Pt(IV) metal ions was prepared by coordination with the ligand. These complexes were characterized by using FTIR, UV-Ѵis, 1H-NMR, 13C-NMR, spectrophotometric techniques, elemental analysis C.H.N.S, and FAAS. The physicochemical properties of these complexes were determined at 25 °C, such as melting point, magnetic susceptibility and molar conductivity. The microbial study confirmed that the novel ligand and its complexes have the potential to be applied as antimicrobial agents.

Oily sludge is a solid emulsified waste created by the petroleum industry. Solid particles, crude oil, and water comprise most of their composition. Because it contains high concentrations of cycloalkanes, benzene series, polycyclic aromatic hydrocarbons, and other harmful and hazardous substances, it poses a severe risk to human health and the environment. It must be treated to reduce its toxicity. However, crude oil is a significant component of oily sludge and has a high recycling value. As a result, numerous procedures for extracting crude oil from oily sludge have been developed, including solvent extraction, pyrolysis, centrifugation, ultrasonic treatment, electronic treatment, flotation, supercritical treatment, and combination processes. The primary purpose of this review is to describe the evolution of various recycling technologies and to compare their benefits, drawbacks, and ways of action. This concept is expected to be the cornerstone for future recycling technology development.

Published: February 2023

Aim: To understand academic support structures for Washington state public high school students with concussion during the COVID-19 pandemic. Materials & methods: Prospective, repeated cross-sectional study of 21 schools in 2020 and 2021. Results: About 28% of schools reported not providing any return-to-learn (RTL) accommodations for students with concussion throughout the COVID-19 pandemic. RTL accommodation provision was associated with larger student body size ( β = 0.002) and higher graduation rate ( β = 0.261) but was not associated with presence of RTL school policy. About 38.1% of schools received no guidance on how to provide RTL accommodations during the COVID-19 pandemic, and many reported that students with concussion struggled more. Conclusion: Schools struggled to provide RTL accommodations for students with concussion during the COVID-19 pandemic, highlighting the need for evidence-based guidance and resource allocation to vulnerable schools.

Published: February 2023

Federal funding agencies in the United States (U.S.) continue to work towards implementing their plans to increase public access to funded research and comply with the 2013 Office of Science and Technology memo Increasing Access to the Results of Federally Funded Scientific Research. In this article we report on an analysis of research data sharing policy documents from 17 U.S. federal funding agencies as of February 2021. Our analysis is guided by two questions: 1.) What do the findings suggest about the current state of and trends in U.S. federal funding agency data sharing requirements? 2.) In what ways are universities, institutions, associations, and researchers affected by and responding to these policies? Over the past five years, policy updates were common among these agencies and several themes have been thoroughly developed in that time; however, uncertainty remains around how funded researchers are expected to satisfy these policy requirements.

Published: February 2023

Abstract: Facial Emotion Recognition plays a significant role in interacting with computers which help us in various fields like medical processes, to present content on the basis of human mood, security and other fields. It is challenging because of heterogeneity in human faces, lighting, orientation, poses and noises. This paper aims to improve the accuracy of facial expression recognition. There has been much research done on the fer2013 dataset using CNN (Convolution Neural Network) and their results are quite impressive. In this work we performed CNN on the fer2013 dataset by adding images to improve the accuracy. To our best knowledge, our model achieves the accuracy of 70.23 % on fer2013 dataset after adding images in training and testing parts of disgusted class.

Authors: Karpenko Nikolay I. , Moiseenko Gennady A.
Published: February 2023

The authors review the results of complex theoretical studies of the physico-mechanical and rheological properties of high-strength steel-fiber concrete in comparison with non-reinforced fine-grained high-strength concrete made of self-compacting mixtures under short-term and long-term load exposure. Based on the data of extensive experimental studies, methods of Mathematical description of concrete properties depending on the key factors of influence have been selected and developed. A steel fiber concrete with a minimum content of the selected type of fiber is studied, at which the positive effect of fiber reinforcement begins to manifest itself. The theoretical approach of V.M. Bondarenko to the description of creep measures of steel fiber concrete has been developed. The developed methods can be used to calculate structures made of high-strength steel-fiber concrete using the modern diagram method.
Stability of shallow shells with local changes in strength characteristics
Authors: Kolesnikov Alexander G. , Osadchaya Antonina V.
Published: February 2023

The authors deal with the structures of buildings in the form of shallow shells with some damage. The derivation of equations is given taking into account the geometric nonlinearity of the work of a thin-walled structure. A technique for solving systems of equations using the Bubnov - Galyorkin method is given. The work of the structure with various ways of fixing the edges is simulated. Damage is specified by changing the modulus of elasticity in an arbitrary section of the structure. The influence of the shape and location of the defect on the value of the critical load is investigated. The results of the studies carried out are given in a dimensionless form and illustrated by graphs, which makes it convenient to use them in engineering calculations. Recommendations are given for correcting the shape and thickness of coating structures in the form of shallow shells in order to maintain their bearing capacity in the event of defects. The proposed method can be used to determine and investigate the stress-strain state of structures in the form of shallow shells, taking into account the geometric nonlinearity of work in the presence of defects in them. The constructed graphs of the dependence of the critical load on various parameters make it possible to evaluate the operation of structures, taking into account changes in various factors at various stages of the structure's operation. The use of varying characteristics of the reduction in the modulus of elasticity, which appears because of the occurrence of a defect, shows results that are close to real conditions.

Earnings less risk-free interest charge (ERIC) and stock returns: ERIC’s relative and incremental information content in a European sample
Authors: Griskaite Aurelija , Lueg Rainer
Published: February 2023

This study tests the information content of earnings less risk-free interest charge (ERIC) and analyses its ability to explain fluctuations in market-adjusted stock returns. Following Biddle et al. (1997) study design, we perform relative and incremental information content tests. Relative information content tests reveal that mandatory reporting metrics — such as earnings before extraordinary items (EBEI), cash flow from operations (CFO), and total comprehensive income (TCI) — are more highly associated with stock returns and firm values than ERIC or residual income (RI). A number of sensitivity analyses support our findings. To test incremental information content, we split ERIC into five components. Primary results indicated that components specific to ERIC — changes of net assets, after-tax interest expenses, and capital charge — do not add relative information content. Yet, sensitivity tests suggest that some ERIC components add incremental information, especially when accounting for market expectations. However, these findings are not economically substantial compared to CFO and EBEI. Overall, we conclude that mandatory metrics generally outperform ERIC and residual income. Our unique contribution lies in applying the established methodology of measuring economic value added (EVA’s) relative and incremental information content to ERIC

Published: February 2023

The COVID-19 pandemic posed a significant impediment to experimental
research, leading several researchers to adapt psychophysical data
acquisition. With the development and proliferation of information
technology, paper-based organizational processes have gradually begun to
be replaced by computer-based equivalents. This study describes how we
developed, analyzed data, and validated the temporal bisection task in a
remote data acquisition scenario. We implemented the data acquisition
using the open science software OpenSesame, in conjunction with the
JATOS platform. We described in detail all the steps to use our codes,
which we made available for reuse. We acquired data from 28 participants
using the remote acquisition system and compared them with data obtained
in person (from Penney et al., 2000). Our remote data showed compatible
results with live experiments, suggesting that the modality of data
acquisition (remote or live) does not influence the results.

Published: February 2023

Objective: To assess the clinical performance of the human
papillomavirus (HPV) 16 18/45 genotype assay (AHPV-GT) combined with age
stratification in triaging women with histologic low-grade squamous
intraepithelial lesion/cervical intraepithelial neoplasia grade 1 (LSIL
[CIN1]) preceded by HPV E6/E7 mRNA assay (Aptima HPV, AHPV)
positive/normal or mildly abnormal cytology. Design:
Longitudinal study. Setting: Gynaecological clinic in Huzhou
Maternity & Child Health Care Hospital, China. Population:
Women aged ≥21 years with histologic LSIL (CIN1) preceded by
AHPV-positive/normal or mildly abnormal cytology. Methods:
Women underwent AHPV-GT testing at baseline and were followed at 6-month
intervals for up to 2 years. At each follow-up, women with abnormal
cytology or AHPV positivity were referred for colposcopy and then biopsy
if indicated. Main outcome measures: The 2-year cumulative
incidence rates (CIRs) of CIN3+ stratified by baseline AHPV-GT
genotyping. Results: Of 349 eligible women, 25 women (7.2%)
progressed, 301 (86.2%) regressed, and 23 (6.6%) persisted during the
follow-up. The 2-year CIRs of CIN3+ in AHPV-GT-positive women were both
significantly higher than those in AHPV-GT-negative women overall (8.6%
vs. 1.7%, P = 0.014) and in the ≥25-year-old group (10.9% vs.
1.5%, P = 0.002) but slightly higher in the 21–24-year-old
group ( P > 0.05). Conclusions: AHPV-GT
testing with age stratification is effective for triaging women with
histologic LSIL (CIN1) preceded by AHPV-positive/normal or mildly
abnormal cytology. Immediate treatment is a rational recommendation for
women ≥ 25 years old with histologic LSIL (CIN1) preceded by AHPV-GT
positivity when good surveillance is not assured.

Published: February 2023

In order to explore the stoichiometric characteristics of nitrogen (N)
and phosphorus (P) of Haloxylon ammodendron on the south edge of
Gurbantungut Desert, and to reveal the adaptability of desert plants to
nutrient utilization in barren habitats, this study took the south edge
of Gurbantungut Desert in Xinjiang as a typical area. The contents of N
and P in leaves, stems and roots of H. ammodendron were measured and
analyzed, and the correlation between the ecological stoichiometry of N
and P in organs and soil factors was discussed, as well as the influence
of the samples and organs. The results showed as follows: (1) There were
significant differences in N content, P content and N:P among different
organs of H. ammodendron, and the trend of each index was roughly the
same. The general trend was higher in leaves, followed by stems and
roots. (2) Correlation analysis showed that N content in all organs of
H. ammodendron was positively correlated with soil total nitrogen. P
content in leaves and roots was significantly positively correlated with
soil total P, while P content in stems was significantly negatively
correlated with soil total P. P content in all organs was negatively
correlated with soil N:P. The contents of N, P and N:P in different
organs were negatively correlated with soil pH and electrical
conductivity. (3) General linear model analysis showed that organs had
great influence on N content, P content and N:P of H. ammodendron.
Defining Optimal Health Indicators for Life Expectancy Analysis and Management
Authors: Dugina Tatiana , Arshukova Irina , Narkevich Artem N. , Sadovsky Michael G.
Published: February 2023

In pre-pandemic period (1999‒2019), we analyzed mortality data for the
Krasnoyarsk Territory (Central Siberia, Russia) with population about
2.9 million people. Causes of death affecting life expectancy at birth
(LE) were analyzed based on cause-specific and age-specific indicators.
Based on the cause-elimination life-table analysis, we estimated the
mortality rate and the contribution of a specific cause of death to LE
using an alternative approach (altPGLE) and included the contribution of
a single case of death. In 2019, ischemic heart disease, cerebrovascular
disease, and malignant neoplasms of digestive organs provided the most
significant contribution to LE primarily due to its high mortality rate.
Intentional self-harm, HIV, and tuberculosis provide the most
outstanding contribution of a single case of death to LE since they
affect younger people. Over the period, deaths from cardiovascular
diseases shifted to the elderly groups, but from liver diseases became
ten years ‘younger’. However, circulatory diseases still provide the
most significant impact on LE. Health policymakers should take into
account and improve three leading indicators: mortality rate, the
contribution of all death cases to LE (altPGLE), and the contribution of
a single case of death to LE. The improvement can be achieved by
preventing diseases that affect the younger population (in our case,
intentional self-harm, HIV, tuberculosis, and liver diseases) and
delaying death from diseases that are common in older people
(circulatory system diseases and cancer). It is also important to
identify and govern diseases that get ‘younger’ over time.
End-to-End Deep Learning Framework for Real-Time Inertial Attitude Estimation using 6DoF IMU
Authors: Asgharpoor Arman , Sabour Mohammad Hossein
Published: February 2023

Inertial Measurement Units (IMU) are commonly used in inertial attitude
estimation from engineering to medical sciences. There may be
disturbances and high dynamics in the environment of these applications.
Also, their motion characteristics and patterns also may differ. Many
conventional filters have been proposed to tackle the inertial attitude
estimation problem based on IMU measurements. There is no generalization
over motion and environmental characteristics in these filters. As a
result, the presented conventional filters will face various motion
characteristics and patterns, which will limit filter performance and
need to optimize the filter parameters for each situation. In this
paper, two end-to-end deep-learning models are proposed to solve the
problem of real-time attitude estimation by using inertial sensor
measurements, which are generalized to motion patterns, sampling rates,
and environmental disturbances. The proposed models incorporate
accelerometer and gyroscope readings as inputs, which are collected from
a combination of five public datasets. The models consist of
convolutional neural network (CNN) layers combined with Bi-Directional
Long-Short Term Memory (LSTM) followed by a Fully Forward Neural Network
(FFNN) to estimate the quaternion. To evaluate the validity and
reliability, we have performed an extensive and comprehensive evaluation
over five publicly available datasets, which consist of more than 120
hours and 200 kilometers of IMU measurements. The results show that the
proposed method outperforms the state-of-the-art methods in terms of
accuracy and robustness. Furthermore, it demonstrates that this model
generalizes better than other methods over various motion
characteristics and sensor sampling rates.

Published: February 2023

This paper outlines an experimental investigation into the durability of
large-scale adhesively bonded joints immersed in a 3.5 wt% NaCl
solution for 10 weeks at 50°C. Two aged and one unaged specimen were
subjected to tensile testing up to failure, and three aged and one
unaged specimen were loaded up to ~3.5 million fatigue
cycles followed by a residual tensile test. The shear, longitudinal, and
peel strain values in adhesive bulk (evaluated by the digital image
correlation (DIC) technique) are significantly higher at the gripped
sides due to the asymmetrical design of the steel brackets. The shear
strength and stiffness of statically and fatigue tested specimens are
found to be identical. The shear strength values are significantly
higher than the requirements following from the design. All specimens
failed by sudden delamination of the composite plate. Post-mortem
analysis showed no corrosion travel at the interface of steel and
adhesive.

Authors: Hu Yanlin , Liu Jinhong , Zhuang Renjie , Zhang Chen , Lin Fei , Wang Jun , Peng Sha , Zhang Wenping
Published: February 2023

HIV-related neuropathic pain (HRNP) is a neurodegeneration that
gradually develops during the long-term course of acquired immune
deficiency syndrome (AIDS) and manifests as abnormal sock/sleeve-like
symmetrical pain and nociceptive hyperalgesia in the extremities, which
seriously reduces patient quality of life. To date, the pathogenesis of
HRNP is not completely clear, and there is a lack of effective clinical
treatment for HRNP. HRNP is becoming a challenge and hot spot for
medical research. Herein, we conducted a systematic review of the
progress of HRNP research in recent years including (1) the etiology,
classification and clinical symptoms of HRNP, (2) the establishment of
HRNP pathological models, (3) the pathological mechanisms underlying
HRNP from three aspects: molecules, signaling pathways and cells, (4)
the therapeutic strategies for HRNP, and (5) the limitations of recent
HRNP research and the future research directions and prospects of HRNP.
This detailed review provides new and systematic insight into the
pathological mechanism of HRNP, which establishes a theoretical basis
for the future exploitation of novel target drugs.
Estimated Energy Requirements for Pumping Pacific Ocean Water to Great Salt Lake
Authors: Sowby Robert B. , Williams Gustavious P. , South Andrew J.
Published: February 2023

Great Salt Lake has receded in recent years. Among many options proposed
to augment inflows is a pipeline from the Pacific Ocean. To inform
discussion, we estimate a lower bound for the ongoing energy
requirements, assuming one-third of the recommended additional inflow
will be pumped through a single, smooth, large-diameter diameter
pipeline along a fictitious, shortest route without mountains.
Accordingly, pumping would require at least 400 megawatts of electricity
during operation, an amount equivalent to a large power plant, or 11%
of Utah’s annual electricity demand. Given current energy prices and
fuel mixes, the electricity would cost over $300,000,000 annually and
emit nearly 1,000,000 metric tons of carbon dioxide annually, equivalent
to 200,000 passenger vehicles. The figures could easily triple with
longer routes, mountainous terrain, higher flows, smaller diameters,
multiple pipelines, less-efficient pumps, and any required treatment. We
present this estimate trusting that feasibility studies will include
complete details.

Published: February 2023

Objective: To measure the effects of cerebral intermittent theta-burst stimulation with physiotherapy on lower extremity motor recovery in patients with incomplete spinal cord injury.Design: Randomized, double-blinded, sham-controlled trial.Subjects: Adults with incomplete spinal cord injury.Methods: A total of 38 patients with incomplete spinal cord injury were randomized into either an intermittent theta-burst stimulation or a sham group. Both groups participated in physiotherapy 5 times per week for 9 weeks, and cerebral intermittent theta-burst stimulation or sham intermittent theta-burst stimulation was performed daily, immediately before physiotherapy. The primary outcomes were lower extremity motor score (LEMS), root-mean square (RMS), RMS of the quadriceps femoris muscle, walking speed (WS), and stride length (SL). Secondary outcomes comprised Holden Walking Ability Scale (HWAS) and modified Barthel Index (MBI). The outcomes were assessed before the intervention and 9 weeks after the start of the intervention.Results: Nine weeks of cerebral intermittent theta-burst stimulation with physiotherapy intervention resulted in improved recovery of lower extremity motor recovery in patients with incomplete spinal cord injury. Compared with baseline, the changes in LEMS, WS, SL, RMS, HWAS, and MBI were significant in both groups after intervention. The LEMS, WS, SL, RMS, HWAS, and MBI scores were improved more in the intermittent theta-burst stimulation group than in the sham group.Conclusion: Cerebral intermittent theta-burst stimulation with physiotherapy promotes lower extremity motor recovery in patients with incomplete spinal cord injury. However, this study included a small sample size and lacked a comparison of the treatment effects of multiple stimulation modes, the further research will be required in the future.
LAY ABSTRACTSpinal cord injury is a serious condition caused by spinal trauma and tumours. Improving the patient’s limb function during recovery poses an important challenge. Transcranial magnetic stimulation technology is a new treatment used to improve nervous system function, which has shown promising results in treating spinal cord injuries in recent years. However, the effect of a specific type of magnetic stimulation, cerebral intermittent theta-burst stimulation, with routine physical therapy on lower extremity motor recovery in patients with incomplete spinal cord injury has not yet been explored. The results of this study suggest that 9 weeks of brain intermittent theta-burst stimulation combined with physical therapy has a positive short-term effect on lower extremity movement and recovery of daily living ability in patients with incomplete spinal cord injury, which might provide new insight into motor rehabilitation for spinal cord injury.
Use of Bedside Lung Ultrasound in Critically Ill Patients
Authors: Vasin Dragan
Published: February 2023

The importance of ultrasound diagnostics in intensive care units is based on the fact that it is a radiological examination method that does not involve the use of ionizing radiation, can be repeated several times in a short period of time, minimally invasive, simple to carry out, does not involve transporting the patient to the radiology service and enables immediate decision-making on diagnosis and further treatment of the patient. Bedside lung US (bLUS) can reliably identify pneumothorax, consolidation, atelectasis, interstitial syndromes, pleural effusions with a high degree of sensitivity. Experts consider it a reliable tool on the basis of which a clinical decision can be made. Chest radiography is the most commonly used visualization method of examination in intensive care units and is certainly used for the diagnosis of ARDS. Radiography cannot monitor changes in the interstitium in a short period of time but ultrasound can detect more discrete changes in the interstitium, which is important for making the decision to extubate the patient. Bedside lung ultrasound is a simple visualization technique for the detection and characterization of conditions in the lung parenchyma. It can detect pleural effusion, interstitial syndrome, pneumothorax with considerable sensitivity and can be a good prognostic criterion for patient extubation
Comparison of Ultrasound Guided Interscalene Block vs Multimodal Analgesia in Shoulder Arthroscopic Surgeries- Prospective, Randomized Controlled Study
Authors: Maheshwari Shivi
Published: February 2023

Introduction: Arthroscopic shoulder surgery is common and associated with severe postoperative pain. Interscalene block is recommended as a most effective method to relieve pain but it is also associated with some serious complications and expertise is required. This study assesses the efficacy, quality of analgesia postoperatively and overall satisfaction of patients undergoing shoulder arthroscopy by comparing ultrasound guided interscalene block with intraarticular morphine and local anaesthesia. Methods: This is prospective, single blind, randomized controlled study involving 46 patients randomized in ratio of 1:1 undergoing elective shoulder arthroscopy where GA was given in all patients out of which 23 received ISB before GA and 23 patients received intra articular injection of morphine and lignocaine at end of surgery. VAS score for postoperative pain, opioid consumption, PONV, patient satisfaction and readiness to discharge criteria was observed at 1, 4, 6, 12 and 24 hours post operatively in both groups. Results: In block group patient, VAS score was significantly low at 1 h and 6 h compared to non-block group. At 12 h both the group had a similar VAS score while at 24 h significantly high VAS score found in Block group patient. There was significant difference in opioid consumption in both groups. PONV, Complication rates, Satisfaction score and ready to discharge criteria were comparable in both groups. Conclusion: ISB provides effective analgesia in early postoperative period and it reduces the overall opioid requirement but the rebound pain which occurs after wearing off the block can reduce its overall benefit and satisfaction as compared to other modalities of multimodal analgesia. So, intra articular LA and opioid infiltration provides equivalent benefits in terms of post op analgesia and satisfaction.
Patient Experience of Communication Options Following Tracheostomy Insertion
Authors: A Thomas
Published: February 2023

The ability to communicate allows us to share our needs, wants, feelings and experiences as well as to pass on information and connect with the people around us. For many patients with tracheostomy in the critical care setting, communication can be challenging. Difficulties communicating can result in psychological and emotional distress, which negatively impact patient experience. We report a single case study detailing the patient experience of communication with a tracheostomy. We explore the range of communication options available to patients with tracheostomy, and the implications for future considerations of care.

Latar Belakang : Antrian di ruang praktek dokter gigi dapat menimbulkan efek yang lebih traumatik daripada perawatan yang akan diterima pasien. Hal ini menyebabkan kecemasan pada pasien meningkat. Dental anxiety dapat berdampak buruk pada perawatan kedokteran gigi yang dapat menyebabkan ketidakberhasilan perawatan. Beberapa cara dapat digunakan untuk menurunkan kecemasan, yaitu secara farmakologis dan non farmakologis. Salah satu cara non farmakologis adalah dengan relaksasi. Beberapa peneliti telah meneliti mengenai terapi musik sebagai cara relaksasi, dimana mendengarkan musik lebih efektif dalam menurunkan respon fisiologis daripada penggunaan obat penenang.Tujuan : untuk mengetahui pengaruh terapi musik yang didengarkan oleh pasien sebelum perawatan gigi terhadap penurunan dental anxiety pasien. Metode : Jenis penelitian adalah kuasi eksperimen. Tiga puluh lima responden yang berada di ruang tunggu pasien dijadikan subjek penelitian. Setelah data identitas dilengkapi, responden dilakukan pengukuran tekanan darah, denyut nadi dan. Tahap selanjutnya adalah pengaplikasian musik kepada pasien selama 10 menit. Setelah pengaplikasian musik, pasien diukur kembali tekanan darah dan nadi. Data yang didapat diolah dengan menggunakan uji paired T Test.Hasil : terdapat penurunan rerata tekanan darah sistolik sebesar 2,89 (p=0,02), penurunan rerata tekanan darah diastolik 0,57 (p= 0,58) dan penurunan rerata denyut nadi setelah terapi musik sebesar 0,1 (p= 0,7)  Simpulan : terdapat pengaruh yang signifikan antara terapi musik pra tindakan dental terhadap penurunan kecemasan pasien yang dilihat dari  tekanan darah sistolik, tetapi tidak terdapat pengaruh yang signifikan pada tekanan darah diastolik dan denyut nadi (p= 0,78)  Kata kunci : dental anxiety, terapi musik, tekanan darah, denyut jantung
PENGARUH LAMA PERENDAMAN RESIN KOMPOSIT NANOHYBRID DALAM SALIVA pH ASAM TERHADAP PERLEKATAN STREPTOCOCCUS MUTANS
Authors: Suparno Nilasary Rochmanita
Published: February 2023

Resin komposit nanohybrid merupakan resin komposit universal yang sering digunakan pada restorasi anterior maupun posterior. Bahan restorasi di dalam rongga mulut berkontak dengan saliva. Kondisi rongga mulut dengan saliva pH asam dapat menyebabkan pertumbuhan optimum bakteri kariogenik seperti Streptococcus mutans. Lama bahan restorasi berkontak dengan saliva pH asam dapat menyebabkan kekasaran permukaan. Kekasaran permukaan bahan restorasi merupakan salah satu faktor penyebab meningkatnya perlekatan bakteri. Penelitian bertujuan untuk mengetahui pengaruh lama perendaman resin komposit nanohybrid dalam saliva pH asam selama 1, 7, dan 14 hari terhadap perlekatan Streptococcus mutans. Sampel resin komposit nanohybrid berbentuk disk sebanyak 27 dibagi menjadi 3 kelompok yang kemudian masing-masing kelompok direndam dalam saliva buatan pH 4,5 selama 1, 7, dan 14 hari. Setelah itu, sampel direndam dalam suspensi Streptococcus mutans selama 24 jam. Perhitungan koloni Streptococcus mutans menggunakan alat colony counter. Data yang diperoleh dianalisis menggunakan uji variansi satu jalur dan post hoc Bonferroni. Hasil penelitian menunjukkan rerata jumlah koloni Streptococcus mutans paling banyak pada kelompok perendaman 14 hari (124,89 CFU/ml), sedangkan paling sedikit pada kelompok perendaman 1 hari (45,11 CFU/ml). Analisis statistik menunjukkan perbedaan yang signifikan antar kelompok (p0,05). Kesimpulan penelitian adalah lama perendaman resin komposit nanohybrid dalam saliva pH asam berpengaruh terhadap perlekatan Streptococcus mutans dan lama perendaman resin komposit nanohybrid selama 1, 7, dan 14 hari dalam saliva pH asam meningkatkan perlekatan Streptococcus mutans. Kata Kunci: resin komposit nanohybrid, lama perendaman, saliva pH asam, Streptococcus mutans
