Insight Into

To date, many studies have examined the development and use of novel materials, enhancing the performance of existing dental composites and improving methods for restoring tooth structure. In recent years, nanotechnology-based techniques have been used to develop a variety of nanomaterial-based dental products aimed at conservative dentistry applications. These new nanomaterial-based materials offer improved physicochemical and mechanical properties, combined with enhanced aesthetics that makes them superior restorative materials in several dental procedures. This review discusses tooth structure, the oral microbial environment, chronic dental diseases such as dental decay (or caries), and periodontal disease, as well as systemic diseases in light of nanotechnology-based preventative and restorative dental filler product advancements. Considerations regarding human health and safety associated with the use of nanomaterials in dentistry are discussed. Lastly, knowledge gaps and limitations including future perspectives warranting further research are outlined. The study is followed by a conclusion which condenses the extensive data into a brief summary to establish a link between new nanomaterials and human interactions. This paper draws out and distils the current findings that have emerged from a substantial bibliographical review of a range of articles to provide an insight into the use and development of novel nanomaterials for preventive and restorative dentistry.

Background: Dental schools are considered to be a very stressful environment; the stress levels of dental students are higher than those of the general population. The aim of this study was to assess the level of stress among dental students while performing specific dental procedures. Methods: A survey was conducted among 257 participants. We used an original questionnaire, which consisted of 14 questions assigned to three categories: I—Diagnosis, II—Caries Treatment, and III—Endodontic Treatment. Each participant marked their perceived level of stress during the performed dental treatment procedures. The scale included values of 0–6, where 0 indicates no stress, while 6 indicates high stress. Results: Third- (p=0.006) and fourth-year (p=0.009) women were characterized by a higher level of perceived stress during dental procedures related to caries treatment. Caries treatment procedures were the most stressful for 18.3% of third-year students, 4.3% of fourth-year students, and 3.2% of fifth-year students. Furthermore, 63.4% of third-year students, 47.3% of fourth-year students, and 17.2% of fifth-year students indicated that they felt a high level of stress when performing endodontic procedures. Conclusion: Third- and fourth-year female students are characterized by a higher level of stress during caries and endodontic treatment procedures. The most stressful treatments for participants were endodontic treatment procedures.

This study was carried out to evaluate the difference in prices for dental treatments carried out privately in general dental practice within the Birmingham area. Ten different practices were chosen at random, which were spread across Birmingham, in order to get a better insight into the differences across the districts. Their prices for pre-determined dental procedures were procured off the practices’ respective websites or through telephoning. The findings of this study have shown a wide variation in prices for each dental procedure, with the greatest variation in prices between practices being £850 for dental implants. The procedures with the lowest average cost were fissure sealants at £23.14. The procedure with the highest average cost was dental implants at £2,261.11. This study also showed that as more dental treatment was required, the mean cost for the dental intervention increased, regardless of the tooth being treated.

Aim. To study the influence of dental diseases and results of their treatment on patient’s psychological profile. Methods. 40 patients with hard teeth tissues and dentition defects at the esthetic zone aged from 30 to 57 years were included in the study. Control group consisted of 25 people not requiring dental treatment. A new method of determining patient’s psychological subtype, offered by A. Anuashvili and based on computer analysis of the patient’s photographs, allowing totally avoid the subjectivity of a diagnosis. Results. Analysis of emotional stress level in patients before the dental procedures showed that it was significantly higher in males compared to females (73.6±0.86 vs 57.9±0.93% respectively, р 0,01). It was also found that 60% of all patients had unstable aspects of psychological subtype regardless of gender. In the control group, only minor changes of psychoemotional state between two examinations were registered, allowing to conclude that psychoemotional state without strong stimuli is quite stable. The use of the video-computed psychoanalysis method can help a dentist to assess the patient’s psychoemotional status when patient is seeking for dental aid, and to communicate better considering the patient’s psychological subtype, as well as to control psychoemotional state during and after the treatment. Conclusion. Missing teeth not only impair chewing, but also deteriorate patient’s psychoemotional state, leading to worse quality of life.

The Impact

The objective of this study was to investigate the oral microbial composition of the donkey and whether basic dental treatment, such as dental floating, would make a difference to the oral microbial environment in donkeys with dental diseases using high-throughput bacterial 16S rRNA gene sequencing. Oral swab samples were collected from 14 donkeys with various dental abnormalities on day 0 (before treatment) and day 20 (twenty days after treatment). It is the first report focusing on the oral microbiome in donkeys with dental diseases and the impact of common dental procedures thereon. Identified in group Day 0 and group Day 20, respectively, were 60,439.6 and 58,579.1 operational taxonomic units (OTUs). Several taxa in Day 0 differed significantly from Day 20 at the phylum and genus levels, but no statistically significant difference was observed in richness and diversity of Day 0 and Day 20. The results also indicated that a larger-scale study focusing on healthy donkey oral microbiome, as well as the correlation of dental diseases and oral microbiomes at different time frames following more specific and consistent dental treatment, are warranted.

Insight Into

Aims: Open drug scenes can be found in most major cities in Europe. Despite often being closed down by the police, the drug community continues to exist, and the drug scenes reappear elsewhere. There seem to be forces that hold these communities together, regardless of the substances used. In this study we explore whether interaction rituals have an impact on the decision by people to stay in the drug scene or to return after quitting their drug use. Method: In this ethnographic study, one of the researchers spent time in an open drug scene in a Norwegian city over a one-year span and gathered data on the human interactions hosted by this scene. In addition, the researcher interviewed eight people from the scene to obtain greater insight into their lives and perceptions of the scene, drawing on Goffman’s and Collins’s theories about rituals. Findings: Three themes emerged. First, drug users bonded as a group and resisted what they called “normal people” passing by. Second, users demonstrated the importance of sharing drugs and services and adhering to the scene’s rules of conduct. The third and final theme is the focus of attention and the production of emotional energy. Conclusion: The experience of being outsiders and the need to hide some of their activities seemed to make it necessary for persons in the drug scene to have their own rules and rituals. These rules and rituals can be regarded as “interaction rituals”. They provide participants with the symbols of group membership, emotional energy, and group solidarity. This makes it hard to leave the scene and might explain why those who do often return.
