Introduction: Instrument separation is one of the most stressful endodontic mishaps, that can occur any time during the root canal treatment. Several techniques have been employed to facilitate instrument retrieval, however, most of them are technique sensitive, expensive and require great expertise. It is possible to successfully remove broken file from the root canal using sonic agitation coupled with H-files with minimal damage to radicular dentin, if the file separation is in the straight and visible part of the canal. Case Report: A 29-year-old man reported to the Department of Conservative Dentistry and Endodontics, with a chief complaint of pain in the upper front teeth for which the patient had undergone previous dental treatment, but with no relief in pain. The patient gave a history of treatment in the same tooth at a private clinic 3 months back. Conclusion: The technique used in this case report might be considered a conservative, secure, simple and low-cost option that can be performed by any professional in the day-to-day of the endodontic clinic.
INTRODUCTIONInferior myocardial infarctions account for 40 to 50 % of all acute myocardial infarctions and are generally viewed as having a more favourable prognosis than anterior wall infarctions.1-3 Nearly 50% of patients suffering from inferior wall myocardial infarction, usually experience hemodynamic and bradycardiac complications.1 Anterior wall myocardial infarction invariably occurred by occlusion of the left anterior descending coronary artery.However inferior wall myocardial infarction can result from occlusion of either the right coronary artery or left circumflex coronary artery. 4 Right ventricular myocardial ABSTRACTBackground: Inferior myocardial infarctions account for 40 to 50% of all acute myocardial infarctions and are generally viewed as having a more favorable prognosis than anterior wall infarctions. The management, and in some instances, prevention of these complications, may be facilitated by early differentiation between AMI caused by RCA versus left circumflex coronary artery occlusion. These can be diagnosed from the electrocardiography (ECG) which remains a valuable and most widely used rational modality to diagnose and risk stratifying in an acute setting. The present study helps in Electrocardiographic differentiation between right coronary and the left circumflex coronary arterial occlusion in isolated inferior wall myocardial infarction. Results:Out of 52 patients of acute inferior wall myocardial infraction, 41 were males and 11 were females. Thus the male to female ratio is 3.72:1. In the above table, the ST segment elevation in lead III was more than lead ii in42 patients. All these 42 patients were found to have RCA as the culprit vessel. The St Segment elevation in lead II was more than lead III in 9 patients. All these 9 patients were found to have LCx as the culprit vessel. Conclusions:The incidence of acute inferior wall myocardial infarction is highest in age group of 50 to 59 years. The ST segment elevation in acute isolated inferior wall myocardial infarction was greater in lead III than in lead II when right coronary artery was the culprit vessel and vice versa when the left circumflex coronary artery was the culprit vessel. ST segment depression in lead I was common when the right coronary artery was the culprit vessel and not seen with left circumflex coronary artery occlusion. An upright T wave in lead V4R in acute isolated inferior wall myocardial infarction was common when the right coronary artery was the culprit vessel and not seen with left circumflex coronary artery occlusion.
Objective:The study was done to evaluate the antibacterial effects of three fluoride releasing restorative materials, namely seventh generation dentin bonding agent (Futurabond ® DC, Voco, Germany), resin modified glass ionomer cement (GC Fuji II™ LC, GC Corporation, Tokyo) and Nanoionomer (Ketac™ N100) against Lactobacillus acidophilus [Microbial Type Culture Collection, 10307] and Streptococcus mutans [Microbial Type Culture Collection, 497]. Materials and Methods:The antibacterial effect was analysed using agar diffusion test. The experimental groups were three fluoride releasing restorative materials and control against Lactobacillus acidophilus (MTCC 10307) (Group A) and Streptococcus mutans (MTCC 497) (Group B). The wells in petri dishes were filled with chlorhexidine, resin modified glass ionomer, nanoionomer, bonding agent and were dropped with micropipettes in paper disks, blown dry and light cured. The culture plates were incubated for 24h at 37°c. The antibacterial effect was checked after 24h, 48h and 7days in triplicates.. Results and Conclusion:The results were collected, and statistically analyzed using the ANOVA test to determine the difference between the mean diameters of the inhibition zone observed. All the three restorative materials showed antibacterial activity against Streptococcus mutans and Lactobacillus acidophilus. The antibacterial effect for resin modified glass ionomer and nanoionomer decreased over a period of 7 days whereas for dentin bonding agent there was an increase in the antibacterial effect seen from 24 hours to 48 hours.
Introduction: Crown fracture is the most common traumatic injury which affects the permanent teeth. Most commonly affected teeth are maxillary incisors, accounting for 96% of all crown fractures. Children and adolescents usually suffer from traumatic injuries, with boys being affected more commonly than girls. Missing tooth structure causes emotional trauma to the children. Rehabilitation of both esthetics and function is the principal objective of the treatment in such cases. Direct composite restorations and indirect ceramic restorations is the primary line of treatment for restoring anterior teeth after fracture when it is not possible to reattach the tooth fragment. The treatment options in uncomplicated coronal fractures depend on various factors such as the amount of residual dentinal enamel tissue, the relationship with the gingival profiles, and the age of the patient. Case Report: This case report describes the clinical procedure involved in the treatment of a complicated fracture in the maxillary left central incisor in a 17-year-old female patient, due to accidental fall. After clinical and radiograph examination Ellis class III fracture was diagnosed. Endodontic treatment was carried out followed by post endodontic restoration. Conclusion: Composite resins have proven themselves as one of the most important tools in the clinician’s armament. Reliable strength and a realistic aesthetic result is achievable. The advantage of this technique is closely associated with satisfactory results, combined with the dexterity, skill and mastery of technique employed by the professional.
Introduction: Endodontic management of immature permanent teeth is a challenge for both clinicians and researchers. Open apex is an unusual wide apical foramen that results due to multiple reasons such as incomplete development, extensive apical resorption, caries leading to pulpal necrosis or trauma before complete root formation, root-end resection, or due to over instrumentation. Aims: To prevent the risk of subsequent microbial contamination. Case Report: This article is a case report showing the management of open apex with MTA plug and a thermoplasticized Gutta Percha technique for obturation. Discussion: Traditionally, calcium hydroxide was used for inducing the formation of an apical barrier. Conclusion: Currently, biomimetic materials like mineral trioxide aggregate (MTA) and biodentin have shown promising results for apexification procedures.
