Background: There is a relationship between dermatoglyphic patterns and oral diseases. This study aimed to compare the rate of dermatoglyphic patterns between the caries-active group and the caries-free group. Method: The study was performed on 371 children aged 6 - 12 years at Khe Tre Town primary school, Nam Dong district, Thua Thien Hue province. The children were examined and assessed for the decayed, missing, and filled teeth index. The fingerprints of both the caries-active group and the caries-free group were recorded and then classified and compared between the two groups. Results: The frequency of whorls was found to be more in the caries-active group and the frequency of loops was more in the caries-free group. Conclusion: Dermatoglyphic patterns may be used as a non-invasive tool for screening of early dental caries and guiding future research

Background: Psychological factors such as anxiety and depression have been recognized as the etiology of temporomandibular disorders. Objectives: The study aimed to evaluate the prevalence of temporomandibular disorders in dental students and describe the state of depression and anxiety and related factors in the students with the disorders. Materials and methods: 323 students at the Faculty of Odonto-Stomatology, Hue University of Medicine and Pharmacy, were examined to detect temporomandibular disorders, using the DC/TMD axis I. Then GAD-7 and PHQ-9 questionnaires were used to screen for anxiety and depression in the group with the disorders. Results: The proportion of students with temporomandibular disorders was 38.1%, intra-articular disorders accounted for the highest rate (80.5%). The percentages of depression and anxiety among students with the disorder were 28.4% and 55.3%, respectively. 41.5% of TMD students had mild anxiety and the same proportion of students had risk of depression. Risk factors associated with depression and anxiety were economic status and excercise, respectively (p < 0.05). Conclusions: The percentage of students with temporomandibular disorders is relatively high. The majority of students with the disorders are at risk for depression and low level of anxiety. There is a link between the economic status and depression, between exercise and anxiety.
