Abstract

Polyamide resin is widely used in dentistry as a denture base material. Cinnamon burmanii has been proven to have antibacterial and antifungal substances. Therefore, it is the potential to be used as a nature denture cleanser. This study aimed to examine the effect of soaking 50% cinnamon extract solution on the surface roughness of polyamide resin. This study used 16 polyamide resin samples soaked in 50% cinnamon extract solution and 16 samples soaked in distilled water as the control group. It examined the surface roughness before and after immersion for four days and seven days. Data were analyzed using paired T-test and independent T-test. The results showed a significant difference in the surface roughness of polyamide resin before and after immersion in cinnamon solution for four days and seven days. The surface roughness change is due to the polyphenol's reaction on the polyamide resin surface, which has destroyed the polymer chain of polyamide resin. DOI : 10.54052/jhds.v1n2.p165-174

Abstract

ABSTRACT The temporomandibular joint is called temporomandibular disorder (TMD) and it can be characterized by pain, limited mouth opening, masticatory disorders, joint sounds (clicking or tapping sound), crepitus, tinnitus, and persistent headache. The causes of temporomandibular joint disorders are multifactorial. The most common occurrences of these disorders are tooth loss, bad habits are bruxism, chewing on one side, and leaning on the chin. This study aimed to determine the relationship between one-sided chewing habits and the incidence of temporomandibular joint disorders in students of the Faculty of Medicine and Faculty of Dentistry, batch 2020. This research was an analytic study with a cross-sectional approach. The data were analyzed using the chi-square test with 245 research subjects from the Faculty of Medicine and the Faculty of Dentistry, batch 2020. This study used a questionnaire in the form of a g-form which was adapted from the AAOP questionnaire and distributed to all students of Jenderal Achmad Yani University Batch 2020. The results of this study found that 168 students (88.89%) have the habit of chewing on one side and the symptoms of temporomandibular joint disorders with a value of p = 0.021. It can be concluded that in this study, there is a relationship between one-sided chewing habits and symptoms of temporomandibular joint disorders. DOI : 10.54052/jhds.v2n2.p279-302
