“…Light leaked in darkrooms can also cause the film to be foggy because the silver halide crystals are more exposed than normal, so after the processing of the film the results darken, reducing the diagnostic value of the radiographs. 14…”

Objective: Marginal microleakage detection is performed to prevent secondary caries. The present study aimed to determine the difference in the accuracy between conventional and digital radiography methods in detecting marginal microleakage and the radiopacity measurement of restoration material. Methods: We used 44 anterior maxillary teeth after extraction that had been filled with class III glass ionomer cement and then planted in paraffin wax blocks. These samples were then systematically exposed using conventional and digital indirect periapical radiography techniques. Microleakage detection was measured using three marginal microleakage scales. The level of radiopacity of restoration material was measured using ImageJ software and calculated using the standard radiopacity value calculation formula. All data were analyzed using the Mann-Whitney U test. Results: Outcome data demonstrated that there was no difference (p = 0.6) between the two radiography techniques in detecting microleakage of restoration. However, radiopacity measurements revealed a significant difference (p = 0.0) between these two radiography techniques in their ability to determine radiopacity. Conclusion: The results suggest that there is no difference between conventional and digital indirect periapical radiography techniques in detecting microleakage of restoration material; however, a high radiopacity level was found from the digital indirect radiography technique.

“…DBI pertama kali diperkenalkan oleh McDonnel et al pada tahun 1993 dan seringkali disinonimkan dengan enostosis/endostosis, osteosklerosis, osteosklerosis periapikal idiopatik, bone scar, bone whorl, bone sclerosis, focal periapical osteopetrosis, dan bone eburnation. [5][6][7][8][9] DBI didefinisikan sebagai perubahan atau pembesaran tulang trabekular non ekspansif dan termasuk ke dalam lesi hiperplasia tulang, walaupun pada beberapa literatur menjadikan lesi ini segolongan dengan tumor jinak.…”

“…Jika dilakukan pemeriksaan histopatologis lesi ini akan menunjukkan jaringan padat terkalsifikasi tanpa ruang sumsum. 6,8,9,16 Secara radiografis, lesi ini biasanya berbentuk membulat, sedikit lebih lonjong, atau bahkan tidak beraturan dengan ukuran yang bervariasi pula antara 2 mm sampai 1-2 cm. Lesi ini well-defined terhadap tulang di sekitarnya walaupun pada sedikit kasus tampak menyatu dengan trabekula tulang sekitarnya.…”

“…Torus dan eksostosis juga secara radiografis mirip tetapi secara klinis lebih dapat dipalpasi, lesi DBI juga dianggap sebagai bentuk eksostosis internal. 8,9,17 Untuk dapat menegakkan radiodiagnosis dari suatu lesi radiopak asimptomatik DBI terdapat beberapa ciri-ciri yang perlu diperhatikan berdasarkan rekomendasi MacDonald dan Janksowski yaitu asimptomatik; bukan lesi mixed radiolusen-radiopak dengan penampilan lesi fibroosseous atau odontoma; tidak terkait langsung dengan karies atau restorasi besar; bukan penebalan lamina dura; tidak dikelilingi oleh lingkaran haloradiolusen; tidak terkait dengan resorpsi gigi yang berdekatan; tidak ada bukti perpindahan kanal alveolar inferior, lantai sinus maksilaris atau gigi yang berdekatan dengan lesi; menunjukkan lesi yang tidak ekspansif; juga ketika sisa-sisa gigi sulung atau permanen telah diidentifikasi secara jelas dan dikeluarkan dari diagnosis serta tidak khas dari kondisi lainnya. 3 Adapun karena lesi ini asimptomatik maka secara umum tidak memerlukan perawatan apapun.…”

Objectives: Dense Bone Island (DBI) is one of the lesions that are usually visualized on a panoramic radiographs in the form of total radiopaque in the periapical area of the mandibular premolar or molar but most of them are not directly related to the dentition. This case report is aimed to give summaries about the description of 3 DBI cases. Case Report: Three panoramic radiographs of patients with asymptomatic well-defined radiopaque lesions which was found incidentally in the periapical area of the left mandibular first premolar with two of them showing the lesions located exactly in the 1/3 apical of the root and one of them seen as root resorption like. From clinical information, all three cases reported no clinical symptoms and affected teeth are still vital. Conclusion: Incidental findings of well-defined radiopaque lesion in the periapical area of the premolar and molar of mandible that mostly do not damage the surrounding teeth lead to the diagnosis of dense bone island.

“…10 In addition, certain patient-related factors (trismus, gagging reflex, low cost) make panoramic radiography advantageous. 11 Panoramic radiography is a simple method for obtaining images by the synchronous rotation of the x-ray source and image receptor around the stationary patient but there is a magnifying factor associated with the image formation because of the distances between the radiation source, patient and image receptor. Additionally, projection geometry causes image distortion and superimpositions in the premolar region.…”

OBJECTIVE: The aim of this study was to compare the accuracy of five different radiographic methods for the detection of approximal caries on posterior teeth. MATERIALS AND METHOD: Seventy-two extracted posterior teeth with and without caries were studied. Intraoral bitewing radiographs were taken with film and a storage phosphor-plate system. Extraoral panoramic images were obtained by using the bitewing, orthogonal and standard programs of a digital panoramic radiography device. Images were evaluated by two observers. Intra-and interobserver weighted-kappa coefficients were calculated. Scores obtained from the five techniques were compared against the histological gold standard using receiver operating characteristics (ROC) curve analysis. Az values for each image type were compared using z-test and the level of statistical significance was set at 0.05. Sensitivity, specificity and false-positive rates were calculated for each method. RESULTS: Intra-and inter-observer agreement κ values were between 0.59-0.88 and 0.54-0.87, respectively. The Az value was greatest with conventional bitewing (0.760) and phosphor plate bitewing (0.756) and lowest with standard panoramic image program (0.639). The standard panoramic image program was significantly inferior to the other diagnostic methods (p<0.05). Sensitivity and specificity values were 0.64 and 0.85 for conventional bitewing, 0.64 and 0.87 for phosphor plate bitewing, 0.40 and 0.87 for standard program, 0.56 and 0.85 for orthogonal program, and 0.59 and 0.90 for extraoral bitewing program, respectively. CONCLUSION: In this study, conventional and phosphor plate bitewing images were found to confer similar diagnostic accuracy. Orthogonal and extraoral bitewing programs on panoramic devices were effective for reducing superimpositions. The diagnostic sensitivity of the studied methods for approximal caries was found to be low at the level of enamel.
