The utilization of computer-assisted design and computer-assisted manufacturing (CAD/CAM) techniques in the creation of complete dentures (CDs) has piqued the interest of many people. This article seeks to provide a comprehensive, critical, and objective analysis of the current knowledge of CDs and related technology. The aim of this study is to assess existing literature concerning 3D-printed complete dentures, covering aspects like innovative biomaterials, manufacturing methods and processes, workflow, and clinical effectiveness. The design of the current study included an initial review of 172 titles, an appraisal of abstracts, and finally a selection of articles for rigorous textual analysis. Inconsistencies discovered throughout the selection process were amicably resolved through discourse, culminating in the identification of 65 items. The publications retrieved from a thorough search of the PubMed, Scopus, and Embase databases spanned the years 1994 to 2023. Contemporary digital technology provides evident advantages, but its successful incorporation necessitates meticulous preparation. In the realm of dental healthcare, the digital workflow showcases versatility and a range of applications.

The advent of zirconia ceramics with excellent mechanical, biomechanical, and optical properties has made them attractive metal-free substitutes for titanium implants. Both animal and human studies have documented shortcomings with titanium implants. A mapping review of the current literature on three iterations of zirconia implant designs has been challenging due to heterogeneous success data and limited follow-up. Zirconia implants hold promise for a new generation of dental implants, but technical developments are needed for design and material enhancements that will need to be validated by long-term rigorous studies.

(1) Background: In this qualitative study, we investigated the implementation of an art-based observation workshop as a tool to improve visualization and interpretation skills in a cohort of first-year dental students (N = 109) in a dental anatomy course. (2) Methods: The art workshop was held once for a total of 60 min in the pre-clinical simulation laboratory, which is the regular teaching setting for the dental anatomy course. Visualization and interpretation skills were assessed before (pre-test) and after the art-based observation workshop (post-test). The pre- and post-tests contained five images that guided students to describe dental anatomy images. The pre- and post-test had different but similar images. Dental students accessed the pre- and post-tests on CANVAS and recorded their answers. After that, the audio recording files were analyzed and compared to determine the frequency of use of dental anatomy-specific nomenclature while answering the pre- and post-test. (3) Results: Our results demonstrate that students used dental anatomy-specific nomenclature more frequently after the intervention. (4) Conclusions: we have concluded that students’ use of dental anatomy nomenclature in the first-year dental anatomy curriculum is enhanced following an art-based intervention in a regular dental simulation laboratory.

The purpose of this study is to report a case of idiopathic osteosclerosis of the mandible and to discuss the differential diagnosis of this lesion. A 17-year-old female was referred to the University Hospital of Geneva by her orthodontist following the fortuitous finding of a radio-opaque lesion in the right posterior mandible at the apex of tooth 44. Intraoral clinical examination revealed no abnormalities of the oral mucosa. Tooth 44 was asymptomatic and reacted positively to the sensitivity test. The orthopantomogram revealed a well-defined unilocular radiodense lesion, surrounded by a thin radiolucent border, measuring 10 × 33 mm, located in the IV quadrant, related to the apex of tooth 44. Differential diagnoses mainly included cementoblastoma, focal cemento-osseous dysplasia, ossifying fibroma, condensing osteitis and idiopathic osteosclerosis. The biopsy material allowed a diagnosis of idiopathic osteosclerosis. The proposed treatment was therefore a “wait and see” approach. After 2 years of follow-up, the patient was asymptomatic, and healing was complete without any neurosensory complications. Our case underlines the differential diagnosis complexity of radio-opaque lesions associated with teeth.

Skeletal Class II is a common malocclusion affecting the Caucasian population and characterized, in most cases, by a convex profile and mandibular retrusion. Therefore, the treatment plan often requires the use of functional appliances to promote mandibular advancement. In particular, the Herbst appliance is recommended because of its efficiency and minimal need for compliance. However, in addition to skeletal favorable effects, undesired dental compensations could prematurely reduce the overjet needed for a proper orthopedic outcome. The combination of this appliance with skeletal anchorage and elastic ligatures in the lower or both, in the upper and the lower arch, enables effective control of unfavorable tooth movements, improving the therapeutic potential of such a treatment. These improvements have significantly shifted the main focus on facial aesthetics rather than dental occlusion, with the creation of innovative treatment protocols and a new diagnostic approach to Class II malocclusion.
骨骼Ⅱ类是影响白种人的一种常见错颌畸形，大多数情况下，其特征是轮廓外凸和下颌后缩。因此，治疗方案通常需要使用功能性矫治器来促进下颌前突。特别推荐使用赫氏矫治器，因为它效率高，对依从性的要求最低。然而，除了对骨骼有利的效果外，不希望出现的牙齿代偿也会过早地减少矫形所需的上颌前突。将这种矫治器与下牙弓或上牙弓和下牙弓的骨骼固定器和弹性结扎器结合使用，可以有效控制不利的牙齿移动，提高这种治疗方法的治疗潜力。这些改进极大地改变了人们对面部美学而非牙齿咬合的关注，创造出了创新的治疗方案和 II 类错牙合畸形的新诊断方法。

Periodontitis is a common non-communicable inflammatory disease that leads to the destruction of periodontal tissues and tooth loss. Initiated by the plaque biofilm, there is a strong innate immune response with an abundance of neutrophils in the periodontium of affected individuals. Previous reports have shown that the intracellular concentration of glutathione in peripheral blood neutrophils from periodontitis patients and the chemotactic ability of these cells are compromised. Furthermore, other studies have described that in oxidative stress conditions neutrophil chemotaxis is aberrant and causes the glutathionylation of F-actin, a key player in chemotaxis. In this study, the effects of glutathione-modulating compounds were assessed in neutrophils isolated from healthy donors, showing that the perturbation of glutathione homeostasis decreases the chemotaxis of neutrophils. Following this, the intracellular glutathione status and chemotactic ability of neutrophils isolated from periodontitis patients was compared to that of age- and sex-matched controls. A decrease in glutathione and chemotactic ability were confirmed. Finally, the proteome of these neutrophils was explored, demonstrating a change in the abundance of proteins involved in glutathione homeostasis. Together these data suggest that peripheral blood neutrophils from periodontitis patients are compromised in their ability to cope with oxidative stress and move.

Forensic dentistry is still an emerging field in Pakistan. The lack of scientific literature on the topic may lead to difficulties in situations where age estimation has a significant part such as in criminal and civil litigation. In mass disasters such as earthquakes and accidents, the correct investigation of the chronological age can be less troublesome if population-specific evidence is available. This is the rationale that justifies dedicated dental age estimation studies. This cross-sectional study aimed to test the time efficiency, validity and applicability of four dental age estimation methods: two invasive (Bang and Ramm and Lamendin) and two non-invasive (Kvaal and Cameriere) in an adult Pakistani population. A total of 37 teeth collected from a dental hospital in Islamabad, Pakistan, were used. Teeth included the central and lateral incisors, canines, and first and second premolars of males and females. Results were calculated using a Microsoft Office 2007 excel spreadsheet. Overall, Kvaal’s method mean absolute error between chronological and estimated ages (MAE: 12.33) showed the highest variation and Bang and Ramm showed more accurate results in comparison with other methods (MAE: 4.80). It was both time-efficient and practical to use. It can be stated that these were preliminary cross-sectional outcomes and that studies with larger samples are necessary.
在巴基斯坦，法医牙科仍是一个新兴领域。由于缺乏相关的科学文献，在刑事和民事诉讼等对年龄估计有重要影响的情况下，可能会遇到困难。在地震和事故等大规模灾害中，如果有特定人群的证据，对年代年龄的正确调查就不会那么麻烦。这就是专门进行牙科年龄估计研究的理由。这项横断面研究旨在测试四种牙科年龄估计方法的时间效率、有效性和适用性：两种侵入性方法（Bang 和 Ramm 以及 Lamendin）和两种非侵入性方法（Kvaal 和 Cameriere）。我们使用了从巴基斯坦伊斯兰堡一家牙科医院收集的 37 颗牙齿。牙齿包括男性和女性的中切牙、侧切牙、犬齿、第一和第二前臼齿。结果使用 Microsoft Office 2007 excel 电子表格进行计算。总体而言，Kvaal 法的年代年龄与估计年龄之间的平均绝对误差（MAE：12.33）显示出最大的差异，而 Bang 和 Ramm 法与其他方法相比显示出更精确的结果（MAE：4.80）。这种方法既省时又实用。可以说，这些只是初步的横断面结果，有必要对更大的样本进行研究。

Healthcare organisations around the world have embraced the valuable role that patient experience plays in the improvement of health care delivery. Engaging with patients is a vital component of understanding how to deliver safe, high-quality, respectful health care that is person-centred and efficient. In oral health services, patient experience is historically predominantly reported as challenging, which is most commonly associated with past traumatic experience with poor oral health treatment. Additionally, the high out-of-pocket costs associated with oral health treatment can mean that people disengage with these services, thereby worsening their oral health conditions. Consequently, oral health has an enormous task to reduce the negative perceptions and experiences. This demands innovative and subtle ways to navigate and address patient and service challenges. Exploring and acknowledging the myriad of historical challenges that exist for oral health patients and utilising these experiences to support change will ensure person-centred improvements are designed and implemented. Therefore, this perspective paper defines patient experience and proposes how oral health patient experience can be improved using the concept of meaningful engagement with a focus on the Australian context. We identified two important concepts that impact oral health patient experience and explored how these concepts may play a role in improving oral health services through improved patient experience. The first concept is person, patient, and user which focusses on general patient experience journey in a general health care setting. The second concept is preservice, current service, and post service which relates to an oral health patient’s experience journey in an oral health service setting. Our findings suggest that the practitioner–patient relationship and use of technology are central to patient engagement to improve patient experience.

We investigated the effects of lithium disilicate ceramic thickness and translucency on the degree of polymerization of light-cured resin cement using the measure of hardness. Lithium disilicate specimens of three translucencies (low, medium and high) were prepared to four thicknesses (0.5, 1.0, 2.0 and 3.0 mm). A light-cured resin cement was cured through each of the ceramic specimens using a handheld curing light for 50 s. A 3D printed jig was used to achieve a uniform thickness of the resin cement. Directly cured resin cement was used as the control. Hardness was measured using nano-indentation to determine the degree of polymerization of the resin cement. Two-way ANOVA and Tukey post hoc tests were used to evaluate interaction between translucency and thickness. Hardness values from control specimens were assessed using the two-tailed t-test with the Bonferroni approach. The translucency of the specimens significantly influenced the hardness (p < 0.001), where a negative linear relationship between cement hardness and ceramic thickness was present for low translucency and high translucency. However, at a 0.5 mm thickness, all specimens showed similar hardness regardless of the translucency. The translucency of ceramics affected the hardness, and hence polymerization, of light-cure resin cement. However, the effect of increased thickness was a more significant factor.
