Aim: This study aims to assess Croatian dentists’ knowledge, attitudes, and use of artificial intelligence (AI) and modern technology, while also identifying perceived barriers to AI and modern technology adoption and evaluating the need for further education and training. Materials and Methods: A cross-sectional survey was conducted in February 2024 among general dentists in Croatia using a self-structured questionnaire. A total of 200 respondents filled out the questionnaire. It included five sections: socio-demographic and professional information, self-assessment of AI and modern technology use, knowledge of AI in dentistry, current innovations and devices used in practice, and barriers to AI and modern technology integration in practice. Data were analyzed using descriptive statistics and a regression analysis to explore relationships between socio-demographic factors and AI knowledge. Results: The mean knowledge of AI systems was 3.62 ± 2.56 out of a possible score of 7, indicating relatively poor knowledge, with 47.5% demonstrating knowledge below the median. Most respondents (76.0%) did not use AI systems and modern technology in practice; however, prosthodontics (13.0%) and oral surgery (10.0%) were identified as the primary fields utilizing these technologies. Respondents rated their knowledge of modern technologies and AI as weak or moderate, with 60.5% engaged in continuous education. Despite 76.0% not using AI daily, 71.0% believed that these technologies could enhance patient care. Participants interested in further training showed significantly better knowledge of AI applications (p = 0.030). Major barriers included acquisition and maintenance costs (59.0%) and financial constraints (58.0%). Conclusions: The study revealed that most respondents had poor knowledge of AI systems. Despite this, there is a recognition of AI’s and modern technology potential in dentistry, emphasizing the need for enhanced education and training in this field.

Abstract Stress, anxiety, and depression have a negative impact on students’ learning and academic performances. In our longitudinal study conducted on dental students from Cluj-Napoca and Oradea, the most representative university centers in north-west of Romania, we evaluated the prevalence and effect of exams on stress, anxiety, and depression, in association with socio-demographic factors. The students self-administered the DASS-21R questionnaire at the beginning of the academic year 2022–2023, before the Christmas holiday, during the winter session, and after the winter session. Students from Cluj-Napoca had higher stress scores at the beginning of the academic year compared to those from Oradea (6.8% vs. 3.7%, P-value

Stress, anxiety, and depression have a negative impact on students' learning and academic performances. In our longitudinal study conducted on dental students from Cluj-Napoca and Oradea, the most representative university centers in north-west of Romania, we evaluated the prevalence and effect of exams on stress, anxiety, and depression, in association with socio-demographic factors. The students self-administered the DASS-21R questionnaire at the beginning of the academic year 2022–2023, before the Christmas holiday, during the winter session, and after the winter session. Students from Cluj-Napoca had higher stress scores at the beginning of the academic year compared to those from Oradea (6.8% vs. 3.7%, P-value < 0.05), especially the females and students with no previous university graduations. Anxiety and depression were significantly more frequently reported by students who study in Cluj-Napoca compared to those who study in Oradea (anxiety 37% vs. 28.2%, P-value < 0.05; depression 17% vs. 11%, P-value < 0.05). We did not observe any significant differences in DASS-21R scores regarding summer jobs, foreign language knowledge, or monthly income. Our results support the needs for interventions regarding stress, anxiety, and depression implemented from the very beginning of university studies and, along with strategies for stress prevention and management of these conditions.

The activity of a dentist reveals itself in numerous aspects, and its regulation is determined by the Deontological Code of the Dental Association, which contains a set of rules that dentists are obliged to follow in the exercise of their profession. The regulation of this activity goes beyond following these precepts because, in the legal relationship that is established whenever an agreement is made with a patient to carry out the treatment deemed appropriate, a series of duties and obligations begin for each party, translated into a reciprocal contract, in which the non-compliance of one of them may result in a legal claim. The objective of this study was to research most court decisions delivered in this century, in Portugal, regarding the activity of dentists when faced with patient claims and to outline a framework that better allows us to understand the regulation of this activity within the scope of the contracts established with them. This includes identifying the patients' sex, the judicial instance, the area of dentistry, the location of the injury, the type of liability, the characterization of the obligation, the basis of responsibility, the alteration of biological assets, and the outcome of the action while also not neglecting the identification of trends and jurisprudential evolutions, should they arise. A survey of judgments from the Portuguese Superior Courts was carried out, which focused on decisions from the Supreme Court of Justice, Court of Appeal of Porto, Court of Appeal of Lisbon, Court of Appeal of Coimbra, Court of Appeal of Guimarães, and Court of Appeal of Évora. To understand the judgments analyzed in this study, a brief approach to various legal concepts and institutions of interest was conducted. A summary characterization of the factual basis of the injured party's claim and the legal framework applied, as well as subsequent decisions by higher courts regarding the activity of dentists, was also elaborated. It was impossible to identify any relationship between the field of dentistry and the characterization of the obligation and the basis of responsibility, nor between the outcomes of the actions and these two parameters mentioned. This is likely due to the small sample size, which, although limited, represented all available published superior court decisions in Portugal related to the proposed topic, and because there were different decisions for similar and identical factual situations due to the various scientific and social conceptions adopted by the courts being susceptible to other interpretations.

Periapical radiography is a regular radiographic procedure performed by dentists. However, at times, it may not be possible to position the image receptor into a patient's mouth in an optimized or practical way. For these cases, some dentists advocated the use of extraoral periapical radiography (EOPA). This literature review aimed to review the dental literature on the use of EOPA. In October 2023, PubMed, Web of Science, and Scopus were searched to identify papers that reported on the use of EOPA, supplemented by manual reference tracing and Google Scholar searches. After screening, 18 papers published between 2003 and 2022 were identified, including 14 original articles and 4 reviews. From very limited and conflicting evidence, it was found that root length/working length measurements between EOPA and IOPA did not significantly differ or EOPA showed inferiority. No data were available to compare EOPA with other extraoral modalities such as panoramic radiography. The technique used in EOPA to visualize posterior teeth in the maxilla and mandible varied across studies, such as the vertical angulation of the primary beam, whether mouth should be opened or closed, and whether a holder should be used or not. At the current time, EOPA probably should not be advocated for regular use. [ABSTRACT FROM AUTHOR]

Biostatistics plays a important role in dental medicine, the development of evidence-based clinical practices, and the advancement of research. Biostatistical methods are used to analyze the efficacy of different treatments, understand disease patterns, and evaluate patient data. Biostatistics helps design studies so that statistically significant results are obtained. Dentists use biostatistics to analyze data collected from clinical trials, such as the effectiveness of various dental treatments. In summary, biostatistics is fundamental in dental medicine for ensuring that clinical practices are effective, evidence-based, and tailored to improve both individual and public oral health outcomes.

The use of infrared (IR) light in dentistry has developed rapidly over the past few decades. Devices do not require an external energy source but can be activated by body heat. IR can be used to improve diagnosis or treatment. Currently, the use of infrared thermography (ITR) in modern medicine is experiencing continuous growth due to the technological advantages of the method in the prevention and monitoring of some diseases, the selection and evaluation of treatments, as well as its high diagnostic sensitivity and specificity reported by specialized studies. Technological advances in the new generations of infrared detectors have led to an increase in the level of precision offered by thermal imaging as an alternative method of medical diagnosis or treatment. The improved thermal sensitivity has contributed to the expansion of the use of IR in all medical fields, including dentistry, in specialities such as endodontics, odontology, periodontics, prosthetics, oral and maxillofacial surgery, TMJ pathology, implantology, allergology, oral pathology, photostimulation. Thermograms can be stored, processed and sent digitally, which makes them compatible with other modern technologies. Colour coded thermograms are easier to interpret. Infrared thermography has numerous advantages, such as speed of realization, comfort for the patient, absence of contraindications and side effects, qualitative evaluation of the examined affection.

Digital transformation in education and relevant calls for action are recognised global priorities aimed to support education and training in the digital age. The experiences from the emergency remote teaching during the COVID‐19 pandemic and recent research findings reveal relevant advantages, challenges, as well as different students and teaching staff perspectives which should be carefully considered and integrated into institutional strategies and policies to improve and enrich students' learning experience. The present study aimed to explore health sciences students' perspectives on online teaching and learning (T&L) in four domains—Satisfaction, Motivation, Interaction and Challenges, and to identify the preferred T&L models or tools. A total of 1,041 responses were collected, including 476 dental medicine (45.7%), 399 pharmacy (38.3%), and 166 medical students (15.9%). Overall Satisfaction was quite high (4.0 ± 1.2; out of 5), followed by satisfactory Interaction (3.4 ± 1.4), whereas Motivation was quite low on average (3.0 ± 1.5). Challenges in online T&L were not markedly expressed (3.0 ± 1.6). The majority of students (46.6%) opted for the blended model as the preferred T&L model. Moodle lessons were perceived as the most useful online T&L tool (45.5% of students), followed by video materials (32.2%). Other T&L tools which require more active student's role, such as short test/quiz, and group or team assignment were declared as less favourable. The findings from the current study may contribute to raising the awareness of academic staff and higher institutions management about the student attitudes and needs related to online T&L and inform institutional planning, decision‐making and policy development.

Introduction: Since the start of the COVID‐19 pandemic, new guidelines for dental practice were published. This research aims to examine the knowledge of dental students and their attitudes towards current guidelines. Materials and methods: The study involved 76 fourth‐year dental medicine students from three public universities in Croatia. A survey questionnaire was developed based on in‐depth interviews and a pilot pretesting. The online questionnaire consisting of 36 questions was published using Google Forms. The survey data were analysed using Microsoft Excel and presented with descriptive statistics. Results: Survey data showed the dental students' knowledge of the guidelines for dental practices is at an insufficient level (average score of 67% correct answers). Students who have come across the guidelines outside the faculty environment through assistantships have demonstrated lesser knowledge (65%) of the guidelines than the ones who do not (68%). A similar trend is observed with dental students who grew up in a family of doctors of dental medicine (61%) and ones who did not (68%). Students also independently assessed their knowledge of the guidelines as moderate (3.15 out of 5), while evaluating the application of current guidelines as very important (4.38 out of 5). Conclusion: Awareness of dental students should be improved by adapting the curriculum of dental studies and increasing the availability of information on current guidelines. Dental students need to be motivated to independently inform themselves about the current guidelines for dental practices, thus improving their clinical work. [ABSTRACT FROM AUTHOR]

Artificial intelligence (AI) is increasingly applied across all disciplines of medicine, including dentistry. Oral health research is experiencing a rapidly increasing use of machine learning (ML), the branch of AI that identifies inherent patterns in data similarly to how humans learn. In contemporary clinical dentistry, ML supports computer-aided diagnostics, risk stratification, individual risk prediction, and decision support to ultimately improve clinical oral health care efficiency, outcomes, and reduce disparities. Further, ML is progressively used in dental and oral health research, from basic and translational science to clinical investigations. With an ML perspective, this review provides a comprehensive overview of how dental medicine leverages AI for diagnostic, prognostic, and generative tasks. The spectrum of available data modalities in dentistry and their compatibility with various methods of applied AI are presented. Finally, current challenges and limitations as well as future possibilities and considerations for AI application in dental medicine are summarized.

Featured Application: This research paper introduces an innovative device designed for the precise measurement of dental arch parameters such as arch perimetry, intermolar distances and arch length. The instrument provides orthodontists with a reliable and efficient means of assessing key metrics, ultimately advancing the field towards more personalized and effective treatment strategies. (1) Background: In the pursuit of enhancing diagnostic precision and treatment planning in orthodontics, accurate measurements in dental study casts of the different parameters of the dental arch stands as a critical element. Measurements such as dental arch perimetry, arch length or intermolar distance play a key role in achieving optimal results in orthodontics. Therefore, the aim of this study is to develop, calibrate and verify a new tool for determining dental arch measurements and to compare these measurements, carried out with the newly fabricated instrument, to two other conventional measurements used in orthodontics. (2) Methods: The study used 40 dental study casts for measuring the three mentioned arch parameters. The measurements were conducted following three methods: with the new instrument, with the help of a digital caliper and with the conventional method using a graduated ruler and metal wire. The difference between the values obtained by measuring with the new instrument and the other two methods was noted out in order to calculate the margin of error. Descriptive statistics, including mean, minimum, maximum, and standard deviation, were computed for all replicates, while normality was assessed using the Kolmogorov–Smirnov and Shapiro–Wilk tests; mean differences were examined using the Friedman test and the Wilcoxon signed-rank test, with statistical significance set at p-values < 0.05. Results: In the case of the arch perimeter measurement, the difference from the conventional measurement was −0.045 mm ± 0.006 and from the digital measurement was 0.025 ± 0.013. The measurement of the anterior arch length results shows that the difference from the conventional measurement was −0.0002 ± 0.014 and from the digital measurement 0.02 ± 0.0006. For the measurement of the intermolar distance of the upper permanent molars, the difference from the conventional measurement was −0.02 ± 0.01 and from the digital measurement −0.02 ± 0.001. The greatest differences were observed in the measurements of the parameter "Arch perimeter", obtaining an average value of −0.045 ± 0.006 mm between the measurement with the new instrument and that with the conventional method using graduated rulers, as opposed to a value of 0.025 ± 0.013 for the difference from the digital measurement. Conclusions: the values obtained using the proposed instrument closely align with those obtained through traditional measuring methods like the graduated ruler and metal wire, demonstrating comparable results. Additionally, the measurements closely match those achieved through digital measurement using electronic calipers, showcasing the instrument's accuracy in comparison to established techniques.

Background: Previous studies have predominantly measured e-professionalism through perceptions or attitudes, yet there exists no validated measure specifically targeting the actual behaviors of health care professionals (HCPs) in this realm. This study addresses this gap by constructing a normative framework, drawing from 3 primary sources to define e-professional behavior across 6 domains. Four domains pertain to the dangers of social networking sites (SNSs), encompassing confidentiality, privacy, patient interaction, and equitable resource allocation. Meanwhile, 2 domains focus on the opportunities of SNSs, namely, the proactive dissemination of public health information and maintaining scientific integrity. Objective: This study aims to develop and validate 2 new measures assessing the e-professional behavior of doctors of medicine (MDs) and doctors of dental medicine (DMDs), focusing on both the dangers and opportunities associated with SNSs. Methods: The study used a purposive sample of MDs and DMDs in Croatia who were users of at least one SNS. Data collection took place in 2021 through an online survey. Validation of both indexes used a formative approach, which involved a 5-step methodology: content specification, indicators definition with instructions for item coding and index construction, indicators collinearity check using the variance inflation factor (VIF), external validity test using multiple indicators multiple causes (MIMIC) model, and external validity test by checking the relationships of the indexes with the scale of attitude toward SNSs using Pearson correlation coefficients. Results: A total of 753 responses were included in the analysis. The first e-professionalism index, assessing the dangers associated with SNSs, comprises 14 items. During the indicators collinearity check, all indicators displayed acceptable VIF values below 2.5. The MIMIC model showed good fit (χ213=9.4, P =.742; χ2/df=0.723; root-mean-square error of approximation<.001; goodness-of-fit index=0.998; comparative fit index=1.000). The external validity of the index is supported by a statistically significant negative correlation with the scale measuring attitudes toward SNSs (r=–0.225, P <.001). Following the removal of 1 item, the second e-professionalism index, focusing on the opportunities associated with SNSs, comprises 5 items. During the indicators collinearity check, all indicators exhibited acceptable VIF values below 2.5. Additionally, the MIMIC model demonstrated a good fit (χ24=2.5, P =.718; χ2/df=0.637; root-mean-square error of approximation<0.001; goodness-of-fit index=0.999; comparative fit index=1.000). The external validity of the index is supported by a statistically significant positive correlation with the scale of attitude toward SNSs (r=0.338; P <.001). Conclusions: Following the validation process, the instrument designed for gauging the e-professional behavior of MDs and DMDs consists of 19 items, which contribute to the formation of 2 distinct indexes: the e-professionalism index, focusing on the dangers associated with SNSs, comprising 14 items, and the e-professionalism index, highlighting the opportunities offered by SNSs, consisting of 5 items. These indexes serve as valid measures of the e-professional behavior of MDs and DMDs, with the potential for further refinement to encompass emerging forms of unprofessional behavior that may arise over time.

The absence of one or multiple teeth can be remedied through the utilization of removable partial dentures, which possess a similar aesthetic quality to natural teeth and generally present a less intrusive and more cost-effective alternative to other tooth replacement options. Removable partial dentures serve as an excellent esthetic remedy for lost teeth and a suitable interim solution prior to the implementation of more extensive periodontic treatments. The denture base not only functions as a cornerstone for the denture, providing stability and retention within the mouth but also must be created from biocompatible materials, poses no risk in the oral cavity and to closely resemble the patient’s natural gum color and shape.

Intercultural education in the Romanian space is an insufficiently addressed topic. Against the background of the significant increase in foreign students who choose to study at the University of Medicine and Pharmacy in Craiova, as well as the implementation of study programs in English which in turn have attracted many students from both European and non-EU countries we decided to develop a study aimed at the socio-cultural integration capacity of students at the Faculty of Dental Medicine in Craiova with a teaching program in English. The general objectives of the study aim at the following aspects: the degree of social integration of students; degree of satisfaction of educational needs; the effectiveness of the feedback system; problems encountered throughout the years of study: conflicts, discrimination phenomena, etc. the quality of courses and internships compared to their countries of origin. The target group of the study is represented by the students of Dental Medicine from Craiova, within the teaching program in English, study years I-III. The students who participated in this study come from both EU and non-EU member states. The total number of students enrolled in this study program is 93, and in our study a total of 71 respondents gave their informed consent to complete the distributed questionnaire.

Periapical radiography is a routine radiographic procedure performed by dentists on a daily basis. It can be taken with two techniques, the paralleling technique (P tech) and the bisecting angle technique (B tech). This systematic review aimed to identify the relevant literature, compare the use of P and B techs across various dental specialties, and determine the most appropriate technique to be used for different purposes in taking periapical radiographs. In January 2023, we searched PubMed, Web of Science, Scopus, and Google Scholar to identify the studies that compared the two radiographic techniques. The search string was: (paralleling AND ("bisecting angle" OR "bisected angle")). Manual reference tracing was also performed to identify the studies potentially missed. After screening, 26 studies were included for the qualitative review. The 26 included studies were published between 1976 and 2021. Ten of the studies were about general dentistry (dental radiology in general applications), whereas another ten studies were related to endodontics, such as working length estimation. Most studies advocated the use of the P tech for general, endodontics, implantology, and other indications. B tech was advocated for patients with a low palatal height. More future studies are needed to evaluate their performance in different scenarios with standardized equipment and radiographic positioning. [ABSTRACT FROM AUTHOR]

Abstract Background Social networking sites (SNSs) have penetrated all aspects of health care professionals’ (HCPs’) professional and private lives. A new term, e-professionalism, has emerged, which describes the linking of traditional values with this new dynamic online environment for HCPs. The four aims of this study were: (1) to examine their SNS prevalence and usage habits, (2) to examine their perception of e-professionalism, (3) to develop an e-professionalism assessment compatibility index and (4) to investigate their tendencies and differences in values of the e-professionalism assessment compatibility index (ePACI). Methods A cross-sectional study was conducted among MDs and DMDs in Croatia via email using a questionnaire. The questionnaire was distributed to all MDs and DMDs who were members of their respective chambers. In addition to descriptive statistics, Chi-square or Fisher’s exact test when appropriate, t-test, ANOVA and Mann–Whitney U tests were used to determine differences between groups. A principal component analysis (PCA) with varimax rotation was used to investigate dimensionality. Results of the PCA were compared to the coding based on the Social Media e-Professionalism rubric in order to create the ePACI. Results Of the 1013 gathered responses, 753 were from valid SNS users and suitable for further analysis. Facebook (91.6%) and Instagram (63.1%) were the predominant SNSs used. Both groups have a good understanding of e-professionalism. The newly developed ePACI deviates slightly in the “conservative” direction in the cases of both, MDs (t506 = 19.033, p

The medical use of cannabis has a very long history. Although many substances called cannabinoids are present in cannabis, Δ9tetrahydrocannabinol (Δ9-THC), cannabidiol (CBD) and cannabinol (CBN) are the three main cannabinoids that are most present and described. CBD itself is not responsible for the psychotropic effects of cannabis, since it does not produce the typical behavioral effects associated with the consumption of this drug. CBD has recently gained growing attention in modern society and seems to be increasingly explored in dentistry. Several subjective findings suggest some therapeutic effects of CBD that are strongly supported by research evidence. However, there is a plethora of data regarding CBD's mechanism of action and therapeutic potential, which are in many cases contradictory. We will first provide an overview of the scientific evidence on the molecular mechanism of CBD's action. Furthermore, we will map the recent developments regarding the possible oral benefits of CBD. In summary, we will highlight CBD's promising biological features for its application in dentistry, despite exiting patents that suggest the current compositions for oral care as the main interest of the industry.

This article provides an overview of the history of the dental medicine as both science and profession. We must not forget that today's advanced dental medicine landscape is highly indebted to the trials and errors of yesteryear, to the knowledge of various civilizations that have contributed to shaping the framework of the field as it exists today. Ranging from tooth drilling in the Ancient Indus Valley to modern reconstruction techniques, the evolution of dental medicine practices, as evidenced by various archaeological discoveries, also provides a fascinating glimpse into the way society has changed as a whole throughout the millennia, specifically regarding general approaches to health, patient-doctor interaction and treatment of diseases.

Abstract Aim In this study, we aimed to describe a multimedia-supported manikin system, compare the new manikin with the traditional manikin and evaluate its effectiveness in preclinical dentistry training. Methods A total of 150 students participated in this study. Amongst these students, 71 in the 2015-year group used traditional manikins (Group TM) for preclinical training courses (endodontics training courses and prosthodontics training courses), and 79 in the 2016-year group used manikins with a multimedia system (Group MM). The scores of the training courses between the two groups were compared. A questionnaire survey was used to collect opinions of the students in Group MM on their experience of using the multimedia-supported manikin system in the preclinical training. Results In the endodontics training courses, the scores of Group MM were higher than those of Group TM, but there was no significant difference (P = 0.379 > .05). However, the scores of prosthodontics training courses in Group MM were significantly higher than those in Group TM (P = 0.018

The personalized regenerative therapeutic strategies applicable in the structural and functional repair of maxillofacial/dental defects are expected to extend beyond the limits of what is currently possible in the management of dentofacial anomalies and treating malocclusions. The application of undifferentiated stem cells (SCs), including signaling molecule control and individualized tissue engineering based on targeted therapies, has been proposed to overcome therapeutic limitations and complications associated with treatments for craniofacial defects, including severe orthodontic discrepancies. This scoping, prospective review discusses comprehensively the current knowledge and prospects for improving clinical outcomes by the application of novel cell-required and cell-free regenerative strategies in biomedicine. The existing evidence, although scant, suggests that patients receiving an orthodontic treatment could benefit from precise tissue augmentation, allowing enhancement of tooth movement generated by orthognathic forces; faster, more predictable alignment of dental arches; optimal management of periodontal complications; and prevention of external root resorption. Ultimately, enriching orofacial tissues and "customizing" the repair of congenital/acquired defects in the craniofacial region can be vastly enhanced to provide a positive therapeutic outcome and improve patients' quality of life.

Background and Objectives: Implant rehabilitation of complete edentulous arches has become more and more popular because of the increased access of the population to this type of treatment. Furthermore, the development of new rehabilitation procedures can be applied in most clinical cases, including in those with severe atrophy. Hence, this study aimed to assess the functional changes that can occur in the stomatognathic system after implant rehabilitation procedures. Materials and Methods: A total of 63 patients were accepted in the study. They were divided into a first control (dentate) group (CG) and a second study group (edentulous, SG). For the latter, 30 patients received 204 two-stage implants immediately loaded with provisional prostheses. Surface electromyography (EMG) was assessed at the time of prostheses fixation, while for some patients it was applied six months after the fixation of the fixed prostheses, as well. These supplemental investigated patients formed a third, follow-up study group (FSG). All assessments were performed during the processes of clenching and mastication. The obtained data of the two study groups, SG and FSG, were compared with those of the control group, CG. Results: No statistical differences were found in the electrical muscular activity between the study and control groups during both clenching and mastication (p > 0.05). In addition, there were no differences within the same study group, both initially and after 6 months. The only changes were noticed between static and dynamic values for the right masseter muscle in the follow-up group FSG (p = 0.008). Deviations of the overlapping coefficients were similar for all groups (p = 0.086): for CG, 20.5%, median 11.1 (min. 0, max. 104); for SG, 21.4%, median 12.2 (min. 0, max. 103); for FSG, 36.1%, median 26.9 (min. 0, max. 160). This revealed no neuromuscular adaption to the prostheses. Conclusions: Implant-prosthetic rehabilitation led to an EMG activity that was similar to that of dentate patients immediately after the placement of the fixed implant-supported prostheses. Moreover, the measured values did not change after six months of functioning for all evaluated parameters. This may point to an immediate restoration of the muscle contraction capacity, without the necessity of adaptation over time. The study serves as an argument for the application and reliability of the immediate fixed implant-supported prostheses from the perspective of muscle adaptation and functioning.

Introduction: Artificial intelligence (AI), including its subfields of machine learning and deep learning, is a branch of computer science and engineering focused on creating machines capable of tasks requiring human-like intelligence, such as visual perception, decision-making, and natural language processing. AI applications have become increasingly prevalent in dental medicine, generating high expectations as well as raising ethical and practical concerns., Methods: This critical review evaluates the current applications of AI in dentistry, identifying key perspectives, challenges, and limitations in ongoing AI research., Results: AI models have been applied across various dental specialties, supporting diagnosis, treatment planning, and decision-making, while also reducing the burden of repetitive tasks and optimizing clinical workflows. However, ethical complexities and methodological limitations, such as inconsistent data quality, bias risk, lack of transparency, and limited clinical validation, undermine the quality of AI studies and hinder the effective integration of AI into routine dental practice., Conclusions: To improve AI research, studies must adhere to standardized methodological and ethical guidelines, particularly in data collection, while ensuring transparency, privacy, and accountability. Developing a comprehensive framework for producing robust, reproducible AI research and clinically validated technologies will facilitate the seamless integration of AI into clinical practice, benefiting both clinicians and patients by improving dental care., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Social networking sites (SNSs) have penetrated all aspects of health care professionals' (HCPs') professional and private lives. A new term, e-professionalism, has emerged, which describes the linking of traditional values with this new dynamic online environment for HCPs. The four aims of this study were: (1) to examine their SNS prevalence and usage habits, (2) to examine their perception of e-professionalism, (3) to develop an e-professionalism assessment compatibility index and (4) to investigate their tendencies and differences in values of the e-professionalism assessment compatibility index (ePACI). Methods: A cross-sectional study was conducted among MDs and DMDs in Croatia via email using a questionnaire. The questionnaire was distributed to all MDs and DMDs who were members of their respective chambers. In addition to descriptive statistics, Chi-square or Fisher's exact test when appropriate, t-test, ANOVA and Mann–Whitney U tests were used to determine differences between groups. A principal component analysis (PCA) with varimax rotation was used to investigate dimensionality. Results of the PCA were compared to the coding based on the Social Media e-Professionalism rubric in order to create the ePACI. Results: Of the 1013 gathered responses, 753 were from valid SNS users and suitable for further analysis. Facebook (91.6%) and Instagram (63.1%) were the predominant SNSs used. Both groups have a good understanding of e-professionalism. The newly developed ePACI deviates slightly in the "conservative" direction in the cases of both, MDs (t506 = 19.033, p < 0.001) and DMDs (t245 = 12.991, p < 0.001). HCPs who are older (r = 0.308, p < 0.001), who have fewer SNS profiles (rs = −0.142, p < 0.001), and who access their profiles less frequently (r = −0.166, p < 0.001) have statistically significantly more conservative ePACI values. Conclusions: MDs and DMDs in Croatia are frequent SNS users, with Facebook and Instagram being the main SNSs used. Both groups have a good understanding of e-professionalism. The newly developed ePACI deviates slightly towards the conservative side regarding perception of the e-professionalism content for both groups. The development of the ePACI, and its subsequent usage in further research, will have a direct influence in its validation, gathering comparable data, and be able to direct efforts in oversight, regulation and education.

Cannabidiol (CBD) has been gaining increased attention in contemporary society but seems to have been little explored in dentistry. This scoping review mapped the scientific and technological scenarios related to the use of CBD in dentistry. Peer-reviewed publications were searched in five international databases, patents were searched in five technological platforms. In total, 11 articles and 13 patents involving CBD in dentistry-related applications were included. The countries contributing to most articles were Brazil (27.3%) and USA (18.2%). The studies involved experiments on animals (63.6%) and/or using bacteria or cells (36.4%), and no clinical study was found. Three different applications of CBD were observed: periodontal therapy (45.4%), aid for bone regeneration (27.3%), and general use in oral therapies (27.3%). Patent inventors were based in China (53.8%) or USA (46.2%). The patent claims were mainly compositions for oral care, tooth whitening, injury repair, antifungal, anti-inflammatory, and analgesic effects. A total of 76.9% of the patents were filed in association with a company. In general, research suggests that CBD has promising biological properties for applications in dentistry, whereas patents indicate that the current interest of industry relies on compositions for oral care. There appears to be extensive room available for research and technological applications of CBD in dentistry. [ABSTRACT FROM AUTHOR]

Objectives: The objective of this study was to analyse the pattern of medication prescribing among dental practitioners in the Republic of Croatia and to compare it with general medical practice patterns at the national level. Methods: Data on drug prescriptions were obtained from the Croatian Health Insurance Fund. The number of dentist prescriptions, the cost of medicine denominated in the national currency (Croatian Kuna [HRK]), and the number of packages and days prescribed have been included in the analysis. Results: Results indicate that there was an increase in medication prescribing(+5.7%) by dentists, with antimicrobials comprising the majority, whereas national medical antimicrobial prescribing had slightly decreased. Antibiotics accounted for 80% of all dentists’ prescriptions, with penicillins being the most commonly prescribed. In particular, amoxicillin with clavulanic acid accounted for 56.4% of all antibiotics prescribed. Such broad-spectrum antibiotics were prescribed more frequently than those of narrow-spectrum. Antibiotics were followed by nonsteroidal anti-inflammatory drugs, with prescribing frequency for ibuprofen increasing by 75%. Conclusion: Current trends show an increase in the overall prescription rate for all medications prescribed by dentists. The largest increase was observed for the broad-spectrum amoxicillin with clavulanic acid, and ibuprofen. As the apparent widespread use of broad-spectrum antibiotics by dentists in Croatia is in contrast to national and international recommendations for antibiotic stewardship, there is a need for further prospective investigation and possible provider education and guidelines.

Aim: In this study, we aimed to describe a multimedia-supported manikin system, compare the new manikin with the traditional manikin and evaluate its effectiveness in preclinical dentistry training. Methods: A total of 150 students participated in this study. Amongst these students, 71 in the 2015-year group used traditional manikins (Group TM) for preclinical training courses (endodontics training courses and prosthodontics training courses), and 79 in the 2016-year group used manikins with a multimedia system (Group MM). The scores of the training courses between the two groups were compared. A questionnaire survey was used to collect opinions of the students in Group MM on their experience of using the multimedia-supported manikin system in the preclinical training. Results: In the endodontics training courses, the scores of Group MM were higher than those of Group TM, but there was no significant difference (P = 0.379 >.05). However, the scores of prosthodontics training courses in Group MM were significantly higher than those in Group TM (P = 0.018 <.05). The questionnaire results indicated that the students in Group MM were satisfied with the device in usability, clarity, effectiveness and improvement in operation proficiency. Conclusions: In the groups studied, for preclinical dental training, the multimedia-supported manikin system was a good alternative to traditional manikin in preclinical dentistry training.

Oral frailty associated with oral hypokinesia may cause dementia. Functional near-infrared spectroscopy (fNIRS) can be used while the participants are in seating position with few restrictions. Thus, it is useful for assessing brain function, particularly oral motor activity. However, methods for identifying oral motor cortex (OMC) activation via the scalp have not been established. The current study aimed to detect OMC activation, an indicator of activity phase ratio (APR), which reflects increased oxygen consumption (0 < [deoxyhemoglobin (ΔDeoxyHb) or 0 < {[ΔDeoxyHb- oxyhemoglobin (ΔOxyHb)/√2]}, via fNIRS to accurately identify local brain activity. The APR, calculated via zero-set vector analysis, is a novel index for quantifying brain function both temporally and spatially at rest and during tasks. In total, 14 healthy participants performed bite tasks for 3 s per side for 10 times while in the sitting position. Then, time-series data on concentration changes in ΔOxyHb and ΔDeoxyHb were obtained via fNIRS. The anatomical location of the OMC was determined using a pooled data set of three-dimensional magnetic resonance images collected in advance from 40 healthy adults. In the zero-set vector analysis, the average change in ΔOxyHb and ΔDeoxyHb concentrations was utilized to calculate the APR percentage in 140 trials. The significant regions (z-score of ≥2.0) of the APR and ΔOxyHb in the task were compared. During the bite task, the APR significantly increased within the estimated OMC region (56–84 mm lateral to Cz and 4–20 mm anterior to Cz) in both the right and left hemispheres. By contrast, the ΔOxyHb concentrations increased on the bite side alone beyond the OMC region. The mean APR at rest for 2 s before the task showed 59.5%– 62.2% in the left and right OMCs. The average APR for 3 s during the task showed 75.3% for the left OMC and 75.7% for the right OMC during the left bite task, and 65.9% for the left OMC and 80.9% for the right OMC during the right bite task. Interestingly, the average increase in APR for the left and right OMCs for the left bite task and the right bite task was 13.9% and 13.7%, respectively, showing almost a close match. The time course of the APR was more limited to the bite task segment than that of ΔOxyHb or ΔDexyHb concentration, and it increased in the OMC. Hence, the APR can quantitatively monitor both the resting and active states of the OMC in the left and right hemispheres. Using the zero-set vector-based fNIRS, the APR can be a valid indicator of oral motor function and bite force. [ABSTRACT FROM AUTHOR]

Background: Dental caries is a prevalent, complex, chronic illness that is avoidable. Better dental health outcomes are achieved as a result of accurate and early caries risk prediction in children, which also helps to avoid additional expenses and repercussions. In recent years, artificial intelligence (AI) has been employed in the medical field to aid in the diagnosis and treatment of medical diseases. This technology is a critical tool for the early prediction of the risk of developing caries. Aim: Through the development of computational models and the use of machine learning classification techniques, we investigated the potential for dental caries factors and lifestyle among children under the age of five. Design: A total of 780 parents and their children under the age of five made up the sample. To build a classification model with high accuracy to predict caries risk in 0–5-year-old children, ten different machine learning modelling techniques (DT, XGBoost, KNN, LR, MLP, RF, SVM (linear, rbf, poly, sigmoid)) and two assessment methods (Leave-One-Out and K-fold) were utilised. The best classification model for caries risk prediction was chosen by analysing each classification model's accuracy, specificity, and sensitivity. Results: Machine learning helped with the creation of computer algorithms that could take a variety of parameters into account, as well as the identification of risk factors for childhood caries. The performance of the classifier is almost unbiased, making it generalizable. Among all applied machine learning algorithms, Multilayer Perceptron and Random Forest had the best accuracy, with 97.4%. Support Vector Machine with RBF Kernel (with an accuracy of 97.4%) was better than Extreme Gradient Boosting (with 94.9% accuracy). Conclusion: The outcomes of this study show the potential of regular screening of children for caries risk by experts and finding the risk scores of dental caries for any individual. Therefore, in order to avoid dental caries, it is possible to concentrate on each individual by utilizing machine learning modelling. [ABSTRACT FROM AUTHOR]

The successful application of honey in wound care management has been achieved due to honey's potent antibacterial effects, characterised by its multifactorial action. Impressive clinical efficacy has ignited its further use in diverse clinical disciplines, including stomatology. Indeed, there is increasing usage of honey in dental medicine as a preventive or therapeutic remedy for some periodontal diseases mainly associated with bacteria, such as dental caries, gingivitis and mucositides. Dental caries is undoubtedly a major oral health problem worldwide, with an increasing tendency of incidence. The purpose of this perspective review is to describe the recent progress in the laboratory and clinical use of honey in the prevention of dental caries, with emphasis on the antibacterial and antibiofilm effects of honey. The role of honey in the cariogenic process is also discussed. In addition, the quality of honey and the urgent in vitro evaluation of its antibacterial/antibiofilm properties before clinical use are highlighted. Findings based on data extracted from laboratory studies demonstrate the pronounced antibacterial effect of different honeys against a number of periodontal pathogens, including Streptococcus mutans. Although the promising antibiofilm effects of honey have been reported mainly against S. mutans, these results are limited to very few studies. From a clinical point of view, honey significantly reduces dental plaque; however, it is not superior to the conventional agent. Despite the positive in vitro results, the clinical effectiveness of honey in the prevention of dental caries remains inconclusive since further robust clinical studies are needed.

Background: Social media presence among health care professionals is ubiquitous and largely beneficial for their personal and professional lives. New standards are forming in the context of e-professionalism, which are loosening the predefined older and offline terms. With these benefits also come dangers, with exposure to evaluation on all levels from peers, superiors, and the public, as witnessed in the #medbikini movement. Objective: The objectives of this study were to develop an improved coding scheme (SMePROF coding scheme) for the assessment of unprofessional behavior on Facebook of medical or dental students and faculty, compare reliability between coding schemes used in previous research and SMePROF coding scheme, compare gender-based differences for the assessment of the professional content on Facebook, validate the SMePROF coding scheme, and assess the level of and to characterize web-based professionalism on publicly available Facebook profiles of medical or dental students and faculty. Methods: A search was performed via a new Facebook account using a systematic probabilistic sample of students and faculty in the University of Zagreb School of Medicine and School of Dental Medicine. Each profile was subsequently assessed with regard to professionalism based on previously published criteria and compared using the SMePROF coding scheme developed for this study. Results: Intercoder reliability increased when the SMePROF coding scheme was used for the comparison of gender-based coding results. Results showed an increase in the gender-based agreement of the final codes for the category professionalism, from 85% in the first phase to 96.2% in the second phase. Final results of the second phase showed that there was almost no difference between female and male coders for coding potentially unprofessional content for students (7/240, 2.9% vs 5/203, 2.5%) or for coding unprofessional content for students (11/240, 4.6% vs 11/203, 5.4%). Comparison of definitive results between the first and second phases indicated an understanding of web-based professionalism, with unprofessional content being very low, both for students (9/222, 4.1% vs 12/206, 5.8%) and faculty (1/25, 4% vs 0/23, 0%). For assessment of the potentially unprofessional content, we observed a 4-fold decrease, using the SMePROF rubric, for students (26/222, 11.7% to 6/206, 2.9%) and a 5-fold decrease for faculty (6/25, 24% to 1/23, 4%). Conclusions: SMePROF coding scheme for assessing professionalism of health-care professionals on Facebook is a validated and more objective instrument. This research emphasizes the role that context plays in the perception of unprofessional and potentially unprofessional content and provides insight into the existence of different sets of rules for web-based and offline interaction that marks behavior as unprofessional. The level of e-professionalism on Facebook profiles of medical or dental students and faculty available for public viewing has shown a high level of understanding of e-professionalism.

Bone metastases affect a large number of oncological patients and can determine complications that can impact the quality of life of our patients and further translate into lessen treatment results and overall survival. Treatment with bisphosphonates (BP) has proven its efficacy in preventing the development of the complications related to bone metastases. BP are well tolerated in general but severe adverse events can occur, like osteonecrosis of the jaw (ONJ). Besides ONJ there are other dental and maxillofacial complications determined by BP, complications that by elementary preventive measures can be avoided.

Introduction: Aim of this study was to investigate the motives for studying dental medicine of pupils and students accepted for first semester. Methods: Motives of pupils from secondary schools (grades 10–12) around Tübingen and accepted students at the Dental School Tübingen were evaluated using a five‐level Likert scale. Information about age, gender, family, apprenticeship and university enrolment was also included in the assessment. Results: A total of 402 out of 409 participants filled out the questionnaires. Of these, 390 (280 females and 110 males) could be evaluated; the mean age was 17.4 years. Sixty‐one planned an apprenticeship and 64 already completed it; 93 were readily accepted at university. All participants highly rated the motives "help patients" and "good career prospects." As next, women chose "diversified activity" and men "scientific interest." Participants who planned an apprenticeship rated "help patients" significantly higher than the other participants, whilst the motive "high responsibility of the dental profession" amongst interviewees with completed apprenticeship was highly significant in comparison with the rest. Conclusion: Empathy for patients and high responsibility of the dental profession are more important than prestige or social standing. An apprenticeship seems to greatly influence the career choice by giving more weight to "high responsibility of the dental profession." In future, such results can help universities design selection tests to target specific groups. The high proportion of female dentists and the attitude towards work and family of the generations Y and Z may bring change to the traditional practice model in Germany. [ABSTRACT FROM AUTHOR]

he role of platelets is to trigger the inflammatory response which, in turn, will trigger the presence of tissue growth factors that will be involved in the tissue repair process. Platelet rich plasma (PRP) is a concentrate used for therapeutic purposes which has become increasingly used by treating various dermatological pathologies, musculoskeletal disorders and not least with increasingly frequent indications in the pathology of the oro-dento-maxillare sphere, as a consequence of its potential to repair tissues with reduced regeneration capacity and apparent harmlessness. PRP is defined as a plasma preparation with a higher platelet content than found in the blood flow of a healthy individual (200 000 per microliter) typically 5 times higher. This study in the literature aims to review the biological basis of PRP, its preparation and processing for its use as well as its main applications. At the same time, another derivative of practical importance in dental medicine, PRF (plateled rich fibrin), is presented. PRF is a second-generation PRP thrombocyte concentrate, which provides the implant dentist with access to growth factors through a simple and up-to-date technology. These growth factors are autologous, non-toxic and non-immunogenic, increasing and accelerating normal bone regeneration pathways.

Periapical radiography is a routine radiographic procedure performed by dentists on a daily basis. It can be taken with two techniques, the paralleling technique (P tech) and the bisecting angle technique (B tech). This systematic review aimed to identify the relevant literature, compare the use of P and B techs across various dental specialties, and determine the most appropriate technique to be used for different purposes in taking periapical radiographs. In January 2023, we searched PubMed, Web of Science, Scopus, and Google Scholar to identify the studies that compared the two radiographic techniques. The search string was: (paralleling AND (“bisecting angle” OR “bisected angle”)). Manual reference tracing was also performed to identify the studies potentially missed. After screening, 26 studies were included for the qualitative review. The 26 included studies were published between 1976 and 2021. Ten of the studies were about general dentistry (dental radiology in general applications), whereas another ten studies were related to endodontics, such as working length estimation. Most studies advocated the use of the P tech for general, endodontics, implantology, and other indications. B tech was advocated for patients with a low palatal height. More future studies are needed to evaluate their performance in different scenarios with standardized equipment and radiographic positioning.

The activity of a dentist reveals itself in numerous aspects, and its regulation is determined by the Deontological Code of the Dental Association, which contains a set of rules that dentists are obliged to follow in the exercise of their profession. The regulation of this activity goes beyond following these precepts because, in the legal relationship that is established whenever an agreement is made with a patient to carry out the treatment deemed appropriate, a series of duties and obligations begin for each party, translated into a reciprocal contract, in which the non-compliance of one of them may result in a legal claim. The objective of this study was to research most court decisions delivered in this century, in Portugal, regarding the activity of dentists when faced with patient claims and to outline a framework that better allows us to understand the regulation of this activity within the scope of the contracts established with them. This includes identifying the patients' sex, the judicial instance, the area of dentistry, the location of the injury, the type of liability, the characterization of the obligation, the basis of responsibility, the alteration of biological assets, and the outcome of the action while also not neglecting the identification of trends and jurisprudential evolutions, should they arise. A survey of judgments from the Portuguese Superior Courts was carried out, which focused on decisions from the Supreme Court of Justice, Court of Appeal of Porto, Court of Appeal of Lisbon, Court of Appeal of Coimbra, Court of Appeal of Guimarães, and Court of Appeal of Évora. To understand the judgments analyzed in this study, a brief approach to various legal concepts and institutions of interest was conducted. A summary characterization of the factual basis of the injured party's claim and the legal framework applied, as well as subsequent decisions by higher courts regarding the activity of dentists, was also elaborated. It was impossible to identify any relationship between the field of dentistry and the characterization of the obligation and the basis of responsibility, nor between the outcomes of the actions and these two parameters mentioned. This is likely due to the small sample size, which, although limited, represented all available published superior court decisions in Portugal related to the proposed topic, and because there were different decisions for similar and identical factual situations due to the various scientific and social conceptions adopted by the courts being susceptible to other interpretations., Competing Interests: The authors report no conflicts of interest in this work., (Copyright© 2024 IOFOS This work is published and licensed by International Organization for Forensic Odonto-Stomatology.)

Artificial intelligence (AI) technology is being used in various fields and its use is increasingly expanding in dentistry. The key aspects of AI include machine learning (ML), deep learning (DL), and neural networks (NNs). The aim of this review is to present an overview of AI, its various aspects, and its application in biomedicine, dentistry, and dental biomaterials focusing on restorative dentistry and prosthodontics. AI-based systems can be a complementary tool in diagnosis and treatment planning, result prediction, and patient-centered care. AI software can be used to detect restorations, prosthetic crowns, periodontal bone loss, and root canal segmentation from the periapical radiographs. The integration of AI, digital imaging, and 3D printing can provide more precise, durable, and patient-oriented outcomes. AI can be also used for the automatic segmentation of panoramic radiographs showing normal anatomy of the oral and maxillofacial area. Recent advancement in AI in medical and dental sciences includes multimodal deep learning fusion, speech data detection, and neuromorphic computing. Hence, AI has helped dentists in diagnosis, planning, and aid in providing high-quality dental treatments in less time., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
