The goals of this research are: (1) to compare the survival and prosthetic success of metal-ceramic 3-unit tooth- versus implant-supported fixed dental prostheses; (2) to evaluate the influence of several risk factors on the prosthetic success of tooth- and implant-supported fixed dental prostheses (FPDs). A total of 68 patients with posterior short edentulous spaces (mean age 61.00 ± 1.325 years), were divided into two groups: 3-unit tooth-supported FPDs (40 patients; 52 FPD; mean follow-up 10.27 ± 0.496 years) and 3-unit implant-supported FPDs (28 patients; 32 FPD; mean follow-up 8.656 ± 0.718 years). Pearson-chi tests were used to highlight the risk factors for the prosthetic success of tooth- and implant-supported FPDs and multivariate analysis was used to determine significant risk predictors for the prosthetic success of the tooth-supported FPDs. The survival rates of 3-unit tooth- versus implant-supported FPDs were 100% and 87.5%, respectively, while the prosthetic success was 69.25% and 68.75%, respectively. The prosthetic success of tooth-supported FPDs was significantly higher for patients older than 60 years (83.3%) vs. 40–60 years old (57.1%) (p = 0.041). Periodontal disease history decreased the prosthetic success of tooth- versus implant-supported FPDs when compared with the absence of periodontal history (45.5% vs. 86.7%, p = 0.001; 33.3% vs. 90%, p = 0.002). The prosthetic success of 3-unit tooth- vs. implant-supported FPDs was not significantly influenced by gender, location, smoking, or oral hygiene in our study. In conclusion, similar rates of prosthetic success were recorded for both types of FPDs. In our study, prosthetic success of tooth- versus implant-supported FPDs was not significantly influenced by gender, location, smoking, or oral hygiene; however, history of periodontal disease is a significant negative predictor of success in both groups when compared with patients without periodontal history.

The COVID-19 pandemic highlighted e-learning as a critical component that ensured the continuity of students’ education processes. In this regard, many research groups aim to provide new scientific data about the efficiency and benefits of e-learning for healthcare students. Our study aims to evaluate the attraction of e-learning among medical and dental Romanian students, in association with their preferences as internet and computer consumers. The study enrolled 551 students in medicine from four Romanian Universities of Medicine and Pharmacy, located in major cities (Iași—64.6%, Craiova—19.6%, Timișoara—14.5% and Cluj Napoca—1.3%), mostly females (76.2%), from the first and second years of study (63.7%) or the fourth to sixth years of study (23.3%), aged 18–20 years (53.9%). To investigate their opinions about the efficiency of e-learning, we used an anonymous questionnaire with 31 items regarding advantages (17 items) and possible drawbacks (14 items). The students in medicine had favourable opinions about online learning because these tools are more comfortable (75.2%) and more flexible (60.1%). The main reasons for disagreement were the lack of direct communication and human interaction with teachers (53.2%), limitations due to the particularities of some disciplines that cannot be easily transferred to the online environment (46.4%), and the lack of proper motivation (32.5%). Older students, who liked to use multimedia resources in the learning process and used the internet mainly for information purposes or domestic facilities, had the highest scores for favourable opinions about online learning. The younger students, who did not prefer using multimedia resources in the learning process, also had the highest scores for disagreement regarding online learning. There were no statistically significant differences between genders.

Introduction: The aim of this in vitro study was to compare the quality of marginal sealing at the cervical margins of indirect and direct composite resin restorations in mesio-occluso-distal (MOD) cavities. Material and method: MOD preparations were performed on 30 extracted teeth. The mesial cervical margin of each tooth was relocated using a flow composite resin (Enamel Plus HRi Flow, Micerium, Avegno, GE, Italy), then the samples were divided into three groups. In group A, the cavities were directly restored using a nanohybrid composite resin (Miris 2 Coltène Whaledent, Altstaetten, Switzerland) and a universal adhesive (ScotchBond Universal, 3M ESPE, St. Paul, MN, USA) by the etch-and-rinse strategy, for group B, the restoration procedure was similar but the self-etch strategy was used, and the samples in group C were filled using the inlay technique. Each sample was stored for 48 h in a 2% methylene blue solution, then it was cut in a mesio-distal direction using a Struers Secotom 50 device (Cleveland, OH, USA). The marginal sealing and adhesive interface were assessed for each sample at the cervical margin by optical microscopy (OM) and scanning electron microscopy (SEM). One-way ANOVA and Bonferroni post-hoc tests were used with a significance level of 0.05. Results: Significant differences were recorded within groups A and C, between mesial and distal margins (p = 0.02 in group A and p = 0.043 in group C). Conclusions: The marginal sealing is more effective in MOD inlay restoration compared to direct restorations. Relocation of the cervical margin with flow composite resin and the use of different adhesive strategies do not improve the marginal sealing.

The aim of this study was to explore diabetes mellitus type 2 as a risk factor in the prevalence of chronic apical periodontitis (CAP) in untreated and endodontically treated teeth. The second objective was to describe the correlation between the presence of periapical lesions and blood glucose/glycated hemoglobin levels among diabetic (DM) and non-diabetic patients with endodontically treated or untreated teeth with CAP. Materials and methods: This cross-sectional study was conducted on 90 patients (55 with DM, 35 without DM), admitted to the Oral and Maxillofacial Surgery Department of “St. Spiridon” Hospital in Iași, Romania. Endodontic and perapical status was evaluated using the Periapical Index (PAI) based on clinical and radiological evaluations with blood glucose levels and HbA1c analysis. Statistical analysis included data, correlations and regression analysis, and group comparisons using appropriate parametric or non-parametric tests. DM subjects had a higher mean value of untreated teeth with CAP (2.53 vs. 2.00) compared to the control group (p = 0.010) and a lower mean number of endodontically treated teeth without CAP (1.53 vs. 2.74) compared to the control group (p < 0.001). Diabetic patients also had a higher mean number of root-filled teeth with CAP (3.33 vs. 1.94; p < 0.001). Conclusions: There was a clear association between diabetes and oral pathology, with diabetic patients having fewer teeth, more untreated teeth, and a higher prevalence of periapical lesions. Elevated blood glucose and HbA1c levels indicated that poor metabolic control negatively impacts periapical healing and overall endodontic health.

The success of blended learning programmes, based on digital tools, depends on several factors that significantly influence students’ performance, of which demographics (gender and age group) are the most common. Other factors play an important role too. Among these, we focused on the students’ general attitude towards the digital environment and the importance they attach to it in their daily activities. We investigated a sample of five hundred fifty-one students from four Medical Universities in Romania, mostly females (76.2%), from years 1 and 2 of study (63.7%) and aged between 18 and 20 years (53.9%), and we recorded their general opinion about the effectiveness of four types of teaching tools and the intensity of using Internet services in their daily activities. We conducted univariate (hypothesis testing) and multivariate (two-step clustering) analyses of the recorded responses, and we found that the students’ general behaviour as the users of Internet services significantly influences their choices for certain teaching tools over others. Students who prefer classic oral presentations and PowerPoint presentations are predominantly females, aged between 18 and 20, who use Internet services mainly for communication. Students who prefer educational videos are also mainly females, evenly distributed by age groups; they enjoy using multimedia resources during learning and use Internet services for communication, information or entertainment. Students who prefer the use of online documentary sources are evenly distributed by gender and are over 20 years of age; they also enjoy using multimedia resources during learning and use Internet services mainly for communication and information. The obtained results show that, to optimally combine the teaching tools used in blended learning, it is useful to assess in advance the attitude towards the digital environment of the students to whom it is addressed.

Aim of the study: This literature review analyzes research on the the role of the digital radiography and cone-beam computed tomography (CBCT) in the diagnosis of the endodontic pathology and the monitoring of post-treatment outcomes. Materials and Methods: A systematic search in scientific databases (PubMed, Web of Science), was performed to review studies from the last two decades on the relevance, benefits and drawbacks of these imaging modalities for the diagnosis of periapical lesions, root fractures, root resorption and other endodontic conditions Conclusions: CBCT is a valuable diagnostic tool in endodontics, offering superior accuracy for complex cases, post-treatment evaluation, and surgical planning; however, due to concerns regarding radiation exposure and cost, it should be used selectively, with digital radiography remaining the first-line imaging modality. While digital radiography is preferred for routine follow-ups, CBCT becomes essential in challenging scenarios—such as suspected root fractures, treatment failures, or surgical cases. Recent advancements like dose reduction protocols, enhanced imaging software, and AI-assisted processing further improve its clinical relevance.
