Filter by:This study aimed to evaluate the effect of growth hormone and non-surgical debulking of periapical tissues on healing of periapical pathosis
The goal of this clinical trial is to compare the effects of different intracanal medication between endodontic retreatment visits in previously failed root canal treatment patients (single root canal anteriors or premolars teeth). The main question it aims to answer are: - Is natural and synthetic intracanal Medicament effective in reducing or complete healing of Periapical lesions or not? the researchers will compare the effect of different intracanal dressing including: - nanocurcumin gel - curcumin gel - ciprofloxacin +ibuprofen gel - calcium hydroxide Paste as control group in between the endodontic retreatment visits to see if these medicaments work well on periapical lesion healing this outcome measured by Cone beam CT at base and after 1 year follow up period
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.
Introduction: To evaluate the survival and success rate of premolars with a previous root canal treatment which underwent to non-surgical retreatment or to extraction and implant replacement. Materials and methods: Patients visiting in the Clinical Endodontic Section of the School of Dentistry (University of Bologna) were eligible for the study. Out of these patients, those with previously root canal treated premolars fulfilled the inclusion criteria. Teeth were considered retreatable and restorable (Endo group) or not retreatable and not restorable (Implant group) on the basis of clinical and radiographical examination. Each patient was included in an annual recall programme and final evaluation was performed after 8 years. Clinical parameters were recorded. Differences in baseline characteristics between the two treatment groups were assessed using logistic regression analysis with clustered standard errors. Results were expressed for each variable as odds ratios (ORs) of implant rehabilitation to root canal retreatment with 95% confidence intervals (CIs). Survival and treatment success for the two study groups were estimated using the Kaplan-Meier method. The association of treatment group with time to event was assessed using Cox proportional hazard regression analysis with clustered standard errors to allow for intragroup correlation within teeth belonging to the same patient. Results were expressed as hazard ratios (HRs) of experiencing the study event among implants as compared to root canal retreatments with 95% CIs.
The goal of this observational study is to define the role of apical shaping and irrigation activation on root canal cleanliness. The main questions it aims to answer are: - does the effectiveness of irrigation activation depends on apical shaping? - can a similar success be achieved by increasing apical shaping without irrigation activation Participants will [describe the main tasks participants will be asked to do, treatments they'll be given and use bullets if it is more than 2 items].
The goal of this triple blinded randomized clinical trial is to evaluate the effect of combining different bioactive root end filling materials with composite bone graft (xenogeneic mixed with autogenous bone fragments) on the healing process of periapical tissues after endodontic micro-surgery procedure on patients with small to moderate sized lesions. The main questions it aims to answer are: Will the use of Totalfill in Endodontic surgeries show comparable results to the gold standard MTA? Will the addition of composite bone graft (Xenogenic and Autogenous) affect the healing of small to moderate sized lesions? Is there any interaction between composite bone graft and different bioactive root-end filling materials? Participants were allocated to 4 different groups according to the root-end filling material used with or without bone graft. Reseachers compared between MTA only group, Totalfill only group, MTA with bone group, and Totalfill with bone group to evaluate healing of the periapical lesion using CBCT after 12 months follow up period.
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 the study was to evaluate the effect of Piezosurgery and Trephine bur as cutting tools on post-operative sequelae including pain and swelling following guided endodontic microsurgeries.
