To compare the clinical performance of a glass hybrid restorative system, EQUIA Forte, with that of a nanohybrid resin composite, Tetric EvoCeram, in two-surface class II cavities.
This multicenter, ...randomized controlled clinical study was conducted at four different dental schools. In total, 360 restorations were placed in patients in need of two class-II, two-surface restorations in the molar region of the same jaw. Each patient received one glass hybrid restoration (EQUIA Forte, GC) and one resin composite restoration (Tetric EvoCeram, Ivoclar Vivadent). Two independent evaluators performed a clinical evaluation of each site after 1 week (baseline), 1 year, and 2 years using the criteria of the FDI World Dental Federation (FDI-2).
The estimated survival rates at the 2-year recall were 93.6% and 94.5% for EQUIA Forte and Tetric EvoCeram, respectively. There were no significant differences in the survival rates or in any of the evaluated esthetic, functional or biological properties between EQUIA Forte and Tetric EvoCeram restorations (p ˃ 0.05).
Both the glass-hybrid restorative system and nanohybrid resin composite showed good clinical performance in moderate to large two-surface class II restorations in a 2-year follow-up.
Background: The prevention of preterm delivery (PTD) represents one of the major topics in modern obstetrics. The aim was to design a prospective study and investigate if mid-trimester serum and ...amniotic fluid levels of MCP-1 could predict the occurence of spontaneous PTD. Methods: The study involved 198 women who underwent genetic amniocentesis and blood sampling in the middle of their trimester. After applying the criteria for inclusion in the study, there were 16 respondents in the study group, and 38 respondents in the control group. Level of MCP-1 in amniotic fluid and serum was measured with commercially available enzyme-linked immunosorbent assays (ELISA) and statistical analysis was conducted. Results: There was no statistically significant difference in serum or amniotic fluid MCP1 levels between PTD and the control groups. Conclusion: The results suggest that MCP-1 is probably not the most relevant marker for predicting PTD. This study provides new normative data for MCP-1 levels in amniotic fluid and maternal sera and is a valuable tool for future diagnostic and comparative studies.
Commercial essential oils (EOs) of incense,
Roxb, and mint,
L., were investigated against vaginal bacterial and
isolates for antimicrobial potential and safety use. The antimicrobial activity of EOs ...was investigated through a double-dilution micro-plate assay. A brine shrimp assay was used for the determination of toxicity, while the determination of the chemical composition of EOs was carried out using GS-MS. Obtained minimal inhibitory (MIC) and minimal bactericidal concentration (MBC) point to the activity of mint essential oil (EO) against the multi-resistant
isolate (MIC/MBC at 6.25 µL/mL), while MIC and MBC values for other isolates were reached at higher concentrations (25-50 µL/mL). According to the toxicity assay, the incense EO reached the LC
value at 3.07 µL/mL, while mint EO showed higher toxicity at lower concentrations (0.5 µL/mL) and the LC
could not be determined. The highest antimicrobial potential was obtained for incense against
Although the toxicity assay showed high toxicity of mint EO to the eggs of aquatic crustaceans
, further testing of EO toxicity is proposed, for example on healthy cell-lines. According to the GC/MS spectrometry, the most represented components of mint EO were the oxygenated hydrocarbons L-menthone (20.86%) and menthol (31.86%), and they could be proposed for further antimicrobial and toxicity investigation.
Introduction
Comprehensive and interprofessional undergraduate teaching and training in special care dentistry (SCD) could influence future dentists’ attitudes towards patients with disabilities. The ...aim of the study was to assess the influence of role play as part of SCD training on the attitudes of undergraduates towards patients with disabilities.
Method
The students attending the SCD module during the autumn semester of 2019 comprised our target population. A quasi‐experimental design was used to compare the attitudinal scores between three groups of students exposed to different modalities of SCD teaching: group 1 – didactic teaching (N = 92), group 2 – didactic teaching and clinical training in the dental treatment of children or elderly patients with disabilities (N = 142), group 3 – theoretical teaching and clinical training, accompanied by role play sessions featuring persons with disabilities (N = 20). The contact rate was 100%. The outcomes of the intervention were measured using the altruism scale, which forms part of the International Association for Disability and Oral Health (iADH) Toolbox for measuring attitudes and intended behaviors towards persons with disabilities.
Results
The analysis revealed the two‐factor structure of the nine‐item altruism scale. The first factor was described as the acceptance of oral health care as a universal human right, while the second was the perception of the contribution of marginalised groups, including people with disabilities, to the community. The students participating in the role play scored higher on both factors in comparison to those attending other modes of SCD training.
Conclusion
The presented findings suggested role play as a powerful tool in fostering positive attitudes towards persons with disabilities in the education of dental students and highlighted the importance of multidisciplinary training.
Background/Aim: Autism spectrum disorder (ASD) is pervasive neurodevelopmental condition with raising prevalence over the last decades. Oral health related problems arise mostly due to challenging ...behavior, communication limitation, and resistance to receiving dental treatment. The aim of this retrospective study was to investigate the frequency, quality and type of dental care during routine appointments and under general anesthesia (GA) in persons with ASD. Matreial and Methods: The data were obtained in retrospective cross-sectional study by analyzing patients' records from the central electronic database of the Clinic for Dentistry of Vojvodina. Demographic, medical and dental data were analyzed employing Mann Whitney U test, Kruskal Wallis test and CATREG regression analysis. Results: A total of 51 patients from 4.2-47.6 years of age had an average of 13.2 ±13.5 dental appointments, with 2.27±4.23 treatments done under GA in a period of 7 years. The average number of restored teeth was 3.64±4.42 and 4.64±5.95 teeth were extracted. Only 21.5% of participants regularly attended scheduled appointments. Patients who started oral health care earlier had more teeth restored and extracted during RDT, and were less subjected to treatment under GA. Conclusions: Dental services to patients with ASD are commonly limited to more radical approach comprising multiple teeth extractions and repeated treatment under GA. It is of utmost importance to tailor comprehensive plan for dental care provision in individuals with ASD at earliest possible age.
Background/Aim: The requirements for dental specialties and the number of specialists in each country are unique and strong indicator of the availability and affordability of primary health care for ...children and adolescents. The aim of this study was to determine the pattern, type and the extent of dental services, as well as the influence of regional factors and data on whether services are provided by a pediatric dentist or general dentist have effect on these parameters, based on information obtained from dentists providing dental care to children and youth. Material and Methods: Within the project "Program for the improvement of oral health of children and youth in the Republic of Serbia", supported by the Ministry of Health of Serbia, a research was conducted among dentists involved in dental care for children and youth in Serbia. Data collection from primary health care facilities was performed through a specially designed questionnaire. A total of 445 questionnaires were collected from dentists from 102 health centers in Serbia in the period June - October 2019. Results: There are significant differences between regions in the pattern, type and the extent of dental services. In the quantitative analysis, there are no significant differences in the type of dental services between pediatric and preventive dentistry specialists and general dentists. Conclusions: The data from the conducted research speak in favor of a large daily workload of dentists who deliver oral health care for children and youth in Serbia. Additional multifactorial analysis, which includes epidemiological data from the region, but also environmental, demographic and cultural parameters of oral health could be the basis for improving the provision of preventive dental and preventive oral care
The purpose of this study was to quantify the elastic properties and evaluate microscopical features of raw and boiled metatarsal bovine bone.
The elastic modulus, hardness and microscopic surface of ...raw and cooked bovine metatarsal bone have been investigated using nanoindentation, SEM/EDX and Panasis microscope.
Regarding raw bovine bone, the average elastic modulus was 30.515 ± 6,769 GPa, while the average hardness was 0.5683 ± 0.211 GPa. When it comes to boiled bone corresponding values were 22.298 ± 7.0303 GPa and 0.408 ± 0.199 GPa, respectively. The values for investigated parameters were significantly higher (p < 0.05) in raw bone specimens. Elastic modulus significantly correlated with hardness (p < 0.05). EDX analysis revealed significant decrease in wt% of oxygen in boiled samples (p < 0.05) No significant differences could be observed in SEM images particularly when analysing in smaller magnifications. Using higher magnification, additional branching of the existing voids as well as discrete reorganization and smoother edges of nutrient canals could be observed. The surface of boiled specimens was without the presence of crusts and layering, and no microscopical evidence of structural damage could be observed.
This study provides detailed analysis of hardness, elastic modulus of raw and cooked bovine bone and their relation and changes during exposure to temperature. These results of elastic moduli and hardness could be comparable to similar studies of bovine and human bone tissue, but the careful analysis of experimental design, type of the bone as well as limitations of the employed techniques must be carried out before interpolation of the results to other theoretical, clinical, biomaterial and archeological studies.
Background/Aim: The aim of this study was to conduct a comparative analysis of the national oral health programmes in the Balkan countries, to compare key measures and activities in the ...implementation of the general and specific objectives of the programme, and to analyse the results achieved after the implementation of the programme. Material and Methods: The data were obtained through an electronic search of publicly available documents published by the relevant institutions in the field of dental health care in the Balkan countries. The search terms were: "national programme", "strategy", "action plan", "project", and "oral health". The search was conducted in English and in the native languages of the Balkan Peninsula countries. A comparative analysis of valid documents and those whose validity period has expired was carried out. Results: Bulgaria and the Republic of North Macedonia have valid national preventive programmes. In Cyprus, a strategic plan for the provision of dental services is described. An oral health promotion programme for elementary school children and universal preventive programme for children ("dentist pass") have been implemented in Greece. Serbia has a national preventive programme that has expired, but the programme activities still apply. Albania, Bosnia and Herzegovina, Montenegro, Romania, and Turkey do not have national oral health preventive programmes. Countries in the region with no oral health promotion programmes have poorer oral health indicators compared to countries with existing programmes. Conclusions: While countries in the Balkan Peninsula have made progress in improving the oral health of their inhabitants, the absence of national oral health promotion programmes is striking in many countries in the region. Greater involvement of the community in activities to maintain and improve oral health is needed, as is more comprehensive dental care for vulnerable populations. This paper (Part I) compares national oral health promotion programmes of the Balkan countries, the key measures and activities, and general and specific objectives of the programme.
Aim: The Centre for International Public Policy has undertaken a public opinion research in which we tested the opinions of the citizens of Serbia on the coronavirus epidemic. The respondents had the ...opportunity to express their opinion on measures undertaken by the Serbian Government to combat the virus, to state their trust in the media, as well as the health system in general. In addition, we tested the prevalence of different conspiracy theories among citizens, whether the pandemic gave China a new image in the minds of the people and, most importantly, the level of solidarity among Serbian citizens as well as within the European / international community as a whole. Methods: In seven days, from 8-15th April 2020, we gathered a convenient sample of N=5989 respondents, which makes this the largest public opinion research project in Serbia on the topic of COVID-19 since the start of the epidemic. The electronic questionnaire consisted of 24 questions of mixed and closed type. Results: The findings of this research suggest that citizens of Serbia are not afraid of COVID-19, but are nevertheless cautious (86%). The percentage of those willing to consult a doctor when they notice any symptoms lies at 70%. Half of the respondents do not believe in alternative theories regarding the origin of the COVID-19 virus. The majority of the respondents (55%) hold government officials accountable for spreading panic through public speeches and daily public addresses. Moreover, 60% of the respondents do not trust the Serbian media outlets that are currently reporting on the COVID-19 pandemic. Furthermore, over half of the respondents are prepared to report their neighbour when he or she is coming from abroad and violates the obligation to self-isolate. However, mostly due to the significant fines, 65% of the respondents would not report the elderly when they are breaking the limited-movement restriction measures. Conclusion: As before the epidemic, opinions of the Serbian population on current topics are somewhat polarized. Although the majority of the respondents are cautious, a significant number also believes in conspiracy theories and does not fully trust the information provided by the media or the government.
