Orthodontic Elastics: A Multivariable Analysis of YouTubeTM Videos.

Background/Purpose: Whether YouTube videos contain precise and adequate information on certain orthodontic procedures remains unclear. This study aimed to investigate the content and quality of YouTube videos on orthodontic elastics and identify the predictors of high-level content YouTube videos. Materials and Methods: Two hundred YouTube videos were screened for eligibility, and after applying the inclusion criteria, 133 videos were excluded. Student's t-test was used to compare the characteristics, quality parameters, and total content of the low-level and high-level content videos. Chi-square or Fisher's exact tests were implemented to identify the source and content element differences across low-level and high-level content videos. Pearson's correlation coefficients were used to determine the relationship between the total content score, video information and quality index (VIQI), and YouTube characteristics. Stepwise linear multiple regressions with forward selection were used to test the association of the YouTube characteristics and VIQI with the total content score. Results: Among 67 included videos, only 19.4% of videos were classified as high-level content videos. High-level content videos had significantly higher mean number of likes (MD = 4041.7; SD = 4680.7; P-value=0.0068), VIQI score (MD = 4.17; SD = 4.87; P-value=0.0073), and total content score (MD = 4.04; SD = 1.23; P-value=<0.0001). The adjusted linear regression model demonstrated a significant association between the total content score and VIQI, where 1 unit increase in the VIQI was significantly associated with a 0.16 increase in the total content score (B = 0.16; standard error [SE]=0.04; P = 0.0003). Further, a significant association was observed between the total content score and video duration, where 1 minute increase in the video duration was significantly associated with a 0.15 increase in the total content score (B = 0.15; SE = 0.05; P = 0.008). Conclusion: This study demonstrated that YouTube content quality concerning orthodontic elastics is poor. Thus, future implementation of online visual content provided by certified orthodontists will ensure accurate and thorough information delivery.

Salivary interleukin-17A and interleukin-18 levels in patients with celiac disease and periodontitis.

Background: An increased level of interleukin-17A and interleukin-18 in the serum and intestinal mucosa of celiac disease patients reflecting the severity of villous atrophy and inflammation was documented. Thus, the objective of this study was to evaluate the concentrations of salivary-17A, interleukin-1 beta, and interleukin-18 in patients with celiac disease who are on a gluten-free diet, both with and without periodontitis, and to compare these levels with those in healthy individuals. Methods: The study involved 23 participants with serologically confirmed celiac disease (CD) and 23 control subjects. The CD patients had been following a gluten-free diet (GFD) for a minimum of 1 year and had no other autoimmune disorders. The research involved collecting demographic data, conducting periodontal examinations, gathering unstimulated whole saliva, and performing enzyme-linked immunosorbent assays to measure salivary interleukin-17A, interleukin-1 beta, and interleukin-18 levels. Spearman's correlation analysis was utilized to explore the relationships between CD markers in patients on a GFD and their periodontal clinical findings. Results: The periodontal findings indicated significantly lower values in celiac disease patients adhering to a gluten-free diet compared to control subjects (p = 0.001). No significant differences were found in salivary IL-17A, IL-18, and IL-1B levels between celiac disease patients and control subjects. Nevertheless, the levels of all interleukins were elevated in periodontitis patients in both the celiac and control groups. The IL-1 Beta level was significantly higher in periodontitis patients compared to non-periodontitis patients in the control group (p = 0.035). Significant negative correlations were observed between serum IgA levels and plaque index (r = -0.460, p = 0.010), as well as gingival index (r = -0.396, p = 0.030) in CD patients on a gluten-free diet. Conclusion: Celiac disease patients on gluten-free diet exhibited better periodontal health compared to control subjects. However, increased levels of salivary IL-17A, IL-18 and IL-1B levels were associated with periodontitis. Additionally, serum IgA level was significantly inversely associated with periodontitis clinical manifestations and with salivary inflammatory mediators in CD patients on GFD.

Remineralization Effect of Zamzam Water on Initial Artificial Carious Lesion of Permanent Teeth.

INTRODUCTION: Chemical testing showed that Zamzam water is completely safe to drink and has health benefits due to its high percentage of sodium, calcium, magnesium, and many other minerals. The purpose of this study was to evaluate the remineralization effect of Zamzam water on extracted premolars using the Vickers Microhardness test. METHODS: Teeth samples (N=40) with artificially induced carious lesions were divided randomly into four groups: Study group (I) treated with agitated Zamzam water (n=10), study group (II) treated with non-agitated Zamzam water (n=10), control positive group (III) treated with sodium fluoride (n=10), and control negative group (IV) treated with deionized water (n=10). Teeth were subjected to microhardness testing before and after artificial demineralization and after remineralization treatment within the four groups. RESULTS: Following treatment with different solutions in both study and control groups, there was an increase in microhardness after remineralization but with varying degrees. The highest increase in microhardness was shown after remineralization with sodium fluoride followed by agitated Zamzam water. CONCLUSION: Zamzam water with agitation causes an increase in the microhardness of the enamel surface after demineralization. Zamzam water is an effective remineralizing agent in initial carious lesions, and its efficacy is comparable to that of sodium fluoride.

Dental Anxiety Screening and Management Practices in Dental Practice in Eastern Province, Saudi Arabia.

Purpose: The purpose of the study was to investigate dental anxiety (DA) screening and management practices among dental professionals in Saudi Arabia. The study also evaluated correlation between patients' self-reported DA and dentists' ratings of patients' DA. Participants and Methods: This cross-sectional observational study included dentist/patient pairs (N = 279) from the Eastern Province of Saudi Arabia. The dentists responded to a questionnaire about their DA screening and management practices and they evaluated patients' DA using the visual analogue scale (VAS). In addition, patients responded to the Modified Dental Anxiety Scale (MDAS) to measure their DA. Results: About 15.1% of dentists reported using a published scale for screening DA in dental practice and Corah's Dental Anxiety Scale and Dental Fear Survey were their main scales. However, 69.2% reported directly asking their patients about DA. The use of DA management technique was reported by 89.6% of the dentists. Approximately half of the participants (53%) reported receiving DA training in their undergraduate dentistry programs and 65.2% expressed their interest in continuing education courses related to DA. In multiple logistic regression analysis, statistically significant factors associated with DA screening practice included gender (AOR = 0.46, P = 0.037), place of work (AOR = 3.68, P = 0.039), and interest in continuing education courses (AOR = 3.21, P = 0.015). Monthly income (AOR = 0.20, P = 0.029) and directly asking patient about DA (AOR = 6.15, P = 0.025) were significant factors associated with management of patients with DA. The study also showed a significant but weak correlation between DA evaluated by the dentists and DA reported by the patients (rho = 0.185, P = 0.002). Conclusion: The present study showed a low prevalence of DA screening practices among dentists. Dentists' rating of patients' DA weakly correlated with patients' self-reported DA.
