Filter by:This cross-sectional study aims to perform a population-based assessment of the incidence of decay, dental fillings, root canal fillings, endodontic lesions, implants, implant and dental abutment crowns, pontic crowns, and missing teeth, taking into account the location.
This randomized clinical study analysed the clinical use of a new bioceramic premixed CaSi-containing sealer in association with a warm carrier-based technique or a traditional epoxy resin based sealer. Methodology: Healthy patients requiring root canal treatments were enrolled. Periapical X-rays were taken preoperatively, after root canal filling and after 1, 6, and 12 and 24 months. Two evaluators assessed the Periapical Index (PAI) and the sealer extrusion. The healing rate and survival rate were also evaluated. Barnard test was used to assess the relationship of each potential prognostic factor with periapical index (PAI) at 12-month follow-up. The significance level was set at 0.05.
The object of the present study is to compare the effectiveness of conventional endodontic treatment with that of endodontic treatment combined with Photodynamic Therapy (PDT) in patients with apical lesion. Clinical and radiographic examination of the patients will be used to evaluate the presence of apical lesion, size of the lesion, and PAI index. Microbiological examination (evaluation of UFC/ml) will be carried out to assess the disinfection of the root canals. The success rate of the treatment will also be assessed. Endodontic treatment will be carried out in accordance with habitual standards and practices. PDT will be applied with diode laser (660 nm, 100 mW) and methylene blue will be used as photosensitizer (PS). Patients of the Endodontics Service of Universidad San Sebastián (Santiago campus) will be recruited for the study.
Dental periapical damages can have various reasons and is reflected by a radiolucent lesion on complementary imaging: angulated retro-alveolar (RA) radiographs, dental panoramic radiographs, and three-dimensional imaging such as computed tomography (CT) or cone-beam computed tomography (CBCT). For the radiographic detection of these deep periodontal lesions, the dental panoramic represents a first approach commonly performed with relatively low radiation. The investigation can be followed by retroalveolar radiology imaging that are more localized and more precise. However, using these techniques, the detection rates of these lesions are low (20% and 36% respectively), it is necessary to use three-dimensional tomographic investigation to be more discriminating (69%). The gold standard imaging for detection of these lesions is CBCT followed by retroalveolar radiography (~2x less sensitive than CBCT) and panoramic radiography (~2x less sensitive than RA). Although not a full-thickness radiograph, the dental panoramic has the advantage of being more commonly performed while being less radiating than CBCT and giving a global view of the dental arches on a single image. The detection of periapical lesions is done after a clinical assessment and a visual appreciation of the complementary examinations. The aim of this project is to improve the detection of periapical lesions, by developing an algorithm able to identify them on a panoramic dental radiograph. This algorithm is based on a deep learning system trained with reference data including panoramic dental imaging and CBCT with an acquisition interval of less than 3 months. The model is based on a previous work, will improve the quality of the initial data (using CBCT), using innovative artificial intelligence algorithms (transfer learning).
The aim of this study was to compare the Antibacterial Efficacy of Diode Laser 810nm and Photodynamic therapy in reducing bacterial microflora in endodontic retreatment of teeth with periradicular lesion.
