Operating microscope in Endodontics (Root canal treatment)\"\"<\/strong><\/p>\n

The practice of endodontics requires precision and big attention to detail. These depend on the training, abilities, and experience of the physician. The majority of endodontic procedures are done in confined and dark spaces, and a fraction of a millimeter can determine the result of the treatment. In the past decades, endodontics has gained not only basic and clinical scientific knowledge, but also has benefited from huge technological advances. Due to the intricate nature of endodontic treatment, professionals have always seeked to improve the view of the operative field or work area.<\/span><\/p>\n

Advantages of Dental Microscopes<\/strong><\/p>\n

A better visualization requires improved magnification and illuminations, and the microscopes, as well as the loups, have been widely adopted. The dental microscopes possess a variety of advantages compared to the loups. Because the microscopes are units with their own support, the increase of lenses and prisms is not an inconvenience. This has significant implications regarding ergonomics and visualization.<\/span><\/p>\n

Microscopes provide an adjustable magnification in a range of approximately 2x to 25x, while most loups provide a fixed magnification between 2,5x and 6x. The magnification can be divided into low (~2x-8x), medium (~8x-16x), and high (~16x-25x). The low, medium, and high magnifications are applicable to the different stages of procedures in surgical and not surgical endodontic treatments.<\/span><\/p>\n

The use of a microscope increases significatively the operator\u2019s precision.<\/strong><\/p>\n

Uses of the Microscope in Non-Surgical Procedures: For the endodontics specialist, the dental microscope is useful for the diagnosis and clinical procedures. During the diagnosis, the microscope can help in identifying caries, insufficient margins of restorations and crowns, or in the evaluation of fissures or fracture lines. During root canal therapy, the magnification and illumination provided by the operating microscope helps in the removal of caries, access preparation, removal of calcifications, identification of main root canal and accessories, identification of fissures and fracture lines, and in the internal resorption treatment. Under the microscope, subtle color and texture changes become apparent, allowing the professional to perform the procedures with more security.<\/span><\/p>\n

High magnification can help in the localization and instrumentation of obstructed and calcified roots, in the identification of bifurcations, in the removal of obstructions such as calcifications, in the evaluation of the correct preparation and removal of remaining pulp tissue and root filling.<\/span><\/p>\n

Increased visualization also helps in the treatment of dental anomalies, such as fused teeth or dens in dente, among others. In the re-treatments, the microscope is useful in the identification and removal of filling materials such as sealant, pastes or gutta-percha, silver cones, bolts, or fracture instruments. It also helps in the non-surgical reparation of perforations, allowing the cleaning and placement of the reparation material to be done with more precision.<\/span><\/p>\n

Uses of the Microscope in Surgical Procedures\"\"<\/strong><\/p>\n

Surgical endodontics has been completely transformed by the microscopic procedures. The incorporation of the microscope, alongside the use of ultrasonic tips and biocompatible filling materials, has evolved the classic apicoectomy into the modern endodontic microsurgery. All of the steps in endodontic microsurgery are carried out under different degrees of magnification, including the flap preparation, osteotomy, identification of root apices, resection of the root end, removal of inflammatory tissue, observation of the sectioned surface, preparation and filling of the root end, and suture. The microscope is also useful for the reparation of cervical or external reabsorptions and of perforations.<\/span><\/p>\n

Conclusion<\/strong><\/p>\n

The dental operating microscope has become an integral part of the practice of\u00a0 endodontics.<\/span><\/p>\n

For surgical and non-surgical endodontic therapy, excellence is essential. Besides the obvious benefits for the clinical practice, literature demonstrates the increase of success rates in endodontic treatments (surgical and non-surgical) when done with the microscope, in comparison to the ones done with loups or without magnification.\u00a0<\/span><\/p>\n

The treatments carried out with the use of the operating dental microscope result in superior care for the patients, and modern endodontic therapy is more effective due to its use.<\/span><\/p>\n

Electronic Foramen Locator in Endodontics (Root canal Treatment)<\/strong><\/p>\n

The presence of microorganisms inside the root canal system is generally accepted as the main cause of the failure of endodontic treatments, also known as root canal treatment. Thus, maximum cleaning and disinfection, and filling until the precise limit of the root canal are fundamental. Moreover, apical constriction (fig. 1) is considered by general rule as the anatomical reference point, until where the instrumentation and filling must reach. However, locating the apical constriction, from a clinical perspective, is very hard, due to the fact that its position and formation are highly variable.<\/span><\/p>\n

Working length<\/strong><\/p>\n

The distance between the coronal reference point and the apical constriction is known in endodontics as \u201cworking length\u201d. The methods to determine the working length include tactile sensibility, the knowledge of the different canals\u2019 lengths and their anatomy, the evaluation of X-rays prior to the procedure, and the electronic foramen locators. Traditionally, X-rays have been the most used method to obtain information on the anatomy of the root canal and surrounding tissue.<\/span><\/p>\n

The correct determination of the working length is fundamental for the complete cleaning, disinfection, and filling of the root canal, as well as for the prevention of mistakes in the procedure that may affect the final result of the treatment.<\/span><\/p>\n

Disadvantages of the traditional X-ray method<\/strong><\/p>\n

The measurement of the working length performed by X-ray has several limitations:\u00a0<\/span><\/p>\n
