Abstract

Secara anatomis pulpa dan periodontal saling berhubungan. Pada keadaan tertentu bisa terjadi inflamasi di pulpa dan periodontal. Hal ini disebut dengan lesi endodontik-periodontal. Perkembangan dan progresi lesi endo-perio ini dipengaruhi oleh faktor etiologi seperti bakteri, jamur, dan virus serta faktor pendukung seperti trauma, resorpsi akar, perforasi, dan malformasi gigi. Pada lesi endo-perio diperlukan rencana perawatan yang tepat agar prognosis perawatan dari gigi tersebut dapat baik. Artikel ini bertujuan memaparkan perawatan kasus lesi endo-perio yang berhasil setelah manajemen endodontik tanpa dilakukan bedah endodontik. Seorang pasien laki-laki berusia 21 tahun datang ke RSGM dengan keluhan gigi belakang kiri bawah sakit. Gigi tersebut pernah ditumpat 1 tahun yang lalu.Pada gambaran radiograf terdapat lesi radiolusen luas pada tulang alveolar sekitar akar distal. Perawatan endodontik dilakukan dengan pergantian bahan dressing kalsium hidroksida sebanyak 3 kali. Pada kontrol bulan kedua terlihat terjadi penulangan pada bagian lesi periodontal tersebut dan pasien tidak mengeluhkan rasa sakit. Kesimpulan hasil perawatan lesi endodontik periodontal dapat dirawat dengan perawatan endodontik non bedah. ABSTRACT: Management of Nonsurgical Endodontic Treatment on A Combined Endo-period Lesion. The pulp and periodontium have anatomic interrelationships. As the tooth matures, and the root is formed, three main avenues are created between pulp and periodontal ligament, i.e. dentinal tubules, lateral and accessory canals, apical foramen. These are the pathways that may provide a means by which pathological agent pass between the pulp and periodontium, thereby creating the endo - period lesion. Etiologic factors such as bacteria, fungi, and viruses as well as contributing factors such as trauma, root resorption, and dental malformations play a significant role in the development and progression of such lesions. In the endodontic - periodontal lesion is necessary to plan appropriate dental treatment that can lead to a better prognosis. This paper presents satisfactory healing of combined endo - period lesion treatment after nonsurgical endodontic management.A 21 years man came to the Conservative Dentistry Clinic, Prof. Soedomo Dental Hospital with pain complaint on left mandible posterior tooth. One year ago, this tooth already restored with resin composite restoration.Radiographs showed an extensive radiolucent lesions on 36 bifurcations extending to the distal root. After thorough cleaning and shaping, calcium hydroxide was applied intracranial and periodically renewed up to three times. Two months after root canal obturation radiograph evaluation showed ossification at the bifurcation 36. Endodontic Periodontal lesion can be treated with nonsurgical endodontic management.

Abstract

Retainer dibutuhkan untuk membantu menstabilkan posisi gigi geligi selama proses reorganisasi jaringan periodontal berlangsung. Retainer FRC ortodonsi dikembangkan sebagai alternatif material estetika serta aman bagi pasien alergi terhadap nikel. E-glass fiber lebih sering digunakan sebagai retainer ortodonsi. Penelitian ini bertujuan untuk mengkaji pengaruh komposisi glass fiber non dental dan penambahan silane terhadap kekuatan geser FRC sebagai retainer ortodonsi. Subjek penelitian terdiri dari 9 kelompok perlakuan dengan 3 jenis glass fiber yang berbeda yaitu glass fiber non dental A (LT, Cina), B (CMAX, Cina) dan C (HJ, Cina). Masing-masing glass fiber diberi perlakuan yang bervariasi yaitu tanpa penambahan silane, penambahan silane 1x dan 2x. Subjek penelitian direndam dalam akuades dan disimpan pada suhu 37ºC selama 24 jam sebelum dilakukan uji kekuatan geser dengan menggunakan alat Universal Testing Machine. Hasil penelitian dianalisis variansi dua jalur dan post hoc Tukey untuk mengetahui perbedaan statistik masing-masing kelompok. Hasil penelitian menunjukkan bahwa glass fiber non dental A dengan penambahan 2x silane memiliki rerata kekuatan geser tertinggi (12,72±2,02 MPa) sedangkan glass fiber non dental B tanpa penambahan silane memiliki rerata kekuatan geser terendah (6,96±1,69 MPa). Terdapat perbedaan bermakna antara komposisi fiber maupun penambahan silane terhadap kekuatan geser FRC (p<0,05). Tidak terdapat perbedaan bermakna pada letak kegagalan FRC (p>0,05). Berdasarkan hasil penelitian dapat disimpulkan bahwa komposisi SiO2 dan Al2O3 yang tinggi pada glass fiber non dental serta penambahan silane dapat meningkatkan kekuatan geser FRC. The Effect of Non Dental Glass Fiber Composition and Silane Addition on The Shear Bond Strength of Fiber Reinforced Composite as An Orthodontic Retainer. Retainers are required to stabilize the position of the teeth to permit reorganization of periodontal tissue. FRC orthodontic retainer was developed as an alternative material aesthetic and safe for nickel allergic patients. E-glass fiber is commonly used as an orthodontic retainer. The purpose of this study was to assess the effect of non dental glass fiber composition and silanes addition on the shear bond strength of the FRC as an orthodontic retainer. This study consisted of 9 treatment groups with three different types of non dental glass fiber, namely non dental glass fiber A (LT, China), B (CMAX, China) and C (HJ, China). Each glass fiber was given a variation treatment, without silanes, one time and two times of silanes addition. All the samples were stored in distilled water at 37ºC for 24 hours and subsequently tested for shear strength by using Universal Testing Machine.The groups were submitted to two way ANOVA analysis of variance with Tukey post test to verify the statictical difference between groups. The results showed that a non dental glass fiber A with two times of silanes addition has the highest shear bond strength (12,72±2,02 MPa), meanwhile a non dental glass fiber B without silane addition has the lowest shear bond strength (6,96±1,69 MPa). There were significant differences between the composition of glass fiber and the addition of silane toward the shear bond strength of FRC (p<0,05). No significant differences in debonded locations of FRC (p>0,05). Based on the results of this study concluded that the composition of the high SiO2 and Al2O3 in the non dental glass fiber  and the silanes addition can increase the shear bond strength FRC.

Abstract

In office bleaching menggunakan hidrogen peroksida 40% sering memberikan efek samping berupa linu baik selama maupun setelah perawatan tersebut dilakukan. Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh waktu aplikasi dan kandungan fluor desensitizing agent pada metode in office bleaching terhadap kandungan mineral gigi. Delapan gigi masing-masing dipotong menjadi 4 bagian, 6 potong digunakan untuk pemeriksaan XRD awal. Gigi dikeringkan dalam oven suhu 50° selama 30 menit diserbuk, diambil 1 mg untuk diperiksa kandungan mineralnya dengan goniometer. Dua puluh empat potong yang lain dibagi dalam 4 kelompok perlakuan. Kelompok I: gigi diaplikasi bahan bleaching 0,5-1 mm hidrogen peroksida 40% selama 1 jam, dicuci, dikeringkan, diikuti aplikasi 0,1 ml desensitizing agent tanpa fluor (CPP-ACP) selama 30 menit, dicuci, dikeringkan. Kelompok II : gigi diaplikasi CPP-ACP 30 menit, dicuci, dikeringkan, dibleaching menggunakan hidrogen peroksida 40% selama 1 jam. Selanjutnya gigi diaplikasi CPP-ACP 30 menit lagi, dicuci, dikeringkan. Kelompok III gigi dibleaching menggunakan hidrogen peroksida 40% selama 1 jam, dicuci, dikeringkan, diikuti aplikasi desensitizing agent yang mengandung fluor (CPP-ACFP) selama 30 menit, dicuci, dikeringkan. Kelompok IV: gigi diaplikasi CPP-ACFP 30 menit, dicuci, dikeringkan, dibleaching menggunakan hidrogen peroksida 40% selama 1 jam. Selanjutnya gigi diaplikasi CPP-ACFP selama 30 menit, dicuci dikeringkan. Sesudah perlakuan, semua gigi dilakukan pemeriksaan kandungan mineral gigi dengan prosedur yang sama. Uji Mann Whitney menunjukkan penurunan mineral paling sedikit terjadi pada kelompok IV (4500). Desensitizing agent mengandung F sebelum dan sesudah perlakuan in office bleaching menunjukkan penurunan mineral paling kecil. The Effectiveness of Desensitizing Agent with and without Fluorine in Office Bleaching Method to Tooth Mineral content. Tooth sensitivity arises during or after an in-office bleaching was performed is usually overcome by using desensitizing agent with or without fluor. So far, desensitizing method applied only reduces tooth sensitivity but it had not overcome demineralization problem yet. This study was aimed to determine the influence of an application process and fluoride containing desensitizing agent in tooth mineral lossEight teeth were divided into four parts. Six specimens were smoothened using agate mortar. One mg of powder was inserted into the sample holder and mounted on goniometer heads to examine mineral content before treatment using X-Ray Diffraction (XRD). Twenty-four specimens were classified into four groups. In group I, 0,1 ml desensitizing agent without fluoride (CPP-ACP) was applied for 30 minutes after an in-office bleaching using 40% Hydrogen Peroxide was performed, while in group II, CPP-ACP was applied before and after an in-office bleaching was performed. In group III 0,1 ml fluoride containing desensitizing agent (CPP-ACFP) was applied for 30 minutes after in-office bleaching using 40% Hydrogen Peroxide was performed, while in group IV fluoride containing desensitizing agent was applied before and after an in-office bleaching was performed. Finally, all of the specimens were measured in their after-treatment mineral contain. Mann Whitney test showed that the lowest mineral lost was detected in group IV (4500). Fluoride containing desensitizing agent applied before and after an in-office bleaching effectively reduced mineral loss.

Abstract

Resin akrilik merupakan bahan yang sering digunakan dalam pembuatan basis gigi tiruan. Kelemahan resin akrilik adalah mudah patah. Salah satu cara untuk mengatasi masalah tersebut adalah dengan menambahkan polyethylene (PE) atau glass fiber. Tujuan dari penelitian ini untuk mengetahui pengaruh jenis dan volumetrik fiber terhadap kekuatan transversal reparasi plat resin akrilik. Penelitian ini menggunakan dua puluh lima plat resin akrilik kuring panas berukuran 65 x 10 x 2,5 mm. Subjek dipreparasi untuk membuat jarak 3 mm dan sudut bevel 45o. Subjek dibagi menjadi 5 kelompok, masingmasing kelompok terdiri dari 5 subjek. Kelompok 1 (kontrol) tanpa penambahan fiber, kelompok II dengan penambahan 3,7% v/v PE fiber, kelompok III dengan penambahan 7,4% v/v PE fiber, kelompok IV dengan penambahan 3,7% v/v E-glass fiber, dan kelompok V dengan penambahan 7,4% v/v E-glass fiber. Seluruh plat direndam dalam air destilasi selama satu hari pada suhu 37oC. Pengujian kekuatan transversal plat resin akrilik dengan menggunakan Universal Testing Machine dan data yang didapat dianalisis menggunakan ANAVA dua jalur dengan tingkat kepercayaan 95%. Rerata kekuatan transversal (MPa) reparasi plat resin akrilik yang diperkuat fiber: 3,7% v/v PE fiber (67,77±3,34); 7,4% v/v PE fiber (80,37±8,42); 3,7% v/v E-glass fiber (96,72±5,43); 7,4% v/v E-glass fiber (109,44±4,98); sedangkan reparasi plat resin yang tidak diperkuat fiber menghasilkan kekuatan transversal 56,27±4,7 MPa. Hasil analisis menggunakanANAVA dua jalur menunjukkan variabel jenis dan volumetrik fiber memberikan pengaruh signifikan (p<0,05), sedangkan interaksi antara jenis dan volumetrik fiber tidak berpengaruh signifikan (p>0,05). Uji post hoc Tukey menunjukkan perbedaan signifikan (p<0,05) untuk seluruh kelompok perlakuan. Penambahan E-glass fiber dalam reparasi plat resinakrilik mampu meningkatkan kekuatan transversal lebih tinggi dibandingkan dengan menggunakan PE fiber. Peningkatan volumetrik fiber dapat meningkatkan kekuatan transversal reparasi plat resin akrilik. Effect Of Type And Volumetric Fiber On Transverse Strength Of Acrylic Resin Plate Repair. Acrylic resin is the most common denture base material. A disadvantage of acrylic resin is that it is easily fractured. One way to resolve this problem is by adding polyethylene (PE) or glass fibers. The purpose of this research is to find out about the effect of type and volumetric fiber on transverse strength of acrylic resin plate repaired. The experiment involved twenty five plates of heat cured acrylic with the dimensions of 65 x 10 x 2.5 mm. The speciments were prepared to create a 3 mm gap and 45° bevel. The subjects were divided into 5 groups; each group consisted of 5. Group I (control) was without fiber reinforcement, group II reinforced with 3.7% v/v PE fiber, group III reinforced with 7.4% v/v PE fiber, group IV reinforced with 3.7% v/v E-glass fiber, and group V reinforced with 7.4% v/v E-glass fiber. All plates were soaked in distilled water for one day at 37° C temperature. The plates were tested for transverse strength with Universal Testing Machine and all data obtained were analyzed with two way ANOVA at 95% confidence level. The mean of transverse strength (MPa) of the acrylic resin plate repair reinforced with fiber: 3.7% v/v PE fiber was (67.77±3.34); 7.4% v/v PE fiber (80.37±8.42); 3.7% v/v E-glass fiber (96.72±5.43); 7.4% v/v E-glass fiber (109.44±4.98); while the transverse strength of the acrylic resin plate with no fiber reinforced was 56.27±4.7 MPa. Two way ANOVA analysis shows that type and volumetric fiber had significant effect (p<0.05), while the interaction between type and volumetric fiber had no significant effect (p>0.05). Tukey post hoc test shows significant difference (p<0.05) for all groups. The addition of E-glass fibers in the acrylic resin plate repaired increased the transverse strength higher than that with PE fibers. The increase in volumetric fibers might improve the transverse strength of the acrylic resin plate repaired.

Abstract

IL-1β level of macrophage exposed to A. actinomycetemomitans decreases after administration Curcuma Zedoaria volatile oil. Activation of interleukin-1β (IL-1β) is a key regulator of the inflammatory response. Macrophage is a phagocytic mononuclear cell that plays an important role in innate and adaptive immune response. The cytokine secreted by macrophages in response to pathogen are IL-1, IL-6, IL-12, TNF-α and chemokine. Curcuma zedoaria volatile oil may have anti inflammation effect. The aim of this study was to investigate IL-1β level of macrophage exposed to A. actinomycetemcomitans after administration Curcuma zedoaria volatile oil. The subjects were 10 male Wistar rats, which divided into two groups (treatment and control), each group 5 rats. In the treatment group, 30,6 μl/ml Curcuma zedoaria volatile oil was administered per oral for 14 days and the control group used aquabidest. In the 7th days, 100 μl A. actinomycetemcomitans in CMC 2% were applied on the anterior gingival mandible for 7 days. Rats were anesthetized in the 15th days then macrophage was collected from peritoneal. Interleukin-1β level of macrophage was measured using ELISA kit (R&D Systems, USA). Data were analyzed using t-test. The result showed IL-1β level decreased after treatment. The comparison between treatment and control was significant difference (p<0.05). It can be concluded that Curcuma zedoaria volatile oil may have anti inflammation effect through reducing the IL-1β level of macrophage.
