Premature loss of deciduous teeth is defined as the loss of deciduous teeth before they approach the eruption of the permanent teeth. The aim of this study is to find out the relationship between premature loss of deciduous teeth and the malocclusion according to the Angle’s Classification on Elementary School students children in Cimahi. The type of this research is analytic with a cross sectional research design. The samples are 77 students (7-11 year-old). The sampling method is cluster random sampling. The result shows that the prevalence of premature loss of deciduous teeth was 36.4% and the prevalence of malocclusion is 76.62%. Base on Angle’s Classification, it is revealed that 23.4% of the population has normal occlusion. The percentage of Angle’s class I malocclusion is 45,5%, class II is 23.4% and class III is 7.8%. There is a significant relationship between premature loss of deciduous teeth and its malocclusion (p-value = 0,000). It is concluded that all the students have premature loss of deciduous teeth with malocclusion. Keywords: Premature Loss, Deciduous Teeth, Malocclusion

Anterior crossbite is a condition in which one or more of the upper front teeth are located lingually to the lower front teeth during centric occlusion. Dentistry involves close face-to-face interactions with patients, so during the COVID-19 pandemic, it has been largely suspended. Teledentistry is a solution to continue the practice of dentistry during this pandemic. This case report describes an eight-year-old insecure boy who came with a complaint that his upper left front tooth had grown behind his lower front teeth since four months ago. The patient was diagnosed with Class 1 Angle malocclusion types 1 and 3. The patient education and instructions treatment used a tongue blade via teledentistry via video call. The consideration of using this treatment is due to a not ideal condition caused by the COVID-19 pandemic. This technique was done one or two hours a day. The result was twenty-one tooth malocclusion was corrected. The result indicates by the twenty-one tooth position which has passed the mandibular incisor to the labial direction. The conclusion suggests that early treatment, in this case, is necessary to modify the growth direction to prevent further malocclusion. It is also concluded that Anterior crossbite treatment via teledentistry using a tongue blade gives significant results.

Kawat ortodontik stainless steel (SS) mengandung unsur kromium yang memiliki sifat tahan terhadap korosi sehingga banyak digunakan dalam perawatan ortodontik. Vitamin C atau asam askorbat merupakan salah satu vitamin yang dibutuhkan oleh tubuh.Vitamin C bermanfaat dalam menjaga keutuhan kolagen. Kolagen mempunyai berbagai peran penting bagi tubuh yaitu membantu penyembuhan luka, memelihara kesehatan jaringan penghubung, dan membantu melindungi sel-sel tubuh. Salah satu pengobatan terhadap defisiensi vitamin C adalah dengan mengkonsumsi vitamin C selama 7-10 hari. Vitamin C mempunyai sifat asam yang dapat menyebabkan reaksi kimia sehingga bersifat korosif dan dapat mengoksidasi logam kawat dengan cara melepaskan ion-ion yang terkandung di dalamnya. Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman kawat SS dalam larutan vitamin C terhadap pelepasan ion kromium. Metode penelitian adalah laboratorium eksperimental.. Teknik pengambilan sampel menggunakan quota sampling atau pengambilan sampel berjatah yaitu kawat SS sebanyak 10 buah. Seluruh sampel direndam di dalam larutan vitamin C sebanyak 10 ml selama satu menit dalam 7 hari. Hasil penelitian menunjukan bahwa terdeteksi pelepasan ion kromium tertinggi pada pengukuran hari keenam dalam konsentrasi rendah sebesar 0,0190 mg/l. Pelepasan ion kromium terjadi karena kawat SS mengalami oksidasi berkontak dengan vitamin C yang asam. Hasil analisis statistik uji multivariat General Linear Model-Repeated Measure (GLM-RM) menunjukan nilai signifikansi sebesar 0,476 atau p>0,05 artinya tidak terdapat pengaruh yang bermakna pada lama perendaman kawat SS dalam larutan vitamin C terhadap pelepasan ion kromium sampai pada hari ketujuh. Pelepasan ion kromium kawat SS terdeteksi dalam batas aman sehingga vitamin C aman digunakan untuk pengguna ortodontik.

Latar belakang: Rasa sakit sering terjadi selama perawatan ortodontik. Rasa sakit bukan suatu masalah yang besar, tetapi hampir 10% pasien menghindari perawatan ortodontik, karena pasien memiliki pengalaman rasa sakit. Pasien yang merasa takut akan sakit dapat langsung menghindar dari perawatan ortodontik. Tujuan: mengetahui perbedaan persepsi rasa sakit setelah aktivasi alat ortodontik lepasan pada pasien di RSGM Unjani dengan metode Visual Analog Scale (VAS). Desain penelitian: Jenis penelitian kuasi eksperimental dengan rancangan post test. Subyek penelitian adalah pasien di RSGM Unjani Cimahi sebanyak 5 orang tiap kelompok perlakuan, diambil dengan cara purposive sampling. Variabel pengaruh yakni aktivasi alat labial bow, skrup ekspansi dan C Retractor. Variabel terpengaruh yakni persepsi rasa sakit. Data hasil penelitian dianalisis dengan uji Kruskall Wallis dengan tingkat kemaknaan 0,05. Hasil: menunjukkan tidak ada perbedaan yang bermakna pada ketiga variabel yang diuji dengan p=0,439. Kesimpulan: tidak terdapat perbedaan persepsi rasa sakit setelah aktivasi alat ortodontik lepasan pada pasien di RSGM Unjani dengan metode Visual Analog Scale (VAS), terutama pada ketiga varibel yang diuji, yaitu labial bow, skrup ekspansi dan C retractor.

It is important to improve the health of rural communities, including dental and oral health. The majority of the population of Mekarsaluyu Village, Bandung Regency, West Java, have jobs in the agricultural sector and lack knowledge of health. The global pandemic of the Covid-19 virus has lasted for two years. This condition causes people to need to make several adaptations and changes in behavior, including oral dental health. The purpose of the community service is to implement the Independent Learning Campus (MBKM) program to empower the role of students. The method of implementing this community service program is through outreach activities to the community regarding natural materials from the surrounding environment to improve oral dental health in the target villages of the Mekarsaluyu Village area and evaluated using a questionnaire to 16 respondents before and after the activity. Data were analyzed using T-test dependent (p0.05). The results of community service showed that there was an increase in knowledge after the implementation of the extension indicated by (p = 0.00). Based on the above, it can be concluded that the MBKM program plays a role in changing the knowledge of the assisted village communities.
