RESUMO
Digital technology has emerged as a transformative tool in dental implantation, profoundly enhancing accuracy and effectiveness across multiple facets, such as diagnosis, preoperative treatment planning, surgical procedures, and restoration delivery. The multiple integration of radiographic data and intraoral data, sometimes with facial scan data or electronic facebow through virtual planning software, enables comprehensive 3-dimensional visualization of the hard and soft tissue and the position of future restoration, resulting in heightened diagnostic precision. In virtual surgery design, the incorporation of both prosthetic arrangement and individual anatomical details enables the virtual execution of critical procedures (e.g., implant placement, extended applications, etc.) through analysis of cross-sectional images and the reconstruction of 3-dimensional surface models. After verification, the utilization of digital technology including templates, navigation, combined techniques, and implant robots achieved seamless transfer of the virtual treatment plan to the actual surgical sites, ultimately leading to enhanced surgical outcomes with highly improved accuracy. In restoration delivery, digital techniques for impression, shade matching, and prosthesis fabrication have advanced, enabling seamless digital data conversion and efficient communication among clinicians and technicians. Compared with clinical medicine, artificial intelligence (AI) technology in dental implantology primarily focuses on diagnosis and prediction. AI-supported preoperative planning and surgery remain in developmental phases, impeded by the complexity of clinical cases and ethical considerations, thereby constraining widespread adoption.

PURPOSE: The purpose of this systematic review and meta-analysis was to compare the influence of fabrication method (conventional, subtractive, and additive procedures) and manufacturing trinomial (technology, printer, and material combination) on the marginal and internal fit of cobaltchromium (Co-Cr) tooth-supported frameworks. MATERIALS AND METHODS: An electronic systematic review was performed in five data bases: MEDLINE/PubMed, Embase, World of Science, Cochrane, and Scopus. Studies that reported the marginal and internal discrepancies of tooth-supported Co-Cr additive manufacturing (AM) frameworks were included. Two authors independently completed the quality assessment of the studies by applying the Joanna Briggs Institute Critical Appraisal Checklist for Quasi-Experimental Studies. A third examiner was consulted to resolve lack of consensus. RESULTS: A total of 31 articles were included and classified based on the evaluation method: manufacturing accuracy, the dual- or triple-scan method, stereomicroscope, optical coordinate measurement machine, microCT, profilometer, and silicone replica. Six subgroups were created: 3D Systems, Bego, Concept Laser, EOS, Kulzer, and Sisma. Due to the heterogeneity and limited data available, only the silicone replica group was considered for meta-analysis. The metaanalysis showed a mean marginal discrepancy of 91.09 µm (I2 = 95%, P < .001) in the conventional group, 77.48 µm (I2 = 99%, P < .001) in the milling group, and 82.92 µm (I2 = 98%, P < .001) in the printing group. Additionally, a mean internal discrepancy of 111.29 µm (I2 = 94%, P < .001) was obtained in the conventional casting group, 121.96 µm (I2 = 100%, P < .001) in the milling group, and 121.25 µm (I2 = 99%, P < .001) in the printing group. CONCLUSIONS: Manufacturing method and selective laser melting (SLM) metal manufacturing trinomial did not impact the marginal and internal discrepancies of Co-Cr frameworks for the fabrication of tooth-supported restorations.

The visual appeal of teeth and smiles significantly influences both how others perceive individuals and their self-image and confidence. The subjective nature of dental esthetics, varying greatly among patients and dental professionals, has made digital smile design tools essential for creating natural and personalized esthetics. Contemporary digital methods and workflows encompass all clinical phases, from diagnosis to the creation of a smile aligned with the patient's facial features, and the completion of the restoratives. Digital technologies not only streamline treatment planning, smile designing, and the creation of restorations but also enable effective and time-efficient collaboration among different dental specialists and dental laboratory technicians, enhancing overall patient care. The use of contemporary digital tools in interdisciplinary esthetic treatments is presented, underscoring the role of high magnification for precision, implant placement, minimal invasiveness, and clinical effectiveness.

OBJECTIVES: Tooth grinding produces a significant amount of aerosol particles. The aim of this study was to quantitatively assess particle contamination produced from tooth grinding with a speed-increasing handpiece across a real-world clinical setting. METHODS: All molar crowns were pretreated into cylinders with a uniform size. A novel computer-assisted numerical control system was used to parametrically study the bur speed: from 20,000 (20 K) to 200 K rpm at 20 K rpm intervals. 5-minute tooth grinding was performed in triplicate at each speed setting. Three online real-time particle counters (ORPC; TR-8301, TongrenCo.) were placed at 3 positions (0.5, 1, and 1.5 m) to evaluate particle production. All experimental instruments were controlled remotely. The data obtained were statistically analyzed using descriptive statistics and non-parametric tests (Scheirer-Ray-Hare and Kruskal-Wallis/ Dunn-Bonferroni tests, p < 0.05). RESULTS: The concentration level of aerosol particles production during the grinding experiment was elevated above the control group for all conditions, and increased with bur speed at any location (the maximum peak, reaching 5.59 × 107 particles/m3, at 200 K and 1 m), with differences between conditions. The effect of speed on the increment of particles across different channels compared to the control group was statistically significant among locations (p < 0.001). CONCLUSIONS: Statistically significant particle contamination was produced using a speed-increasing handpiece, but the contamination level for each experimental condition was reduced to baseline within 30 min, and most particles with a diameter greater than 1üm produced at low speeds (80 K or lower) tended to settle within 1 m. CLINICAL RELEVANCE: Our study suggested that the use of a speed-increasing handpiece below 80 K and 30 min of fallow time may lead to an adequate reduction in the health effects of particle contamination.

INTRODUCTION: A dental technologist is one of the most essential allied dental health professionals and the dental technology curriculum should be comprehensively reviewed on a regular basis. This study aims to compare the only existing Bachelor of Dental Technology (BDT) curriculum in Malaysia with BDT programmes offered by other well-established universities, and map out the similarities and differences, as well as to explore future recommendations and propose a new curriculum framework. MATERIALS AND METHODS: A descriptive analysis was carried out using Laurie Brady's four-stage strategy. First, available curriculum materials were collected from four different institutions' electronic webpage: AIMST (Malaysia), GU (Australia), UO (New Zealand) and CMU (United Kingdom), and then compared based on three key domains: curriculum contents, teaching and learning strategies and assessments. Following that, the similarities and differences between various curricula were identified. Future recommendations and a curriculum framework were then proposed. RESULTS: The core BDT curriculum content is concurred upon by all four universities, with an emphasis on basic sciences, laboratory materials, practical sessions and research projects. However, the credit weightage for each course or module varied across the four institutions, with some offering unique subjects and implementing different teaching methods and assessments. A simple BDT curriculum framework with a proposed syllabus was designed based on the three key domains and future recommendations for curriculum improvement were explored. CONCLUSION: The present study identified several areas for Malaysian BDT curriculum development and improvement. The proposed framework can be a guide for Malaysian dental schools in designing a comprehensive dental technology programme.

Cleft lip and palate is a very common congenital defect in which embryonic facial processes do not achieve the ideal facial formation during their development which can cause malformation. Multiple dentistry specializations, especially oral and maxillofacial, orthodontics, oral rehabilitation and dental aesthetics are required in order to correct lip and oral cavity malformations by this congenital defect with the objective of functional and aesthetics improvement. The clinical case reported show the multidisciplinary approach in a patient with cleft lip and palate implementing an aesthetic and functional dentofacial rehabilitation. The case involves a 27-year-old female patient LCLG, Caucasian, with the presence of unilateral congenital cleft lip and palate on the left side, who started rehabilitative and reparative treatment at 3 months of age. She then started pediatric orthodontic treatment for angle class 3 crossbite correction at 7 years of age. After complete replacement of deciduous to permanent dentition at the age of 11, the patient started orthodontic treatment with a fixed appliance for several years and restorative treatment with composite resin reanatomize the anterior teeth due to agenesis of elements 22 and 25. After a few years when the resin restorations were no longer biologically favorable, an aesthetic rehabilitation treatment with ceramic laminates was planned through smile digital planning soon after completing the orthodontic treatment. This case report demonstrates that high aesthetic, functional and psychological expectations of a patient with congenital defect compromise throughout her life were met through a multidisciplinary dental treatment based on correct diagnosis and digital planning (AU)
A fissura labiopalatal é um defeito congênito muito comum, no qual os processos faciais embrionários não atingem a formação facial ideal durante o seu desenvolvimento, podendo causar malformações. Múltiplas especializações da odontologia, principalmente buco-maxilo-facial, ortodontia, reabilitação oral e estética dental são necessárias para corrigir as malformações labiais e da cavidade oral por esse defeito congênito com o objetivo de melhoria funcional e estética. O caso clínico relatado mostra a abordagem multidisciplinar em um paciente com fissura labiopalatal implementando uma reabilitação dentofacial estética e funcional. O caso envolve uma paciente do sexo feminino, 27 anos, LCLG, branca, com presença de fissura labiopalatal congênita unilateral à esquerda, que iniciou tratamento reabilitador e reparador aos 3 meses de idade. Após a substituição completa da dentição decídua pela permanente aos 11 anos de idade, a paciente iniciou tratamento ortodôntico com aparelho fixo por vários anos, e tratamento restaurador com resina composta para reanatomizar os dentes anteriores devido à agenesia dos elementos 22 e 25. Após alguns anos em que as restaurações em resina não eram mais favoráveis biologicamente, foi planejado um tratamento reabilitador estético com laminados cerâmicos através do planejamento digital do sorriso logo após a finalização do tratamento ortodôntico. Este relato de caso demonstra que as altas expectativas estéticas, funcionais e psicológicas de uma paciente com comprometimento de defeito congênito ao longo de sua vida foram atendidas por meio de um tratamento odontológico multidisciplinar baseado em diagnóstico correto e planejamento digital (AU)

O dissilicato de lítio, se tornou popular para confecção de coroas dentárias devido às suas propriedades biomecânicas e compatibilidade biológica. O sucesso a longo prazo das restaurações depende de diversos fatores, entre eles, a espessura adequada da cerâmica e a ausência de áreas retentivas nos preparos dentais. O presente estudo baseia-se em uma análise exploratória de dados, e teve como objetivo analisar a presença de áreas retentivas nos preparos dentais e as espessuras das coroas totais em dissilicato de lítio, com intuito de identificar as faces do preparo com maior presença de áreas retentivas e as zonas de maior e menor susceptibilidade a fadiga precoce das restaurações. Um total de 100 preparos para coroas totais de molares superiores e inferiores, realizados por cirurgiões-dentistas, foram selecionados aleatoriamente e escaneados através de um scanner de bancada. O design das coroas totais cerâmicas foi realizado através do software Exocad (versão 2.2). Os arquivos em STL foram analisados por inspeção baseada em pontos, utilizando as ferramentas do Exocad. Para análise das espessuras do design da coroa, optou-se por secciona-las virtualmente em 3 cortes transversais e 3 longitudinais. A partir desses cortes realizou-se a mensuração de 54 pontos, após análise 50 pontos obtiveram relevância, esses foram divididos em 11 grupos, que representavam a faces: mesial, distal, vestibular, lingual e oclusal, os pontos foram distribuídos no terço oclusal, terço médio, terço cervical e oclusal das faces citadas, e comparados com a espessura ideal para se obter resistência adequada segundo a literatura. Através das análises estatísticas obteve-se como grupo de maior susceptibilidade a fadiga precoce da restauração o Grupo 3 (terço cervical da parede lingual), com 84,67% das amostras com a espessura inferior ao padrão para este grupo, seguido do Grupo 4 (terço cervical da parede vestibular) com 83,67% das amostras com a espessura inferior ao valor padrão. O Grupo 8 (terço oclusal e médio da parede distal) obteve a maior porcentagem das amostras satisfatórias, 86% obtiveram o valor igual ou acima do padrão, o Grupo 9 (terço oclusal e médio da parede mesial) apresentou 84,50% das amostras com valores iguais ou acima do valor padrão do grupo. Concluiu-se que, o terço cervical é a região com a maior susceptibilidade a fadiga precoce, e o terço oclusal e médio da distal a região com menor susceptibilidade a fadiga precoce. Para a análise dos preparos para as coroas utilizou-se a ferramenta do Exocad, Análise de Retenção, após a seleção do eixo de inserção da restauração, foi possível a visualização através de um gráfico de cor, que varia do azul ao vermelho para as áreas retentivas, como resultado, a face vestibular apresentou 27% dos preparos com necessidade de alívio, sendo a região com menor presença de áreas retentivas, porém a região distal apresentou necessidade de alívio em 40% dos casos, sendo a área com maior presença de retenção. Assim, a face distal dos preparos é a que mais apresentou áreas retentivas e a vestibular a face com menos zonas de retenção (AU)
The lithium disilicate has become popular for the fabrication of dental crowns due to its biomechanical properties and biological compatibility. The long-term success of restorations depends on various factors, including the appropriate thickness of the ceramic and the absence of retentive areas in dental preparations. This study is based on an exploratory data analysis and aims to analyze the presence of retentive areas in dental preparations and the thickness of lithium disilicate full crowns. The goal is to identify the preparation surfaces with a higher presence of retentive areas and the zones with greater and lesser susceptibility to early fatigue of the restorations. A total of 100 preparations for full crowns of upper and lower molars, performed by dentists, were randomly selected and scanned using a benchtop scanner. The design of the ceramic full crowns was carried out using Exocad software (version 2.2). The STL files were analyzed through point-based inspection using Exocad tools. For the analysis of crown design thickness, they were virtually sectioned into 3 transverse and 3 longitudinal cuts. Fifty relevant points were measured, divided into 11 groups representing the surfaces: mesial, distal, vestibular, lingual, and occlusal. These points were distributed in the occlusal, middle, cervical, and occlusal thirds of the mentioned surfaces and compared with the ideal thickness to achieve adequate resistance according to the literature. Through statistical analyses, the group with the highest susceptibility to early fatigue of the restoration was identified as Group 3 (cervical third of the lingual wall), with 84.67% of samples having thickness below the standard for this group. Group 4 (cervical third of the vestibular wall) followed closely, with 83.67% of samples having thickness below the standard. Group 8 (occlusal and middle thirds of the distal wall) showed the highest percentage of satisfactory samples, with 86% achieving or exceeding the standard value. Group 9 (occlusal and middle thirds of the mesial wall) presented 84.50% of samples with values equal to or above the standard for the group. It was concluded that the cervical third is the region with the highest susceptibility to early fatigue, and the occlusal and middle thirds of the distal region have the least susceptibility to early fatigue. For the analysis of crown preparations, the Exocad tool, Retention Analysis, was utilized. After selecting the restoration insertion axis, visualization through a color chart, ranging from blue to red for retentive areas, revealed that the vestibular surface showed 27% of preparations requiring relief, representing the region with the least presence of retentive areas. Conversely, the distal region required relief in 40% of cases, making it the area with the highest retentive presence. Thus, the distal surface of preparations exhibited the most retentive areas, while the vestibular surface had the fewest retention zones.(AU)

BACKGROUND: Digital dental technology (DDT) has progressed and been introduced to Taiwan in the recent years, gradually changing the industry ecology. Many studies have demonstrated that DDT is more accurate and faster than conventional dental technology. However, there is a paucity of research exploring dental technicians' perspectives on digital dental techniques, and their burnout, job satisfaction, and turnover intention. METHODS: This cross-sectional survey with convenience sampling was conducted at the conference venue of the Taiwan Association of Dental Technology to investigate the perspectives of dental technicians. We used the snowballing method in this study; two sampling methods were adopted, a convenience sampling of dental technicians to complete a survey, followed by asking the survey participants of the convenience sample to invite their colleagues to participate in the online survey. The survey questionnaire included questions on demographics, work-related information, acceptance and experiences of dental technicians toward DDT, occupational burnout, job satisfaction, and turnover intention. Regression models were used to determine the predictors of job satisfaction and determinants of turnover intention. RESULTS: In total, 341 valid questionnaires were obtained. Overall, the participants reported long working hours (95.5%), positive score on the DDT acceptance scale, moderate job satisfaction, higher personal burnout, and work burnout, along with lower over-commitment. Among them, 32.9% and 28.2% reported the intention to leave their organization and profession, respectively. The stepwise multiple regression model revealed that higher work burnout decreased job satisfaction, while higher DDT acceptance and position as employer increased job satisfaction. The binary logistic regression models revealed that geographical area of workplace, work burnout, and job satisfaction were significant predictors of turnover intentions. CONCLUSIONS: Many Taiwanese dental technicians reported turnover intentions and higher burnout. With the trend of digitalization in the dental industry, even though most dental technicians had a positive outlook toward DDT, its influence on job satisfaction appears limited. Retaining good and professional talents required of a dental technician is crucial, especially as Taiwan's dental care becomes increasingly specialized. Strategies for improving the work environment and occupational health of dental technicians should thus be the focus of future studies.

Objective: The primary objective of this cross-sectional national study was to investigate the status of digital dental technology (DDT) adoption in Saudi Arabian undergraduate dental education. A secondary objective was to explore the impact of dental schools' funding sources to incorporate digital technologies. Methods: A self-administered questionnaire was distributed to the chairpersons of prosthetic sciences departments of the 27 dental schools in Saudi Arabia. If any department chairman failed to respond to the survey, a designated full-time faculty member was contacted to fill out the form. The participants were asked about the school's sector, DDT implementation in the curriculum, implemented level, their perceptions of the facilitators and challenges for incorporating DDT. Results: Of the 27 dental schools (18 public and 8 private), 26 responded to the questionnaire (response rate: 96.3%). The geographic distribution of the respondent schools was as follows: 12 schools in the central region, 6 in the western region, and 8 in other regions. Seventeen schools secure and preserve patients' records using electronic software, whereas nine schools use paper charts. Seventeen schools (64,4%) implemented DDT in their curricula. The schools that did not incorporate DDT into their undergraduate curricula were due to not being included in the curriculum (78%), lack of expertise (66%), untrained faculty and staff (44%), and cost (33%). Conclusions: This national study showed that digital components still need to be integrated into Saudi Arabian dental schools' curricula and patient care treatment. Additionally, there was no association between funding sources and the DDT implementation into the current curricula. Consequently, Saudi dental schools must emphasize the implementation and utilization of DDT to align with Saudi Vision 2030 for healthcare digitization and to graduate competent dentists in digital dental care.

PURPOSE/OBJECTIVES: To investigate factors associated with predoctoral students' intention to use dental technology in future practice using the theory of planned behavior. METHODS: A comprehensive survey was developed consisting of 29 questions grouped in three main domains: knowledge, perception, and suggestions. After students had completed their digital dentistry didactic courses in 2019, the University of Iowa-College of Dentistry and Dental Clinics D2, D3, and D4 classes completed the survey. The D1 class was excluded because they had not finished their digital dentistry didactic courses. The survey data were tabulated for each class separately to compare trends among classes. Each response was analyzed individually before creating scores for the various subdomains. A linear regression analysis was used to create the final model for the outcome variable (intention to use technology). RESULTS: The response rate was 95% (n = 232). The mean age of participants was 25.7 years (SD = 2.7). There were significant differences between the classes in their knowledge (p < 0.0001), perceived quality of training (p < 0.0001), and all perceptions related to digital dentistry. Controlling for significant covariates among higher level students, there were significant associations between intention to use dental technology and greater knowledge scores (p = 0.05), attitude (p < 0.0001), subjective social norms (p = 0.02), and perceived control on the future use of technology (p < 0.0001). CONCLUSIONS: Students may be motivated to use digital technology when they have good knowledge, feel that others are using it or endorsing its use, and perceive that they have control in their future practice.

Dentistry, as a branch of medicine, has undergone continuous evolution over time. The scientific world has focused its attention on the development of new methods and materials with improved properties that meet the needs of patients. For this purpose, the replacement of so-called "passive" dental materials that do not interact with the oral environment with "smart/intelligent" materials that have the capability to change their shape, color, or size in response to an externally stimulus, such as the temperature, pH, light, moisture, stress, electric or magnetic fields, and chemical compounds, has received much attention in recent years. A strong trend in dental applications is to apply nanotechnology and smart nanomaterials such as nanoclays, nanofibers, nanocomposites, nanobubbles, nanocapsules, solid-lipid nanoparticles, nanospheres, metallic nanoparticles, nanotubes, and nanocrystals. Among the nanomaterials, the smart nanoparticles present several advantages compared to other materials, creating the possibility to use them in various dental applications, including preventive dentistry, endodontics, restoration, and periodontal diseases. This review is focused on the recent developments and dental applications (drug delivery systems and restoration materials) of smart nanoparticles.

Organic contaminants significantly limit the bioactivity of titanium implants, resulting in the degradation known as the ageing of titanium. To reactivate the surfaces, they can be photofunctionalized, i.e., irradiated with C-range ultraviolet (UVC) light. This descriptive in vitro study compares the effectiveness of novel light-emitting diode (LED) technology to remove contaminant hydrocarbons from three different commercially available titanium dental implants: THD, TiUnite, and SLA. The surface topography and morphology were characterized by scanning electron microscopy (SEM). The chemical compositions were analyzed by X-ray photoelectron spectroscopy (XPS), before and after the lighting treatment, by a pair of closely placed UVC (λ = 278 nm) and LED devices for 24 h. SEM analysis showed morphological differences at the macro- and micro-scopic level. XPS analysis showed a remarkable reduction in the carbon contents after the UVC treatment: from 25.6 to 19.5 C at. % (carbon atomic concentration) in the THD; from 30.2 to 20.2 C at. % in the TiUnite; from 26.1 to 19.2 C at. % in the SLA surface. Simultaneously, the concentration of oxygen and titanium increased. Therefore, LED-based UVC irradiation decontaminated titanium surfaces and improved the chemical features of them, regardless of the kind of surface.

Objetivos: Mensurar los niveles de radiación de fuga y dispersión emanada a través de los blindajes y estructuras plomadas del tubo de rayos X de la unidad dental portátil NOMAD, controlando la retrodispersión con el uso del escudo protector de acrílico plomado adaptado en el extremo final del tubo localizador plomado. Se midieron las tasas de exposición dispersadas mediante un detector tipo Geiger-Müller y una cámara de ionización con respuesta en el rango de energías aportadas en diagnóstico por imágenes para la medición de la exposición directa y determinación posterior de las dosis. Se utilizó un fantomas diseñado para diagnóstico odontológico, sopesando la radiación en diferentes angulaciones de operación del equipo NOMAD, simulando los gestos posturales de odontólogos, radiólogos y sujetos a identificar. Se controlaron las tasas de exposición para determinar los valores de las dosis aportadas en las zonas significativas corporales más radiosensibles del operador del equipo. Se obtuvo como resultado que la retrodispersión en el cristalino del ojo del operador fue significativamente menor cuando el fantomas estaba acostado, mientras que a nivel de gónadas resultó más baja con el cuerpo sentado. La tasa de dosis máxima de radiación dispersa que impactó en los operadores fue de 350.8 micro Sieverts por hora (uSv/h) en la zona de gónadas, por cada radiografía tomada sin el uso del delantal de goma plomada, reduciéndose a 4.38 micro Sieverts por hora (uSv/h) al utilizarlo (AU)

¿Cuándo fue que nos despertamos y nos dimos cuenta de que estábamos en una escena de película? Algo impensado para nosotros, un aislamiento, nos hizo sentir más que nunca que somos seres sociales. ¿Y qué ocurrió con la educación en este contexto? El modo en que el ámbito universitario atravesó la pandemia y la inclusión de la tecnología en la enseñanza odontológica invitan a reflexionar sobre los cambios que tuvieron lugar y que llegaron para quedarse (AU)
That moment when we found ourselves in the middle of a movie scene. Something unexpected for us, the isolation showed us the importance for human beings to socialise. The changes experienced in education during the lockdown in 2020 with the inclusion of technology like internet in dental education, invites us to reflect about those changes and how they will affect dental education in the future (AU)
