What are the major indicators of successful endodontic treatment?
The six criteria are as follows: (1) initial nonsurgical root canal treatment, (2) use of Periapical Index score of one or two to denote success, (3) use of periapical radiograph or cone-beam computed tomography (CBCT) to determine the periapical index value, (4) a minimum follow-up period of 6 months, (5) success or ...
How do apex locators work in endodontics?
All apex locators have two electrodes, one connected to an endodontic instrument, the other connected to the patient's body. The electrical circuit is completed when the instrument is inserted into the root canal in the apical direction and touches the periodontal tissues.

How do you determine endodontic prognosis?
In determining prognosis for endodontic treatment, the dentist should be able to forecast the outcome of initial nonsurgical root canal treatment, based on the pulp and periapical diagnosis, tooth anatomy and morphology, remaining tooth structure, and periodontal support.
When do you use apex locator?
An apex locator is an electronic equipment which is used in an endodontic procedure to locate the apical constriction and then gauge the length of the root canal space. The tip of the root is resistant to electrical current.

Why is endodontics so difficult?
There is no doubt that magnification of the pulp chamber greatly assists in finding and accessing narrow canal orifices , and many practitioners now routinely use loupes, as seen in Figure 30. This one purchase has made huge improvements in the quality and ease of endodontic treatment for many practitioners. Indeed, the improved vision gained from the use of loupes improves all aspects of general dental practice, not just endodontics. The patient in the illustration is merely undergoing a routine examination.
Why do endodontists use parallel radiography?
Long-cone parallel radiography is a requirement for endodontics, 1 because it gives an undistorted view of the teeth and surrounding structures and is repeatable, thus allowing more accurate assessment of periapical healing. The bisecting angle technique should no longer be employed. It is further recommended that rectangular collimation be fitted on all new radiographic equipment, and retro-fitted to existing equipment as soon as possible. There are many beam-aiming devices available to hold the x-ray film parallel to the tooth. Figure 5 shows an example of a popular holder, with a special cage attachment to fit over a rubber dam clamp.
What is the best solution for root canal irrigation?
It is generally accepted in endodontic practice that sodium hypochlorite is the most suitable solution for irrigation of the root canal system. Normal household bleach is approximately 5.5% sodium hypochlorite solution, and this may be diluted with purified water up to five times to the operator's preference.
What is a handpiece for root canal cutting?
Handpieces providing a mechanical movement to the root canal cutting instrument have been available since 1964. Their function was primarily a reciprocating action through 90° and/or a vertical movement, according to the design and make. Because steel files do not have the flexibility necessary for rotary movements in a curved canal without damaging the canal configuration, these instruments were never really acceptable in endodontic practice.
What is sensor plate?
A sensor plate, appropriately sterilized and sealed, is used in place of the conventional film. The sensor may be either directly linked to the computer, or resemble a conventional periapical film packet. The resultant image is digitally processed and projected upon the computer screen in a matter of seconds.
What is a furcation probe?
A furcation probe is useful to check for the presence of furcation involvement. Other items usually included are a flat plastic, sterile cotton wool rolls, sterile cotton wool pledgets, artery forceps to grip a periapical radiograph and a metal ruler, or other measuring device that may be sterilized.

For many years the standard cutting instruments have been the reamer, K-type file and Hedstroem file. These root canal preparation instruments have been manufactured to a size and type advised by the International Standards Organisation (ISO).
What drill bit is used to open a root canal?
Gates-Glidden drills. This kind of drill bit helps to further open the canal, particular in molars. They are also used during root canal retreatment to remove gutta-percha, which is a putty-like material commonly used to fill root canals.
What instrument is used to remove calcified canals?
Ultrasonic Instruments. These tools can be used to uncover calcified canals and remove restorative and endodontic materials from the canal space within the tooth. These instruments operate through vibration and emit a high pitched sound that can be surprising when they are first turned on.
What is root canal?
Root canals are complex dental procedures that require a variety of specialized tools. Your endodontist may use some or all of the following during your root canal procedure.
What is the most accurate diagnostic aid for root canal treatment?
Radiographs are the most accurate and least subjective diagnostic aids available to endodontists for diagnosis of diseases affecting the maxilla and mandible. Conventional X-rays using an analog film or digital receptor produce two-dimensional (2D) image of a three-dimensional (3D) object. The anatomical structures surrounding the tooth, superimpose and make it difficult to interpret the conventional X-ray image. [ 1 – 3] Radiographs are an important part of root canal therapy, especially for diagnosis, treatment, and follow-up. However, routine radiographic procedures do not accurately demonstrate the presence of every lesion, the real size of the lesion or its spatial relationship with the anatomical structures. [ 4] Newer imaging techniques in use include: Digital imaging systems (Direct, Indirect, Optically scanned), Computed tomography (CT), Tuned aperture computed tomography (TACT), Localized computed tomography (micro-computed tomography), Ultrasonography, Magnetic resonance Imaging (MRI), Radioisotope imaging, Single photon emission computed tomography (SPECT), Positron emission tomography (PET), Cone beam volumetric tomography (CBVT), Radio visiography (RVG), and Denta scan. [ 5 – 7]
Why are radiographs important for root canals?
[ 1 – 3] Radiographs are an important part of root canal therapy, especially for diagnosis, treatment, and follow-up.
Is CBCT a reliable imaging method?
Although CBCT technology is efficient in imaging hard tissue, it is not very reliable in the imaging of soft tissue, as a result of the lack of dynamic range of the x0 -ray detector. Availability of Cone beam computed tomography is limited to major metropolitan areas at present.
Can a CT scan detect a fractured tooth?
CT scan is excellent in detecting vertical root fractures or split teeth as periapical radiograph can rarely detect them. CT can also be used to localize foreign bodies in the jaws.
Can a CT scan show apical periodontitis?
Chronic apical periodontitis can be seen with the CT scan, both in the early and established stages. It is seen as an enlargement of the periodontal space, which is seen as a small osteolytic reaction around the root tips. Further expansion of the pathological reaction in the cancellous and cortical bone may easily be seen both on the axial scans and on the reconstructed images, including a detailed visualization of the involvement or erosion of the cortical plates.
Can CBCT detect periapical disease?
Periapical disease may be detected early using CBCT compared to the periapical views, and the true size, extent, nature, and position of periapical and resorptive lesions can be assessed. Root fractures, root canal anatomy, and the true nature of the alveolar bone topography around the teeth may be assessed.

Why do endodontists use radiographs?
There is no doubt that radiography is one of the cornerstones of endodontics. We use radiographs to aid diagnosis, during endodontic treatment, to judge the quality of the root treatment we have just completed, and to monitor healing.
Can X-rays penetrate the maxilla?
The X-rays are likely to have penetrated through far more bone in the maxilla of a 6-foot rugby forward than a small 70-year-old lady, so the timer should be adjusted accordingly. Often the exposure has to be increased slightly to improve image quality for endodontics. Film or digital.
Can a large film be used on anterior teeth?
Where there is a large lesion associated with an anterior tooth, the complete lesion may not be captured on a small receptor, so if there are no anatomical constraints, a large film can be used (Figures 2A and 2B).
