"Latar Belakang: Kondilus mandibula sering terlibat dalam berbagai kondisi patologis seperti tumor dan cedera traumatis, dimana melibatkan kondilus mandibula sehingga memerlukan reseksi dan pengangkatannya. Ameloblastoma mencakup sekitar 14% dari semua tumor rahang dan kista dan merupakan tumor odontogenik yang prevalensinya paling tinggi di negara berkembang. Pelat rekonstruksi mandibula digunakan dalam bedah mulut dan maksilofasial untuk rekonstruksi defek mandibula. Karena mandibula memainkan peran sentral dalam fungsi dan estetika, hilangnya kontinuitas rahang dapat sangat merusak integritas rahang pasien, dan sangat mempengaruhi persepsi diri dan kepercayaan diri pasien. Saat ini, kemajuan teknologi tiga dimensi (3D) dapat digunakan untuk membuat model aloplastik untuk rekonstruksi mandibula.Tujuan Penelitian: Mengetahui dan menganalisis perbedaan perubahan posisi protesa kondilus pada pasien ameloblastoma pascareseksi disartikulasi yang menggunakan 3D Model STL dan tidak menggunakan 3D Model STL pre operasi pada kontrol 1 hari setelah operasi dan 6 bulan pascareseksi mandibula di Rumah Sakit Ciptomangunkusumo Jakarta periode 2015-2020. Metode Penelitian: 22 subjek penelitian panoramik diambil dari pasien Rumah Sakit Ciptomangunkusumo sesuai dengan kriteria inklusi dan ekslusi. Subjek penelitian dilihat perbedaan nilai rata-rata tinggi protesa kondilus antara 2 kelompok (dengan Model 3D STL dan tanpa Model 3D STL) pada 1 hari pascareseksi dan 6 bulan pascareseksi. Pengukuran dilakukan dengan menggunakan aplikasi IC Measure. Analisis data untuk melihat perbedaan nilai rata-rata letak posisi protesa kondilus antara 2 kelompok (dengan Model 3D STL dan tanpa Model 3D STL) pada 1 hari pasca reseksi dan 6 bulan pasca reseksi dilakukan dengan menggunakan Uji Dependent T.test dan Wilcoxon- Signed Rank test dan perbedaan nilai tinggi dan letak posisi protesa kondilus antara 2 kelompok (dengan Model 3D STL dan tanpa Model 3D STL) 1 hari pasca reseksi dan 6 bulan pasca reseksi dengan menggunakan Uji ANOVA.Hasil: Terdapat perbedaan ketinggian dengan nilai P sebesar P= 0,004 dan tidak terdapat perbedaan letak protesa yang signifikan secara statistik dengan nilai P sebesar P= 0,66 antara kontrol 1 hari pasca reseksi dan 6 bulan pasca reseksi dengan model 3D STL. Terdapat perbedaan ketinggian dengan nilai P sebesar P=0,005 dan tidak terdapat perbedaan letak protesa yang signifikan secara statistik dengan nilai P sebesar P= 0,76 antara kontrol 1 hari pascareseksi dan 6 bulan pascareseksi tanpa model 3D STL.Kesimpulan: tidak terdapat perbedaan ketinggian dan letak protesa pada fossa kondilus yang signifikan secara statistik antara kelompok 1 hari tanpa model STL, 1 hari dengan model STL, 6 bulan dengan model STL dan 6 bulan tanpa model STL pascareseksi disartikulasi.......Background: Mandibular condyles are often involved in various pathological conditions such as tumors and traumatic injuries, that involving the mandibular condyles that require resection and removal. Ameloblastoma accounts for approximately 14% of all jaw tumors and cysts and is the most prevalent odontogenic tumor in developing countries. Mandibular reconstruction plates are used in oral and maxillofacial surgery for the reconstruction of mandibular defects. Since the mandible plays a central role in function and esthetics, loss of jaw continuity can severely impair the patient's jaw integrity, and severely affect the patient's self-perception and self-confidence. Currently, technological advances in three-dimensional (3D) models can be used to create alloplastic models for mandibular reconstruction. Aim: To know and analyze the differences in the position changes of the condylar prosthesis in ameloblastoma patients after disarticulation resection using the 3D STL model and not using the 3D STL model preoperatively in controls 1 day after surgery and 6 months after mandibular resection at Ciptomangunkusumo Hospital, Jakarta. 2015-2020 period. Methods: 22 panoramic research subjects were taken from Ciptomangunkusumo Hospital patients according to the inclusion and exclusion criteria. Research subjects saw the difference in the average height of the condylar prosthesis between the 2 groups (with 3D STL model and without STL 3D model) at 1 day post-resection and 6 months post-resection. Measurements are carried out using the IC Measure application. Data analysis to see the difference in the average value of the position of the condylar prosthesis between the 2 groups (with 3D STL Model and without 3D STL Model) at 1 day post-resection and 6 months post-resection was carried out using the Dependent T.test and Wilcoxon-Signed Rank Test. The difference in the height and position of the condylar prosthesis between the 2 groups (with 3D STL model and without STL 3D model) 1 day after resection and 6 months after resection using the ANOVA test.Result: There was a difference in height with a P value of P = 0.004 and there was no statistically significant difference in location with a P value of P = 0.66 between controls 1 day post-resection and 6 months post-resection with the 3D STL model. There was a difference in height with a P value of P = 0.005 and there was no statistically significant difference in the location of the protest with a P value of P = 0.76 between controls 1 day post-resection and 6 months post-resection without the 3D STL model.Conclusion: There was no statistically significant difference in height and position of the prosthesis between controls 1 day post-resection and 6 months post-resection without 3D STL model, there was no statistically significant difference in height and position of the prosthesis between controls 1 day post-resection and 6 months post resection with 3D STL model."

"Latar Belakang: Kekuatan gigit merupakan salah satu indikator status fungsional dalam sistem pengunyahan yang diperankan oleh gerakan otot-otot pengunyahan pada proses biomekanik kraniomandibula. Pengukuran nilai kekuatan gigit dapat menggambarkan status fungsional sistem pengunyahan pada individu yang dihasilkan oleh gerakan otot-otot rahang pada proses biomekanik kraniomandibular. Tindakan reseksi mandibula yang disebabkan kondisi patologis dapat menurunkan nilai kekuatan gigit pascaoperasi dengan cara menghasilkan ketidakseimbangan pada otot-otot pengunyahan, gerakan mandibula dan penurunan tekanan kunyah. Prosedur rekonstruksi diperlukan untuk mengembalikan fungsi menelan, fungsi bicara dan fungsi kunyah yang dapat dinilai dari kekuatan gigit. Tujuan Penelitian: Mengetahui perbedaan nilai kekuatan gigit pascareseksi rekonstruksi menggunakan vascular fibula graft, pelat rekonstruksi dibandingkan dengan nilai kekuatan gigit subyek normal di Rumah sakit Ciptomangunkusumo Jakarta Periode 2015-2020. Metode Penelitian: 45 subjek penelitian diambil dari pasien Rumah Sakit Ciptomangunkusumo. Setelah dilakukan informed consent, subjek penelitian dibagi menjadi 3 kelompok, yaitu kelompok kontrol, kelompok vascular fibula graft dan kelompok pelat rekonstruksi. Subjek penelitian diukur kekuatan gigit menggunakan alat bite force meter sebanyak 3 kali dan diambil nilai tertinggi. Data kekuatan gigit selanjutnya diuji statistik menggunakan Oneway Anova. Hasil: Terdapat perbedaan bermakna nilai kekuatan gigit antara kelompok kontrol (535.1N), kelompok vaskular fibula graft (241.8N) dan kelompok pelat rekonstruksi (148,9N) dengan nilai Sig.0.000 (p<0.05) pada uji Oneway Anova. Nilai kekuatan gigit dipengaruhi oleh jenis kelamin pada kelompok kontrol Sig.0.015 (p<0.05), dan tipe defek mandibula pada kelompok vaskular fibula graft Sig 0.009 (p<0.05). Kesimpulan: Terdapat perbedaan nilai kekuatan gigit pascareseksi dan rekonstruksi mandibula dibandingkan dengan nilai kekuatan gigit subjek normal di Rumah sakit Ciptomangunkusumo Jakarta Periode 2015-2020.......Background: Bite force is an indicator of functional status of the masticatory system, which is controlled by the movement of the masticatory muscles in the craniomandibular biomechanical processes. The measurement of the bite force value can describe the functional status of the masticatory system in individuals produced by the movement of the jaw muscles in the craniomandibular biomechanical processes. Mandibular resection caused by pathological conditions can reduce the value of postoperative bite force due to imbalances in the masticatory muscles, mandibular movement, and a decrease in masticatory load. Reconstructive procedures are needed to restore swallowing, speech and chewing functions which can be assessed by the bite force. Aim: To investigate the differences of the bite force values post mandibular resection reconstructed with vascular fibula grafts, reconstruction plate, and of normal subjects at Ciptomangunkusumo Hospital, Jakarta in 2015-2020. Methods: 45 research subjects were recruited from Ciptomangunkusumo Hospital patients according to the inclusion and exclusion criteria. After informed consent, the research subjects were divided into 3 groups, namely the control group, the vascular fibula graft group, and the plate reconstruction group. The bite force values of the research subjects were measured three times using a bite force meter, and the highest value was taken. The bite force data was then statistically compared using Oneway Anova. Results: Significant differences were found in the bite force values between the control group (535.1N), the fibula graft vascular group (241.8N) and the plate reconstruction group (148.9N) with a Sig. 0.000 (p<0.05) value in Oneway Anova test. The value of the bite force was influenced by sex in the control group Sig.0.015 (p<0.05), and the type of mandibular defects in the vascular fibula graft with Sig.0.009 (p<0.05). Conclusion: Statistically significant differences were found in the value of the bite force post resection and reconstruction of the mandible compared to that of normal subjects at Ciptomangunkusumo Hospital, Jakarta in 2015-2020."

Metode: Periodontitis diinduksi dengan injeksi LPS konsentrasi 200mg, 500mg, dan 750mg dalam 200ml larutan saline ke dalam gingiva mandibula tikus Wistar pada regio papilla interdental antara gigi insisif mandibula. Tikus Wistar dibunuh pada hari ketujuh, kemudian mandibula didiseksi dan jaringan lunak dipisahkan dari jaringan keras untuk dilakukan pengamatan dengan Stereomikroskop. Hasil: Kerusakan tulang terbesar terjadi pada injeksi LPS konsentrasi 200mg dalam 200ml larutan saline dengan rata-rata penurunan tinggi tulang yaitu 2,243mm. Kesimpulan: Injeksi LPS dengan konsentrasi 200mg dalam 200ml larutan saline pada jaringan periodontal regio anterior mandibula tikus Wistar dapat menyebabkan kerusakan tulang alveolar dan dapat menjadi acuan untuk pembuatan model periodontitis yang terstandar.

ABSTRACTBackground Periodontitis is a chronic inflammatory disease of the periodontium that remains a major problem in the field of dentistry. Periodontitis can cause progressive destruction of gingival tissue, periodontal ligament, and alveolar bone, which is clinically characterized by loss of gingival attachment and alveolar bone height reduction. Therefore, a simple, standardized, and controlled model of periodontitis is required for a preventive and therapeutic approach to overcome this problem. Lipopolysaccharide LPS has been shown to induce the occurrence of standardized periodontitis. Aim To create a model of alveolar bone destruction periodontitis in mandibular anterior region of Wistar rat which is simple, standardized, and controlled. Methods Periodontitis was induced by injection of 200 g, 500 g, and 750 g LPS in 200 l saline solution into mandibular gingiva of Wistar rat in the interdental papilla region between the mandibular incisors. Wistar rats were killed on the seventh day, then the mandible was dissected and the soft tissue was separated from the hard tissue for Stereomicroscopic observation. Results The highest bone loss occurred at injection of 200 g LPS in 200 l saline solution with an average height of bone loss is 2.243mm. Conclusion Injection of 200 g LPS in 200 l saline solution into the periodontal tissue of mandibular anterior of Wistar rat may cause alveolar bone destruction and may be used as a reference to make a standardized model of periodontitis."
