Background and Objectives: Halitosis is a condition characterized by unpleasant breath smell that is starting to receive serious scientific attention, considering it reflects on people’s social and personal life. While most studies focus on the prevalence of halitosis, its medical etiology, and the psychological impact on adults, there is a lack of evidence regarding the social impact of halitosis on the younger population. Therefore, this systematic review aimed to observe the social and emotional impact that halitosis has on adolescents and young adults. Materials and Methods: The review followed the PRISMA protocol, and four electronic databases (Scopus, Scholar, Web of Science, and ProQuest) were searched. From a total of 593 studies retrieved, only 6 were included in the study after assessing the eligibility criteria. Results: The main results showed that the levels of self-reported halitosis ranged from 23.1% to 77.5%, with an average of 44.7%, indicating a significant heterogeneity among the studies reporting this issue. Adolescents and young adults who experienced bad breath were feeling more anxious and depressed according to the non-standardized questionnaires and the standardized questionnaires (OHIP-14 and SCL-9-R). The respondents were isolated from social interactions and consequently had lower self-esteem and impaired quality of life. Conclusions: The conclusions drawn indicate the need for action on a medical level, as well as on a psychological level, in order to improve people’s oral health and help them navigate through the difficulties of maintaining social interactions as they live with halitosis.

This study tries to identify the influence of the new coronavirus pandemic on dental education by assessing dental students’ perception and their didactic performance regarding virtual and traditional lectures. The final academic performances of students from different years of study at the Faculty of Dental Medicine who participated in undergraduate courses through two different lecturing modes (traditional and virtual) were compared. The same students were evaluated in terms of their preference between the two lecturing techniques. There was a statistically significant difference in the mean values for final grades of virtual and traditional technique in favor of the latter one. In pandemic conditions, because of safety reasons, virtual lecturing was the most preferred technique. For dental faculty, this process of transitioning from traditional to virtual is a continuous process, which was suddenly imposed, but which at this moment offers multiple opportunities from a didactic point of view. Analyzing the grade, the virtual lecturing techniques demonstrated superior didactic performance. Although students preferred the virtual lecturing technique more than the traditional one, better-designed research is required to verify the long-term effect of the two lecturing techniques on students’ formation and deepening of knowledge.

The objective of this study is to determine prevalent behaviors and knowledge of oral hygiene on the late adolescents. Only individuals in the late stage of adolescence, specifically between the ages of 18 and 24, that were students from the “Ovidius” University of Constanta were chosen. The involvement was optional. A printed questionnaire was provided for them to complete. A total of 50 participants took part in this study, consisting of 26% (n=13) males and 74% (n=37) females. When asked about their toothbrush preference, 50% (n=25) individuals indicated using just manual toothbrushes. Out of all individuals who have utilized orthodontic appliances, 70.8% (n=17) reported that the dentist recommended for them to receive professional dental hygiene care while undergoing treatment. 78.0% (n=39) individuals reported participating in oral hygiene meetings and would be interested for additional information regarding the topic. It is essential to provide youngsters with early instruction about the importance of oral hygiene in order to develop long-lasting healthy habits.

Background and Objectives: Cigarette smoking is a recognized risk factor for periodontal disease and subgingival dysbiosis; however, the impact of electronic cigarettes on the subgingival microbiome in young adults is still not sufficiently investigated. This study aimed to characterize and compare the carriage and bacterial load of 20 subgingival species among young adult cigarette smokers, e-cigarette users, and non-smokers, and to evaluate whether e-cigarette use is linked to a periodontopathogen-enriched profile similar to that of smoking. Materials and Methods: In this exploratory cross-sectional study, fifty young adults were divided into three groups: cigarette smokers (n = 18), e-cigarette users (n = 16), and non-smokers (n = 16). Subgingival specimens were examined using real-time Polymerase Chain Reaction (PCR) (Perio panel; ADD Laboral B.V., Malden, The Netherlands) for 20 bacterial species. Carriage was analyzed across groups utilizing Fisher’s exact test with Cramér’s V as the effect size, while bacterial load was assessed using the Kruskal–Wallis test accompanied by Dwass–Steel–Critchlow–Fligner post hoc comparisons (jamovi; significance threshold established at p < 0.05). Results: Red-complex pathogens were more prevalent and present in greater quantities in smokers and e-cigarette groups compared to non-smokers. Porphyromonas gingivalis prevalence was seen in smokers (94.4%), vapers (75.0%), and non-smokers (56.2%; p = 0.028), whereas Tannerella forsythia was found in 100% of smokers, 87.5% of vape users, and 68.8% of the non-smokers (p = 0.022). Aggregatibacter actinomycetemcomitans was not present in non-smokers but was identified in 37.5% of vapers and 16.7% of smokers (p = 0.018), whereas Eubacterium nodatum was significantly elevated in tobacco users (p = 0.012; Cramér’s V = 0.449). In contrast, Prevotella nigrescens was predominant among non-smokers (87.5%; p = 0.022). Conclusions: In young adults, the red-complex bacteria—Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola—were found more frequently and in larger quantities among smokers and vapers as compared to non-smokers.
