Material and Methods: CBCT images of 15 healthy individuals, previously obtained for various reasons, were used in this study. In HU measurements, mineral density measurements were made from three different regions of enamel and three different regions of dentin, and the values obtained were compared. Enamel and dentin mineralization density measurements were measured from six regions, namely the crown cutting edge, buccal middle and cervical region for enamel, and the crown cutting edge, cervical region and root apex for dentin. In the comparisons of groups, the parametric One-Way ANOVA variance analysis method was applied. In the paired comparisons between the groups, the Tukey HSD test was applied as the multiple comparison post hoc test. A value of p<0.05 was accepted as statistically significant. Results: Mineralization density of tooth enamel and dentin tissues was quantitatively different in the maxilla and mandible in anterior and posterior teeth. Conclusion: In all the teeth, there were statistically significant decreases in the mineral density values of enamel and dentin tissue from occlusal towards the cemento-enamel junction. Statistically significant decreases were observed in the mineral density values of enamel and dentin tissue from the anterior region towards the posterior region in the teeth in both the upper and lower jaws.","PeriodicalId":134552,"journal":{"name":"Brazilian Research in Pediatric Dentistry and Integrated Clinic","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135059728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and Methods: A questionnaire was distributed to dental practitioners in all healthcare sectors in Jordan, Egypt, and Saudi Arabia. Results: There was a total of 335 participants, with the majority being females (N=225, 67.2%) and general practitioners (N=202, 60.3%). Cellulitis was the most common emergency encountered (N=108). The most common urgent procedures were for pulpitis, abscesses, and pericoronitis (N=191, 130, and 95, respectively). Country-specific significant associations were pulpitis in Egypt and Jordan, broken symptomatic teeth in Jordan, and biopsy in Egypt (p<0.05). The Ministry of Health was significantly associated with the management of dental infections, avulsion, and orthodontic emergencies, while university hospitals were significantly associated with advanced restorative procedures (p<0.05). Male practitioners performed significantly more procedures, particularly surgical emergencies (p<0.05).

Material and Methods: A cross-sectional descriptive survey was steered among 814 undergraduate dental students (representing first year through internship) in Bhubaneswar, India. Internet addiction was assessed with the Internet Addiction Test (IAT) developed by Young, which consisted of 20 items rated on a 5-point Likert scale. Google Forms were used to collect the data. Statistical tests like Chi-square, Kruskal-Wallis, and Spearman correlation coefficient were used to analyze the qualitative and quantitative variables, respectively, with the significance level set at p ≤ 0.05. Results: The prevalence of Internet Addiction was found to be 27.5%. Interns showed the highest mean Internet Addiction (57.91±10.71) score. The proportion of addicted students was higher in males, 74 (31.4%), than in females, 150 (26%). The mean scores for individual domains were overuse (16.31±3.64), non-restraints (7.77±2.66), inhibiting the flow of life (9.52±3.05), emotional state (11.25±2.86), and dependence (10.47±2.53). A correlation coefficient (Spearman’s rho value of -.167) indicates a negative correlation between internet addiction and academic scores, which was statistically significant (p=0.001). Conclusion: This study revealed that internet use for varying purposes eventually leads to addiction and affects students’ academic performance. The affected students need early intervention and control over internet usage.","PeriodicalId":134552,"journal":{"name":"Brazilian Research in Pediatric Dentistry and Integrated Clinic","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135060071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first version was tested in a sample of 42 dental students to check the understanding level of the alternatives. The final version was applied to all the students enrolled in a Brazilian Public Dental School. Construct validity was assessed through factor analysis, performed by principal components analysis and Varimax rotation and reliability by internal Cronbach’s alpha coefficient (95% CI). Wilcoxon rank sum was conducted to test for gender and Kruskall-Wallis for year comparison. Multivariate analysis relied on ordinal logistic regression modeling. Results: Factor analysis revealed five factors that possessed eigenvalues greater than 1.5 and together explained 46.88% of the total variance. Internal consistency of each factor was adequate, with Cronbach's alpha ranging from 0.65 to 0.84. ‘Examinations and grades’ (82.80%) was the highest scored item. Females presented higher rates, as well as second’s and fifth’s years students. The entering students were generally concerned with factors related to “Academic Performance”, whereas clinical year students with “Insecurity Concerning their Professional Future”.

A descriptive analysis was conducted based on 1,179 (76.9%) records of OMF injuries. Results: Most patients were male children and adolescents. Accidents (59.7%), such as falls, and interpersonal violence (18.7%), such as physical aggression, were the main etiological factors.
