How to use your apex locator

Getting Started:

1. Disconnect the charger from the in­strument if connected.(Fig.6)
2. Connect the measurement wire and switch on the instrument, two tones of audio signal are emitted when the unit is turned on.(Fig.7)
3. Switch to apex locator mode by suc­cessive presses on the MODE SWI­TCH button, visual information appears appear indicates that the apex locator is ready for use. (Fig.8)
4. Link the lip clip to the patient.(Fig.9)
5. Insert the file into the canal. (Fig .10)
6. Connect the file holder to the file.(Fig.11)

Note

• No other specific adjustment is necessary before commencing measurement.

Set flash bar

• The position of the flash bar can be set as guide for canal measurement and enlargement.(Fig.12)
• The reference point for measurement of enlargement can be set anywhere between 2 and APEX.(Fig.13)
• When the file reaches the position 2.0mm away from the apex of the root­canal, there will be a continuous alarm. (Fig.14)
• During measurement, information dis­play the number of bars left before flash b­ar is reached.
• Set method: flash bar can be set in free state of ap­ex locator mode, press set button and the reference position will change and be memorized automatically. (Fig.15)

Memory bar

• During operation, dentist can memory the current position of the file tip. It can be used to mark the beginning of a sharp curve or some certain distance from the apex. It can also be used as a guide when the file size is changed for canal enlargement. (Fig .16)
• Memory bar can’t be shown on screen during measurement. In free state, memory bar will appear and the information displays the bars number from the memory bar to the flash bar.(Fig .17)

Set method

• The memory bar can be set by press the set button in measurement state. (Fig.18)

Operation method

1. Free state ( without measurement ) In apex locator mode, if the file isn’t inserted into root canal, the screen dis­plays the memory bar and the flash bar, the information display the bars numb­er from the memory bar to the flash bar. (Fig.19)
   • Meter of 1,2,3 show that the distance from the apex is not in mm as a unit, but it mean that file tip is near the a­pex hole.
   • Information display: Number of ba­rs left before flash bar is reached (during measurement). (Fig.20)
   • The bars number from the memory bar to the flash bar (in free state). (Fig.21)
   • The information shows not the root canal length, but the number of bars.
2. Pre-apical zone (2 – 3mm away fro­m the apex of root canal)
   • The meter is activated when the file is inserted into a root canal. The numb­er of bars remaining before the file re­aches the flash bar is shown by the in­formation display. (Fig.22)
3. Narrow zone (0.5 – 1 mm away from the apex of root-canal)
   • When the file tip reaches a position near the apex, on the screen, the bar color changes to green to indicate you have reached a narrow zone. The number of bars remaining before the file reaches the flash bar is shown by the information display. (Fig.23)
4. Apical zone (0.5-0mm away from the apex of root-canal)
   • When the file tip approaches the apical zone, the green triangle is flashing indicates the point set for reference. At this point, please fasten the file with the rubber vernier caliper on the reference point of the tooth crest rather than keep up probing into the root-canal. (Fig.24)
5. Beyond the apex
   • The position of the apex is represented by the word “APEX” and information display”–“.The meter bars in this area are pink, indicating that you have passed the Apex (Fig.25)

Deciding the working length of root canal

• Measure the distance from the bottom of rubber vernier caliper to the tip of the file. Note down this distance.
• So subtract 0.5-1.0mm from the above data is the working length of root canal.

REMARKS

• The working length of root-canal varies from each other for the reason of different shapes of teeth and root canal.

Check the instrument

• Dentist should check the instrument at least once a week to make sure it is working properly.
• In free state of apex locator mode, press the set button about 1 Os, LCD display in Fig.26, means the instrument entered the test state. Please confirm the bar is at which up and down the green triangle within 3 steps, otherwise it can not test correctly. (Fig.27)
• In test state, measurement is not available.
• Power off the instrument, connect the test wire to the main unit. (Fig .28)
• Connect the file holder, stainless clip to the test wire.
• Contact with the file holder and stainless clip, (Fig. 29)Confirm all the bars displayed on screen and the green triangle is flashing. (Fig. 30).

Precautions for Apex Locator Use

• To ensure that short circuits do not impair the measurements, be particularly careful with patients fitted with metal crowns or bridges.
• Avoid excessive liquids inside the tooth cavity to prevent overflow and incorrect measurements.
• Make sure that the canal is wet enough to ensure reliability of the measurement.
• Ensure that the file does not touch another instrument.
• Measurements in canals with open apex may provide results with reduced precision.
• The result of measurement is for reference only, dentist should check by X-ray film.
• Sometimes, bars will unusually shake in the moment of the file inserted into the root canal, and when the file tip moved in the direction of apex, the result will get right.

How to use your pulp tester

Preparation

1. Disconnect the charger from the instrument if connected.(Fig.31)
2. Connect the test handle and switch on the instrument, two tones audio signal are emitted when the unit is turned on.(Fig.32)
3. Switch to pulp tester mode by successive presses on the MODE SWITCH button, visual information appears, indicating that the pulp tester is ready for use (Fig.33).
4. Link the lip clip to the patient’s lip; instead the patient may hold the lip clip firmly in the hand.(Fig.34)
5. Insert the tooth probe into the handle. (Fig.35)

Note: no other specific adjustment is necessary before commencing test.

Getting Started

1. Clean and dry the tooth to be tested.
2. To improve contact between tooth and probe, apply a little prophy paste or toothpaste to the metal tip.
3. Place the probe on the middle of the labial or lingual surface of the tooth. Avoid soft tissue and restorations such as crowns, amalgams or composites.
4. When the probe contact tooth unquestionably, the unit activated automatically. The number will indicate that an increasing GentlePulse stimulus is being applied to the tooth.
5. When the patient feels the stimulus, leave the probe from the tooth. The stimulus will stop immediately. The display will flash and hold the final reading for approximately 5 seconds, so it can be noted, at this time contact tooth again, the unit will apply stimulus continuative. After 5 seconds the unit will automatically turn to ready status.
6. During 20-50, beeper emits tone slowly. During 50-80, emits tone faster. After 80,emits a fastest tone.

Clinical Observations

1. The reading corresponding to the normal stimulus is 1-99, is estimated that the tooth is vital (Fig.36).
2. No sensation at the maximum stimulus(–) suggests that the tooth is non -vital, This conclusion should be confirmed by thermal testing.(Fig.37)
3. Generally, incisors have similar thresholds about 10 -30, premolars about 25 – 45, molars about 35 – 70.
4. Molars generally require greater stimulus than premolars, but the threshold may also be affected by such factors as the age of the patient, trauma and pathology.
