ERO-Plenary Session Spring 2021 the FDI World Dental Federation objectives

Dear Readers,

It gives me great pleasure to address you once again as President of the European Regional Organization (ERO) of the FDI World Dental Federation. As a follow-up to our General Assembly, which took place online as a live stream with simultaneous interpretation on Saturday 17 April 2021, I would like to give you an insight into the topics and decisions of this important meeting. The Corona pandemic has changed many things, but nothing as much as the way we meet each other. Distance and social distancing determine our everyday life and our work. Although it is difficult for us dentists to keep our distance from our patients, we have discovered that many things can also work well over long distances – especially in the field of professional politics.

In short, our online General Assembly was a huge success and showed that ERO is fully capable of taking decisions even under pandemic conditions. Delegates from dental organizations from 34 European countries took part in the virtual meeting. It will certainly be possible to hold larger meetings again in the near future, but Corona has also shown us alternatives that help save resources. (read more)

EFFICACY OF BIOFLAVONOIDS OF FLAVOBAC™ AGAINST SEVERE ACUTE RESPIRATORY SYNDROME – CORONAVIRUS 2 IN VITRO

DOI: https://doi.org/10.25241/stomaeduj.2021.8(2).art.1

The emergence of the novel human Severe Acute Respiratory Syndrome CoronaVirus-2 (SARS-Cov-2) has caused drastic damage to the globe with a dramatic loss of human life worldwide. To date (4 June 2021), approximately 172 million cases have been confirmed with over 3.7 million deaths according to WHO [1]. Previous studies confirmed that viral loads are high in the nasal cavity, nasopharynx, and oropharynx [2-5]. SARS-CoV-2 viral RNA levels (measured in saliva, throat and nasal swabs) are highest at the time of, soon after, or before symptoms and SARS-CoV-2 RNA are detected in saliva and throat swab specimens in recovered patients 5 to >40 days following hospital discharge [6]. Furthermore, live SARS-CoV-2 was isolated from throat swab specimens, indicating viral replication and shedding are active in tissues of the upper respiratory tract where SARS-CoV-2 is not thought to replicate [7] (read more)

TESTING POSSIBILITIES OF MATERIALS USED IN PERIODONTAL THERAPIES ON LABORATORY RATS

DOI: https://doi.org/10.25241/stomaeduj.2020.8(2).art.2

Periodontal disease is known to have a a long history, constantly accompanying the evolution of the human species. New data regarding its prevalence confirm its high value up to 50% around the world, with the highest scores in the older population [1]. It represents one of the major causes of tooth loss which can compromise mastication, esthetics, selfconfidence, and quality of life [2]. Microbial dental plaque has been accepted as the primary etiological factor in the occurrence of inflammatory disease. Therefore, the major goal of periodontal therapy was to eliminate the pathological organisms discovered in the dental plaque located on the surface of the tooth [3,4]. Periodontal therapy is complex and it includes: prevention strategies to control the inflammation level and regenerative therapies of all supporting structures and tissues [5]. Root planing leads to clinical improvement by disrupting the subgingival biofilm, which reduces the amount of bacteria, resulting in a delay in the repopulation of pathogenic microorganisms [6,7]

CONE BEAM TOMOGRAPHY AND PANORAMIC RADIOGRAPHY IN LOCALIZATION OF IMPACTED MAXILLARY CANINE AND DETECTION OF ROOT RESORPTION

DOI: https://doi.org/10.25241/stomaeduj.2021.8(2).art.3

Maxillary canines play important roles in facial esthetics, dental arch development, and oral cavity functions. Non-erupted maxillary canines are relatively common because these teeth develop deep within the maxilla and follow a longer path to erupt into the oral cavity when compared to other teeth [1]. An impacted tooth can be defined as the tooth that has failed to erupt into the proper position in the dental arch within the normal period of growth, and maxillary canines are the most common teeth suffering from impaction except third molars. The prevalence of their impaction ranges from 1% to 3% in the general population [2-4].
The determination of impacted canine positions is critical for the planning of orthodontic-surgical treatment. The panoramic radiographic evaluation is the most common clinical approach used by orthodontists for this procedure. It should be known, however, that panoramic radiographs have some limitations in evaluating the labiopalatal positions of impacted canines [5]. In addition, it is difficult to localize and determine the root resorptions of adjacent teeth with this radiographic method because of the superimposition of the related structures, leading to a difficulty in distinguishing many significant details [6].(read more)

OSTEOSYNTHESIS MATERIALS IN MAXILLOFACIAL SURGERY: REJECTION, REMOVAL, CORROSION AND PARTICLE DETECTION RATES

DOI: https://doi.org/10.25241/stomaeduj.2021.8(2).art.4

The use of plates and screws for osteosynthesis is the golden standard in maxillofacial surgery. In the literature, a wide range of different types of materials are used for different purposes, and each type of material has its own properties. Stainless steel was the first type of material to dominate the market, but it has been left behind due to its toxic and corrosive properties [1]. Stainless steel was replaced by titanium as the golden standard for osteosynthesis, which was found to be much more efficient, because of its non-toxicity and corrosion-resistance [1]. Since the introduction of titanium, an important evolution has been witnessed from standard titanium plates and screws to 3D -designed and -manufactured (CAD/CAM) titanium plates and screws [2,3]. Other contenders in this field are the bioresorbable materials, which in theory are interesting because of their bioresorbable aspects and the possibility to avoid a second surgery to remove the osteosynthesis material [4,5]. Several studies have analyzed these different types of materials in detail, proving each material has its own advantages and disadvantages. However, an overview comparing the complication rates of the different material types is lacking. The aim of this narrative review was to compare the complication rates related to osteosynthesis materials and reconstruction plates in terms of rejection, removal, corrosion and particle detection in soft tissues.

DOI: https://doi.org/10.25241/stomaeduj.2021.8(2).art.5

Nowadays patient-information sources on medical issues are numerous and diverse. In fact, online resources are an important category, they are used considerably more frequently, with an impact that still needs to be better known considering their various content and sometimes doubtful credibility [1,2]. Among the online resources, videos are a particular category that registers an increased use, being a good tool for medical information for both the public and medical professionals [3]. They can be accessed on different platforms, among which YouTube is one of most popular. Previous research that assessed the information quality of medical aspects presented by online videos suggested that YouTube is not currently an appropriate source of information, considering sometimes it spreads misinformation [4,5].

Intra-oral repair of ceramic chipping using resin composite: a step-by-step technique

https://www.stomaeduj.com/wp-content/uploads/Ozcan.pngDOI: https://doi.org/10.25241/stomaeduj.2021.8(2).art.6

Despite advances in digital laboratory strategies to manufacture tooth- and implant-supported fixed dental prostheses (FDP), obtaining personalized esthetic results, especially in anterior areas, still depends on traditional ceramic stratification techniques. In these techniques, feldspar porcelain is applied on the framework, layer by layer, using powders with different colors and opacities [1]. An excellent esthetic result is obtained in multi-layered prostheses; however, an interface is generated between the framework and the veneering ceramic, representing the most fragile link of this type of restorations [2]. Thus, chipping and fractures of the veneering ceramic are frequently observed in such FDPs [3]. This is due to the lower strength of porcelain compared to the material used in the framework (metal or zirconia); the presence of residual stress resulting from the incompatibility of the thermal expansion coefficients (CET) between the materials, and the tension resulting from the cooling that occurs after ceramic sintering [3,4].  (read more)

Technical complications of implant restorations: Component deformation, fracture, separation

DOI: https://doi.org/10.25241/stomaeduj.2021.8(2).art.7

With the global market for implants expected to double in the next decade [1], more general practitioners are placing, restoring, and maintaining dental implants [2]. However, follow-up care and maintenance amounts to almost a third of the total treatment costs [3], which makes servicing implant restorations and understanding failures paramount. Screw loosening, the primary complication of screw-retained implant restorations, is considered a reversible complication as long as there is no significant deformation to the implant or superstructure connection. Other complications related to component wear, deformation fracture, or separation of different materials in a heterogenous system are irreversible and may or may not be related to screw loosening. This article aims to review these other less common complications and why they might occur.(read more)

A rare case report of syphilis mimicking an oropharyngeal neoplasm

DOI: https://doi.org/10.25241/stomaeduj.2021.8(1).art.8

An increasing incidence of syphilis is inherently related to an increasing number of atypical presentations of the disease. Syphilis is on the rise and, with the increase in cases, there has been an increase in different and unusual presentations of the disease. Since 2010, reports of syphilis incidence rates in the European Union (EU) have been ever increasing. This trend seems to be accelerating, predominantly amongst male homosexuals [1]. Syphilis is a sexually transmitted infection caused by Treponema pallidum, a well-known pathogen that can cause pathology in the maxillofacial area. Although there is little literature describing oropharyngeal treponema pallidum infections as mimicking an oropharyngeal squamous cell carcinoma (OPSCC), it has been described in rare cases [2]. This case report presents such a case. (read more)
