How accurate is apex locator?
Figure 4
| Apex locators | Constriction | |
|---|---|---|
| ±0.1 mm | ±0.5 mm | |
| Mini Apex Locator® | 49% (38–59%) | 98% (92–99%) |
| ProPex® II | 49% (38–59%) | 95% (88–98%) |
| Prototype (VDW) | 38% (29–49%) | 90% (82–95%) |
Can apex locator detect perforation?
The ProPex II, Elements Apex Locator, and RayPex 6 detected 14 of 15 perforations (93% sensitivity; 95% confidence interval [68%;100%]).
How does a dental apex locator work?
Electronic apex locators use an electrical circuit through the patient’s root canal and oral tissues to determine the location of the apical foramen. In order to set the ideal apical limit, it is necessary and unavoidable to perform conductometry.
What is Rotary root canal?
Rotary endodontics involved an electrically-powered instrument which performs the root canal treatment and replaces the traditional stainless-steel manual files. The tip of the electric hand tool used is made out of nickel titanium – a material that is five times more flexible than traditional stainless steel.
Which size of file is the best with an apex locator?
Based on this result, it can be suggested that size 15 K-file is a more suitable size for determining working length using Raypex 5 apex locator. The range of ± 0.5 mm to the foramen has been considered as the strictest acceptable range. Thus, measurements attained within this tolerance are considered highly accurate.
How do you calibrate an apex locator?
Make sure that you are getting your initial reading by taking your file a little long to read the PDL, then back up your file short of working length, then re-advance it to your zero zero. This will “calibrate” your apex locator and will give you a more accurate reading.
How do I know how long my root canal will work?
There are several ways to determine the working length of the root canal viz radiographs, electronic apex locators, tactile sense, patient response, knowledge and experience, predetermined normal tooth length, use of paper points, mathematical equations etc.
How do you diagnose a perforated canal?
Signs and Symptoms of Perforations:
- Sudden bleeding and pain during instrumentation of root canals or post preparations in teeth are warning signals of a potential root perforation.
- Suppurations resulting in tender teeth, abscesses, and sinus tract including bone resorptive processes may occur.
What is the use of apex locator in dentistry?
Apex locators can be used to determine if the perforation communicates with the periodontal membrane, This is based on Sunada’s2 findings that the electrical resistance between the mucous membrane and the periodontium can be considered to have a constant relationship.
How does electronic apex locator work?
Essentially, electronic apex locators work by using the body to complete an electrical circuit. One side of the apex locator is connected to the oral mucosa (via a lip clip) and the other side to the file.
How does the Root ZX work?
The circuit of Root ZX is mainly based on detecting the changes in electrical capacitance in the vicinity of the AF. It works by calculating the impedance ratio of two simultaneously produced frequencies (0.4 and 8 kHz). The ratio represents a definite value that reflects the file position inside the canal.
How does apex locator calculate work length?
The best working length is found by subtracting approximately 0.5 mm from the length obtained with the apex locator. It is important to know that there is potential for interference of an electronic apex locator with a patient’s cardiac pacemaker function.
What are two methods that the dentist can use to measure the root canal?
At present the modalities being used for the measurement of root canal length are radiographs and tactile sensation. With radiographs an accurate estimate is difficult, especially in curved canals. Feeling the apex with an instrument (tactile) requires skill, experience and cannot be considered absolutely accurate.
Which perforation location has the best prognosis?
A small root perforation, sealed immediately and apical to the crest bone and epithelial attachment, presents with a better prognosis.
