Introduction-Les traumatismes bucco-dentaires sont des accidents fréquemment rencontrés ai cours de l’intubation orotrachéale pratiquée en urgence ou au cours de l’anesthésie générale. le but de ce travail était d’évaluer les pratiques des personnels de santé lorsqu’un traumatisme buccodentaire s’est produit au cours de l’intubation orotrachéale. Méthodes- Il s’agissait d’une étude transversale qui s’est déroulée dans les hôpitaux tunisiens durant la période s’étalant du mois de septembre au mois de novembre 2022. Un questionnaire auto-administré pré-testé était distribué auprès des personnels de santé pratiquant l’intubation orotrachéale dans un contexte d’urgence ou d’anesthésie générale. Les données collectées ont été saisies et traitées avec le logiciel SPSS version 18. Résultats- Soixante-sept personnes ont répondu au questionnaire. D’après les résultats de l’étude, au cours de leurs pratiques quotidiennes, 88 % des enquêtés ont déclaré avoir assisté à un traumatisme bu
VisiterThe aim of this study was to define the relation between load distribution and the number of implants supporting mandibular implant-supported screw-retained complete prostheses (ISCP). It is a three-dimensional (3-D) finite element study. Three models were simulated. The first one represents a 4-implant supported prosthesis (4ISP), the second one is a 3-implant supported prosthesis (3ISP) and the third one is a 6-implant supported prosthesis (6ISP). The 6ISP model showed the best bone stress distribution among all models. Its maximum stress value was 63.3 MPa. The 4ISP (98.9 MPa) showed a better bone stress distribution than the 3ISP (122.9 MPa). A flexion of the prosthesis was more important for the 4ISP than 3ISP and then 6ISP model at 10 MPa. In the 4 ISP and the 3ISP models, the anterior implants were more solicited. However, the stress was evenly distributed on the 6 implants, in the 6ISP model. Concerning, the stress distribution in bone, the uppermost stress was found
VisiterABSTRACT Objective: To identify the tobacco effect on flexural properties and the microhardness of three acrylic resins. Material and Methods: Three resins were tested: two thermo-polymerizable acrylic resins (RMB 20 and BMS 014) and one autopolymerized acrylic resin. The 3-point bending and microhardness tests were carried out with a universal tensile-compression machine and a micro-Vickers hardness tester. The acrylic resin specimens have been exposed for 21 days to cigarette smoke in a smoking room. Their mechanical strength was compared to unexposed samples. Statistical analysis was performed using the data processing software SPSS Statistics 21.0. Results: The flexural properties of the resins were affected by cigarette smoke only in the case of Major Base 20® (drop in strength with p= 0.02; 0.6; 0.7 and in elastic modulus with p= 0.86; 0.74 and 0.85 for Major Base 20®, BMS 014® and Major Repair®). The cigarette smoke affected significantly microhardness for all groups (
VisiterInflammatory granuloma caused by a vegetable foreign body is a lesion that can develop in the oral cavity. It results from the implantation of vegetable matter, leading to an inflammatory reaction and the development of bone resorption. This case highlights the importance of clinicians' awareness regarding this uncommon disorder.
VisiterConventional mandibular complete denture for patient with severe ridge resorption is challenging. The dental implant therapy may be a fascinating option for improving retention and stability however the neutral zone approach is an important alternative when implant therapy is impossible. Hence, residual ridge resorption becomes a challenging scenario for a clinician during fabrication of complete dentures. The neutral zone concept plays a significant role in overcoming these challenges. The neutral zone philosophy is based on the concept that for each individual patient there exists within the denture space a specific area where the function of the musculature will not unseat the denture and at the same time, where the forces generated by the tongue are neutralized by the forces generated by the lips and cheeks. Furthermore, denture stability is as much or more influenced by tooth position and flange contour as by any other factors. The modified neutral zone technique enhanced
VisiterAbstract Purpose The aim of this review was to compare the currently available root canal filling materials for primary teeth to zinc oxide eugenol (ZOE) to find a suitable alternative. The search question was: which root canal filling materials used in pulpectomy for primary teeth give better clinical and radiographic success rates than ZOE? Methods A systematic search was conducted using five databases, namely Cochrane central register of controlled trials (CENTRAL), MEDLINE via PubMed, Science Direct, Scopus and EBSCOhost using a selection of “MeSH terms”. The “Modified Jadad Scale” was used for the methodology assessment of the included studies. Results Out of 480 articles identified in the initial search, 8 articles met all the inclusion criteria. The results showed that, compared to ZOE, ZOE with calcium hydroxide and iodoform had better clinical and radiographic success rates, a resorption rate similar to that of the roots, faster resorption of extruded particles and a
