Regardless of the demonstrable success of fixed appliances like implants for the replacements of missing natural teeth in partially and fully edentulous patients, countable hindrances still persist. A crucial role is played by impressions used in the fabrication of dental implants for the success, durability and outcome of the restoration. An impression is a three dimensional negative likeness of the future position of the implant in the oral cavity. In view of the absence of periodontal ligaments that serve as natural compensators of the slight but significant details of the impression surface, therefore, impressions in implants are very crucial for implant success. Taking this factor into consideration, the present review article emphasizes on the different types of impression techniques used in implant dentistry.

Stromal Stem Cells

The oral cavity as the second most various microbial community in the body contains a broad spectrum of microorganisms which are known as the oral microbiome. The oral microbiome includes different types of microbes such as bacteria, fungi, viruses, and protozoa. Numerous factors can affect the equilibrium of the oral microbiome community which can eventually lead to orodental infectious diseases. Periodontitis, dental caries, oral leukoplakia, oral squamous cell carcinoma are some multifactorial infectious diseases in the oral cavity. In defending against infection, the immune system has an essential role. Depending on the speed and specificity of the reaction, immunity is divided into two different types which are named the innate and the adaptive responses but also there is much interaction between them. In these responses, different types of immune cells are present and recent evidence demonstrates that these cell types both within the innate and adaptive immune systems are capable of secreting some extracellular vesicles named exosomes which are involved in the response to infection. Exosomes are 30–150 nm lipid bilayer vesicles that consist of variant molecules, including proteins, lipids, and genetic materials and they have been associated with cell-to-cell communications. However, some kinds of exosomes can be effective on the pathogenicity of various microorganisms and promoting infections, and some other ones have antimicrobial and anti-infective functions in microbial diseases. These discrepancies in performance are due to the origin of the exosome. Exosomes can modulate the innate and specific immune responses of host cells by participating in antigen presentation for activation of immune cells and stimulating the release of inflammatory factors and the expression of immune molecules. Also, mesenchymal stromal/stem cells (MSCs)-derived exosomes participate in immunomodulation by different mechanisms. Ease of expansion and immunotherapeutic capabilities of MSCs, develop their applications in hundreds of clinical trials. Recently, it has been shown that cell-free therapies, like exosome therapies, by having more advantages than previous treatment methods are emerging as a promising strategy for the treatment of several diseases, in particular inflammatory conditions. In orodental infectious disease, exosomes can also play an important role by modulating immunoinflammatory responses. Therefore, MSCs-derived exosomes may have potential therapeutic effects to be a choice for controlling and treatment of orodental infectious diseases.

Introduction. The period of higher education, between 19 and 25 years of age, is often connected with the change of dietary habits of a young person. “Student lifestyle” can lead to systemic diseases, including lesions and diseases of the oral cavity. Aim of the study. To perform analysis of dietary habits and awareness of healthy eating among students. Materials and methods. A total of 328 respondents took part in the survey, including 287 women and 41 men. The study was based on a 50-question questionnaire. The questionnaire provided the sociodemographic information as well as changes in students’ dietary habits during the course of their education, the quality, frequency and type of consumed meals and the regularity and duration of their consumption. Results. 75.6% of respondents reported that they had changed their diet during studies. 18.6% of students increased the frequency of meals and 48.2% decreased the frequency of meals. Both men and women most often consumed 3-4 meals a day. It was noticed that the respondents regularly had breakfast, dinner, and lunch, with up to 25.6% of students claiming to have the biggest meal late in the evening and at night. 70.9% of students reported breaks between their meals lasting longer than three hours. It was noticed that 38.8% had the last meal later than two hours before bedtime. Frequent snacking between meals was declared by 39.6%. Conclusions. During the university studies, students change their dietary habits. Students are aware of the principles of proper nutrition, but it is not reflected in their lifestyle.

The long-standing hypothesis that the neonatal microbiome is acquired during and after birth has been challenged by recent studies in humans using advanced molecular technologies, which identified bacteria and bacterial DNA and RNA in amniotic fluid, placenta, and meconium. Similar studies have recently been conducted on canine neonates, giving a description of the gut microbiota of newborn puppies and a comparison of different types of parturition on theirdevelopment. In this review, we summarize the current knowledge of microbiome and microbial alterations in the canine gut, vagina and oral cavity throughout pregnancy, and their effects on the microbiome of the placenta and the meconium in neonatal puppies. We further compare the microbiome knowledge gained in the last decade on human neonates and draw parallels with canine pregnancy and the neonatal microbiome.

AbstractThe objective was to describe and compare the positions of different types of bits within the horse's oral cavity. Eight horses were fitted with a bridle and six bits [jointed snaffle ( JS), Boucher, KK Ultra, Myler snaffle (MylerS), Myler ported barrel (MylerPB), Myler correctional-ported barrel (MylerCPB)]. Lateral radiographs and custom software were used to measure the position and orientation of the bits relative to the horse's palate and second premolar teeth without rein tension and with 25±5 N bilateral rein tension. The results showed differences in the position of the bits within the horse's oral cavity and in their movements in response to rein tension. Without rein tension, single-jointed bits were further from the premolar teeth ( JS 32.2±10.6 mm; Boucher 33.9±10.8 mm) than the Myler bits (MylerS 20.2±9.7 mm; MylerPB 12.8±6.7 mm; MylerCPB 14.6±4.3 mm). Single-jointed bits moved closer to the premolars when tension was applied to the reins (JS 20.8±6.3 mm; Boucher 19.7±6.8 mm). The cannons of the Boucher were more elevated than those of the other bits. The cannon angulation decreased significantly from 38.7±13.7 deg. to 21.6±6.9 deg. for JS and from 43.1±10.1 deg. to 27.8±10.1 deg. for the Boucher when tension was applied to the reins. The Myler bits showed minimal change in position in response to the application of rein tension.

Anaerobic Microbial Community

The gastrointestinal tract (GIT) of vertebrates is colonized by an extremely diverse anaerobic microbial community consisting of archaea, bacteria, fungi, and various protozoa. Trichostomic ciliates are among the most characteristic and largest protists of this complex enzymatic association, inhabiting both the anterior and posterior parts of the gastrointestinal tract. The transfer of ciliates – endobionts, occurs more often when animals come into contact with other animals of the herd. Regurgitation in cattle occurs reflexively, regularly and frequently, while a significant number of ciliates penetrate the oral cavity. In most ruminants, such social behavior as grooming involves licking the muzzle and sometimes the oral cavity of relatives, with some ciliates being transferred from the mouth of one animal to the mouth of another and soon swallowed. According to the results of PCR-studies of endobiotic ciliates from the rumen of cows for the presence of bovine leukemia virus (BLV) in them, a negative result was obtained in all samples. Thus, in a homogenized material consisting of different types of ciliates from 12 cows that were spontaneously infected, a PCR methods was obtained negative for the presence of the genetic material of bovine leukemia virus. In our opinion, the data obtained do not completely disprove the hypothesis of endobiotic transmission of BLV due to the relatively small sample of carrier animals and insufficient improvement of the PCR diagnostic method, and these studies should be continued using a larger number of infected with BLV animals and different diagnostic methods.
