Abstract Background: Amelogenesis Imperfecta (AI) is a disorder of tooth development characterized by abnormal enamel formation. In order to detect other dental and jawbone abnormalities that could be associated with AI, a retrospective and analytic study was conducted comparing panoramic radiographs of AI and non-AI patients. Material andMethods: Digital panoramic radiographs of 60 AI and 60 non-AI patients were examined. Abnormalities in dental number, size, shape, eruption, and in the shape of the dental arches were checked and blindly recorded by two experimented observers. Descriptive statistics using percentages and chi-square test with .05 level of significance value was used. Results: Prevalence of supernumerary teeth, dental agenesis, microdontia, taurodontism, radicular dilacerations, dental inclusions, temporary teeth persistence, and pulp calcifications was significantly higher in AI patients compared to control patients. Prevalence of periapical images, cysts
VisiterThe aim of this study is to present a global management of bruxism in order to satisfy the requirements of the patient and to minimize the risk of prosthetic failure. The success of prosthetic rehabilitation integrated within the manducatory system depends on several parameters that must be taken into consideration. A 70-year-old patient, in good general health, was consulting the removable partial denture department at the dental clinic of Monastir (Tunisia) for an aesthetic and functional reason. The patient reports a diurnal and especially nocturnal grinding of the teeth which leads to a suspicion of bruxism. The patient seems to be stressed and nervous due to his work which is driving instructor. Prosthetic management with combined prosthesis was done. Yet, the clinician has to take into consideration the maintenance sessions, the perfect occlusal adjustment and the patient's compliance after prosthesis insertion and wearing a protective splint. Regular follow-up is important to de
VisiterAbstract Non-carious cervical lesions have always posed difficulties in terms of etiological diagnosis, prevention and restoration. Interception of the causative factors is sometimes not enough to meet patients' needs, and curative treatment is required. Restoration of the loss of substance with an adhesive biomaterial is essential, to reduce thermal sensitivity and improve aesthetics. Such restoration is a complex exercise for the clinician, due to the difficulties that may be encountered. These difficulties are indeed linked to the particular location of these lesions, making their isolation, visibility and access complex. The aim of this paper is to describe the management of non-carious cervical lesions, detailing both the therapeutic and preventive approaches. Keywords: Cervical lesion, Sclerotic dentin, Adhesion, Composite resin.
VisiterAbstract The appearance of CAD/CAM has led to a disruption of conventional laboratory manufacturing techniques. Some design steps are added, modified or removed. In both cases, whether digital or conventional technique, the goal is to achieve the same result: a stable prosthesis, adjusted and integrated into the patient’s dental and mucous structures. Selective Laser Melting (SLM) is an additive manufacturing technique producing metal pieces (crowns, bridges, metal frames) using a high-power laser. This manufacture is direct, so, instead of making models in wax or calcinable resin, we directly manufacture metal fittings, mainly cobalt-chrome. Through this article we will describe the SLM technique for removable partial denture metal framework, the advantages and disadvantages of this technique compared to the conventional procedure. Keywords: Laser Melting, Denture Fabrication
VisiterDear Editor, It is with great interest that we have read the original article entitled «Deep dental phenotyping and a novel FAM20A variant in patients with amelogenesis imperfecta type IG», published in your esteemed journal (Sriwattanapong et al., 2023). The publication was of high value considering that (i) it identifies a novel variant of FAM20A gene in amelogenesis imperfecta (AI) type IG patients, (ii) it describes physical/mechanical and chemical properties of AI teeth and (iii) it analyzes the expression of RNA and proteins in the corresponding AI gingival fibroblasts. Therefore, four variants of this rare disease were identified by the authors from the peripheral blood leukocytes of three AI patients using exome and Sanger sequencing. One of these variants was novel, contributing considerably to the understanding of the genetic basis of the disease. However, ultrastructural, and physical/mechanical properties were explored only on one permanent unerupted, and one primary er
VisiterAbstract: The prosthetic treatment of a maxillary edentulism bordered by an incisor is a source of therapeutic difficulties due to its particular topography generating biomechanical and aesthetic problems. We here report, the keys to the success of prosthetic rehabilitation using complexe combine prosthesis to meet the aesthetic and functional requirements of a patient with this particular edentulism. The clinical case has been presented according to a didactic approach to highlight the therapeutic difficulties and the different prosthetic treatment sequences to be respected to guarantee the integration of the prosthesis and its longevity. Key words: Partial edentulism, Denture Precision Attachment, incisor, aesthetic problem, biomechanical problem.
