“…This procedure made simulated initial lesions look like those observed in vivo, thereby enabling simulation of incipient lesions, which are more difficult to detect. 11,12,13,19 The anatomical proximity between the root apex and the cortical air space is more relevant than the size of a periapical lesion in establishing OAC. 3,8 Therefore, the longer acid etching time was not a Table 3.…”

“…This was done by applying 70% perchloric acid (Merck Chemicals, Darmstadt, Germany) in the mesiobuccal and distobuccal root alveoli (Figure 1), thus generating the sites (n = 64) to be analyzed on CT images. 12,13 Some sites (n = 32) were exposed to acid for a shorter time, to generate incipient lesions (Time 1: 3 hours), whereas others (n = 32) were exposed for a longer time, to simulate larger lesions (Time 2: 4 hours).…”

The purpose of the present study was to test the applicability of cone beam computed tomography (CBCT) to evaluate the integrity of the cortical sinus close to periapical lesions. Two observers analyzed samples of 64 alveoli of first molar roots in macerated swine maxillas prepared with perchloric acid to simulate periapical lesions. The specimens were evaluated using CBCT (55-mm high and 100-mm diameter cylinder at 0.2-mm voxel resolution) for the presence of oroantral communication (OAC) caused by the simulated lesions. Sensitivity, specificity, and accuracy were calculated. Fair values were obtained for accuracy (66%-78%) and good values for specificity (70%-98%), whereas the values for sensibility showed relevant variation (41%-78%). For this reason, the interobserver agreement score was weak. CBCT proved capable of evaluating the integrity of the cortical sinus (absence of oroantral communication) when it lies close to an apical periodontitis lesion. However, the low interobserver agreement reflects the difficulty in performing diagnoses when OAC is adjacent to a periapical lesion, using the acquisition protocol adopted in this research. This could be attributed to the high level of image noise.

“…According to several studies, the probability of apical periodontitis existing and not being identified by periapical or panoramic radiography, is considerable [2][3][4] . On the other hand, cone beam computed tomography (CBCT) images are high resolution 1,3,5 , permitting a more precise identification of the apical periodontitis (AP), providing more effective information about the size and location, since the superimposition of the neighboring anatomical structures [1][2][3][4][6][7][8][9][10][11][12][13][14][15] is eliminated.…”

ObjectiveTo perform a descriptive study in order to evaluate apical periodontitis in endodontically treated teeth using cone beam computed tomography. Methods Eighty RESUMO ObjetivoRealizar um estudo descritivo para avaliar periodontites periapicais em dentes com tratamento endodôntico em tomografia computadorizada de feixe cônico. MétodosOitenta e seis exames que apresentaram pelo menos uma periodontite periapical foram selecionados e separados em dois grupos: 1 para a mandíbula, e 2 para a maxila. Todos os exames foram realizados na tomografia computadorizada de feixe cônico com os mesmos protocolos de aquisição, e o mesmo software de avaliação e de mensuração. As lesões foram classificadas de acordo com o índice periapical, mas sem considerar a expansão do osso cortical e/ou destruição. ResultadosCento e vinte sete dentes inferiores e 180 dentes superiores apresentaram periodontites periapicais com tamanho médio de 0,49 mm na mandíbula e de 0,75 mm na maxila. Observou-se que os pré-molares inferiores foram os dentes mais acometidos. Lesões identificadas entre os escores 0 e 1 corresponderam a 83,47% das lesões na mandíbula e 78,89% na maxila, sendo que 55,12% dos dentes tratados endodonticamente inferiores e 50% superiores não apresentaram lesões reincidentes ou em fase de reparação. ConclusãoHouve um predomínio de periodontites periapicais pequenas, sendo os pré-molares os dentes mais acometidos por estas lesões.Termos de indexação: Periodontite periapical. Tomografia computadorizada de feixe cônico. Diagnóstico por imagem. Tecido periapical.

“…Presently, the first line of disease diagnosis via imaging modalities relies mostly on x-ray images even though other modalities such as Magnetic resonance (MRI) and computer tomography (CT) provide more accurate interpretations [1]. This is also true for the field of dentistry where x-ray images are consistently used to assist dentists in deciding the appropriate treatment for patients [2].…”

“…The pathologies such as periapical radiolucency, widen periodontal ligament space and loss of lamina dura are the common abnormalities that related to the disease [1] [1]. Sometime these diseases can obviously be detected in an x-ray but on other occasion they can be missed since x-ray images are often very noisy and low in contrast [5]- [6].…”

Abstract-This paper presents qualitative and quantitative comparison between original images and four image enhancement techniques namely adaptive histogram equalization (AHE), contrast adaptive histogram equalization (CLAHE), median adaptive histogram equalization (MAHE) and sharp contrast adaptive histogram equalization (SCLAHE) applied to dental x-ray images. Dental x-ray images usually taken with low radiation dosage are often presented as dark, low in contrast and noisy. These problems are usually solved with image enhancement techniques. However, choosing an appropriate technique is not an easy task especially for the purpose of disease diagnosis of periapical related lesion. This research involves the collection of ten intra-oral dental x-ray images which were collected from the Faculty of Dentistry UiTM Shah Alam, Malaysia. Each of the enhancement methods is applied to every collected image. A dentist was then asked to do the evaluation using questionnaire. She graded the quality of the images and the diagnostic ability of the periapical pathology observed in the images. Subsequently the quantitative analysis using contrast improvement index (CII), signal to noise ratio (SNR) and root mean square error (RMSE) were done to investigate the characteristic of the images base on the dentist evaluation. The finding shows that the enhancement techniques managed to enhance the pathology slightly better than the original image.Index Terms-Contrast enhancement, adaptive histogram equalization (AHE), dental X-ray.
