11NOTESAbsence of two initial beeps and noprogress of the file indicate faultyconnection: Disconnect the measurement cablefrom the patient. Check proper connection betweenthe measurement cable and theaccessories. Clean the file clip/touch probe contact. Irrigate the canal, if necessary, andstart again. Verify lip clip contact with the patient. Ensure the lip clip is in contact withmoist tissue.Fig. 10 Coronal / medial sectionApical SectionZoomed view of the file progression is shown onthe enlarged image of the apical part of the canal– the Apical Zoom (Fig. 11).WARNINGS Do not continue the measurement ifthe initial 2 beeps are not emitted. Go to the Settings Menu andselect the CHECK Mode to verify theperformance of the device.7.4.3 Apex LocalizationWARNINGAs with all electronic lengthdetermination devices, the bars shownin the apical zoom do not represent thedistance in millimeters.Fig. 11 Apical section - blueIn the apical section the indication line indicatesthe exact position and changes accordingly fromblue to green and then to yellow (Fig. 12, Fig. 13).Coronal and Mid RootSlowly insert the measuring file into the canal.File movement along the coronal and medialsection towards the apical region is representedon the full canal image by the ellipse continuouslymoving down (Fig. 10).Fig. 12 Apical section - green

12Over instrumentationOnce the file tip has passed the apical foramen,the warning red dot appears beneath the apicalzoom image and short warning beeps will sound(Fig. 15).Fig. 13 Apical section - yellowFile movement in the Apical Zoom isaccompanied by audio signals, which serve asadditional indication of the file tip position. Theinterval between the beeps becomes shorter themore the file approaches the apex.When the file tip reaches the apical foramenthe indication line is marked red and a constantsound is emitted (Fig. 14).Fig. 15 Apical foramen is passed - red dotInterruption of measurementDuring the length determination the file clip maybe disconnected from the file and reconnected atany time (e.g. when the file is changed to a largersize or when the length of another canal shouldbe determined). The device detects automaticallythat a new length determination cycle is initiatedand indicates it with two short beeps.Completion of measurementFig. 14 Apical foramen – red bar Before unplugging the measurement cablefrom the device receptacle, disconnect the lip clipand the file clip from patient. Move the file stopper to the selected referencepoint on the tooth. Gently remove the file from the canal andmeasure the apical length between the stopperand the file tip.NOTEThe apical indication line shows thefile tip position inside the canal: blue section:zone approaching the apical region green to yellow sections:apical region red bar: apical foramen7.4.4 Sound Level SelectionTo adjust the sound volume of ProMark , tap thesound icon on the screen (Fig. 16).

13Fig. 18 Standby mode screenFig. 16 Tap the sound iconAdjust the preferred sound volume (Fig.17). Thesound volume refers to the warning beeps and tothe ON/OFF button melody.NOTETo prolong the lifetime of the battery, itis recommended to switch the device offafter each measurement. Once deviceswitches off completely, you must pressthe power button to turn the unit back on.7.5 Length DeterminationThe working length should usually be determinedat the third green bar (Fig. 12).Fig. 17 Select the sound volumeNOTEWhen ProMark is turned off, the selectedsound volume is stored in the devicememory and is activated automaticallywhen the device is switched on.7.4.5 Automatic ShutdownProMark automatically goes into a standby modeafter 3 minutes of inactivity. The display will beblank except for a blinking standby symbol. Torevive the device simply press the touchscreendisplay, connect the probes or begin to take ameasurement. You do not need to switch thedevice on again.After 20 minutes of inactivity the ProMark willautomatically switch off completely (Fig. 18).Since the working length must always bespecified in consideration of the respectivepathological situation (vital or non-vital) and inaccordance with the clinician’s experience, theworking length may vary between the first greenand last yellow bars.Since the irrigating solution used has a smallinfluence on determining the working length, werecommend:a) determining the length in a slightly moist canaland/orb) determining the length in a canal using salinesolutions, low percentage (e.g. 2%) sodiumhypochlorite, or QMix 2in1 irrigating solution.NOTEDetermining the working length can bedone while filled with irrigating solutionsas well as in a somewhat dry canal.

14After electric length determination and settingthe stopper, the metric working (in mm) lengthshould be determined with the help of ameasuring gauge.Once the canal length has been pinpointed,adjust the rubber stopper on the file to anappropriate adjacent cusp before removing thefile from the canal.7.5.1 TroubleshootingPlease review the following list to betterunderstand potential causes for inconsistentreadings:Too fast movement or even jumping to the apexmay be caused by any of the following:SymptomSolutionExcess liquid in thepulp chamber or rootcanal (irrigating solution,blood or saliva), cancreate wrong conductivepath and incorrectmeasurements.Dry the access cavitywith a cotton pellet/air-blower.Wait until excessbleeding has stopped.Gingival proliferationcan lead to direct contactwith the measuringfile causing a shortcircuit and incorrectmeasurements.Isolate the access cavityby: adequate preparationfilling. placing a rubber dam. electrocauterizing.The measuring filecontacting metallicrestorations (crown,posts, amalgam filling)can cause a shortcircuit and incorrectmeasurements.Carefully enlarge theaccess cavity and isolatewith flow composite.Carefully widen theopening at the top of thecrown.Too slow or extremely delayed movement isindicated for the following reasons:SymptomSolutionAn obliterated canal canimpede the conductivepath, preventing normaldevice function. Check the comparativex-ray for hints. Recapitulate with asmall hand file untilreaching working length.Blockage by oldcanal filling materialresidue can impede theconductive path andprevent normal devicefunction. Take an x-ray tore-check and try tocompletely remove theold canal filling materialprior to measuring.Blockage by remnantsof a medicatedsubstance (e.g. calciumhydroxide) can impedethe conductive path andprevent normal devicefunction.Completely removethe remnants prior tomeasuring.Extremely dry canals orpatient's dry mouth canimpede the conductivepath and prevent normaldevice function.Rinse root canal spacewith irrigating solution.Dry the access cavitywith a cotton pellet/ airblower. For dry mouth,use water spray.WARNINGIn some cases precise determination offile position cannot be obtained. Here aresome scenarios: Special condition symptom: Exceptionallylarge apical foramen due to lesion orincomplete formation May lead to shorter measurementthan the actual length. Root fracture or perforation May lead to incorrect measurements.

157.5.2 Comparison of electronic lengthdetermination versus radiographyTo select the settings features, use the scrollingbar (Fig. 20). (see 6 features in chapter 7.6.1).X-ray radiography represents two-dimensionalprojection of three-dimensional root canalsystem. There are some cases when theradiographic length and the electronic length donot match.Fig. 20 Scroll between settingsIn the case of a lateral canal curvature the x-raymay show a shorter working length than obtainedwith ProMark .To exit the Settings Menu, tap the back arrow iconor the ProMark “home” icon (Fig. 21).7.6 Device SetupTo enter the Settings Menu, tap the settings icon(Fig. 19).Fig. 21 Exit settings menuFig. 19 Tap the settings icon
