Dentists, members of the French Resistance movement during the World War II

The Resistance was a reaffirmation of France's independence and individuality, as well as a struggle to regain freedom and, above all, national integrity. In fact, many historians appreciate that the French Resistance could have achieved more if it had been more effectively integrated into Allied plans and strategies. Thus, in this material we tried to present some short biographies of dentists who worked in the French Resistance against the German occupation troops, some of them even paying with their lives for the courage they showed

ERGONOMIC CONCEPTS IN DENTAL MEDICINE

Dental medicine is an extremely complex medical field, comprising several specialties (orthodontics and dentofacial orthopedics, prosthodontics, dental surgery, endodontics etc.), which in most cases also require the assistance of a dental nurse. Purpose. In this paper, we have tried to present a number of very interesting ergonomic aspects in the dental office, which aim at simplifying work at this level. Material and method. This study was conducted between May and July 2018 using a questionaire applied to a number of 69 dental practitioners from Bucharest. Results and discussions. Results obtained in this study give us an image about how current dental practitioners understand ergonomics in daily practice. Conlclusions. All the aspects discussed in this study have an important role in the ergonomy of daily activity of a dental office. More important is that the majority of dentists involved in the stuty understand and apply the ergonomic concepts underlined by this study

THEORETICAL AND PRACTICAL ASPECTS IN THE MAINTENANCE PROCESSES OF CEMENT RETAINED IMPLANT SUPPORTED FIXED RESTORATIONS

The lifespan of a fixed implant supported restoration is influenced by several factors: the medical team's experience, the superior technical and material endowment, the experience of the dental laboratory, but also maintaining a proper hygiene by the patient. Purpose. In this study, we insisted on the responsibility that rehabilitated patients through implant supported restorations should assume. Material and method. The study was conducted between March 2016 and March 2018 on a group of 73 patients rehabilitated by fixed implant supported restorations using a questionnaire consisting of 7 questions. Results and discussions. Maintaining a high degree of hygiene by regular or professional means of implant-prosthetic restorations leads to prolonging their life span. For this, it is necessary on the one hand for the medical team to make pertinent, logical, sufficient and easy to understand recommendations for all patients and on the other hand for the patients to implement the part of the recommendation that directly targets them. Conclusions. The recommendations of the medical team on oral hygiene after fixed implant supported restorations should be done in a language that is appropriate and easy to understand by patients. To the same extent, the recommendations must be assimilated and respected by patients, as a significant component in maintaining good hygiene in fixed implant supported restorations is the patient

THEORETICAL AND PRACTICAL ASPECTS REGARDING THE IMPLANT-PROSTHETIC REHABILITATION IN SMOKER PATIENTS – PRELIMINARY STUDY

Implant-prosthetic rehabilitation (both the surgical step of inserting dental implants and also the stage of creating the implant-supported prosthetic restorations) in smokers patients poses particular problems not only for the medical team but also for the patients (and here we refer in particular to the average number of cigarettes smoked daily). Purpose. In this paper we have attempted to present a multitude of factors both theoretical and practical, which can intervene in the implant-prosthetic rehabilitation of heavy smoker patients. Material and method. The study was conducted between April 2018 and November 2018 by applying a questionnaire with 6 questions. The 31 subjects enrolled in the study were aged between 29 to 67years old, specialists and/or primary doctors of general dentistry, dental prosthodontics or dental surgery. Results and discussions. Centralized results have been processed to provide a clearer picture of the current attitude towards heavy smokers for oral rehabilitation with the implant-supported restorations. Conclusions. The insertion of dental implants and subsequent creation of implant-supported restorations are not an interdiction for heavy smokers (up to 60 cigarettes a day) but requires the involvement of both the medical team and especially the patients in the follow-up care period to increase long-term success of dental implants and prosthetic restorations made thereon

GUIDED SURGERY TECHNIQUE – REVIEW OF ACCURACY AND ERRORS

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

PRELIMINARY STUDY ON ANTIMICROBIAL EFFICIENCY OF SOME COMMON CHEMICAL SUBSTANCES WITH A DISINFECTING CHARACTER ON IMPRESSION MATERIALS USED IN IMPLANT-PROSTHETIC REHABILITATION

Purpose. Starting from a very recent event on the market of disinfectants, where for many years very diluted disinfectant products were marketed in Romania, the antimicrobial activity being non-existent, we tried, on the basis of simple experiments, to study the antimicrobial efficiency of the active substances of some common products used on impression materials in implant-prosthetic rehabilitation, but also in classical dental prosthetics and in orthodontics and dentofacial orthopedics, products approved and used in the European Union. Material and method. 7 decontamination and/or disinfectant products were tested for qualitative screening for the sensitivity to different microbial strains as well as for quantitative testing of antimicrobial activity. Results and discussions. The study results for the two objectives are influenced by the active substances of the tested products. Conclusions. Decontamination of dental impressions must also become a certainty in implant-prosthetic rehabilitation, in classical dental prosthetics and in orthodontics and dentofacial orthopedics even if this work is disregarded and ignored by many practitioners

ASPECTS OF TESTING THE ADHESION ABILITY OF MICROORGANISMS FROM ORAL CAVITY TO COMMON IMPRESSION MATERIALS USED IN IMPLANT - PROSTHETIC REHABILITATION

Purpose. The adhesion ability of microorganisms present in the oral microbial plaque is a certainty for solid surfaces at this level (including coronal restorations, classical prosthetic restorations and implantsupported restorations fixed and mobile, orthodontic appliances). Therefore, in this study, we have attempted to demonstrate the ability of these microorganisms from the oral cavity to adhere on the surface of some common impression materials used in implant-prosthetic rehabilitation. Material and method. The study was conducted on the main impression materials used in implant supported prosthetic restorations as well as in dental medicine: irreversible hydrocolloids, zinc oxide eugenol pastes, polyethers, condensation and addition silicones. The study was conducted between June and July 2017. Results and discussions. With the help of microorganisms isolated from the 87 patients, an inoculation of standard samples of impression materials was performed. Verification of adherence was achieved at different time intervals, the results being significant. Conclusions. For the tested materials, it was noted that the degree of adhesion was either influenced by the products incorporated in the base substance or by the secondary products resulted from chemical setting of material

CONTROVERSED ASPECTS REGARDING POLYMERIZATION IN DENTAL TECHNOLOGY

Introduction. Any new class of materials almost always brings with it a new processing technology, regardless of the field in which it is operated. If this technology is not fully respected, all the benefits and performance of the material can be compromised. Purpose. In this material we tried not only a familiarization of the dental technicians, but rather their awareness regarding the polymerization processes, which intervene in various technologies for creating prosthetic restorations of any kind. Material and method. For this study, 53 dental technicians, who have completed various forms of schooling, answered 10 questions related to the different forms of polymerization used in the dental technology. Results and discussions. The answers obtained give us an image regarding the knowledge of the practitioners in this field, but also the way in which the theoretical knowledge is verified in practice by the daily experience of the respondents. Conclusion. There is a variation in the accumulated knowledge, a variation that can be based both on the studies followed by each participant in the study and on how they use the materials discussed in this article in daily practice

SINGLE TOOTH EDENTATION CAUSED BY MISSING OF THE 6-YEAR MOLLAR (MAXILLARY AND/OR MANDIBLE) – CONSEQUENCES AND FIX PROSTHETIC TREATMENT SOLUTIONS

The loss of first permanent molars, maxillary and/or mandibular, can lead in time, due to the lack of prosthetic restoration, to a series of complications, some of high gravity, which can cause not only severe difficulties in subsequent prosthetic rehabilitation, but also substantial additional costs for patients. Purpose. Thus, in this material we tried to bring to the attention of dental practitioners the most truthful arguments, for a fixed prosthetic restoration as early and efficient as possible. Material and method. 53 dental practitioners, from different cities of the country, took part in this study conducted between May 2017 and April 2019. Results and discussions. The answers obtained by applying the questionnaire were analyzed statistically and exposed for a better understanding by clear graphical methods. Conclusions. The restoration of this type of single tooth edentation produced by the absence of the 6-yearold molar, regardless of location (maxillary and / or mandibular), is considered by most dental practitioners to be relatively simple, regardless of the therapeutic option selected

THEORETICAL AND PRACTICAL CONSIDERATIONS IN THE TREATMENT OF MORPHOFUNCTIONAL IMBALANCES OF DENTO-MAXILLARY SYSTEM FOR THE AGE PERIOD AFTER 12 YEARS – PRELIMINARY STUDY

This age period after 12 years is characterized by an increase in all dimensions of all the anatomical structures of the individuals, under the influence of new factors that interfere with the general tonus of the body. Purpose. Thus, in this paper, we approached certain aspects of both theoretical and practical that may occur in the formation and development of dento-maxillary system in the age period of 12 years (after some authors, up to the age of 21 years). Material and method. The study was conducted between May 12 and June 25 2018 with the help of 55 dental practitioners. Results and discussions. The analysis of the answers provided by the participants in the study was performed by means of specific research methods. The results are eloquent and provide an overview of how dental practitioners manage the eruption of the wisdom tooth in the developmental processes of the dento-maxillary system. Conclusions. The eruption of the wisdom tooth is a certain element of growth, which must be taken into account in the future therapeutic approach of the morpho-functional imbalances of the dento-maxillary system
