Objective: This study aimed to explore the prevalence, signs, and symptoms of different types of TMD (Temporomandibular joint disorders) disorders in Tunisian patients. Methods: A retrospective cross-sectional study was conducted using the clinical records of patients from the Department of Functional Exploration, Pain, and Orofacial Dysfunction of the Dental Clinic of Monastir. Results: TMD is associated with a female predominance, with a peak prevalence among those aged between 20 and 40 years. Pain and a limited range of motion were significantly more prevalent in women (p = 0.019 and p = 0.012, respectively). Clicking sounds were the most frequent joint noises (38.2 %). Crepitus was more prevalent among older adults (33 %). Of the different types of TMD, disk displacement with reduction was the most prevalent (n = 216, 39 %). Sleep bruxism was more prevalent than awake bruxism (20.7 % VS 9.5 %). Due to the heterogeneous TMD signs and symptoms, patients tend to seek medical
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
VisiterIntroduction: Utiliser l’arc facial ou la table de montage est une question toujours posée par les cliniciens à chaque fois que l’enregistrement de l’occlusion est nécessaire. Quels dispositifs choisir ? Et dans quelles situations cliniques ? Tels étaient les objectifs de cette étude. Méthodes : Il s’est agi d’une revue systématique de la littérature. La recherche bibliographique a été effectuée sur la base de données Medline et complétée par une recherche manuelle via Google Scholar pour identifier d’avantage d’articles rapportant le sujet de la revue. Les articles de type essai clinique randomisé publiés en français ou anglais sont les principaux critères de sélection. Résultats : Quatorze études ont été retenues. Dans onze articles, le traitement envisagé était la prothèse complète conventionnelle. Parmi eux, huit articles trouvent des meilleurs résultats cliniques dans la méthode avec la table de montage que celle avec l’arc facial. Trois articles n’ont pas prouvé de diffé
VisiterContext: Despite its undeniable advantages, the rubber dam (RD) is still struggling to claim its rightful place as the most effective used isolation tool in endodontics. The study aimed to estimate the prevalence of RD use during endodontic treatment and to identify factors associated with its use by Tunisian dentists. Materials and Methods: A cross-sectional study was conducted. An online Google Form was emailed to a sample of Tunisian dentists, randomly selected from the National Dental Council register. It contains 33 questions divided into five parts: demographic characteristics, general endodontic practice, clinical applications of RD, reasons for not using RD, and alternative methods. The sample size, comprising 300 dentists, was calculated considering a previous prevalence. Chi-square/Fisher exact tests and t test have been used to investigate factors influencing RD use. For the multivariable analysis, we used binary logistic regression. Results: Among the 174 respon
VisiterObjectives The aim of this study was to evaluate remaining filling materials of a bioceramic sealer (TotalFill BC sealer) and an epoxy resin sealer (AH Plus) after retreatment using a supplementary instrumentation (XP-endo Finisher). Materials and Methods Forty single-rooted teeth were selected for the study. The teeth were instrumented using ProTaper system and randomly divided into two groups (n¼20). Then they were obturated with either TotalFill BC/gutta-percha or AH Plus/gutta-percha using lateral compaction technique. Canals were retreated using ProTaper retreatment files and a solvent. The groups were subdivided (n¼10) according to the application or not of the XP-endo Finisher as a final step of retreatment. All roots were cleaved longitudinally and examined under scanning electron microscope to evaluate root canal filling remnants. A scoring system was utilized to quantify the amount of residual filling material at the three predetermined portions of each root canal
VisiterLa résine flexible a été utilisé en prothèse adjointe depuis les années cinquante. Ces propriétés sont améliorées par renforcement avec des fibres de verre. Les études ont montrés qu’elle présente une grande résistance à la fracture, un faible module d’élasticité à l’origine de sa flexibilité et une moindre résistance à la flexion à la limite proportionnelle. Les propriétés physiques de la résine flexible sont favorables pour être utilisé comme un matériau de base de prothèse. Les prothèses adjointes flexibles apportent plus de confort et d’esthétique aux patients et elles trouvent ses indications dans plusieurs situations cliniques qu’on va les illustrées à travers une série de cas cliniques.
