Specifically, maintaining a prolonged sitting position is considered to be associated with an increased risk of musculoskeletal disorders in the back, neck, shoulders, arms, hands, hips, knees and legs. The purpose of this study is to generate data, which can be used to support decisions on improving the health of dental technicians, whose basic activity is carried out in a sitting position at the work table, in order to improve the quality of life. Implementation of ergonomic measures, in the area where professional activities directly affect the physical and mental health of the employee, is of great importance.

In general, the treatment of dentin hyperesthesia can be performed either at home or in the dentist’s office. The therapeutic approach aims at the use of products, which decrease the excitability of pulp nociceptors or reduce the permeability of the dentin canals. The purpose of this study is to compare the efficiency in the treatment of dentin hyperesthesia of a product containing potassium nitrate, compared to another product using Recaldent™ Technology. The results of this study indicated a significant decrease in pain sensitivity both after application of the product using Recaldent™ Technology and after the product containing potassium nitrate, the results being slightly in favour of the first product.

The infectious risk in the dental practice, including in the orthodontic practice, represents a real danger for both the medical team (orthodontic specialist, dental nurse and dental technician), but also for the patient. But, dental orthodontics and dentofacial orthopedics is a specialty in the field of dentistry with a special content and a special instruments and, therefore, by conducting this study, even if it is only preliminary, we set out to highlight a succession of concepts, the objective being to familiarize the specialists in orthodontics and dentofacial orthopedics with certain rules of theoretical and practical character, which aim to prevent and combat the infectious risk in orthodontic practice.

The restoration of a proximal wall depends on several factors, the conformation system playing one of the most important parts of the working protocol. The vertical, transversal and sagittal adaptation of the matrix band implies the use of one or two wedges and of a sectional matrix device (usually with a ring shape) with tines. The size, configuration and the material the tines are made of determine most of the quality of the adaption and stabilization of the matrix band. Even if these standardized tines have various designs and variable flexibility, a truly efficient tine should have a customized configuration which can be obtained after taking the impression of the initial proximal wall. The clinical situations that allow the customization of the standard tines imply proximal caries that have not interrupted the proximal wall or that have interrupted it less than one third of the transversal distance.

Several methods and materials are used in modern restorative dentistry for anterior dental lesions treatment. The desired aesthetic outcome can be obtained only with the correct treatment method correlated to case particularities. Sometimes, subjective and unrealistic approaches lead immediately or in time to undesirable dental restorations. The aim of the present paper is to evaluate the statistic distribution of aesthetic anterior dysfunctions detected on 425 patients from both genders that had restorative treatment during a period of 10 years. For each patient, there has been conducted an initial clinical examination and a photographic documentation was made. Also, each patient was asked to submit a questionnaire regarding his dental history. The results of the study represented the foundation for the discussions regarding the causes that led to aesthetic dysfunctions. The conclusions indicated that all errors that conducted to an initial failure of treatment are only connected with the medical decisions made by the dentist.

Introduction: Esthetic dentistry aims to create a harmonious smile that is well integrated with the facial architecture of the patient. A good understanding of the patient’s esthetic perception is important when designing a smile. Materials and methods: 106 subjects, 51 patients 54 dental students took part in the study. Each subject was asked to evaluate 10 pictures showing frontal aspect of real cases. They were asked to rate the aesthetics of the clinical cases on a scale from 1 to 5. An open question was associated with each picture, where the subjects were asked to describe what they like and what they do not like about the picture. Results and discussions: The overall mean esthetic rating of dental students was 2,68, while the laypersons’ rating was 2,98. Crowded teeth are more often criticized by patients, while dental students consider that slight crowding give a more natural appearance and individualize the teeth. The presence of diastema is observed by dental students even when it is discrete. The discrepancy between maxillary and mandibular dental midline is more easily observed by dental students. Discolored teeth lead to low aesthetic scores for both groups of subjects. Dental students gave lower esthetic scores to restorations with uniform colour, while laypersons appreciate white restorations. The limited height of papillae is considered unattractive by dental students, while laypersons hardly notice this aspect. Conclusions: This study showed several differences in the aesthetic perception of dental students and laypersons. Students were generally more critical and gave lower scores than laypersons. They also observed and criticized more aspects regarding the smile.

A good outcome of an occlusal appliance requires a well-adapted device, both in terms of occlusal relations and internal fit, which helps achieve patient comfort and compliance. Digital technology had led to the manufacturing of night guards that display a better accuracy and properties of the resin, ease of fabrication in terms of time and materials and the possibility of duplication. This technical report describes the clinical and laboratory steps that need to be followed to produce an occlusal appliance in a fully digital protocol. Intraoral scans were acquired, as well as digital occlusal records. A virtual 3D dental device was designed using a CAD software, which was later manufactured via 3D printing technology. The occlusal appliance displayed a good internal fit and enhanced properties of the resin. Minimal occlusal adjustments were required to secure functional guidance during protrusive and lateral movements of the mandible.

Introduction. Most patients over 40 years old who present for specific treatments in the dental offices have at least one general condition. Specialized research has shown that atherosclerosis is more common in patients with periodontal disease, which suggests that periodontal and cardiovascular disease may have similar causes. Purpose. Given the close connection between the two conditions, we have tried to draw the attention of patients to the importance of the prophylactic maneuvers performed by him or by specialized personnel and we also want to emphasize the importance of the dental hygienist in this process. Material and method. In order to carry out this study, a questionnaire with predetermined answers was used, applied to 57 patients with ischemic cardiomyopathy and who presented for specialized treatments in dental offices. Results and discussions. The answers really reflect how the patients understood the connection between the two conditions and how they perform the oral and dental hygiene. Conclusions. Given that many of the respondents do not perform the hygiene procedures correctly or incompletely, there is a need for a medical staff to discuss with patients to educate them on the importance and the way of hygiene and to perform the oral and dental hygiene procedures, in short the dental hygienist.

Data on the functional three-dimensional positioning of the future restoration are important for planning a prosthetic guided insertion of the dental implants. Errors can occur in the digital and analogous process of analysis, design and production of the surgical guides, possibilities of minimizing them being vital for obtaining a predictable surgical and prosthetic process.
