Moisei Schwartz: A military surgeon, educator, and researcher

The personnel of the Department of Dentistry (after 1942, the Department of Maxillofacial Surgery and Dentistry) of the Military Medical Academy named after S.M. Kirov made major contributions to the advancement of dentistry and maxillofacial surgery in Russia. This essay focuses on the professional life of Associate Professor Moisei Schwartz, Major of the Medical Service, whose research significantly contributed to experimental dentistry and periodontology. The essay uses the data presented in Russian literature on dentistry and maxillofacial surgery, as well as the recollections of dentists who knew Moisei Schwartz personally: V.P. Zabelin, Colonel of the Medical Service, and Associate Professor V.V. Fiolkovsky, Colonel of the Medical Service. Associate Professor Moisei Schwartz, Major of the Medical Service, performed several studies of the functional properties of jaw vessels, primarily mandibular vessels. He was the first to use the Kravkov–Pisemsky technique in dentistry to assess the effect of biogenic amines on isolated jaw vessels. His comparative studies of ear and jaw vessels in dogs using this technique revealed that jaw vessels are hypersensitive to acetylcholine, histamine, and adrenaline. In 1936, Moisei Schwartz developed an experimental periodontitis model using chronic irritation (ligation) of the inferior alveolar nerve in dogs. Moisei Schwartz fought in the Soviet-Finnish War of 1939–1940, as well as the World War II (1941–1945). Moisei Schwartz was a prominent scientist and experienced doctor with good manual skills, including surgical care in maxillofacial wounds. Moreover, he was a passionate researcher and educator. His contributions to experimental dentistry and periodontology are impossible to exaggerate.

Dental anxiety is a prevalent issue affecting patients and dental healthcare providers alike, leading to avoidance of treatment and poor oral health outcomes. This study investigates dental anxiety management techniques and their effectiveness in promoting patient comfort, improving oral behavior, and increasing satisfaction during dental care. The research was conducted in Davao City, Philippines, utilizing a qualitative, descriptive phenomenological approach through in-depth interviews with eight participants who experienced dental anxiety. Key findings reveal that dental anxiety stems from unfamiliarity with procedures, negative experiences, and anticipation of pain. Patients reported heightened anxiety due to the sight and sound of dental tools and past negative encounters, often leading to long-term avoidance of care. Effective management strategies, such as deep breathing and distraction techniques, significantly improved patient satisfaction and oral health behavior, fostering better engagement with dental care. The study underscores the importance of patient-centered communication and personalized care in addressing dental anxiety, calling for enhanced integration of mental health considerations in dental practices.

Cytotoxicity and Microbiological Properties of Ceramic CAD/CAM Materials Subjected to Surface Treatment with Nanometric Copper Layer

The aim of this study is to present the characteristics and a comparison of four different commercial materials dedicated to the CAD/CAM technique in dentistry, all of which can be classified as ceramic materials. Its purpose is also to evaluate the impact of surface treatment on the cytotoxicity and microbiological properties of the materials. The CAD/CAM technique has a perpetually growing role in modern reconstructive dentistry. It requires a material’s possession of peculiar characteristics, such as mechanical resistance, durability, functionality (similar to natural tissues), good aesthetics and biocompatibility. To critically evaluate a biomaterial, both manufacturer claims and in vitro tests should be considered. Further steps of evaluation may include animal tests and clinical trials. There are certain attributes of biomaterials that may be modified by surface treatment that can be crucial to the clinical success of the material. The evaluated materials were Vita Suprinity (VITA-Zahnfabrik, Germany), Vita Mark II (VITA-Zahnfabrik, Germany), Celtra Duo (Dentsply Sirona, USA) and Empress Cad (Ivoclar Vivadent, Liechtenstein). They are available in the form of prefabricated blocks of various diameters and are popular among operators performing clinical procedures using CAD/CAM. Standardized blocks of each material were prepared. Half of them had their surface polished. Further, half of all the samples were covered by a nano-copper layer. The samples were evaluated for cytotoxicity, presented on a 0–4 scale, adhesion susceptibility and potential of forming a biofilm on their surface. Physicochemical properties such as the water contact angle (WCA) were evaluated for the tested materials. The influence of copper coating on cytotoxicity cannot be unequivocally stated or denied. Surface polishing did not affect the materials’ cytotoxicity, but it increased the WCA of all materials and, therefore, their hydrophobicity. Different degrees of adhesion ability and biofilm formation were dependent on the species of microorganisms and properties of the dental materials.

Long-term success of inlay and onlay procedures in dental repairs

Inlays and onlays are vital restorative techniques in dentistry, offering a conservative alternative to full crowns while preserving more of the natural tooth structure. These restorations, typically made from ceramic or composite resin materials, provide both aesthetic and functional benefits and are increasingly favored for their durability and longevity. In contrast to direct restorations, inlays and onlays are fabricated outside the mouth, allowing for greater precision and a more customized fit. The clinical success of these restorations largely depends on factors such as material choice, bonding technique, and patient-related variables like oral hygiene and habits. Ceramic materials are particularly noted for their resistance to wear and their ability to closely mimic the natural appearance of teeth, making them an attractive option for both patients and clinicians. Composite resins, while slightly less durable, offer a cost-effective alternative with satisfactory long-term results. Proper bonding techniques and high-quality materials are essential for ensuring the durability of inlays and onlays, with many restorations lasting over a decade. Patient-related factors also play a significant role in the success of inlays and onlays. Effective oral hygiene, regular dental check-ups, and the avoidance of habits like bruxism are essential for maintaining the integrity of these restorations over time. Despite the challenges and technical demands associated with their placement, inlays and onlays are highly successful when properly executed, offering patients a durable, aesthetically pleasing solution for dental repairs. The discussion of this review focuses on the critical elements that influence the long-term success of inlays and onlays, including material selection, clinical technique, and patient management, highlighting their effectiveness as a restorative option in modern dentistry.

Bruxismo del sueño en el paciente infantil: revisión narrativa de la literatura.

Introduction: Sleep bruxism is a parafunctional activity in which clenching and/or grinding of teeth occurs in both the paediatric and adult population. Objective: To gather the most current knowledge available on the causes, diagnosis and treatment of sleep bruxism in children in order to facilitate the dentist and/or paediatric dentist's identification and appropriate management in daily clinical practice. Material and methods: An electronic bibliographic search of articles published in English between 1986 and 2023 on sleep bruxism in children under 14 years of age was carried out. Thirty-six articles were selected. Results: The prevalence of sleep bruxism in children ranges from 5 to 46%. Of multifactorial aetiology, its clinical manifestations are both intraoral and extraoral. Diagnosis in most cases is not easy and must be made by assessing not only its consequences but also the aetiological elements involved. Comprehensive treatment always requires an early and multidisciplinary approach combining psychological and dental techniques. The available evidence does not support the use of rigid splints in children. Conclusion: Current knowledge on sleep bruxism in children aims to focus on early diagnosis and aetiological treatment, but further studies are still needed to achieve a standardised and protocolised early diagnosis that will help clinicians' decision-making and improve the patient's quality of life in the short, medium and long term.

SWEET DREAMS, BRIGHT SMILES: ORAL SEDATION FOR KIDS

Oral sedation plays a pivotal role in pediatric dentistry, providing an effective approach to manage anxiety and behavioral challenges in young patients. The fear and apprehension associated with dental visits can lead to non-cooperation, making it challenging for dental practitioners to deliver proper care. Behavior management techniques in pediatric dentistry have evolved over the years to create a child-friendly and comfortable environment in the dental office. One approach that has gained popularity is the use of oral sedatives to help alleviate childrens anxiety and facilitate cooperative behavior during dental treatments. Oral sedation involves administering safe and carefully dosed medications to induce a state of relaxation, without the need for general anesthesia. Utilizing oral sedatives in pediatric dentistry not only facilitates the dental procedure but also enhances the overall experience for both the child and the dental team.

Intraoral scanner-based virtual facebow transferring: A chairside dental technique.

Accurately mounting dental casts on an articulator is an essential step in prosthetic treatments. In digital dentistry, virtual articulator mounting procedures rely on virtual facebow records. However, virtual facebow records usually require devices like face scanners or jaw motion tracking systems that are not commonly available in most dental practices. The present technique report describes a straightforward intraoral scanner-based virtual facebow transfer approach. In this technique, a reference facebow joint support was first scanned and aligned with a virtual articulator. Then, a patient's facebow joint support and bite fork assembly were scanned chairside with an intraoral scanner and aligned with the virtual articulator by matching common features with the reference facebow joint support. After aligning the patient's intraoral scans with the patient's bite fork scan that was already superimposed on the virtual articulator, a virtual mounting process was achieved. Once the corresponding reference facebow joint supports have been generated, this technique can be easily implemented with most facebow systems and be seamlessly integrated into daily clinical practice as only an intraoral scanner and a conventional facebow were required.

Effectiveness of Different Behavior Management Techniques in Pediatric Dentistry.

Pediatric dentistry necessitates efficient behavior management methods to ensure successful treatment outcomes and positive experiences for young patients. This research aims to evaluate the comparative effectiveness of "Tell-Show-Do (TSD)", positive reinforcement, nitrous oxide sedation, and pharmacological sedation in pediatric dental practice. A retrospective analysis was conducted on pediatric patients aged 3-12 years who underwent dental treatment at a designated dental center over a 1-year period. Patients were categorized based on the behavior management method utilized: TSD, positive reinforcement, nitrous oxide sedation, or pharmacological sedation. Treatment success rates and patient cooperation levels were evaluated for each method. Positive reinforcement and TSD demonstrated the highest treatment success rates (85% and 80%, respectively) and patient cooperation levels (90% and 85%, respectively). Nitrous oxide sedation exhibited moderate effectiveness with a treatment success rate of 70% and a patient cooperation level of 75%. Pharmacological sedation had the lowest treatment success rate (60%) and patient cooperation level (65%). Statistical analysis revealed significant differences in treatment success rates (P < 0.05) and patient cooperation levels (P < 0.05) among the behavior management methods. Positive reinforcement and TSD emerge as highly efficient behavior management methods in pediatric dentistry, promoting high treatment success rates and patient cooperation levels. Nitrous oxide sedation offers a valuable adjunct for managing anxiety and enhancing patient comfort. Pharmacological sedation, while efficient in certain cases, should be used judiciously due to associated risks.

The present technique describes a way of transferring the horizon orientation of the NHP into a computer-aided design software program with a recently developed NHP recording and transferring device (Patent No. ZL202110992198.6 China). The device can record NHP using 5 marked points which can be visualized radiographically.

Dog-Assisted Therapy (DAT) for the management of anxiety during paediatric dental care. A scoping review.

Distraction techniques in paediatric dentistry can be effective in decreasing the child's attention span from an unpleasant or stressful procedure. Distraction is achieved through imagination, audio, and/or visual stimuli. It has been shown that the accompaniment and participation of animals or pets, specifically dogs (Dog-Assisted Therapy or DAT), during medical, oral, and therapeutic activities can improve the physical and mental health of patients, especially children. However, there is limited information available regarding the impact of incorporating a certified therapy dog into the paediatric dental environment as a distraction strategy to alleviate anxiety levels during dental procedures. This scoping review aimed to identify and review published articles concerning the use of DAT in paediatric dentistry. The article discusses indications, benefits, and potential risks to human health and safety in clinical settings. Eligible sources encompass clinical trials, observational studies, and narrative reviews written in either English or Spanish and published over the last two decades, sourced from four electronic databases. Ultimately, seven pertinent studies were included in the review. DAT presents itself as a promising alternative in managing anxiety and stress among children during dental visits. The integration of a therapy dog and its handler into the paediatric oral care team should be thoughtfully considered by clinicians as a means to enhance the comfort and compliance of apprehensive patients.

Alternative Augmentative Communication in paediatric dentistry: a mighty tool to amplify mother tongue's power.

The role of a child's mother tongue in shaping his/her identity and emotional development is crucial. In the context of paediatric dentistry, this principle should always be reminded. The child's right to effective communication, even when a language barrier exists, is a fundamental principle, as recently stated in the 'Rights from the Start' rights fact sheet. Preserving a child's native language in the dental setting, especially in the context of an increasingly diverse society with a significant number of refugee children, is essential. Augmentative and Alternative Communication (AAC) strategies can assist in bridging language gaps and improving treatment outcomes, blending with the traditional approaches used in paediatric dentistry. The article promotes flexibility, innovation, and empathy in paediatric dentistry to provide optimal care and ensure that every child's rights are respected. • The relationship with one's mother language plays a central role in children's growth and in the relationship they can develop with the world, "motherised" by the words of the caregiver. • The interaction between immigrant children from different linguistic and cultural backgrounds and dentists providing their care requires the integration of traditional paediatric dental techniques with AAC strategies that can compensate for deficient oral communication. • Dentists treating immigrant children should follow the suggestions proposed in this article to establish the best and most tailored paediatric setting for the child's specific needs.
