Materials and Methods Web-based 16-question survey was sent to members of the Turkish Endodontic Society via social media and email between May 5 to 25, 2020, to obtain information about the members’ demographic characteristics and treatment approaches of seven cases considering COVID-19. The cases represented different endodontic diseases such as symptomatic apical periodontitis, chronic apical periodontitis, acute apical abscess, asymptomatic and symptomatic cases required retreatment, third molar tooth with endodontic symptoms, and symptomatic irreversible pulpitis. Statistical Analysis Statistical analysis was performed using a Chi-square test. The statistical significance was set at α = 0.05. Results Of the 203 respondents, 65.5% were females and 34.5% were males, 62.6% were endodontists and 37.4% were PhD students, 68% worked at a university, 21.2% worked at private clinics, and 10.8% worked at public clinics. Frequency of going to work was mostly once a week (31%). Most commonly performed treatments were “acute apical abscess (32.2%)” and “symptomatic irreversible pulpitis (30.8%).” The respondents most frequently preferred “to prescribe antibiotics and/or painkillers and postpone the treatment” in cases 1 and 6, “to follow-up” in cases 2 and 5, “to extract the tooth” in case 4, and “to start endodontic treatment but postpone the treatment by placing antibacterial medicament into the root canals” in cases 3 and 7 (p < 0.05). Conclusion During a pandemic, the general treatment approach for endodontic emergencies should be to eliminate acute symptoms and minimize the risk of transmission.","PeriodicalId":130020,"journal":{"name":"European Dental Research and Biomaterials Journal","volume":"542 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131243811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods Two occlusive titanium caps were placed on the rat calvaria. One filled with BG particles, the second with DBBM particles, both previously mixed with blood (control). In minocycline HCl loaded groups (experimental), grafts were additionally placed into a minocycline solution. Samples were harvested after 4, 8, and 16 weeks. Half of the samples were embedded in methylmethacrylate for undecalcified histology and the other half was fixed, decalcified, and embedded in paraffin for classical histologic analysis. Results The control groups highlighted osteoconductive and osteoinductive responses associated to BG particles, as well as an osteoconductive reaction, in DBBM sections. The addition of minocycline HCl to BG particles had no measurable influence on the result. In minocycline HCl loaded DBBM sections; however, areas of spontaneous ossification could be observed after 8 and 16 weeks.

Materials and Methods A total of 544 cone-beam computed tomography (CBCT) records of Qatari patients were included in this study. The CBCT images were reviewed by two endodontists. The age, sex, bilateral symmetry, root number, and canal configuration according to Vertucci were tabulated. Results About 97.5% maxillary first molars had three roots and 2.5% had two roots. Maxillary second molar showed 88.2% three roots, 7.3% two roots, 3.3% single root, and 1.2% four roots. For maxillary first molars, the most common Vertucci classifications for the mesiobuccal root were type IV (2-2, 35.9%) and type II (2-1, 21.1%). For maxillary second molars, the most common Vertucci classifications for the mesiobuccal root were type IV (2-2, 27%), type III (1-2-1, 21.3%), type I (1, 19.6%), and type II (2-1, 18.9%). In maxillary first molar, 53.1% right is different from the left and in maxillary second molars, 60.2% right is different from the left. Conclusions In Qatari population, three roots are common in maxillary molars. Mesiobuccal root of maxillary first molars is predominant with Vertucci type IV (2-2) and type II (2-1). Maxillary second molars showed variable Vertucci classification. High bilateral asymmetry was found in canal configuration of the same individuals that should be considered during root canal treatment of two opposite molars.","PeriodicalId":130020,"journal":{"name":"European Dental Research and Biomaterials Journal","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128134690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to assess the relation of vitamin D receptor (VDR) ApaI and TaqI polymorphisms and the susceptibility of periodontitis in Saudi population in Makkah region. Materials and Methods In total, 86 unrelated patients with moderate-to-severe periodontitis and 86 controls were enrolled in this study. Evaluation of the periodontal state was performed by using plaque index, bleeding on probing, probing depth, and attachment loss. Extraction of genomic DNA from peripheral blood and genotyping of VDR gene ApaI G/T (rs7975232) and TaqI T/C (rs731236) polymorphisms were performed by utilizing polymerase chain reaction and restriction digestion. Results There were statistically significant differences between both groups regarding the mean bleeding on probing, mean probing depth, mean plaque index, and the mean attachment level (p < 0.001) indicating that the matching based on the investigated groups was adequate. The examined populations were in Hardy-Weinberg equilibrium. Analysis of the genotype and allele frequencies of both VDR ApaI and TaqI single nucleotide polymorphisms revealed that they were statistically indifferent between the control group and the periodontitis subjects (p> 0.05).

Materials and Methods Different questions were presented regarding possible health care system changes, to gather people’s opinions concerning patients, dentists, and dental clinic tests for contagious viral infections, their history of vaccination, and their readiness to get vaccinated, and finally, how they would feel about visiting their local dental clinics during the COVID-19 pandemic if they faced dental problems. Results Generally, 69% of the respondents believed that the health care system will change in Iraq. A higher percentage of health care workers than nonhealth workers had been vaccinated against hepatitis virus and approximately equal numbers indicated their readiness to be vaccinated against COVID-19 and other contagious viral diseases. Additionally, a higher percentage of health care workers than Non health care workers expressed fear of contracting the infection from dental clinics and the relation was significant. More than two-thirds of respondents stated their inability to visit a dentist because all the dental clinics are closed, and they cannot find a trusted dental clinic. Likewise, the majority preferred to wait until after the outbreak or when the government provides strict control measures and guidelines for dental clinics. Conclusion There was a common belief that the health care system will change after COVID-19 in Iraq. All agreed that dental clinics and the population should be protected against microbial cross-transmission through appropriate infection control measures and vaccination. Future health care changes should include public health education and dental health care personnel training.","PeriodicalId":130020,"journal":{"name":"European Dental Research and Biomaterials Journal","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126960712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photopolymerized materials for dental and biomaterials applications have been progressively used since the 1970s. One of the crucial components in these materials is the photoinitiator (PI) that initiates the polymerization reaction. Synthetic PIs are the most commonly used types, but owing to their drawbacks such as cytotoxicity, insolubility in water, and high cost, research on naturally derived (bio-sourced) PIs is growing, to find an alternative to these synthetic types, especially in the growing field of three-dimensional (3D) printing and bioprinting of biomaterials for tissue engineering applications. Naturally derived PIs are biocompatible, highly water-soluble, and abundant. Naturally derived PIs have been used to prepare experimental dentine bonding agents, dentine primers, photo-crosslinked hydrogels for tissue engineering applications, antibacterial coatings, guided tissue regeneration membranes, and 3D printed biomaterials. An electronic search was done using MEDLINE/PubMed and Scopus databases using the keywords naturally derived, bio-sourced, PIs, dental, biomaterials, 3D printing, and 3D bioprinting, to review potential naturally derived PIs for dental and biomaterials applications. There are a variety of naturally derived PIs with various colors and absorption spectra to choose from, according to the intended application. Most of naturally derived PIs can be used with modern conventional dental light curing units, making them applicable for experimental studies for potential dental and biomaterials applications. Due to their biocompatibility and availability it is expected that in the upcoming years, research on naturally derived PIs and their dental and biomaterials applications will increase especially in the growing field of 3D bioprinting in which cell viability is essential; thus this review was done.","PeriodicalId":130020,"journal":{"name":"European Dental Research and Biomaterials Journal","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124043836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods A descriptive cross-sectional study was conducted at Altamash Institute of Dental Medicine from December 2019 to April 2020. The study was performed among 174 dental graduates (house officers) in Karachi, using a modified, validated, closed-ended questionnaire. For statistical analysis, SPSS software (version 21) was used for descriptive statistics such as percentages and frequencies. The tests applied were independent t-test and Pearson’s correlation to compare and check the correlation between the variables. The p-value used was ≤ 0.05. Results Among 200 dental graduates, only 174 responses were analyzed in SPSS version 21. Females (78.2%) were more in number than males (21.8%), with most of them aged >23 years (59.1%). Of the study population, 78.7% graduates worked 4 to 6 hours per day, and more than half of the graduates (58%) did not do physical exercise outside work. Furthermore, we found that the majority of responders had a fair knowledge of ergonomic principles, where a total of 134 (77%) dental graduates had a positive attitude towards its implementation, however this was not reflected in their practices as 128 (73.6%) graduates has poor practices related to ergonomics. It was also found that knowledge and practices of ergonomics had a weak but significant correlation (r = 0.263, p = 0.001). Moreover, males were more positive about implementing and practicing ergonomics then females with a significant association (p = 0.001). Conclusions A majority of the dental graduates (house officers) in this present study had a reasonable knowledge of ergonomics and its principles also showed positivity but an only small number of them practiced dental ergonomics. This study recommends the need for including dental ergonomics in the academic curriculum of clinical years of both dental undergraduate and postgraduate studies and also conducts workshops to develop faculty to reinforce its importance.","PeriodicalId":130020,"journal":{"name":"European Dental Research and Biomaterials Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128659513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods Acellular dermal scaffolds (ADSs) were prepared by purification of bovine skin. Half of the scaffolds were subjected to high-intensity focused ultrasound energy (HIFU) to modify collagen structure, whereas the other half was used as control. A large skin defect was made in the dorsum of white mice, and the scaffolds were used to cover the induced defects. Wound healing was evaluated histologically after 2, 6, and 12 weeks using common and specific stained sections (n = 20). Statistical Analysis Mean values and standard deviations were calculated for each group, and Student’s t-test was used for statistical analysis (α= 0.05; n = 20). Results After 2 weeks, all examined specimens revealed the presence of inflammatory cellular infiltration and early immature blood vessel formation. After 6 weeks, inflammatory cellular infiltration was reduced, with evidence of maturation of new blood vessels observed for all groups. After 12 weeks, there was a significant increase (F = 124, p < 0.01) in new collagen formation and count of mature blood vessels observed for the HIFU group compared with control. Evidence of remodeling of new collagen fibers and biodegradation of the grafts was also observed.
