ABSTRACT Amelogenesis imperfecta (AI) is a genetically inherited disorder characterized by defective enamel formation, posing a significant challenge in esthetic treatment for clinicians. The choice of an appropriate treatment modality is largely dictated by the specific type of AI. This paper aims to elaborate on therapeutic options available for patients under 18 with amelogenesis imperfecta, emphasizing a multidisciplinary treatment approach.
ABSTRACT The aim of the study was to compare and evaluate fracture resistance of Custom Cast post and core, Pre-fabricated post and core and CAD/CAM fabricated post and core. Material and Methods: 60 transparent endoblocks with single root canal that simulated natural teeth were randomly divided into 3 groups of 20 endoblocks each. The working length of the root canal in the transparent endobloc was determined. The canals were prepared with K-file sizes 10,15 and 20 followed by Protaper Ni-Ti files (sizes S1, S2, F1 and F2); Dentsply by using the crown down technique to the full working length. Gutta percha was removed from the root canals with Peeso drills to a depth of 12 and post spaces were prepared in all groups with the special preparation drills of each system leaving 5mm of gutta percha in all specimens. For group 1, after root canal treatment of 20 samples, Prefabricated plastic burnout posts were coated with pattern resin and then inserted into the canal with slight pressure to take the canal impression which was further send for casting followed by using GC gold label glass ionomer resin for luting. For group 2, the Prefabricated EDELWEISS post and core were placed into the canal and the cement was allowed to set. For group 3 impression of the canal was made using pattern resin. The burnout post was scanned with a lab scanner and designing was done using the designing software. CAD-CAM fabricated post and core was placed into the canal and luted with the help of glass ionomer cement. Composite core fabrication was done and the specimens were secured in a universal load-testing machine at an angle of 1300 to the long axis of the tooth. Until fracture occurred, a compressive force was applied at a crosshead speed of 1 mm/min. The fracture loads were determined. Mean failure load for each group was recorded in N. Results: The mean fracture load of Group 1, was found to the maximum followed by Group 3 & Group 2 samples, in decreasing order. Conclusion: The mean ......
ABSTRACT The arrival of digital workflow has caused an important evolution in the way dentistry is performed nowadays. Imaging through intraoral scanning systems (IOS) and cone beam computed tomography (CBCT) combined with computer aided design and manufacturing systems (CAD/CAM), make it possible to simplify procedures in all areas of dentistry. Digital techniques are tools that allow more assertive diagnoses, as well as the planning and development of treatments with greater safety, effectiveness and speed. The purpose of this review is to learn about the application of the digital tools that give rise to the development of digital workflow and its general applications in dentistry, in the search for areas of opportunity where this technology can be useful for the development of new techniques that allow that allow for personalized patient-centered care.
ABSTRACT Introduction: Maxillomandibular tumors are neoformations that develop on the mandible or maxilla, and may be benign or malignant. When they are related to elements of the dental system, they are called odontogenic maxillo-mandibular tumors. Objective: To study the anatomical and clinical features of odontogenic maxillo-mandibular tumors. Patients and Methods: This was a retrospective, observational, descriptive, analytical and monocentric study conducted in the Department of Stomatology and Maxillofacial Surgery over a 6-year period, from March 2016 to June 2022. All patients with histologically proven odontogenic maxillo-mandibular tumours were included. Non-odontogenic tumours and incomplete files were excluded. The parameters studied were: Epidemiological data (prevalence, sex, age, occupation, history), histo-clinical data (time to consultation, functional signs, physical signs), paraclinical data (imaging, anatomopathology). Results: The number of cases collected was 35. Odontogenic maxillo-mandibular tumours accounted for 34.3% of all maxillo-mandibular tumours. The mean age was 31.63 years, with extremes ranging from 03 to 68 years. The sex ratio was 0.94, with females predominating. Unemployment accounted for 40% of cases. Maxillary or mandibular swelling was present in 94.3% of patients, and dental extraction was performed in 34.3%. CT scans were performed in 82.8% of patients. Anatomopathological examination revealed 88.6% benign tumours and 11.4% malignant tumours (4 patients). Ameloblastoma accounted for 61.3% of benign tumours. Ameloblastic carcinoma accounted for 50% of malignant tumours. Conclusion: Maxillo-mandibular odontogenic tumours are common and are revealed by maxillary or mandibular swelling. Their characteristics differ according to whether they are benign or malignant. Ameloblastoma is the most common maxillo-mandibular odontogenic tumor.
ABSTRACT Digital workflow in dentistry is an innovation technique that has made great progress in recent years that provides personalized patient care incorporating CAD/CAM technology (Computed Assisted Design/Computed Assisted Manufacturing) for the visualization and digital manipulation of structures obtained from CBCT (Cone Beam Computed Tomography) or intraoral scanner. This allows to build structures that can help the dentist in treating patients in a personalized way. The digital flow process mainly consists of three pillars: image acquisition, visualization and manipulation of three-dimensional models and 3D printing. This clinical methodology can be used in all fields of dentistry, where the design of anatomical posts to replace the use of conventional fiberglass poles stands out. The above allows to a predictable dynamic of treatment which influences the decrease of risk of fracture due to overload of chewing forces. The digital flow is improved with the integration of bioengineering, the technological and biological knowledge of this discipline allows increasing the effectiveness and efficiency of the process to obtain better results.
ABSTRACT Introduction: Odontogenic maxillofacial cellulitis are infections of the cellulo -adipose tissues of the face of dental origin and which can be life-threatening for the patient. This study aims to determine the epidemiological and clinical profile of odontogenic maxillofacial cellulitis in children. Patients and Method: This is a retrospective, cross-sectional, observational, single-center study involving patients aged 0 to 18 years hospitalized at the CMF Stomatology department in Owendo from 2016 to 2022. Incomplete files, patients treated on an outpatient basis and those with non- odontogenic cellulitis. The epidemiological and clinical parameters studied were age, sex, residence, level of education, lifestyle, contributing factors, reason for consultation, consultation time, type of cellulitis, topography of the causal tooth, and sign of gravity. Results: 72 patients collected. The mean age was 9.03±5.71 years. The male gender represented 58% with a sex ratio of 1.4. 9.7% of patients brushed their teeth twice a day, 47.2% of patients did so once and 44.1% of patients did not brush their teeth. 54.2% of patients performed soft brushing, 2.8% of patients performed hard brushing. 79.2% of patients consumed cariogenic foods. 62.3% of patients self-medicated with NSAIDs. 56% of patients consulted between 1-10 days. 94% of patients presented with circumscribed cellulitis and 6% of patients presented with diffuse cellulitis. 5.6% of patients had dysphagia and 5.6% of patients had tight trismus. Conclusion: Maxioll-facial cellulite odontogenic infections are predominant in boys. They are favored by taking NSAIDs and cariogenic foods. The circumscribed stage is frequently encountered.
ABSTRACT The word "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation. These words define the unique qualities of lasers, whose application in the dental field focuses on dental therapy, aesthetic dentistry, prosthetics, and oral and periodontal surgery. Through this literature review, the application of lasers in dental clinical practice and its relevant parameters will be evaluated from a bioengineering perspective. Bioengineering can serve as a transdisciplinary bridge between engineering and dentistry, which is refined in the use of lasers to enhance the oral health of patients.
