In the latter part of the 20th century, remarkable developments in new dental materials and technologies were achieved. However, regarding the impact of dental resin-based materials 3D-printed on cellular responses, there have been a limited number of published studies recently. The biocompatibility of dental restorative materials is a controversial topic, especially when discussing modern manufacturing technologies. Three-dimensional printing generates the release of residual monomers due to incomplete polymerization of materials and involves the use of potentially toxic substances in post-printing processes that cannot be completely eliminated. Considering the issue of biocompatibility, this article aims to establish an overview of this aspect, summarizing the different types of biocompatibility tests performed on materials used in 3D printing in dentistry. In order to create this comprehensive review, articles dealing with the issue of 3D printing in dentistry were analysed by accessing the main specialized search engines using specific keywords. Relevant data referring to types of materials used in 3DP to manufacture various dental devices, polymerization methods, factors affecting monomer release, cytotoxicity of unreacted products or post-curing treatments, and methods for assessing biocompatibility were analysed. Although the introduction of new restorative materials used in dental treatments is subject to national and international regulations and standards, it is necessary to investigate them regarding biocompatibility in order to support or deny the manufacturers’ statements regarding this aspect.

Periimplantitis represents an inflammatory disease of the soft and hard tissues surrounding the osseointegrated dental implant, triggering progressive damage to the alveolar bone. Cumulative data have revealed that periimplantitis plays a crucial part in implant failure. Due to the strategic roles of autophagy and its upstream coordinator, the AKT/mTOR pathway, in inflammatory responses, the crosstalk between them in the context of periimplantitis should become a key research target, as it opens up an area of interesting data with clinical significance. Therefore, in this article, we aimed to briefly review the existing data concerning the complex roles played by ROS in the interplay between the AKT/mTOR signaling pathway and autophagy in periimplantitis, in each of the main cell types involved in periimplantitis pathogenesis and evolution. Knowing how to modulate specifically the autophagic machinery in each of the cellular types involved in the healing and osseointegration steps post implant surgery can help the clinician to make the most appropriate post-surgery decisions. These decisions might be crucial in order to prevent the occurrence of periimplantitis and ensure the proper conditions for effective osseointegration, depending on patients’ clinical particularities.

The problems that have arisen in recent years in Romania (the financial crisis, the COVID-19 pandemic, the accelerated growth of inflation and unemployment) have led many people to give less and less importance to dental hygiene, which has led to an increase in the number of people with dental medical problems. In addition, poor information about the need for regular visits to the dentist, the low importance given to this field, and insufficient financial resources led people to turn to dental medical services less often. Moreover, the two-month closure of medical practices during the COVID-19 pandemic made individuals more reluctant to make appointments with dentists for fear of coming into contact with a person infected with the new SARS-CoV-2 virus. All this led to the occurrence of dental complications among patients, which made the number of dental implants increase. Patients suffering from diabetes mellitus present a series of particularities due to a series of risks generated by this condition that may appear in their case. The aim of this research is to identify the main factors that can influence the decision of patients with diabetes mellitus to have a dental implant. The data collection was performed with the help of a questionnaire, and the analysis of the database was performed with the help of IBM SPSS software. Following the analysis, it was noted that this decision is largely influenced by the reputation of the medical practice, the perceived risks, the quality of the materials used, the warranty of the dental implant, the quality of the services provided, and the costs.

Titanium is considered to be a biocompatible material and is used to a great extent in the pharmaceutical and oral implantology fields. While initially, specialists considered that its use does not cause adverse effects on the human body, as time has gone by, it has become clear that its use can lead to the development of certain diseases. The objective of this study was to identify the way in which digital technologies have the capacity to facilitate information regarding the potential long-term harm caused by titanium device toxicity during the COVID-19 pandemic. In this study, a regression model was developed to identify how a series of independent variables have the ability to influence the dependent variable (respondents’ perceptions of how new web technologies have the ability to help future physicians to facilitate information absorption with regard to potential titanium toxicity). The results illustrated that new technologies have the potential to support both the learning process on this topic and the innovation activity by discovering new solutions that will gradually lead to the reduction of the side effects of titanium used in the pharmaceutical and oral implantology fields.

The COVID-19 pandemic has influenced the activities carried out in several fields, including dentistry, to a high extent. The purpose of this paper is to determine the respondents’ perception of the image of dental practices in Romania following the COVID-19 pandemic. In order to fulfil the purpose of the research, a quantitative study was carried out, including data collection with the help of a questionnaire to 306 respondents. A multiple linear regression model was used in order to determine the type and intensity of existing links between the variables. The results illustrated that 50.8% of the variation in the dependent variable (respondents’ perception of the image of dental practices) is explained by the independent variables. The results obtained in this research are very important, both for the dentists who work in private clinics and for the managers who work inside them. They will therefore be aware of the main factors that must be emphasized if they want to improve the image of the medical practice or to increase the number of patients they have.

Reputation is one of the most significant aspects of an organization. It plays a crucial role in Dentistry and Ophthalmology, significantly influencing the relationship between doctors and patients. Reputation management in these two fields is viewed as a strategic process through which dentists and ophthalmologists can establish patients’ trust, thereby ensuring high-quality services and patient satisfaction. The study conducted in this paper aimed to analyze patients’ opinions on how the reputation of medical offices and trust in ophthalmologists and dentists influence their decision to choose a particular office. The results showed that the doctors’ professionalism and the quality of the equipment used are the most critical factors influencing patients’ trust in ophthalmology and dental offices. Additionally, patients primarily evaluate the reputation of these practices based on their previous experiences or recommendations from family and friends.
