"ABSTRAK Saat ini non-alcoholic fatty liver disease (NAFLD) merupakan penyebab terbanyak dari penyakit kronik hati pada anak dan dewasa. Penelitian terbaru memperlihatkan chemerin yang merupakan salah satu zat yang diproduksi oleh jaringan lemak memiliki andil penting pada NAFLD. Tujuan penelitian ini adalah membandingkan kadar chemerin dalam darah dibandingkan enzim transaminase dalam mendeteksi secara dini kerusakan sel hati karena non alcoholic fatty liver disease (NAFLD) pada anak dengan obesitas. Penelitian deskriptif potong lintang (n=57) dilakukan pada 2 buah sekolah di Jakarta pada anak usia 9-12 tahun dengan obesitas. Anak yang masuk kriteria penelitian dilakukan pemeriksaan ultrasonografi hati untuk mendeteksi perlemakan hati. Kedua kelompok tersebut sama sama dilakukan pemeriksan kadar enzim transaminase dan chemerin darah. Hasil dari penelitian ini di dapatkan nilai rerata chemerin pada anak yang menderita NAFLD sebesar 96,71 ng/ml sedangkan yang tidak menderita NAFLD sebesar 92,8 ng/ml dengan P= 0,463. Hal ini menunjukkan nilai rerata anak dengan NAFLD dibandingkan dengan anak tanpa NAFLD tidak terdapat perbedaan bermakna. Pada penelitian ini didapatkan pula bahwa pemeriksaan chemerin darah memiliki nilai AUC 0,52 dimana nilainya lebih rendah dibandingkan nilai AUC pemeriksaan SGOT dan SGPT yakni 0,81 dan 0,90. Hasil ini menunjukkan bahwa kadar chemerin darah tidak dapat menjadi prediktor yang lebih baik untuk mendeteksi perlemakan hati dibandingkan pemeriksaan kadar SGOT dan SGPT pada penelitian ini. Manfaat chemerin sebagai prediktor kelainan hati pada anak dengan obesitas perlu diteliti lebih lanjut. ABSTRACT Non-alcoholic fatty liver disease (NAFLD) is currently the most common cause of chronic liver disease in both adults and children. Current studies have shown that chemerin, one of the biologically active substance produced by fat tissue, may have an important role in the progression of NAFLD. The aim of this research was to study whether chemerin is able to predict liver abnormalities due to NAFLD in obese children better than serum transaminases. A cross-sectional descriptive study was conducted in 57 obese subjects 9-12 years of age at 2 elementary schools in Jakarta, Indonesia. Liver ultrasound was performed in eligible subjects to detect fatty liver, along with serum chemerin and serum transaminase tests. Mean chemerin level in NAFLD and non-NAFLD children were 96.71 ng/mL and 92.8 ng/mL (p=0.463), showing no significant difference between serum chemerin level in the NAFLD and non-NAFLD group. The area under the curve (AUC) for serum chemerin was 0.52, lower than the AUC for AST (0.81) and AST (0.90). This shows that serum chemerin is not superior in predicting fatty liver compared to serum transaminase levels in this study. The role of chemerin as a marker to predict liver abnormalities in obese children still needs to be further investigated.;Non-alcoholic fatty liver disease (NAFLD) is currently the most common cause of chronic liver disease in both adults and children.

The injection of PGE2 on buccal mucosa along with orthodontic force could accelerate orthodontic tooth movement. Nevertheless, this method also has adverse effects such as pain, over resorption of the alveolar bone and root structure. PGE2 gel to substitute the necessity of injection. Hence, the effect of PGE2 gel on the rate of tooth movement and RANKL concentration in GCF and blood serum also alveolar bone and root resorption is yet to be determined.

This study was an experimental laboratory in vitro to know the stability of PGE2 gel lyophillized and in vivo in Macaca fascicularis. PGE2 gel was applied on buccal mucosa of right canine along with orthodontic force and non- PGE2 gel on left canine on beginning, second, and fourth hour each for two minutes. Gel application, tooth movement measurement, blood sample, and GCF were done every week. Macaca euthanized, and made histology ​​ and evaluated by TRAP. PGE2 gel was made resenter paratus due to instability.

Results showed that PGE2 gel enhanced tooth movement 1.8 times, RANKL and alveolar bone resorption were greater than control and root resorption was similar to control. PGE2 gel had a good prospect as topical medication to enhance tooth movement in orthodontics."

"Latar belakang: Penyebab stunting bersifat multifaktorial, salah satu faktor risikonya adalah malnutrisi kronis akibat kurangnya asupan protein. Kurangnya asupan protein dapat menyebabkan terjadi penurunan IGF-1, yaitu salah satu faktor pertumbuhan penting dalam pembangunan sel tubuh. IGF-1 juga memiliki peran dalam perkembangan kompleks dentoalveolar, terutama pada enamel, akar gigi, dentin, ligamen periodontal, dan jaringan pulpa gigi. Perlu dianalisis apakah gangguan perkembangan kompleks dentoalveolar akibat penuruan kadar IGF-1 pada anak stunting juga mempengaruhi waktu erupsi gigi. Tujuan: Menganalisis hubungan antara kadar IGF-1 dengan waktu erupsi gigi pada anak stunting. Metode: Pencarian literatur dilakukan dengan menggunakan pedoman alur Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) pada tiga electronic database, yaitu PubMed, EBSCO, dan Scopus. Penilaian kualitas literatur dilakukan dengan menggunakan QUADAS-2. Hasil: Terdapat 5 studi yang terpilih berdasarkan kriteria inklusi dan eksklusi. Hasil temuan penelitian menunjukkan bahwa kadar IGF-1 lebih rendah pada anak stunting dibandingkan dengan kelompok anak normal. Hal ini disebabkan karena kadar IGF-1 dalam darah dipengaruhi oleh banyak faktor, di antaranya yaitu nutrisi, status gizi, dan usia. IGF-1 yang rendah pada anak stunting berpotensi menyebabkan keterlambatan waktu erupsi gigi karena mengganggu mekanisme persinyalan molekul selama erupsi gigi, seperti BMP-2, Runx-2, dan TGF-. Kesimpulan: Terdapat korelasi positif antara kadar IGF-1 yang rendah dengan erupsi gigi pada anak stunting. Ekspresi IGF-1 yang rendah dapat menyebabkan terjadinya gangguan waktu erupsi gigi karena mengganggu proses maturasi gigi.

Background: The causes of stunting are multifactorial, one of the risk factors causing stunting is chronic malnutrition due to lack of protein intake. Lack of protein intake can cause the decrease of IGF-1 level, which is one of the important growth factor supporting the growth and development of somatic cells. Furthermore, IGF-1 also has a role in the development of the dentoalveolar complex, especially enamel, tooth roots, dentin, periodontal ligament, and dental pulp tissues. It should be clarified whether the disturbances of dentoalveolar complex development due to decreased IGF-1 level in the stunted children would also affect the eruption time of the dentition. Objective: To analyze the relationship between IGF-1 level and the timing of tooth eruption in stunted children. Methods: Literature researches were done by using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines through three electronic databases, which were PubMed, EBSCO, and Scopus. Quality assessment of bias was examined using QUADAS-2 tool. Results: There were 5 selected studies based on inclusion and exclusion criteria. The results of the study showed that IGF-1 levels were lower in stunted children compared to normal children. The influencing factors of the level of IGF-1 in the blood, are nutritional status and age. Low level of IGF-1 in stunted children has the potential to cause delays in the timing of tooth eruption, by interrupting the activity of BMP-2, Runx-2, and TGF-β. Conclusion: There is a positive correlation between low IGF-1 level and the timing of tooth eruption in stunted children. Low IGF-1 expression can cause disturbances in the timing of tooth eruption because it interferes with the dental maturity process."

Background: As we get older, the possibility of tooth loss will also increase. Missing teeth in the posterior area will reduce the number of occlusal support zones and will cause changes in the masticatory function. These changes may have impact on general health and affect the quality of life. This is what ultimately makes a person need some form of care. A person's demand for health services is influenced by predisposing factors which include knowledge, attitude, and practice.

Obejctives: To analyze the relationship between oral health knowledge, attitude, and practice toward denture demand in the pre- elderly and elderly.

Methods : This research was conducted with a cross sectional design on 82 subjects aged over 45 years old who attended social services at the public health center located on Panggang Island, Kepulauan Seribu. Oral examination were performed, and interview for oral health knowledge, attitude, and practice and denture demand questionnaire were conducted. Data were analyzed using Chi-Square test.

Results: Oral health knowledge gave a statistically significant difference towards denture demand (p=0,000).

Conclusion: Oral health knowledge gave a statistically significant difference towards denture demand whilst oral health attitude and practice did not."
