Saat ini, implant merupakan pilihan terbaik untuk menggantikan gigi yang tanggal, akan tetapi prosedur pemasangannya terbilang rumit dan memerlukan prosedur bedah kedua untuk pemasangan prostetik. Beberapa komplikasi seperti screw patah atau longgar dan adanya celah mikro pada batas pertemuan implant dan abutment dapat menyebabkan kegagalan implant. Studi kasus ini bertujuan untuk membahas mengenai keuntungan dan kerugian desain implant gigi one-piece dan two-pieces. Kasus pertama, seorang wanita berusia 43 tahun datang untuk mendapatkan perawatan implant pada region 16. Ketinggian tulang alveolar yang tersedia adalah 5 mm. Prosedur pengangkatan dasar sinus transalveolar dilakukan dengan pemberian allograft sebanyak 0,5 cc dilanjutkan dengan pemasangan implant gigi one-piece sepanjang 12 mm. Kasus kedua, seorang wanita 24 tahun datang untuk mendapatkan perawatan implant pada regio 46. Ketinggian tulang alveolar yang tersedia adalah 12 mm, kemudian dilakukan pemasangan implant gigi two-pieces sepanjang 10 mm. Implant gigi one-piece menawarkan berbagai keunggulan yaitu: hanya diperlukan sekaliprosedur bedah dan prosedur prostetik lebih sederhana. Desain ini juga meniadakan celah mikro pada perbatasan implant dan abutment. Desain implant gigi one-piece memiliki keterbatasan pada pilihan prosedur prostetik apabila dibandingkan dengan desain implant gigi two-pieces. One-Piece Versus Two-pieces Tooth Implant In Daily Practice. Implant had been a gold standard to replace missing tooth. However, implant marketed today was considered complex, and needs a second surgery. Complications may occur such as screw loosening or fracture and the presence of micro gap at implant-abutment-junction that is found causing fixture failure. The one-piece-implant design may offer some advantages. Purpose: this paper was aimed to discuss the pros and cons of one-piece-implants and two-piece-implants. Case 1 A 43-year-old woman came to place an implant on #16. The available bone height was 5 mm. A trans alveolar sinus lift procedure was performed with 0,5 cc allograft. A 12 mm one-piece-implant was inserted. Case 2 A 24-year-old woman came to place an implant on #46. The available bone height was 12 mm and a 10 mm two-piece-implant was inserted. Discussion: One-piece-implant offers some advantage. It needs no second surgery, easier placement protocol, and more natural prosthetic procedures. The design is preventing the failure in implant-abutment-junction failure. The absence of micro gap in one-piece-implant seems superior in preventing crestal bone resorption. However, the prosthetic option was limited in one-piece-implant. Two-piece-implant offers more choices in prosthetic abutment. Conclusion: One-piece-implant was easier and provide simple protocol with limited choice on prosthetic.

Mini screw orthodontics merupakan alat yang digunakan dalam perawatan ortodonsia untuk kasus yang membutuhkan absolute anchorage. Mini screw yang tersedia terbuat dari logam nikel titanium atau stainless steel yang pada beberapa pasien menyebabkan reaksi pada jaringan. Uji implantasi adalah uji yang dilakukan untuk menentukan biokompatibilitas medical device yang berkontak langsung dengan jaringan hidup. Respon jaringan terhadap jejas pasca implantasimempengaruhi derajat pembentukan jaringan granulasi, reaksi benda asing, dan fibrosis. Penelitian ini bertujuan untuk mengetahui efek lokal implantasi kobalt kromium sebagai alternatif bahan mini screw orthodontics terhadap jaringan subkutan kelinci albino. Subjek penelitian berupa 20 ekor kelinci jantan albino yang digunakan untuk 2 kelompok(perlakuan dan kontrol negatif). Kobalt kromium dibuat lempengan diameter 10 mm dan ketebalan 1 mm. Pada kelompok perlakuan, material diimplankan pada jaringan subkutan dorsum kelinci dengan insisi sampai terbentuk poket subkutan, dasar poket tidak lebih dari 10 mm dari garis awal insisi dan dilakukan suturing. Kelompok kontrol hanya dilakukanincisi kemudian disuturing. Secara makroskopis 24 jam pasca implantasi, daerah implan diamati terjadinya edema, hematoma, enkapsulasi dan tanda-tanda inflamasi. Evaluasi secara mikroskopis pada hari ke 14 pasca implantasi, diamati perubahan histopatologis infiltrasi sel-sel inflamasi, kemudian rerata hasil diuji dengan uji independent samplet-test untuk mengetahui apakah ada perbedaan jumlah sel-sel inflamasi pada kelompok perlakuan dan kontrol. Hasil pengamatan makroskopis, kelompok perlakuan maupun kontrol hanya terlihat tanda inflamasi ringan berupa eritema. Rerata dan Simpangan baku jumlah PMN, limfosit, sel plasma, makrofag, giant cell, neovaskularisasi, fibrosis kobalt kromium dan kontrol berturut turut yaitu (0,6 ± 0,49; 0,7 ± 0,48); (0,9 ± 0,87; 1,0 ± 0,67); (0,6 ± 0,24; 0,6 ± 0,21); (1,4 ± 0,84; 0,9 ± 0,74); (0,5 ± 0,27; 0); (0,6 ± 0,33; 0,7 ± 0,48); (0,5 ± 0,27; 0,1 ± 0,02). Hasil t-test menunjukkan perbedaan yang tidak signifikan (p>0,05) pada 6 parameter inflamasi sedangkan parameter giant cell menunjukkan perbedaan yang signifikan (p<0,05). Kesimpulan penelitian ini adalah implantasi subkutan logam kobalt kromium menyebabkan reaksi jaringan berupa infiltrasi giant cell selama 14 hari pasca implantasi sebagai respon tehadap benda asing. Effect Of Subcutaneous Implantation Of Cobalt Chromium As An Alternative Material For Mini Screw Orthodontics Against Albino Rabbit’s Tissue. Mini screw orthodontics is an instrument which is used in orthodontic treatment for some cases that require absolute anchorage. Available mini screws are made of nickel titanium or stainless steel alloy which in some patients may cause a reaction to the tissues. Implantation test is a test performed to determine the biocompatibility of medical devices that are directly contacted to the living tissue. Tissue response to injury after implantation affects the degree of formation of granulation tissue, foreign body reaction, and fibrosis. The aim of this study is to determine the local effect of implantation of cobalt chromium as an alternative material for mini screw orthodontic against the subcutaneous tissue of albino rabbits. The subjects of study were 20 male albino rabbits divided into two groups (treatment and negative control groups). Cobalt chromium was made in the form of discs with 10 mm in diameter and 1 mm in thickness. In the treatment group, the material was implanted in the subcutaneous tissue of the dorsum of the rabbits with an incision to form a subcutaneous pocket. The pocket base was not more than 10 mm from the initial line of incision then suturing was performed. The control group only had incision then sutured to maintain aseptic conditions. Macroscopically 24 hours after implantation, the implant area was observed related to the occurrence of oedema, haematoma, encapsulation and signs of inflammation. The evaluation on day 14 post-implantation shows the histopathologic changes observed by the infiltration of inflammatory cells types. The average of the results was analyzed using independent sample t-test. The results of the macroscopic observation shows that the treatment and control group were only seen of mild inflammatory signs included erythema. The mean and standard deviation of the amount of PMN, lymphocyte, plasma cells, macrophage, giant cell, neovascularisation, and fibrosis from cobalt chromium and control groups were (0.6 ± 0.49; 0.7 ± 0.48); (0.9 ± 0.87; 1.0 ± 0.67); (0.6 ± 0.24; 0.6 ± 0.21); (1.4 ± 0.84; 0.9 ± 0.74); (0.5 ± 0.27; 0); (0.6 ± 0.33; 0.7 ± 0.48); (0.5 ± 0.27; 0.1 ± 0.02). The results of t-test show a significant difference in giant cell (p<0.05), while the six others did not (p>0.05). The conclusion of this study is that the cobalt chromium alloy can affect the subcutaneous tissue by inducing giant cell infiltration on day 14 post-implantation as the result of foreign body reactions.

Tulisan ini melaporkan penatalaksanan fraktur kompleks zigomatikomaksilaris sinistra dengan miniplate osteosynthesis.Seorang laki-laki 22 tahun dirujuk ke Bagian Bedah Mulut RSUP Dr Sardjito dengan riwayat kecelakaan lalulintas tiga minggu sebelum masuk RS. Pasien mengeluh daerah pipi kiri terasa tebal dan dirasa lebih datar dari pipi kanan. Pemeriksaan klinis terdapat parestesi nervus infraorbita sinistra, displace tulang daerah infraorbital rim sinistra, diskontinuitas regio sinus maksilaris sinistra. Radiografis CT axial dan koronal serta CT Scan 3D tampak fraktur melibatkan infraorbital rim sinistra, fraktur sinus maksila sinistra, fraktur pada sutura zigomaticofrontalis dan pada sutura zigomatikotemporalis. Penatalaksanaannya dilakukan open reduction internal fixation (ORIF) fraktur kompleks zigomatikomaksilaris dengan miniplate osteosynthesis di bawah anestesi umum. Pasca operasi gejala parestesi berangsur- angsur berkurang, defek infraorbital rim terkoreksi dan pipi kiri tampak kembali prominen. Prognosis kasus ini dubia ad bonam. ORIF dengan miniplate osteosynthesis dapat memulihkan deformitas wajah dengan hasil malar eminensia kembali prominen dan membuat kondisi dekompresi nervus infraorbita sinistra yang mendukung proses pemulihan sensorisnya.Management of Zygomaticomaxillaris Sinistra Complex Fractures with Osteosynthesis Miniplate. Face lies in a prominent position so that this area is often susceptible to trauma. Os zygomaticum is an area that holds the heaviest impact on facial trauma. This paper reports one case about zygomaticomaxillary complex fractures management with miniplate osteosynthesis. A 22 years old man was referred to the Department of Oral Surgery Dr Sardjito Hospital with a history of traffic accident three weeks before admission. He felt that his left cheek was thick and flatter than the right one. Clinical examination found that the left infraorbita nerve was paresthesized, the bone on the left infraorbital rim region was displaced and the left maxillary sinus region was discontinued. Radiography examination using CT axial and coronal, and 3D CT scan showed both of the left infraorbital rim and maxillary sinus were fractured, as well as the zygomaticotemporalis suture and the zygomaticofrontalis suture. An Open Reduction Internal Fixation (ORIF) of the zygomaticomaxillary complex fractures with miniplate osteosynthesis was performed under general anesthesia. The result showed that the postoperative paresthesia symptoms were gradually diminished, the infraorbital rim defects were corrected and the prominent left cheek was recontructed. The prognosis was dubia ad bonam. It can be concluded that ORIF with miniplate osteosynthesis reconstructs the facial deformity, recovers the malar eminence prominency. The nerves decompression will favor the recovery process of the left infraorbita sensory

Orthodontic Treatment of Anterior Open Bite. An anterior open bite therapy has long been considered a challenge to orthodontist. The prevalence of anterior openbite range from 3,5 % to 11% among various age and ethnic groups and it has been shown that approximately 17% of orthodontic patients have open bite. Stability of treatment result of anterior open bite with well-maintained results is difficult, because the combination of anteroposteriorly discrepancy with skeletal open bite requires the highest degree of diagnostic and clinical skill. The etiology is complex, potentially involving skeletal, dental and habitual factors. The importance of an anterior open bite therapy is to eliminate the cause of the open bite. Various treatment modalities for the correction of an anterior open bite have been proposed, orthognatic surgery and orthodontic camouflage treatment such as high-pull headgear, chin cup, bite blocks, functional appliances, extractions, multi-loop edgewise arch wires and mini implant. The stability is the most important criterion in deciding the treatment method for anterior open bite malocclusion.

Inflamasi merupakan respon alami tubuh terhadap adanya kerusakan jaringan. Salah satu medikamen untuk mengatasi inflamasi adalah antiinflamasi non steroid (AINS). Penggunaan AINS mempunyai beberapa efek samping dan dalam beberapa hal penggunaan tanaman obat dinilai lebih aman. Rosela merupakan salah satu tanaman obat yang mempunyai potensi sebagai antiinflamasi. Penelitian ini bertujuan untuk mengetahui efek pemberian sistemik ekstrak etanolik rosela terhadap ekspresi COX-2 dan jumlah neutrofil fase inflamasi pada proses penyembuhan luka. Bunga rosela didapatkan dari perkebunan di Dusun Bulusari Desa Pojok Kecamatan Tarokan Kabupaten Kediri Jawa Timur. Pembuatan ekstrak rosela dilakukan di LPPT unit I UGM Yogjakarta dengan cara perkolasi. Tikus putih galur Wistar sebanyak 36 ekor diberi perlukaan dengan punch biopsi ɵ 3 mm pada mukosa bukal. Subjek dibagi menjadi 3 kelompok, masing-masing kelompok 12 ekor tikus. Pembagian kelompok terdiri dari kontrol negatif (saline), kontrol positif (ibuprofen 20 mg/kg BB) dan perlakuan (ekstrak rosela 500 mg/kg BB). Pemberian minum sesuai kelompoknya sehari sekali selama 4 hari. Pada hari ke-1, ke-2, ke-3 dan ke-4 tikus dikorbankan lalu jaringan mukosa yang mengalami perlukaan dibuat preparat histologis. Pewarnaan Hematoksilin Eosin (HE) dilakukan untuk mengamati jumlah neutrofil. Ekspresi COX-2 diamati pada preparat dengan pewarnaan imunohistokimia menggunakan rabbit polyclonal antibody COX-2 (Lab Vision, USA). Jumlah neutrofil dan ekspresi COX-2 dihitung di bawah mikroskop cahaya lalu data dianalisi menggunakan ANAVA dan LSD. Hasil penelitian menunjukkan bahwa ekspresi COX-2 dan jumlah neutrofil lebih rendah pada kelompok perlakuan dibanding kontrol. Pengamatan klinis pada hari ke-4 juga tampak luka seluruh subjek telah menutup sempurna setelah pemberian minum rosela. Disimpulkan bahwa ekstrak etanolik rosela mempunyai kemampuan menghambat ekspresi COX-2 dan menurunkan jumlah neutrofil sehingga dapat digunakan sebagai bahan anti-inflamasi. Expression of COX-2 and The Number of Neutrophil in Inflammation stage of Wound Healing Process after Systemic Administration of Ethanolic Extract Rosela. Inflammation is an initial stage of body’s natural response to tissue damage.The use empirically plants often used for traditional medicine because it is easily found in the community and fewer side effects. Flavanoid presence of roselle (Hibiscus sabdariffa) is thought to have anti inflammatory effects. This study aimed to know the effect of systemic administration of Roselle ethanolic extract toward COX-2 expression and neutrophils number in the inflammatory phase of wound healing processes. Roselle was obtained from plantations in Bulusari hamlet, Tarokan, Kediri, EastJava. Making roselle extract was performed in LPPT unit 1 UGM Yogyakarta by percolation ways. Wistar rats were given a total of 36 injuries with ɵ 3 mm punch biopsy of the buccal mucosa. Subjects were divided into three groups, each group of 12 rats. The division consists of the negative control group (saline), positive control (ibuprofen 20 mg/kg) and treatment (roselle extract 500 mg/kg). Giving drink suitable group once daily for four days. On day 1, the 2nd, 3rd and fourth rats were sacrificed, and mucosal tissue injury was made histological preparat. Hematoxylin eosin staining (HE) was performed to observe the number of neutrophils. COX-2 expression was found in preparations for immunohistochemical staining using rabbit polyclonal COX-2 antibody (Lab Vision, USA). The number of neutrophils and expression of COX-2 is calculated under a light microscope data were analyzed using Two-way ANOVA and LSD. The results showed that the expression of COX-2 and neutrophil number were least in the treatment group compared to the control. Clinical observation on day four also appears around the wound has completely closed the subject after administration of roselle drink. It was concluded that the ethanolic extract of roselle can inhibit COX-2 expression and decrease the number of neutrophils that can be used as an anti-inflammatory ingredient.

Effect of Herbal Toothpaste Application Method on Production of Volatile Sulfur Compound. Volatile sulfur compound (VSC) is a component of the gas produced by bacteria in the oral cavity, consisting of hydrogen sulfide,methyl mercaptan and dimethyl sulfide. This gas is often used as an indicator to assess the status of bad breath. Herbalbased dental paste has been reported in previous studies to inhibit the growth of germs that cause periodontal disease. Plaque Bacteria in the oral cavity can be reduced by tooth brushing and/or the use of antiseptic material. Two groups of subjects chosen were given treatment using herbal toothpaste in different ways: the first group was by brushing teeth with herbal toothpaste the way they usually do it and the second group was given the treatment by applying herbal paste in the left and right molar region of maxilla. The sampling was performed before treatment, 5 minutes and 2 hours after brushing teeth or applying herbal paste. The result of the experiment indicates that the use of herbal toothpaste with toothbrush and applying method has the same pattern on each component of the sulfur gas that is an increase after five minutes post-application and then a decrease after 2 hours post-application. Herbal toothpaste which is applied by means of brushing or by applying to the teeth affected the levels of VSC components; the level of Hydrogen sulfide decreased, the level of methyl mercaptan was relatively stable, and the level of dimethyl sulfide increased. Herbal toothpaste can be used in a common brushing way or by applying it to the teeth to reduce the levels of VSC gases, especially Hydrogen sulfide in normal subjects.

Deformasi slot braket dapat mengurangi besar gaya torque yang akan dihantarkan ke gigi dan jaringan pendukungnya. Beberapa braket stainless steel yang beredar dipasaran belum pernah diteliti kualitasnya dalam perawatan ortodonsi. Tujuan penelitian adalah untuk membandingkan besar gaya torque akibat sudut puntir 30° 45° kawat stainless steel dan deformasi slot permanen akibat gaya torque tersebut antara kelompok merk braket (3M, Biom, Versadent, Ormco dan Shinye). Penelitian dilakukan pada lima puluh braket stainless steel edgewise dari lima kelompok merk braket (n=10) di lem ke akrilik. Masing-masing braket dilakukan pengukuran tinggi slot dengan mikroskop stereoskopi lalu dipasang ke alat uji torque yang sudah dibuat untuk penelitian ini. Setelah dilakukan uji torque, braket di ukur kembali tinggi slotnya dan dibandingkan dengan pengukuran sebelumnya untuk mengetahui adanya deformasi slot. Hasil analisis statistik menunjukkan perbedaan bermakna besar gaya torque pada sudut puntir 30° dan 45° antara Biom dan Shinye dengan Omrco. Gaya torque paling besar yaitu pada merk braket 3M (30°= 442,12 gmcm dan 45°= 567,99 gmcm), sedangkan yang terkecil adalah Biom (30°= 285,50 gmcm, 45°=361,38 gmcm). Perbedaan deformasi slot braket terjadi hampir pada semua kelompok merk braket. Deformasi slot braket hanya terjadi pada merk braket Biom (2,82 µm) dan Shinye (2,52 µm). Kesimpulan, salah satu faktor yang mempengaruhi besar gaya torque dan terjadinya deformasi slot yaitu komposisi dan proses manufaktur dari braket stainless steel. Proses manufaktur yang tidak sesuai standar dapat menyebabkan kualitas braket yang buruk. Deformasi slot permanen dalam penelitian ini terjadi pada merek braket Biom dan Shinye.Slot Deformation of Various Stainless Steel Bracket Due to Torque Expression On The Wire. Bracket slot deformation can reduce the amount of torque that will be transmitted to teeth and supporting tissues. The quality of some stainless steel brackets in the market is still questionable for orthodontic treatments. This research aims to compare the amount of torque expression due to torsion angle of 30° and 45° at the stainless steel wire and bracket slot permanent deformation caused by the torque in each examined bracket brands (3M, Biom, Versadent, Ormco and Shinye). Fifty Stainless Steel Edgewise brackets from five different brands (n = 10) were attached onto an acrylic. Each bracket slot width was measured with a stereoscopic microscope and then mounted onto a torque apparatus that had been prepared for this study. Once the torque test was done, the width of bracket slot was re-measured to determine if there was a difference from initial bracket slot width at 45°. The results of ANOVA showed significant differences in the amount of torque at torsion angle of 30°and 45° between Biom and Shinye with Omrco. The 3M transmitted the highest load (30°= 442,12 gmcm and 45°= 567,99 gmcm), while the lowest was of Biom (300 = 285,50 gmcm and 450 = 361,38 gmcm). Differences in slot bracket deformation were found virtually in all groups of bracket brands. Deformation of bracket slots occurs only in Biom (2.82 µm) and Shinye (2.52 µm). From the observation, it is concluded that one of the major factors that affect torque and deformation of bracket slot is composition and manufacturing process of the stainless steel brackets. Manufacturing process that does not meet the standard can lead to a poor quality bracket. Permanent slot deformation in this study occurrs with Biom and Shinye bracket brands.

Gigi kaninus sangat penting untuk estetika dan fungsi mastikasi seseorang. Impaksi gigi adalah gagalnya gigi untuk muncul ke dalam lengkung gigi yang dapat disebabkan karena kekurangan ruang, adanya sesuatu yang menghalangi jalur erupsi gigi atau karena faktor keturunan. Prevalensi impaks gigi kaninus maksila adalah 0,9-2,2%, sedangkan impaksi gigi kaninus mandibula lebih jarang terjadi. Alternatif perawatan gigi impaksi kaninus maksila adalah operasi exposure dan diikuti dengan kekuatan ortodontik untuk membantu erupsi dengan alat cekat ortodontik. Tujuan dari perawatan adalah untuk koreksi malrelasi dan malposisi gigi geligi, khususnya koreksi gigi kaninus impaksi menggunakan teknik Begg. Pasien laki-laki, 19 tahun, gigi sangat berjejal, gigi kaninus kanan kiri rahang atas dan gigi kaninus kanan rahang bawah impaksi, kelas I, deep overbite, overjet 3 mm dan overbite 8,8 mm. Perawatan dilakukan dengan menggunakan alat cekat Begg dengan tanpa pencabutan. Operasi exposure dilakukan untuk membuka gigi kaninus kanan kiri atas yang impaksi yang diikuti perekatan braket ortodontik.

Radiograf panoramik mencitrakan gigi-geligi rahang bawah dan atas beserta seluruh jaringan pendukungnya dalam sebuah citra tunggal, proses pemeriksaannya murah, cepat, dan mudah, serta paparan radiasi yang diterima oleh pasien relatif rendah. Di samping memiliki sejumlah keunggulan tersebut, radiograf panoramik juga memiliki kelemahan karena gambaran yang dihasilkan pada teknik radiografi ini mengalami distorsi geometris, sehingga hasil pencitraan pada radiografi panoramik cenderung tidak sesuai dengan ukuran struktur anatomi yang sesungguhnya pada pasien. Penelitian ini bertujuan untuk mengetahui perbedaan hasil pengukuran horizontal pada preparat mandibula dibandingkan dengan pengukuran horizontal pada citra radiograf panoramik, serta untuk mengetahui seberapa besar distorsi pengukuranhorizontal pada radiograf panoramik. Sampel penelitian berupa 56 buah preparat mandibula yang masing-masing diberi 23 buah metal marker. Radiograf panoramik diambil dari masing-masing sampel. Pengukuran horizontal pada sampel menggunakan sliding caliper digital, sedangkan pengukuran horizontal pada radiograf panoramik menggunakankomputer. Hasil penelitian menunjukkan bahwa terdapat perbedaan rerata yang bermakna (p<0,05) antara hasil pengukuran pada radiograf panoramik dibandingkan dengan hasil pengukuran pada preparat mandibula, kecuali pada hasil pengukuran horizontal regio gigi geligi posterior dan regio median line hingga posterior korpus mandibula. Hasil penelitian ini menunjukkan bahwa pada penempatan posisi kepala pasien yang memenuhi standar akan dihasilkan radiograf panoramik dengan distorsi geometris berupa penyempitan dimensi horizontal pada regio anterior mandibula. Pengukuran horizontal pada radiograf panoramik memiliki akurasi yang baik jika dilakukan pada regio posterior, namun cenderung tidak akurat jika dilakukan secara memanjang melintasi median line. Differences of Horizontal Measurement on Dry Mandibles and Panoramic Radiographs. Panoramic radiograph produces one single image of both maxillary and mandibular dental arches and their supporting structures. This technique is cheap, fast and easy, with relatively low radiation exposure received by patients. However, the panoramic radiograph also has some disadvantages related to its geometric distortion. The images of patient’s anatomical structureson panoramic radiograph are not equal with their actual dimension. The aim of this study is to determine the distortion of panoramic radiograph, by comparing the horizontal measurements on panoramic radiographs with those on the real object, which was the dry mandibles. The samples of this study were 56 dry mandibles with 23 metal markers on each ofthem. Panoramic radiograph was taken from each sample. Horizontal measurements on dry mandibles were done using digital sliding caliper, while horizontal measurements on panoramic radiograph were done using computer. The result of this study shows that there were significant differences (p<0.05) between horizontal measurements on panoramicradiographs compared with the measurements on dry mandibles, except in posterior dental arch and median line up toposterior region of mandible corpus. The results of this study indicate that panoramic radiograph taken on standardized patient’s head positioning procedure would produce geometric distortion that tends to be narrow on mandibular anterior region. The horizontal measurements of panoramic radiographs show good accuracy in posterior region, but tend to be inaccurate if done extended across the midline.
