Background: The aim of the study was to determine the facial divergence and lip position combinations that are most and least preferred, and to investigate whether age or gender has an impact on these preferences. Methods: The current investigation was carried out on a sample of 1077 individuals who were not experts in the field (253 men and 824 females). The research employed black silhouette photographs of profiles featuring different lip locations and profile divergences. The recruitment of participants was conducted in order to assess the attractiveness of the profiles, employing a Likert scale. The various positions of the lips and variations in facial profiles were thoroughly categorized. Results were analyzed using the Chi-square test. Results: The findings of the research demonstrated that aesthetic perceptions displayed diversity when considering different lip locations and profile divergences. It was shown that neutral lip positions were predominantly favored, accounting for approximately 40.2% of the total frequencies in the anterior diverging group. It is noteworthy to highlight the aesthetically pleasing features exhibited by those with the most prominent lip position, occurring at a frequency of 10.9% in straight-diverging group. In the posterior divergent group, the most protruded lip position, showed very attractive aesthetics with frequency (7.1%). Gender, age, region, and level of education had significant influence on aesthetic perception. Conclusions: The variety of aesthetic preferences is influenced by the location of the lips and the divergence of the facial profile, resulting in different outcomes within the categories of anterior, straight, and posterior divergence. Clinicians are advised to customize the treatment regimen in order to correspond with the unique desires and preferences of the patient.

Background: One of the most popular cosmetic dental procedures is teeth whitening. The public's comprehension of its safety and appropriate use, however, is still lacking. The purpose of this study is to assess knowledge, attitudes, and practices about teeth whitening among the population in Saudi Arabia. Methods: Using a validated questionnaire, 500 persons in Saudi Arabia participated in a cross-sectional survey. The survey evaluated participant knowledge, opinions, and teeth-whitening behaviors in addition to demographic information. SPSS was used to analyze the data, and a significance level of p < 0.05 was considered significant. Results: Most participants (88%, n=440) understood that getting a dental consultation was necessary before getting teeth whitening. On the other hand, only 29.2% (n=146) thought the bleaching was safe, while 53.6% (n=268) were unsure. Better attitudes and understanding about teeth whitening were substantially correlated with higher educational attainment (p < 0.001). While most people knew that smoking causes tooth discoloration (94.8%, n=474), fewer people knew that other factors, such as too much fluoride, can also cause it (59%, n=295). Conclusion: Most people in Saudi Arabia understand how important it is to get professional advice before bleaching their teeth. However, there are still false beliefs about its safety, especially among the less educated. It is advised to implement focused educational programs to raise public awareness and encourage safer teeth-whitening procedures.

Background/Objectives: Oral nicotine pouches (ONPs) have rapidly gained popularity as a novel nicotine delivery method. However, data on ONP use, awareness, and associated beliefs in Saudi Arabia remain limited. This study aimed to investigate these aspects among adults in Riyadh region. Methods: A cross-sectional survey was conducted in 2024 involving 831 Saudi adults (age ≥ 18 years). Participants completed a self-administered questionnaire assessing ONP awareness, prevalence, beliefs, and susceptibility as well as potential associated ONP use symptoms. Logistic and multinomial regression models were employed to analyze the associations between these variables. Results: Overall, 59.3% of participants reported awareness of ONPs, and 14.2% having used them. Males were more aware (ORadj= 1.97, p< 0.0001) and user (ORadj= 2.86, p= 0.03) of ONP than females. Similarly, younger adults (aged 18-29 and 30-39 years) demonstrated higher ONP awareness (ORadj= 4.67 and 4.88, respectively, both p< 0.0001) and use (ORadj= 6.91, p< 0.002 and 6.12, p< 0.003, respectively) compared to older adults (+40 years). Additionally, 95.8% of ONP users were smokers, more likely to be cigarette (ORadj= 9.53, p< 0.0001) or e-cigarette (ORadj= 8.43, p< 0.0001) smokers. Approximately 60% of participants demonstrated susceptibility to ONP use, characterized by curiosity, limited knowledge of health risks, and potential willingness to use. Favorable beliefs about ONPs were more prevalent among users. Furthermore, a positive correlation was observed between the frequency of ONP use and the likelihood of experiencing associated symptom (r= 0.3, p= 0.0009). Conclusions: Given that 95.8% of ONP users in this study were current smokers, these findings suggest a potential future role for ONPs as a harm reduction strategy within the context of smoking cessation in Saudi population in Riyadh. However, continuous surveillance and targeted public health interventions are crucial to mitigate the potential negative consequences associated with ONP use.

Oral diseases are among the most prevalent non-communicable conditions globally, with inadequate toothbrushing contributing to high rates of dental caries
