Enterococcus faecalis adalah bakteri yang paling banyak terdapat pada infeksi saluran akar yang telah dirawat endodontik. Chlorhexidine mempunyai daya anti bakteri spektrum luas dan telah digunakan dalam endodontik sebagai bahan irigasi maupun medikasi intrakanal. Chlorhexidine mempunyai efek bakterisidal dan fungisidal karena chlorhexidine diserap ke dalam permukaan sel bakteri dan menyebabkan rusaknya integritas sel membran. Kalsium hidroksida digunakan karena mempunyai keuntungan seperti biokompatibel, bahan antimikroba dengan efek pH yang tinggi dan stimulasi jaringan keras. Campuran kalsium hidroksida dan chlorhexidine digunakan untuk alternatif melawan bakteri Enterococcus faecalis. Tujuan dari laporan kasus ini adalah untuk melaporkan kesuksesan perawatan saluran akar ulang pada gigi incisivus sentral kiri maksila dengan periodontitis periapikal akut menggunakan kombinasi kalsium hidroksida dan chlorhexidine sebagai medikamen intrakanal. Seorang pasien wanita 24 tahun datang dengan keluhan gigi insisivus sentral kiri atas yang terasa sakit sejak 4 tahun yang lalu. Gigi terasa sakit saat diperkusi, namun palpasi dan mobilitas normal. Gigi tersebut mengalami trauma dan patah 6 tahun yang lalu dan telah dilakukan perawatan endodontik. Pemeriksaan radiografi menunjukkan obturasi gigi 21 yang tidak hermetis dengan radiolusensi di periapikal dengan batas difus, pelebaran ligamen periodontal dan terputusnya lamina dura. Perawatan berupa perawatan saluran akar ulang menggunakan kombinasi kalsium hidroksida dan chlorhexidine sebagai medikamen intrakanal. Root canalretreatment dengan cleaning dan shaping ulang yang baik dengan menggunakan medikasi intrakanal berupa kombinasi kalsium hidroksida dan chlorhexidine 2% diharapkan mempunyai efek antimikroba yang sinergis untuk mencapai kesuksesan root canal retreatment. Root Canal Retreatment Using Calcium Hydroxide as Intra Canal Medicament On The Maxillary Left Incisor. Enterococcus faecalis bacteria is most abundant in the root canal infection treated endodontically. Chlorhexidine has a broad antibacterial spectrum and has been used as an endodontic irrigant and intracanal medication. Chlorhexidine has a bactericidal and fungicidal effect as chlorhexidine absorbed into the bacterial cell surface and cause damage to the integrity of the cell membrane. Calcium hydroxide is a biocompatible, antimicrobial agents with high pH effects and stimulates hard tissue formation. A mixture of calcium hydroxide and chlorhexidine is used to control bacteria Enterococcus faecalis alternative. The purpose of this case report is to report on the success of root canal treatment in the left maxillary central incisor with acute periapical periodontitis using a combination of calcium hydroxide and chlorhexidine as intracanal A 24 years old female patient presents with left upper central incisor tooth ache since 4 years ago. The tooth was hurt to percussion, but normal to pulpation as well as the mobility. The tooth has a history of previous trauma and broken 6 years ago and has performed endodontic treatment. Radiographic examination showed obturation teeth 21 are not hermetic with periapical radiolucency in diffuse boundaries, widening of the periodontal ligament and the dissolution of the lamina dura. Root canal re-treatment using a combination of calcium hydroxide and chlorhexidine as intracanal medicaments were performed. In conclussion, the root canal cleaning and shaping retreatment can be performed using a combination of calcium hydroxide and chlorhexidine as intracanal medication.

Menurunkan Biomarker Migren Secara Cepat dengan Terapi “Assisted Drainage” (Studi Eksperimental pada Hewan coba) Haryono Utomo

Publisher : Faculty of Dentistry, Universitas Gadjah Mada

Migren merupakan gejala nyeri kepala rekuren yang paling sering dikeluhkan dalam dunia medis. Di Amerika Serikat, lebih dari 30 juta orang menderita satu atau lebih nyeri kepala migren dalam setahun. Berdasarkan literatur, migren merupakan komorbiditas rinosinusitis dan asma serta melibatkan saraf trigeminus. Tatalaksana migren dalam bidang kedokteran adalah obat-obatan dan tindakan invasif seperti injeksi atau operasi pada saraf. Sangat menarik bahwa menurut laporan kasus telah dibuktikan bahwa migren berhubungan dengan gingivitis karena suatu perawatan periodontal non invasif yang disebut sebagai terapi “assisted drainage” (ADT) dapat mengurangi gejala migren dalamhitungan menit. Terapi tersebut berupa masase sulkus gingiva dalam 3 menit dengan sisi tumpul scaler manual sampai timbul keluarnya darah secara pasif. Akan tetapi mekanisme kejadian pengurangan gejala migren setelah ADT masih belum jelas. Tujuan penelitian adalah untuk verifikasi pengaruh ADT terhadap penurunan biomarker migren tikus nonalergidan alergi yang gingivitis. Tikus Wistar dibagi menjadi dua kelompok secara acak, penelitian dengan control series design study. Kelompok perlakuan adalah tikus alergi yang diinduksi dengan ovalbumin (OVA) dan non-alergi, kelompok ini disuntik dengan lipopolisakarida Porphyromonas gingivalis. Kelompok kontrol positif adalah tikus alergi, kontrol negatif dengan phosphate buffered saline (PBS). Pada beberapa kelompok dilakukan ADT. Ekspresi substans P (SP), leukotrien C4 (LTC4) dan TNF α pada gingiva dan hidung diperiksa dengan imunohistokimia peroksidase. Analisis statistik dengan ANOVA. ADT menurunkan ekspresi SP, LTC4 dan TNFα dengan sangat bermakna (p<0.05) setelah 30 menit dilakukan ADT. Kesimpulan yang didapatkan dalam riset ini adalah ADT dapat mengurangi biomarker migren dalam hitungan menit sehingga dapat diusulkan sebagai terapi ajuvan dalam tatalaksana migren. Rapid Decrease in Migraine Biomarkers with Assisted Drainage Therapy (Experimental Study In Animal model). Migraine is a recurrent headache symptom which is most often suffered in medical community. In the USA, more than 30 million people suffered one or more migraine headaches in one year. According to literature, migraine has comorbidity with rhinosinusitis and asthma involving the trigeminal nerve. Migraine management in medicine is drugs as well as invasive procedures such as trigeminal nerve injection and surgery. Interestingly, case reports revealed that migraine is also connected with gingivitis since a non-invasive periodontal treatment so called “assisted drainage” therapy (ADT) is able to reduce migraine within minutes. It is a gingival sulcus massage for 3 minutes using the blunt side of manual sickle scaler until blood oozes passively. Nevertheless, the mechanism for how ADT reduces migraine is still unclear. The objective of the research is to verify the mechanism for how ADT decreases migraine biomarkers in non-allergic and allergic rats with gingivitis. Two groups of Wistar rats were randomly selected with control series design study. The treament groups were ovalbumin-induced allergic rats and non-allergic rats injected with Porphyromonas gingivalis lipopolysaccharides. The control groups were allergic rats as positive control, and negative control injected with phospate buffered saline (PBS). In several groups, ADT was conducted. Substance P (SP), leukotriene C4 (LTC4) and TNFα expressions in gingiva and nose were examined with peroxidase immuohistochemistry. The statistical analysis was conducted with ANOVA. ADT significantly decreased SP, LTC4 and TNF-α expressions (p<0.05). ADT was ableto decrease migraine biomarkers within minutes, therefore it can be proposed as an ajuvant in migraine management.

The loss of eyeballs may lead to problems in function, psychology, and aesthetics. One of rehabilitative treatments for this case is by making prosthesis eyes. The purpose of this treatment is to heal the physical and psychological function quickly and to fix the aesthetics. A 50-year-old male patient who came to RSGM Prof. Soedomo FKG UGM’s Prostodontia Clinic complained that he lost his right eye because of traumatic injury 3 years ago. After checking the eye socket up, it was found that his conjunctiva lining was healthy, and there was no infection. The treatment plan was to make non-fabricated ocular prosthesis from acrylic resin. For the treatment procedure, the steps are as follow: minting the individual eye by using minted spoon and pouring the minting result of the eye by two phases; making the model of wax sclera followed by trying on the wax sclera pattern to the patient eye socket and making an acrylic version of sclera followed by trying on the acrylic sclera to the eye socket, and then determining the location and iris diameter to draw the iris and pupil. The finishing process of the eye prosthesis is by inserting the eye prosthesis to the patient eye socket. The checkup is needed to know the retention, stabilization and fitting the eye prosthesis. After medical check-up during a week, the eye prosthesis showed the good result, absence of pain and inflammation. The patient was more confident psychologically and comfortable using this eye prosthesis because the shape was compatible with the eye socket. Using eye prosthesis can improve the patients’ confidence as they can be accepted in social life.

Frame Partial Denture as a Supportive Therapy for Periodontal Health. Partial denture is very important in maintaining periodontal health and maintaining the stability of the remaining teeth. The fabrication of denture is an important phase in comprehensive periodontal health therapy, so as to maintain the periodontal health. Removable partial dentures should be designed to reduce the accumulation of food residue and plaque on the teeth and gingival edge of the abutment. The selection of metallic materials as denture in case of periodontal compromise can help in preventing tooth movement and maintain the position of the teeth after periodontal treatment because the nature of metal is more rigid when compared with other materials, so that the success of the treatment can be achieved. Making good metal framework denture and good cooperation between all members of the medical team in handling the case will result in a successful treatment. The aim of the study is to enrich the knowledge for periodontists and prosthodontists in using metal removable prothesis in compromised periodontal patients. Providing information and educating patients in maintaining the cleanliness of denture and mouth are also an important factor that determines the success of the manufacture of dentures.

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.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.

Keberadaan kista dapat menghambat perawatan ortodontik konvensional yang diberikan pada pasien. Tujuan artikel ini adalah menyajikan laporan kasus perawatan ortodontik alternatif seorang pasien perempuan berusia 17 tahun dengan kondisi gigi atas berjejal berat dan kista jinak di antara gigi insisivus lateral dan kaninus kiri atas. Setelah menetapkan diagnosis ortodontik, perawatan pertama yang dilakukan adalah pengangkatan kista. Kista dikirim untuk biopsi dan didiagnosis sebagai kista jinak. Orang tua dan pasien memutuskan untuk mencabut gigi insisivus lateral atas setelah mengetahui bahwa gigi insisivus lateral kiri atas nekrosis. Setelah gigi dicabut, bracket ortodontik dipasang di gigi bawah pasien. Tiga bulan kemudian, bracket ortodontik dipasang di gigi atas pasien. Kondisi gigi atas yang berjejal terkoreksi dan kaninus atas menggantikan posisi insisivus lateral. Saat ini, perawatan aktif masih dilanjutkan dan terpasang bracket ortodontik dengan elastik kelas III pada pasien. Kesimpulan artikel ini adalah pendekatan perawatan ortodontik inkonvensional dapat menjadi pertimbangan ketika ditemukan hambatan seperti adanya kista. Pasien dan orang tua harus diberi informasi mengenai konsekuensi perawatan sebelum perawatan dimulai.Unconventional Orthodontic Treatment for Upper Teeth Crowding with Benign Cyst. The presence of a cyst can provide an obstacle to the conventional orthodontic treatment given to the patients. The purpose of this article is to describe a case report of a seventeen year-old girl with a severe crowding of maxilla and presence of benign cyst between lateral incisor teeth and upper left canine treated with an alternative orthodontic treatment plan. After orthodontic diagnosis, the first treatment to be conducted was the removal of the cyst. The cyst was sent for biopsy and diagnosed as non-malignant cyst. The patient and her parents decided to extract upper laterals incisor tooth after knowing that the upper left lateral incisor tooth was necrotic. After the extractions, orthodontic brackets were bonded on the mandible. Then three months later the maxilla was bonded. The upper crowding of teeth condition was resolved very promptly and the upper canines were used to replace the laterals incisor position. Currently, active treatment is still in progress, and the patient has full upper and lower orthodontic brackets with class III elastics. After the treatment so far, it can be concluded that unconventional orthodontic treatment is worth considering when an obstacle such as a cyst is present. Patients and parents must be informed about the consequences of the treatment before active treatment is started.

Deformasi slot braket Stainless Steel akan mempengaruhi gaya yang diaplikasikan kepada gigi.Tujuan penelitian adalah untuk mengetahui deformasi slot braket dari lima merek braket yaitu 3M, Biom, Versadent, Ormco dan Shinye akibat gaya torque kawat Beta Titanium 0.021x0.025 inci dengan sudut puntir 45° dan besar gaya torque dengan sudut puntir 30° dan 45°. Penelitian juga bertujuan untuk membandingkan deformasi dan besar gaya torque antara kelima merek braket. Penelitian dilakukan pada 50 braket Stainless Steel Edgewise dari lima kelompok merek braket (n=10) dilem ke akrilik. Masing-masing braket dilakukan dua tahapan pengukuran yaitu pengukuran deformasi braket dengan menghitung rerata tinggi slot braket dengan mikroskop stereoskopi sebelum dan sesudah uji torque dan pengukuran besar gaya torque dengan alat uji torque. Hasil analisa statistik menunjukkan terdapat deformasi slot braket pada kelima merek braket dengan deformasi permanen secara klinis pada braket Biom (2,79 µm) dan Shinye (2,29 µm). Besar gaya torque pada kelima braket dari yang paling besar yaitu 3M, Ormco, Versadent, Shinye dan Biom. Perbandingan deformasi slot braket dan besar gaya torque antara kelima braket adalah terdapat perbedaan deformasi slot braket antara kelima merek braket kecuali antara 3M dan Ormco dan Biom dan Shinye dan terdapat perbedaan besar gaya torque antara kelima braket dengan sudut puntir 30° (kecuali 3M dan Ormco) dan 45°. Kesimpulan, Komposisi logam dan proses pembuatan braket merupakan faktor yang mempengaruhi terjadinya deformasi slot braket dan besar gaya torque. Proses pembuatan dengan metode MIM dan komposisi logam AISI 303 dan 17-4PH menurunkan risiko deformasi.Slot Deformation in Various Stainless Steel Bracket Products due to The Torqueing Force of Beta Titanium Wire. Stainless Steel bracket slot deformation affects force applied to teeth. The research aims to determine slot deformation of five different bracket brands namely, 3M, Biom, Versadent, Ormco and Shinye due to torque of Beta Titanium wire 0.021 x 0.025 inch with torsional angle of 45° and the amount of torque with torsional angle of 30° and 45°. The research also attempts to compare the deformation and amount of torque among all five bracket brands. Fifity Stainless Steel Edgewise brackets from five bracket group brands (n=10) were attached on acrylic. Bracket slot measurement was carried out in two stages: firstly, deformation measurement by calculating average bracket slot height with stereoscopy microscope before and after application of torque; and secondly, measurement of torque with a torque measurement apparatus. Statistical analysis showed that there are slot deformations on the five bracket brands with clinical permanent deformation on Biom (2,79 µm) and Shinye (2,29 µm). The amount of torque on the five bracket brands from the highest is 3M, Ormco, Versadent, Shinye and Biom. From correlation assessment between bracket slot deformation and amount of torque in the five brands, a difference is found in the deformation in five brands except 3M, Ormco, Biom and Shinye. There is a difference in the amount of torque between the five brands with torsional angle of 30° (except 3M and Ormco) and 45°. It is concluded that metal compositions and manufacturing process are the factors that influence the occurrence of deformation bracket slot and the amount of torque. Manufacturing process using MIM and metal compositions of AISI 303 and 17-4 PH reduce the risk of deformation.
