| Frage | Antworten |
| Burnisher =smooth off rough margins of restoration, remove any scratches, emphasise grooves | |
| Flat plastic = deliver materials into the cavity preparation and to manipulate plastic material | |
| William's probe = identify the depth of the sulcus or periodontal pocket. This probe is graded at 1, 2, 3, 5, 7, 8, 9 and 10 mm. | |
| Gingival Margin Trimmer = for the horizontal finishing of outter cavity margins | |
| Green Gracey Curette (7/8) - Buccal and palatal/lingual surfaces of posterior teeth | |
| Blue Gracey Curette (13/14) - Distal surfaces of posterior teeth | |
| Brown Gracey curette (15/16) - Mesial surfaces of difficult molars | |
| Dark blue/purple Gracey curette (17/18) - Distal surfaces of difficult molars | |
| Polishing Discs = polishing composite restorations, more aesthetically pleasing and smoother on tongue | |
| Cavitron (UltraSonic Scaler) - to remove calculus and root surface debridement - clean out periodontal pockets | |
| IRM = used to fill access opening. powder and liquid mixed to make a thick putty-like paste | |
| Rubber dam (forceps/hole puncher/frame) = used to isolate teeth during operative dental procedures+endodontics | |
| Light Grey Gracey Curette (1/2) - All surfaces of anterior teeth | |
| Dark grey Gracey curette (3/4) - All surfaces of anterior teeth (for heavier deposits) | |
| Orange Gracey Curette (11/12) - Mesial surfaces of posterior teeth | |
| Silicone Stoppers = to set working lengths on files | |
| Gutta Percha = used to obturate prepared canals (we used 0.02 taper cones) | |
| Endodontic explorer = sharp, used to locate canal orifices | |
| Endodontic ruler = used to set lengths on files and gutta percha points. | |
| Paper Points = used to dry fluids from canals | |
| Finger Spreader = used to laterally condense gutta percha during obturation of canal | |
| Barbed broaches = for removal of pulp tissue form wide canals | |
| Reamers = shaving canal wall via 'half twist and pull' motion | |
| K Files = twisting triangular or square cross section, used by reaming or push-pull action. | |
| K flex-files = rhomboid cross section, alternate sharp and non cutting edges, improved flexibility and reservoir for debris. | |
| Hedstrom file = round cross sectional blank, only push-pull action. | |
| Nickel-Titanium files = superelasticity and memory. (resistant to torsional force) | |
| Greater Taper hand files = creation of pre-determined funnel shaped canal with the use of fewer files. clockwise+anticlockwise going closer into apex (no need for stepback) | |
| What design features do rotary instruments have? | Variable taper (dont have to use loads of different sized files to get desired taper) Flute design (determine cutting efficacy and debris removal) Non-cutting tips (reduce risk of apical transportation) Radial land (minimise file fracture and keep file centred in canal) |
| How to use rotary instrument? | Light pressure 5-10s each time then clean, irrigate, lubricate canal. 'Pecking motion' GG for coronol flare then small hand file to WL enlarging canal to 15-20 size. Then start with rotary |
| Gates Glidden = to flare up coronal section of canal, non end cutting and latch grip used in contra-angled hand piece. | |
| Excavator = removal of caries inside cavity | |
| Chisel = Get rid of enamel | |
| Explorer = find soft spots of caries, scrape plaque of debris off, detection of calculus or PRF on restoration (overhangs etc). | |
| Retract soft tissues Light reflection Indirect view of the teeth | |
| Syringe = To administer analgesia | |
| Air/Water Tip = inserted into a valve that will allow the dental professional to blow air or squirt water on the desired area in the mouth. (disposable or metal tip) | |
| Plugger = firmly pack the amalgam. This ensures all the air pockets are filled and allows the dentist to insert the maximum amount of amalgam. | |
| Carver = create smooth surface of amalgam and make it anatomically look like tooth. occlusion with other teeth are ok. | |
| Spatula = mix temporary fillings or glue | |
| Difference between gracey and universal currette? | Universal - two cutting edges. Gracey- one cutting edge (site specific). |
