The objective of this study was to evaluate the changes in foreign students' satisfaction with the quality of dental and medical education considering the impact of the war in Ukraine. The present study was organized in the form of a questionnaire-based survey among 300 foreign students of Medical Faculty and Faculty of Dentistry in Ukraine. The questionnaire was ad mistered via Google form in a multiple-choice, closed-ended format. Students' satisfaction with environment safety and comfort (p < 0.05) and with the collaborative learning offered (p < 0.05) statistically decreased during the war. Sixty percent of the variability in the mean of students' satisfaction with the quality of education during the war could be explained by the satisfaction rate before the war. The need of migration from Ukraine had a stronger inverse correlation with education quality (r = -0.58) than the fact of the war itself (r = -0.32). The war in Ukraine has had a negative impact on the educational process of foreign medical and dental students, even though the quality of education was considered by students to be as high as before and during the war. The personal effort of professors, the quality of study materials, and adequate technical support could potentially overcome the negative impact of the war on student satisfaction with the quality of medical and dental education by the online mode, if the academic medium could be protected from the direct impact of the war or if the influence of the war within the university community could be minimized.

Introduction: Epidermolysis bullosa (EB) is a genetically inherited disease characterized by recurrent bullae and erosions on the skin with numerous signs of dental caries and poor oral hygiene. The aim of this study was to investigate the general clinical and oral findings of patients with EB. Materials and Methods: In this prospective study, the clinical and oral findings and family history of 26 cases with EB were evaluated. The type of EB, gender, age, parental consanguinity, dental caries, oral findings, distribution of lesions and presence of associated anomalies, clinical and oral findings correlated with gender were recorded. Results: All 26 patients with EB had a history of consanguinity and siblings with EB to varying degrees. In our study, malnutrition, anemia and growth retardation, gastrointestinal system complications, hair thinning, hand and nail deformity, ocular problems and renal disease (in one case) were observed with variable frequencies. When the intraoral findings of the patients were investigated, extensive dental caries in all EB types, enamel hypoplasia in junctional EB (JEB) and the presence of tooth-root to be extracted in dystrophic EB (DEB), intraoral bullae and lesions, ankyloglossia, vestibular sulcus insufficiency, microstomia and maxillary atrophy were observed. Three cases had restorative treatment and one case had prosthetic rehabilitation. Conclusions: Oral involvement can be seen with varying frequencies depending on the type of EB and the severity of the disease. It may result from delayed oral and dental rehabilitation due to physical disabilities, limitations and more pressing medical problems. Microstomy, pain from mucosal lesions, and restricted access to the mouth can be caused by poor oral hygiene. Oral complications and caloric needs of individuals with EB should be determined, and individual prophylaxis should be applied to prevent caries formation and protect teeth.

Pulpal vitality is important for the tooth to maintain its physiological function and preserve its structure. The aim of this study was to evaluate the clinical and radiographic 6- and 12-month treatment success of calcium hydroxide (CH) and calcium silicate materials in indirect pulp treatment (IPT) and direct pulp capping (DPC) in teeth with deep dentin decay. The study included 143 teeth of patients aged 17-69 years with no systemic disease. The study is grouped under 3 main groups (Dycal, Biodentine, TheraCal PT). Direct pulp capping was applied to 65 teeth and IPT to 66 teeth. All teeth were restored with Universal adhesive system and Universal composite (G-Premio Bond; GC Corp., Tokyo, Japan). In the statistical evaluations of the data obtained, 0.05 was accepted as the level of statistical significance. The general success rate in the IPT group was found to be 95.2% for Biodentine (Septodont, SaintMaur-des-Fossés, France), 91.7% for Dycal (Dentsply/Caulk, International Inc. Milford, USA) and 90.1% for TheraCal PT (Bisco Inc., Schaumburg, USA) at both 6 and 12 months. When the clinical and radiographic success was compared at 6 months and 12 months, no statistically significant difference was determined between the materials (p > 0.05). In the clinical and radiographic evaluations at the end of 6-month follow-up in the DPC group, the success rates were determined to be 96.0% for Biodentine, 81.8% for Dycal and 63.2% for TheraCal PT. At 12 months, these rates were 96.0% for Biodentine, 68.2% for Dycal and 63.2% for TheraCal PT. DPC Biodentine was found to be the most successful material (96.0%). At the end of the 12-month follow-up period, it was considered that the 3 materials (Biodentine, Dycal, TheraCal) can be selected for IPT. In DPC, Biodentine was found to be more successful than both calcium silicate containing resin and CH.

Can the Density of Mineralized Dental Tissues (Dentin and Enamel) Be Measured and Compared with 3D Cone Beam Computed Tomography in Cases of Ectodermal Dysplasia? - Article abstract #937003

Background. Number of forensic methods have been proposed for dental age estimation, while parameter of dental age itself is demonstrating a high level of correspondence with chronological age. Analysis of available literature revealed deŢciency of studies regarding applicability of using Demirjian’s age estimation technique among Ukrainian samples for forensic purpose. Objective. To evaluate accuracy of original Demirjian’s dental age estimation method amongsamp le of Ukrainian Transcarpathian children. Materials and Methods. Study was organized as retrospective by the design based on the analysis of 276 digital panoramic X-ray images obtained from the patients of University Dental Clinic aged 6.0-15.99 years old. Dental age estimation was held by the originally proposed Demirjian’s technique. Results. Dental age estimation using Demirjian’s technique provoked overestimation effect on 0.43 years among patients aged 6.0-6.99 years, on 0.49 years among patients aged 7.0-7.99 years, on 0.47 years among patients aged 8.0-8.99 years, on 0.55 years among patients aged 9.0-9.99 years, on 0.51 years among patients aged 10.0-10.99 years, on 0.55 years among patients aged 11.0-11.99 years, on 0.44 years among patients aged 12.0-12.99 years, on 0.45 years among patients aged 13.0-13.99 years, on 0.54 years among patients aged 14.0-14.99 years, on 0.58 years among patients aged 15.0-15.99 years. Conclusion. Demirjian’s dental age estimation technique may be used for forensic purposes among population of children from Ukrainian Transcarpathia, if accuracy of other available dental age estimation methods would not be validated till the moment of needed forensic investigation.
