Abstract

Model study is one of the standard orthodontic components which is important for diagnosis and treatment plan, but in some patients with the high gag reflex, it will be difficult to get this kind of study models. The existence of a new device which is able to show the condition of patients mouth in three space areas (axial, sagittal, and coronal) is expected to be an alternative when a study model is difficult to get. The purpose of this study is to find out whether or not there are any differences on the size of canines mesiodistal, first and second premolar resulted from CBCT imaging with Moyers analysis on the study models. The method of the research is comparative descriptive. Measurements are made on 10 CBCT imaging results and 10 study models. The mesiodistal size, the result of CBCT imaging is measured by the available computer program and also the mesiodistal size of the study models is measured using a sliding compass, and then the size of canines, first and second premolar teeth resulted from CBCT imaging are compared to the result of Moyers method analysis on the study models. The t-test is used to find out if there is a difference between teeth size value between the CBCT imaging with the study models. The significance is determined based on the p-value < 0,05. The statistical test result shows a significant difference between the size of canines mesiodistal, first and second premolar teeth, the result of CBCT imaging and the Moyers analysis result in the study models in which t count > t table.

Abstract

Introduction: Clicking is the most common clinical symptom in patients with Temporomandibular Disorder (TMD). Lacking attention by either the patient or dentist, many patients were found to have suffered from morphologic alteration of the condyles seen in the panoramic radiograph inadvertently. The purpose of the study was to determine the differences of condyle morphology of the Temporomandibular Joint (TMJ) with and without the existence of clicking by means of digital panoramic radiographs. Methods: This study was based on an analytic descriptive research, whereas subjects are digital panoramic radiographs taken from clicking and non-clicking patients at the Radiology Installation of Dental Hospital Universitas Padjadjaran. 16 samples of each group were chosen in a non-random purposive sampling manner. Results: The research showed the mean of condyle morphology, HOC height  on clicking (6.31 mm) was shorter than the non clicking (7.63 mm), the width of HOC on clicking (10.38 mm) was higher than the non clicking (10.22 mm) and height of the processus condylaris on clicking (19.70 mm) was shorter than non clicking (20.04 mm). Ratio of the high of HOC, width of HOC and high of processus condylaris were 12.13 (clicking), and 12.63 (non-clicking). Conclusion: There was no significant difference between the morphology of the TMJ condyle between clicking and not clicking group, except on high of HOC.

Abstract

Introduction: Abnormalities of the dental pulp can have several different diagnoses. Therefore, the dental pulp characteristics must be known in more detail and clear so that diagnosis be established more precisely and accurately.  One characteristic of the pulp can be seen from the density value through the 3D Cone Beam Computed Tomography (3D CBCT). Methods: The study  was  conducted  with  a  simple  descriptive  method.  The population is all the data 3D CBCT of patients who visited the Universitas Padjadjaran Dental Hospital (RSGM Unpad) in 2012. Samples of the research were 75 pulps  with normal, inflammation, and necrosis conditions and calculate the average density value. Results: Density values for dental pulps in the normal teeth between 465 - 775 HU, the inflammation teeth between 243.5 - 396 HU, and necrosis teeth between - 461.5 - -170 HU. Conclusion: There are differences in dental pulp density between the normal pulp, inflammation and necrosis through 3D CBCT.

Abstract

Introduction: Radiographic examination is needed to determine the diagnosis of pulp necrosis in addition to a clinical examination. Visual observation was limited in seeing the colour change degree and hence an effort taken by assessing the histogram value. The purpose of this study was to obtain the pulp chamber histogram pattern which reveals its grey scale value, trend, intensity average, histogram variation, and histograms maximum regional of interest (ROI) through digital periapical radiograph. Methods: This study was a descriptive study of the total of nine pulp chamber periapical radiograph data samples. The samples were divided into three groups, the 1st group was the data taken prior to the tooth extraction, the 2nd group was the data collected after the teeth extraction, and the 3rd group was the data of priorly pulpless teeth. Results: There was a tendency of histogram graphic shifting to the left side, likely towards the radiolucent area on ROI of the pulp at the apical region, whilst histopathologically, a massive infiltration of a round PMN cells was found in the area. This finding supported the determination of pulp necrosis diagnose. Conclusion: The tooth with a pulp necrosis showed a tendency that led to radiolucency on periapical radiograph histogram, and histopathologic examination showed massive infiltration of a round PMN cells, thus supported the pulp necrosis diagnose.

Abstract

Pendahuluan: Kista dentigerous atau kista follikular adalah kista odontogenik jinak yang tumbuh lambat akibat kelainan perkembangan epitel email pembentuk gigi. Kebanyakan kista dentigerous berhubungan dengan gigi molar ketiga mandibula, tetapi jarang melibatkan impaksi gigi supernumerary anterior rahang atas, sehingga pada tulisan ini akan menganalisis kista dentigerous akibat impaksi gigi supernumerari anterior rahang menggunakan CBCT terhadap seorang laki-laki berusia 50 tahun. Laporan Kasus: Keluhan berupa pembengkakan pada cuping hidung dan gusi anterior rahang atas disertai keluarnya darah dan cairan menyerupai nanah. Hasil CBCT menunjukan gambaran lesi radiolusen berbatas radioopak meluas di daerah rahang atas hingga sinus maksilaris dextra dan sinistra berbentuk irreguler disertai gambaran radioopak pada bagian tengah lesi (menyerupai gigi supernumerary). Suspek radiologis adalah kista dentigerous karena impaksi gigi supernumerary anterior rahang atas disertai penebalan sinus maksilaris sinistra. CBCT menawarkan pendekatan alternatif yang menjanjikan karena menyediakan gambar sub-milimeter dengan resolusi kualitas diagnostik yang tinggi, waktu pemindaian singkat dan mengurangi dosis radiasi. Simpulan: Gambaran CBCT pada kista dentigerous gigi supernumerary anterior rahang atas dapat terlihat akurat, sehingga sangat berguna sebagai alat penunjang untuk diagnosis dan perencanaan operasi pada kasus kista dentigerous. Penampakan 3D CBCT menawarkan akurasi yang tinggi dalam merencanakan perawatan bedah, sehingga hasil perawatan lebih efektif. ABSTRACTIntroduction: Dentigerous cysts or follicular cysts are benign odontogenic cysts that grow slowly due to tooth-forming enamel epithelial developmental abnormalities. Most dentigerous cysts are associated with mandibular third molars, but rarely involve impaction of the maxillary anterior supernumerary teeth, so in this paper we will analyze dentigerous cysts due to impact of anterior jaw supernumerary teeth using CBCT on a 50-year-old man. Case Report: Complaints include swelling of the nostrils and anterior maxillary gums accompanied by blood and pus-like fluid. CBCT results show radiolucent lesions with well-defined radiopaque boundaries extending in the upper jaw region to the maxillary and left maxillary sinuses irregularly shaped with radiopaque features in the center of the lesion (resembling supernumerary teeth). Radiological suspicion is a dentigerous cyst caused by impaction of the maxillary anterior supernumerary teeth accompanied by thickening mucous of the left maxillary sinus. Conclusion: CBCT offers a promising alternative approach because it provides sub-millimeter images with high diagnostic quality resolution, short scanning times and reduced radiation doses. CBCT evaluation in this case shows the entire large area of the lesion and helps the surgeon to accurately assess the extent of the lesion and also determine the relationship of the lesion to the adjacent vital structures. Keywords: CBCT, dentigerous cyst, impaction, supernumerary teeth, anterior supernumerary teeth, anterior.

Abstract

Pendahuluan: Radiografi periapikal dapat digunakan untuk mendeteksi tulang alveolar pada perawatan gigi tiruan jembatan. Pembuatan gigi tiruan jembatan harus memenuhi syarat-syarat biologis. Apabila adaptasi marginal buruk, penempatan margin intracrevicular terlalu dalam, permukaan restorasi yang kasar dan restorasi yang overkontur dapat menyebabkan peradangan lokal seperti inflamasi gingiva, peningkatan kedalaman probing dan kehilangan tulang alveolar. Tujuan penelitian ini untuk mengetahui bagaimana deskripsi tulang alveolar pasca perawatan jembatan di RSGM UNPAD ditinjau dari radiografi periapikal. Metode: Jenis penelitian deskriptif dengan populasi adalah seluruh hasil radiograf periapikal pada pasien sebelum dan sesudah perawatan jembatan posterior yang datang ke RSGM Unpad dan sampel adalah radiograf sebelum dan sesudah perawatan jembatan posterior sebanyak 17 pasien setelah insersi 1 minggu dan 2 pasien setelah insersi 4 minggu. Pengukuran ketinggian tulang alveolar menggunakan Metode Proksimal RABL (Radiographic Alveolar Bone Loss) yang dihitung memakai jangka sorong. Hasil : Kehilangan tulang alveolar setelah insersi 1 minggu pada mesial dan distal yaitu 0,003 mm, setelah insersi 2 minggu 0,007 mm pada mesial dan 0,025 pada distal,setelah insersi 3 minggu 0,025 mm pada mesial dan 0,019 mm pada distal, setelah insersi 4 minggu 0,075 mm mesial dan 0,063 mm distal. Simpulan: Pasca perawatan jembatan, ditinjau dari radiografi periapikal, terdapat kehilangan tulang alveolar ringan berdasarkan metode proksimal RABL.Kata kunci : Gigi tiruan jembatan, radiograf periapikal, tulang alveolar. ABSTRACTIntroduction: Periapical radiography can be used to detect alveolar bone in bridge denture treatment. The making of bridge denture must fulfil biological requirements. Poor marginal adaptation will lead to deeper intracrevicular margin placement, rough surfaces, over contour restoration can cause local inflammation such as gingival inflammation, increased probing depth and alveolar bone loss. The purpose of this research was to know the description of alveolar bone after bridge denture treatment reviewed through periapical radiography. Methods: This research was descriptive with the population of all radiograph periapical treatment of posterior bridge in Universitas Padjadjaran Dental Hospital and the sample was radiograph periapical before and after bridge treatment of as much as 17 patients after 1-week insertion and 2 patients after 4-weeks insertion.  Alveolar bone height measurements was carried out using the RABL (Radiographic Alveolar Bone Loss) proximal method calculated using the Vernier callipers. Results: The results indicated that alveolar bone loss occurred after 1-week insertion on the mesial and distal was 0.003 mm; after 2-weeks insertion was 0.007 mm on the mesial and 0.025 mm on the distal; after 3-weeks insertion was 0.025 mm on the mesial and 0.019 mm on the distal; and after 4-weeks insertion was 0.075 mm on the mesial and 0.063 mm on the distal. Conclusion: Post bridge treatment, in terms of periapical radiography, found a mild alveolar bone loss based on the proximal RABL method.  Keywords: Bridge denture, periapical radiograph, alveolar bone.
