"Latar Belakang: Kejadian stunting di Indonesia masih tergolong tinggi jika dibandingkan dengan standar yang ditetapkan oleh World Health Organization (WHO). Menurut beberapa penelitian terdahulu, stunting dapat menyebabkan kelainan email dan keterlambatan erupsi gigi permanen. Telah dilaporkan adanya hubungan antara status gizi stunting dengan penurunan kadar IGF-1, serta hubungan antara kadar IGF-1 dengan pertumbuhan gigi terkait dengan perkembangan email dan erupsi gigi. Pengukuran kadar IGF-1 biasanya dilakukan dengan menggunakan IGF-1 darah. Diketahui bahwa saliva mengandung biomarker yang terkandung di dalam darah, termasuk IGF-1, dalam kuantitas yang lebih rendah. Tujuan: Menganalisis hubungan antara kadar IGF-1 saliva dengan kelainan email dan waktu erupsi gigi pada anak stunting usia 6-8 tahun. Metode: Penelitian ini merupakan penelitian observasi laboratorium dengan menggunakan 40 sampel saliva yang diambil dari sediaan biologis tersimpan dari penelitian tahun 2019 pada populasi siswa/i sekolah dasar (SD) kelas 1-2 Kecamatan Nangapanda, Ende, Nusa Tenggara Timur yang telah dikelompokkan berdasarkan status gizi stunting dan normal. Sampel saliva diuji menggunakan ELISA kit human IGF-1 untuk melihat kadar IGF-1. Kelainan email dinilai dengan cara menghitung jumlah gigi yang mengalami kelainan pada mahkota serta waktu erupsi gigi dinilai dengan menghitung jumlah gigi permanen yang telah erupsi. Data kemudian dianalisis dengan menggunakan program SPSS. Hasil: Kadar IGF-1 saliva pada anak status gizi normal 7,50 ng/ml dan pada anak stunting 5,64 ng/ml. Proporsi IGF-1 terhadap total protein pada anak status gizi normal 1,04×10-2 dan pada anak stunting 8,96×10-3. Rata-rata jumlah gigi yang mengalami kelainan mahkota pada anak berstatus gizi normal 2,94 gigi dan pada anak dengan status gizi stunting 1,17 gigi. Terdapat perbedaan yang signifikan pada jumlah gigi dengan kelainan mahkota antara anak bestatus gizi normal dan stunting (p < 0,05). Rata-rata jumlah erupsi gigi permanen pada anak berstatus gizi normal 8,29 gigi dan pada anak stunting adalah 8,04 gigi. Tidak terdapat perbedaan signifikan jumlah erupsi gigi permanen antara anak berstatus gizi normal dan berstatus stunting (p > 0,05). Terdapat korelasi positif lemah yang tidak signifikan antara kadar IGF-1 dengan status gizi anak usia 6-8 tahun (r = 0,147), korelasi positif lemah yang tidak signifikan antara kadar IGF-1 dengan jumlah kelainan mahkota gigi anak usia 6-8 tahun (r = 0,219), terdapat korelasi positif lemah yang tidak signifikan antar kadar IGF-1 dengan jumlah erupsi gigi permanen anak usia 6-8 tahun (r = 0,074). Kesimpulan: Pada anak stunting usia 6-8 tahun yang secara tidak signifikan memiliki kadar IGF-1 saliva lebih rendah dan waktu erupsi lebih lambat dibandingkan anak normal tetapi erlihat frekuensi kelainan email yang lebih tinggi. Pada kelompok sampel demikian, tidak terlihat hubungan antara kadar IGF-1 saliva dengan kelainan email dan keterlambatan waktu erupsi gigi permanen.

Background: The incidence of stunting in Indonesia is still relatively high when compared to the standards set by the World Health Organization (WHO). According to several previous studies, stunting can cause enamel defects and delayed tooth eruption. It has been reported that there is a relationship between stunting nutritional status and decreased IGF-1 levels, as well as a relationship between IGF-1 levels to enamel development and tooth eruption. Measurement of IGF-1 levels is usually done using serum IGF-1. Saliva contains biomarkers that is circulating in the blood, including IGF-1, but in much lower quantities. Objective: Analyzing the relationship between IGF-1 levels in saliva with enamel defects and the time of tooth eruption in stunted children aged 6-8 years. Method: This research was a laboratory observation study using 40 saliva samples taken from stored biological samples from a 2019 study on a population of elementary school students class 1-2 Nangapanda District, Ende, East Nusa Tenggara which has been grouped based on stunting and normal nutritional status. Saliva samples were tested using the human IGF-1 ELISA kit to see the levels of IGF-1. Enamel defects were assessed by counting the number of teeth with crown defects and the time of tooth eruption was assessed by counting the number of erupted permanent teeth. The data were then analyzed using the SPSS software. Result: Salivary IGF-1 levels in children with normal nutritional status were 7.50 ng/ml and 5.64 ng/ml in stunted children. The proportion of IGF-1 to total protein in children with normal nutritional status was 1.04×10-2 and in stunted children was 8.96×10-3. The average number of teeth with crown defects in children with normal nutritional status was 2.94 teeth and in stuntedchildren was 1.17 teeth. There was a significant difference in the number of teeth with crown defects between normal and stunted children (p < 0.05). The average number of permanent tooth eruptions in children with normal nutritional status was 8.29 teeth and in stunted children was 8.04 teeth. There was no significant difference in the number of permanent tooth eruptions in children with normal nutritional status and stunting (p > 0.05). There was a weak positive correlation that was not significant between IGF-1 levels and the nutritional status of children aged 6-8 years (r = 0.147), a weak positive correlation that was not significant between IGF-1 levels and the number of dental crown defects (r = 0.219), and a correlation between IGF-1 levels and the number of permanent teeth eruption (r = 0.074). Conclusion: Stunted children aged 6-8 years old tend to show not significant lower IGF-1 level and delayed tooth eruption compared to normal children but had significant lower frequency of enamel defect. In such samples no significant relationship between salivary IGF-1 level and tooth eruption time could be seen."

"Latar belakang: Trauma dentoalveolar merupakan salah satu cedera yang sering ditemukan dalam kasus kekerasan fisik. Namun, penilaian derajat cedera pada kasus trauma dentoalveolar dalam penulisan Visum et Repertum (VeR) masih bersifat subjektif dan belum memiliki pedoman baku. Padahal, derajat cedera menjadi pertimbangan penting dalam proses hukum, baik untuk menentukan Tingkat kerugian terhadap korban maupun beratnya sanksi bagi pelaku. Oleh karena itu, diperlukan suatu pendekatan sistematis untuk menentukan derajat cedera berdasarkan indikator medis dan hukum.Metode: Pendekatan terhadap responden menggunakan metode Delphi dengan melibatkan 15 ahli odontologi forensik dari berbagai institusi di Indonesia. Tiga indikator utama dalam penilaian derajat cedera trauma dentoalveolar, yaitu disfungsi fisiologis, luas jaringan terdampak, dan jenis perawatan yang dibutuhkan, divalidasi terlebih dahulu menggunakan Content Validity Index (CVI) oleh enam ahli (Lynn, 1986), terdiri dari tiga spesialis konservasi gigi dan tiga spesialis bedah mulut maksilofasial. Proses Delphi dilakukan dalam dua putaran hingga diperoleh konsensus klasifikasi derajat cedera sesuai berdasarkan ICD-11.Hasil: Hasil uji validitas menunjukkan bahwa ketiga indikator memiliki nilai I-CVI sebesar 0,83, melebihi batas minimal 0,78 (Lynn, 1986), sehingga dinyatakan valid. Pada putaran pertama Delphi konsensus tercapai pada 12 dari 17 jenis cedera trauma dentoalveolar menurut ICD-11. Lima jenis cedera lainnya belum mencapai konsensus, sehingga dilakukan putaran kedua. Pada putaran kedua, seluruh jenis cedera mencapai konsensus, sehingga putaran ketiga tidak diperlukan.Kesimpulan: Hasil konsensus menunjukkan bahwa derajat cedera trauma dentoalveolar dapat dikategorikan ke dalam derajat ringan, sedang, dan berat berdasarkan kombinasi dari tiga indikator utama. Penentuan derajat cedera ini memungkinkan standar yang lebih objektif dan dapat diterapkan dalam penulisan Visum et Repertum kasus penganiayaan.

Background: Dentoalveolar trauma is one of the most frequently encountered injuries in cases of physical violence. However, the assessment of injury severity in dentoalveolar trauma, particularly in the preparation of the Visum et Repertum (VeR), remains subjective and lacks standardized guidelines. In fact, injury severity serves as a crucial consideration in legal processes, both in evaluating the extent of harm to the victim and in determining the severity of sanctions for the perpetrator. Therefore, a systematic approach is needed to determine injury severity based on relevant medical and legal indicators.

Methods: A Delphi method was employed to gather expert consensus, involving 15 forensic odontologists from various institutions across Indonesia. Three main indicators were used to assess the severity of dentoalveolar trauma: physiological dysfunction, the extent of affected tissue, and the type of treatment required. These indicators were first validated using the Content Validity Index (CVI) by six experts (Lynn, 1986), consisting of three specialists in conservative dentistry and three specialists in oral and maxillofacial surgery. The Delphi process was conducted in two rounds until a consensus was reached regarding the classification of injury severity based on ICD-11.

Results: The CVI analysis showed that all three indicators had an I-CVI value of 0.83, exceeding the minimum threshold of 0.78 (Lynn, 1986), and were therefore considered valid. In the first round of the Delphi process, consensus was reached on 12 out of 17 types of dentoalveolar trauma according to ICD-11. The remaining five types did not reach consensus and were included in a second round. In the second round, full consensus was achieved for all trauma types, making a third round unnecessary.

Conclusion: The final consensus demonstrates that the severity of dentoalveolar trauma can be categorized into mild, moderate, and severe based on the combination of three key indicators. This classification provides a more objective standard that can be applied in the formulation of Visum et Repertum for assault cases."

Latar Belakang: Celah bibir dan palatum merupakan kelainan kongenital yang paling sering terjadi pada regio orofasial. Pasien celah bibir dan palatum menunjukkan sejumlah permasalahan seperti defek tulang alveolar yang lebar, kehilangan gigi kongenital, supernumerary teeth, hipoplasia dan gigi impaks. Autologous alveolar bone grafting dianggap sebagai perawatan gold standard untuk rekonstruksi tulang alveolar dengan menggunakan tulang kanselus dari puncak ilium anterior. Namun, pengambilan tulang ilium bersifat invasif dan memiliki potensi terjadinya komplikasi. Mengingat hal tersebut, teknik rekayasa jaringan yang memanfaatkan scaffolds, faktor pertumbuhan, dan sel punca dipertimbangkan sebagai pilihan perawatan yang baru. Sel punca mesenkim bisa didapatkan dari jaringan pulpa, yang disebut dengan sel punca pulpa gigi sulung atau stem cells from exfoliated deciduous teeth (SHED) dan sel punca pulpa gigi permanen atau dental pulp stem cells (DPSC). Salah satu kriteria yang harus dimiliki sel punca mesenkim adalah mengekspresikan surface marker CD73, CD90, dan CD105. Pada pasien normal, penelitian yang membandingkan karakteristik antara SHED dan DPSC telah membuktikan bahwa keduanya merupakan sel punca mesenkim dengan mengekspresikan surface markersesuai dengan kriteria. Namun, pada pasien celah bibir dan palatum belum banyak diteliti. Tujuan: Menganalisis perbedaan persentase sel yang mengekspresikan surface marker (CD73, CD90, dan CD105) pada SHED dan DPSC pasien celah bibir dan palatum. Metode: Sel punca pulpa gigi sulung dan gigi permanen diisolasi dari jaringan pulpa pasien celah bibir dan palatum. Persentase sel yang mengekspresikan surface marker (CD73, CD90, dan CD105) dianalisis dengan uji flow cytometry. Hasil: Analisis flow cytometry menunjukkan bahwa baik SHED maupun DPSC mengekspresikan masing-masing surface marker dalam persentase yang tinggi (>90%). Setelah dilakukan uji Independent T-test untuk membandingkan ekspresi masing-masing surface markerpada kedua grup, didapatkan hasil >0,05. Kesimpulan:  Tidak terdapat perbedaan bermakna antara ekspresi masing-masing surface marker pada SHED dan DPSC pasien celah bibir dan palatum.

Background: Cleft lip and palate is the most common congenital anomaly in the orofacial region. Cleft lip and palate patients present with a number of complaints such as wide alveolar bone defects, congenitally missing teeth, supernumerary teeth, hypoplastic dan impacted teeth. Autologous bone grafting is considered to be the gold standard for alveolar bone reconstruction using the cancellous bone harvested from the anterior iliac crest. However, the procedure is invasive and carries a risk of complications. Bearing all that in mind, tissue engineering that utilizes scaffolds, growth factors, and stem cells arises as a new therapeutic option. Mesenchymal stem cells can be obtained from dental pulp, which are called stem cells from exfoliated deciduous teeth (SHED) and dental pulp stem cells (DPSC). One of the criterias to define mesenchymal stem cells is the expression of surface markers CD73, CD90, and CD105. In normal patients, both SHED and DPSC have been known to express those surface markers. However, the expression of CD73, CD90, and CD105 in SHED and DPSC from cleft lip and palate patients has not been fully explored. Objective: To analyze the difference in the percentage of cells that express CD73, CD90, and CD105 in SHED and DPSC from cleft lip and palate patients. Methods: SHED and DPSC were isolated from dental pulp. The expression of surface markers were analyzed with flow cytometry. Results: Flow cytometry analysis showed that SHED and DPSC from cleft lip and palate patients highly express (>90%) surface markers that are associated with mesenchymal stem cells such as CD73, CD90, and CD105. The Independent T-Test was then performed to see a comparison between the expression of each surface marker in both groups and the value was >0.05. Conclusions: There is no significant difference between the percentage of cells that express each surface marker in SHED and DPSC from cleft lip and palate patients.
