Abstract

Kawat nikel titanium (NiTi) dapat menjadi salah satu pilihan bahan piranti retensi cekat selain baja tahan karat berulir jamak (multistrand), yang masih dinilai kaku dan sering ditemukan terputus akibat sifat kelelahan logam. Pada penelitian ini akan dibandingkan komposisi unsur kawat piranti retensi NiTi dengan kawat NiTi superelastic dan menganalisa sifat kelelahan logam piranti retensi NiTi. Dua kelompok sampel, piranti retensi NiTi dan NiTi superelastic diuji komposisi unsur permukaannya menggunakan mikroskop SEM-EDX. Pada piranti retensi NiTi juga diberikan penekanan berulang untuk pengujian sifat kelelahan logam. Hasil SEM-EDX pada piranti retensi NiTi ditemukan adanya unsur nikel, titanium, aluminium, oksigen, dan silikon, tetapi pada NiTi superelastic hanya ditemukan unsur nikel dan titanium. Pada piranti retensi NiTi, terlihat adanya gambaran garis halus (striation) dan defleksi paska menerima tekanan vertikal berulang. Dibandingkan dengan NiTi superelastic, pada piranti retensi NiTi ditemukan unsur aluminium dan silikon yang mungkin dapat mempengaruhi sifat bahan, seperti meningkatkan formabilitas dan resistensi terhadap oksidasi secara berurutan.

Abstract

Orthodontics plays a role in an individual’s appearance which can affect the perception of others that can vary greatly depending on their educational and social economic background. Objective: To determine if there were differences between dentist’s and non-dentist’s perceptions on facial attractiveness with normal occlusion and various types of malocclusions in Indonesian population. Methods: A cross sectional study was conducted on 80 dentists and 80 non-dentists aged 23-49 years old. The perceptions differences between groups were assessed using visual analogue scale on ten photographs for each gender that have been digitally manipulated. Mann Whitney test was used to analyze the differences. Results: Normal occlusion is the most attractive condition for dentists and non-dentists. There are significant differences between dentist’s and non-dentist’s perceptions of facial attractiveness showing normal occlusion, increased overjet, increased overbite, reduced overjet, reduced overbite, mild crowding, open bite, and reversed overjet malocclusions (p < 0.05). Whilst both groups agreed (p > 0.05) that severe and moderate crowding were the least attractive malocclusion. Conclusion: Regarding the facial attractiveness, dentist’s and non-dentist’s perceptions are significantly different for most malocclusion types. However, there is an agreement that severe and moderate crowding are the most disturbing malocclusion that have a considerable effect on facial attractiveness.

Abstract

Background: Treatment that’s being done to inhibit malocclusion when it started to develop is called interceptive orthodontic. Interceptive orthodontic treatment is performed during the mixed dentition period. Early detection for interceptive orthodontic treatment needs in the mixed dentition period can be measured by Interceptive Orthodontic Care Needs Index (ICON-I). One of the factors that can affect the need for interceptive orthodontic treatment is parent’s education level. Purpose: To find out the relationship between interceptive orthodontic treatment needs in children aged 8-11 years with parent’s education level at SDN Kenari 08 Central Jakarta. Method: Intraoral examination in children with a mouth mirror performed by a dentist using ICON-I. This type of research is analytic observational research with cross sectional research design. Result: Subjects of this research were 172 students at SDN Kenari 08 Central Jakarta. The results of the examination using ICON-I showed 82 children (47,7%) required interceptive orthodontic treatment, 17 children (9,9%) did not require orthodontic treatment, and 30 children (17,4%) needed corrective orthodontic treatment. Most of the parent’s education level was at the low level with a total of 129 people (75,0%). Based on Spearman’s correlation test, the results showed significant relationship (p = 0,008). Conclusion: The results showed that there was a significant relationship between interceptive orthodontic treatment needs with parent’s education level.

Abstract

Maloklusi merupakan masalah Kesehatan masyarakat yang dapat dicegah (Preventif) ataupun dihalangi (Interseptif). Ortodonti interseptif adalah prosedur perawatan pada periode gigi campur, untuk memperbaiki maloklusi yang mulai terjadi dan mengurangi keparahan pada periode gigi permanen. Deteksi dini terhadap perkembangan terjadinya maloklusi dan potensial prosedur perawatan ortodonti yang sederhana dapat meminimalkan atau menghilangkan perawatan ortodonti yang memerlukan biaya cukup besar. Saat masa pandemi Covid-19 seperti saat ini proses pembelajaran pada semua institusi pendidikan hampir sebagian besar masih dilakukan secara daring dan dengan adanya peraturan mengenai pembatasan kegiatan masyarakat dapat menyebabkan salah satunya adalah hilangnya kesempatan untuk melakukan pemeriksaan gigi anak secara rutin ke dokter gigi. Beberapa masalah yang ditemukan pada orang tua dan anak murid SD Muhammadiyah 06 Tebet Timur diantaranya adalah tidak adanya penyuluhan mengenai kesehatan gigi dan mulut selama masa pandemi Covid-19, dan keterbatasan orang tua untuk memeriksakan gigi anaknya secara rutin ke dokter gigi selama masa pandemi. Pengabdian kepada masyarakat telah dilakukan pada hari Sabtu tanggal 26 Maret 2022 secara daring berupa penyuluhan kesehatan gigi anak secara umum dan pelatihan deteksi dini gigi tidak teratur (Maloklusi) pada anak. Kegiatan berjalan dengan lancar dan analisis terhadap kuesioner yang diberikan untuk mengetahui prior knowledge para orang tua menunjukkan masih kurangnya pengetahuan orang tua mengenai kesehatan gigi anak dan maloklusi

Abstract

Dementia is a neurodegenerative syndrome caused by chronic and progressive disorders accompanied by a decline in brain function that affects emotions, memory, decision-making, behavior, and other brain functions, which disrupt daily activities. The increasing life expectancy in Indonesia may lead to more people experiencing dementia. Recent research reports that poor oral health, such as periodontitis and tooth loss, are linked to dementia. The elderly population tends to have worse dental and oral health compared to other age groups because most of them lack awareness of maintaining dental health due to a lack of education. Dementia is currently medically incurable, making prevention efforts essential. Poco-poco exercises involve movements similar to brain exercises and can help prevent dementia. The pandemic has led to reduced activity levels and fewer visits to dentists among the elderly. The objective is to prevent and slow down dementia, especially Alzheimer's dementia. There were 62 participants in the activity, and the material was presented in the form of PowerPoint and video. The implementation of dental health education and poco-poco exercise training proved to be effective, as there was an increase in the elderly's knowledge, shown by statistically significant differences and an increase in median values between pre-test and post-test results for the participants.

Abstract

Emergency dental issues such as throbbing toothaches, dental trauma (fractures, dislodgment from the gums), teeth pierced by orthodontic wires, and wires from dental braces causing injuries by piercing the gums, are some of the health problems that can result in prolonged suffering for those experiencing them. Every case has a different level of emergency. Although for some people it is not considered a real emergency, it is still a condition that urgently requires proper action before going to the dentist. Therefore, there is a need for increased knowledge to provide first aid before visiting a dentist. Collaborative efforts between medical professionals, alumni, and professional students from the Faculty of Dentistry at Trisakti University conducted an activity involving education for the adolescent community at the Integrated Child-Friendly Public Space (RPTRA) in Kayu Mas, East Jakarta, on March 16, 2023. Before and after the distribution of education, pre and post-tests were conducted, showing significant improvements in knowledge regarding dental emergencies. The conclusion drawn from this activity underscores the importance of knowing the initial steps to handle dental emergencies in order to receive appropriate medical care.

Abstract

Elderly are people aged 60 years or more. According to Riskesdas, the highest prevalence of tooth loss in Indonesia is in the age group over 60 years, specifically at 30.6%. Prosthodontic treatment can improve a patient's oral health, improve their masticatory and speech functions, and improve their aesthetics. However, the use of dentures requires proper care. The elderly need to be aware of how to maintain oral health and care for dentures to ensure its longevity. The purpose of this activity is to increase knowledge and change attitudes and behaviors concerning dental health care, denture care and oral hygiene in the elderly. In this activity, audio visual training techniques are applied by using powerpoint and videos as training tools to improve the retention of counseling materials by the elderly and avoid saturation. The delivery of materials is conducted using a language that is easily understood by the elderly. Based on the results of the pretest and posttest, this activity shows an increase in knowledge as well as the enthusiasm of the participants in asking questions about counseling and training related to maintaining oral health and the mouth as well as dentures. A good level of success can be achieved through this activity as it is supported by appropriate methods and good communication between the implementing team and the community.
